Mobile terminal

Abstract

The invention provides a mobile terminal. The mobile terminal comprises a machine shell, a flexible printed circuit board and a waterproof assembly; a groove used for accommodating the waterproof assembly is formed in the machine shell; the flexible printed circuit board connected with the waterproof assembly passes through the groove; the waterproof assembly comprises a support base and a fixed plate in connection; the support base is sleeved with a sealing ring, and the sealing ring is laminated to the side wall of the groove; a through hole is formed in the support base; a cutting groove isformed in the fixed plate; the flexible printed circuit board passes through the through hole via the cutting groove to be placed in an accommodating cavity defined by the through hole and the fixedplate; the flexible printed circuit board which passes through the cutting groove of the fixed plate is connected with the support base through the fixed plate, and interference assembling with the machine shell is realized through the sealing ring which is arranged on the outer edge of the support base in a sleeving manner; therefore, detachment and assembling between the flexible printed circuitboard and the machine shell, and maintenance and operation can be convenient; and the waterproof effect of the flexible printed circuit board can be jointly realized by the sealing ring, the supportbase and the fixed plate, so that the waterproof function of the flexible printed circuit board can be ensured effectively.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal. Background technique [0002] With the continuous development of mobile terminal technology, mobile terminals such as mobile phones have become indispensable electronic devices in people's lives. FPC flexible board (Flexible Printed Circuit Board, also known as flexible circuit board) is an important component for electrical signal transmission in mobile terminals. In order to improve the waterproof performance of mobile terminals, the waterproof effect of FPC flexible boards is usually realized in the following two ways: 1. Inject the rubber ring directly on the FPC flexible board, and perform interference assembly between the rubber ring on the FPC flexible board and the casing to achieve the waterproof effect on the FPC flexible board, but the production cost of this waterproof method is high, and The yield rate of directly injecting the ru...

FPC flexible board (Flexible Printed Circuit Board, also known as flexible circuit board) is an important component for electrical signal transmission in mobile terminals. In order to improve the waterproof performance of mobile terminals, the waterproof effect of FPC flexible boards is usually realized in the following two ways: 1. Inject the rubber ring directly on the FPC flexible board, and perform interference assembly between the rubber ring on the FPC flexible board and the casing to achieve the waterproof effect on the FPC flexible board, but the production cost of this waterproof method is high, and The yield rate of directly injecting the rubber ring on the FPC flexible board is low; 2. Do glue sealing on the FPC flexible board, but this waterproof method makes the FPC flexible board after dispensing and sealing difficult to disassemble, which affects the maintenance cost in the later period
