Abstract
Abstract An active electrical pin contact comprises a hollow pin contact section having a longitudinal seam extending from one end to the other and including opposed recessed areas defining a longitudinal slot. A spring member is disposed in the hollow pin contact section and it includes a linear section, a bowed section, and a front arcuate section. The linear section and the front arcuate section extend along an inside surface of the hollow pin contact section and the bowed section is disposed in the longitudinal slot including a contact-engaging section extending outwardly beyond an outside surface of the hollow pin contact section.

Claim 1
Independent Claim
217 words
An active electrical pin contact including a hollow pin contact section and a conductor-connecting section for electrical connection with an electrical conductor, a spring member secured in said pin contact section, characterized in that said hollow pin contact section being partly formed with a rounded nose portion and with edges to be abutted including opposed recessed areas therealong to form a longitudinal slot being spaced a predetermined distance from each other forming a longitudinal gap therealong; said spring member having a linear section, a bowed section and a short front section which has a curved configuration reverse to that of said bowed section; said spring member being inserted into said hollow pin contact section through said longitudinal gap with said linear section extending along an inside surface of said hollow pin contact section, said bowed section having a contact-engaging section extending above an outside surface of said hollow pin contact section within the opposed recessed areas and said curved front section extending along said inside surface spaced from an inside curved surface of the partly-formed nose portion; said hollow pin contact section being formed into its final configuration with said edges in abutment thereby permitting at least said curved front section to move along said inside surface when an inward force is exerted onto said contact-engaging section.

An active electrical pin contact including a hollow pin contact section and a conductor-connecting section for electrical connection with an electrical conductor, a spring member secured in said pin contact section, characterized in that said hollow pin contact section being partly formed with a rounded nose portion and with edges to be abutted including opposed recessed areas therealong to form a longitudinal slot being spaced a predetermined distance from each other forming a longitudinal gap therealong; said spring member having a linear section, a bowed section and a short front section which has a curved configuration reverse to that of said bowed section; said spring member being inserted into said hollow pin contact section through said longitudinal gap with said linear section extending along an inside surface of said hollow pin contact section, said bowed section having a contact-engaging section extending above an outside surface of said hollow pin contact section within the opposed recessed areas and said curved front section extending along said inside surface spaced from an inside curved surface of the partly-formed nose portion; said hollow pin contact section being formed into its final configuration with said edges in abutment thereby permitting at least said curved front section to move along said inside surface when an inward force is exerted onto said contact-engaging section.
Claim 3
Dependent Claim
33 words
An active electrical pin contact as set forth in claim 1 characterized in that a dimple is formed rearwardly of said longitudinal slot securing said linear section in position against said inside surface.
Claim 4
Dependent Claim
39 words
An active electrical pin contact as set forth in claim 1 characterized in that said hollow pin contact section includes opposed arcuate recesses in said edges forming a hole to provide a relief area when said dimple is formed.
Claim 5
Dependent Claim
125 words
An active electrical pin contact comprising: a hollow pin contact section and a conductor-connection section, said pin contact section having a longitudinal seam extending from one end to the other and including opposed recessed areas defining a longitudinal slot; a spring member disposed in said hollow pin contact section including a linear section, a bowed section and a front arcuate section, said linear section and said front arcuate section extending along an inside surface of said hollow pin contact section and said bowed section disposed in said longitudinal slot including a contact-engaging section extending outwardly beyond an outside surface of said hollow pin contact section, said front arcuate section being movable along said inside surface when an inward force is exerted onto said contact-engaging section.
Claim 6
Dependent Claim
125 words
An active electrical pin contact comprising: a hollow pin contact section and a conductor-connection section, said pin contact section having a longitudinal seam extending from one end to the other and including opposed recessed areas defining a longitudinal slot; a spring member disposed in said hollow pin contact section including a linear section, a bowed section and a front arcuate section, said linear section and said front arcuate section extending along an inside surface of said hollow pin contact section and said bowed section disposed in said longitudinal slot including a contact-engaging section extending outwardly beyond an outside surface of said hollow pin contact section, said front arcuate section being movable along said inside surface when an inward force is exerted onto said contact-engaging section.
Claim 7
Dependent Claim
22 words
An active electrical pin contact as set forth in claim 4 wherein said hollow pin contact section has a rounded nose section.
Claim 8
Dependent Claim
26 words
An active electrical pin contact as set forth in claim 4 and further comprising: a dimple anchoring said linear section in position along said inside surface.
Claim 9
Dependent Claim
33 words
An active electrical pin contact as set forth in claim 6 and further comprising: opposed arcuate areas in said longitudinal seam forming a hole defining a relief area when said dimple is formed.
