Technical Field

[0001] The utility model relates to the field of power equipment, in particular to a connection structure of a soft copper busbar. Background Art

[0002] Flexible connector, copper busbar flexible connector, tinned copper braided wire flexible connector is suitable for various high-voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches and automobiles, locomotives and other related products as flexible connectors. It uses bare copper wire or tinned copper braided wire (stranded wire) and is made by cold pressing. The interface of the copper busbar flexible connector is welded and formed in one go using molecular diffusion welding technology. The product has good quality, strong conductivity, high current bearing capacity, low resistance value and durability.

Therefore, they need to go back and select a suitable copper busbar for replacement, which will greatly affect work efficiency. Therefore, a soft copper busbar connection structure is needed to solve this problem. Utility Model Content

The two ends of the stranded wire group are respectively welded to the two copper sheets. The copper sheets are provided with mounting holes. The sleeves are hollow boxes with one end open. Through holes are symmetrically provided at the upper and lower ends of the sleeves. The size of the through holes corresponds to the size of the mounting holes.

[0006] Preferably, an electrode connection block is provided on the side of the sleeve.

[0007] Preferably, a pushing block is provided in the sleeve, and sliding grooves are symmetrically provided on both sides of the inner wall of the sleeve. Slide blocks are symmetrically provided on the left and right sides of the pushing block, and the slide blocks are slidably connected to the sliding grooves. A threaded hole is provided at the bottom of the sleeve, and a push rod is threadedly connected to the threaded hole. One end of the push rod is fixedly connected to the bottom of the pushing block, and the other end of the push rod is connected to a rotating knob, and the rotating knob is located at the bottom of the sleeve.

[0008] Preferably, an insulating sleeve is provided on the outer periphery of the twisted wire group, and the insulating sleeve includes an insulating pad and a snap-fit ​​structure.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting a sleeve and combining multiple copper bars at the same time, the cross-sectional area of ​​the copper bar can be changed, thereby increasing or reducing the maximum current of the copper bar. It can be freely combined according to different currents, replacing the traditional copper bar. Different types of copper bars need to be used according to different electrical appliances, which can prevent the maintenance work from being delayed due to the lack of suitable models.

[0012] 2. By setting a pushing block on the sleeve, multiple copper bars can be pressed by the pushing block to prevent the copper bars from shaking up and down, resulting in gaps between the multiple copper bars to form parallel circuits.

[0013] 3. By setting a snap-on structure on the insulating sleeve and setting the snap-on structure as a binding strap and a fixing seat, multiple copper bars can be fastened by the snap-on structure to avoid gaps between the copper bars, which would cause gaps between the multiple copper bars to form parallel circuits.
