A DC socket is an interface that connects a battery or power supply to electrical equipment through wires, achieving the transmission of direct current. It consists of two parts: a plug and a socket. The plug is inserted into the socket and transmits direct current to the electrical equipment through the contact between the contact piece and the spring piece. DC sockets usually have high current capacity and can meet the power needs of various devices.
Specifications of DC sockets
Due to differences in the use of DC sockets depending on computer models, there are many specifications for DC sockets. The center pins of DC sockets include 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, and 3.0mm. Common DC socket specifications include: 2.35 * 0.7TVdc plug, 3.0 * 0.1TV dc plug, 2.5 * 0.75TVdc plug, 3.5 * 1.1TVDC plug, 3.2 * 0.9TV dc plug, 4.0 * 0.7TVdc plug, 4.75 * 1.7TVdc plug, 3.5 * 1.35TV, 2.0 * 0.6TVdc plug, 5.5 * 2.1TVdc plug, 6.5 * 3.0TVdc plug, and 5.5 * 2.5TVdc plug.
Application of DC sockets
DC sockets, as an important power connector, are widely used in various electrical equipment. For example, mobile devices such as smartphones, tablets, and power banks require the use of DC sockets for charging; New energy vehicles, electric bicycles and other transportation vehicles require the use of DC sockets for charging; Special fields such as medical equipment and industrial control systems also require the use of DC sockets for power connections.

Precautions for using DC sockets
1. Choose a suitable socket: Based on the power, current, and voltage requirements of the electrical equipment, choose the appropriate DC socket model and specifications to ensure stable and reliable power connections.
2. Safe use: Avoid exposing DC sockets to harsh environments such as moisture, high temperature, and dust to avoid affecting their safety performance and service life; At the same time, attention should be paid to avoiding the danger of electric shock during use and ensuring safe use.
3. Maintenance: Regularly inspect the appearance and usage of DC sockets, and promptly handle any abnormalities found; At the same time, keep the socket clean and dry to avoid poor contact or short circuits and other faults.
4. Reasonable resource allocation: When using DC sockets, resources should be allocated reasonably according to actual needs to avoid waste and unnecessary energy consumption. For example, when charging, charging equipment and time can be reasonably selected based on factors such as battery capacity and charging rate to improve energy utilization efficiency.

DC socket is an important electronic connector widely used in various electrical equipment, providing direct current to the equipment. The invention of DC sockets played an important role in promoting the development of electronic devices.
