Male connector for non-arcing electrical coupling

Abstract:

A non-arcing electrical coupling including a male connecter including an electrically conductive prong extending from an electrically insulating base member, the prong covered with an arc-mitigating coating formed of a resilient quantum tunneling compound, wherein the arc-mitigating coating exhibits a first electrical resistance when in an uncompressed state and exhibits a second electrical resistance when in a compressed state, the first electrical resistance greater than the second electrical resistance, and a female connecter including an electrically insulating base member defining a receptacle adapted to receive the prong of the male connecter, the receptacle containing an electrically conductive clip comprising a pair of electrically conductive tines adapted to compress at least a portion of the arc-mitigating coating when the prong is inserted into the receptacle.
