Description

A new waterproof structure

technical field

The invention belongs to the field of design and manufacture of daily necessities, and in particular relates to a novel waterproof structure.

Background technique

Current waterproof products, such as electronic products, generally can only achieve waterproof performance in ordinary environments, but it is difficult to achieve waterproof performance in severe environments such as high temperature, high pressure and low temperature. In order to achieve waterproof performance in these harsh environments, usually only The product body can be strengthened and enlarged to make it extremely bulky.

Developing a structure that is simple, lightweight and has a good waterproof effect is currently a difficult problem. For this reason, our R&D personnel have conducted a lot of research. Finally, by adding a simple buffer structure, the problem of waterproof seal failure in extreme environments can be solved.

Contents of the invention

The purpose of the present invention is to provide a novel waterproof structure, which can achieve ideal waterproof effect under harsh environment.

For realizing above object, technical scheme of the present invention is:

A new type of waterproof structure, including shell A and shell B, shell A and shell B are fastened to form a closed space for storing protected components, and the joint of shell A and shell B is provided with A sealing member for improving sealing performance; the shell part A is provided with a through hole, and an elastic deformation part is arranged around the inner surface of the shell part A.

The distance between the edge of the elastic deformation member and the through hole is 5-50mm.

1-10 conducting holes are provided on the shell member A, and the number of elastic deformation parts around the corresponding conducting holes is the same as the number of conducting holes.

1-10 conduction holes are provided on the shell member A, and 1 elastic deformation member is arranged around 1-5 conduction holes, and the number of elastic deformation members is 2-8.

The inner surface of the outer casing B is provided with a sealing groove for fixing the sealing element.

The shell part A and the shell part B are connected by a buckle.

The sealing member is any one of a waterproof rubber ring and a gasket.

The protected component is any one of PCB board, electronic component and electronic product

The beneficial effects of the present invention are:

1. The present invention adopts through-holes and sealed elastic parts, which can expand and contract with heat and contract the internal gas in extreme environments such as high temperature and high pressure, and balance the internal pressure through elastic deformation parts and through-holes, ensuring the stability tightness.

2. The structure of the present invention is simple, so that the elastic deformable part is protected from damage by external hard objects. By reducing the area of the conduction hole, the edge of one elastic deformable part covers multiple conduction holes, which effectively protects the elastic deformable part and prolongs the The life of the waterproof structure.
