Description

Technical Field

[0001] The utility model belongs to the technical field of busbar connection, and particularly relates to a busbar connection structure. Background Art

[0002] Busbars use copper bars or aluminum bars as conductors and rely on air or insulating materials for insulation. They are mainly used in important power transmission and transformation sites, such as the connection between transformers, generators and switch cabinets in substations, the main power supply lines in high-rise buildings, or for the transmission of larger currents, and can be used for tree-like branched power transmission, with multiple power feeding points set in the line for direct power taking.

[0003] A connector is needed between busbars to facilitate their connection. In the connection process of traditional busbars, the cable wires in the slots cannot be effectively separated, resulting in a chaotic stacking situation. When maintenance is required, time is wasted because the corresponding cable wires cannot be found, and the work efficiency is low. Therefore, we propose a busbar connection structure. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a busbar connection structure. By setting fixed clamp blocks with holes in two clamp blocks, cables can be inserted separately, avoiding the accumulation of cable wires and affecting maintenance, improving work efficiency, and solving the problems that in the connection process of traditional busbars, the cable wires in the slots cannot be effectively separated, resulting in a chaotic stacking situation, and time is wasted because the corresponding cable wires cannot be found during maintenance, and the work efficiency is low.

The outer surface of the round rod is connected with a sliding clamp block. The left side of the sliding clamp block is connected with a sliding block.

[0007] Furthermore, the top of the protective shell is connected with a base. The top of the base is connected with a fixed cylinder.

[0030] Rotate the screw rod two 32. The screw rod two 32 is threadedly connected to the hole opened in the U-shaped rod 31. The bottom of the screw rod two 32 is restricted by the inner wall of the fixed clamping block 33 and can only rotate and cannot move up and down. Rotating the screw rod two 32 drives the U-shaped rod 31 to lift upward. The U-shaped rod 31 drives the sliding clamping block 34 to fix the cable. Holes are opened in the two clamping blocks, and the cables can be inserted respectively, avoiding the accumulation of cables and affecting maintenance, and improving work efficiency. A base 207 is connected to the top of the protective shell 11. A fixed cylinder 208 is connected to the top of the base 207.

The blocking block 15 fixed on the moving shell 12 moves within the U-shaped groove 13 and compresses the first spring 14. When the moving shell 12 moves to the left of the limiting block 41, the second spring 42 pushes the limiting block 41 to move upward, so that the moving shell 12 is fixed, forming a protection for the cable joint.

[0034] A sliding block 36 is slidably connected to the left side of an insulating main board 53. Copper plates 55 are connected to both the front and back of the insulating main board 53.

By setting the copper plates 55, the joints of the two sides of the cable are effectively connected, thereby achieving the conduction function.

[0035] A specific application of this embodiment is as follows: The cable enters the connector through between the fixed clamping block 33 and the sliding clamping block 34 and contacts the copper plate 55. Rotate the second screw rod 32. The second screw rod 32 is in threaded connection with the hole formed in the U-shaped rod 31. The bottom of the second screw rod 32 is restricted by the inner wall of the fixed clamping block 33 and can only rotate and cannot move up and down. Rotating the second screw rod 32 drives the U-shaped rod 31 to lift upward. The U-shaped rod 31 drives the sliding clamping block 34 to fix the cable to prevent shaking. There is an annular block 203 at the connection between the first screw rod 202 and the fixed block 204. Slightly rotate the first screw rod 202 and it moves downward in the fixed cylinder 208. The connecting rod 205 pushes the arc-shaped block 206 to rotate around the first shaft rod 209 as the central axis. The bottom of the arc-shaped block 206 presses the clamping plate 51 to approach the insulating main board 53 to fix the cable connectors inserted on both left and right sides to prevent them from falling off. After the cable connection is completed, pull the moving shell 12 to slide to the left. The stop block 15 fixed on the moving shell 12 moves in the U-shaped groove 13 and presses the first spring 14. When the moving shell 12 moves to the left of the limit block 41, the second spring 42 pushes the limit block 41 to move upward to fix the moving shell 12, forming protection for the cable connection. When the cable connection needs to be inspected and repaired, press down the limit block 41. The first spring 14 pushes the stop block 15 and the moving shell 12 moves towards the center. The cable connection position is exposed outside, facilitating the staff to repair it.
