DC sockets can be classified into different types according to different classification methods. According to the shape, DC sockets can be divided into two types: direct insertion and side insertion. Direct insertion socket plug is parallel to the socket, suitable for horizontally installed equipment; The side plug-in socket plug is perpendicular to the socket and is suitable for vertically installed equipment. According to the number of interfaces, DC sockets can be divided into two types: single port and multi port. Single port socket only has one interface, suitable for simple power connection; A multi port socket has multiple interfaces and is suitable for power connection of multiple devices. According to voltage level, DC sockets can be divided into two types: high voltage and low voltage. High voltage sockets are suitable for high voltage power environments, while low voltage sockets are suitable for low voltage power environments.
Specifications of DC sockets
With the progress of society, the demand for DC sockets in the market continues to increase. So, how to connect the pins of DC sockets? Different specifications of DC sockets have different wiring methods for their DC socket pins. Common DC socket specifications include 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm, etc. During the use of DC sockets, it is necessary to pay attention to the protection of DC socket pins. The packaging of DC socket pins must be scientifically and reasonably designed to avoid deformation, looseness, tilting, scratches, poor electroplating, oxidation and rust, which may affect their normal use.

The characteristics of DC sockets
1. Energy conservation and environmental protection: DC sockets directly supply direct current, reducing energy conversion losses, improving energy utilization efficiency, and reducing environmental impact.
2. Safe and reliable: DC sockets are powered by direct current, which is not easy to generate arcs and electromagnetic radiation, reducing the risk of fire and electromagnetic radiation, and improving the safety of the power supply system.
3. Strong adaptability: DC sockets can be freely combined and expanded according to different power requirements, adapting to different application scenarios and needs.

Precautions for using DC power sockets
1. Before use, check if the markings on the DC power socket are complete, including the power supply nature symbol, rated current value, and relevant warning messages.
2. DC sockets should be used with devices that match their rated current value. Do not plug high-power household devices into DC power sockets with lower rated current values.
3. DC power sockets must never come into contact with water, as internal circuits may experience short circuits or other phenomena when in contact with water.
If a malfunction is found in the DC socket during use, do not disassemble and repair it yourself. Due to the complex wiring of DC power sockets, if not taken seriously, there is a high possibility of safety accidents. Therefore, professional technicians should be invited to repair or replace them.
