Abstract
Abstract A multiplicity of integrated circuit connector contact sockets mounted to a plurality of carrier strips are moved between pairs of orientation rollers with tails of the contacts protruding upwardly whereby an upper socket portion of one contact is aligned with an upper socket portion of a contact on a carrier strip in an adjacent row. A plurality of integrated circuit connector insulators having socket receiving apertures formed therein are held together in an array and placed over the contact tails with one tail being received within each aperture of an insulator. The carrier strips are simultaneously advanced beneath a work station wherein a tool presses the insulators downwardly to tightly fit the contact socket portions into the receiving apertures in the insulators. A shearing tool then severs the insulators in the array from one another except for the continued affixation of the contact sockets to the parallel carrier strips. The carrier strips are then moved through a stripping station comprising a block having parallel channels for receiving the carrier strips and a flat inclined upper surface wherein the carrier strips are restrained from vertical movement while the inclined ramp strips the insulator mounted contacts from the carrier strips to form completed individual connectors.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
221 words
Apparatus for assembling socket contacts mounted to a plurality of carrier strips with integrated circuit connector insulators provided in predefined arrays, each of said contacts comprising an enlarged upper socket portion received within apertures in the insulator for receiving integrated circuit leads therein and a lower tail portion for depending from said insulator for electrical connection, said apparatus comprising: a generally horizontal surface having a plurality of generally parallel channels formed longitudinally thereacross for receiving contact carrier strips having contact sockets affixed thereto and contact tails extending transversely thereof; means for advancing said contact carrier strips upon said horizontal surface in synchronized, intermittent movement of predefined longitudinal distances; means for aligning the tails of the contacts extending from the carrier strips upon said surface into preselected alignment for being received into apertures formed in linear rows in the insulators and positioned in linear alignment within the insulator array; means for press-fitting the contact socket portions into the apertures of the insulator of the array; means for separating individual ones of said insulators of the array one from the other upon said horizontal surface to provide individual integrated circuit connector assemblies; and means for separating said connector assemblies from said carrier strip including means for advancing said assembled contacts and insulators transversely relative to the carrier strips for removing the contacts therefrom.
Claim 2
Dependent Claim
221 words
Apparatus for assembling socket contacts mounted to a plurality of carrier strips with integrated circuit connector insulators provided in predefined arrays, each of said contacts comprising an enlarged upper socket portion received within apertures in the insulator for receiving integrated circuit leads therein and a lower tail portion for depending from said insulator for electrical connection, said apparatus comprising: a generally horizontal surface having a plurality of generally parallel channels formed longitudinally thereacross for receiving contact carrier strips having contact sockets affixed thereto and contact tails extending transversely thereof; means for advancing said contact carrier strips upon said horizontal surface in synchronized, intermittent movement of predefined longitudinal distances; means for aligning the tails of the contacts extending from the carrier strips upon said surface into preselected alignment for being received into apertures formed in linear rows in the insulators and positioned in linear alignment within the insulator array; means for press-fitting the contact socket portions into the apertures of the insulator of the array; means for separating individual ones of said insulators of the array one from the other upon said horizontal surface to provide individual integrated circuit connector assemblies; and means for separating said connector assemblies from said carrier strip including means for advancing said assembled contacts and insulators transversely relative to the carrier strips for removing the contacts therefrom.
Claim 3
Dependent Claim
76 words
The apparatus as set forth in claim 1 wherein said means for advancing said assembled contacts and insulators includes a slotted incline plane positioned upon said surface, said slots receiving said carrier strips therein and said incline plane receiving said insulators thereupon, and means for restraining said carrier strips from vertical movement during the advance of said strips within said slots to impart movement of said insulators along said plane and transversely away from said strips.
Claim 4
Dependent Claim
27 words
The apparatus as set forth in claim 1 wherein said means for separating said insulator comprises a shearing tool disposed above said insulator array upon said surface.
Claim 5
Dependent Claim
56 words
The apparatus as set forth in claim 1 wherein said means for advancing said carrier strips upon said surface includes means for engaging a plurality of said carrier strips in selective alignment one with the other and simultaneously moving said strips forward the distance of the center-to-center spacing of the insulator arrays along the carrier strip.
Claim 6
Dependent Claim
35 words
The apparatus as set forth in claim 4 wherein said means for moving said strips forward includes means for securing said strips against forward motion when said alignment means and said press-fitting means are actuated.
Claim 7
Dependent Claim
62 words
The apparatus as set forth in claim 5 wherein said apparatus further includes means for simultaneously actuating said press-fitting means, said alignment means and said means for separating said insulators, and wherein said press-fitting means, said alignment means and said separating means are disposed upon said surface at locations relative to said carrier strips which are longitudinally disposed one from the other.
