Abstract
Abstract A socket contact of beryllium copper crimped on a conductor wire and having tines surrounding a socket for receiving the pin of a pin contact, and heat treated after being so crimped, hardening the socket contact, providing springiness and wear resistance to the tines, and improving conductivity of the socket contact.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A method of making an electrically conductive component including the steps providing a conductor wire, providing a one-piece connector member of soft deformable material capable of being hardened by heat treating and having a crimp pocket end for receiving the conductor wire, and a socket end for receiving a mating contact, crimping the soft pocket end of the connector member on the conductor wire to deform the pocket end on the wire to form a unitary and effectively integral member, and heat treating the connector member under conditions for hardening the material of the connector to increase the hardness of the crimped pocket end and the socket end.
Claim 2
Independent Claim
108 words
A method of making an electrically conductive component including the steps providing a conductor wire, providing a one-piece connector member of soft deformable material capable of being hardened by heat treating and having a crimp pocket end for receiving the conductor wire, and a socket end for receiving a mating contact, crimping the soft pocket end of the connector member on the conductor wire to deform the pocket end on the wire to form a unitary and effectively integral member, and heat treating the connector member under conditions for hardening the material of the connector to increase the hardness of the crimped pocket end and the socket end.
Claim 3
Dependent Claim
36 words
A method according to claim 1 wherein said socket end has longitudinally extending and circumferentially spaced tines, and whereby the hardness is imparted also to the tines, and increased tensile strength is imparted to the tines.
Claim 4
Dependent Claim
18 words
A method according to claim 2 which includes the step of providing a connector member of beryllium copper.
Claim 5
Dependent Claim
28 words
A method according to claim 3 wherein the heat treatment includes heating the connector member at in the neighborhood of 600*F. for in the neighborhood of 2 hours.
Claim 6
Dependent Claim
35 words
A method according to claim 1 and including the step of providing a connector member of beryllium copper and a conductive wire of high-pure copper, and placing the item thus produced in the heat treatmEnt.
Claim 7
Dependent Claim
27 words
A method according to claim 2 and including the steps of forming in the tines to produce a reduced internal socket, and thereafter performing the heating step.
