Abstract

The invention provides a printed circuit board and a mobile terminal. A first shielding cover is arranged above a first circuit, and a first gap is arranged at the first shielding cover; a second shielding cover is arranged above a second circuit, a second gap is arranged at the second shielding cover, and an insulation pressure board is arranged above a conversion circuit; the first gap and the second gap are oppositely arranged, and two ends of the insulation pressure board are respectively arranged the first gap and the second gap. High voltage electric shock can be effectively avoided when manual maintenance and circuit mounting are carried out, safety is improved, and manual operation safety can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a printed circuit board and a mobile terminal. Background technique [0002] In the prior art, components of a mobile terminal are integrated on a PCB (Printed Circuit Board, printed circuit board). When the maintenance personnel need to install or maintain the circuit, the signal transmission from the high-voltage circuit to the low-voltage circuit is required. Currently, there are no protective measures, so the maintenance personnel are likely to cause the danger of high-voltage electric shock. Contents of the invention [0003] Embodiments of the present invention provide a printed circuit board and a mobile terminal, which can effectively avoid the risk of high-voltage electric shock during manual maintenance and circuit installation, improve safety, and effectively ensure the safety of manual operation. [0004] An embodiment of the present invention provides a p...
