DIRECT CURRENT PLUG, DIRECT CURRENT SOCKET, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2019/042096

A1

A direct current plug, a direct current socket and an electronic device. The direct current plug comprises a plug base (1) and an insertion part that is arranged on the plug base (1) and that is used for being inserted into a direct current socket; the insertion part comprises an anode insertion part and a cathode insertion part, at least one from among the anode insertion part and the cathode insertion part being a combined structure insertion part; the combined structure insertion part comprises an insertion part resistance section and an insertion part conductor section, the insertion part resistance section and the plug base (1) being arranged at intervals, while the insertion part conductor section is located between the insertion part resistance section and the plug base (1). The direct current plug may enable the insertion part resistance section to access a loop when the direct current plug is plugged in and unplugged so as to limit current, while also causing the insertion part resistance section to short circuit after the direct current plug is completely inserted into the direct current socket so as to cut out the loop without influencing the normal operation of an electronic device.
