Insulating mounting assembly of power filter

Abstract

The invention discloses an insulating mounting assembly of a power filter, which is mounted in a rectangular mounting hole of a filter shell of the power filter and comprises a threading plate, a first clamping plate and a second clamping plate, wherein the first clamping plate is positioned above the threading plate, and the second clamping plate is positioned below the threading plate; the upper edge and the lower edge of the first clamping plate are provided with a first upper clamping groove and a first lower clamping groove respectively, the upper hole wall of the rectangular mounting hole is arranged in the first upper clamping groove, the upper edge of the threading plate is arranged in the first lower clamping groove, and the upper edge and the lower edge of the second clamping plate are provided with a second upper clamping groove and a second lower clamping groove respectively. The lower edge of the threading plate is arranged in the second upper clamping groove, the lower hole wall of the rectangular mounting hole is arranged in the second lower clamping groove, and the sum of the height of the second upper clamping groove and the height of the second lower clamping groove is smaller than the height of the first lower clamping groove. The connection stability of the threading plate and the filter shell is obviously improved, and the subsequent work of the power supply filter can be smoothly carried out.

Description

technical field [0001] The invention relates to a partial structure of a power filter, in particular to an insulating installation assembly of a power filter. Background technique [0002] The electrical signal in the power filter needs to be led out through the lead-out terminal. In many cases, in order to ensure that the signal in the power filter is free from or less disturbed by the outside world, the filter shell will use a metal shell, so the lead-out wire of the power filter Or lead-out terminals need to be connected with insulating mounting parts to ensure a good insulation function between the signal output line and the metal shell. In order to ensure that the insulating mounting part does not fall off during subsequent work and affect the normal use of the power filter, the insulating mounting part should be stably installed on the filter housing. [0003] At present, there are mainly two traditional fixing methods for the insulation mounting parts of the power fi...

AI Technical Summary

Problems solved by technology

Among them, for the high-current power filter limited by the internal space structure, due to the small space, it cannot be fixed by means of mounting screws or screws and nuts. Bonding and fixing by applying adhesive to the edge of the notch

[0004] For the above-mentioned power filter that installs the insulating mounting parts by gluing, its wires directly pass through the threading holes of the insulating mounting parts. Difficult to bend, when assembling it out of the insulating mount and shaping it, or when the lead-out wire is moved during use, the insulating mount will be subject to a huge pulling force from the lead-out wire, which will easily tear or pull off the adhesive , eventually causing the insulating mount to come off the housing
