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 the DC power is transmitted to the electrical equipment through the contact of the contact piece and the spring piece. the DC socket usually has a high current capacity, and it can meet the power demand of different kinds of equipments.

Classification of DC socket

　　DC sockets can be categorized into different types according to different classifications. According to the shape, DC sockets can be categorized into straight plug type and side plug type. The straight plug socket plug is parallel to the socket and is suitable for equipment installed horizontally; the side plug socket plug is perpendicular to the socket and is suitable for equipment installed vertically. According to the number of interfaces, DC sockets can be divided into single-port and multi-port. Single-port sockets have only one interface and are suitable for simple power connections; multi-port sockets have multiple interfaces and are suitable for power connections of multiple devices. According to the voltage level, DC sockets can be categorized into high voltage and low voltage. High-voltage sockets are suitable for high-voltage power environments, and low-voltage sockets are suitable for low-voltage power environments.

Specification of DC socket

　　With the progress of society, the market for dc socket demand is increasing, then how to connect the dc socket pin? dc socket different specifications of its dc socket pin wiring is different, the common dc socket specifications are: 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm, and so on. In the process of using dc socket must pay attention to the protection of dc socket pins, in the dc socket pins packaging must be scientific and reasonable, to avoid dc socket pins deformation, loosening, tilting, scratches, must not have bad plating, oxidation and rust and other phenomena, affecting its normal use.

DC socket purchase

(1) Choose regular brand products: When buying DC power socket, you should choose regular brand products and avoid buying unlicensed products. Products of regular brands usually have higher safety and reliability.

(2) Choose the type of socket according to the needs of the device: Different devices may require different types of DC power sockets, such as USB sockets, HDMI sockets, RCA sockets and so on. Therefore, when purchasing sockets, you should

choose the corresponding type of socket according to the interface requirements of the device.

(3) Pay attention to the rated voltage and current of the socket: When choosing DC power sockets, you should pay attention to the rated voltage and current of the sockets to ensure that the sockets can meet the power supply needs of the devices.

(4) Choose high-quality sockets: Choosing high-quality DC power sockets can ensure the safe and stable operation of the equipment. High-quality sockets are usually made of high-quality materials, such as tin phosphor-cyanide copper and materials with good flame retardancy.

(5) Pay attention to the size and installation of the socket: When choosing DC power sockets, you should pay attention to the size and installation of the socket to ensure that the socket can adapt to the installation and use requirements of the equipment.

(6) Consider environmental protection and safety performance: When purchasing DC power sockets, you should choose products with environmental protection and safety performance to protect the environment and human health.

(7) Check the appearance and packaging of the sockets: When purchasing DC power sockets, you should check the appearance and packaging of the sockets to ensure the quality and safety of the sockets.
