Abstract
Abstract An electronic socket carrier system in which a plurality of lead sockets are mounted on a thin flexible carrier strip which can be removed from the sockets after their mounting on a circuit board. The lead sockets each include retention elements on the socket body to retain the socket on the carrier strip and which can also be employed for locking the socket into a mounting hole of a circuit board. The sockets are preferably cold formed and have a plurality of barbs each with a ramp surface to facilitate installation of the sockets into cooperative holes in the carrier strip, and an edge portion for retaining the socket once installed on the carrier strip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
An electronic socket for mounting on a flexible carrier strip, comprising: a metal sleeve having an internal bore and contacts therein for engaging a lead of an electronic component, the bore having a lead entry at an upper open end; a first plurality of circumferentially spaced barbs disposed at a first axial position on the sleeve; and a second plurality of circumferentially spaced barbs disposed at a second axial position in the sleeve, wherein; the first and second pluralities of barbs are operative to retain the socket within the plated hole of a circuit board.
Claim 2
Dependent Claim
95 words
An electronic socket for mounting on a flexible carrier strip, comprising: a metal sleeve having an internal bore and contacts therein for engaging a lead of an electronic component, the bore having a lead entry at an upper open end; a first plurality of circumferentially spaced barbs disposed at a first axial position on the sleeve; and a second plurality of circumferentially spaced barbs disposed at a second axial position in the sleeve, wherein; the first and second pluralities of barbs are operative to retain the socket within the plated hole of a circuit board.
Claim 3
Independent Claim
106 words
A method of fabricating a lead socket comprising the steps of: cold forming a sleeve having a head portion, a first contiguous portion, a second contiguous portion of smaller diameter than the first contiguous portion, and a tapered transition section between the first contiguous portion and second contiguous portion; cold forming circumferentially spaced portions of the first contiguous portion to provide circumferentially spaced barbs, wherein said step includes upsetting the first contiguous portion at spaced circumferential positions by plowing the material in an axial direction from the transition section toward the head portion to form the circumferentially spaced barbs which outwardly taper toward the head end.
Claim 4
Independent Claim
106 words
A method of fabricating a lead socket comprising the steps of: cold forming a sleeve having a head portion, a first contiguous portion, a second contiguous portion of smaller diameter than the first contiguous portion, and a tapered transition section between the first contiguous portion and second contiguous portion; cold forming circumferentially spaced portions of the first contiguous portion to provide circumferentially spaced barbs, wherein said step includes upsetting the first contiguous portion at spaced circumferential positions by plowing the material in an axial direction from the transition section toward the head portion to form the circumferentially spaced barbs which outwardly taper toward the head end.
Claim 5
Independent Claim
105 words
A method of fabricating a lead socket comprising the steps of: machining a sleeve having a head portion, a first contiguous portion, a second contiguous portion of smaller diameter than the first contiguous portion, and a tapered transition section between the first contiguous portion and second contiguous portion; cold forming circumferentially spaced portion of the first contiguous portion to provide circumferentially spaced barbs, wherein said step includes upsetting the first contiguous portion at spaced circumferential positions by plowing the material in an axial direction from the transition section toward the head portion to form the circumferentially spaced barbs which outwardly taper toward the head end.
