Abstract
Abstract A connector arrangement for making connections between printed circuit boards and connectors located on parallel side panels such as the side panels of a card cage of a computer central processing unit. The printed circuit boards are part of modules which include a retractable connector arrangement. The connectors are moved to a retracted position in which their width is less than the spacing between connectors on the side panels to facilitate their insertion between the side panels. Once in position, the modules are moved to an extended position and connections are made between the modules connectors and those on the side panels. The connectors provide low cost, high reliability, high density connections and facilitate close center-to-center spacings between adjacent modules.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
181 words
A printed circuit board module for connection to a pair of spaced parallel stationary panels having connectors thereon, comprising: rigid printed circuit board means for supporting electronic circuits; a first connector set means coupled to a first edge of the printed circuit board means, for making electrical connections between the printed circuit board means and the connectors on one panel; and a second connector set means, coupled to a second edge of the printed circuit board means which is opposite the first edge, for making electrical connections between the printed circuit board means and the connectors on the other panel, and first and second connector set means being movable with respect to one another in the direction of the plane of the circuit board means from a retracted position which enables the module to be inserted between the panels to an extended position in which the connector set means are coupled to the connectors of the panels, wherein the second connector set means remains coupled to the edge of the printed circuit board means in both the retracted and extended positions.
Claim 2
Dependent Claim
181 words
A printed circuit board module for connection to a pair of spaced parallel stationary panels having connectors thereon, comprising: rigid printed circuit board means for supporting electronic circuits; a first connector set means coupled to a first edge of the printed circuit board means, for making electrical connections between the printed circuit board means and the connectors on one panel; and a second connector set means, coupled to a second edge of the printed circuit board means which is opposite the first edge, for making electrical connections between the printed circuit board means and the connectors on the other panel, and first and second connector set means being movable with respect to one another in the direction of the plane of the circuit board means from a retracted position which enables the module to be inserted between the panels to an extended position in which the connector set means are coupled to the connectors of the panels, wherein the second connector set means remains coupled to the edge of the printed circuit board means in both the retracted and extended positions.
Claim 3
Dependent Claim
58 words
A printed circuit board module according to claim 1 wherein the printed circuit board means comprises a single printed circuit board, the first connector set means is mounted to the printed circuit board in a fixed position and the second connector set means is mounted so that it is movable toward and away from the printed circuit board.
Claim 4
Dependent Claim
27 words
A printed circuit board module according to claim 2 including a flexible connector set electrically connected between the printed circuit board and the second connector set means.
Claim 5
Dependent Claim
32 words
A printed circuit board module according to claim 3 including a mounting frame slidably attached to the printed circuit board, wherein the second conductor set means is secured to the mounting frame.
Claim 6
Dependent Claim
70 words
A printed circuit board module according to claim 4 in combination with a pair of spaced parallel panels having connectors thereon, and a plurality of fasteners for securing the first and second connector set means to the connectors on the panels, wherein one or more fasteners is initially connected between a panel and the mounting frame and is tightened to move the second connector set means to its extended positions.
Claim 7
Dependent Claim
18 words
The combination according to claim 5 including biasing means for biasing the mounting frame toward the retracted position.
Claim 8
Dependent Claim
18 words
The combination according to claim 5 including biasing means for biasing the mounting frame toward the retraction position.
Claim 9
Dependent Claim
34 words
The combination according to claim 1 or 5, including release means for forcing the mounting frame away from an adjacent panel to thereby disconnect the second connector set means from the associated panel connectors.
Claim 10
Dependent Claim
222 words
A card cage and printed circuit board assembly useful in computer systems, comprising: a card cage comprising a main frame having first and second parallel side panels located a fixed distance apart from one another, each of the side panels having a plurality of electrical connector sets secured thereto in a parallel fashion; and a plurality of printed circuit board modules carried within the card cage, wherein each of the modules comprises: a rigid printed circuit board; a first connector set means secured to one edge of the printed circuit board, said first connector set means being connected to a connector set of the first side panel, a second connector set means movably secured to the edge of the printed circuit board opposite the first connector set means, said second connector set being movable in the direction of the plane of the circuit board from a retracted position which enables the module to be inserted into the card cage to an extended position in which the second connector set means is coupled to a corresponding connector set of the second side panel, wherein the second connector set means remains coupled to the edge of the printed circuit board means in both the retracted and extended positions; and a flexible connector electrically connecting the second connector set means to the printed circuit board.
Claim 11
Dependent Claim
222 words
A card cage and printed circuit board assembly useful in computer systems, comprising: a card cage comprising a main frame having first and second parallel side panels located a fixed distance apart from one another, each of the side panels having a plurality of electrical connector sets secured thereto in a parallel fashion; and a plurality of printed circuit board modules carried within the card cage, wherein each of the modules comprises: a rigid printed circuit board; a first connector set means secured to one edge of the printed circuit board, said first connector set means being connected to a connector set of the first side panel, a second connector set means movably secured to the edge of the printed circuit board opposite the first connector set means, said second connector set being movable in the direction of the plane of the circuit board from a retracted position which enables the module to be inserted into the card cage to an extended position in which the second connector set means is coupled to a corresponding connector set of the second side panel, wherein the second connector set means remains coupled to the edge of the printed circuit board means in both the retracted and extended positions; and a flexible connector electrically connecting the second connector set means to the printed circuit board.
Claim 12
Dependent Claim
46 words
An assembly according to claim 9 including a plurality of fasteners secured between the printed circuit board modules and the side panels, wherein tightening of the fasteners will cause the first and second connector set means to couple with corresponding connector sets on the side panels.
Claim 13
Dependent Claim
31 words
An assembly according to claims 9 or 10 including guide means for guiding the first and second connector set means so that they properly mate with the side panel connector sets.
