Abstract
Abstract A connector is described for removable electrical connection of an array package having a plurality of pins. A first board having a plurality of openings formed therethrough and a second parallel board having a plurality of complementary contact elements extending into the openings are interconnected by a heat-recoverable metal motion transmitting means preferably in the form of a grid positioned between the boards. One end of the grid is connected to the first board and the other end of the grid is connected to the second board to move the boards relative to each other causing engagement between the contact elements and the pins of an array package that may be inserted into the openings.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
93 words
A connector comprising: a first board having a plurality of openings formed therethrough; a second board having a plurality of contact elements associated therewith, said second board being mounted parallel to said first board and said contact elements being complementary to said openings and extending into said openings; and a heat-recoverable metal motion transmitting means interconnecting said first and second boards to move said boards relative to each other, movement of said boards causing engagement between said contact elements and the pins of a multipin module that may be inserted into said openings.
Claim 2
Dependent Claim
93 words
A connector comprising: a first board having a plurality of openings formed therethrough; a second board having a plurality of contact elements associated therewith, said second board being mounted parallel to said first board and said contact elements being complementary to said openings and extending into said openings; and a heat-recoverable metal motion transmitting means interconnecting said first and second boards to move said boards relative to each other, movement of said boards causing engagement between said contact elements and the pins of a multipin module that may be inserted into said openings.
Claim 3
Dependent Claim
21 words
A connector, as in claim 1, wherein said heat-recoverable metal motion transmitting means is disposed between said first and second boards.
Claim 4
Dependent Claim
72 words
A connector as in claim 2 wherein said heat-recoverable metal motion transmitting means comprises a grid having first and second ends and having webs of material extending between said first and second ends defining at least one slot between said webs, said contact elements being positioned within said slot, the first end of said grid connected to said first board to the second end of said grid connected to said second board.
Claim 5
Dependent Claim
39 words
A connector as in claim 3, wherein said slot is wider than the width of said openings and the contact elements so as to be insulated from the contact elements and pins that may be inserted into said openings.
Claim 6
Dependent Claim
80 words
A connector as in claims 1 or 4 wherein said heat-recoverable metal transmitting means is made from a heat-recoverable metal having a martensitic state and austenitic state, said means being expanded dimensionally while in its martensitic state to allow insertion of pins of a multipin module, a change from its martensitic state to its austenitic state recovering said means to its non-expanded dimension thus moving the boards relative to each other causing engagement with the pins of a multipin module.
Claim 7
Dependent Claim
51 words
A device as in claim 5 wherein said first and second boards are provided with separate biasing means to bias said first board relative to said second board to disengage pins that may be inserted into said openings when said heat-recoverable metal goes from its austenitic state to its martensitic state.
Claim 8
Dependent Claim
43 words
A connector as in claim 5 wherein the contact elements bias said first board relative to said second board to disengage pins that may be inserted into said openings when said heat recoverable metal goes from its austenitic state to its martensitic state.
Claim 9
Dependent Claim
29 words
A connector as in claims 3 or 4 wherein said webs are coated with thermally insulating material to thermally insulate said webs and to decrease friction between the boards.
Claim 10
Dependent Claim
56 words
A connector as in claims 1 or 4 wherein said second board contains a plurality of pin openings complementary to the openings in said first board to allow pins of a multipin module that may be inserted into said openings of said first board to be further inserted into said pin openings of the second board.
Claim 11
Dependent Claim
37 words
A connector as in claim 5 wherein said heat-recoverable metal transmitting means is made from a trained heat-recoverable metal which will reversably transform from its recovered austenitic state to its expanded martensitic state upon change in temperature.
Claim 12
Dependent Claim
19 words
A connector as in claim 1 wherein the heat-recoverable metal motion transmitting means is mounted external to said boards.
Claim 13
Dependent Claim
39 words
A connector as in claim 11 wherein said first and second boards are provided with a separate biasing means to bias said first board relative to said second board to disengage pins that may be inserted into said openings.
Claim 14
Dependent Claim
85 words
A tool for a connector having an element of heat-recoverable metal, said metal requiring cooling and expansion to operate the connector, the tool comprising: first and second members adapted to thermally and mechanically engage a heat-recoverable metal element of a connector, said members capable of being cooled; and an expansible biasing means interconnecting said members, said members cooling such an element upon engagement and said biasing means expanding to move the members apart from each other to expand such an element when it is cooled.
Claim 15
Dependent Claim
85 words
A tool for a connector having an element of heat-recoverable metal, said metal requiring cooling and expansion to operate the connector, the tool comprising: first and second members adapted to thermally and mechanically engage a heat-recoverable metal element of a connector, said members capable of being cooled; and an expansible biasing means interconnecting said members, said members cooling such an element upon engagement and said biasing means expanding to move the members apart from each other to expand such an element when it is cooled.
