Abstract

The invention discloses a key structure and a portable mobile terminal, relating to the technical field of electronics. The invention solves the technical problem of larger size of the inside diameter of a through hole in the traditional key structure. The key structure comprises a key cap, a through hole, a rubber cushion and a key switch, wherein the through hole is arranged on a casing; the rubber cushion is fixedly provided with a pressing protrusion; the key switch is opposite to the pressing protrusion, the through hole and the key cap; the key cap is made from elastic materials, and isarranged on a port of the through hole far away from the key switch; and the pressure is applied to the key cap at one side of the key cap far away from the key switch in a direction close to the keyswitch, the pressure can make the key cap deformed along the axial direction of the through hole, and the pressing protrusion is driven by the deformed key cap to press the key switch. The portable mobile terminal comprises a casing, a circuit board and the key structure disclosed in the invention, and the key structure is a key structure of an on-hook key and / or a key structure of a dialing key.The invention is applied to electronic equipment provided with the key.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a key structure and a portable mobile terminal provided with the key structure. Background technique [0002] With the continuous development of electronic technology, portable mobile terminals such as mobile phones and PDAs have become the most common communication tools in people's daily lives. [0003] At present, users have higher and higher requirements for the appearance and performance of portable mobile terminals. The larger the size of the buttons, the more convenient for users to operate. Therefore, portable mobile terminals equipped with large-sized buttons are more and more popular with customers. [0004] The existing key structure includes a key cap, a through hole opened on the casing, a rubber pad fixedly provided with a pressing protrusion (or conductive base), and a key switch, of which: [0005] The key switch is opposite to the position of the pressing protr...
