Claim 3

The cabinet in accordance with claim 1 including means for mechanically mounting said first set of printed circuit boards to retain said first set of boards in fixed relation to each other.

Claim 4

The cabinet construction in accordance with claim 2 wherein each of said slides includes conducting tracks and contact members and means for selectively positioning said contacts in preparation for insertion and removal of the associated printed circuit board by zero insertion and removal force.

Claim 5

A cabinet for electrical or electronic equipment, comprising a casing, a plurality of support means, horizontal slides formed within the lateral walls of said casing and for slideably receiving said support means, said support means comprising sets of further slides arranged in pairs, means for opening said contact members during insertion into or extraction from said connector of an associated printed circuit board, said connectors forming the slide being carried by said casing and making electrical contact with conducting tracks formed on the horizontally disposed printed circuit board on the peripheral portions adjacent said lateral edges, said connectors forming the slides on the horizontally disposed printed circuit boards being in turn electrically connected to the conducting tracks on that particular board, and wherein each said board guide is operatively secured to an associated connector in the horizontally disposed printed circuit board.

Claim 6

A cabinet for electrical or electronic equipment, comprising a casing, a plurality of support means, horizontal slides formed within the lateral walls of said casing and for slideably receiving said support means, said support means comprising sets of further slides arranged in pairs, means for opening said contact members during insertion into or extraction from said connector of an associated printed circuit board, said connectors forming the slide being carried by said casing and making electrical contact with conducting tracks formed on the horizontally disposed printed circuit board on the peripheral portions adjacent said lateral edges, said connectors forming the slides on the horizontally disposed printed circuit boards being in turn electrically connected to the conducting tracks on that particular board, and wherein each said board guide is operatively secured to an associated connector in the horizontally disposed printed circuit board.

Claim 7

In combination with a cabinet as claimed in claim 4, a printed circuit board having on one of its faces, a series of connectors forming slides adapted each to receive therein the edges of a vertically disposed printed circuit board, and further including a set of board guides, each adapted to receive the opposite edge of one of the vertically disposed boards therein.

Claim 8

The cabinet construction in accordance with claim 4 in which at least one of the lateral walls of said casing includes a set of board guides adapted to receive the edges of the horizontally disposed printed circuit board and such wall is constituted by distinct printed circuit board.

Claim 9

The cabinet configuration in accordance with claim 4 in which at least two of the vertical walls comprising said casing are constructed of printed circuit boards having complementary board guides positioned in a manner receiving the edges of an associated horizontally disposed printed circuit board, and including zero insertion force means forming slides for said horizontally disposed printed circuit boards.

Claim 10

The cabinet construction in accordance with claim 7 including grandmother boards operatively fixed to said frame, means forming connector slides on said vertically disposed grandmother boards, and adapted to receive the complementary edges of horizontally disposed mother boards therein through printed circuit means on said grandmother boards and daughter boards.

Claim 11

A cabinet for electrical or electronic equipment, comprising a casing, a plurality of support means, horizontal slides formed within the lateral walls of said casing and for slideably receiving said support means, said support means comprising sets of further slides arranged in pairs, means for opening said contact members during insertion into or extraction from said connector of an associated printed circuit board, said connectors forming the slide being carried by said casing and making electrical contact with conducting tracks formed on the horizontally disposed printed circuit board on the peripheral portions adjacent said lateral edges, said connectors forming the slides on the horizontally disposed printed circuit boards being in turn electrically connected to the conducting tracks on that particular board, and wherein each said board guide is operatively secured to an associated connector in the horizontally disposed printed circuit board, and in which third printed circuit boards form vertical walls of said casing and include zero insertion force connectors forming slides for said horizontally disposed printed circuit boards.

Claim 12

A cabinet for electrical or electronic equipment, comprising a casing, a plurality of support means, horizontal slides formed within the lateral walls of said casing and for slideably receiving said support means, said support means comprising sets of further slides arranged in pairs, means for opening said contact members during insertion into or extraction from said connector of an associated printed circuit board, said connectors forming the slide being carried by said casing and making electrical contact with conducting tracks formed on the horizontally disposed printed circuit board on the peripheral portions adjacent said lateral edges, said connectors forming the slides on the horizontally disposed printed circuit boards being in turn electrically connected to the conducting tracks on that particular board, and wherein each said board guide is operatively secured to an associated connector in the horizontally disposed printed circuit board, and in which third printed circuit boards form vertical walls of said casing and include zero insertion force connectors forming slides for said horizontally disposed printed circuit boards.
