Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness waterproofing and relates to a wire harness waterproofing rubber structure. Background Art

[0002] Rubber parts are used for waterproofing inside cars. They have excellent waterproof effects and protect wiring harnesses from damage. They are widely used in waterproofing of cars and other products. There are many types of rubber parts for waterproofing wiring harnesses, but the current structural design of waterproof rubber parts is too backward. When waterproof sealing is performed, the waterproof performance is poor, which causes external rainwater to easily enter the equipment through the wiring harness hole and the rubber seat. At the same time, the outer clamping groove of the rubber seat is only clamped and installed by rubber elastic force. When the rubber ages, it is easy to cause a decrease in elasticity, which in turn causes unstable installation. These problems need to be improved. Summary of the invention

[0003] The utility model aims to provide a wiring harness waterproof rubber structure to solve the problems raised in the above background technology.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a wiring harness waterproof rubber structure, including a rubber seat, a clamping groove, and a wiring harness hole, the outer wall surface of the rubber seat is provided with a clamping groove, and the interior of the clamping groove is provided with a plurality of evenly arranged metal spring sheets, the interior of the rubber seat is provided with an inner waterproof component, the inner waterproof component is composed of a plastic sheet and a waterproof inner seat, and the waterproof inner seat is arranged at the center position of the plastic sheet, and the side of the plastic sheet is fixedly connected to the inner wall surface of the rubber seat.

[0005] In the above-mentioned harness waterproof rubber structure, an inner groove is opened inside the rubber seat, and the inner waterproof component is arranged inside the inner groove. A conical waterproof end surface is arranged at the side position of the bottom end of the rubber seat. The setting of the conical waterproof end surface can make the bottom end of the rubber seat fit more closely with the inner wall of the mounting hole of the rubber seat when it is installed, thereby preventing leakage caused by fine gaps.

[0006] In the above-mentioned harness waterproof rubber structure, a harness hole is provided at the center of the bottom end of the rubber seat, and the harness hole is communicated with the inside of the inner groove.

[0007] In the above-mentioned harness waterproof rubber structure, a waterproof cavity is opened inside the waterproof inner seat, and a waterproof guide platform is arranged at the bottom of the waterproof cavity. The waterproof guide platform is arranged obliquely to prevent rainwater entering the waterproof cavity from flowing out again, thereby flowing into the equipment through the rubber seat.

[0008] In the above harness waterproof rubber structure, an upper port is opened at the top center of the waterproof inner seat, a lower port is opened at the bottom center of the waterproof inner seat, and both the upper port and the lower port are connected to the inside of the waterproof cavity.

[0009] Compared with the prior art, the advantages of the wiring harness waterproof rubber structure of the utility model are:

[0010] The present application arranges a metal spring sheet on the outside of the clamping groove of the traditional rubber seat, so that the rubber seat is not easy to loosen when it is clamped and installed through the clamping groove, and the installation stability is high, which avoids the problem of rubber aging. At the same time, a waterproof inner seat is also arranged inside the rubber seat, and a waterproof cavity is arranged inside the waterproof inner seat. When external rainwater enters the inner groove through the wiring harness hole, it can also be blocked by the internal waterproof component. After passing through the wiring harness hole, the wiring harness passes through the upper port and the lower port in turn. In this way, even if rainwater enters the inner groove and the waterproof cavity, the rainwater can be blocked inside the waterproof cavity by the conical waterproof guide platform, thereby avoiding rainwater from damaging the equipment after passing through the internal waterproof component.

The interior of the rubber seat 1 is provided with an inner waterproof component 6, and the inner waterproof component 6 is composed of a plastic sheet 8 and a waterproof inner seat 7, and the waterproof inner seat 7 is arranged at the center position of the plastic sheet 8, and the side of the plastic sheet 8 is fixedly connected to the inner wall surface of the rubber seat 1.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the wire harness waterproof rubber structure of the present invention, specifically, an inner groove 13 is opened inside the rubber seat 1, and the inner waterproof member 6 is arranged inside the inner groove 13.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the wire harness waterproof rubber structure of the present invention, specifically, a wire harness hole 5 is provided at the center of the bottom end of the rubber seat 1, and the wire harness hole 5 is connected to the inside of the inner groove 13, and the wire harness hole 5 is opened according to the inner diameter of the wire harness.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model wire harness waterproof rubber structure, specifically, the interior of the waterproof inner seat 7 is provided with a waterproof cavity 9, and the bottom of the waterproof cavity 9 is provided with a waterproof guide platform 10. The waterproof cavity 9 of the present application is mainly used to intercept rainwater entering the interior of the waterproof inner seat 7, and the rainwater blocked in the waterproof cavity 9 can evaporate naturally after the temperature rises on sunny days, and no special treatment is required.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model wire harness waterproof rubber structure, specifically, an upper port 11 is opened at the center position of the top end of the waterproof inner seat 7, and a lower port 12 is opened at the center position of the bottom end of the waterproof inner seat 7, and the upper port 11 and the lower port 12 are both connected to the interior of the waterproof cavity 9.
