Electrical connector plugs and socket assemblies with resistance and spark protection

Abstract

An electrical connector plug and socket assembly with resistance and spark protection includes: an electrical connector plug and an electrical socket. The electrical connector plug includes a plug housing having a main slot and a secondary slot; a main plug terminal having an insulating ring, a metal ring, and a metal tube; a resistor; a secondary plug terminal; and a plug socket having a main wire conduit, a secondary wire conduit, and a top abutment post. The plug socket assembly is assembled to the plug housing. In the assembled state, the main wire conduit abuts against the main plug terminal, the secondary wire conduit abuts against the secondary plug terminal, and the top abutment post abuts against the resistor, thereby confining the main plug terminal, the secondary plug terminal, and the resistor within the plug housing and preventing them from dislodging.
