[0022] like Figures 1 to 4 As shown, the utility model provides a splash-proof device for a vehicle controller wiring harness connector, including a splash-proof seal 1, the splash-proof seal 1 having a receiving cavity for accommodating the vehicle controller wiring harness connector and a threading hole for allowing the wiring harness to pass through, the threading hole is connected to the receiving cavity, and the splash-proof seal 1 surrounds the wiring harness connector.

[0023] Specifically, if Figures 1 to 4 As shown, the splash-proof seal 1 includes a splash-proof upper cover 2 and a first side wall 10 and a second side wall 11 connected to the splash-proof upper cover 2, the first side wall 10 and the second side wall 11 are arranged opposite to each other and are parallel to each other, and the accommodating cavity is located between the first side wall 10 and the second side wall 11 and below the splash-proof upper cover 2. The length of the first side wall 10 is less than that of the second side wall 11, and the first side wall 10 and the second side wall 11 extend toward the bottom of the splash-proof upper cover 2, and the first side wall 10 and the second side wall 11 form protection for the wiring harness connector.

[0024] The first side wall 10 is the front of the splash-proof seal 1. After the splash-proof seal 1 is assembled, the first side wall 10 is flush with the bottom of the socket end of the vehicle controller 14. The short side design of the first side wall 10 can avoid interference with the edge of the vehicle controller, causing the rubber part to not follow the shape after assembly. The second side wall 11 is the back of the splash-proof seal 1. The long side design of the second side wall 11 can prevent splashing water from directly impacting the surface of the vehicle controller 14, protect the vehicle controller part number label, and facilitate after-sales identification.

[0025] like Figures 1 to 4As shown, the splash-proof seal 1 also includes a first flange 12 and a second flange 13 connected to the splash-proof upper cover 2, and the first flange 12 and the second flange 13 are arranged at the two ends of the splash-proof upper cover 2, and the accommodating cavity is surrounded by the splash-proof upper cover 2 and the first side wall 10, the second side wall 11, the first flange 12 and the second flange 13. The first flange 12 and the second flange 13 are arranged at both ends of the length direction of the splash-proof upper cover 2, and the first side wall 10 is located between the two first flanges 12 arranged at the two ends of the splash-proof upper cover 2, and the two ends of the first side wall 10 are respectively connected to the two first flanges 12 in an integral manner. The second side wall 11 is located between the two second flanges 13 arranged at the two ends of the splash-proof upper cover 2, and the two ends of the second side wall 11 are respectively connected to the two second flanges 13 in an integral manner. The length of the second flange 13 is equal to the width of the second side wall 11, and the length of the first flange 12 is equal to the width of the first side wall 10. The first flange 12 and the second flange 13 are symmetrically designed on both sides of the anti-splash seal 1, which can effectively prevent the impact of road splash water on the tail of the docking plug after assembly.

[0026] like Figures 1 to 4 As shown, the splash-proof seal 1 is designed as an opening, and the openings 9 are symmetrically designed on the left and right sides of the splash-proof seal 1; the openings 9 can be opened to facilitate the disassembly and assembly of the wiring harness connector.

[0027] like Figures 1 to 4 As shown, a threading tube is provided on the first flange 12, and a threading hole is provided on the threading tube. The two ends of the splash-proof seal 1 are respectively the first area and the second area, and a threading tube is provided in each of the first area and the second area. The threading tube is a cylinder, which can ensure that the cable tie can be well matched with the wiring harness for bundling during assembly. When the splash-proof seal 1 is assembled with the vehicle controller 14, the splash-proof seal 1 is distinguished according to the left L mark 3 and the right R mark 4 provided on the top surface of the splash-proof upper cover 2, and two ordinary cable ties 15 are used to fix it in the first area and the second area. The inner diameters of the threading tubes provided in the first area and the second area are different, and they are adapted to different outer diameters of the wiring harness for bundling and assembly.

[0028] like Figures 1 to 4 As shown, a first limiting boss 7 is provided at the end of the threading tube located in the first area. The outer diameter of the first limiting boss 7 is larger than the outer diameter of the threading tube and the two are coaxially arranged. The first limiting boss 7 plays an axial limiting role on the cable tie 15 tied to the threading tube, and can limit the movement of the cable tie 15 due to failure to tighten it into place.

[0029] like Figures 1 to 4 As shown, a second limiting boss 8 is provided at the end of the threading tube located in the second area. The outer diameter of the second limiting boss 8 is larger than the outer diameter of the threading tube and the two are coaxially arranged. The second limiting boss 8 plays an axial limiting role on the cable tie 15 tied to the threading tube, and can limit the movement of the cable tie 15 due to failure to tighten it into place.

[0030] like Figure 1 As shown, two wiring harness connectors are arranged on the vehicle controller, namely, a first connector and a second connector. The splash-proof seal 1 is designed with a splash-proof upper cover 2. After the connectors are assembled, the first connector and the second connector are located in the accommodating cavity, which can avoid the first connector and the second connector being exposed to the outside, and effectively prevent direct impact from splashing water.

[0031] In this embodiment, the splash-proof seal 1 is made of EPDM, which can be directly used in vehicle controller connectors that cannot be arranged in an absolutely dry area, thereby improving the problem of water ingress and rust caused by water splashing and impact after the low-voltage harness-end connector of the vehicle controller is assembled.

[0032] The utility model also provides a vehicle, including a vehicle controller wiring harness connector anti-splashing device. The specific structure of the vehicle controller wiring harness connector anti-splashing device can be referred to Figures 1 to 4 Since the vehicle of the utility model includes the vehicle controller wiring harness connector splash-proof device in the above embodiment, it has all the advantages of the vehicle controller wiring harness connector splash-proof device.

[0033] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
