[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] In a first aspect, this embodiment provides a via rubber sleeve for a wiring harness.

[0030] Reference Figure 1 and Figure 5 The through-hole rubber sleeve for wire harness provided by the utility model is now described. The through-hole rubber sleeve for wire harness comprises a mounting frame 1, a sealing disk 2 and a rubber sleeve 3. The mounting frame 1 is made of a light plastic. The mounting frame 1 is arranged at the through-hole of the sheet metal to provide support for the overall structure of the present embodiment.

[0031] Specifically, the material of the mounting frame 1 can be polyurethane. Polyurethane is a plastic material widely used in the engineering field. PU has high strength, good wear resistance, chemical corrosion resistance and temperature resistance, and also has good elasticity and pressure resistance. Polyurethane products are widely used in machinery, automobile manufacturing, construction, electronics and other industrial fields.

[0032] The material of the mounting frame 1 can be polypropylene. Polypropylene is a low-density, high-molecular-weight, high-rigidity and high-strength plastic material, and its weight is only about one-third of that of metal. It has good corrosion resistance, heat resistance, fatigue resistance and electrical insulation. Polypropylene products are widely used in the fields of automobiles, electrical appliances, medical treatment and food packaging.

[0033] The mounting frame 1 may be made of polycarbonate. Polycarbonate is a special engineering plastic with the characteristics of high strength, high rigidity, low smoke, non-toxicity, high temperature resistance and excellent transparency. Polycarbonate products are widely used, especially in the fields of electronics, medical treatment and food packaging.

[0034] The material of the mounting frame 1 can be polyamide. Polyamide is an engineering plastic with high strength, high hardness and strong plasticity. It has excellent wear resistance, cutting resistance, impact resistance and durability. Polyamide products are widely used in the fields of automobiles, electronics, machinery, construction and home appliances.

[0035] The material of the mounting frame 1 can be polystyrene. Polystyrene is an amorphous polymer with low density, good mechanical properties and high water absorption. Polystyrene products are widely used in electronics, home appliances, food packaging, construction and other fields.

[0036] The sealing disc 2 is mounted on the mounting frame 1, and a first through hole 21 for passing the wiring harness is provided on the sealing disc 2. After the overall structure is mounted on the sheet metal wire hole through the mounting frame 1, the sealing disc 2 seals the wire hole to prevent water in the external environment from entering the interior of the sheet metal structure through the gap between the wire hole and the wiring harness. The rubber sleeve 3 is in an "L" shape, and the inner diameter of the rubber sleeve 3 is the same as the diameter of the first through hole 21. One end of the rubber sleeve 3 is connected to the sealing disc 2, and the rubber sleeve 3 is connected to the first through hole 21. The rubber sleeve 3 is made of the same material as the sealing disc 2, and the two are integrally formed by an injection molding process. The sealing disc 2 and the rubber sleeve 3 are made of soft rubber, and the sealing disc 2 and the rubber sleeve 3 can be adaptively deformed according to the direction of the wiring harness. When the mounting frame 1 is mounted on the wire hole, the sealing disc 2 is adaptively deformed under the pressure applied by the mounting frame 1, thereby sealing the gap between the wire hole and the mounting frame 1.
