Bus duct jack box based on mechanical interlocking structure

Abstract

The invention discloses a bus duct jack box based on a mechanical interlocking structure. The bus duct jack box comprises a box body, an interlocking assembly, a supporting assembly and a pressing assembly. The middle and the upper surface of the left side face of the box body are of open structures. Symmetrical first cutting grooves are formed in the edge of the opening of the front side plate ofthe box body. The right end of the upper surface of the box body is rotationally connected with a box cover through a pin shaft. The box cover is of a 7-shaped structure. Second cutting grooves are formed in the left and right sides of the inner wall surface of the vertical part of the box cover. The second cutting groove corresponds to the first cutting groove in position. A cooling fan is arranged in the middle of the rear side surface of the box body. The bus duct jack box based on the mechanical interlocking structure is firm in fixation, simple and convenient to operate, improved in installation efficiency and safety performance, novel in design, improved in practical performance, convenient to popularize and apply, capable of delaying aging of electrical elements and eliminating potential safety hazards, and the interlocking structure is used for buckling and clamping.

Description

technical field [0001] The invention relates to the technical field of bus duct plug-in boxes, in particular to a bus duct plug-in box based on a mechanical interlock structure. Background technique [0002] With the rapid development of my country's urban modernization, people's living standards continue to improve, and the country's requirements for electricity and personal safety are getting higher and higher. Bus ducts for power transmission trunk lines are widely used in hotels, office buildings, commercial plazas, stadiums, Airports, theaters, hospitals, schools, industrial factories, aerospace enterprises, military enterprises, shipbuilding enterprises and other construction sites that need to use electricity, so the safety and stability of busway is very important. The branch line of the existing busway is equipped with a plug-in switch box branch, and the existing busway socket, due to its structure, the copper pins are not directly inserted into the corresponding ph...

AI Technical Summary

Problems solved by technology

The branch line of the existing busway is equipped with a plug-in switch box branch, and the existing busway socket, due to its structure, the copper pins are not directly inserted into the corresponding phase sequence during the plugging process of the main line current of the busway and the plug-in box. The outer side of the copper pin piece, so its contact resistance is large, the overload capacity is low, it is easy to shift and skew, its heat dissipation performance is poor, and it is easy to cause a short circuit due to the excessive temperature rise of the pin, and even cause the failure of burning equipment in serious cases. In addition, the existing The bus duct plug-in boxes are fixed by multiple sets of bolts, which are cumbersome to disassemble and require professional tools to operate. After symmetrical disassembly and assembly, the bolt holes are easily damaged, which will lead to slipping wires and cannot be locked. For this reason, We propose a busway plug-in box based on a mechanical interlock structure to solve the above defects
