Abstract
Abstract A back panel input/output board for any back panel/plug-in board assembly, often in combination with a rack for holding the boards coupled to the back panel. The wires from the back panel connectors are connected to contact pins on a separate board which is hinged to the back panel. The hinged board, with connector patterns of contact pins, provides external access for inputs to and outputs from the back panel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
207 words
An apparatus comprising: an interconnection board; a back panel having a bottom side and a top side; at least one logic card pluggably connected to said top side of said back panel; hinge means coupling said board to said back panel, said hinge means being so constructed that said board lies in substantially the same plane as said back panel when in the open position for making interconnections between said back panel and said board, and when rotated on said hinge means by 180° to the closed position, said board lies in parallel confronting relationship with said back panel; a first plurality of connecting pins extending from said bottom side of said back panel; a second plurality of connecting pins extending from one side of said board in the same direction and parallel with said first plurality of connecting pins when said board is in the open position; a plurality of discrete wires spaced from said logic card and interconnecting selected pairs of pins, one of said pins of each pair being located on said back panel and the other of said pins being located on said board; and means connected to said interconnection board for pluggably making external input/output connections to said pins in said board.
Claim 2
Independent Claim
207 words
An apparatus comprising: an interconnection board; a back panel having a bottom side and a top side; at least one logic card pluggably connected to said top side of said back panel; hinge means coupling said board to said back panel, said hinge means being so constructed that said board lies in substantially the same plane as said back panel when in the open position for making interconnections between said back panel and said board, and when rotated on said hinge means by 180° to the closed position, said board lies in parallel confronting relationship with said back panel; a first plurality of connecting pins extending from said bottom side of said back panel; a second plurality of connecting pins extending from one side of said board in the same direction and parallel with said first plurality of connecting pins when said board is in the open position; a plurality of discrete wires spaced from said logic card and interconnecting selected pairs of pins, one of said pins of each pair being located on said back panel and the other of said pins being located on said board; and means connected to said interconnection board for pluggably making external input/output connections to said pins in said board.
Claim 3
Dependent Claim
35 words
The apparatus recited in claim 1 and further comprising spacer means located on one of said back panel and said board for maintaining said board spaced from said back panel when in the closed position.
Claim 4
Dependent Claim
42 words
The apparatus recited in claim 1 and further comprising an elongated strain relief bar mounted on one of said back panel and said board for directing said plurality of wires when said board is moved from the open to the closed position.
Claim 5
Independent Claim
27 words
The apparatus recited in any of claims 1-3 wherein at least some of the pins of said second plurality of connecting pins are arranged in discrete arrays.
Claim 6
Independent Claim
38 words
The apparatus recited in any of claims 1-3 wherein at least some of the pins of said second plurality of connecting pins are formed with a socket in one end adapted to receive the pins of a connector.
Claim 7
Independent Claim
38 words
The apparatus recited in any of claims 1-3 wherein at least some of the pins of said second plurality of connecting pins are formed with elongated pins extending from both ends and from both sides of said board.
Claim 8
Dependent Claim
27 words
The apparatus recited in claim 1 wherein when in the closed position said board is in parallel confronting relationship with the bottom side of said back panel.
Claim 9
Dependent Claim

The apparatus recited in claim 4 wherein said pluggable external connection means comprises a connector having pins extending therefrom in one direction and a plurality of wires for external connection extending therefrom in another direction, said pins being coupled with one of said arrays of said second plurality of connecting pins.
Claim 10
Dependent Claim
53 words
The apparatus recited in claim 4 wherein said pluggable external connection means comprises a connector having female connector means on one side thereof and a plurality of wires for external connection extending from another side thereof, said female connector being coupled with one of said arrays of said second plurality of connecting pins.
Claim 11
Dependent Claim
48 words
The apparatus recited in claim 4 wherein the pins in at least some of said arrays are formed with a socket in one end and the pins in others of said arrays are formed with elongated pins extending from both ends and from both sides of said board.
Claim 12
Independent Claim
51 words
The apparatus recited in any of claims 1-3 wherein when in the closed position, said first and second plurality of connecting pins are in spaced confronting relationship and are prevented from mutual interference by the distance between said board and said back panel by said hinge means and said spacer means.
