Removable high density connector

Claim 2

An electrical connector comprising: overlapping layers of flexible film insulated from each other, each said layer carrying electrically conductive traces, and each said layer having differing and sufficient length to make individual contact with connection pads on a printed circuit board surface, connector pins passing through said layers, selective electrical connections between said pins and said traces, cylindrical elastometric bodies having parallel spaced apart conductors thereon, and a quality of said bodies corresponding to the quantity of said layers wherein, said conductors simultaneously engage said traces and said pads.

Claim 3

An electrical connector as recited in claim 1 wherein said selective electrical connections are soldered joints and the connector further comprising a rigid backing plate impinging said pins and resisting axial movement of said pins relative to said joints between said pins and said traces.

Claim 4

An electrical connector as recited in claim 1 and further comprising: (a) a housing having framed openings to receive said bodies and to align said bodies with said traces and said pads, (b) latches projecting from a surface of said housing, (c) a compression member fittably mounted within said housing causing said bodies to engage said pads, (d) a retaining member mating with said latches and removably securing said housing, said bodies, and said compression member to the printed circuit board.

Claim 5

An electrical connector as recited in claim 3 wherein said selective electrical connections are soldered joints and the connector further comprising a rigid backing plate impinging said pins and resisting axial movement of said pins relative to said joints between said pins and said traces.

Claim 6

An electrical connector as recited in claim 1 wherein, traces in a layer extend between pads in a row farthest from a connector edge of the printed circuit board and pins forming a row closest to said pads and traces in subsequent layers extend between pads forming subsequent rows and pins forming subsequent rows.

Claim 7

An electrical connector as recited in claim 1 wherein, pins carrying signal potential are adjacent to pins carrying reference potential.

Claim 8

A removable surface mounted edge connector comprising: (a) at least one layer of flexible film, (b) conductive traces carried within each said layer, (c) connection pads on a printed circuit board surface, (d) each said layer having a differing and sufficient length for said traces to make individual contact with said pads, (e) at least one cylindrical elastomeric body having parallel spaced apart conductors thereon wherein, said conductors simultaneously engage said traces and said pads, (f) a housing having at least one framed opening to receive said bodies and to align said bodies with said traces and said pads, (g) latches projecting from a surface of said housing, (h) a compression member fittably mounted within said housing compressing said bodies and causing said conductors to engage said pads, and (i) at least one retaining member mating with said latches and removably securing said housing, said bodies, and said compression member to a printed circuit board.

Claim 9

A removable surface mounted edge connector comprising: (a) at least one layer of flexible film, (b) conductive traces carried within each said layer, (c) connection pads on a printed circuit board surface, (d) each said layer having a differing and sufficient length for said traces to make individual contact with said pads, (e) at least one cylindrical elastomeric body having parallel spaced apart conductors thereon wherein, said conductors simultaneously engage said traces and said pads, (f) a housing having at least one framed opening to receive said bodies and to align said bodies with said traces and said pads, (g) latches projecting from a surface of said housing, (h) a compression member fittably mounted within said housing compressing said bodies and causing said conductors to engage said pads, and (i) at least one retaining member mating with said latches and removably securing said housing, said bodies, and said compression member to a printed circuit board.

Claim 10

An electrical connector as recited in claim 7 and further comprising: (a) first and second retaining members removably secured to the printed circuit board with bolts extending through said retaining members, (b) a rigid backing plate with sidewalls at opposite ends, and (c) spring members on either side of each said sidewall that receive said retaining members and bias said retaining members away from each other.

Claim 11

An electrical connector as recited in claim 7 and further comprising: (a) pins passing through said layers, (b) selectively soldered joints between said traces and pins in said pins, and (c) a rigid backing plate impinging said pins and resisting axial movement of said pins relative to said joints.
