Connection Procedure For DC Power Outlet

When connecting the dc power socket, the first thing to consider is the circuit situation. At present, most of the circuits are mainly composed of NPN polar components. The circuit uses the negative pole of the power supply as the common ground, so the DC interface of these electrical equipment The negative terminal is the ground terminal, so the power plug's

The jacket should be connected to the negative terminal of the power supply.

The DC power socket mainly includes a plug terminal, a shell and a plastic body, which is an improved DC power socket. One side of the plug-in terminal set in the socket body is cut into a plane body that can prevent the plug-in terminal from rotating. The plane body is fixed with the plane body on the opposite side of the plastic body. The plug-in terminal is provided with grooves around it. The grooves on the side of the fork are embedded in the grooves to be combined with each other, the socket body is provided with the shell, and the two sides of the shell are provided with clips. There is a groove in the plastic body, and a conductive terminal and a conductive elastic sheet are embedded in the groove. When the power connector pushes the conductive elastic sheet, the conductive elastic sheet contacts the conductive terminal; it has the function of opening and closing to achieve the purpose of stability and stability. Good electrical conductivity and safety effect, and practical.

When connecting, first consider the circuit conditions. Most of the current circuits are the main circuit with NPN polar components as the main circuit. The circuit uses the negative pole of the power supply as the common ground. Therefore, the DC interface of these electrical equipment is negative. It is extremely grounded, so the jacket of the power plug should be connected to the negative terminal of the power supply.

Step 1. Use a test pen to find the live wire and turn off the DC power socket;

Step 2. Connect the live wire to one of the 2 holes of the switch, and then connect a 2.5MM2 insulated wire from the other hole and connect it to the L hole of the 3 holes of the socket below;

Step 3. Find out the zero line directly connected to the N hole of the 3 holes of the socket and connect it firmly;

Step 4. Find the ground wire and connect it directly to the E hole of the 3 holes of the socket;

Due to the special characteristics of the circuit, the DC interface of individual electrical equipment is opposite, so the polarity of the DC plug cannot be arbitrarily determined. If it is not the original power supply, you must first find out whether the polarity of the plug and the polarity of the electrical socket are matched correctly. . The above are the precautions for the connection of DC power sockets summarized by Taiwei Electronics and hope to be adopted.
