The top of the second housing 12 is provided with heat dissipation holes 19; the heat dissipation holes 19 are arranged in a linear array on the top of the second housing 12; when it is necessary to protect the wire harness during operation, the wire harness can be placed inside the support frame 17, and the EPDM rubber 18 inside the support frame 17 can protect and resist the impact of the wire harness, preventing damage to the wire harness. The buffer springs 16 inside the first housing 11 and the second housing 12 can make the support frame 17 play a better buffering role when impacted, and the convenient snap-fit ​​treatment of the convex block 14 and the snap-fit ​​block 15 makes it easier for operators to handle during installation and maintenance. The heat dissipation holes 19 can dissipate the heat generated by the internal wire harness. Through the above structure, the risk of wire harness damage due to impact can be effectively reduced. The rubber also has excellent aging resistance and weather resistance. It will not harden or crack under harsh environments such as long-term high temperature, high humidity and ultraviolet radiation.

[0026] like Figures 1 to 3 As shown, the first housing 11 has a waterproof layer 21 inside; the waterproof layer 21 is arranged in a surrounding manner on the inner sidewalls of the first housing 11 and the second housing 12; during operation, when water vapor is generated inside the car engine, the waterproof layer 21 inside the protective housing can protect the internal wiring harness and prevent external moisture from entering the protective housing and damaging the wiring harness; through the above structure, the wiring harness can be effectively provided with a first waterproof barrier, and even if used for a long time in a humid environment, it can effectively block external moisture.

[0027] like Figures 1 to 3As shown, heat dissipation fins 31 are fixedly attached to the side wall of the first housing 11. The heat dissipation fins 31 are arranged in a circular array on the side wall of the first housing 11 and are symmetrically arranged. During operation, when the wire harness inside the protective housing generates higher heat, the heat dissipation fins 31 can dissipate the internal heat. The spacing of the heat dissipation fins 31 makes heat dissipation faster. Through the above structure, the heat generated by the wire harness can be effectively and quickly conducted out, and the appropriate spacing can ensure that the air flows smoothly between the fins and carry away the heat.

[0028] like Figures 1 to 3 As shown, a sealing gasket 41 is fixedly connected to the top of the first housing 11; the sealing gasket 41 is located between the first housing 11 and the second housing 12 and is configured to provide a seal; during operation, when the wire harness is fixed inside the protective housing, it can be sealed by the sealing gasket 41 between the housings to prevent substances or moisture from entering the interior due to gaps and damaging the wire harness; through the above structure, gaps can be effectively filled, making the connection tighter and ensuring the integrity and sealing of the overall structure.

[0030] like Figure 1 As shown, a dustproof mesh 61 is provided on the top of the heat dissipation hole 19; the dustproof mesh 61 is located at the top of the second housing 12; during operation, the wire harness inside the protective housing can be protected by the dustproof mesh 61 to prevent external dust and other substances from entering the protective housing through the heat dissipation hole 19 and damaging the wire harness; through the above structure, impurities can be effectively prevented from entering the protective housing, and these impurities can be prevented from adhering to the surface of the wire harness, thus preventing the heat dissipation performance of the wire harness from being affected by dust accumulation.

[0031] like Figures 1 to 3As shown, a limiting clamp 71 is fixedly connected inside the EPDM rubber 18; the limiting clamp 71 is arranged in a linear array inside the EPDM rubber 18; during operation, when fixing the wire harness, the limiting clamp 71 can be used to limit and fix the wire harness, preventing the wire harness from becoming tangled due to excessive wire harness.

When the wiring harness inside the protective shell generates even more heat, the heat dissipation fins 3 can help dissipate heat. 1. Heat dissipation is achieved through the spacing of the heat dissipation fins 31, which facilitates faster heat dissipation. When the wiring harness is fixed inside the protective shell, it can be sealed by the sealing gaskets 41 between the shells to prevent substances or moisture from entering the interior and damaging the wiring harness due to gaps. When the protective shell is fixed in a designated position, it can be quickly and securely fixed to the device in a specific position by the mounting clips 51 to prevent the protective shell from falling off. The wiring harness inside the protective shell is protected by the dustproof mesh 61 to prevent external dust and other substances from entering the interior of the protective shell through the heat dissipation holes 19 and damaging the wiring harness.
