Point-contact-typed explosion-proof capacitor for conductive column

Abstract

The invention discloses a point-contact-typed explosion-proof capacitor for a conductive column, and relates to the capacitor which comprises an aluminum shell and a capacitor body encapsulated in the aluminum shell. The upper end of the capacitor body and the lower end of the capacitor body are connected with first copper foil, the upper end of the aluminum shell is provided with an explosion-proof end cover, the inner side of the explosion-proof end cover is provided with a bridging-typed explosion-proof piece, and a fixed bridge is arranged between the bridging-typed explosion-proof piece and the explosion-proof end cover. The lower side of the bridging-typed explosion-proof piece is provided with second copper foil, a solid rivet is arranged in the bridging-typed explosion-proof piece, the bottom inside the aluminum shell is provided with a lower positioning sleeve, the capacitor body is inserted into the positioning sleeve, and the lower end of the bridging-typed explosion-proof piece is provided with an elongated baffle which abuts against the upper portion of the capacitor body. The point-contact-typed explosion-proof capacitor is simple in structure and easy to implement, the assembling procedures of the capacitor are simplified for a refrigerator with the capacitor, production efficiency is improved, internal heat dissipation is enhanced as well, and explosion-proof performance is enhanced.

Description

Technical field: [0001] The invention relates to a capacitor, in particular to a conductive column point contact type explosion-proof capacitor.

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned capacitors can play a good role in starting and running in ordinary electrical equipment, but under the condition of high temperature and long-term vibration, the stability of its internal parts is poor, and it is easy to cause poor contact of components, especially rivets and If there is no bridging protection at the copper foil connection, it is prone to open circuit phenomenon, and the capacitor of the same specification is larger in size, so it is not suitable for smaller electrical equipment
