Description

Technical Field

[0001] The utility model relates to the technical field of wire harness protection, in particular to a rubber sheath for automobile wire harness. Background Art

[0002] The automotive wiring harness is an important part of the automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then plastic-pressed with an insulator or an additional metal shell. During the use of the automotive wiring harness, it is often necessary to use a rubber sheath for protection. The rubber sheath is a wire sheath made of rubber. The product is stuck on the metal plate and the wire is passed through the middle. Its purpose is to protect the wire from being cut by the metal plate.

[0003] For example, Chinese patent authorization announcement number CN 215498098 U discloses a rubber protective cover for automotive wiring harnesses, including a protective cover body with an annular cross-section, a plurality of first clamping parts fixed in the protective cover, the first clamping parts are evenly spaced along the circumference of the protective cover body, the first clamping part is provided with a first clamping groove for clamping the wiring harness, and the first clamping groove is arranged along the length direction of the protective cover body; a support shaft is provided in the protective cover body, a second clamping part corresponding to the first clamping part is fixed in the circumference of the support shaft, a second clamping groove is provided on the second clamping part, the opening of the first clamping groove is arranged opposite to the opening of the second clamping groove, the first clamping part and the second clamping part abut to form a wiring harness channel, a slide bar is provided on the first clamping part, the slide bar is arranged along the length direction of the first clamping part, the second clamping part is provided with a slide groove corresponding to the slide bar, and the slide bar cooperates with the corresponding slide groove; the utility model can regularly arrange multiple wiring harnesses in the protective cover body, and the wiring harnesses are arranged at intervals to avoid problems such as aging and adhesion of the wiring harnesses.

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies: although the cables in the wiring harness can be separated one by one by the cooperation of the first clamping portion and the second clamping portion, the first clamping portion and the second clamping portion need to be combined together by clamping. Since there are a large number of cables in the wiring harness, the cables are separated by clamping the first clamping portion and the second clamping portion each time, and the operation steps are relatively cumbersome. Moreover, when the wiring harness is long, if the length of the rubber sleeve body is not enough, it is difficult to combine multiple rubber sleeve bodies together to protect the wiring harness, resulting in poor applicability of the rubber sleeve body. Utility Model Content

[0005] The utility model provides a rubber sheath for an automobile wiring harness, which is conducive to more conveniently separating cables in the wiring harness one by one and is conducive to improving the applicability of the rubber sheath body.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An automobile wiring harness rubber sheath comprises a rubber sheath body;

[0010] The rubber sleeve body consists of a waterproof layer, a corrosion-resistant layer and a flame-retardant layer.

[0011] Furthermore, the rubber stopper is made of silicone rubber.

[0015] Furthermore, the corrosion-resistant layer is connected to the inner wall of the waterproof layer, and the flame-retardant layer is connected to the inner wall of the corrosion-resistant layer.

[0016] Beneficial effects of the utility model:

[0017] 1.

[0027] The rubber sleeve body 1, the fixing sleeve 2, the internal thread connection sleeve 3, the docking sleeve 4, the external thread connection sleeve 5, the sealing ring 7, the branching block 8, the branching groove 9, the rubber stopper 10, the waterproof layer 11, the corrosion-resistant layer 12, and the flame-retardant layer 13. DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] like Figure 1-3 As shown, in this embodiment, it includes a rubber sleeve body 1, the upper and lower ends of the rubber sleeve body 1 are connected to a fixed sleeve 2, the inner wall of the fixed sleeve 2 is connected to a plurality of branching blocks 8, the inner side of the branching blocks 8 is provided with branching grooves 9, the edges of the inner walls of the branching grooves 9 on both sides are connected to rubber stoppers 10, the rubber stoppers 10 are made of silicone rubber, and the spacing between the two rubber stoppers 10 in the same branching groove 9 is 0.5-1 mm.

[0030] When the wiring harness is protected by the rubber sheath, after the wiring harness passes through the rubber sheath body 1, the cables in the harness extend into the fixed sheath 2, and then the cables in the wiring harness are pulled one by one to move into the branching groove 9. During this process, the cables will squeeze the rubber stopper 10 made of silicone rubber. Since the spacing between the two rubber stoppers 10 in the same branching groove is 0.5-1 mm, under the premise of setting the spacing to 0.6 mm, the rubber stopper 10 will be elastically deformed after the cable squeezes the rubber stopper 10, so that the cable can be conveniently inserted into the branching groove 9 through the gap between the two rubber stoppers 10, and then through the elastic reset performance of the rubber stopper 10, the rubber stopper 10 will block the cable in the branching groove 9, so as to conveniently separate the cables one by one, which is beneficial to avoid the situation where the cables in the wiring harness are entangled with each other. Compared with the prior art, the operation of separating and arranging the cables in the wiring harness in the rubber sheath body 1 is simpler.

[0031] like Figure 5 , 6 As shown, in this embodiment, the lower end of the fixing sleeve 2 is connected with an internal threaded connecting sleeve 3, and the upper end of the fixing sleeve 2 is provided with a sealing connection assembly, and the sealing connection assembly includes a docking sleeve 4, an external threaded connecting sleeve 5 and a sealing ring 7. The docking sleeve 4 is connected to the upper end of the fixing sleeve 2, and the external threaded connecting sleeve 5 is connected to the upper end of the docking sleeve 4. The external threaded connecting sleeve 5 is threadably matched with the internal threaded connecting sleeve 3.

[0032] When the wiring harness is long and the length of a single rubber sleeve body 1 is not enough, two or more rubber sleeve bodies 1 need to be combined. At this time, the internal threaded connecting sleeve 3 and the external threaded connecting sleeve 5 are threadedly connected, which is conducive to combining multiple rubber sleeve bodies 1 together for use, thereby facilitating the protection of wiring harnesses of different lengths, and effectively improving the applicability of the rubber sleeve body 1.

[0033] like Figure 5 , 6 As shown, in this embodiment, the upper end of the butt sleeve 4 is connected with a sealing ring 7 sleeved on the outside of the external threaded connection sleeve 5, and the outer diameters of the butt sleeve 4 and the internal threaded connection sleeve 3 are equal.

[0034] Moreover, when the internal threaded connecting sleeve 3 is connected to the external threaded connecting sleeve 5, the internal threaded connecting sleeve 3 will be pressed tightly on the sealing ring 7. The sealing performance of the sealing ring 7 will help to improve the sealing performance of the connection between the internal threaded connecting sleeve 3 and the external threaded connecting sleeve 5, effectively preventing water from entering the rubber sleeve body 1 through the connection, and thus achieving better protection for the wiring harness.

[0035] like Figure 4As shown, in this embodiment, the rubber sleeve body 1 is composed of a waterproof layer 11, a corrosion-resistant layer 12 and a flame-retardant layer 13. The corrosion-resistant layer 12 is connected to the inner wall of the waterproof layer 11, and the flame-retardant layer 13 is connected to the inner wall of the corrosion-resistant layer 12.

[0036] Since the rubber sleeve body 1 is composed of a waterproof layer 11, a corrosion-resistant layer 12 and a flame-retardant layer 13, the waterproof layer 11 is made of styrene-butadiene rubber with good waterproof performance, and the corrosion-resistant layer 12 is made of fluororubber with good corrosion resistance and aging resistance, and the flame-retardant layer 13 is made of chloroprene rubber with good heat resistance. In summary, the rubber sleeve body 1 has good waterproof, corrosion-resistant and flame-retardant properties, which effectively improves the protection performance of the wiring harness.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
