Connector and closure clip for a rectangular circuit support

Claim 2

A connector for a chip carrier comprising: a rectangular base having four corners with a clip housing disposed at each of said four corners, said base being adapted to contact a chip carrier having first and second faces, with electrical contact zones disposed on at least one of said faces, said base having flexible contacts which are adapted to receive corresponding contact zones on the first face of said chip carrier; and a clip adapted to bear on the second face of said chip carrier so as to maintain electric continuity between said contact zones and said flexible contacts, said clip including a rectangular frame having four corners, said frame being substantially in one plane when said clip bears on said chip carrier, said frame having two cross arms forming opposite sides of said rectangular frame, said frame having at least two bearing arms forming opposite sides of said rectangular frame, being connected together by said cross arms, each of said bearing arms including a bearing zone substantially in the middle thereof and two symmetrical half arms connecting to said bearing zone, each of said half arms generally widening in the vicinity of said bearing zone, so as to impart substantially equal resistance to bending along each half arm, each pair of half arms forming an angle out of said plane of said frame when said clip is not bearing on said chip carrier, said bearing zone being disposed at the vertex of said angle and oriented to compressibly contact said chip carrier when said clip is bearing on said chip carrier, and hooks for removably fixing said clip to said rectangular base, one of said hooks being disposed at each of said four corners of said rectangular frame to correspondingly engage each of said clip housings of said base.

Claim 3

A connector as claimed in claim 1, wherein said clip is removably fixed to said rectangular base by flexible hooks which correspondingly engage said clip housings by temporarily expanding and then releasing so as to snap-fit onto said clip housings.

Claim 4

A connector as claimed in claim 1, wherein each of said bearing arms has an internal edge and each of said bearing zones has a projecting member situated on said internal edge causing increased bearing force of said bearing arm to be exerted on said chip carrier.

Claim 5

A connector as claimed in claim 1, wherein said cross arms of said frame have a bowed shape, curving in the same general direction as said angle of said bearing arms, each of said cross arms having an internal edge and each of said cross arms being offset toward said internal edge such that said internal edge at the apex of said bowed cross arm presents a bearing point of said cross arm on said chip carrier.

Claim 6

A connector as claimed in claim 1 wherein each of said bearing zones of each of said bearing arms has an external edge having a stud-like member for fixing a cooling device.

Claim 7

A connector for a chip carrier comprising: a rectangular base having four corners with a clip housing disposed at each of said corners, said base being adapted to contact a chip carrier having first and second faces, with electrical contact zones disposed on at least one of said faces, said base having flexible contacts which are adapted to receive corresponding contact zones on the first face of said chip carrier; and a clip adapted to bear on the second face of said chip carrier so as to maintain electric continuity between said contact zones and said flexible contacts, said clip including a rectangular frame having four corners, said frame having two cross arms being substantially in one plane when said clip bears on said chip carrier, forming opposite sides of said rectangular frame, and said frame having at least two bearing arms forming opposite sides of said rectangular frame, being connected together by said cross arms, each of said bearing arms being including a bearing zone substantially in the middle thereof and two symmetrical half arms connecting to said bearing zone, each of said bearing arms having an internal edge and each of said bearing zones having a projecting member situated on said internal edge causing increasing bearing force of said bearing arm to be exerted on said chip carrier, each of said half arms generally widening in the vicinity of said bearing zone so as to impart substantially equal resistance to bending along each half arm, each pair of half arms forming an angle out of said plane of said frame when said clip is not bearing on said chip carrier, said bearing zone being disposed at the vertex of said angle and oriented to compressibly contact said chip carrier when said clip is bearing on said chip carrier, hooks for removably fixing said clip to said rectangular base, one of said hooks being disposed at each of said four corners of said rectangular frame to correspondingly engage each of said clip housings of said base.

Claim 8

A connector for a chip carrier comprising: a rectangular base having four corners with a clip housing disposed at each of said corners, said base being adapted to contact a chip carrier having first and second faces, with electrical contact zones disposed on at least one of said faces, said base having flexible contacts which are adapted to receive corresponding contact zones on the first face of said chip carrier; and a clip adapted to bear on the second face of said chip carrier so as to maintain electric continuity between said contact zones and said flexible contacts, said clip including a rectangular frame having four corners, said frame having two cross arms being substantially in one plane when said clip bears on said chip carrier, forming opposite sides of said rectangular frame, and said frame having at least two bearing arms forming opposite sides of said rectangular frame, being connected together by said cross arms, each of said bearing arms being including a bearing zone substantially in the middle thereof and two symmetrical half arms connecting to said bearing zone, each of said bearing arms having an internal edge and each of said bearing zones having a projecting member situated on said internal edge causing increasing bearing force of said bearing arm to be exerted on said chip carrier, each of said half arms generally widening in the vicinity of said bearing zone so as to impart substantially equal resistance to bending along each half arm, each pair of half arms forming an angle out of said plane of said frame when said clip is not bearing on said chip carrier, said bearing zone being disposed at the vertex of said angle and oriented to compressibly contact said chip carrier when said clip is bearing on said chip carrier, hooks for removably fixing said clip to said rectangular base, one of said hooks being disposed at each of said four corners of said rectangular frame to correspondingly engage each of said clip housings of said base.

Claim 9

A connector as claimed in claim 6, wherein said clip is removably fixed to said rectangular based by flexible hooks which correspondingly engage said clip housings by temporarily expanding and then releasing so as to snap-fit onto said clip housings.

Claim 10

A connector as claimed in claim 6, wherein said cross arms of said frame have a bowed shape, curving in the same general direction as said angle of said bearing arms, each of said cross arms having an internal edge and each of said cross arms being offset toward said internal edge such that said internal edge at the apex of said bowed cross arm presents a bearing point of said cross arm on said chip carrier.

Claim 11

A connector as claimed in claim 6 wherein each of said bearing zones of each of said bearing arms has an external edge having a stud-like member for fixing a cooling device.
