Description

Technical Field

[0001] This utility model relates to the field of copper busbar components, specifically a copper busbar component used for conducting electricity in new energy storage devices. Background Technology

[0002] With the rapid development of new energy technologies, energy storage devices are playing an increasingly important role in power systems. Among these devices, copper busbar assemblies are key electrical connection components, primarily responsible for transmitting current and ensuring the normal operation of the equipment. Traditional copper busbar assemblies typically consist of copper busbars and expansion nuts, used to connect battery modules or other electrical components, ensuring efficient current transmission.

[0003] However, existing copper busbar assemblies still have the following drawbacks in practical applications: First, traditional expansion nuts are usually round and fit into the round expansion holes on the copper busbar. During installation or disassembly, due to excessive torque, the expansion nuts can easily rotate in the holes, leading to unstable connections or even damage to the expansion nuts or the copper busbar. Second, existing copper busbar assemblies typically have the bottom surface of the copper busbar in close contact with the energy storage device (such as a new energy vehicle battery), and the connection is achieved through one-sided contact without any connecting structure. This results in low connection stability, making the copper busbar assemblies susceptible to loosening due to external impacts, pressure, and vibrations during transportation and use. This can cause the copper busbar assemblies to detach from the energy storage device, resulting in poor connection stability between the copper busbar assemblies and the energy storage device, affecting the performance and safety of the equipment. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a copper busbar assembly for conducting electricity in new energy storage equipment, which can effectively solve the technical problems of the expansion nut of existing copper busbar assemblies being prone to rotation due to excessive torque, and the poor connection stability of existing copper busbar assemblies.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a copper busbar assembly for conducting electricity in new energy storage equipment, including a copper busbar, a detachable rivet nut, and a fixing seat. The fixing seat is disposed at both ends of the copper busbar. The surface of the copper busbar is provided with rivet holes, which are elliptical in shape. One end of the rivet nut extends outward to form a fixing part for screwing into the rivet hole. The fixing part is elliptical in shape. One end of the fixing seat is recessed inward to form several square latches for achieving a snap-fit ​​connection. Adjacent square latches are symmetrically arranged. The interior of each square latch is provided with a circular groove. The surface of the fixing seat is provided with several hollow circular fixing channels, which are equidistantly arranged.

[0006] Furthermore, the side of the fixing base is provided with several guide grooves, which extend along the height direction of the fixing base.

[0007] Furthermore, both sides of the fixing seat extend outward to form limiting portions, and the surface of the fixing seat is recessed inward to form limiting grooves that extend along the horizontal direction of the fixing seat.

[0008] Furthermore, the fixing base is recessed inward at both ends near the circular fixing channel to form several positioning holes, and the adjacent positioning holes are symmetrically arranged.

[0009] Furthermore, the mounting base is made of conductive copper.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a copper busbar assembly for conducting electricity in new energy storage devices. By using elliptical rivet holes and elliptical rivet nuts instead of the traditional circular structure, it achieves the function of preventing the rivet nuts from rotating due to excessive torque, making the rivet nut connection more stable. Through the square slots and circular grooves set on the fixed base, the copper busbar assembly can achieve a stable snap-fit ​​connection to the new energy storage device, improving the overall structural stability.

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.

[0018] The following is combined with Figures 1-4 A detailed description of this utility model is provided below:

[0019] A copper busbar assembly for conductive applications in new energy storage devices includes a copper busbar 1, detachable expansion nuts 2, and a fixing base 5. The fixing base 5 is located at both ends of the copper busbar 1. The surface of the copper busbar 1 has expansion holes 3, which are elliptical in shape. One end of the expansion nut 2 extends outward to form a fixing part 4 for screwing into the expansion hole 3. The fixing part 4 is also elliptical in shape. One end of the fixing base 5 is recessed inward to form several square latches 7 for engaging connection. Adjacent square latches 7 are symmetrically arranged. Each square latch 7 has a circular groove 9 inside. The surface of the fixing seat 5 is provided with several hollow circular fixing channels 11, and adjacent circular fixing channels 11 are arranged at equal intervals. Several guide grooves 8 are provided on the side of the fixing seat 5, and the guide grooves 8 extend along the height direction of the fixing seat 5. Both sides of the fixing seat 5 extend outward to form limiting parts 12. The surface of the fixing seat 5 is recessed inward to form limiting grooves 6 that extend along the horizontal direction of the fixing seat 5. The two ends of the fixing seat 5 near the circular fixing channels 11 are recessed inward to form several positioning holes 10, and adjacent positioning holes 10 are symmetrically arranged. The fixing seat 5 is made of conductive copper.

[0020] The copper busbar 1 has an unlimited length structure. The guide groove 8 on the side of the fixing base 5 extends along the height direction, which facilitates alignment and positioning during installation, reduces installation errors, and improves installation accuracy. The limiting parts 12 on both sides of the fixing base 5 and the limiting groove 6 on the surface are designed to effectively prevent the copper busbar 1 assembly from shifting during use, ensuring the stability of the structure. At the same time, the positioning holes 10 at both ends of the fixing base 5 are symmetrically arranged, which facilitates precise positioning during installation and further improves assembly accuracy. The fixing base 5 is made of conductive copper, which ensures that the entire assembly has good conductivity and is suitable for high conductivity scenarios of new energy storage equipment.
