Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof components, and particularly relates to a rubber-plastic composite waterproof plug. Background Art

[0002] The waterproof plug is a plug made of elastomer (rubber). It is mainly used for waterproofing, dustproofing and electrode protection in equipment that is prone to water ingress. In the design of electronic wiring harnesses, it is mainly used for waterproofing the terminal insertion port of the waterproof sheath and preventing corrosion of the terminal by salt, etc. It can be divided into two categories: independent waterproof plugs and integrated waterproof plugs. During the use of the equipment, the equipment causes the wiring harness to vibrate, and the wiring harness and the waterproof plug will become loose, which can easily cause moisture to enter the wiring harness, affecting the waterproof effect of the waterproof plug, and there are safety hazards in the use of the wiring harness. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a rubber-plastic composite waterproof plug, which effectively solves the problem of poor waterproof effect.

[0004] The technical solution is to include a main body, a vertical harness hole is provided in the middle of the main body, fireproof cotton is wrapped around the inner circumference of the main body, a plurality of outer sealing rings are evenly fixed on the outer edge surface of the main body, a sealing groove is provided between two adjacent outer sealing rings, a plurality of clamping assemblies are evenly provided in the harness hole, the clamping assemblies include a first conical ring and a second conical ring, the end with the smallest diameter of the first conical ring is fixedly connected to the end with the smallest diameter of the second conical ring, the end with the largest diameter of the first conical ring and the end with the largest diameter of the second conical ring are respectively fixedly connected to the inner wall of the harness hole, and the first conical ring and the second conical ring are elastic components.

[0005] Preferably, a plurality of limiting grooves are provided on the lower surface of the main body.

[0006] Compared with traditional equipment, the utility model has the following advantages: 1) The structure is ingenious, and the first conical ring and the second conical ring structure are adopted, which can flexibly clamp the wire harness. Even if the wire harness vibrates, the wire harness can be well fixed in the wire harness hole, and the clamping effect is good, ensuring the waterproof performance. It is economical and practical, and at the same time ensures the structural integrity of the main body, prevents the main body from deformation, and facilitates the subsequent assembly of the main body and external components; 2) The fireproof cotton is adopted to further improve the fire resistance and high temperature resistance of the main body, can adapt to different environments, and improve the quality of the waterproof plug.

[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 3 A rubber-plastic composite waterproof plug is provided, comprising a main body 1, a vertical harness hole 2 is provided in the middle position of the main body 1, a fireproof cotton 3 is wound around the inner circumference of the main body 1, a plurality of outer sealing rings 4 are evenly fixed on the outer edge surface of the main body 1, a sealing groove 5 is provided between two adjacent outer sealing rings 4, a plurality of clamping assemblies are evenly provided in the harness hole 2, the clamping assemblies include a first conical ring 6 and a second conical ring 7, the smallest diameter end of the first conical ring 6 is fixedly connected to the smallest diameter end of the second conical ring 7, the largest diameter end of the first conical ring 6 and the largest diameter end of the second conical ring 7 are respectively fixedly connected to the inner wall of the harness hole 2, and the first conical ring 6 and the second conical ring 7 are elastic components.

[0013] A plurality of limiting grooves 8 are provided on the lower surface of the main body 1 .

[0014] When the utility model is in use, the wiring harness is inserted into the wiring harness hole 2, and the wiring harness passes through the clamping assembly. Under the joint action of the first conical ring 6 and the second conical ring 7, the smallest diameter end of the first conical ring 6 and the smallest diameter end of the second conical ring 7 clamp the wiring harness together. The first conical ring 6 and the second conical ring 7 are made of rubber material, have certain elasticity, good flexibility, and can clamp the wiring harness well. The first conical ring 6 and the second conical ring 7 are deformed in the wiring harness hole 2, which will not change the structure of the main body 1, and effectively prevent the main body 1 from deforming, which not only ensures the clamping effect of the wiring harness, improves the waterproof effect of the waterproof plug, but also ensures the integrity of the main body 1, and facilitates the subsequent installation of the main body 1. The inner circumference of the main body 1 is wrapped with fireproof cotton 3, which further ensures the fireproof and high temperature resistant effect of the main body 1. In addition, a plurality of limiting grooves 8 are provided on the lower surface of the main body 1. In the process of assembling the outer sealing ring 4 and the sealing groove 5 with external components, the staff can move the limiting groove 8 with their fingers to make the main body 1 rotate appropriately, which is conducive to better assembly of the outer sealing ring 4 and the sealing groove 5 with external components, and improves installation efficiency and installation quality.
