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 longitudinal 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-type contact shrapnel is composed of two elastic arms interconnected by the base.
The components of the DC socket should have sufficient elasticity, the pin should have enough contact pressure to ensure that the DC plug is inserted firmly, and the socket socket should also be corrosion-resistant and wear-resistant. , to ensure that the mating part of the DC plug and socket is in good contact, and at the same time to lock the plug of the plug can not 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 Torque, in order to prevent electric shock accidents, when the DC plug and socket are inserted, 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 the earphone shell easily. 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 to damage it, second, 502 glue is too strong, making it difficult to repair again, I suggest you Use 704 silica gel and fish bead all-purpose glue, and pay strict attention to the dosage.
