Problems solved by technology

This device allows the capacitor to fully exchange heat and dissipate heat with the outside world. However, when the capacitor is fixedly installed on the sealed cavity through the fixing bracket, the positions of the two sealing rings need to be adjusted accurately so that the two The two sealing rings can be kept in contact with the upper and lower end faces of the capacitor, which undoubtedly improves the installation accuracy requirements of the device.

Abstract

Provided is a device for fixing and protecting a capacitor (10). The device comprises: a seal box body (30), the seal box body (30) comprising a bottom plate (32), a through hole (35) being provided on the bottom plate (32), a head end (11) of the capacitor (10) entering the interior of the seal box body (30) through the through hole (35) to be fixed and electrically connected to an internal circuit; and a seal assembly (40) which independently uses the head end (11) of the capacitor (10) to form a seal with the seal box body (30) at the position of the through hole (35). The device is simple in structure and convenient in installation, and has both a heat dissipation effect and a protective effect on the capacitor.

Description

technical field [0001] The present invention relates to an assembly for capacitors and, in particular, to a device for securing and protecting capacitors. Background technique [0002] Capacitors are electronic components widely used in various electronic or electrical equipment, such as DC isolation, coupling, bypass, filtering, tuning loops in circuits, or energy conversion or control. [0003] In order to meet the higher protection level requirements of electronic equipment, capacitors usually need to be installed inside a closed device. For example, in U.S. Patent US2001 / 0021094, the capacitor is set in the sleeve, and the sleeve is sealed and fixed on the plate through the lug on the edge of the cup mouth. The upper space of the plate is a sealed space, so that the capacitor as a whole is in the In a sealed environment and isolated from possible pollutants such as dust or water vapor from the outside. However, in this structure, since the entire capacitor is completel...
