When using DC socket, we should pay attention to its characteristics. When using DC socket, we should better deal with some common faults. What are the specific ones? Let's give you a detailed introduction.
In our daily life, I believe that many people will come into contact with different kinds of plugs every day. There are mobile phone plugs, headphone plugs, power plugs, audio and video plugs, DC plugs and so on. Do we know enough about DC plugs? What are the components of DC plugs, DC plugs and DC plugs? What is the connection between the sockets and how the DC sockets are made up?
Although DC plugs and sockets are often used in our life, we do not have enough knowledge about them. DC plugs are used in household appliances such as TV sets, induction cookers, electric fans, computers and so on. Then the corresponding DC sockets have directional keyway, fork contact shrapnel, insulation base, and longitudinal. The DC socket is composed of two fork contact shrapnels, which are positioned at the center of the base and are arranged vertically and horizontally. One end of the fork contact shrapnel is a wiring port, which is exposed on the top of the base cylinder for connecting the input power soft wires or cables. The other end of the DC socket fork contact shrapnel is connected by two substrates. Elastic arm.
DC socket components should be flexible enough, the socket has enough contact pressure to ensure that the DC plug is inserted firmly, socket socket should also be corrosion-resistant and wear-resistant, to ensure that the DC plug and socket socket parts are in good contact, while locking the pin of the plug can not rotate, otherwise it will have unsafe factors and impact. 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 should be close between the insertion surfaces when inserting.
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 shell, wash it with alcohol, stick it with 502 glue after drying, and install it after drying thoroughly. Some people often use 502 glue to stick it to death when the earphone shell is easy to fall off. In fact, this method is not advisable, because, first, the permeability of 502 glue is very strong, and it is easy to flow into the headphone unit to stick it. Damage, secondly, 502 adhesive is too strong, which makes it difficult to repair again. It is suggested that we use 704 silica gel and fish ball universal gel, and pay strict 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.
