Description

Busbar lap joint structure

Technical Field

The utility model relates to a rectifying equipment technical field, concretely relates to female overlap joint structure of arranging.

Background

The busbar is a high-current conductive product, and generally, when the current load reaches or exceeds 250A, the busbar is required to replace a lead to lead in and out load current, and the busbar is suitable for electrical engineering of high and low voltage electrical appliances, switch contacts, distribution equipment, bus ducts and the like. Traditional female arranging is in the use, often needs the overlap joint to use, the operation personnel generally are in the same place two female direct crimping that arrange, but this kind of overlap joint mode is neglected the contact position very easily because contact surface is uneven or the contact area contact failure problem that leads to too little, and then make contact resistance grow in the use, then local female electric current of arranging is also bigger and bigger, produces partial discharge, the temperature risees, increase equipment running loss, but also has the female risk of row of burning out. In addition, the existing busbar is rigid, the bending radian cannot achieve an ideal effect when the busbar is bent in an arc shape, and the busbar is labor-consuming to bend.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of prior art, provide one kind and make the increase of overlap joint area, contact resistance is little female overlap joint structure of arranging, and concrete scheme is as follows:

a busbar lapping structure comprises a busbar body, wherein first bending grooves are formed in the upper side and the lower side of the busbar body, mutually corresponding toothed lapping surfaces are formed in the left end and the right end of the busbar body, a plurality of threaded through holes penetrating through the busbar body are formed in the toothed lapping surfaces, a plurality of support legs are arranged on the front side and the rear side of the busbar body, lapping holes are formed in the support legs, and second bending grooves are formed in the positions, close to the busbar body, of the upper side and the lower side of each support leg; the busbar bodies are lapped through the toothed lapping surfaces and fixed together through fastening bolts corresponding to the threaded through holes.

Based on the above, the toothed lapping surface between the busbar bodies is coated with the electric composite grease.

Based on the above, still be equipped with a plurality of fixed orificess on the female body of arranging.

Based on the above, the support legs and the corresponding busbar body are of an integral structure.

Based on the above, the material of the busbar body is copper.

The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:

1. the utility model provides an among the female overlap joint structure that arranges, pass through between the female body cusp faying face carries out the overlap joint to together through the fastening bolt who corresponds with the screw thread through-hole, this kind of structural design has increased the area of contact of female overlap joint department of arranging, can effectively avoid arranging between the body because of contact failure or contact surface cause the resistance increase and then produce partial discharge's phenomenon too for a short time, the extension is arranged the life of or equipment.

2. In the utility model, the upper side and the lower side of the busbar body are both provided with a first bending groove, the structural design is favorable for bending the busbar, the upper side and the lower side of the support leg are both provided with a second bending groove near the busbar body, and the structural design is favorable for bending the support leg; to sum up, the utility model provides a female construction of being convenient for of arranging, and labour saving and time saving.

3. The utility model discloses in, the coating of cusp faying surface department through arranging between the body has electric power compound fat, has further guaranteed the electric conductive property between the female body of arranging.
