Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
In a connector for an integrated circuit having a flexible printed circuit provided with at least one contact for said integrated circuit and with corresponding edge contact strips for electrical connection of said integrated circuit to external pads, and resilient means for maintaining contact pressure between the contacts and the integrated circuit, the improvement wherein: the connector comprises (a) an upper plate, (b) an electrically insulating connecting plate provided with at least one receiving hole, each hole receiving an integrated circuit, (c) an electrically insulating lower plate, provided at its upper side with at least one receiving recess for said resilient means situated in line with a receiving hole in the connecting plate, and provided at two opposite sides with external pads at the upper side of the lower plate, said flexible circuit being flat and positioned between the connecting plate and the lower plate, said contacts for said integrated circuit being situated in line with a receiving hole in the connecting plate, said edge contact strips being situated in line with said pads, there being an insulation strip covering the flexible circuit at its under side within the edge contact strips, and said resilient means being provided in each of the receiving holes in the lower plate, each resilient means having a number of separate resilient elements each of which is in line with a corresponding contact.
Claim 2
Dependent Claim
228 words
In a connector for an integrated circuit having a flexible printed circuit provided with at least one contact for said integrated circuit and with corresponding edge contact strips for electrical connection of said integrated circuit to external pads, and resilient means for maintaining contact pressure between the contacts and the integrated circuit, the improvement wherein: the connector comprises (a) an upper plate, (b) an electrically insulating connecting plate provided with at least one receiving hole, each hole receiving an integrated circuit, (c) an electrically insulating lower plate, provided at its upper side with at least one receiving recess for said resilient means situated in line with a receiving hole in the connecting plate, and provided at two opposite sides with external pads at the upper side of the lower plate, said flexible circuit being flat and positioned between the connecting plate and the lower plate, said contacts for said integrated circuit being situated in line with a receiving hole in the connecting plate, said edge contact strips being situated in line with said pads, there being an insulation strip covering the flexible circuit at its under side within the edge contact strips, and said resilient means being provided in each of the receiving holes in the lower plate, each resilient means having a number of separate resilient elements each of which is in line with a corresponding contact.
Claim 3
Dependent Claim
54 words
A connector according to claim 1 wherein the upper plate, the connecting plate and the lower plate each have at two opposite ends a recess, in line at each end with each other for the three plates, and a clamping bracket positioned over said recesses for keeping the three plates locked on each other.
Claim 4
Dependent Claim
16 words
A connector according to claim 1 characterized in that the upper plate is of heat-conducting metal.
Claim 5
Dependent Claim
20 words
A connector according to claim 1 characterized in that the upper plate has heat dispensing ribs at its upper side.
