How do I connect the lines? How to connect the line?

Internal line connection method of computer host: This type of equipment needs two types of wiring to work normally: one is an 80-pin data cable (the optical drive can be 40-pin), and the other is a 4-pin power cable.

When connecting, first insert one end of the blue plug of the data cable into the IDE port on the motherboard, and then plug the other end into the hard disk or optical drive port. Then plug the power cord connector into the power connector of the IDE device.

Power connection: 20 core power connection: The motherboard is powered by it. Pinch the plastic clip on the power connector firmly, and then plug the power connector straight into the 20-pin power socket next to the CPU socket of the motherboard. Note that the card is in the same direction as the card holder.

CPU power connection: Due to the huge power consumption of the CPU at the P4 level, the system also needs to supply power to the CPU separately, so a 4-pin power socket is provided near the CPU, and a square four-pin power plug at the power output end is aligned with the card socket when connected.

4-pin power cable: In addition to connecting to ordinary IDE devices, the 4-pin power plug can also be used to supply power to the case fan or graphics card.

CPU Fan Cable: After installing a heatsink for the CPU, plug the power input of the cooler (dark red) into the "CPU Fan" near the CPU on the motherboard.

This connection line needs your professionals, which we don't usually understand.

Thread generation is now more fool-proof. You can plug it in. But the line on the hard disk. The yellow line is at the outer end. There is a 1234 logo on the power cord.

The best way is to check the motherboard manual, which is very detailed, and how to connect it will tell you! If the manual is gone, then there is another way to look at the logo on the motherboard, which will be available on the main version in general, as long as you pay attention to the front panel control signal line.

I don't know how to tell you about this.

Hard drives, these lines are easy to say. The plug is on the right line. Jumper those. You'd better take it to the computer city.

1. It all depends on whether you connect the network cable or the wire. The network cable should be connected with a crystal head, which needs to be done in accordance with the standard, and one end is connected to the cat or router after it is done, and the other end is connected to the computer. If the wire is connected to the switch at home, you only need to connect the live wire head in the wall to the live wire port of the switch, and the zero wire is connected to the zero wire of the switch.

The letter symbol for the line of fire is l, and the letter symbol for the line of zero is n

The switch of the lamp only passes through the live wire, and the zero line does not need to go to the switch. Don't connect the wrong order of the live wire, otherwise the lights will always be lit.

There is no inevitable relationship between the wire plug and the lamp, just go in as soon as you fire and zero.

I am a weak current worker, the above is experience, if there is something wrong, I hope to correct it.

It's simple, and it's connected. It is to control the two wires on a light bulb controlled by your switch, one wire to the bottom line, connected to the bulb, according to this method to connect as many as you want, but it depends on the power of the bulb, to see if the switch can afford it, if the power is too large, the switch will use a larger power (such as 10a, 50a, 100a, etc.).

As long as the same line is connected, it can be used.

Connect the live wire post of the electrical appliance to the zero wire of the live wire and connect the zero terminal to the zero wire.

What kind of line to take? I didn't make it clear!

The line is divided into red for the live wire, blue for the neutral wire, and yellow for the ground wire.

What line do you refer to, whether it is a strong or weak line, can you explain the white point or send a circuit diagram?

I didn't see your **, if there is**, I will tell you how to pick it up, I am a professional electrician, and general incurable diseases can be handled.

Oh ** room waited for a long time, suddenly people and things.

How to connect this line? Pick up the line, I need to find a repairman.

How do you remember these roads? You don't have a **, nothing, just ask how to pick it up, you are an electrician who can generally see it. Anywhere there is a problem, it can be dealt with.

It's not that the electrician doesn't understand this. In reality, there are many times in the Czech route. Can you limit how to connect?

You have to find the electrician who works the job, he understands how to connect the line, what line are you connected to the wire? It's Deng, what is it? Pick you up and go to him, how did he end it?

He knew he understood as soon as he looked at him. You ask us that we are not electricians, we don't understand anything, and we don't know how to connect. Nowadays, there are many professional electricians, who can deal with it directly when they see where there is a problem.

This specific line is very troublesome and troublesome in reality. Can't find the cause of the problem? If you find something wrong, you can deal with it on the spot and fix it.

Hello, I recommend that you consult your physics teacher, who is very good at this aspect.

It depends on what the specific route is? In reality, when connecting lines, it is often limited by the space.

First of all, get to know the five-pin socket with switch.

The inside of the five-pin socket has been wired, as long as the corresponding power supply is connected. There are five binding posts on the back of the socket, which are marked with L, N, E, L1, L11, live wire, N zero wire, E ground wire, and other connections are different according to the use of the socket.

The purpose of the five-pin socket with switch can actually be divided into three situations:

a. Switch control socket.

b. Switch control single control switch.

c. Switch control dual control switch.

Wiring diagram of the switch control socket.

Wiring diagram of a switch-controlled single-control switch.

The switch controls the dual-control switch, and the switch needs to be matched with the dual-control switch.

A wire is a wire that transmits electrical energy. It is divided into bare wire, magnet wire and insulated wire. Bare wires are not insulated, including copper and aluminum flat wires, overhead stranded wires, and various profiles.

Please tell me clearly which lines they are, there are many lines, such as circuits digging rails, everything.

I don't, understand, I want to connect which red to red color unchanged three-hole socket below the L a live wire, n a zero, the upper hole a protection line,

1. There are two wiring methods for the installation of three-phase watt-hour meters. One is to use a circuit transformer to connect with the watt-hour meter. The other is a direct wiring intake meter.

2. Here is an explanation about direct wiring. The first thing to do is to buy a direct wiring watt-hour meter.

3. Install a screw on the wall or on the installation screw post of the watt-hour meter. Then open the wiring cover of the watt-hour meter. Generally, there is an installation wiring diagram on the back of the cover. , 4, 7 is the power incoming line. There is no need to distinguish the ABC three-phase here, but it must be 3 live wires, that is, 3 phase wires.

5. Then install the 3 phase wires in the wiring hole. Be careful to make good contact, that is, tighten the 2 screws.

6. Then connect the line again. If the outgoing wire is a multi-strand copper wire, it must be twisted into a single wire and there can be no forked wire.

7. Finally, connect the zero line to the zero line of the watt-hour meter.

1. Direct access method:

If the power of the load is within the allowable range of the watt-hour meter, i.e., the current flowing through the watt-hour meter current coil will not cause the coil to burn out, then the direct access method is used. The single-phase watt-hour meter has a total of four terminal blocks, numbered from left to right.

There are generally two kinds of wiring, which are generally incoming and outgoing wires; The other is to press the incoming line to connect the outgoing line. Regardless of the connection method, the phase wire (live wire) must be connected to the terminal of the current coil of the meter. Due to the special wiring of some meters, the specific wiring method needs to refer to the wiring diagram on the terminal block to connect.

2. Mutual transformer access method:

When measuring the electricity consumption of a single-phase circuit with a single-phase watt-hour meter with a large current, a current transformer should be used for current conversion, and the current transformer should be connected to the current coil of the watt-hour meter. There are two ways to connect:

1) The connection method when the 5th and 1st ends of the single-phase watt-hour meter are not disconnected. Since the short connector in the table is not disconnected, the K2 terminal of the transformer is forbidden to be grounded.

2) The connection method when the short connector at the 5th and 1st ends of the single-phase watt-hour meter has been disconnected. Since the short tab in the table is disconnected, the K2 terminal of the transformer should be grounded. At the same time, the voltage coils should be connected to both ends of the power supply.

3. Turn over the terminal cover, and you can see the wiring diagram of the three-phase four-wire meter. Wherein connect the S2 end of the secondary side of the current transformer, that is, the current inlet terminal is connected to the S1 end of the secondary side of the current transformer, and the current outlet end is connected to the three-phase power supply respectively;

It is connected to the zero end. For safety, the S2 end of the current transformer should be connected to ground after being connected. It should be noted that the current measurement sampling of each current transformer must be in phase with its voltage sampling, i.e. as a group for a group and as a group.

1. In order to adapt to the use of smart grid and new energy, smart meters also have two-way multi-rate metering functions, user-end control functions, two-way data communication functions of multiple data transmission modes, anti-theft functions and other intelligent functions.

2. For the wiring method of its control line, the wiring method of the general domestic single-phase electric energy meter, regardless of its model, if there is no special orderer, the wiring method is the same.

3. The specific wiring method of the single-phase smart electric energy meter is to open the junction box cover, and you can see four large terminals.

4. These four terminals are easy to find, because other terminals such as centralized reading interface, pulse output, communication interface and so on are very small.

5. From left to right, press 1, 2, 3, 4 to number, then the general wiring method is 1, 3 incoming; 2,4 out of line.

I haven't used the model you mentioned, but the basic approach is that you only recognize the 4 largest holes. (Other small holes, it is indeed a variety of signal wires, you can ignore him).

The installation method of the 4 large holes is:

1 connection to the incoming line of the live wire, 2 connected to the outgoing line of the live wire, 3 connected to the incoming line of the zero line, 4 connected to the outgoing line of the zero line, after the installation, turn on the load larger, the small light on the meter, should be flashing

As shown in Figure 1, the incoming line of the live wire, 2, the outgoing line of the live wire, 3, the incoming line of the zero line, 4, the outgoing line of the zero line, 5 and 6 are connected to the pulse, you can read the meter remotely, you don't have to worry about this, it is connected by the power supply bureau itself.

You'd better find a professional electrician!

That's more certain! ~
