Problems solved by technology

[0002] Mobile terminals such as mobile phones and tablet computers have become necessities in people's daily life, but on the other hand, the proportion of repairs caused by water ingress in mobile terminals is increasing
The circuit board of the main board is short-circuited after the mobile terminal enters the water, thus damaging the circuit board and circuit components
Circuit boards and circuit components damaged by short circuits cannot be repaired, and need to be replaced with a new motherboard, which is very expensive to repair
[0003] The waterproofing of mobile terminals mainly adopts mechanical waterproofing, that is, increasing the sealing degree of mobile terminals, and using materials with high-quality waterproof performance to make the shell, but the manufacturing cost is high and the process is complicated
After a long time of use, as the mobile terminal shell wears and creates gaps, it may also cause short circuits due to water ingress
If the mobile terminal is placed in a place with high water vapor, the water vapor will condense in the gap and gradually penetrate into the mobile terminal, which may also cause a short circuit

Abstract

The invention discloses a circuit protection method which comprises the steps of obtaining a detection signal which is output by a moisture detection device, wherein the moisture detection device is located at the input and output joint; judging whether the detection signal exceeds a trigger threshold value; when the condition that the detection exceeds the trigger threshold value is judged, triggering an outage control signal to a power source control device. According to the circuit protection method, an external circuit is enabled to stop working due to outage and is prevented from being short-circuited to damage a circuit board and circuit elements due to water entrance under an electriferous working state. The invention also discloses a device for realizing the method and terminal equipment.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to a circuit protection method, device and terminal equipment. Background technique [0002] Mobile terminals such as mobile phones and tablet computers have become necessities in people's daily life, but on the other hand, the proportion of repairs caused by water ingress in mobile terminals is increasing. After the mobile terminal enters the water, the circuit board of the main board is short-circuited, thereby damaging the circuit board and circuit components. Circuit boards and circuit components damaged by a short circuit cannot be repaired, and need to be replaced with a new motherboard, and the repair cost is very high. [0003] The waterproofing of mobile terminals mainly adopts mechanical waterproofing, that is, increasing the sealing degree of mobile terminals, and using materials with high-quality waterproof performance to make the shell, but th...
