Description

Technical Field

[0001] This utility model relates to the field of battery connector technology, specifically a flexible aluminum foil connector for batteries. Background Technology

[0002] Battery aluminum foil flexible connectors are flexible conductive connectors formed by connecting multiple aluminum foil sheets or strips together using special welding techniques. This connection method not only retains the good conductivity of the aluminum foil itself, but also gives the connector high flexibility and vibration resistance, making it very suitable for use in complex and ever-changing mechanical environments.

[0003] The aforementioned technologies have certain shortcomings in their application: when installing and connecting battery packs using battery connectors, welding is generally used. However, when subjected to external tension, if the weld is not strong, it may break, affecting the series conductivity of the battery pack.

[0004] To address these issues, this invention provides a flexible aluminum foil connector for batteries. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flexible connector for battery aluminum foil, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a flexible connector for battery aluminum foil, including a flexible connector, a bendable part in the middle of the flexible connector for bending adjustment, a connecting component for connecting and installing multiple flexible connectors on the side wall of the flexible connector, and a bending component for limiting and fixing the connecting component on the left side of the flexible connector.

[0007] The connecting component includes a T-shaped connecting block, which is fixedly connected to the right side wall of the flexible connector. A T-shaped connecting groove is provided on the left side of the flexible connector, and the specifications of the T-shaped connecting groove match those of the T-shaped connecting block. A welding rail groove is provided at the top of the inner wall of the T-shaped connecting groove, and the position of the T-shaped connecting groove matches that of the T-shaped connecting block.

[0008] Through the above technical solution, after the T-shaped connecting block and the T-shaped connecting groove are fitted and locked, the position of the welding rail groove is welded by external welding equipment, thereby improving the connection stability between multiple flexible connecting parts.

[0009] Furthermore, the flexible connector and the T-shaped connector use the same material, and the welded rail groove is used for the welding trajectory after the T-shaped connector and the T-shaped connector are fitted together.

[0010] The above technical solution allows for easy conductive connection between the flexible connector and the T-shaped connector by using the same material.

[0011] Furthermore, the bending assembly includes a bending limiting member one and a bending limiting member two, which are arranged symmetrically front to back and located on the left side of the flexible connector.

[0012] Through the above technical solutions, bending limiting component one and bending limiting component two have the function of bending limiting.

[0013] Furthermore, two grooves are provided on the top left side of the flexible connector. The two grooves are arranged symmetrically front to back. The inner wall of the rear groove is fixedly connected to the inner wall of the first bending limiter, and the inner wall of the front groove is fixedly connected to the inner wall of the second bending limiter.

[0014] Through the above technical solution, the main function of the two grooves is to facilitate the installation of bending limit component one and bending limit component two.

[0015] Furthermore, bending limit component one and bending limit component two can be bent symmetrically.

[0016] Through the above technical solution, the bending limiting component one and the bending limiting component two are symmetrically bent and then abut against and limit the T-shaped connecting block.

[0017] Furthermore, after bending, the first and second bending limiters fit into the T-shaped connecting block and the T-shaped connecting groove and are fixed in place. The flexible connector has mounting holes on both the left and right sides of its top wall.

[0018] The mounting holes described above are primarily used for other types of installation connections. Beneficial effects

[0019] This invention provides a flexible connector for battery aluminum foil. Compared with the prior art, it has the following advantages:

[0020] (1) The battery aluminum foil flexible connector, when installing multiple flexible connectors, locks them together by the cooperation of T-shaped connecting blocks and T-shaped connecting grooves, and simultaneously welds different connection positions. Then, the connection positions of the T-shaped connecting blocks and T-shaped connecting grooves are abutted and fixed by the first bending limiter and the second bending limiter, and welded along the connection, so that multiple flexible connectors have a relatively stable connection, preventing the problem of falling off under the action of external force.

[0026] 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.

[0027] Example 1:

[0028] Please see Figures 1-4 A flexible connector for battery aluminum foil includes a flexible connector 1, a bendable part 5 in the middle of the flexible connector 1 for bending adjustment, a plurality of connecting components 3 for connecting and installing the flexible connector 1 on the side wall, and a bending component 4 for limiting and fixing the connecting components 3 on the left side of the flexible connector 1.

[0029] The connecting component 3 includes a T-shaped connecting block 31, which is fixedly connected to the right side wall of the flexible connector 1. A T-shaped connecting groove 32 is provided on the left side of the flexible connector 1. The specifications of the T-shaped connecting groove 32 match those of the T-shaped connecting block 31. A welding rail groove 33 is provided at the top of the inner wall of the T-shaped connecting groove 32. The position of the T-shaped connecting groove 32 matches that of the T-shaped connecting block 31. The flexible connector 1 and the T-shaped connecting block 31 are made of the same material. The welding rail groove 33 is used for the welding trajectory after the T-shaped connecting block 31 and the T-shaped connecting groove 32 are fitted together.

[0030] In this embodiment of the utility model, the purpose of this arrangement is that, when multiple flexible connectors 1 are installed and connected, the T-shaped connecting block 31 and the T-shaped connecting groove 32 are engaged and locked together, and then an external welding machine is used to weld the connection position of the T-shaped connecting block 31 and the T-shaped connecting groove 32 along the path of the welding rail groove 33.

[0031] Example 2: Please refer to Figures 1-4This embodiment provides a technical solution based on embodiment one: the bending component 4 includes a bending limiting component 42 and a bending limiting component 43. The bending limiting component 42 and the bending limiting component 43 are arranged symmetrically front and back and located on the left side of the flexible connector 1. Two grooves 41 are opened on the top wall of the left side of the flexible connector 1. The two grooves 41 are arranged symmetrically front and back. The inner wall of the groove 41 located at the rear is fixedly connected to the inner wall of the bending limiting component 42, and the inner wall of the groove 41 located at the front is fixedly connected to the inner wall of the bending limiting component 43. The bending limiting component 42 and the bending limiting component 43 can be bent symmetrically. After bending, the bending limiting component 42 and the bending limiting component 43 fit into the T-shaped connecting block 31 and the T-shaped connecting groove 32 and are fixedly positioned. Mounting holes 2 are opened on both the left and right sides of the top wall of the flexible connector 1.

[0032] In this embodiment of the utility model, the purpose of this setting is that, when the T-shaped connecting block 31 and the T-shaped connecting groove 32 are engaged and locked during operation, the bending limiting member 1 42 and the bending limiting member 2 43 bend and limit and fix the T-shaped connecting block 31, and are welded to the T-shaped connecting block 31 by an external welding machine, thereby improving the connection stability between the flexible connecting members 1.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: When multiple flexible connectors 1 need to be installed and connected, the flexible part 5 can be bent to adjust the angle and shape according to the installation position of the flexible connector 1. Other flexible connectors 1 are installed and connected through the connecting assembly 3. The external flexible connector 1 drives the T-shaped connecting block 31 into the inner wall of the corresponding T-shaped connecting groove 32. The external welding machine welds the contact position of the T-shaped connecting block 31 and the T-shaped connecting groove 32 along the welding rail groove 33 to improve the connection firmness between the flexible connectors 1. Then, the bending limiting part 1 42 and the bending limiting part 2 43 are flipped and disengaged. The corresponding groove 41 allows the bending limiting part 1 42 and the bending limiting part 2 43 to abut and limit the welded T-shaped connecting groove 32 and T-shaped connecting block 31. The bending limiting part 1 42, the bending limiting part 2 43 and the T-shaped connecting block 31 are then welded and fixed by an external welding machine, thereby completing the installation and connection of multiple flexible connectors 1. After installation, the overall firmness is high, which can largely avoid the problem of the flexible connectors 1 falling off during connection and improve the connection stability. When other forms of installation are required for the flexible connectors 1, they are assembled and connected through the mounting holes 2 and positioning pins.
