Abstract: The present disclosure discloses a USB data cable and a control method thereof. The said USB data cable used to extend a Type-C USB interface, comprising: a primary port configured to connect an external first device; a configuration channel module connected to the said primary port; multiple secondary ports configured to connect multiple external second devices; and multiple switch modules connected respectively to the said multiple secondary ports, wherein the said primary port is connected to the said multiple secondary ports via the said multiple switch modules through a USB bus, and the said configuration channel module is connected to the said multiple switch modules through an independent bus, so as to configure the said multiple secondary ports via the said switch modules.

Abstract: The present disclosure provides a mobile terminal and a heat sink thereof. The heat sink includes a first heat-conducting medium filled in a gap between a processor and a processor shield, a second heat-conducting medium filled in a gap between an electronic component and an electronic component shield and a third heat-conducting medium filled in a gap between the electronic component shield and a middle frame; the processor is disposed on one side, facing towards a rear casing, of a printed circuit board; heat dissipated from the processor is dissipated by a first heat dissipating channel composed of the first heat-conducting medium, the processor shield and the rear casing; heat dissipated from the processor is dissipated by a second heat dissipating channel composed of the printed circuit board, the second heat-conducting medium, the electronic component shield, the third heat-conducting medium and the middle metal frame.

Abstract: An embodiment of the present disclosure provides a mobile terminal and a middle frame thereof The middle frame of the mobile terminal includes a middle frame body in which a plurality of heat dissipating conduits are provided in a hollowing manner, the heat dissipating conduits are filled with a heat-conducting medium to absorb heat dissipated from individual functional modules in the mobile terminal. By means of the mobile terminal and the middle frame thereof provided by the embodiment of the present disclosure, in a case where the thickness of the mobile terminal is not increased, heat dissipated from individual functional modules may be absorbed by filling the heat-conducting medium in the heat dissipating conduits to dissipate heat from the individual functional modules, a heat dissipating demand of the individual functional modules is satisfied, and working of the individual functional modules at a normal temperature is guaranteed.
