Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a rubber sheath of an automobile wiring harness. Background Art

[0002] Cars are large, with an average length of approximately four meters. They are composed of numerous integral components, including but not limited to airbags, ABS brakes, signal lights, and engines, among other key functional components. Automotive wiring harnesses are a crucial component of the vehicle's electrical network, connecting various electrical components and enabling power and signal transmission. To protect the wiring harness from environmental corrosion and mechanical damage, it is typically encased in a rubber sheath.

[0003] However, existing rubber sheaths have a relatively simple structure and fail to achieve both heat dissipation and high sealing performance. This results in difficulty dissipating heat at the wiring harness connection, which can easily affect the stability and safety of the wiring harness circuit. Furthermore, the installation and removal of traditional sheaths are cumbersome, increasing maintenance difficulty and cost. To address this issue, a rubber sheath for automotive wiring harnesses is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a rubber sheath for automobile wiring harness, which solves the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a rubber sheath for an automotive wiring harness, comprising a sheath body and a connecting mechanism, wherein both ends of the sheath body are fixedly connected with positioning rings, a clamping assembly is provided on the positioning ring, the connecting mechanism comprises a fixing ring, the inner wall of the fixing ring is fixedly connected with a tension spring, the end of the tension spring away from the fixing ring is fixedly connected with a docking ring, and the positioning ring is connected to the docking ring via a clamping structure.

[0006] Preferably, a groove is provided on the outer wall of the positioning ring, and the clamping assembly includes a compression spring fixedly connected to the inner wall of the groove, and a clamping block is fixedly connected to the end of the compression spring away from the groove. A clamping groove is provided on the outer wall of the docking ring, and a notch is provided on the outer wall of the docking ring and located on the outside of the clamping groove. The notch is connected to the clamping groove, and the clamping groove is clamped with the clamping block.

[0007] Preferably, the outer wall of the fixing ring abuts against the outer wall of the docking ring via a tension spring, and one end of the fixing ring away from the docking ring is fixedly connected to a connecting ring.

[0008] Preferably, the outer wall of the positioning ring is provided with heat dissipation holes, and the heat dissipation holes are wide outside and narrow inside.

[0009] Preferably, both ends of the sheath body are provided with limiting rings, the outer wall of the limiting ring is slidably connected to the inner wall of the sheath body, and the inner wall of the limiting ring is provided with a plurality of limiting sleeves.

[0010] Preferably, a limiting hole is provided on the inner wall of the positioning ring, and a limiting shaft is fixedly connected to the outer wall of the clamping block, and the limiting shaft is plugged into the limiting hole.

[0011] Compared with the related art, the automotive wiring harness rubber sheath provided by the present invention has the following beneficial effects:

[0012] 1. When in use, connect the connecting ring to the wiring port of the car body. When the connection between the two generates more heat, pull the sheath body to separate the connecting ring and the fixing ring, so as to dissipate the accumulated heat at the wiring terminal of the car harness. The operation is simple and convenient for timely heat dissipation. After the heat is dissipated, let go and stretch the spring to reset, so that the connecting ring and the fixing ring are tightly fitted again, so as to achieve rapid heat dissipation while maintaining sealing.

[0013] 2.

[0024] The outer wall of the positioning ring 1 is provided with a groove 12, and the clamping assembly includes a compression spring 13 fixedly connected to the inner wall of the groove 12. The end of the compression spring 13 away from the groove 12 is fixedly connected to a clamping block 14. The outer wall of the docking ring 2 is provided with a clamping groove 10, and the outer wall of the docking ring 2 and the outer side of the clamping groove 10 are provided with a notch 11. The notch 11 is connected to the clamping groove 10, and the clamping groove 10 is clamped with the clamping block 14. The outer wall of the fixing ring 3 and the outer wall of the docking ring 2 are abutted by the tension spring 8; when the positioning ring 1 is connected to the docking ring 2, the clamping block 14 is manually pressed to retract the clamping block 14 into the inside of the groove 12, and then the positioning ring 1 is inserted into the inside of the docking ring 2. After insertion, the positioning ring 1 is rotated to clamp the clamping block 14 in the clamping groove 10. The operation is simple, and the positioning ring 1 and the docking ring 2 can be quickly docked together, which is beneficial to the replacement and maintenance of the automobile wiring harness;

[0025] The outer wall of the positioning ring 1 is provided with a heat dissipation hole 7, which is wide outside and narrow inside. When the protective device is in normal use, the heat generated inside the positioning ring 1 can be dissipated in time through the heat dissipation hole 7, effectively avoiding heat accumulation. The heat dissipation hole 7 adopts a wide outside and narrow inside design, which prevents external water vapor from entering the interior of the positioning ring 1 while facilitating the heat dissipation of the positioning ring 1;

[0026] Both ends of the sheath body 4 are provided with a limit ring 5, the outer wall of the limit ring 5 is slidably connected to the inner wall of the sheath body 4, and the inner wall of the limit ring 5 is provided with a plurality of limit sleeves 6. After the automobile wiring harness is passed through the sheath body 4, the limit sleeves 6 on the inner side of the limit ring 5 are used to separate the wiring harness, thereby effectively avoiding the wiring harness from being scattered;

[0027] The inner wall of the positioning ring 1 is provided with a limiting hole, and the outer wall of the clamping block 14 is fixedly connected to the limiting shaft 15, which is plugged into the limiting hole. The clamping block 14 is limited by the limiting shaft 15, so that the clamping block 14 maintains high stability during the clamping process.

[0028] Working principle: When in use, connect the connecting ring 9 to the wiring port of the car body. When the connection between the two generates more heat, pull the sheath body 4 to separate the docking ring 2 and the fixing ring 3, so as to dissipate the accumulated heat of the car wiring harness terminal. The operation is simple and convenient for timely heat dissipation. After the heat is dissipated, let go and the stretch spring 8 will reset, so that the docking ring 2 and the fixing ring 3 will fit tightly together again, so as to achieve rapid heat dissipation while maintaining sealing. When connecting the positioning ring 1 to the docking ring 2, manually press the card block 14 to retract the card block 14 into the inside of the groove 12, and then insert the positioning ring 1 into the inside of the docking ring 2 After insertion, rotate the positioning ring 1 so that the clamping block 14 is clamped in the clamping slot 10. The operation is simple, and the positioning ring 1 and the docking ring 2 can be quickly docked together, which is beneficial for replacing and repairing the automobile wiring harness. When this protective equipment is in normal use, the heat generated inside the positioning ring 1 can be dissipated in time through the heat dissipation holes 7, effectively avoiding heat accumulation. The heat dissipation holes 7 adopt a wide outside and narrow inside design, which prevents external water vapor from entering the inside of the positioning ring 1 while facilitating the heat dissipation of the positioning ring 1. After the automobile wiring harness is passed through the sheath body 4, the wiring harness is separated by the limiting sleeve 6 on the inside of the limiting ring 5, effectively avoiding the wiring harness from being scattered.
