Abstract
Abstract An insulation and oxide piercing connector employable, for example, for simultaneously interconnecting a plurality of insulated or oxide coated electrical conductors such as magnet wire, flat conductor, or the like, and comprising a plurality of selectively contoured, multi-surfaced, deflectable ridges suitable oriented on at least one interior surface of the connector and proportioned to engage, pierce, and be deflectably locked within the conductors as the connector is crimped thereabout. The ridges may be either straight or curved and formed to cross-sectionally define, alternatively, a generally truncated right triangle, or selective variations thereof, and may be juxtapositionally arranged in either similarly or oppositely facing groups or pairs. Coupling means may be provided for attaching the connector to a further connector or support member.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
214 words
An insulation and oxide piercing electrical connector comprising: a base member having at least one interior surface; and at least a first and second series of generally spaced, elongated upstanding ridges disposed on at least a portion of said interior surface; said first series of said ridges being arranged in similarly facing disposition in a first orientation and said second series of said ridges being arranged in similarly facing disposition in a second orientation opposite to said first orientation; each of said ridges being at least partially defined by a first surface extending outwardly from said interior surface generally normal to the plane thereof and terminating at a first edge, a second surface extending from said first edge of said first surface a first predetermined distance and terminating in a second edge, said second surface forming the top of said ridge, a third surface extending slopingly from said second edge away from said first surface and towards said interior surface a second predetermined distance and terminating at a third edge and a fourth surface extending between and interconnecting said third edge and said interior surface, said ridges being proportioned to engage, pierce and be deflected within the conductive portion of an insulated conductor disposed thereover as said conductor is crimpably engaged about such Conductor.
