Common DC power jack specifications

DC Jack sockets are widely used and can be used in various electronic devices and mechanical equipment that require DC power. For example, DC sockets can be used in laptops, tablets, mobile phone chargers, routers, cameras, speakers, monitors, printers, scanners, etc. The advantages of DC sockets are simple structure, easy installation, firm connection, high transmission efficiency, long life, simple maintenance, etc.

The following points should be noted when purchasing and using DC sockets:

According to the parameters of your own equipment and power supply, choose the appropriate DC socket specifications and models, especially the diameter of the center pin, rated current and rated voltage, which should match the equipment and power supply, otherwise it may cause poor contact, short circuit, overheating, damage and other problems.

According to the installation space and method of your own equipment, choose the appropriate DC socket installation method, such as patch type, direct plug-in type, sinking plate type, etc. Different installation methods have different advantages and disadvantages, such as the patch type occupies a small space, but is easy to fall off; the direct plug-in type has a firm connection, but occupies a large space; the sinking plate type has a compact structure, but is complex to install, etc.

When using a DC socket, be careful to keep the plug and socket clean and dry, and avoid dust, moisture, oil and other pollutants entering the socket, which will affect the contact effect and conductivity. If you find that the plug and socket are dirty or oxidized, you can wipe or blow them off gently with a soft cloth or cotton swab.

When using a DC socket, pay attention to the direction and strength of plugging and unplugging, and avoid using too much or too little force, or plugging and unplugging crookedly or inverted. This may cause damage or deformation of the plug and socket, affecting the stability and reliability of the connection. If the plug and socket are found to be loose or stuck, they should be replaced or repaired in time.

When using a DC socket, be careful to avoid long-term high temperature, high humidity, strong light, strong magnetism and other harsh environments, which may cause aging, discoloration, cracking, corrosion and other problems of the plug and socket. If the plug and socket are found to have obvious changes or damage, they should be replaced or repaired in time.
