Common Faults And Solutions Of DC Sockets

In our daily life, I believe that many people will come into contact with different and various plugs every day, including mobile phone plugs, headphone plugs, power plugs, audio and video plugs, and DC plugs, etc. Do you have enough understanding, what are the components of the DC plug structure, what is the connection between the DC plug and the DC socket, and how the DC socket is composed.

Although we often use DC plugs and sockets in our lives, we lack sufficient understanding of them. DC plugs are used in household appliances: TVs, induction cookers, rice cookers, fans, computers, etc., then it corresponds to The DC socket has a directional keyway, a fork-shaped contact shrapnel, an insulating base, a vertical socket, and a horizontal socket. One end is a wiring port, which is exposed on the top surface of the base cylinder for connecting the input power cord or cable. The other end of the DC socket fork-shaped contact spring is composed of two elastic arms interconnected by the base.

The components of the DC socket must have sufficient elasticity, and the pins must have sufficient contact pressure to ensure that the DC plug is inserted firmly. To lock the pin of the plug, it cannot be rotated, otherwise it will cause unsafe factors and affect the insertion performance. The flexible cord fixing device of the converter must be able to withstand normal tension and torsion. In order to prevent electric shock accidents, the DC plug and socket are When mating, the mating surfaces should be basically tight.

In view of the common sense knowledge between the above dc plug and dc socket, we know how to use the product correctly to prevent all accidents.

If the shell is damaged, you can disassemble the earphone shell, wash it with alcohol, and glue it with 502 glue after drying. After the glue is completely dry, you can install it. Some people often use 502 glue to stick it when the earphone shell is easy to fall off. Death, in fact, this approach is not advisable, because, first, 502 glue is very permeable, and it is easy to flow into the headphone unit and damage it; second, 502 glue is too strong, which makes it difficult to repair again. Use 704 silica gel and fish bead all-purpose glue, and pay strict attention to the dosage.
