Abstract
Abstract An improved tooth configuration for the contact surface of an electrical connector comprises a rearwardly sloping generally V-shaped upper surface peripherally circumscribed by upstanding side and rear walls communicating therewith along a sharp continuous edge. The apex of the V-shape is located at the communication of the obliquely disposed side walls and may have a height less than the height of the side walls at their distal ends. The teeth may be arranged in a series of parallel rows wherein the teeth in one row may be either similarly or oppositely oriented with respect to the teeth in an adjacent row.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
167 words
In an electrical connector of the type having a wire receiving portion having an interior surface, and a plurality of upstanding teeth disposed over said interior surface, the improvement comprising: each of said teeth having a generally V-shaped configuration in plan view, and comprising an upper surface circumscribed by a first side wall, a second side wall, and a rear wall, said upper surface communicating with said first and second side walls and said rear wall along a sharp edge, said first and second side walls being disposed generally normal to said interior surface and at an oblique angle with respect to one another, said first and second side walls communicating with one another along an edge defining the apex of said V-shape, said upper surface sloping downwardly from said apex to said rear wall and towards said interior surface, said upper surface having a generally concave curvature in a plan extending across said V-shape between the terminating ends of said first and said second side walls.
Claim 2
Dependent Claim
167 words
In an electrical connector of the type having a wire receiving portion having an interior surface, and a plurality of upstanding teeth disposed over said interior surface, the improvement comprising: each of said teeth having a generally V-shaped configuration in plan view, and comprising an upper surface circumscribed by a first side wall, a second side wall, and a rear wall, said upper surface communicating with said first and second side walls and said rear wall along a sharp edge, said first and second side walls being disposed generally normal to said interior surface and at an oblique angle with respect to one another, said first and second side walls communicating with one another along an edge defining the apex of said V-shape, said upper surface sloping downwardly from said apex to said rear wall and towards said interior surface, said upper surface having a generally concave curvature in a plan extending across said V-shape between the terminating ends of said first and said second side walls.
Claim 3
Dependent Claim
54 words
The improvement as defined in claim 1 wherein said upper surface has a generally concave curvature in two planes including a first plane extending from said apex of said V-shape towards said rear wall, and a second plane extending across said V-shape between the terminating ends of said first and said second side walls.
Claim 4
Dependent Claim
36 words
The improvement as defined in claim 1 wherein the height of said upper surface at said apex of said V-shape is lower than the height of said upper surface at the terminating ends of said V-shape.
Claim 5
Dependent Claim
20 words
The improvement as defined in claim 1 wherein each of said first and said second side walls is generally planar.
Claim 6
Dependent Claim
14 words
The improvement as defined in claim 1 wherein said rear wall is generally curvilinear.
Claim 7
Dependent Claim
39 words
The improvement as defined in claim 5 wherein each of said side walls is generally planar, and said upper surface has a generally concave curvature in a plane extending from said apex of said V-shape towards said rear wall.
Claim 8
Dependent Claim
44 words
The improvement as defined in claim 5 wherein each of said side walls is generally planar, and said upper surface has a generally concave curvature in a plane extending across said V-shape between the terminating ends of said first and said second side walls.
Claim 9
Dependent Claim
30 words
The improvement as defined in claim 7 wherein said upper surface has a generally concave curvature in a plane extending from said apex of said V-shape towards said rear wall.
