Commonly Used DC Power Jack Types

The dc socket is widely used in our daily life. The dc socket refers to a power socket matched with a special power supply for computer monitors. The dc socket consists of a horizontal socket, a fork-shaped contact shrapnel, a vertical socket, an insulating base, and a directional keyway. Combined, the two fork-shaped contact shrapnels of the dc socket are positioned at the center of the base, forming a vertical and horizontal arrangement that is not connected to each other.

The dc socket is divided into two packages: SMT chip package and DIP plug-in package.

Application areas of dc sockets:
1. Audio-visual products: MP3, Bluetooth headsets, smart speakers, etc.;
2. Digital products: digital cameras, digital video cameras, etc.;
3. Remote control: remote control for vehicles, rolling doors, home anti-theft products;
4. Communication products: mobile phones, car phones, telephones, building equipment, PDAs, etc.;
5. Household appliances: TVs, microwave ovens, rice cookers, electric fans, electronic body scales, electronic fat scales, electronic kitchen scales, etc.;
6. Security products: video walkie-talkies, monitors, etc.;
7. Toys: electronic toys, etc.;
8. Computer products: cameras, monitors, etc.;
9. Fitness equipment: treadmills, massagers, etc.;
10. Medical equipment: sphygmomanometer, clinical thermometer, hospital call system, etc.

How to choose a dc socket?

Taking "30V/0.5A" as an example, it shows that the allowable current is 0.5A, the voltage level is 30V, and the maximum safe current of 0.5A. If it is greater than 0.5A, it will generate heat, oxidize, and malfunction. 30V is the rated index. There is a difference between the two.
