What is the specific situation of the headphone socket and what problems need our attention? We will give you detailed details below.

Headphone socket in the use of the side, its headphone socket protector live, overload, short-circuit protection characteristics, can not be arbitrarily adjusted to change, so as to avoid affecting the working function of the headphone socket. And after the new installation or operation for a certain period of time, it is necessary to check its operation mode in the form of switching-on and power-on. If the circuit breaker in the headphone socket can not be disconnected, the internal circuit of the footnote headphone socket has obstacles and needs to be checked. But the circuit breaker can break, the footnote works normally, and can continue to use.
Under normal conditions, the contact point of the headphone socket is exposed to be closed and the contact resistance is zero at this time. However, if the contact point of the headphone socket is disconnected, the contact resistance will be infinite, because the contact resistance will change from zero to infinite instantaneously during disconnection. In order to measure the contact resistance of the contact parts of the headphone socket essentially, it is carried out at the contact lead-out end. Therefore, the contact resistance measured essentially includes the contact parts outside the contact surface and the conductor resistance of the lead-out wire itself. The collective resistance plus the film resistance is called the true contact resistance. The intrinsic measurement including conductor resistance is called total contact resistance.
When choosing headphone sockets, don't try to be cheap, think that low-cost headphone sockets can also be used, but there is a big gap in value. It may be inferior headphone sockets, and inexpensive headphone sockets are made of plastic structure as the shell, although the comparison is cheap. However, the safety, compression resistance and durability are not so good. Usually, there will be some potential safety hazards when it is used.
