Claim 2

A connection device for connecting strip conductors of a flat tape-like cable in face-to-face contact with respective conductor tracks on a first side of a printed circuit board, including a first member for engaging said cable across its width, a second corresponding member for engaging a side of said printed circuit board reverse of said first side, and means for applying pressure to said first member to establish a pressure connection between the conductors of said cable and said respective conductor tracks, the pressure applying means also acting between said first member and said second member so as to spread the pressure across the width of the printed circuit board, said first member being formed with projections registering with said strip conductors on a side of said cable opposite the side making said face-to-face contact, so as to concentrate the pressure in the region of said projections, said connection device further comprising an elastomeric pressure pad formed with openings through which said projections can extend to engage said cable.

Claim 3

A connection device according to claim 1, comprising locating members spaced apart by a distance greater than the width of the cable and extending from said first member engaging said cable or a backing member, so as to pass through corresponding holes in said printed circuit board and co-operate with said second member.

Claim 4

A connection device according to claim 1, wherein said second member is rigidly connected to, and spaced apart from, a further member, such that the space accommodates an assembly of said cable and printed circuit board, said further member being formed with an opening through which pressure is applied to said cable.

Claim 5

A connection device according to claim 3, comprising a backing member for applying pressure to said first member engaging said cable, said backing member being formed with latches for engaging corresponding surfaces on said further member.

Claim 6

A connection device for connecting strip conductors of a flat tape-like cable to respective conductor tracks on a first side of a printed circuit board, including a first member for engaging said cable across its width, a second corresponding member for engaging a side of said printed circuit board reverse of said first side, and means for applying pressure to said first member to establish a pressure connection between the conductors of said cable and said respective conductor tracks, the pressure applying means also acting between said first member and said second member so as to spread the pressure across the width of the printed circuit board, wherein said first member has spaced conductors projecting from opposite sides thereof with respective ends for engagement with said strip conductor of said cable and with a corresponding conductor track on said printed circuit board, and said means for applying pressure includes a backing member acting on said cable to press it against said first member and hence to press said first member against said printed circuit board, said spaced conductors of said first member comprising conductive metals balls of diameter slightly greater than the thickness of said first member.

Claim 7

A connection device for connecting strip conductors of a flat tape-like cable to respective conductor tracks on a first side of a printed circuit board, including a first member for engaging said cable across its width, a second corresponding member for engaging a side of said printed circuit board reverse of said first side, and means for applying pressure to said first member to establish a pressure connection between the conductors of said cable and said respective conductor tracks, the pressure applying means also acting between said first member and said second member so as to spread the pressure across the width of the printed circuit board, wherein said first member has spaced conductors projecting from opposite sides thereof with respective ends for engagement with said strip conductor of said cable and with a corresponding conductor track on said printed circuit board, and said means for applying pressure includes a backing member acting on said cable to press it against said first member and hence to press said first member against said printed circuit board, said spaced conductors of said first member comprising conductive metals balls of diameter slightly greater than the thickness of said first member.

Claim 8

A connection device according to claim 5, wherein said first member consists essentially of an insulating sheet with seatings for receiving said conductive metal balls as a press fit.

Claim 9

A connection device according to claim 5, comprising an elastomeric pressure pad between said backing member and said cable.

Claim 10

A connection device according to claim 5, wherein said backing member and said second member are held together by bolts.

Claim 11

A connection device for connecting respective strip conductors of first and second flat tape-like cables to conductor tracks on opposite sides of a double-sided printed circuit board, the device including first and second members for engaging said first and second cables, respectively, across their widths, and means whereby said first and second cables are pressed into electrical contact with said printed circuit board via said first and second members, wherein each of said first and second members has spaced conductors projecting from opposite sides thereof with respective ends for engagement with said respective strip conductors and with corresponding conductor tracks on said printed circuit board, said spaced conductors comprising metals balls of diameter slightly greater than the thickness of said first member and said second members, respectively.

Claim 12

A connection device for connecting respective strip conductors of first and second flat tape-like cables to conductor tracks on opposite sides of a double-sided printed circuit board, the device including first and second members for engaging said first and second cables, respectively, across their widths, and means whereby said first and second cables are pressed into electrical contact with said printed circuit board via said first and second members, wherein each of said first and second members has spaced conductors projecting from opposite sides thereof with respective ends for engagement with said respective strip conductors and with corresponding conductor tracks on said printed circuit board, said spaced conductors comprising metals balls of diameter slightly greater than the thickness of said first member and said second members, respectively.

Claim 13

A connection device according to claim 9, wherein said first member and said second member each consists essentially of an insulating sheet with seatings for receiving said conductive metal balls as a press fit.

Claim 14

A connection device according to claim 9, comprising elastomeric pressure pads respectively between said first member and said first cable, and between said second member and said second cable.
