Abstract

Provided are a charging device for a mobile terminal and a mobile terminal, wherein the mobile terminal comprises a main board. The charging device comprises a sub-board (10), wherein the sub-board (10) is connected to a main board and the sub-board (10) is located at a pre-set distance above the main board; and a charging circuit (20), wherein the charging circuit (20) is arranged on the sub-board (10) and the charging circuit (20) is used to charge a battery of a mobile terminal according to an input charging voltage. According to the charging device, interference between high and low voltage circuits can be prevented, and at the same time, the security of a high voltage can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a charging device for a mobile terminal and a mobile terminal. Background technique [0002] At present, the fast charging circuit of mobile terminals is generally set on the main board and designed on the printed circuit board PCB together with other circuits, so the high-voltage signal of the fast charging circuit and the low-voltage signal of other circuits are likely to cause interference. At the same time, the high-voltage flash charging circuit and the low-voltage circuit are together, and it is easy to touch the high-voltage circuit during installation and maintenance, causing danger. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention is to provide a charging device for a mobile terminal, which can avo...
