[0033] The harness distributor 4 is provided at the wire outlet 2 and is provided with harness holes for sealingly leading out each wire of the harness.

[0034] Specifically, the present invention optimizes the structure of the wiring harness fixing method and the wiring harness outlet 2 of the battery pack, and has good compatibility with the battery pack. The wiring harness is fixed by sealing the wire body using the outlet 2, the harness port 3 and the harness distributor 4 to ensure the fixing and sealing requirements of the wiring harness, and the harness distributor 4 is used to complete the distribution and management of the wiring harness, thereby optimizing the direction and distribution of the wiring harness and meeting the actual wiring harness outlet requirements.

[0035] In a preferred embodiment, the sealing base 1 is a groove-shaped structure, and the wire outlet 2 is vertically arranged on the side wall of the sealing base 1 .

[0036] Specifically, the sealing base 1 is a groove-shaped structure. After the sealing base 1 is filled with sealant, the top of the sealant is flush with the outer shell surface of the wire harness outlet sealing device 7, thereby enhancing the sealing effect and reducing leakage points.

[0037] In a preferred embodiment, the wire outlet 2 is a rectangular opening vertically provided on a side of the sealing base 1 away from the wire outlet 2 .

[0038] Specifically, the wire outlet 2 is a vertically arranged rectangular opening, which helps to optimize the wire outlet position and direction of the wire harness, so that the wire harness passes through the wire harness distributor 4 and enters the sealing base 1.

[0039] In a preferred embodiment, the top of the cable tie opening 3 is located at the top of the sealing base 1, and the bottom of the cable tie opening 3 is an arc-shaped structure.

[0040] Specifically, the bottom of the harness opening 3 is an arc angle to facilitate the wiring harness to be taken out, and to prevent the wiring harness from causing friction when it shakes here, which may cause the harness leather to be worn for a long time and thus affect the wiring harness signal transmission.

[0041] In a preferred embodiment, the wire harness distributor 4 includes a base 41 . The base 41 is disposed in the wire outlet 2 and is adapted to the shape of the wire outlet 2 . The wire harness hole passes through the base 41 .

[0042] Specifically, the wiring harness distributor 4 of the present invention is arranged in the wire outlet 2, and the base 41 is a rectangular structure adapted to the wire outlet 2. The wiring harness passes through the wiring harness distributor 4 and enters the sealed base 1, solving the problem of friction with the right-angle edge when the wiring harness passes directly through the wire outlet 2, and further optimizing the position and direction of the wiring harness outlet.

[0043] In a preferred embodiment, a sealing ring 42 is further included. The sealing ring 42 is arranged on the side of the base 41 facing the sealing base 1. A corresponding harness hole is formed in the sealing ring 42, and each wire of the harness passes through the sealing ring 42 into the sealing base 1.

[0044] Specifically, the present invention leads out the wiring harness through the sealing ring 42, further improving the sealing performance. At the same time, a corresponding wiring harness hole is formed in the sealing ring 42, so that each wire of the wiring harness can be led out independently, reducing the interference caused by the crossing of the wiring harness, which is beneficial to the management and maintenance of the wiring harness.

[0045] In a preferred embodiment, the wiring harness includes at least a positive line, a negative line and a communication line, and the sealing ring 42 includes a first sealing ring 421 for leading out the positive line, a second sealing ring 422 for leading out the negative line and a third sealing ring 423 for leading out the communication line.

[0046] Specifically, the sealing ring 42 of the present invention fits the wire body of the wiring harness, and the wiring harness holes corresponding to the sealing ring 42 are respectively used for the positive wire, negative wire and communication wire outlets, further optimizing the position and direction of the wiring harness outlets and completing the sealing conditions.

[0047] In a preferred embodiment, the first sealing ring 421, the second sealing ring 422 and the third sealing ring 423 are arranged adjacent to each other. Specifically, the multiple sealing rings 42 are arranged closely adjacent to each other to ensure compact space and improve space utilization.

[0048] In a preferred embodiment, the back of the sealing base 1 is provided with reinforcing ribs 5 for increasing strength.

[0049] Specifically, the present invention adopts cross reinforcement ribs, and the reinforcement ribs 5 are arranged on the back of the sealing base 1 to improve the strength and prevent the strength at this location from being insufficient and failing the vibration test.

[0050] In a preferred embodiment, the sealing base 1 is filled with sealant 6. Specifically, the wire outlet 2 is sealed with sealant 6, so that the wire outlet is in a sealed state, thereby meeting its fixing and sealing requirements.

[0051] A battery pack, such as Figure 6 As shown, it includes an outer shell 81 and a battery module 82 arranged in the outer shell 81, and the outer shell 81 is provided with a connector 83 for connecting an external load. It also includes a wire harness outlet sealing device 7 as in any embodiment, which is arranged on the battery module 82, and the wires of the battery module 82 are led out from the outlet 2 and connected to the connector 83.

[0052] Specifically, the battery cell is placed in the battery module 82, and the wire harness outlet sealing device 7 serves as the upper cover of the battery module 82, leading the wires of the battery cell from the outlet 2 and connecting them to the connector 83, which is used to connect to an external load.

[0053] The present invention leads out the wires of the battery module 82 by setting a wire harness outlet sealing device 7 that is adapted to the battery pack. It does not need to be designed according to the structure of the battery pack and has good adaptability. The wire harness is fixed by sealing the wire body using the wire outlet 2, the wire bundle port 3 and the wire harness distributor 4 to ensure the fixed sealing requirements of the wire harness, and the wire harness distributor 4 is used to complete the distribution and management of the wire harness, thereby optimizing the direction and distribution of the wire harness and meeting the actual wire harness outlet requirements.
