Abstract
Abstract The invention is directed to an improved electrical connector having a calculably determinable number of suitably formed generally upstanding piercing members selectively disposed on at least one surface of a base member and selectively proportioned to provide a predetermined, sufficiently extensive area of contact between the conductor contacting portion of each piercing member and the conductive portion of an adjacently disposed insulated or noninsulated conductor.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
205 words
In an electrical connector of the type having a base member arranged to be disposed adjacent a conductor, and support means adjacent the base member and positionable about a conductor, for urging said base member in contact with a conductor the improvement comprising: a plurality of piercing members disposed on at least a portion of said base member and positionable adjacent the surface of a conductor; each of said piercing members having a first portion and a second portion, said first portion being disposed adjacent said base member and having a predetermined length selectively proportioned to bridge the space between the surface of said base member and the surface of a conductor adjacent thereto, said second portion being aligned substantially colinear with said first portion, extending therefrom, and having a predetermined length calculably selected to permit its entrance into and penetration of a conductor a predetermined depth in the range of from 5 to 45 percent of the minimum cross-sectional dimension of such conductor, said second portion being further defined by at least one surface comprising a predetermined conductor contact area, the aggregate conductor contact area of said plurality of second portions being at least equal to the cross-sectional area of the conductor engageable therewith.
Claim 2
Dependent Claim
205 words
In an electrical connector of the type having a base member arranged to be disposed adjacent a conductor, and support means adjacent the base member and positionable about a conductor, for urging said base member in contact with a conductor the improvement comprising: a plurality of piercing members disposed on at least a portion of said base member and positionable adjacent the surface of a conductor; each of said piercing members having a first portion and a second portion, said first portion being disposed adjacent said base member and having a predetermined length selectively proportioned to bridge the space between the surface of said base member and the surface of a conductor adjacent thereto, said second portion being aligned substantially colinear with said first portion, extending therefrom, and having a predetermined length calculably selected to permit its entrance into and penetration of a conductor a predetermined depth in the range of from 5 to 45 percent of the minimum cross-sectional dimension of such conductor, said second portion being further defined by at least one surface comprising a predetermined conductor contact area, the aggregate conductor contact area of said plurality of second portions being at least equal to the cross-sectional area of the conductor engageable therewith.
