Abstract
Abstract This disclosure is directed to a connector and a method for joining electrical conductors thereby. The connector may be crescent shaped with its interior arcuate walls defining two cavities for conductors separated by a rib. The connector is crimped around uninsulated portions of the wires to form an electrical and mechanical connection. The conductors may be secured into the connector seriatim or simultaneously.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
The combination of an electrical connector and a conductor secured therein, said connector being of a malleable, ductile, electrically conductive metal having two arms forming an open recess diverging outwardly at the extremities thereof and integral intermediate connecting portion therebetween, each of said arms having first and second arcuate surfaces, said second arcuate surfaces being positioned near the extremities of said arms to form a closable wire-receiving opening, said second arcuate surfaces being larger than said first arcuate surfaces, and an integral rib between said first and second arcuate surfaces on each of said arms, said rib on each arm being in substantially abutting position with each other and said first arcuate surfaces being in tight mechanical contact with said conductor
Claim 2
Dependent Claim
121 words
The combination of an electrical connector and a conductor secured therein, said connector being of a malleable, ductile, electrically conductive metal having two arms forming an open recess diverging outwardly at the extremities thereof and integral intermediate connecting portion therebetween, each of said arms having first and second arcuate surfaces, said second arcuate surfaces being positioned near the extremities of said arms to form a closable wire-receiving opening, said second arcuate surfaces being larger than said first arcuate surfaces, and an integral rib between said first and second arcuate surfaces on each of said arms, said rib on each arm being in substantially abutting position with each other and said first arcuate surfaces being in tight mechanical contact with said conductor
Claim 3
Dependent Claim
200 words
An integral electrical connector of malleable ductile metal having a pair of arms and an integral connecting portion therebetween defining an open recess between the arms, each of said arms having a first and second inner arcuate surface, each of said second arcuate surfaces being positioned near the extremity of each of said arms and being larger in length than said first arcuate surfaces, and each of said first surfaces being positioned near said connecting portion, each of said arms having an integral rib disposed between said first and second arcuate surfaces, said integral ribs providing a first pair of oppositely outwardly diverging surfaces, and the extremities of the arms providing a second pair of opposed surfaces that are divergent outwardly at a greater angle than the surfaces provided by the ribs, said arms being formed to cause said first arcuate surfaces to surround and grip a first conductor placed therein and to cause said integral ribs to be in abutting relationship thereto upon crimping together the portions of said arms containing the first arcuate surfaces while maintaining open said recess between the second arcuate surfaces to permit later insertion and crimping the second arcuate surfaces about a second conductor.
Claim 4
Dependent Claim
200 words
An integral electrical connector of malleable ductile metal having a pair of arms and an integral connecting portion therebetween defining an open recess between the arms, each of said arms having a first and second inner arcuate surface, each of said second arcuate surfaces being positioned near the extremity of each of said arms and being larger in length than said first arcuate surfaces, and each of said first surfaces being positioned near said connecting portion, each of said arms having an integral rib disposed between said first and second arcuate surfaces, said integral ribs providing a first pair of oppositely outwardly diverging surfaces, and the extremities of the arms providing a second pair of opposed surfaces that are divergent outwardly at a greater angle than the surfaces provided by the ribs, said arms being formed to cause said first arcuate surfaces to surround and grip a first conductor placed therein and to cause said integral ribs to be in abutting relationship thereto upon crimping together the portions of said arms containing the first arcuate surfaces while maintaining open said recess between the second arcuate surfaces to permit later insertion and crimping the second arcuate surfaces about a second conductor.
Claim 5
Dependent Claim
35 words
An integral electrical connector as in claim 2 wherein the connector is crescent shape in configuration. 4 An integral electrical connector as in claim 2 wherein the connector is made of a sintered powdered metal.
