Technical Field

[0001] This utility model relates to the field of wire harness sheath technology, specifically an environmentally friendly lightweight wire harness sheath assembly. Background Technology

[0002] With the development of modern technology, electronic devices are increasingly widely used in various industries. As a crucial component connecting various electrical elements, the safety and stability of wiring harnesses are of paramount importance. In the field of engineering vehicles, wiring harnesses, as an essential part of the electrical system, undertake the critical task of connecting and transmitting power and signals. Engineering vehicles typically operate in harsh environments, such as high temperatures, low temperatures, humidity, dust, and strong vibrations, which places higher demands on the protection of wiring harnesses.

[0003] Traditional wire harness sheaths often reveal some shortcomings when facing these challenges. Due to the wide variety of wire harnesses used in engineering vehicles with different diameters, traditional fixed-size sheaths are difficult to adapt to this diversity, resulting in inconvenient installation or poor protective effect. Engineering vehicles generate significant vibrations during driving and operation, and ordinary sheaths cannot effectively fix the wire harnesses, causing the wire harnesses to shake inside the protective sheath, which may lead to wear or even breakage of the wires inside the wire harness. Therefore, an environmentally friendly and lightweight wire harness sheath assembly is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly and lightweight wire harness sheath assembly, which has the advantages of high adjustability, excellent shock resistance and environmental adaptability, and solves the problems of traditional sheaths being unable to adapt to wire harnesses of different diameters and being unable to be firmly fixed, resulting in wear and breakage of the wires inside the wire harness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly lightweight wire harness sheath assembly, including a protective strip body, a movable fixed anchor inside the protective strip body, and a locking bolt at the bottom of the protective strip body for adjusting the height of the fixed anchor; The main body of the protective strip includes a protective layer, a structural layer, and a honeycomb buffer layer. The honeycomb buffer layer is filled inside the side wall of the structural layer, and the protective layer covers the outer end face of the structural layer. A wire mounting port is provided at the center of the upper end face of the main body of the protective strip. The fixing anchor includes a lifting rod and an elastic anchor claw. The elastic anchor claw is fixedly installed on the upper end face of the fixing strip, and the lifting rod is movably installed on the upper end face of the bottom of the main body of the protective strip.

[0006] Furthermore, the bottom of the protective strip body is evenly provided with sliding grooves that slide and connect with the lifting rod. The bottom of the sliding groove is provided with a shaft hole. The locking bolt is installed in the shaft hole and rotates and connects with the protective strip body. The bottom of the lifting rod is provided with a screw hole that mates with the locking bolt. The bottom of the locking bolt is provided with an internal hexagonal hole.

[0007] Furthermore, the upper surface of the elastic anchor claw has an arc-shaped structure, and the elastic anchor claw is made of silicone material.

[0008] Furthermore, the bottom of the elastic anchor claw is provided with anti-slip ridges, and an air cavity is provided inside the elastic anchor claw.

[0009] Furthermore, the protective layer is made of polylactic acid.

[0010] Furthermore, the honeycomb buffer layer is made of EVA plastic foam.

[0011] Furthermore, the upper surface of the protective strip body is coated with self-adhesive, and the protective sleeve is provided with release paper for protecting the self-adhesive.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a linkage design of fixed anchor and locking bolt. The lifting rod of the fixed anchor achieves stepless height adjustment through the sliding groove and the threaded engagement of the locking bolt, thereby accurately clamping wire harnesses of different diameters and preventing the wire harness from swinging and rubbing inside the protective strip, which would cause damage to the outer sheath. The elastic anchor claw is made of silicone material and has a built-in air cavity, which not only ensures the flexibility during clamping to prevent damage to the insulation layer, but also guides the wire harness to slide into the fixed position through its arc-shaped upper end surface and is combined with the bottom anti-slip convex strip to enhance frictional resistance and prevent slippage. The honeycomb buffer layer further absorbs external vibration energy, forming multiple protections and significantly improving the durability of the wire harness under complex working conditions.

[0013] 2. This utility model uses biodegradable polylactic acid material for the protective layer, which has high mechanical strength, high temperature resistance and corrosion resistance, thus solving the pollution problem of traditional plastics; the structural layer is filled with EVA foam honeycomb buffer layer, which, through its lightweight, elastic, shockproof and flame-retardant characteristics, significantly reduces the overall weight while ensuring buffering performance, meeting the requirements of lightweighting. The combination of the two enables the sheath assembly to achieve the dual goals of environmental friendliness and energy saving and material reduction while maintaining high protective performance.

Detailed Implementation

[0016] Please see Figures 1-6 An environmentally friendly lightweight wire harness sheath assembly includes a protective strip body 1, a movable fixed anchor 2 inside the protective strip body 1, and a locking bolt 3 at the bottom of the protective strip body 1 for adjusting the height of the fixed anchor 2. The protective strip body 1 includes a protective layer 101, a structural layer 102, and a honeycomb buffer layer 103. The honeycomb buffer layer 103 is filled in the side wall of the structural layer 102. The protective layer 101 covers the outer end face of the structural layer 102. A wire mounting port 105 is provided at the center of the upper end face of the protective strip body 1. The fixed anchor 2 includes a lifting rod 201 and an elastic anchor claw 202. The elastic anchor claw 202 is fixedly installed on the upper end face of the fixed strip, and the lifting rod 201 is movably installed on the bottom upper end face of the protective strip body 1.

[0017] Furthermore, the bottom of the protective strip body 1 is evenly provided with sliding grooves 106 that are slidably connected to the lifting rod 201. The bottom of the sliding groove 106 is provided with shaft holes 107. The locking bolts 3 are installed in the shaft holes 107 and are rotatably connected to the protective strip body 1. The bottom of the lifting rod 201 is provided with screw holes 2011 that cooperate with the locking bolts 3. The bottom of the locking bolts 3 is provided with internal hexagonal holes 301.

[0018] By turning the locking bolt 3 clockwise with an Allen wrench, the lifting rod 201 slides down along the slide groove 106, thereby causing the fixing anchor 2 to slowly press and fix the wire harness, preventing the wire harness from swinging and rubbing against the protective strip body 1 during use, which would cause the wire harness skin to wear and crack.

[0019] Furthermore, the upper surface of the elastic anchor claw 202 is an arc-shaped structure, and the elastic anchor claw 202 is made of silicone material.

[0020] The curved elastic anchor claw 202 allows the wire harness to slide down from the upper end of the elastic anchor claw 202 to the lower end of the elastic anchor claw 202 after being inserted into the wire insertion port 105. This facilitates the elastic anchor claw 202 to press and fix the wire harness. The silicone elastic anchor claw 202 structure will not damage the insulation layer on the surface of the wire harness. On the other hand, during the pressing process, its edge can extend to both sides as the pressing depth increases, keeping it in contact with the bottom of the inner end face of the protective strip.

[0021] Furthermore, the bottom of the elastic anchor claw 202 is provided with anti-slip protrusions 2022, and an air cavity 2021 is provided inside the elastic anchor claw 202.

[0022] The anti-slip ridge 2022 increases the frictional resistance between the wire harness and the elastic anchor claw 202, thereby reducing the probability of the wire harness slipping. By setting an air cavity 2021 inside the elastic anchor claw 202, the elasticity of the elastic anchor claw 202 can be reduced, and the weight of the equipment can be reduced at the same time.

[0023] Furthermore, the protective layer 101 is made of polylactic acid.

[0024] The protective layer made of polylactic acid (PLA) has high mechanical strength, good high temperature resistance and corrosion resistance, and PLA is a biodegradable and environmentally friendly material.

[0025] Furthermore, the honeycomb buffer layer 103 is made of EVA plastic foam.

[0026] EVA is a lightweight and elastic material with good shock absorption, as well as some flame retardant and corrosion resistant properties. It can also greatly reduce the weight of the protective case and improve its lightweight design.

[0027] Furthermore, the upper surface of the protective strip body 1 is coated with self-adhesive, and the protective sleeve is provided with release paper 104 for protecting the self-adhesive.

[0028] The adhesive backing is protected by release paper 104. After peeling off the release paper 104, the protective cover can be quickly pasted onto the surface of the equipment, improving the convenience and stability of the protective cover installation.

[0029] When using this wire harness protective sleeve, first prepare the wire harness and corresponding equipment to be protected, ensuring that the surface of the wire harness and equipment is clean and free of oil, dust, and other debris. Also prepare an Allen wrench of the appropriate size to match the hexagonal hole 301 at the bottom of the locking bolt 3 for adjusting the height of the fixing anchor 2. Next, place the protective strip body 1 in a suitable position. Then, insert the wire harness into the wire insertion port 105 of the protective strip body 1. Utilize the arc-shaped structure of the upper end face of the elastic anchor claw 202 to allow the wire harness to slide down along its upper end face to the lower end, ensuring that the number of wire harnesses on both sides of the lifting rod 201 is approximately the same. Because the elastic anchor claw 202 is made of silicone, it will not damage the insulation layer on the surface of the wire harness. Then, take the Allen wrench, insert it into the hexagonal hole 301 at the bottom of the locking bolt 3, and rotate it clockwise to move the lifting rod 201 along the sliding groove 1. 06 Slide downwards to move the fixed anchor 2 down as a whole. The elastic anchor claw 202 gradually presses the wire harness. During this process, the anti-slip protrusion 2022 at the bottom of the elastic anchor claw 202 increases the frictional resistance between the elastic anchor claw 202 and the wire harness, reducing the probability of the wire harness slipping. The degree of pressing of the elastic anchor claw 202 on the wire harness is precisely controlled by adjusting the locking bolt 3 to prevent the wire harness from swinging and rubbing against the protective strip, which would cause the outer skin to wear and crack. Finally, observe the upper surface of the protective sleeve and find the part coated with self-adhesive and covered with release paper 104. Carefully peel off the release paper 104, being careful to prevent dust and other debris from adhering. Align the upper surface of the protective sleeve with the peeled release paper 104 with the equipment surface and press it steadily. The adhesive of the self-adhesive is used to make the protective sleeve easy to install. When pressing, ensure that the protective sleeve is tightly attached to the equipment surface to avoid air bubbles or gaps and improve the installation stability.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
