　　DC socket is a special type of socket suitable for DC power supply, that is, DC power supply. It is usually used for power input and signal transmission in electronic devices, appliances, instruments, and other equipment. The sockets and pins of DC sockets are specially designed to be used in conjunction with DC power plugs to achieve reliable power connections and signal transmission.
　　The structure of a DC socket generally consists of two parts, one is the socket body and the other is the plug. The socket body is a part fixed to the DC electrical appliance, which has a central hole and an outer ring. The central hole is used to receive the central pin of the plug, and the outer ring is used to contact the housing of the plug. A plug is the part connected to a DC power line, which has a center pin and a housing. The center pin is used to insert into the center hole of the socket, and the housing is used to fit the outer ring of the socket. When the plug and socket are fully connected, a closed circuit is formed, which enables the transmission of electrical energy between the DC power supply and DC appliances.

　　There are many types of DC sockets that can be classified according to different standards. For example, according to the installation method of the socket body, it can be divided into patch type, direct insertion type, sinking plate type, etc; According to the diameter of the central needle, it can be divided into 0.5mm, 0.7mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm, etc; According to the rated current, it can be divided into 0.5A, 1A, 2A, 3A, 5A, etc; According to the rated voltage, it can be divided into 3V, 5V, 9V, 12V, 15V, 24V, etc; According to the number of terminals, it can be divided into 2P, 3P, 4P, 5P, etc; According to the shape of the contacts, they can be divided into round headed contacts and triangular contacts.
　　DC sockets are widely used in various electronic devices, such as communication devices, household appliances, industrial control equipment, etc. They provide stable and reliable DC power supply for these devices, ensuring their normal operation.
　　DC sockets play a crucial role as the cornerstone of stable operation of electronic devices. With the advancement of technology and the increasing demand for applications, DC sockets will continue to develop and innovate, providing more stable, reliable, and efficient power support for the stable operation of electronic devices.
