DC socket is a kind of interface that connects battery or power supply with electrical equipment through wires to realize the transmission of direct current. It consists of two parts, the plug and the socket. the plug is inserted into the socket, and through the contact of the contact piece and the spring piece, the DC power is transmitted to the electrical equipment. the DC socket usually has a high current capacity, and it can meet the power demand of various different equipments.

Positive and negative poles of DC sockets

The positive and negative poles of DC sockets are usually determined by the structure of the socket, in which the cylindrical, thinner part of the pins in the center is the positive pin, while the circular, thicker part of the pins on the outer edge is the negative pin.

This design ensures that the positive and negative pins correspond correctly when the plug is inserted into the socket. The positive terminal is the output of the current, providing DC power to the connected device, while the negative terminal is used to connect the return path of the current, completing the circuit loop. Correct connection of the positive and negative terminals is critical to the proper operation of the device. In addition, some DC sockets may have a reverse connection protection mechanism to avoid misconnection of the power supply. When the positive and negative terminals of the plug are connected in the wrong way, the socket will automatically disconnect the circuit, preventing the flow of current and thus preventing damage to the circuit and equipment.
