[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Embodiment 1

[0021] This embodiment discloses a power battery harness fixing structure, which fixes the harness 3 by means of a snap-fit ​​fixing method, replacing the traditional cable tie fixing method.

[0022] Specifically, the fixing structure includes a wiring harness fixing buckle 4, such as Figure 1 As shown, the wire harness fixing buckle 4 is mainly fixed at the confluence of the wire harness 3 and assembled on the blister isolation plate 1. First, in order to meet the needs of adapting the use of the wire harness, the wire harness fixing buckle 4 is designed with a wire hole 4a for the wire harness 3 to pass through. Secondly, a hook 4b is formed at the end where the open opening of the wire harness fixing buckle 4 is located. Correspondingly, a positioning hole 5 adapted to the wire harness fixing buckle 4 is opened on the blister isolation plate 1. Therefore, after the wire harness fixing buckle 4 is pressed onto the wire harness 3, the hook 4b of the wire harness fixing buckle 4 is hooked at the positioning hole 5 to achieve fixation, thereby fixing the wire harness 3 on the blister isolation plate 1.

[0023] Using the buckle fixing structure of this embodiment to fix the wire harness can improve efficiency, eliminate the process of using cable ties, play a key role in saving labor and ensuring quality. Moreover, installing the wire harness buckle fixing part on the plastic suction isolation board can be completed at one time, which is efficient and simple. However, cable ties need to be cut one by one manually, consuming a lot of time and material costs. Therefore, the design of this wire harness fixing structure is of great significance for improving the production efficiency and quality of products.

[0024] Embodiment Two

[0025] This embodiment discloses a power battery CCS component, which uses the wire harness fixing structure of Embodiment One to fix the wire harness 3 on the plastic suction isolation board 1. The CCS component includes: a plastic suction isolation board 1, an aluminum bar 2, an FPC circuit board, and a wire harness 3;

[0026] Among them, the plastic suction isolation board 1 serves as an insulating bearing structure for the installation and fixation of the aluminum bar 2, the FPC circuit board (not shown in the figure), and the wire harness.

[0027] The aluminum bar 2 and the FPC circuit board are usually connected by nickel sheets. The nickel sheet is soldered to the FPC circuit board at one end and fixed to the aluminum bar by thermal riveting at the other end to achieve signal transmission and current conduction, etc. This is the prior art and will not be elaborated here.

[0028] The plastic suction isolation board 1 is provided with positioning holes 5 to meet the assembly and use of the wire harness fixing buckle 4. Thus, the wire harness 3 is fixed on the plastic suction isolation board 1 through the wire harness fixing buckle 4 and the positioning holes 5 and is welded to the aluminum bar 2 at one end.

[0029] Furthermore, considering that the traditional aluminum bar is fixed to the plastic suction isolation board through thermal riveting posts, and the thermal riveting process is easily affected by the thermal riveting post forming structure, the fixing structure of the aluminum bar is also improved. Specifically, the aluminum bar 2 is fixed to the plastic suction isolation board 1 through the limit card teeth 7 and the positioning posts 9.

[0030] Also as Figure 1 shown, first, an aluminum bar groove 6 is formed on the plastic suction isolation board 1, and the aluminum bar 2 is installed at the aluminum bar groove 6; second, the plastic suction isolation board 1 is made into a positioning post 9 structure, and the positioning post 9 needs to be located within the aluminum bar groove 6. Usually, the positioning post is integrally formed during the injection molding of the plastic suction isolation board 1. Correspondingly, the aluminum bar 2 is provided with through holes 10 for the positioning post 9 to pass through; thirdly, the aluminum bar groove 6 forms a tooth-shaped structure along the top of the side, that is, the limit card teeth 7. Thus, when the aluminum bar 2 is installed at the aluminum bar groove 6 and the aluminum bar 2 and the plastic suction isolation board 1 are attached, the aluminum bar 2 is fixed to the plastic suction isolation board by the combined action of the positioning post 9 and the limit card teeth 7.

[0031] The diameter of the through hole 10 should be greater than the diameter of the positioning post 9. Preferably, the diameter of the positioning post 9 is 5 mm, and the aluminum bar 2 has a through hole with a diameter of 5.5 mm.

[0032] In addition, a wire harness limiting buckle 8 is also provided on the plastic suction isolation board 1. When the wire harness is connected to the aluminum bar 2, the wire harness limiting buckle 8 can play a further role in limiting and fixing.

[0033] Thus, for the CCS component of this embodiment, while using the wire harness fixing buckle 4 to fix the wire harness, the positioning post and the limiting tooth structure on the plastic suction isolation board are also used to quickly fix the aluminum bar, eliminating the traditional aluminum bar hot riveting process, so as to further improve the production efficiency and quality of the product.

[0034] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
