Abstract
Abstract An electrical connector for electrically connecting a plurality of insulated wires together. The connector includes two unitary ferrule forming portions, one mounted inside the other with their sidewalls substantially parallel to and spaced from one another, and connected to one another at one side. Insulation piercing serrations run transversely across the inside of the larger ferrule forming portion and the outside of the smaller ferrule forming portion such that the insulation on a plurality of wires mounted there-between may be pierced when the connector is crimped. In addition, the inside of the smaller ferrule forming portion has a plurality of slots running transversely thereacross which act to pierce the insulation of any wires crimped inside.

Claim 1
Independent Claim
186 words
A crimpable electrical connector for electrically connecting a plurality of electrical conductors together, which comprises: a first U-shaped ferrule forming portion, said first U-shaped ferrule forming portion including first and second spaced apart sidewalls, and inside and outside surfaces on said first ferrule forming portion; a second U-shaped ferrule forming portion, said second U-shaped ferrule forming portion including first and second spaced apart sidewalls, inside and outside surfaces on said second U-shaped ferrule forming portion, said second U-shaped ferrule forming portion being located inside said first ferrule forming portion with said first sidewalls on said first and second ferrule forming portions extending substantially parallel to and spaced from one another and said second sidewalls on said first and second ferrule forming portions being unitary with, and extending substantially parallel to and spaced from one another; and insulation piercing means on the inside surface of said first Ushaped ferrule forming portion and on the inside and outside surfaces of said second ferrule forming portion whereby said insulation piercing means on said surfaces pierces through the insulation on a wire adjacent thereto when said connector is crimped closed.

A crimpable electrical connector for electrically connecting a plurality of electrical conductors together, which comprises: a first U-shaped ferrule forming portion, said first U-shaped ferrule forming portion including first and second spaced apart sidewalls, and inside and outside surfaces on said first ferrule forming portion; a second U-shaped ferrule forming portion, said second U-shaped ferrule forming portion including first and second spaced apart sidewalls, inside and outside surfaces on said second U-shaped ferrule forming portion, said second U-shaped ferrule forming portion being located inside said first ferrule forming portion with said first sidewalls on said first and second ferrule forming portions extending substantially parallel to and spaced from one another and said second sidewalls on said first and second ferrule forming portions being unitary with, and extending substantially parallel to and spaced from one another; and insulation piercing means on the inside surface of said first Ushaped ferrule forming portion and on the inside and outside surfaces of said second ferrule forming portion whereby said insulation piercing means on said surfaces pierces through the insulation on a wire adjacent thereto when said connector is crimped closed.
Claim 3
Dependent Claim
132 words
A crimpable electrical connector for electrically connecting a plurality of electrical conductors, which comprises: a first ferrule forming portion having inside and outsidE surfaces; a second ferrule forming portion unitary with said first ferrule forming portion, said second ferrule forming portion having inside and outside surfaces and being located inside said first ferrule forming portion with said outside surface of said second ferrule forming portion facing said inside surface on said first ferrule forming portion and spaced there-from; insulation piercing serrations on the inside surface of said first ferrule forming portion and on the outside surface of said second ferrule forming portion; and insulation piercing perforations in said second ferrule forming portion, said perforations having burrs at the intersection of said perforations with said inside surface of said second ferrule forming portion.
