How to deal with the blockage of sound holes in DC plugs and sockets? We will give you a detailed introduction below.
In our daily life, I believe that many people will come into contact with different kinds of plugs every day, such as mobile phone plugs, headphone plugs, power plugs, audio and video plugs, DC plugs and so on. Do we have enough knowledge about DC plugs, what are the components of DC plugs, what are the connections between DC plugs and DC sockets, and how to group DC sockets? Yes.
Although DC plugs and sockets are often used in our life, we do not know enough about them. DC plugs are used in household appliances: TV sets, induction cookers, cookers, fans, computers and so on. Then the corresponding DC sockets have directional keyway, fork contact shrapnel, insulation base, longitudinal socket, horizontal socket and two fork-shaped DC sockets. Contact shrapnel is positioned at the center of the base and arranged in longitudinal and transverse directions. One end of the fork-shaped contact shrapnel is a wiring port, which is exposed on the top of the base cylinder for connecting the input power soft wire or cable. The other end of the DC socket fork-shaped contact shrapnel is composed of two elastic arms interconnected by the base.
DC socket components should be flexible enough, the socket has enough contact pressure to ensure that the DC plug is firmly inserted. The socket socket should also be corrosion-resistant and wear-resistant, ensure that the DC plug and socket socket parts are in good contact, and lock the plug pin of the plug can not rotate, otherwise it will produce unsafe factors and affect the insertion performance. The soft-wire fixing device of the converter should be able. To withstand normal tension and torsion, in order to prevent electric shock accidents, DC plugs and sockets in the socket, the surface between the socket should be basically tight.
In view of the above common sense knowledge between the DC plug and the DC socket, we know how to use the product correctly to prevent all accidents.
For the damaged case, you can remove the earphone case, wash it with alcohol, stick it with 502 after drying, and then install it after drying thoroughly. Some earphone cases are easy to fall off and often stick it to death with 502 glue. In fact, this method is not advisable, because, first, the permeability of 502 glue is very strong, it is easy to flow into the headphone unit to damage it. Second, the bonding of 502 is too strong, to give it again. It is suggested that we use 704 silica gel and fish ball universal gel, and pay close attention to the dosage.
For the plugged earphone holes, I suggest that you remove the headphones and clean them with alcohol. I don't think there is any possibility of repairing the membrane deterioration of the headphones.
