Mobile phone and waterproof press key panel thereof

Abstract

The invention discloses a mobile phone and a waterproof press key panel thereof. The waterproof press key panel comprises an upper case, a plastic press key and a rubber press key, wherein the upper case comprises a through hole which penetrates through the upper case, a first accommodating cavity and a second accommodating cavity are formed by the through hole, the plastic press key comprises an accommodating portion and a first press portion which upwards extends from the accommodating portion, the accommodating portion is inserted into the second accommodating cavity to enable a part of the first press portion to be accommodated in the first accommodating cavity, the rubber press key comprises a base portion, a connecting portion, a second press portion and an electric conduction substrate which are formed integrally, the connecting portion is connected with the base portion and the second press portion, the second press portion extends upwards relative to the base portion to form a protrusion, the electric conduction substrate extends downwards from the lower surface of the second press portion to form a protrusion, the base portion is in an interference fit with the second accommodating cavity wall to form a sealing connection, and the second press portion is inserted into the accommodating portion and fixedly abutted to the accommodating portion. The mobile phone and the waterproof press key panel thereof have the advantages that the waterproof purpose is achieved by utilizing a separated type press key structure, the waterproof effect of the mobile phone and the waterproof press key panel is good, the structure is simple, the assembling is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a mobile phone and a waterproof key panel thereof. Background technique [0002] At present, with the continuous development of wireless communication and electronic information technology, the application range of mobile phones is becoming more and more extensive, and people's requirements for mobile phones are also getting higher and higher. They must not only be beautiful and powerful, but also be able to adapt to various harsh environments , the entire market and customers have higher and higher requirements for the waterproof performance of mobile phones, and the waterproof design of mobile phones is already very important. [0003] However, it is relatively simple to realize waterproofing of the fixed parts inside the mobile phone, but it is more difficult to realize waterproofing of movable parts (such as buttons). The usual mobile phone keys genera...

Problems solved by technology

In order to ensure the feel of the button, there must be a gap between the button and the mobile phone case, the button and the button shrapnel (DOME sheet) / button circuit board. Water flow can easily enter the button shrapnel on the button circuit board, resulting in no function of the button

[0004] Therefore, it is necessary to provide a mobile phone and its waterproof button panel, to solve the problem that the buttons made of plastic and rubber in the prior art cannot be waterproofed
