High voltage plug and receptacle

Claim 1

A two-part multiconductor high voltage electrical coupling comprising: a first coupling part having two parallel, spaced conductor terminals, an insulative body supporting the terminals and forming a socket around the terminals, and an insulative barrier wall extending from the body between the terminals; and a second coupling part having two spaced conductors mating with the terminals of the first part, an elastic, insulating support body for the conductors forming sleeves around the mating conductors respectively and a slot between the sleeves; the socket of the first coupling part being shaped to receive the support body of the second part with the barrier wall snugly fitting in the slot, and said support body and socket having opposed mating surfaces continuously diminishing in cross section into the socket so as to compress the elastic body laterally against the barrier wall thereby continuously to squeeze closed any air path along the barrier wall between spaced conductors, the coupling including spring means pressing endwise against the support body to maintain the squeeze of the elastic sleeve on the barrier wall.
