Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0014] Such as Figure 1 to Figure 3 As shown, the copper bar connection structure includes input copper bar 1, output copper bar 2 and bolt 3, and the input copper bar and output copper bar are arranged in a cross. The cross section of the input copper bar is "I"-shaped, with long grooves on both sides 4. Nuts 5 are set in the long slot. The nuts can be hexagonal nuts or square nuts. The nuts can be moved to a designated position to fix the output copper bar without drilling, and will not change the flow trace of the current, offsetting the input copper bar. The surface of the nut on the leaning side is flat, which can increase the contact area. There is a conductive pad 6 between the input copper bar and the output copper bar. The upper and lower surfaces of the conductive pad are flat, and the bolts pass through the output copper bar and the ...

Abstract

The invention discloses a copper bar connecting structure. The copper bar connecting structure comprises an input copper bar, an output copper bar and bolts, wherein the input copper bar and the output copper bar are arranged in a crossed manner, the cross section of the input copper bar is I-shaped, long grooves are formed in the two sides of the input copper bar, nuts are arranged in the long grooves, and a conductive pad is arranged between the input copper bar and the output copper bar; after sequentially penetrating through the output copper bar and the conductive pad, the bolts are fixed on the nuts in the long grooves; the cross sections of the long grooves are in a shape like the Chinese character tu, and raised lines are arranged on the inner surfaces of the open ends of the long grooves; grooves are formed in the surfaces of single sides of the nuts, and the raised lines are clamped in the grooves. The copper bar connecting structure has the advantages that the input copper bar is designed to be I-shaped, and the nuts can slide in the long grooves, so that the output copper bar can be fixed in any position in the long grooves without punching holes; current flows in from the input copper bar, flows across the conductive pad and then flows out from the output copper bar.

Description

technical field [0001] The invention relates to a connection structure, in particular to a copper bar connection structure. Background technique [0002] There will be many distribution cabinets in a substation. The copper bars in the existing power distribution cabinets are flat and long. The wider copper bars are the power input copper bars, and the thinner copper bars are the power supply bars. Output copper bar, a relatively large copper bar will arrange multiple parallel output copper bars. [0003] According to the change of the current and the number of input lines, drill holes and install bolts on the power input copper bars to fix the output copper bars. This connection method is time-consuming and labor-intensive, and the current flow lines on the input copper bars after drilling will also change. Contents of the invention [0004] The invention aims at the deficiencies of the prior art, and provides a copper bar connection structure that can be directly instal...
