Abstract

The invention provides a method for fixing a flexible circuit board (FPC) and a mobile terminal. The mobile terminal includes: a rear cover; a first FPC fixedly connected to the rear cover; a front case with a battery accommodating groove, and when a battery is installed in the battery accommodating groove, there is a gap between the battery and the first FPC. When using the charging circuit including the first FPC to charge the battery, the heat generated by the first FPC can be dissipated through the gap between the battery and the first FPC. The superposition effect of temperature rise generated by the heat generation is greatly weakened, which can effectively reduce the temperature rise inside the mobile terminal, thereby ensuring the charging efficiency and charging safety of the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an FPC fixing method and a mobile terminal. Background technique [0002] At present, in order to realize the charging of the battery, the inside of the mobile terminal is generally connected by a flexible printed circuit (FPC). Specifically, such as figure 1 As shown, the mobile terminal includes a first FPC2 and a front case 3 , and when a battery 4 is installed in the mobile terminal, the first FPC2 is interposed between the front case 3 and the battery 4 . When using the charging circuit including the first FPC2 to charge the battery 4, especially when charging with a large current, since the front case 3 hinders the heat dissipation of the first FPC2, the heat generated by the first FPC2 and the heat generated by the battery 4 are prone to superposition of temperature rise In this way, the temperature rise effect inside the mobile terminal is very significant, which serio...
