When it comes to DC sockets, many people only think of sockets and ignore them. Sockets are visible to us directly, such as bull sockets. DC sockets are just electronic components with relatively small volumes, also known as DC power sockets, which are like connectors. Dc sockets are not only diverse in classification, but also widely used. Mainly used in electronic and related products, with the continuous development and progress of technology, people will design various convenient things on the functions that were not available in many products before. For example, in the past, cars were very old-fashioned manual transmission, and there was no navigation device at all. Now, there are not only many other comfortable devices.
Classification of DC sockets
1、 Classified by purpose: laptop DC socket, car DC socket, Bluetooth DC socket.
2、 According to the size of the center pin of the DC socket, it is divided into 3.5DC socket, 3.0DC socket, and 2.5DC socket.
3、 According to packaging: SMT DC socket and plug-in DC socket. (1.65mm/1.3mm/1.1mm/1.0mm/0.7mm/0.5mm and other sizes)

Principle analysis of DC sockets
When the power socket coil is energized, the iron core in the coil generates strong electromagnetic force, which attracts the armature to drive the spring, causing contacts 1 and 2 to disconnect and 1 and 3 to connect. When the coil is powered off, the spring resets the spring, causing contacts 1 and 2 to connect and 1 and 3 to disconnect. We only need to connect the circuit that needs to be controlled between contacts 1 and 3 (referred to as normally open contacts) or between contacts 1 and 2 (referred to as normally closed contacts), and we can use a DC socket to achieve a certain control purpose.
If there is a short-circuit fault in the AC 220V rectifier and filter circuit of the DC socket, and the fuse is burned during startup, it is necessary to first check whether the rectifier diode has a short circuit and whether the filter capacitor has serious leakage. If there is, it must be replaced in a timely manner.

What is the function of a DC socket
DC sockets have a significant impact on our daily lives, both in terms of their characteristics and the scope of their use. But do you know the specific functions of this type of socket?
Many friends may think that this type of socket is only suitable for use on computers when they hear that it is a power cord for computer monitors. However, in fact, besides being used on computers, it has many other functions. For example, the following products can all use DC sockets:
Firstly, digital cameras, digital cameras and other digital products;
Secondly, all products that can provide us with communication functions, such as mobile phones, iPads, telephones, building equipment, etc;
Thirdly, remote control products that can utilize infrared sensing, such as vehicles, anti-theft doors, roll up doors, etc;
Fourthly, household appliances such as microwaves, electronic scales, rice cookers, televisions, etc;
Fifth, security products such as monitors and visual walkie talkies that need to be used in public places;
Sixth, ordinary electronic toys and other toy products;
Seventh, medical equipment used in hospitals, treadmills and massage chairs used in gyms and homes, as well as computer products such as cameras and recording pens.
