Abstract
Abstract An electrical connector for use with an insulated electrical conductor, comprises a ferrule having a transversely extending rib which is located in the ferrule. The rib is generally cylindrical in cross section and extrudes the insulation from the conductor without risk of breaking the conductor as the ferrule and rib are deformed around the conductor.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
142 words
An electrical connector for use with an insulated wire, comprising a ferrule portion having a wire engaging surface and spaced side edges, a rib on said surface and extending transversely with respect to said side edges and the longitudinal axis of said ferrule portion, and a terminal portion adapted to be connected to an electrical conductor, said ferrule portion together with said rib being adapted to be crimped into a generally cylindrical shape around the wire so that said side edges of said ferrule portion are adjacent each other, said rib being generally circular in cross section to penetrate and extrude insulation on the wire and to make good electrical contact with the wire without cutting into the wire as the ferrule portion and rib are crimped around the wire, and said rib being a separate piece secured to said ferrule portion.
Claim 2
Dependent Claim
142 words
An electrical connector for use with an insulated wire, comprising a ferrule portion having a wire engaging surface and spaced side edges, a rib on said surface and extending transversely with respect to said side edges and the longitudinal axis of said ferrule portion, and a terminal portion adapted to be connected to an electrical conductor, said ferrule portion together with said rib being adapted to be crimped into a generally cylindrical shape around the wire so that said side edges of said ferrule portion are adjacent each other, said rib being generally circular in cross section to penetrate and extrude insulation on the wire and to make good electrical contact with the wire without cutting into the wire as the ferrule portion and rib are crimped around the wire, and said rib being a separate piece secured to said ferrule portion.

Claim 12
Independent Claim
76 words
A method for forming a strip of electrical connectors each having a ferrule portion and a rib for use in extruding insulation from an insulated conductor, comprising the steps of: locating a generally elongated wire having a circuit cross section longitudinally along a flat elongated sheet metal strip, bonding said wire to said sheet metal strip; and stamping said sheet metal strip and said wire to form said ferrule portions and said ribs of the connectors.
Claim 13
Independent Claim
76 words
A method for forming a strip of electrical connectors each having a ferrule portion and a rib for use in extruding insulation from an insulated conductor, comprising the steps of: locating a generally elongated wire having a circuit cross section longitudinally along a flat elongated sheet metal strip, bonding said wire to said sheet metal strip; and stamping said sheet metal strip and said wire to form said ferrule portions and said ribs of the connectors.
