Waterproof plug structure and waterproof mobile phone using the structure

Abstract

The invention relates to a waterproof plug structure. The waterproof plug structure comprises a front shell, a waterproof plug and a rear shell. The waterproof plug comprises a hard rubber body which is provided with a supporting part. The waterproof plug further comprises a soft rubber layer, wherein the soft rubber layer is wrapped on the outer surface of the supporting part, and the soft rubber layer and the supporting part are integrally formed. The waterproof plug further comprises an elastic connector. The rear shell is provided with a blind groove. The elastic connector is movably clamped in the blind groove of the rear shell in a matched mode and is further connected with the front shell and the rear shell through assembly of the front shell and the rear shell, and meanwhile the soft rubber layer and the front shell are assembled in an interference fit mode. The waterproof plug is formed by the hard rubber body, the soft rubber layer and the elastic connector in a three-shot molding mode; since the soft rubber layer is arranged on the outer surface of the supporting part, when the soft rubber layer and a shell body are in assembly interference, the soft rubber layer bears uniform pressure from the two sides of the shell body and the supporting part and form uniform deformation, and the waterproofness is reliable.

Description

Technical field [0001] The invention relates to a waterproof plug structure and a waterproof mobile phone using the structure. Background technique [0002] In the waterproof design of various electronic devices, such as waterproof mobile phones, it is usually necessary to consider the waterproofing of various external interfaces, such as USB holes, charging holes, headphone jacks, etc. For the waterproofing of such interface positions, one can generally be used. The movable waterproof plug is sealed and waterproof.

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a waterproof plug structure, which can solve the problem of waterproof failure caused by the waterproof plug in the prior art that is difficult to restore after being deformed by multiple stresses, and the waterproof plug structure The waterproof plug is connected to the through-hole of the rear shell through the connecting rod, and there is one more waterproof level, which increases the difficulty of waterproofing, and at the same time solves the problem of assembly caused by the need for an additional shearing process after the waterproof plug is assembled in the prior art. The problem of inefficiency

[0005] Another technical problem to be solved by the present invention is to provide a waterproof mobile phone using the above-mentioned waterproof plug structure. The problem of low assembly efficiency due to the shearing process
