DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0020] As Figures 1-3 collectively shown, this embodiment of the CCS component for fixing a wire harness based on a bracket includes an aluminum bar 3, a wire harness 4 electrically connected to the aluminum bar 3, a connector 5 connected to the wire harness 4, and a cable tie 6; it should be noted that, as Figure 1 shown, the number of aluminum bars 3 is multiple, and the aluminum bars 3 are used to realize electrical connection between external battery cells; the wire harness 4 and the aluminum bar 3 are structurally and electrically connected by ultrasonic welding, and it is used for voltage acquisition and temperature acquisition; the connector 5 is used to connect the circuit of an electronic device and transmit current or signals; the above technical features are all prior arts, hereby explained.

[0021] This embodiment further includes a plastic suction isolation board 1 that supports the aluminum bus bar 3. The plastic suction isolation board 1 keeps several aluminum bus bars 3 on the same plane. The wall thickness of the plastic suction isolation board 1 is 0.5 mm. In this embodiment, the plastic suction isolation board 1 replaces the traditional injection molding isolation board, simplifies the structural design, and makes the mold manufacturing simpler. An injection molding bracket 2 that cooperates with the cable tie 6 to fasten the wire harness 4 is provided on the plastic suction isolation board 1. The injection molding bracket 2 is formed with a cable tie fitting 8 and a wire harness fitting 9 that are on the same side as the wire harness 4 and protrude.

[0022] The injection molding bracket 2 is located below the aluminum bus bar 3 in the hierarchical structure and is inserted into the corresponding connection hole of the aluminum bus bar 3 through the aluminum bus bar connection rivet head 7 formed thereon. It can be understood that in this embodiment, the plastic suction isolation board 1, the injection molding bracket 2, and the aluminum bus bar 3 are in a stacked structure. Then, the injection molding bracket 2 is limitedly arranged between the plastic suction isolation board 1 and the aluminum bus bar 3 to strengthen the stability of the injection molding bracket 2, thereby strengthening the fastening reliability of the wire harness 4.

[0023] As Figure 3 shown, the number of the cable tie fittings 8 is multiple. Each cable tie fitting 8 is formed with a main body portion 10 extending upward. In this embodiment, the cable tie fittings 8 are implemented in a paired and grouped manner. It can be understood that the cable tie fittings 8 are grouped in pairs of two, and the two cable tie fittings 8 in each group are symmetrically arranged with each other. Each cable tie fitting 8 fastens a wire harness 4.

[0024] The main body portion 10 and the edge portion of the board surface of the injection molding bracket 2 form a first strengthening portion 11. An avoidance hole 13 is opened at a position of the main body portion 10 close to the first strengthening portion 11, and an avoidance notch 12 is opened directly above the avoidance hole 13. The first strengthening portion 11 is used to improve the stability and structural strength of the main body portion 10. The cooperation of the avoidance hole 13 and the avoidance notch 12 enables the cable tie 6 to be wound, and when the wire harness 4 inside the cable tie 6 is simultaneously fastened, the limiting and fastening effect of the cable tie fitting 8 on the wire harness 4 is achieved.

[0025] A first upper limiting portion 14 that is bent and matched with the main body portion 10 is formed on the main body portion 10 on one side of the avoidance notch 12. The first upper limiting portion 14 is used to limit the wire harness 4 directly above it.

[0026] The number of the wire harness fittings 9 is multiple and matches the number of the cable tie fittings 8. Each wire harness fitting 9 cooperates with a cable tie fitting 8 and the two are arranged in a staggered manner as Figure 3 shown.

[0027] The wire harness fitting 9 includes an upright portion 15 and a second upper limit portion 16 that is bent and fitted to the upper end thereof. A second strengthening portion 17 is formed on the back surface of the upright portion 15. It can be understood that the second upper limit portion 16 is used to limit the wire harness 4 directly above it. In the case where the cable tie fitting 8 and the wire harness fitting 9 are misaligned and fitted with each other, the second upper limit portion 16 and the first upper limit portion 14 jointly limit the wire harness 4. The second strengthening portion 17 is used to strengthen the connection strength of the wire harness fitting 9.

[0028] In this way, the CCS component for fixing the wire harness based on the bracket disclosed by the present utility model changes the complex injection-molded separator plate into a simple thermoformed separator plate, simplifies the complex structural design, enables simple mold production, enables a fast product production process, saves the material usage, and thus meets the overall weight reduction and cost reduction requirements of the CCS component; using the injection-molded bracket can effectively solve the problem that the wire harness on the thermoformed separator plate is not firmly fixed; it provides effective support for the lightweight, cost saving, and reliability of the new energy energy storage battery module.

[0029] The above embodiments are not limitations to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the technical scope of the present utility model also fall within the protection scope of the present utility model.
