[0002] Automotive wiring harness sleeves are primarily used for the protection of wiring harnesses in critical components of automobiles. They are an essential part of the automotive wiring harness system, mainly used to protect the wiring harnesses from external environmental influences and ensure their normal operation. Wiring harness sleeves are typically made of various materials, including plastics, rubber, and metals. Their main functions are to provide mechanical protection, electrical insulation, and environmental protection. The structural design and material selection of the wiring harness sleeve directly affect the performance and service life of the wiring harness.

[0003] Traditional sleeves lack sufficient internal tightness, allowing the wire harness to move easily inside, affecting stability. They also have relatively low strength and are easily damaged. In addition, the sleeves are not wear-resistant, and their smooth surfaces are prone to wear, resulting in multiple shortcomings. Utility Model Content

[0006] Preferably, the extrusion structure includes a surface hose with multiple extrusion balls attached to its surface. The extrusion balls extrude the anti-slip texture to limit the extrusion of the automotive wiring harness inside the surface hose.

[0007] Preferably, the surface of the outer tube is formed into a convex surface by the compression of the extrusion ball.

[0008] Preferably, the extrusion structure further includes anti-slip textures disposed on the inner wall of the surface hose, the anti-slip textures being used to increase friction;

[0009] A limiting ring is fitted onto the surface hose, and the inner side of the limiting ring is connected to the apex of the end of the extrusion ball away from the surface hose.

[0010] Preferably, the sleeve body is composed of a surface layer, an outer layer, a middle layer, and an inner layer;

[0011] The surface layer is bonded to the outer wall inside the surface layer by adhesive;

[0012] The inner layer is bonded to the inner wall of the surface layer with adhesive.

[0013] The inner layer is disposed between the outer layer and the middle layer and is bonded together with adhesive.

[0014] Preferably, the limiting ring is disposed in the middle of the outer layer, and the outer circle of the limiting ring is fixed to the outer wall inside the surface layer;

[0015] The extrusion balls move within the surface layer, outer layer, middle layer, and inner layer, are arranged in a ring, and are made of an elastic material.

[0016] The two ends of the surface hose are glued to the inner ring surface of the sleeve body.

[0018] Preferably, the outer layer is made of aluminum foil corrugated material;

[0019] The intermediate layer is made of silicone glass fiber material;

[0020] The inner layer is filled with sponge adhesive.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) In this utility model, the extrusion balls apply radial pressure to the surface hose through a ring arrangement to form a convex surface, which makes the wire harness fit tightly and reduces displacement. The anti-slip texture on the inner wall increases friction, further suppresses the rotation or sliding of the wire harness, provides rigid support, prevents excessive deformation of the extrusion balls from causing pressure failure, and at the same time distributes the extrusion pressure evenly to avoid local stress concentration.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] Please see Figure 1 - Figure 3 This application provides a wiring harness sleeve for automobiles, including: a sleeve body 1, and a compression structure 2 for compressing and stabilizing the sleeve inside the sleeve body 1.

[0031] In this embodiment, preferably, the extrusion structure 2 includes a surface hose 200, and a plurality of extrusion balls 204 are attached to the surface of the surface hose 200. The extrusion balls 204 extrude the anti-slip texture 202 to achieve extrusion and limiting of the automotive wiring harness inside the surface hose 200.

[0032] In this embodiment, preferably, the surface of the outer flexible tube 200 is formed into a convex surface 203 by the extrusion of the extrusion ball 204.

[0033] It should be noted that when the surface of the outer flexible tube 200 is formed into a convex surface 203 by the extrusion ball 204, the surface of the convex surface 203 also extrudes the internal wire harness, making the wire harnesses more compact.

[0034] The material of the surface hose 200 is a soft material, which is prone to deformation when the surface hose 200 is squeezed.

[0035] In this embodiment, preferably, the extrusion structure 2 further includes anti-slip texture 202 disposed on the inner wall of the surface hose 200, the anti-slip texture 202 being used to increase friction.

[0036] The limiting ring 201 is sleeved on the surface hose 200, and the inner side of the limiting ring 201 is connected to the apex of the end of the extrusion ball 204 away from the surface hose 200.

[0037] It should be noted that the anti-slip texture 202 increases the friction inside the surface hose 200, which reduces the rotation of the wire harness inside the surface hose 200 and improves stability.

[0038] The limiting ring 201 is made of metal and can provide support for the limiting ring 201.

[0039] During implementation, the wire harness is passed through the outer flexible tube 200, and the outer flexible tube 200 is compressed by the compression ball 204 to form a convex surface 203 to tighten the wire harness.

[0044] The inner layer 104 is disposed between the outer layer 102 and the middle layer 103 and is bonded together by adhesive.

[0045] In this embodiment, preferably, the limiting ring 201 is disposed in the middle of the outer layer 102, and the outer circle of the limiting ring 201 is fixed to the outer wall inside the surface layer 101;

[0046] The extruded balls 204 are movable in the surface layer 101, the outer layer 102, the middle layer 103, and the inner layer 104. The extruded balls 204 are arranged in a ring and are made of elastic material.

[0047] The two ends of the surface hose 200 are glued to the inner ring surface of the sleeve body 1.

[0048] In this embodiment, preferably, the surface layer 101 is composed of TPV material and is formed by extrusion.

[0049] It should be noted that the surface layer 101 is more specifically made of 251-80W232 material;

[0050] After the TPV 251-80W232 material was extruded, a voltage withstand test was conducted on the product as required: voltage 2kV, time 60s; test result: no breakdown at 2kV.

[0051] After extrusion, the TPV 251-80W232 material underwent a voltage withstand test as required: a voltage increase of 500V / s, with air as the medium; test result: no breakdown at 5kV.

[0052] After extrusion, the TPV 251-80W232 material underwent a high-temperature pressure test as required: test temperature (100±2)℃, duration 4h, coefficient 0.6, load 2.50±0.03N; test results: indentation depth ≤50%;

[0053] After the TPV 251-80W232 material was extruded, an aging test was conducted on the product according to requirements: the test temperature was 150℃, the test time was 168h, and the product could not come into contact with metal during the test; the test results showed that the product cross-section did not delaminate after the test, and the product did not crack after aging.

[0055] The intermediate layer 103 is made of silicone glass fiber material;

[0056] The inner layer 104 is filled with sponge adhesive.

[0057] During implementation, the outer layer 102 is made of aluminum foil corrugated tubing material, which gives the sleeve body 1 high mechanical strength and can effectively protect the wire harness from external damage. At the same time, the aluminum foil corrugated tubing is lightweight and will not increase the burden on the car.

[0058] The intermediate layer 103 is made of silicone glass fiber material, which gives the sleeve body 1 excellent insulation performance, effectively prevents current leakage, and ensures the electrical safety of the wire harness. At the same time, silicone glass fiber provides excellent fire protection to prevent fire from spreading to the wire harness.

[0059] The inner layer 104 is filled with sponge adhesive, which gives the sleeve body 1 excellent buffering performance, effectively absorbing vibration and impact, protecting the wire harness from damage, and can also elastically cooperate with the extrusion ball 204.
