[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a power busbar connection device includes two busbars 1, with the copper busbars at the docking ends of the two busbars 1 exposed. The device is characterized by a connection mechanism at the docking ends of the two busbars 1, comprising a connection mechanism and an elastic mechanism. The connection mechanism includes a first conductive clamp 2 and a second conductive clamp 6, which are respectively located on opposite sides of the docking ends of the busbars 1. The top and bottom ends of the second conductive clamp 6 are arc-shaped, and the inner walls of the arc-shaped portions at the top and bottom ends of the second conductive clamp 6 match the rounded corners of the copper busbars 1. An outwardly protruding protruding plate 3 is integrally formed on the docking surface of the arc-shaped portion of the second conductive clamp 6.

[0018] In this embodiment: First, the exposed copper busbar ends of the two busbars 1 are aligned. Then, the first conductive clamp 2 and the second conductive clamp 6 are placed on both sides of the copper busbar of the busbar 1. Then, the first conductive clamp 2 is moved and the connecting mechanism is tightened. At this time, the first conductive clamp 2 and the second conductive clamp 6 clamp the docking end of the busbar. At this time, the elastic mechanism deforms under the pressure, realizing the tight connection of the exposed copper busbars of the two busbars 1.

[0019] Please refer to this carefully. Figure 1 and Figure 2 The connecting mechanism includes a screw 4 integrally formed on the side of the protruding plate 3 near the first conductive clamp 2. The first conductive clamp 2 has a circular groove inside that can be inserted into the screw 4. The outer wall of the screw 4 is threaded with a tightening nut 5. The tightening nut 5 in the tightened state is used to press the first conductive clamp 2.

[0020] In this embodiment: during the docking process of the first conductive clamp 2 and the second conductive clamp 6, the first conductive clamp 2 drives the round hole to be inserted into the screw 4. After docking, the tightening nut 5 is threaded onto the outer wall of the screw 4, and a wrench is used to drive the tightening nut 5 to rotate. The rotating tightening nut 5 is tightened until the tightening nut 5 is completely tightened. At this time, the first conductive clamp 2 and the second conductive clamp 6 are clamped at the exposed copper busbar position of the busbar 1.

[0021] Please refer to this carefully. Figure 3 The elastic mechanism includes multiple sets of elastic guide plate assemblies. The elastic guide plate assemblies are fixedly installed on the inner sides of the first conductive clamp 2 and the second conductive clamp 6. Each set of elastic guide plate assemblies includes a first conductive spring 7 and a second conductive spring 8. The first conductive spring 7 and the second conductive spring 8 in the set of elastic guide plate assemblies are symmetrically distributed and have an "eight" shaped structure. The multiple sets of elastic guide plate assemblies are equidistantly distributed along the height and length directions on the inner sides of the first conductive clamp 2 and the second conductive clamp 6.

[0022] In this embodiment: During the tightening process of the connecting mechanism, the elastic guide plate assembly is deformed under pressure. If the connecting mechanism becomes loose during the long-term use of the busbar 1, gaps will be generated between the first conductive clamp 2 and the second conductive clamp 6 and the exposed copper busbar of the busbar 1. At this time, the first conductive spring 7 and the second conductive spring 8 will elastically reset. At this time, the first conductive spring 7 and the second conductive spring 8 will tightly fit the exposed part of the copper busbar of the busbar 1, avoiding poor conductivity caused by the loosening of the connecting mechanism.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
