Electronic equipment and over-temperature protection system and method

Abstract

The invention discloses electronic equipment and an over-temperature protection system and method and aims to prevent a charging jack of the electronic equipment from being burned and improve safety of the electronic equipment. The electronic equipment comprises a processor, and a first temperature detection unit and a second temperature detection unit which are connected with the processor, wherein the first temperature detection unit is arranged at the charging jack of the electronic equipment and is used for detecting a present first temperature value of the charging jack and sending the first temperature value to the processor, the second temperature detection unit is arranged in the electronic equipment away from the charging jack and is used for detecting a present second temperature value of the external environment and sending the second temperature value to the processor, the processor is used for determining whether the first temperature value and the second temperature value are greater than a preset first threshold, if yes, the electronic equipment is controlled for over-temperature protection. The electronic equipment is advantaged in that the charging jack burning problem caused by heating of the electronic equipment can be prevented, and charging safety of the electronic equipment is improved.

Description

technical field [0001] The invention relates to the technical field of charging protection, in particular to an electronic device, an over-temperature protection system and a method. Background technique [0002] With the improvement of mobile terminal configuration, the power consumption of mobile terminals is getting higher and higher, so the requirements for charging equipment are also getting higher and higher. The charging device is connected with the mobile terminal through the charging connector, so as to charge the mobile terminal. Such as Figure 1A As shown, the charging methods of the mobile terminal include the following methods: 1. The power plug of the charging device obtains power from a conventional power socket, and the charging device uses conventional components to convert alternating current into direct current of a predetermined voltage, which is suitable for charging via conventional The charging connector charges the mobile terminal; 2. The power plug...

AI Technical Summary

Problems solved by technology

[0006] When the charging device is charging the mobile terminal through the charging connector, if there is a possibility or introduction of conductive foreign matter between the power shrapnel or grounding shrapnel of the charging connector and the power shrapnel or grounding shrapnel in the charging socket of the charging device, it is equivalent to An additional resistance is introduced between the shrapnel of the charging connector and the corresponding shrapnel in the charging socket of the charging device, which is equivalent to the increase of the contact impedance between the charging connector and the corresponding shrapnel in the charging socket of the charging device, so that the charging socket of the charging device The calorific value also increases sharply, and there is a hidden danger of burning

However, the area of ​​the shrapnel of the charging socket connector is small and the heat dissipation performance is poor. Therefore, when the contact impedance is abnormal, the risk of overheating and burning the charging socket is extremely high, which greatly reduces the safety of the charging device when charging.
