Abstract

The utility model discloses a grounding device of a bus duct. The bus duct comprises a grounding box, a bus duct housing and a bus. The bus is arranged in the bus duct housing; the bus duct housing comprises a pair of H-shaped section bars and a pair of U-shaped section bars; the two sides of the H-shaped section bars are provided with flange plates; the flange plates at the two sides are connected through a web plate; the bus duct housing is movably arranged at the bottom of the grounding box through an H-shaped section bar; the grounding box is internally provided with wiring pins; a pair of pin copper sheets of the wiring pins are exposed out of the bottom of the grounding box; the web plate of the H-shaped section bars movably connected with the grounding box is provided with an inserting hole groove; a grounding row is arranged at one side edge of the length direction of the inserting hole groove; the grounding row is vertical to the web plate; and the pair of the pin copper sheets of the wiring pins are clamped on the thickness of the grounding row. The grounding device of the bus duct has the advantages of high mechanical strength and convenient installation.

Description

A kind of earthing device of bus duct

Technical field

The utility model relates to a kind of bus duct, especially relates to a kind of earthing device of bus duct, belongs to technical field of electricity.

Background technology

The earthing mode of original bus duct adopts earthing bar to rivet mutually with bus duct shell, and an earthing bar is riveted on bus duct shell, and the while arranges socket on the shell of the jack box of correspondence position, realizes the grounding connection of bus duct and jack box; Such earthing mode mechanical strength is poor, affects overall appearance simultaneously.

Summary of the invention

It is high that the purpose of this utility model is to provide a kind of mechanical strength, and the earthing device of bus duct easy for installation.

The utility model is achieved by the following technical programs:

A kind of earthing device of bus duct, bus duct comprises junction box, bus duct shell, bus, bus is arranged in bus duct shell, bus duct shell comprises a pair of H section bar, a pair of U-shaped material, H section bar both sides are flange plate, the flange plate of both sides connects by web, a pair of H section bar is symmetrical arranged, and by a pair of U-shaped material, connect the web of a pair of H section bar, bus duct shell is movably arranged on junction box's bottom by a H section bar, junction box's inside is provided with connector pin, the a pair of pin copper sheet of connector pin exposes junction box's bottom, the web of the H section bar being flexibly connected with junction box is provided with socket groove, socket groove is rectangle, its length direction is parallel to flange plate, on a side of the length direction of socket groove, be provided with earthing bar, earthing bar is arranged on that side that H section bar is connected with junction box, earthing bar is perpendicular to web, the a pair of pin copper sheet of grounding pin is connected on the thickness of earthing bar.

The utility model is by when web upper punch socket groove, and earthing bar is one time punching molded, has saved this procedure of riveted joint earthing bar, saves time cost; The a pair of pin copper sheet of grounding pin tightly clamping is lived earthing bar, guarantees jack box and the compactness that bus duct shell is connected, and guarantees mechanical strength.

Advantage and disadvantage of the present utility model, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
