[0003] Currently, there are usually two forms of battery cell arrangement inside the battery pack, namely module and CTP battery cell stacking; no matter which form is used, copper bars need to be used for connection to form a passage. When the copper bars are used for a long distance, they need to be fixed with copper bar buckles to prevent shaking, abnormal noise, and serious functional failure. The design principle of traditional copper bar buckles is to redesign and develop according to different battery packs and internal spaces. This traditional design will result in the need to develop different buckle molds for different projects, with high R&D and manufacturing costs. At the same time, the scope of application of the buckles is limited to the corresponding developed battery packs and is not scalable. Utility Model Content

[0023] The buckle body 1 of the utility model is provided with a flexible buckle 11 for clamping the copper bar 4, so as to facilitate the clamping of copper bars 4 of different thicknesses, and then a copper bar buckle can be used to adapt to different copper bar thicknesses, thereby reducing costs; then the buckle body 1 is threadedly connected with the buckle base 2 to realize the lifting and lowering adjustment of the buckle body 1 on the upper end of the buckle base 2, and then designed into a structure with ductility in height. After the buckle body 1 is rotated to a suitable height, it is locked by the anti-loosening nut 3, thereby strengthening the stable connection between the buckle base 2 and the buckle body 1. The utility model enables the copper bar buckle to be applicable to different battery packs, and the height is adjusted in the battery pack, which reduces mold development, thereby lowering the R&D cost and manufacturing cost, and making it more economical.

[0024] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower part of the buckle body 1 is a threaded sleeve with a threaded groove at the lower end, and the upper part of the buckle base 2 is a screw section with an external thread. The screw section is threadedly connected to the threaded sleeve, and the connection is simple and stable, and the adjustment is convenient. The anti-loosening nut 3 is threadedly connected to the screw section, which facilitates the adjustment of the anti-loosening nut 3 and ensures the stability of the anti-loosening nut 3 on the buckle base 2.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that the upper end of the anti-loosening nut 3 is a first friction surface, and the lower end of the buckle body 1 is a second friction surface. The first friction surface abuts against the second friction surface, and the friction force can be used to enhance the stability of the anti-loosening nut 3 to avoid accidental loosening of the anti-loosening nut 3, thereby enhancing the stable fit between the buckle base 2 and the buckle body 1.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that a limiting ring located between the screw section and the connecting end is provided in the middle part of the snap base 2, and the limiting ring abuts against the upper end of the external structural member 5, and then the snap base 2 is snapped onto the external structural member 5 by utilizing the cooperation between the limiting ring and the connecting end, thereby ensuring the stability of the snap base 2 and the snap body 1.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that a through hole is opened on the buckle body 1, the flexible buckle 11 is connected to the inner wall on one side of the through hole, and the copper busbar 4 is clamped between the flexible buckle 11 and the inner wall on the other side of the through hole, and the clamping method is simple and convenient.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that the inner wall on the other side of the through hole is a vertical surface in contact with the copper busbar 4, which can better fit with the copper busbar 4 and thus enhance the stability of the copper busbar 4.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the buckle body 1 is an elastic snap ring, and the side of the elastic snap ring facing the copper busbar 4 is a vertical surface in contact with the surface of the copper busbar 4, which can better fit with the copper busbar 4 and thus enhance the stability of the copper busbar 4.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the connection end is provided with an external thread that cooperates with the external structural member 5 or is provided with an elastic hook that cooperates with the lower end of the external structural member 5, and the elastic hook is arranged obliquely upward, and the threaded connection or the clamping connection are both very simple connection methods, which can ensure the stability of the buckle base 2. It should be explained that, preferably, the buckle base can also be consistent with the principle of ordinary automotive low-voltage wire harness buckles, pre-opening installation holes on external structural members such as sheet metal, and then the buckle is directly pressed into the hole in the vertical direction of the installation hole, and the barbs of the buckle cooperate with the installation hole to prevent the buckle from falling off, that is, fix it.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
