Abstract
Abstract A connector for connecting leads from an integrated circuit package to a printed circuit board or the like wherein the connection between the circuit board and the semiconductor chip leads are as short as possible. This is accomplished by providing a frame which abuts the chip carrier and leads extending therefrom whereby the leads are formed over a frame and travel in a direct path to pads on the printed circuit board. Spring members are held in the frame by a yoke, there being one spring element for each lead which forces the chip carrier leads against the printed circuit pad directly thereby obtaining the shortest possible path.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A separable electrical connector, comprising: a semiconductor chip carrier having leads extending therefrom; a frame adjacent to said carrier, said leads extending through said frame; circuit board means adjacent to said frame and having electrically conductive pads thereon in alignment with said leads, each of said leads being disposed on one of said pads; a spring means disposed on each side of said frame, said spring means having a plurality of electrically insulating tips for engaging each of said leads so as to cause said leads to be compressed against the pads thereby providing electrical communication between said leads and said pads, said spring means further having a finger extending upward from said spring means for engagable engaging a yoke means; yoke means pivotally attached to one of said fingers for engaging remaining said fingers so as to cause said spring members and thereby said tips to exert a contact-mating force between said leads and said pads.
Claim 2
Dependent Claim
157 words
A separable electrical connector, comprising: a semiconductor chip carrier having leads extending therefrom; a frame adjacent to said carrier, said leads extending through said frame; circuit board means adjacent to said frame and having electrically conductive pads thereon in alignment with said leads, each of said leads being disposed on one of said pads; a spring means disposed on each side of said frame, said spring means having a plurality of electrically insulating tips for engaging each of said leads so as to cause said leads to be compressed against the pads thereby providing electrical communication between said leads and said pads, said spring means further having a finger extending upward from said spring means for engagable engaging a yoke means; yoke means pivotally attached to one of said fingers for engaging remaining said fingers so as to cause said spring members and thereby said tips to exert a contact-mating force between said leads and said pads.
Claim 3
Dependent Claim
36 words
A device according to claim 1 wherein said spring means has a tab disposed at each end thereof for engaging with a recess contained in said frame, thereby pivotally attaching said spring means to said frame.
Claim 4
Dependent Claim
29 words
A device according to claim 1 wherein said spring means is comprised of a substantially U-shaped member said tips extending from one end thereof for engaging with said leads.
Claim 5
Dependent Claim
27 words
A device according to claim 1 wherein said spring means is comprised of an electrically-conductive spring member with an electrically-insulating material disposed on each of said tips.
