Quick connect electrical plug

Claim 1

A quick-connect electrical plug for use with a two-conductor insulated cord said plug comprising: (A) first and second housing members, said housing members having groups of associated and opposed apertures, paired recesses and cavities to form an assembly; (a) a cord receiving slot, terminating at an outer surface of said plug; (b) first and second terminal receiving slots each disposed substantially perpendicularly to said cord receiving slot, said terminal receiving slots terminating at an outer surface of said plug; (c) first and second terminal retainer means within the interior of housing members, each retainer means being disposed adjacent to an associated one of said terminal receiving slots; (d) a spike-receiving recess in said cord receiving slot in said first housing disposed in line with the first of said terminal receiving slots and a spike-receiving recess in said cord receiving slot in said second housing disposed in line with said second terminal receiving slot; (e) a wedged-shaped recess in said cord receiving slot in said first housing disposed in line with said second terminal receiving slot and a wedge-shaped recess in said cord receiving slot in said second housing disposed in line with said first terminal receiving slot, and (B) first and second terminals for slideable reception in said first and second terminal receiving slots, each of said terminals comprising: (i) a short tine and a long tine joined together at adjacent ends thereof, said adjacent ends constituting a blade for insertion into a receptacle, said tines being urged apart at the opposite ends thereof by the inherent springiness of the material of which the contacts are made, the longer of said tines terminating with a first spike at said opposite end thereof, said spike being positioned to penetrate the insulation and conductor of one of said conductors in said cord and to enter said spike receiving recess, said longer tine also including a cable clamping portion adjacent said spike, said cable clamping portion being positioned to abut the insulation around the other of said conductors, and to deform said conductor into said associated wedge-shape recess, the shorter of said tines having an ear formed thereon, said ear abutting said terminal retaining means when the associated said terminal is slid outwardly of said housing members, the said short tine further including a resilient detent, said detent snapping behind said terminal retaining means when the said terminal is slid into insulation and conductor piercing relationship with the said cord, the said first and second terminals being permanently locked into the said first and second housing members after insertion of said first and second terminals.
