Abstract: An electric base, an electric gateway, and an electric gateway body are presented. The electric base includes: an electric base body, where two guide holes for passing cables in an electric grid are arranged in the electric base body, an output end for outputting a voltage of the cables is arranged on the electric base body and protrudes from the electric base body, and a conductor structure is nested in the electric base body to connect the cables and the output end. The foregoing electric base can be electrically connected to an input end of the electric gateway body and output power to enable the electric gateway body to operate.

Abstract: The present invention provides a multipurpose connector for multiplexing a headset interface into a high-definition video/audio input interface and a handheld device including the multipurpose connector. The multipurpose connector includes a headset connector, a selecting switch, a high-definition video/audio transceiver, and an audio output module. The headset connector includes a first audio terminal and a second audio terminal. The audio output module is configured to output an audio signal of the headset. The selecting switch includes first and second lines. When the selecting switch communicates with the first line, the first audio terminal and the second audio terminal are coupled to a pair of differential transmission lines respectively, and the pair of differential transmission lines is configured to transmit high-definition video/audio data output by the high-definition video/audio transceiver.
