[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components in the distributed system. The main component used to clamp and fix the copper busbar in the bus duct is the clamp.
[0003] During installation and use, the force exerted by the clamp will squeeze the copper busbar, which may easily damage or scratch the insulating film on the outside of the copper busbar.
[0004] The authorization announcement number CN220673345U discloses a clip and a bus duct, the clip comprising a clip body, the clip body having a slot, along the thickness direction of the clip body, the slot passes through two opposite side surfaces and one end surface of the clip body, the clip also comprising an elastic member; the clip body also has a connecting slot, the connecting slot passes through two opposite side surfaces of the clip body; the connecting slot is located on the side wall of the slot and is connected to the slot, and the opening of the connecting slot faces the bottom of the slot; the elastic member comprises a buffer portion and a connecting portion connected to each other, the buffer portion is embedded in the bottom of the slot, the connecting portion is embedded in the connecting slot, and the buffer portion and the side wall of the slot form a space for accommodating a copper busbar.
[0005] The utility model clamps the upper and lower ends of the copper bar with elastic parts to play a fixing and buffering role, buffering the squeezing force from the clamp, but the force-bearing area of the upper and lower ends of the copper bar is small, and the insulating film and buffer parts at the upper and lower ends of the copper bar are still subject to greater pressure. Utility Model Content
[0006] In order to solve the above technical deficiencies, the utility model provides a clamp for fixing a busbar copper bar, which can reduce the pressure on the insulating film on the copper bar.
[0007] The utility model discloses a clamp for fixing a busbar copper bar, comprising a lower clamp and an upper clamp. Slots are arranged at intervals from left to right on the lower clamp, the slots penetrate the front and rear side surfaces and the upper end surface of the lower clamp, one side surface of the slot is arranged as a No. 1 guide slope, the other side surface of the slot is vertical and a No. 1 elastic layer is arranged thereon, an insert block is arranged at a position corresponding to the slot on the lower side of the upper clamp, a side surface on one side of the insert block is arranged as a No. 2 guide slope, the side surface of the insert block away from the No. 2 guide slope is vertical and a No. 2 elastic layer is arranged thereon, the insert block is inserted into the slot, the No. 1 guide slope and the No. 2 guide slope are pressed against each other, the No. 1 elastic layer and the No. 2 elastic layer are spaced from each other, threaded holes are arranged at both ends of the upper end surface of the lower clamp, a long strip through hole is arranged at a position corresponding to the threaded hole on the upper clamp, and bolts are screwed into the threaded holes after passing through the long strip through hole.
[0008] The principle of the above technical solution is to insert the copper busbar covered with an insulating film between the No. 1 elastic layer and the No. 2 elastic layer, and then tighten the bolt to move the upper clamp downward. During the downward movement of the upper clamp, the No. 1 guide slope cooperates with the No. 2 guide slope to make the No. 1 elastic layer and the No. 2 elastic layer close to each other and clamped on the insulating film on both sides of the copper busbar, thereby tightly fixing the copper busbar. Since the side area of the copper busbar is large, the pressure is small, making the insulating film on the copper busbar less likely to be damaged.
[0009] Preferably, the first elastic layer and the second elastic layer are made of silicone elastic layers.
[0010] The utility model provides a clamp for fixing a busbar copper bar, which has the beneficial effect that, through the cooperation of the first guide bevel and the second guide bevel, the first elastic layer and the second elastic layer are tightly clamped on the insulating film on both sides of the copper bar during the process of tightening the bolts, the side area of the copper bar is large, so the pressure is small, and the insulating film on the copper bar is more difficult to be damaged.

[0015] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0016] Embodiment 1:
[0017] like Figures 1 to 4As shown, the utility model discloses a clamp for fixing a bus duct copper bar, comprising a lower clamp 1 and an upper clamp 5. Slots 2 are arranged at intervals from left to right on the lower clamp 1. The slots 2 penetrate the front and rear side surfaces and the upper end surface of the lower clamp 1. One side surface of the slot 2 is arranged as a No. 1 guide slope 4. The other side surface of the slot 2 is vertical and a No. 1 elastic layer 3 is arranged thereon. An insert block 8 is arranged at a position corresponding to the slot 2 on the lower side of the upper clamp 5. The side surface of one side of the insert block 8 is arranged as a No. 2 guide slope 9. The side surface of the insert block 8 away from the No. 2 guide slope 9 is vertical and a No. 2 elastic layer 7 is arranged thereon. The insert block 8 is inserted into the slot 2. The No. 1 guide slope 4 and the No. 2 guide slope 9 are abutted against each other. The No. 1 elastic layer 3 and the No. 2 elastic layer 7 are spaced from each other. Threaded holes are arranged at both ends of the upper end surface of the lower clamp 1. A long strip through hole 6 is arranged at a position corresponding to the threaded hole on the upper clamp 5. A bolt 12 passes through the long strip through hole 6 and is screwed into the threaded hole.
[0018] When the above technical solution is used, the copper busbar 10 coated with the insulating film 11 is inserted between the No. 1 elastic layer 3 and the No. 2 elastic layer 7, and then the bolt 12 is tightened to move the upper clamp 5 downward. During the downward movement of the upper clamp 5, the No. 1 guide bevel 4 cooperates with the No. 2 guide bevel 9 to make the No. 1 elastic layer 3 and the No. 2 elastic layer 7 approach each other and clamp on the insulating film 11 on both sides of the copper busbar 10, thereby tightly fixing the copper busbar 10. Since the side area of the copper busbar 10 is large and the pressure is small, the insulating film 11 on the copper busbar 10 is less likely to be damaged.
[0019] The first elastic layer 3 and the second elastic layer 7 are made of silicone elastic layers.
