Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
136 words
An electrical connector adapted to electrically interconnect first and second circuit path surfaces including a connector body of dielectric material having elastomeric characteristics and containing a plurality of cavities extending therethrough, the body of said connector proximate said cavities having a geometry in conjunction with the elastomeric characteristics of the material to be readily deformable by pressure applied through said surfaces along a longitudinal axis of said cavity, a conductive gel positioned in the said cavity in a volume slightly less than the volume of said cavity when said connector body is in an undeformed condition whereby upon the application of said pressure and deformation of said body, the volume of said cavity is reduced to cause said gel to flow into area engagement with the said surfaces thereby interconnecting electrically said surfaces through said gel.
Claim 2
Dependent Claim
136 words
An electrical connector adapted to electrically interconnect first and second circuit path surfaces including a connector body of dielectric material having elastomeric characteristics and containing a plurality of cavities extending therethrough, the body of said connector proximate said cavities having a geometry in conjunction with the elastomeric characteristics of the material to be readily deformable by pressure applied through said surfaces along a longitudinal axis of said cavity, a conductive gel positioned in the said cavity in a volume slightly less than the volume of said cavity when said connector body is in an undeformed condition whereby upon the application of said pressure and deformation of said body, the volume of said cavity is reduced to cause said gel to flow into area engagement with the said surfaces thereby interconnecting electrically said surfaces through said gel.
Claim 3
Dependent Claim
25 words
The connector of claim 1 wherein each said cavity includes an internal recess adapted to accommodate said gel and hold said gel within said cavity.
Claim 4
Dependent Claim
22 words

Claim 5
Dependent Claim
34 words
The connector of claim 1 wherein each said cavity includes a conductive material therewithin the said gel disposed on each side of said material whereby to reduce the path of resistance through said cavity.
Claim 6
Dependent Claim
41 words
The connector of claim 1 wherein said body includes a lip means surrounding each said cavity and operable to seal said gel within said cavity upon deformation of said body through application of said pressure from said first and second surfaces.
Claim 7
Dependent Claim
47 words
The connector of claim 1 wherein said body includes a thin deformable lip surrounding each said cavity at each end of said cavity to effectively seal said gel within said cavity upon deformation of said body through the application of pressure from said first and second surfaces.
Claim 8
Dependent Claim
18 words
The connector of claim 1 further includes means to compress said body by driving said surfaces relatively together.
Claim 9
Dependent Claim
40 words
The connector of claim 1 wherein the said first surface is a conductive pad on a printed circuit board and the said second surface is a conductive element on a component connected through said connector to said printed circuit board.

Claim 11
Dependent Claim
128 words
An electrical connector adapted to interconnect the conductive paths of an electronic component to a printed circuit board including a body containing a plurality of cavities arranged in an array compatible with the conductive paths of said component and printed circuit board with said body being formed of a thin elastomeric material which is readily deformable and with each said cavity being surrounding by a lip of material adapted to be deformed and to seal said cavity upon deformation between said component and said board, a conductive gel substantially filling each said cavity whereby upon deformation of said body and said lip the said gel is caused to flow into engagement with the contact paths of the said component and the said board to provide and interconnection therebetween.
Claim 12
Dependent Claim
128 words
An electrical connector adapted to interconnect the conductive paths of an electronic component to a printed circuit board including a body containing a plurality of cavities arranged in an array compatible with the conductive paths of said component and printed circuit board with said body being formed of a thin elastomeric material which is readily deformable and with each said cavity being surrounding by a lip of material adapted to be deformed and to seal said cavity upon deformation between said component and said board, a conductive gel substantially filling each said cavity whereby upon deformation of said body and said lip the said gel is caused to flow into engagement with the contact paths of the said component and the said board to provide and interconnection therebetween.
Claim 13
Dependent Claim
54 words
The connector of claim 10 whereby the said interior surfaces of the said cavities are provided with characteristics having a wetability to said gel greater than the wetability of the pads of said component and board whereby to preclude sticking of said gel to the said pads and retain said gel within said cavities.
Claim 14
Dependent Claim
21 words
The connector of claim 10 wherein said cavities are deformable to accommodate compression of said gel during deformation of said body.
