Abstract
Abstract An electrical socket contact for receiving a pin contact, the socket comprising a forward end comprised of at least two elongated cantilever spring tines for receiving the pin, each spring tine extending from a concave cross-section adjacent to the body from which it extends and transitioning into a convex cross-section adjacent to its free end, the free ends being tulip-shaped to form an entry for guiding the pin contact into engagement by the convex portions. Apparatus for manufacturing the contact includes a center die having shaped grooves, arcuate segments which close together about the die and have shaped ribs which are received in a respective groove, and an entrance die having a hemispherical protrusion which is inserted into an opening defined by the closed segments.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
An electrical socket contact for receiving a pin contact, said socket comprising an elongated cylindrical body formed from electrically conductive material and having a forward end comprised of at least two elongated spring tines, substantially identical in configuration, for receiving the pin, the socket characterized in that each spring tine extends as a cantilever from the body to a free end and has a convex cross-section adjacent its free end for engaging the pin contact, the tines collectively and uniformly transition from the convex cross-sections into concave cross-sections adjacent to the body from which the tines extend, and the free ends cooperating to form a tulip-shaped entry for guiding the pin contract.
Claim 2
Dependent Claim
112 words
An electrical socket contact for receiving a pin contact, said socket comprising an elongated cylindrical body formed from electrically conductive material and having a forward end comprised of at least two elongated spring tines, substantially identical in configuration, for receiving the pin, the socket characterized in that each spring tine extends as a cantilever from the body to a free end and has a convex cross-section adjacent its free end for engaging the pin contact, the tines collectively and uniformly transition from the convex cross-sections into concave cross-sections adjacent to the body from which the tines extend, and the free ends cooperating to form a tulip-shaped entry for guiding the pin contract.
Claim 3
Dependent Claim
35 words
The electrical socket contact as recited in claim 1 wherein each spring tine has a pair of longitudinally extending edges each said edge being spaced away from and in disengaged relation with the pin contact.
Claim 4
Dependent Claim
47 words
The electrical socket contact as recited in claim 1 including guide means for guiding the pin contact to the spring tines, said guide means comprising an elongated cylindrical hood encircling the spring tines and having an inwardly converging throat for guiding the pin into the socket contact.
Claim 5
Dependent Claim
34 words
The electrical socket contact as recited in claim 2 wherein the covex portion of each spring tine is longitudinally extending whereby to assure a linear engagement with the outer periphery of the pin contact.
Claim 6
Dependent Claim
39 words
The electrical socket contact as recited in claim 2 wherein the edges of adjacent spring tines define a longitudinally extending slot having an angular separation adjacent to the roots which is different than that adjacent to the free ends.
