[0001] The utility model relates to the technical field of wire harness switching, in particular to a wire harness waterproof switching structure. Background Art

[0002] The requirements for the waterproof level of automotive wiring harnesses are constantly being improved to ensure the service life and quality of automotive electronics. The assembly parts of the wiring harnesses of external connection components such as automotive cameras involve the requirements for waterproof performance. The existing waterproof adapter structure cannot block water vapor from entering the interior of the components that need to be connected, making the service life of the connection components relatively short.

[0003] The prior art discloses a wiring harness waterproof transfer structure, which uses a PCB board as a transfer bridge, uses a sheath to assemble and fix the appearance, and finally uses a potting type waterproof glue to completely seal it, so that water vapor cannot pass through this transfer point from the core wire, thereby achieving a waterproof effect and ensuring the service life of the external connection component. It includes a wiring harness and a core wire corresponding to the external connection component. The length direction of the corresponding wiring of the wiring harness is exposed to the overall length end face of the wiring harness. The exposed end of the corresponding wiring is connected to the connection end of the core wire through a PCB board. The entire part of the PCB board is encapsulated with waterproof glue, and the waterproof glue extends to the overall outer ring surface of the wiring harness and the outer ring surface of each core wire, so that the gas at both ends of the core wire cannot be connected, effectively solving the problem that the wiring harness cannot be completely waterproof.

[0004] However, in actual use, although the above-mentioned wiring harness waterproof adapter structure effectively solves the problem that the wiring harness cannot be completely waterproof, it is inconvenient to replace the wiring harness after the wiring harnesses are connected. At the same time, the reusability of this structure is poor. Utility Model Content
