Requirements are requirements, and the most popular type of connection is twisting. Where quick installation is required, terminal blocks of various shapes are used. One of the types of terminal connections is spring terminals. Wago products are especially popular.
To perform a tap without breaking the line, squeezes are used, which are called nuts among electricians. It is some type of terminal connection.
Using Terminal Blocks
The terminal block consists of contacts mounted on a plate of insulating material. The contact plate has a screw on both sides with which the wire is tightened. This allows you to press a copper wire on one side of the plate, and an aluminum wire on the other side, without fear of chemical interaction between these metals.
Can be connected different types wires On one side, a single-core wire can be attached to the plate, and on the other, a multi-core wire. Another problem that can be easily solved using a terminal block is connecting wires with different core diameters.
The terminal block can consist of one or more contact plates, which is very convenient in installation conditions. To do this, just collect the required number of plates and secure them in the right place.
Spring terminals
Terminals of this type are very similar in design to terminal blocks. The difference is that a spring-loaded plate is used as a clamp. Using spring terminals is very simple - you just need to strip the wire to the depth of the terminal.
The pressure plate is removed and the stripped wire is inserted into the terminal. The wire is inserted so that there are no exposed sections of the wire. Then the pressure plate snaps into place and the process is complete.
Spring terminals can be used to mount single-core, stranded wires and wires of different diameters. Installation of wires from different metals is allowed. The most widely used contacts are Wago contacts, which contain bimetal plates with a special contact paste against metal oxidation.
Installation of PPE caps
PPE caps are often used when installing wiring. In appearance, they are very similar to the back plastic cap of a ballpoint pen. A cone-shaped spring is placed inside it. The spring is coated with oxidation-resistant metal by anodizing.
To connect wires need to be stripped to a length of 10 - 15 mm and fold the stripped areas into one bundle. The ends of the bundle are inserted into the cap, which is then screwed onto them until it stops. The PPE cap can connect several wires, the total cross-section of which will not exceed 20 mm².
They are produced in different sizes, so choosing the ones you need is easy. The caps are color-coded, which is convenient for identifying phase or neutral wires.
| PPE brand | Number and cross-section of cores in mm² | Cap color |
| PPE – 1 | 2 x 1.5 | Grey |
| PPE – 2 | 3 x 1.5 | Blue |
| PPE – 3 | 2 x 2.5 | Orange |
| PPE – 4 | 4 x 2.5 | Yellow |
| PPE – 5 | 8 x 2.5 | Red |
PPE caps can significantly increase installation time because this connection does not require additional insulation. The cap material is made of non-flammable material and will not cause spontaneous combustion if overheated at the junction.
The quality of connection of PPE with caps is worse than with terminals and does not allow connecting wires of different metals.
Crimping with special sleeves
Where it is necessary to create a high-quality and reliable connection, special sleeves can be used. The sleeve is a piece of copper tube of the required diameter. The diameter of the sleeve is selected depending on the total diameter of the connected wires.
The stripped ends of the wires are inserted into the sleeve and clamped. Then a heat-shrinkable tube is put on the sleeve, which insulates this sleeve. If there is no heat shrink tube, you can use cambric or electrical tape. Wires can be inserted into the sleeve from one or both sides. For crimping, they try to use special hand press pliers.
With this connection, the sleeve cannot be used twice. During repairs, it is simply thrown away. If you use hand strippers and press pliers, you can perform installation with good productivity.
Soldering or welding
Installation using soldering is not used very often. Soldering always guarantees a reliable connection. The contact has low resistance and good mechanical strength. Soldered wires are less susceptible to damage due to ingress of moisture.
To connect by soldering, it is necessary to strip the wires by 40 - 50 mm, tin with rosin and twist. Then solder is applied to the twisted ends and heated until it spreads evenly over the entire twist and flows inside. Appearance The soldered wires should be shiny.
After soldering, the sharp ends are treated to prevent damage to the insulating material. Any available type can be used as insulation.
This connection can be considered the most labor-intensive. The soldering process requires certain skills. Installation in this way at a height using improvised means is not very convenient. When connecting by soldering, it is necessary to leave some reserve in case of repair.
In some cases, a connection using the contact welding method is used. The process itself is similar to the soldering method, but the stripped twisted wires are not coated with solder. A welding transformer is used for connection. The ends of the wires are heated until they fuse into one metal ball.
For insulation, put a heat-shrinkable tube or wrap it with electrical tape on the welded ends.
Stranding and insulation
The rules of the PUE completely reject twisting, but in practice, connecting wires by twisting is used almost everywhere. But you need to know how to twist, and then it will last for decades. To do this, strip the wires according to this calculation. That the twist should be at least 4 - 5 cm long.
The cleaned areas are cleaned of the oxide film with a knife blade or fine sandpaper. The ends of the wires are crossed at a certain angle at the end of the insulation and twisted tightly with pliers. The twist should be even and tight. From above it is insulated with existing insulation.
Twisted connections cannot be made for wires of different sections. Do not twist wires made of different metals. Twisting a single-core wire with a stranded wire is not allowed. This connection is used only where there is no fire-technical acceptance of repairs.
Walnut clamp
The nut-type branch clamp is designed for making branches from main wires without breaking. At the point where the outlet is connected, a section of insulation is removed and a “nut” is attached to this place. The clamp consists of a carbolite body and a steel clamp. The clamp consists of two plates and screws. Each plate has a recess for a certain cross-section of wire.
One plate is placed under the wire and covered with another plate on top. Both plates are clamped with screws, and between them there is a wire and a tap. To choose the right “nut” depending on the diameter of the wire, you need to use the table.
| Clamp type | Line cross-section mm² | Branch section mm² | Clamp dimensions |
| U731M | 4 – 10 | 1.5 – 10 | 42 x 41 x 31 |
| U733M | 16 – 35 | 1.5 – 10 | 42 x 41 x 31 |
| U734M | 16 – 35 | 16 – 25 | 42 x 41 x 31 |
| U739M | 4 – 10 | 1.5 – 2.5 | 42 x 36 x 23 |
| U859M | 50 – 70 | 4 – 35 | 62 x 61 x 43.5 |
| U870M | 95 – 150 | 16 – 50 | 84 x 85 x 60 |
| U871M | 95 – 150 | 50 – 95 | 84 x 85 x 60 |
| U872M | 95 — 150 | 95 — 120 | 84 x 85 x 60 |
To make the connection, you need to disassemble the carbolite body. It consists of two halves compressed by two retaining rings. If the rings are pryed and removed, the body will fall apart. If the wires are made of different metals, then it is necessary to use an additional plate. It will prevent contact of different metals and further oxidation process, which will worsen the contact. The screws are tightened with reasonable torque and inserted into the housing.
Using a bolt
The bolt connection is most often used when it is necessary to connect copper and aluminum wires. Stripped wires are put on a regular steel bolt, and steel washers and a Grover washer are put between them. The entire “sandwich” is pulled together and wrapped with insulating tape.
What to do if there are several wires?
To connect multiple wires, you can use a terminal block. To do this, you need to connect one half of the contact plates with one wire. The number of such plates must be equal to the number of wires. The remaining wires are attached to the opposite contacts of the plates.
You can take a terminal block with a number of plates equal to the number of wires divided in half. Then one half of the wires is clamped onto one half, and the other half onto the other half of the contacts.
Multiple wires can be connected using a bolt. Place a steel washer between the wires, and put a Grover washer under the nut.
Identical wires can be connected using a PPE cap using known technology or by welding.
What to do if the wires are of different sections?
If you need to connect wires with cores of different sections, you can use:
- Soldering or welding;
- Bolted connection;
- Connection with self-clamping terminals;
- Screw terminals;
- Branch clamp;
- Copper lugs and bolted connection.
Combining stranded and single-core products
The connection of stranded and single-core wires can be made using:
- Solder connection;
- Connection with special sleeves;
- Terminal connections;
- Connection with lugs.
How to carry out work in water and on land?
All outdoor electrical wiring must be carefully protected from moisture. For installation, it is necessary to choose cable products that are designed for such work. The cable must have at least two insulating layers. In addition to the existing insulation, the wire must be placed in a corrugation. For installation in the ground - in a pipe with sealed couplings.
All sockets, switches, lamps and other elements must be manufactured in the appropriate design. On water, only low voltage is used for power supply. All connecting elements are placed above the water level.
Connecting two computers using a cable may be needed in a variety of situations. Using a crossover cable you can working connection between two computers, between two laptops or between a laptop and a computer. In particular, such a connection can be useful for those users who want to transfer large files from one machine to another (for example, a collection of films or music albums).
Using a cable is ideal if you want to connect two computers but do not have special network equipment at hand. If one of the machines has two network cards installed, then you can easily configure Internet access on this machine and on the other. If only one network card is installed on the computers, this will not work.
We will analyze in detail two connection options. In the first case, we will talk about the features of setting up a connection when only one network card is installed on each computer. In the second case, the settings will imply the presence of two network cards on one of the computers (both a regular PC with two cards and a laptop with one regular network adapter and the second wireless).
What is needed to connect two computers
We do not need any special network equipment to cable connect computers. You can carry out all operations yourself using a minimal set of components.
We will need:
- Actually two computers
- Cross cable
- Perseverance and a little patience
A crossover cable can be easily purchased at any electronics store or radio market. Also, if you wish, you can prepare such a cable yourself, but this will undoubtedly be more difficult and longer. The crossover cable pinout is shown below.
The finished cable that will be used to connect computers is shown below.
This option is used most often, since few computers (especially PCs) have two network cards installed. In most cases home computer equipped with one network card. With this type of connection, both machines will not have access to the Internet. The general connection diagram is shown in the photo below.
After a physical cable connection between two computers, you need to carry out simple network settings. We will analyze the entire setup process in detail so that you do not have any questions.
To get started, go to the Network and Sharing Center and click on the “Change adapter settings” link.
After that, double-click on the cable network connection.
Click on “Properties”.
We install selectors opposite the manual setting of network parameters and enter the values there as in the photo below.
Click “Ok” and “Apply”. On the second computer, the sequence of actions is similar, but in the IP address field we enter the value “192.168.0.2”. After these simple settings, a working connection will be established between the two computers.
To check the functionality of the created network on a second PC, press the key combination “Win + R” and enter the command “cmd”.
In the window that appears, enter the command “ping 192.168.0.1”. In response, a message should appear indicating the successful transmission of packets.
The same can be done on the first computer, just use the command “ping 192.168.0.2”. If you are unable to ping the network, it means you did something wrong or the connection is blocked by an antivirus or firewall.
Now let’s take a closer look at the option of how to connect two computers with a cable so that each computer can access the Internet. To do this, one of the machines must have two network cards installed: one for connecting to another computer, the second for connecting the provider’s cable. The general connection diagram is shown in the photo below.
The network settings are the same as those we looked at in the first method, with the exception of one point. In addition to the IP address and mask, you will also need to set the gateway.
On a computer with two network cards, you need to configure network access to the Internet, so that on the first computer you can freely use the Internet. To do this, on a computer with the address 192.168.0.1, go to the “Access” tab and check the box next to the corresponding inscription. After this, both computers will be able to access the Internet.
conclusions
We found out how you can connect two computers using a crossover cable and how to correct setting connections for normal operation networks. We really hope that this information will help you solve the problem of connecting two computers quickly and efficiently.
So, let's get started. We have at our disposal two computers or laptops, it doesn’t matter, and a router connected to the Internet. We need these two computers to exchange information with each other via a local network. I want to say right away that it doesn’t matter how these two computers will connect to the router: via cable or via Wi-fi. The main thing is to make the following settings. Everything described below is performed on two computers:
1. We give our computers different names and assign them to the same workgroup. To do this, click the “Start” button and right-click on “Computer” and select “Properties”
In the tab "Computer name" click on the “Change” button
In the next window, change the computer name and, if necessary, working group (The workgroup of the two computers must be the same, but the names must be different.).
2. Right-click on the network status icon and select
Click on the left “Change” Extra options public access":
We enable sharing and network discovery, as shown in the screenshot:
We also disable password protected sharing. If this is not done, then only computers with Windows OS that have a password will be able to connect to such a network (how to set a password on Windows)
3. Go to again "Network and Sharing Center" and click on the item on the right side "Change adapter settings":
Select our connection to the router. This can be either a connection via local network via cable or wireless network connection. Right-click on it and select “Properties”.
Finding the component "Internet Protocol Version 4", select it and click on the “Properties” button.
We put the switch in position "Obtain an IP address automatically". Click "OK".
All information on one computer cannot be accessed on another. You need to share certain folders on both computers so that you can exchange information using those folders. To do this, right-click on the selected folder and select "Shared Access - Specific Users".
We click on the one we need from two computers and see that all our shared folders are available for viewing and editing:
We succeeded connect two computers together.

Electricity is not an area where you need to save. It is advisable to do everything carefully, select high-quality materials, and take a balanced approach to the choice of sizes/diameters/values. Let's start with the fact that even the conductors must be connected correctly. And choosing ways to connect wires is not as easy as it seems.
There are about a dozen ways to connect wires. In general, they can be divided into two groups: those that require special equipment or specific skills and those that can be successfully used by any home craftsman - they do not require any special skills.
The first group includes:
- Soldering. When connecting wires of small diameter in the amount of 2-3 pieces, this is a very reliable method. True, it requires a soldering iron and some skills in using it.
- Welding. You need a welding machine and special electrodes. But the contact is reliable - the conductors are fused into a monolith.
- Crimping with sleeves. You need sleeves and special pliers. The sleeves are selected according to certain rules that you need to know. The connection is reliable, but it will have to be cut to re-seal.
All these methods of connecting wires are performed mainly by specialists. If you have skills with a soldering iron or welding machine After practicing on unnecessary scraps, you can make them yourself.
Some methods of connecting wires are more popular, others less so.
Methods of connecting wires that do not require any specific skills are becoming increasingly popular. Their advantage is quick installation and reliable connection. Disadvantage - you need “connectors” - terminal blocks, clamps, bolts. Some of them cost quite a lot of money (Wago terminal blocks, for example), although there are also inexpensive options - screw terminal blocks.
So here are ways to connect wires that are easy to implement:
There are two opposing opinions among professionals. Some believe that new methods of connecting wires - clamps - are the best solution, as they speed up installation without compromising the quality of the connection. Others say that the springs will eventually weaken and contact will deteriorate. In this matter, the choice is yours.
Technical nuances of different types of wire connections
All types of wire connections described above are used when laying electrical wiring, but the specific type is selected based on several characteristics:
Let's consider each connection method, the technology for its implementation and the advisability of use in various situations.
Soldering electrical wires
One of the oldest and most widespread types of connection. To work you will need rosin, solder and a soldering iron. The soldering process is as follows:
Actually, this completes the soldering of electrical wires. Not the best difficult process but requires certain skills. The main thing is to heat the joint enough so that the solder flows between all the wires. In this case, you must not overheat, otherwise the insulation will melt. This is where the art lies - not to burn the insulation, but to ensure reliable contact.
When can soldering be used? This method of connecting wires works well in low-current electrical applications. When connecting wires in a junction box, it is no longer very convenient. Especially if there are a lot of wires and/or they are of large diameter. Soldering such a twist is not a task for beginners. In addition, when trying to make a connection in a junction box, the soldering begins to break down. To the point where some wires fall off. In general, the method is good for connecting conductors of small diameters.
Welding conductors in electrical connections
One of the most reliable methods of connecting wires is welding. During this process, the metal of individual conductors is brought to the melting point, mixed, and after cooling it forms a monolith. This method works very well with large diameters or with a large number of connected conductors. It is distinguished by not just excellent contact, which does not weaken or change its characteristics over time. It is also mechanically very strong - the fused part does not allow the connection to fall apart even under heavy loads.
A drop at the end of the twist is molten aluminum
There are also disadvantages. The first is that the conductors are fused, that is, the connection is absolutely permanent. If you need to re-seal it, you have to remove the fused part and start all over again. To be able to do this, you must always leave a small gap along the length of the wires. The second drawback is that you need a welding machine, skills in handling it, and special electrodes for welding aluminum or copper. The main task in this case is not to burn the insulation, but to melt the conductors. To make this possible, they are stripped of about 10 cm of insulation, tightly twisted into a bundle, and then welded at the very end.
Another disadvantage of welding wires is that it is a labor-intensive process, which also requires pinpoint precision in handling the welding machine. Due to the combination of these qualities, many professional electricians do not like this method. If you do the wiring “for yourself” and know how to handle the equipment, you can spend some time. Just practice first on scraps, select the current strength and welding time. Only after you get everything perfect several times can you start welding wires “in real life”.
Crimping
Another method that requires special equipment is crimping wires with sleeves. There are copper and aluminum sleeves of different diameters. The material is selected depending on the material of the conductor, and the size is selected according to the diameter and number of wires in a particular connection. They should fill almost the entire space inside the sleeve, but there should still be free space. The quality of contact depends on the correct choice of sleeve size. This is the main difficulty with this method of connecting wires: the sleeve should not be too large or too small.
The technology of work is as follows:
- The conductors are stripped of insulation (the length of the stripped section is slightly longer than the length of the sleeve).
- Each conductor is stripped to bare metal (we remove oxides with fine-grain sandpaper).
- The wires are twisted and inserted into the sleeve.
- They are crimped with special pliers.
It seems to be simple, but it is in the selection of the sleeve and the presence of pliers that the whole difficulty lies. You can, of course, try to crimp it with pliers or pliers. But it is impossible to guarantee normal contact in this case.
Twist
In the first section of the article, we deliberately omitted twisting the wires. According to the current standard, it cannot be used, since it does not provide proper contact and reliability of the connection. This method can replace any other methods of connecting wires.
Yes, wiring was done on twists 20-30 years ago and everything worked perfectly. But what were the loads on the networks then, and what are they now... Today, the amount of equipment in an ordinary apartment or private house has increased significantly, and most of the equipment is demanding on power supply. Some types simply will not work at reduced voltage.
Why is twisting so bad? Wires twisted into a bundle do not provide enough good contact. At first, everything is fine, but over time the metal becomes covered with an oxide film, which significantly worsens the contact. If there is insufficient contact, the joint begins to heat up; an increase in temperature causes more active formation of an oxide film, which further worsens the contact. At some point, the twist becomes very hot, which can lead to a fire. It is for this reason that it is better to choose any other method. There are some that can be done even faster and easier, but which are more reliable.
Connection insulation
All the methods of connecting wires described above - welding, soldering, crimping with a sleeve - provide for their insulation, since the exposed conductors must be protected. For these purposes, electrical tape or heat-shrinkable tubes are used.
Everyone probably knows how to use electrical tape, but we’ll tell you a little about heat-shrinkable tubes. This is a hollow polymer tube, which, with increasing temperature, significantly reduces its diameter (2-6 times, depending on the type). The size is selected so that the pre-shrink volume is larger than the diameter of the insulated wires, and the post-shrink volume is smaller. In this case, a tight fit of the polymer is ensured, which guarantees a good degree of insulation.
Heat-shrinkable tubes for insulating conductors can be of different diameters and colors
In addition to size, heat shrink tubes are selected according to special characteristics. They are:
- heat resistant;
- light-stabilized (for outdoor use);
- oil-gasoline resistant;
- resistant to chemicals.
The cost of heat-shrinkable tubes is not very high - from $0.5 to $0.75 per 1 meter. Their length should be slightly longer than the length of the bare conductors - so that one edge of the tube stretches over the insulation of the conductors by about 0.5 cm, and the other sticks out by 0.5-1 cm. After the tube is stretched, take a heat source (you can use a lighter) and heat the tube. The heating temperature can be different - from 60°C to +120°C. After the joint is tightened, the heating stops, after which the polymer quickly cools.
Insulating wires with heat-shrinkable tubing takes little time—seconds count—and the quality of the insulation is high. Sometimes, for greater reliability, two tubes can be used - a slightly smaller and a slightly larger diameter. In this case, first one tube is put on and warmed up, then the second. Such connections can be used even in water.
Terminal blocks
This method is also preferred by electricians, but can be easily used by a person who can hold a regular screwdriver. This is one of the first ways to connect electrical wires without soldering. Today, on almost every electrical appliance you can see a version of this connection - this is the output block to which the power cord is connected.
Terminal blocks are a contact plate that is sealed in a plastic (polymer) or carbolite housing. They cost very little and are available in almost any store that sells electrical goods.
Terminal blocks are convenient, inexpensive, allow you to connect copper and aluminum wires, conductors of different diameters, single- and multi-core
The connection occurs literally in seconds. The insulation is removed from the conductor (approximately 0.5-0.7 cm), and the oxide film is removed. Two conductors are inserted into the socket - one opposite the other - and secured with bolts. These bolts press the metal against the contact plate, making the connection.
The advantage of this connection method: you can connect wires of different sections, single-core to multi-core. The disadvantage is that only a pair of wires are connected. To connect three or more, jumpers must be installed.
PPE caps
Another way to connect wires that does not require special skills is to install PPE caps. They are a plastic cone-shaped body with a spring sealed inside. They happen different sizes- from 0 to 5. You can connect wires of different diameters - on each package the minimum and maximum and minimum total cross-section of the wires to be connected is written. In addition, there are cases simply in the form of a cone, and some with stops “ears” that make their installation easier. When choosing, pay attention to the quality of the plastic - it should not bend.
Connecting wires using PPE is very simple: strip the insulation, collect the wires into a bundle, insert them inside the cap and start twisting. A spring inside the cap grips the conductors, helping to twist them. The result is a twist, which is wrapped around the outside with spring wire. That is, the contact turns out to be very high quality and good. This method of connecting wires with PPE caps has been used for a long time in Europe and America; it came to us about 10 years ago.
If you need ways to connect wires without welding, consider PPE
There is another way: first the wires are twisted, then caps are put on them. This method was invented by the Russian company that produces these wire connectors - KZT. But this technique requires more time, and the quality of the connection is no different.
There is one more point: how long to strip the insulation from the wires. Manufacturers give clear instructions on this matter - each size has its own length of exposed conductors. It is designed so that all conductors without insulation are inside the housing. If you do this, the connection does not require additional insulation, which greatly speeds up the process. In addition, the expanded lower part does not interfere with heat dissipation and such a connection heats up less.
Practicing electricians advise stripping the wires by 5-10 cm, and insulating the twist that remains without insulation. This is argued by the fact that the contact area with this option is larger. It is true, but this option heats up more. And the standard solution is reliable. There are no problems with contact (if the quality of PPE is normal).
Wago Clamps
The heated debates flared up specifically about Vago. Some people absolutely love this product, while others don’t. Moreover, no less categorically. Opponents of using the Wago don't like the fact that the contact is based on a spring. They say that it may weaken. This will lead to poor contact and overheating. And they show a photo with melted clamps. Proponents of this method conduct tests and comparisons and say that a properly selected branded clamp lasts for many years without signs of contact deterioration. And manufacturers say that, if the technology is followed, Wago terminal blocks can be used for 25-35 years. It is important to choose the right type and parameters and not buy a fake (there are a lot of them).
There are two types of Vago clamps. The first series is slightly less expensive, called Wago. These clamps are suitable for connecting single-core and stranded wires with a cross-section of 0.5-4 mm2. For conductors of smaller or larger cross-sections there is another series - Cage Clamp. It has a very wide range of use - 0.08-35 mm2, but also high cost. In any case, contact is ensured by a contact plate made of good copper. The special shape of the plate allows for reliable contact.
Detachable
In addition, Vago spring-loaded clamps are detachable (222 series) and permanent (773 and 273 series). Detachable ones are convenient to install in places where changes to the network configuration are possible. For example, in distribution boxes. They have levers with which the wires are clamped or released. Wago detachable terminal blocks can connect from 2 to 5 conductors. Moreover, they can be of different sections and types (single-core and multi-core). The order of connecting the wires is as follows:
We repeat the same operation with the other wire(s). All this takes a matter of seconds. Very fast and convenient. It's not surprising that many professional electricians have forgotten other ways to connect wires.
One-piece
One-piece series differ in structure: there is a clamp body and a cap. The cap can be made of transparent polymer (773 series) or opaque plastic (223). The housing has holes into which wires stripped of insulation are inserted.
To ensure normal contact, you just need to remove the insulation correctly - exactly 12-13 mm. These are the requirements set by the manufacturer. After the conductor is inserted, its bare part should be in the terminal block, and the insulation should rest against the housing. Under such conditions, contact will be reliable.
Bolted connection
Another type of connection of electrical wires with solid experience is bolted. It is called so because a bolt, nut and several washers are used to connect the wires. Contact through the use of washers is quite good, but the entire structure takes up a lot of space and is inconvenient to install. It is mainly used if it is necessary to connect conductors made of different metals - aluminum and copper.
The order of assembling the connection is as follows:
- We strip the wires of insulation.
- From the stripped part we form a loop, the diameter of which is equal to the diameter of the bolt.
- We put it on the bolt in this order
- washer (it rests on the bolt head);
- one of the conductors;
- another washer;
- second conductor;
- third washer;
- We tighten everything with a nut.
This way you can connect not only two, but also three or more wires. Please note that you must not only tighten the nut by hand. You have to use wrenches and put in a lot of effort.
The best ways to connect wires for different occasions
Since they can connect different wires, they can be used in different conditions, then the optimal method must be chosen taking into account all these nuances. Here are the most common situations:
These are the most common options for non-standard connections.
In the previous article we talked about how to make a network cable (patch cord) with your own hands. Let’s say you’re lucky enough to become the owner of not one, but two computers, and then, as luck would have it, a new problem, which did not exist before purchasing a new computer: there was a need to connect two computers to each other.
What is it for? Well, for example, if you need to move files from one computer to another, so as not to run around with a flash drive between them (and if the files are large and there are a lot of them, but the flash drive is modest), you can create a shared folder on one of the computers and put everything you need there. You can also use one printer and print to it from any computer. And most importantly, you can use one Internet connection on two computers.
In short, there are many advantages, but there is only one drawback - the network cards in computers will be busy, and if a modem for accessing the Internet is connected via a LAN connector, that is, to a network card, then in order to connect two computers to each other, one of them needs will deliver another one network card. If the modem is connected to the computer via a USB connector, then there is no need to deliver anything.
So how do you connect two computers to each other? All actions were carried out on Windows 7 and Vista, but the main thing here is to know the procedure, and it can be repeated on any OS. We turn on two computers and connect them with a network cable. Next, open My Computer on one of them, right-click on any empty area, select Properties. Next we find ourselves in the System window. In this window, click on the button Change settings, next to the computer name.
Here we are on the tab Properties of the system, where we are interested in the Change button, click it. After we clicked the Change button, a window appears Changing the computer name or domain. In the “working group” line, you need to check the box and write the name of the working group that you are creating.
