Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
217 words
A connector comprising: a connector jack and a connector plug for inserting into said jack to make electric connections therebetween, said jack comprising: a housing formed of insulating material and having a base and upstanding walls extending from said base to define an enclosed volume within said walls, said walls including a number of spaced projections extending therefrom to define body projections having surfaces in a plane substantially perpendicular to said base and body recesses having surfaces in a plane substantially perpendicular to said base between said projections which body recesses are recessed with respect to said body projections; and electrical contact elements placed on said body projections and said body recesses of said jack; said plug comprising: a housing formed of insulating material and having a base and a center portion upstanding from said base, said center portion including body recesses having surfaces in a plane substantially perpendicular to said base and body projections having surfaces in a plane substantially perpendicular to said base corresponding to said body projections and said body recesses of said jack for engagement therewith; and electrical contact elements placed on said plug body recess surfaces and said body projection surfaces of said plug for electrical connection with said contact elements of said jack when said plug and said jack are interconnected.
Claim 2
Dependent Claim
217 words
A connector comprising: a connector jack and a connector plug for inserting into said jack to make electric connections therebetween, said jack comprising: a housing formed of insulating material and having a base and upstanding walls extending from said base to define an enclosed volume within said walls, said walls including a number of spaced projections extending therefrom to define body projections having surfaces in a plane substantially perpendicular to said base and body recesses having surfaces in a plane substantially perpendicular to said base between said projections which body recesses are recessed with respect to said body projections; and electrical contact elements placed on said body projections and said body recesses of said jack; said plug comprising: a housing formed of insulating material and having a base and a center portion upstanding from said base, said center portion including body recesses having surfaces in a plane substantially perpendicular to said base and body projections having surfaces in a plane substantially perpendicular to said base corresponding to said body projections and said body recesses of said jack for engagement therewith; and electrical contact elements placed on said plug body recess surfaces and said body projection surfaces of said plug for electrical connection with said contact elements of said jack when said plug and said jack are interconnected.
Claim 3
Dependent Claim
41 words
A connector according to claim 1 wherein the distance said body projection surfaces of said jack project beyond said surfaces of said body recesses of said jack is more than 1.5 times the distance between adjacent body projections of said jack.
