Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a protective cover for an insulating rubber and plastic sheath for automotive wiring harnesses. Background Technology

[0002] In automotive wiring harness systems, insulating rubber and plastic protective covers play crucial roles in insulation, dustproofing, moisture protection, and protection against mechanical damage. They are core components ensuring the reliability and safety of wiring harnesses. However, with the rapid development of automotive electronics and the increasing complexity of wiring harness structures, traditional protective covers are experiencing frequent problems. Firstly, their external structural strength is insufficient, making them prone to breakage when bent and unable to withstand vibrations and impacts during vehicle operation. Secondly, standardized specifications are difficult to adapt to diverse wiring harness connectors, significantly reducing sealing and protective effects. Furthermore, the use of clips or screws for fixing makes installation cumbersome, tool-dependent, and prone to loosening after repeated disassembly, resulting in low reusability and failing to meet the needs of efficient maintenance of automotive wiring harnesses. Utility Model Content

[0003] The main purpose of this utility model is to provide a protective cover for an insulating rubber and plastic sheath for automotive wiring harnesses, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A protective cover for an automotive wiring harness insulation rubber and plastic sheath includes a rubber and plastic protective cover shell. A threaded mounting hole is provided in the middle of the lower end of the rubber and plastic protective cover shell. A wire harness structure is provided in the threaded mounting hole. A main wire harness sleeve is fixedly connected to the middle of the upper end of the rubber and plastic protective cover shell. External reinforcement and anti-breakage components are fixedly connected to the upper and lower outer surfaces of the main wire harness sleeve. A sealing plug is inserted into the upper inner wall of the main wire harness sleeve. Three wire bodies are inserted into the main wire harness sleeve and the rubber and plastic protective cover shell together.

[0006] Preferably, the external reinforcement and anti-breakage component includes a thickened rubber disc ring, the inner wall of which is provided with a plurality of shock-absorbing corrugated grooves, and a plurality of reinforcing ribs are fixedly connected in a ring array on the inner wall of the thickened rubber disc ring, and two annular rubber rings are fixedly connected to the upper part of one end and the lower part of the other end of each of the reinforcing ribs away from the thickened rubber disc ring.

[0007] Preferably, the two sets of externally reinforced anti-breakage components are symmetrically distributed vertically, and the two sets of externally reinforced anti-breakage components are equally spaced apart. The thickened rubber disc is fixedly connected to the outer surface of the main cable bundle sleeve by a number of reinforcing ribs.

[0008] Preferably, the wire harness structure includes a threaded rubber pad, with three through-holes at the upper center of the threaded rubber pad, three latches on the outer surface of the threaded rubber pad, each latch communicating with the interior of one of the three wire harness holes, and an arc-shaped clamping plate fixedly connected to the side of each of the three wire harness holes that are close to each other. A hand-operated rotating ring is fixedly connected to the lower center of the threaded rubber pad.

[0009] Preferably, the threaded rubber pad body is movably connected to the upper inner thread of the rubber and plastic protective cover through a threaded mounting hole.

[0010] Preferably, the three wire harness holes are arranged in a ring array, and the hand-pulled rotating ring is located inside the threaded mounting hole.

[0011] Preferably, the sealing plug component includes an anti-blocking plug, the outer surface of which is fixedly connected with an anti-slip outer ring, and the upper middle part of the anti-blocking plug has three through holes, and the inner walls of the three through holes are all fixedly connected with foamed rubber buffer blocks.

[0012] Preferably, the anti-blocking plug is inserted into the upper part of the inner wall of the main cable bundle sleeve via the anti-slip outer ring.

[0013] Preferably, the three wire bodies are respectively engaged with the three wire-bearing holes through three bayonets, and the three wire bodies are respectively inserted into the three wire-through holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the thickened rubber disc ring, with its highly elastic material and thickened design, directly buffers external impacts and reduces the stress on the wiring harness. The anti-vibration corrugated grooves on the inner wall absorb energy through deformation during vibration, dispersing the vibration impact force like a spring and avoiding resonance damage. The reinforcing ribs are distributed in a ring array to provide rigid support for the rubber disc ring, preventing it from deforming or collapsing under long-term stress. At the same time, the stress is evenly transmitted to the main harness sleeve. The ring rubber ring further enhances the connection stability between components, ensuring that each component is stressed in coordination. Therefore, the two sets of externally reinforced anti-breakage components, which are symmetrically distributed at the top and bottom and equidistantly, can resist the vibration impact during vehicle operation from multiple dimensions, effectively preventing the main harness sleeve at the top of the protective cover from bending and breaking, and ensuring the long-term reliable operation of the automotive wiring harness system.

[0016] 2. In this utility model, the threaded rubber pad disc in the wire harness structure can be installed and fixed with the rubber and plastic protective cover by rotation, and with the arc-shaped clamping plate, it can flexibly fix wire harnesses of different diameters. The provided clamping slot facilitates wire harness positioning, and the hand-pulled rotating ring enables manual operation, improving installation efficiency. The anti-blocking plug of the resealing plug component is tightly inserted with the main wire harness sleeve by means of the anti-slip outer ring, and the foamed rubber buffer block in the wire hole tightly wraps the wire harness, enhancing the sealing performance. The combination of the two not only solves the problem that traditional protective covers are difficult to adapt to diverse wire harnesses, but also eliminates cumbersome fixing methods such as clips and screws, achieving quick disassembly and assembly, and is not easy to loosen after repeated use, meeting the needs of efficient maintenance of automotive wire harnesses.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A protective cover for automotive wiring harness insulation rubber and plastic sheath includes a rubber and plastic protective cover shell 1. A threaded mounting hole 2 is provided in the middle of the lower end of the rubber and plastic protective cover shell 1. A wire harness structure 3 is provided in the threaded mounting hole 2. A main wire harness sleeve 4 is fixedly connected to the middle of the upper end of the rubber and plastic protective cover shell 1. External reinforcement and anti-breakage components 6 are inserted and fixedly connected to the upper and lower outer surfaces of the main wire harness sleeve 4. A sealing plug component 7 is inserted into the upper inner wall of the main wire harness sleeve 4. Three wire bodies 5 are inserted into the main wire harness sleeve 4 and the rubber and plastic protective cover shell 1.

[0027] In this embodiment, the external reinforcement anti-breakage component 6 includes a thickened rubber disc 61. The inner wall of the thickened rubber disc 61 is provided with a plurality of anti-vibration corrugated grooves 63. A plurality of reinforcing ribs 62 are fixedly connected in a ring array on the inner wall of the thickened rubber disc 61. Two ring rubber rings 64 are fixedly connected to the upper part of one end and the lower part of the other end of the plurality of reinforcing ribs 62 away from the thickened rubber disc 61. The two sets of external reinforcement anti-breakage components 6 are symmetrically distributed vertically and equidistantly. The thickened rubber disc 61 is fixedly connected to the outer surface of the main cable bundle sleeve 4 through the plurality of reinforcing ribs 62.

[0028] Through the above solution, the external reinforcement anti-breakage component 6 solves the problems of easy breakage and poor vibration resistance of the protective cover by structural reinforcement and buffer energy absorption. The thickened rubber disc 61, with its increased thickness and rubber elasticity, forms a basic protective layer to directly resist external impacts. The anti-vibration corrugated groove 63 on the inner wall is similar to a spring structure, which absorbs energy through compression and rebound during vibration, reducing vibration transmission. The reinforcing ribs 62 are distributed in a ring array to provide a rigid support skeleton for the thickened rubber disc 61, disperse stress to avoid local concentration, and prevent excessive deformation. In addition, the ring rubber ring 64 further enhances the stability of the component connection and ensures that the overall structure is stressed together. The two sets of symmetrically distributed external reinforcement anti-breakage components 6 are fixed at equal intervals to the main cable sleeve 4, which can resist vibration impact from multiple directions, significantly improving the protective cover's breakage resistance and protection reliability.

[0029] In this embodiment, the wire harness structure 3 includes a threaded rubber pad body 31. Three through-holes 32 are provided at the upper center of the threaded rubber pad body 31. Three latches 34 are provided on the outer surface of the threaded rubber pad body 31, each communicating with the interior of one of the three wire harness holes 32. Arc-shaped retaining plates 33 are fixedly connected to the adjacent sides of each of the three wire harness holes 32. A hand-operated rotating ring 35 is fixedly connected to the lower center of the threaded rubber pad body 31. The threaded rubber pad body 31 is movably connected to the upper inner thread of the rubber and plastic protective cover 1 through threaded mounting holes 2. The three wire harness holes 3... 2 are arranged in a ring array. The hand-pulled rotating ring 35 is located in the threaded mounting hole 2. The sealing plug component 7 includes an anti-blocking plug 71. An anti-slip outer ring 74 is fixedly connected to the outer surface of the anti-blocking plug 71. Three through holes 73 are opened in the middle of the upper end of the anti-blocking plug 71. Foamed rubber buffer blocks 72 are fixedly connected to the inner walls of the three through holes 73. The anti-blocking plug 71 is inserted into the upper part of the inner wall of the main cable bundle 4 through the anti-slip outer ring 74. The three wire bodies 5 are respectively snapped into the three cable bundle holes 32 through the three bayonets 34. The three wire bodies 5 are respectively inserted into the three through holes 73.

[0030] Through the above solution, the wire harness structure 3 and the sealing plug component 7 solve the problems of compatibility and installation efficiency through adjustable tightening and tool-free insertion design. Specifically, the threaded rubber pad 31 is rotated and adjusted through the threaded mounting hole 2, which drives the arc-shaped clamping plate 33 in the wire harness hole 32 to clamp wires 5 of different diameters. The clamping slot 34 assists in the positioning of the wire harness. The ring array of wire harness holes 32 is adapted to the layout of multiple wire harnesses, realizing the compatibility of the standardized structure with diverse wire harnesses. The hand-pulled rotating ring 35 facilitates manual operation and can complete the installation and fixation without tools, improving efficiency. The anti-blocking plug 71 of the sealing plug component 7 is inserted into the main wire harness sleeve 4 through the anti-slip outer ring 74. The foamed rubber buffer block 72 in the wire hole 73 adaptively wraps the wire harness to enhance the sealing performance. The entire structure does not require clips or screws, can be quickly disassembled and assembled, and has a high reusability, effectively solving the drawbacks of traditional fixing methods and meeting the needs of efficient maintenance.

[0031] It should be noted that this utility model is a protective cover for an insulating rubber and plastic sheath for automotive wiring harnesses. During use, firstly, the wire body 5 is inserted into the wiring harness hole 32 through the latch 34. Rotating the hand-pulled rotating ring 35 causes the threaded rubber pad 31 to screw into the threaded mounting hole 2, causing the arc-shaped clamping plate 33 to tighten and fix wire bodies 5 of different diameters, achieving rapid wiring harness adaptation. Then, the anti-blocking plug 71 is inserted into the main wiring harness sleeve 4 through the anti-slip outer ring 74. The foamed rubber buffer block 72 inside the wire hole 73 wraps around the wire body 5, improving sealing. In the external reinforcement and anti-breakage component 6, the thickened rubber disc 61... The main harness sleeve 4 fits snugly against the body, the anti-vibration corrugated groove 63 absorbs vibration energy, the reinforcing rib 62 and the annular rubber ring 64 enhance structural rigidity, and the two sets of externally reinforced anti-breakage components 6 distributed symmetrically on the top and bottom resist impacts from all directions, preventing the main harness sleeve 4 fixed at the top of the protective cover from breaking. Therefore, the harness structure 3 achieves flexible adaptation and convenient installation of the harness, and the sealing plug component 7 strengthens the sealing protection. Combined with the externally reinforced anti-breakage components 6, the vibration resistance is improved, which effectively solves the problems of poor adaptability, cumbersome installation and easy breakage of traditional protective covers, and significantly improves the safety, reliability and maintenance efficiency of automotive harnesses.
