Description

Binding post skeleton sealing washer

Technical Field

The utility model belongs to the field of new energy automobiles, and relates to a binding post framework sealing ring.

Background

With the development of the new energy automobile industry, the requirements of the whole automobile on water resistance, dust resistance, insulation and pressure resistance of key parts are gradually improved; the whole vehicle is required to ensure safe and reliable work, key parts must reach the protection level of IP67 and meet the voltage insulation and withstand requirements under the conditions of high voltage and large current, and a sealing ring is an indispensable part. The existing sealing structure in the market at present mostly uses O-shaped sealing rings for sealing, has simple structure and low price, and becomes one of sealing structure schemes, but because the O-shaped sealing sleeve has small compression amount, thin diameter and no strength as a whole, the O-shaped sealing sleeve needs to be assisted and fixed by other redundant structures, has poor waterproof effect, has high requirements on the processing precision of peripheral parts, and cannot play a role in insulation, pressure resistance and isolation. In order to solve the defects, the binding post framework sealing ring is designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a binding post framework sealing ring. In order to achieve the purpose, the utility model adopts the technical scheme that:

the binding post framework sealing ring consists of a metal framework (1), a dustproof lip (2), a sealing lip (3), a rubber sealing body (4) and a spring (5); when in use, the rubber sealing body (4) is pressed on the shell (6) in an interference manner, and naturally, the dustproof lip (2) and the sealing lip (3) are tightly attached to the binding post (8) by the elasticity of the rubber and the spring (5) arranged on the inner side of the sealing lip (3); the sealing device has the advantages of simple structure, convenience in assembly and good sealing performance after assembly.

A metal framework (3) is arranged in the binding post framework sealing ring (7), and the metal framework (3) can play a role in supporting the integral rigidity and strength of the sealing ring; closely laminating when can guaranteeing with casing (6) interference fit does not become invalid, and sealing member body intensity rigidity is good, makes sealed effect reach the best, does not rely on other unnecessary structures to assist fixed can accomplish the assembly when terminal skeleton sealing washer (7) assembles in addition, saves unnecessary structure, and is with low costs good reliability.

Terminal skeleton sealing washer (7), be provided with dustproof lip (2), sealed lip (3) twice lip simultaneously in the sealing washer inboard, dustproof lip (2) play sand prevention dirt-proof effect, sealed lip (3) can play waterproof grease proofing effect, twice seal structure is reliable and stable, has played the double seal effect, has increased protection safety and redundancy.

The dustproof lip (2), the sealing lip (3) and the rubber sealing body (4) of the terminal post framework sealing ring (7) are all made of rubber materials, and the rubber materials can achieve the effects of insulation, pressure resistance and elastic buffering; when the binding post (8) is used, large current and voltage can pass through the binding post, the shell (6) is made of metal conducting materials, and short circuit and electric arc are easily formed when the distance between the shell and the binding post is close; the dustproof lip (2), the sealing lip (3) and the rubber sealing body (4) of the terminal skeleton sealing ring (7) are made of rubber materials, so that the dustproof and waterproof effect can be achieved, and the insulating and pressure-resistant effect can be achieved.

Terminal skeleton sealing washer (7), there is spring (5) at its sealing lip (3) inboard, can give support and buffering when terminal (8) are not placed in the middle or terminal (8) swing along with cable (9), guarantee that sealing lip (3) and terminal (8) closely laminate, when guaranteeing follow-up use, reduce the friction and the impact of terminal skeleton sealing washer (7) and terminal (8), alleviate terminal (8) not hard up problem that other external forces lead to, improve product life.

Dustproof lip (2), the sealed lip (3) twice lip of terminal skeleton sealing washer (7), have from the centering function in cooperation terminal (8), can prevent that terminal (8) from becoming invalid at the eccentric product that leads to of assembling process, can avoid the installation stress damage product that leads to between two parties when terminal (8) assemble.

Detailed Description

The core of the utility model is a binding post skeleton sealing ring, which structurally comprises a metal skeleton (1), a dustproof lip (2), a sealing lip (3), a rubber sealing body (4) and a spring (5), and is characterized in that the rubber sealing body (4) is pressed on a shell (6) in an interference fit manner, and the dustproof lip (2) and the sealing lip (3) are tightly attached to a binding post (8) by the elasticity of rubber and the spring (5).

In the embodiment, the metal framework (3) is arranged in the binding post framework sealing ring (7) and plays a role in supporting the integral rigidity and strength of the sealing ring; can ensure that the tight fit does not fail when the sealing ring is in interference fit with the shell (6).

In this embodiment, be provided with dustproof lip (2), sealed lip (3) twice lip simultaneously in terminal skeleton sealing washer (7) inboard, can play dustproof waterproof dual sealed effect.

In the embodiment, the dustproof lip (2), the sealing lip (3) and the rubber sealing body (4) on the terminal skeleton sealing ring (7) are made of rubber materials, so that the effects of insulation, pressure resistance and buffering can be achieved.
