Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically to a rubber sealing ring for cab wiring harnesses. Background Technology

[0002] The cab wiring harness is a crucial component of a vehicle, and its sealing performance directly impacts the vehicle's sound insulation, dustproofing, and waterproofing capabilities. The performance of the rubber seals on the cab wiring harness directly affects the reliability of the vehicle's electrical system, requiring a comprehensive design that considers material properties, structural innovation, and operational conditions. Through precise interference fit design, multi-lip sealing structures, and the selection of weather-resistant materials, seal life and safety can be effectively improved, meeting the increasingly stringent waterproofing and aging resistance requirements of the automotive industry.

[0003] A prior art patent with publication number CN216215704U discloses a solution comprising a rubber sealing ring body, a door panel, and an auxiliary fixing mechanism. The rubber sealing ring body has a compression cavity, and multiple evenly distributed holes are drilled on the side wall of the compression cavity. The door panel is located on one side of the rubber sealing ring body, and a wire harness hole is drilled on the door panel. A wire harness tube connects a pair of rubber sealing ring bodies. The auxiliary fixing mechanism is located within the compression cavity and includes a telescopic rod. One end of the telescopic rod is inserted into the compression cavity, and the other end of the telescopic rod outside the compression cavity is connected to a fixing ball. By setting the corresponding mechanism for the wire harness rubber sealing ring, the fixing effect of the rubber sealing ring is increased, making it less likely to fall off during and after installation, thus reducing the protection of the wire harness, increasing the service life of the wire harness, and reducing unnecessary losses for the user.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, when using existing sealing rings, the wire harness holes cannot meet the fixing requirements of wire harnesses of different diameters due to the different diameters of the wire harnesses.

[0006] Secondly, existing sealing rings are limited by their fixing structure, making it impossible to quickly and securely install them with the cab mounting holes, thus reducing assembly efficiency.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the shortcomings of the prior art, this utility model solves the problem that when the sealing ring of the traditional technology is used, the wire harness hole cannot meet the fixing requirements of wire harnesses of different diameters.

[0009] To solve the above problems, this utility model provides the following technical solution:

[0010] A rubber sealing ring for cab wiring harnesses includes a rubber sealing ring body, on which are provided a fixed wiring harness hole and a variable wiring harness hole, and the variable wiring harness hole is surrounded by a plurality of sealing lips.

[0011] The outer peripheral wall of the rubber sealing ring body is surrounded by an installation groove, and the rubber sealing ring body forms two sealing skeletons through the areas on both sides of the installation groove.

[0012] As an optimized solution, the rubber sealing ring body is rectangular in shape.

[0013] As an optimized solution, the fixed wire harness holes and the variable wire harness holes are provided in a plurality of numbers and arranged in a straight line.

[0014] As an optimized solution, the rubber sealing ring body has an inner groove, and the fixed wire harness hole and the variable wire harness hole are formed on the inner groove.

[0015] As an optimized solution, the outer wall length and width of one of the sealing skeletons are greater than the outer wall length and width of the other sealing skeleton.

[0016] As an optimized solution, the sealing skeleton is surrounded by an arc-shaped guide outer wall.

[0017] As an optimized solution, the large-diameter ends of the arc-shaped guide outer walls of the two sealing skeletons are arranged opposite each other.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The rubber sealing ring body has an installation groove on its outer peripheral wall. The installation groove is used to snap into the installation hole in the cab. The sealing skeletons on both sides can lock the rubber sealing ring body into the installation hole to prevent it from falling out. The two sealing skeletons have different outer diameters, so the orientation of the rubber sealing ring body can be selected according to the direction of force on the wire harness. It is also convenient and quick to use the sealing skeleton with the smaller diameter to snap into the installation hole in the cab. Furthermore, the large diameter ends of the arc-shaped guide outer wall are set opposite each other, which makes it easier for the sealing skeleton to pass through the installation hole in the cab, improving the fixing efficiency of the rubber sealing ring body.

[0020] The variable wire harness hole has several sealing lips inside, which are used to fit tightly with the wire harness, so as to fix and support wire harnesses of different diameters.

[0021] By using fixed wire harness holes, wire harnesses with the same diameter as the fixed wire harness holes can be fixed. Since most of the wire harnesses in the cab are of the same diameter, setting fixed wire harness holes can reduce costs and improve assembly efficiency. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] like Figures 1 to 4 As shown, the rubber sealing ring for the cab wiring harness includes a rubber sealing ring body 1. The rubber sealing ring body 1 has a fixed wiring harness hole 6 and a variable wiring harness hole 5. The variable wiring harness hole 5 is surrounded by a plurality of sealing lips 7.

[0030] The outer peripheral wall of the rubber sealing ring body 1 is provided with an installation groove 3, and the rubber sealing ring body 1 forms two sealing skeletons 4 through the areas on both sides of the installation groove 3.

[0031] The rubber sealing ring body 1 is rectangular in shape.

[0032] Several fixed wire harness holes 6 and variable wire harness holes 5 are provided and arranged in a straight line.

[0033] The rubber sealing ring body 1 has an inner groove 2, and the fixed wire harness hole 6 and the variable wire harness hole 5 are opened on the inner groove 2.

[0034] The outer wall length and width of one of the sealing skeletons 4 are greater than the outer wall length and width of the other sealing skeleton 4.

[0035] The sealed skeleton 4 is surrounded by an arc-shaped guide outer wall 8.

[0036] The large-diameter ends of the arc-shaped guide outer walls 8 of the two sealing skeletons 4 are arranged opposite each other.

[0037] The rubber sealing ring body 1 is made of a blend of ethylene propylene diene monomer (EPDM) rubber and fluororubber (FKM), wherein the weight percentage of EPDM is 60%-80% and the weight percentage of FKM is 20%-40%.

[0038] With excellent aging resistance, the blended rubber of EPDM and FKM has excellent resistance to high temperature, low temperature, ozone, and ultraviolet radiation, which can effectively extend the service life of the sealing ring.

[0039] With excellent oil resistance, FKM rubber can effectively resist the erosion of oily substances such as engine oil and lubricating oil, ensuring sealing performance.

[0040] The sealing lip 7 design allows it to fit tightly against the wiring harness, effectively preventing water, dust, and other foreign objects from entering the cab.

[0041] The working principle of this device is as follows:

[0042] The rubber sealing ring body 1 is surrounded by an installation groove 3 on its outer peripheral wall. The installation groove 3 is used to snap into the installation hole in the cab. The sealing skeletons 4 on both sides can lock the rubber sealing ring body 1 into the installation hole to prevent it from falling out. The two sealing skeletons 4 have different outer diameters, so the orientation of the rubber sealing ring body 1 can be selected according to the direction of force on the wire harness. It is also convenient and quick to use the smaller diameter sealing skeleton 4 to snap into the installation hole in the cab. Furthermore, the large diameter ends of the arc-shaped guide outer wall 8 are set opposite each other, which makes it easier for the sealing skeleton 4 to pass through the installation hole in the cab and improves the fixing efficiency of the rubber sealing ring body 1.

[0043] The variable wire harness hole 5 has several sealing lips 7 inside, which are used to fit tightly with the wire harness, so as to fix and support wire harnesses of different diameters.

[0044] The wire harness is fixed by fixing the wire harness hole 6. Since most of the wire harnesses in the cab are of the same diameter, setting the wire harness hole 6 can reduce costs and improve assembly efficiency.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
