Problems solved by technology

[0002] The existing data lines generally have the functions of charging and data transmission. Since the existing data lines do not have an over-temperature protection function, when the operating temperature of the charging device and the data line is too high, it will affect data transmission and damage the data line and its connection. equipment, especially when the user leaves during the charging process or when the user sleeps and puts the mobile phone next to charge at night, the safety accidents will be immeasurable

Abstract

The invention provides a data line with a temperature over-temperature protection function. The data line comprises a USB 3.0 connector. The USB 3.0 connector is provided with a first pin, a second pin, a third pin and a fourth pin which are arranged side by side. An IC chip, a first resistor and a temperature acquisition chip are connected in series on the fourth pin. The temperature acquisitionchip is used for acquiring the working temperature of the USB3.0 connector and outputting the induced voltage to the IC chip according to the working temperature. The IC chip is used for comparing theworking temperature of the USB3.0 connector with the preset temperature threshold, and the IC chip automatically turns off power when the working temperature exceeds the preset temperature threshold.The temperature acquisition chip with small volume and high temperature sensitivity is used, and the power supply can be automatically cut off when the working temperature is too high in case of normal use so that the equipment can be effectively protected from being damaged and the power supply of the USB3.0 connector can be stopped.

Description

technical field [0001] The invention relates to the field of data lines, in particular to a data line with a temperature over-temperature protection function. Background technique [0002] The existing data lines generally have the functions of charging and data transmission. Since the existing data lines do not have an over-temperature protection function, when the operating temperature of the charging device and the data line is too high, it will affect data transmission and damage the data line and its connection. Equipment, especially when the user leaves during the charging process or when the user sleeps and puts the mobile phone next to charge at night, the occurrence of safety accidents will be immeasurable. Contents of the invention [0003] In order to solve the above shortcomings of the prior art, the purpose of the present invention is to provide a data line with a function of temperature over-temperature protection, so as to overcome the defects in the prior a...
