Universal serial bus with temperature sensing

Abstract

The invention provides a Universal Serial Bus (USB) device with improved structure. The USB device includes a housing, a circuit board, a temperature sensing assembly, a interface portion and a plurality of pins. The circuit board is positioned in the housing. The temperature sensing assembly is coupled to the circuit board. The interface portion, located on the end of the housing, includes an extended portion which extends to contact with the temperature sensing assembly. One end of a plurality of pins is coupled to the circuit board, and another end of pins is positioned on the inside of the interface portion, wherein the extended portion is used for transferring the temperature generated by the plurality of pins or the circuit board to the temperature sensing assembly. When the temperature reaches a default value, the temperature sensing assembly starts a breaking mechanism.

Description

technical field [0001] The invention relates to the structure of a universal serial bus (USB), in particular to a temperature-sensing USB. Background technique [0002] In the modern technological society, everyone wears at least one mobile phone, which is convenient for daily contact and information transmission. In order to maintain normal operation, maintaining the power of mobile phones is indispensable. Traditional mobile phones must use a specific charger to provide sufficient power, and the traditional charger and the wire (or charging cable) are integrally formed, one end of which can only be electrically coupled to the power plug, and the other end is coupled to a specific model of mobile phone through the wire; An additional transmission line is required to facilitate the information transmission between the mobile phone and another electronic device, thereby causing inconvenience for the user to carry. [0003] Recently, in order to improve the convenience of car...

Problems solved by technology

However, using micro-USB to transmit power may cause the temperature of micro-USB to be too high, so that the connection port will burn or leak electricity. The reason is that the small size of micro-USB and its internal structure cannot achieve effective heat dissipation or heat transfer. function, it is easy to cause the possibility of high temperature burning or even leakage

[0004] In order to solve the above-mentioned problem of heat dissipation, in the prior art, a conductive sheet / pad is added to conduct the heat energy generated by the circuit board or chip to the end of the micro-USB to reduce the temperature inside the micro-USB. However, The thermal conductivity of the conductive sheet / pad in the prior art is limited. If the conductive sheet / pad cannot quickly conduct heat energy to the end of the micro-USB, and the load capacity is limited, it may easily cause high temperature burnout
