Problems solved by technology

[0002] At present, capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning circuits, energy conversion, control circuits, etc. Large, high temperature causes the shell to burst. The shell often suffers from serious oil leakage, body expansion, breakdown, and easy damage. The waterproof and sealing effects are poor.

Abstract

The invention relates to a waterproof and explosion-proof capacitor, which belongs to the technical field of capacitors. It includes a metal shell, capacitor core, cover, terminal block, explosion-proof plate, terminal, fuse and temperature control switch. The metal shell is fixed with an explosion-proof plate, the terminal is fixed on the explosion-proof plate, and the lower end is connected to the capacitor core. , the terminal is fixed on the cover, and connected to the upper end of the terminal through the fuse and the temperature control switch respectively. The cover is composed of three layers of materials, which are insulating layer, waterproof layer and aluminum cover layer from inside to outside. There is also a sealing gasket between the cover and the metal shell; when the temperature of the capacitor core is too high, the invention protects itself by disconnecting the temperature control switch, which not only has a good explosion-proof function, but also has good sealing and waterproof performance.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a waterproof and explosion-proof capacitor. Background technique [0002] At present, capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning circuits, energy conversion, control circuits, etc. Large, high temperature causes the shell to burst. The shell often suffers from serious oil leakage, body expansion, breakdown, and easy damage. The waterproof effect and sealing effect are poor. Contents of the invention [0003] Aiming at the defects and deficiencies in the prior art, the present invention proposes a waterproof and explosion-proof capacitor. When the temperature of the capacitor core is too high, the temperature control switch is disconnected to protect itself. It not only has a good explosion-proof function, but also is sealed and waterproof. Good performance. [...
