Speaking of DC socket, many people only think of the socket and ignore the DC. We can directly see the socket, such as bull socket, while DC socket is only an electronic component with relatively small volume. It is also called DC power socket, which is equivalent to a connector. DC sockets are not only classified in a variety of ways, but also widely used. It is mainly used for electronic and other related products. With the continuous development and progress of science and technology, people will design various convenient things one by one on the functions not available in many products in the past. For example, in the past, cars were very old-fashioned manual gears, and there was no navigator at all. Now, there are not only many other comfortable devices.

How does the DC socket work? First of all, we need to understand the principle of DC power socket connection. When the plug is inserted, the moving contact pin inside the power socket will be pushed open, so as to cut off the negative path of the battery inside the circuit. At this time, after the power socket coil is powered on, the iron core in the coil will generate strong electromagnetic force, suck the armature to drive the internal reed to disconnect contacts 1 and 2. At this time, pins 1 and 3 are connected to the power supply path. The wiring of DC power socket is based on the saying that the left zero and the right fire are connected to the ground, which means that the pin of the power socket is connected to the zero line on the left, the pin on the right is connected to the fire line, and the bow pin grounding wire in the middle (upper).
