Abstract

The invention provides an FPC (flexible printed circuit) board fixing method and a mobile terminal. The mobile terminal comprises a rear cover; a first PFC which is fixedly connected with the rear cover; a front cover which is provided with a battery accommodation groove, wherein a battery and the first FPC are separated by a gap when the battery is installed in the battery accommodation groove. When a charging loop comprising the first FPC is used for charging, the heat generated by the first FPC can be dissipated through the gap between the battery and the first FPC. The front cover cannot prevent the heat dissipation of the first FPC, and the overlapping effect of the temperature rise caused by the heating of the first FPC and the temperature rise caused by the heating of the battery is greatly weakened, thereby effectively reducing the internal temperature rise of the mobile terminal, and guaranteeing the charging efficiency and 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, 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 seriously ...
