Abstract
Abstract Stamped and formed connecting device for splicing a small diameter lead wire to a larger diameter resistor core comprises a U-shaped connecting member having a web and sidewalls. The web has a semicylindrical central depression for the lead wire and has arcuate portions on each side of the depression which conform to the resistor core. The sidewalls are reversely folded at their outer ends to provide inner and outer layers. The ends of the inner layers are located adjacent to the depression. In use, the lead wire is located in the depression, the resistor core is positioned between the sidewalls, and the sidewalls are crimped onto the resistor. The ends of the inner layers move relatively towards, and against, the lead wire during crimping and establish contact with the lead wire. Contact with the resistor core is established by the inner surfaces of the inner layers of the sidewalls.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A stamped and formed connecting device for connecting a relatively small diameter lead wire to a relatively large diameter core of a resistor, said connecting device comprising: a generally U-shaped member having a web and sidewalls extending from said web, said web having a centrally located depression extending axially therein, said sidewalls having outer ends, each of said sidewalls being reversely folded at said outer ends whereby each of said sidewalls comprises an inner layer and an outer layer, said inner layer of each sidewall extending to said web and having an end which is located adjacent to said depression whereby, upon locating said lead wire in said depression, positioning said resistor core on said lead wire and between said sidewalls, and crimping said connecting device onto said resistor core by bending said sidewalls towards each other and into constrictive embracing relationship with said resistor core, said ends of said inner layer move against, and establish electrical contact with, said lead wire, and internal surface portions of said inner layer establish electrical contact with said resistor core.
Claim 2
Dependent Claim
177 words
A stamped and formed connecting device for connecting a relatively small diameter lead wire to a relatively large diameter core of a resistor, said connecting device comprising: a generally U-shaped member having a web and sidewalls extending from said web, said web having a centrally located depression extending axially therein, said sidewalls having outer ends, each of said sidewalls being reversely folded at said outer ends whereby each of said sidewalls comprises an inner layer and an outer layer, said inner layer of each sidewall extending to said web and having an end which is located adjacent to said depression whereby, upon locating said lead wire in said depression, positioning said resistor core on said lead wire and between said sidewalls, and crimping said connecting device onto said resistor core by bending said sidewalls towards each other and into constrictive embracing relationship with said resistor core, said ends of said inner layer move against, and establish electrical contact with, said lead wire, and internal surface portions of said inner layer establish electrical contact with said resistor core.
Claim 3
Dependent Claim
29 words
A stamped and formed connecting device as set forth in claim 1, said device being substantially symmetrical about a vertical axis extending through said depression and between said sidewalls.
Claim 4
Dependent Claim
29 words
A stamped and formed connecting device as set forth in claim 1, said depression being semi-cylindrical and having a radius which conforms to the radius of said lead wire.
Claim 5
Dependent Claim
26 words
A stamped and formed connecting device as set forth in claim 1, said ends of said inner layers being tapered to facilitate contact with said wire.
Claim 6
Dependent Claim
46 words
A stamped and formed connecting device as set forth in claim 1, said depression being semi-cylindrical and having a radius which conforms to the radius of said lead wire, said web being semi-cylindrical and having a radius which conforms to the radius of said resistor core.
