Signal-switching circuit, signal-switching method, and user equipment

Abstract

Embodiments of the present disclosure provide a signal-switching circuit, a signal-switching method, and a user equipment. The signal-switching circuit includes: a first electrical connector used for connecting with a second electrical connector, wherein the second electrical connector is used for providing a first group of signal terminals; a signal processing circuit used for providing a second group of signal terminals, wherein the first group of signal terminals is different from the second group of signal terminals, and the second electrical connector and the signal processing circuit are connected to different grounding points isolated from each other; a connection detection circuit used for detecting whether the first electrical connector is connected with the second electrical connector; and a control unit used for causing the signal processing circuit to stop transmitting signals with the second group of signal terminals in a case of detecting that the first electrical connector is connected with the second electrical connector; wherein the signal-switching circuit is configured to connect the first group of signal terminals or the second group of signal terminals to an electronic device. The signal-switching circuit of the present disclosure can realize signal switching at a low cost and prevent electromagnetic interference.
