Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
268 words
An electrical connector for applying energy to an electrical device comprising a receptacle and cooperating adaptor plug, said receptacle including a body of insulating material, a pair of spaced openings in one surface of said body, electrical connecting means disposed within said openings and an electric cable connected within said body to said electrical connecting means and extending from said body for connection to a power source and said adaptor plug including a body of material, a pair of pins extending from one surface of the last said body for mating with the electrical connecting means in said receptacle, a cylindrical dual contactor plug extending from another surface of said body and means within the last said body connecting each of said pins to one of the contactors of the last said plug, the surfaces of the body of said adapter plug being disposed at about 90° one relative to the other and said cylindrical dual contactor plug comprising an outer sleeve forming one contactor, a centrally disposed rod insulated from said sleeve and carrying the other contactor, the inner end of said sleeve having a lug portion extending at 90° thereto and a tubular insulating member having a diameter at least equal to the diameter of said sleeve and a section of reduced diameter disposed within said sleeve, a second lug having a circular portion overlying the outer end of said insulator and a portion extending therefrom, said rod extending through said insulator and second lug and swaged to secure it in position and said pins being coplanar with and electrically coupled to said extending lug portions.
