Technical Field

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries; wiring harnesses have a very wide range of applications.

[0003] The invention patent with publication number CN217333683U discloses a multi-core automotive wiring harness cable, comprising: five wiring harness cores; a composite shielding layer disposed on the outside of the wiring harness cores; a sheath surrounding the five wiring harness cores; a first reinforcing layer disposed on the outside of the sheath; a second reinforcing layer disposed on the outside of the first reinforcing layer; Z-shaped spring posts arranged laterally and closely between the first and second reinforcing layers; elastic particles filling the gaps between the Z-shaped spring posts; a hardening layer disposed on the outside of the second reinforcing layer; and a waterproof layer disposed on the outside of the hardening layer. This invention enhances the overall strength of the cable by setting the first and second reinforcing layers; significantly enhances the overall compressive strength of the cable by setting the Z-shaped spring posts and elastic particles between the first and second reinforcing layers; and enhances the overall hardness and waterproofness of the cable by setting the hardening layer and the waterproof layer.

[0004] In existing wire harnesses, the shielding mesh is completely wrapped around the wire cores during use. When transmitting data, there is some interference between the different groups of wire cores. At the same time, the wire cores are not waterproof during use, and water entering the wire cores will cause corrosion. To solve the above problems, this application proposes an ultra-short multi-core shielded waterproof wire harness. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes an ultra-short multi-core shielded waterproof wire harness.

At the same time, the sealing end caps abut against both ends of the wire harness body through rubber gaskets, and the tightening tape is wrapped around the wire cores, which can improve the sealing effect at both ends of the wire harness body. When the outer insulation layer is broken, the water-swelling rubber strip layer expands upon contact with water, which can seal the damaged area, thereby improving the waterproofness of the wire harness body during use and solving the problems mentioned in the background art.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-4 As shown, the present invention proposes an ultra-short multi-core shielded waterproof wire harness, comprising a wire harness body 1 and wire cores 2. The multiple strands of wire cores 2 are disposed in the inner cavity of the wire harness body 1. The inner cavity of the wire harness body 1 is provided with a shielding mesh ring 4. The inner wall of the shielding mesh ring 4 is provided with a shielding cross 5. The ends of the shielding cross 5 are respectively fixedly connected to the inner wall of the shielding mesh ring 4. The inner cavity of the shielding mesh ring 4 is divided into four sets of wire-passing cavities by the shielding mesh ring 4, and the wire cores 2 are respectively passed through the wire-passing cavities.

[0028] Both ends of the wire harness body 1 are movably inserted with sealing end caps 11, and each sealing end cap 11 is fixedly connected with a tightening and closing band 14.

[0029] The outer surface of the wire harness body 1 is integrally formed with rubber protrusions 9.

[0030] It should be noted that the shielding cross 5 and the shielding mesh ring 4 are an integrated structure. The wire cores 2 are respectively inserted into the shielding cross 5. The shielding cross 5 can block the wire cores 2, which can reduce the mutual interference between the wire cores 2 when transmitting data. In addition, the shielding mesh ring 4 and the shielding cross 5 together can improve the shielding effect of the wire harness body 1 when in use, thereby improving the stability of the wire harness body 1 when transmitting data. The talc powder 3 is filled and wrapped on the surface of the wire core 2. When the wire harness body 1 is bent, it reduces the friction between the wire core and the shielding mesh ring 4 and the shielding cross 5, thus improving the protection of the wire core 2.

[0031] In this embodiment, as Figure 1 As shown, the outer wall surface of the wire harness body 1 is provided with an insulating outer layer 8. The insulating outer layer 8 and the rubber protrusions 9 are integrally formed. The rubber protrusions 9 are equidistantly arranged around the surface of the insulating outer layer 8, and heat dissipation grooves 10 are formed between the rubber protrusions 9.

[0032] It should be noted that the rubber protrusion 9 can lift the wire harness body 1, and when the wire harness body 1 is pulled, it can reduce the friction between the insulating outer layer 8 and the object, thereby improving the protection of the wire harness body 1. The heat dissipation groove 10 can improve the heat dissipation effect of the wire harness body 1.

[0033] In this embodiment, as Figure 2 As shown, the inner wall of the insulating outer layer 8 is compositely connected with a water-swellable adhesive strip layer 7, and the outer surface of the shielding mesh ring 4 is wound with a mica tape 6, which is located on the inner wall of the water-swellable adhesive strip layer 7.

[0034] It should be noted that the mica tape 6 is used to improve the insulation of the wire harness body 1.

[0035] In this embodiment, as Figure 3 As shown, the inner cavity of the sealing end cap 11 is provided with a rubber pad 13, and the rubber pad 13 abuts against the end surface of the wire harness body 1.

[0036] It should be noted that the rubber pads 13 abut against the end surfaces of the wire harness body 1, which can improve the sealing performance of the connection between the sealing cap 11 and the two ends of the wire harness body 1.

[0037] In this embodiment, as Figure 2 and Figure 3 As shown, the inner wall of the sealing cap 11 is provided with insertion grooves 12 at positions corresponding to the rubber protrusions 9, and the insertion grooves 12 are inserted into the rubber protrusions 9.

[0038] It should be noted that the inner wall of the sealing end cap 11 is connected to the rubber protrusion 9 through the insertion groove 12, which can increase the contact area between the sealing end cap 11 and the wire harness body 1, thereby increasing the friction and improving the stability of the installation of the sealing end cap 11.

[0039] The working principle and usage process of this utility model: The shielding cross 5 and the shielding mesh ring 4 are an integrated structure. The wire cores 2 are respectively inserted into the shielding cross 5. The shielding cross 5 can block the wire cores 2, reducing mutual interference between them during data transmission. The shielding mesh ring 4 and the shielding cross 5 work together to improve the shielding effect of the wire harness body 1 during use, thereby improving the stability of the wire harness body 1 during data transmission. The talcum powder 3 is filled and coated on the surface of the wire core 2. When the wire harness body 1 is bent, it reduces the friction between the wire core and the shielding mesh ring 4 and the shielding cross 5, improving the protection of the wire core 2. Sealing end caps 11 are movably inserted into both ends of the wire harness body 1. The inner wall of the sealing end cap 11 is connected to the insertion groove 1. 2. The rubber protrusion 9 is inserted into the wire harness body 1, which increases the contact area between the sealing cap 11 and the wire harness body 1, thereby increasing the friction and improving the stability of the installation of the sealing cap 11. The sealing cap 11 abuts against both ends of the wire harness body 1 through the rubber pad 13. At the same time, the tightening tape 14 is put on the wire core 2, which can improve the sealing effect at both ends of the wire harness body 1. The rubber protrusion 9 can lift the wire harness body 1, which can reduce the friction between the insulation outer layer 8 and the object when the wire harness body 1 is pulled, thereby improving the protection of the wire harness body 1. The heat dissipation groove 10 can improve the heat dissipation effect of the wire harness body 1. When the insulation outer layer 8 is broken, the rubber strip layer 7 expands when it comes into contact with water, which can seal the damaged area and improve the waterproofness of the wire harness body 1 during use.
