Capacitor explosion-proof block

Abstract

The invention provides a capacitor explosion-proof block which includes an explosion-proof block body. An installation cavity is arranged in the upper end face of the explosion-proof block body. Annular slots are symmetrically arranged at the bottom of the installation cavity. A wiring hole is arranged in each annular slot, and the wiring holes penetrate the explosion-proof block body. Through holes are respectively arranged in the two sidewalls of the installation cavity. A groove is also arranged in the upper end face of the explosion-proof block body. A first reinforcing rib, a second reinforcing rib, a third reinforcing rib and a stopper are arranged on the lower end face of the explosion-proof block body. The second reinforcing rib and the third reinforcing rib are placed in parallel.One end of the second reinforcing rib and one end of the third reinforcing rib on the same side are connected with the stopper. The first reinforcing rib is arranged at the other ends of the second reinforcing rib and the third reinforcing rib on the same side. The first reinforcing rib, the second reinforcing rib, the third reinforcing rib and the stopper form a placing slot. The capacitor explosion-proof block of the invention has the advantages of simple and compact structure, convenience of welding, good explosion-proof effect, high safety factor and long service life.

Description

technical field [0001] The invention relates to an explosion-proof block, in particular to a capacitor explosion-proof block. Background technique [0002] A capacitor is a component that can store charges, and it is also one of the most commonly used electronic components. It is widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. During the use of capacitors, rivets are usually used to connect electrodes, copper foil, explosion-proof blocks, cardboard, sealing rings and capacitor upper covers. Rivets are placed in the cavity of the explosion-proof block, and copper foil is placed in the slot at the bottom of the explosion-proof block. The rivets are not only used for fixing, but also play the role of conduction and explosion-proof. The two ends are respectively connected with the terminal and the copper foil. Time high voltage overheating causes internal high voltage to bulge up under high pressure, pulling away ...

AI Technical Summary

Problems solved by technology

The explosion-proof block placement groove in the prior art is a rectangular placement groove with one end open and composed of three reinforcing ribs. The disadvantage of this structure is that the welding stability is poor and it is not easy to weld, resulting in poor explosion-proof effect and low safety factor.
