Description

Technical Field

[0001] The utility model relates to the technical field of box-type capacitors, in particular to a box-type capacitor with shockproof pins. Background Art

[0002] A container is a device that holds electric charge. In an AC circuit, since the direction of the current changes with time in a certain relationship, a changing electric field is formed between the plates of the capacitor, so the capacitor is also conductive. In order to avoid leakage of the capacitor, a box capacitor is used. Most of the existing box capacitors directly lead out the positive and negative poles of the capacitor core. After the capacitor is plugged and unplugged many times, the positive and negative poles of the capacitor core are easily pulled out, so that the capacitor core cannot be electrically connected to the outside world, which greatly reduces the service life of the capacitor. In addition, the existing box capacitor is not convenient for replacing and testing the capacitor core. The capacitor is fixed by a rigid connection method such as welding. The rigid connection method is used inside various sports machines, which makes the PCB control board and the surface capacitor vibrate, which easily causes the positive and negative poles of the capacitor core to fall off, poor contact, and potential safety hazards. In view of this, the existing problems are studied and improved, and a box capacitor with shockproof pins is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.
