Abstract
Abstract A handle for a printed circuit card is provided with a slot for accepting the card, with keyed contacts at the edge of the card projecting into the slot. The card is permanently fastened to the handle by rivets. A plurality of spaced, substantially parallel holes extend through the handle from its front surface to a point of intersection with the slot to expose the contacts on the card. Separate indicator units and control units are slidably received in respective ones of the holes and are frictionally retained therein with spring-loaded terminals of the units electrically contacting the keyed contacts on the printed circuit card. A further array of keyed contacts at the opposite edge of the card is adapted to mate with a female connector when the card is inserted into position in a card shelf, the handle being exposed with legends and indicator units visible thereon and with control units accessible for selective exercise of control on the operation of the circuit carried by the card.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
229 words
A printed circuit card holder for retaining a card having keyed terminals associated with the printed circuit carried by said card adjacent at least two edges of said card, said holder comprising: an electrically insulative body member having four sides, opposite pairs of which are substantially parallel to one another, and having two ends; a pair of electrically insulative ribs projecting in spaced parallel relation from and substantially perpendicular to one of said sides of said body and defining a slot therebetween of width sufficient to accept the thickness of said printed circuit card and the thickness of the printed circuit carried by said card, said slot extending partly into said body member at said side from which said ribs project; a plurality of spaced substantially parallel holes extending through said body member from the side opposite said side from which said ribs project and intersecting the portion of the slot extending into said body; a printed circuit card in said slot and fastened to said ribs with the keyed terminals at one edge of said card exposed in at least some of said holes intersecting said slot; and control and display means mating with respective ones of said some of said holes and having electrical connectors electrically contacting keyed terminals at said one edge of said card for electrical interaction with the circuit carried by said fastened card.
Claim 2
Dependent Claim
229 words
A printed circuit card holder for retaining a card having keyed terminals associated with the printed circuit carried by said card adjacent at least two edges of said card, said holder comprising: an electrically insulative body member having four sides, opposite pairs of which are substantially parallel to one another, and having two ends; a pair of electrically insulative ribs projecting in spaced parallel relation from and substantially perpendicular to one of said sides of said body and defining a slot therebetween of width sufficient to accept the thickness of said printed circuit card and the thickness of the printed circuit carried by said card, said slot extending partly into said body member at said side from which said ribs project; a plurality of spaced substantially parallel holes extending through said body member from the side opposite said side from which said ribs project and intersecting the portion of the slot extending into said body; a printed circuit card in said slot and fastened to said ribs with the keyed terminals at one edge of said card exposed in at least some of said holes intersecting said slot; and control and display means mating with respective ones of said some of said holes and having electrical connectors electrically contacting keyed terminals at said one edge of said card for electrical interaction with the circuit carried by said fastened card.
Claim 3
Dependent Claim
34 words
The card holder according to claim 1 further including a surface contour at each of said ends to facilitate gripping of the holder for transfer of the associated card from one position to another.
Claim 4
Dependent Claim
23 words
The card holder according to claim 1 wherein said control and display means are slidably insertable into and slidably removable from said holes.
Claim 5
Dependent Claim
222 words
A printed circuit card holder for retaining a card having keyed terminals associated with the printed circuit carried by said card adjacent at least two edges of said card, said holder comprising: an electrically nonconductive handle having a front edge and a rear edge; a slot in said rear edge of said handle sufficiently wide to accept a printed circuit card; a plurality of spaced-apart holes extending in a substantially parallel array through said handle from said front edge to said rear edge and intersecting said slot; a printed circuit card fastened in said slot with the keyed terminals along one edge of said card projecting toward said front edge of said handle and exposed in at least some of said holes intersecting said slot; and a plurality of control and display means slidably engaged in respective ones of said some of said holes, via said front edge of said handle for selective withdrawal from said front edge, and having electrical connectors electrically contacting the keyed terminals at said one edge of said card exposed in said holes for electrical interaction with the circuit carried by the fastened card, said control and display means being fixedly mounted relative to said card for electrical operation therewith and said electrical connectors continuously cOntacting the respective keyed terminals at said one edge of said card.
Claim 6
Dependent Claim
222 words
A printed circuit card holder for retaining a card having keyed terminals associated with the printed circuit carried by said card adjacent at least two edges of said card, said holder comprising: an electrically nonconductive handle having a front edge and a rear edge; a slot in said rear edge of said handle sufficiently wide to accept a printed circuit card; a plurality of spaced-apart holes extending in a substantially parallel array through said handle from said front edge to said rear edge and intersecting said slot; a printed circuit card fastened in said slot with the keyed terminals along one edge of said card projecting toward said front edge of said handle and exposed in at least some of said holes intersecting said slot; and a plurality of control and display means slidably engaged in respective ones of said some of said holes, via said front edge of said handle for selective withdrawal from said front edge, and having electrical connectors electrically contacting the keyed terminals at said one edge of said card exposed in said holes for electrical interaction with the circuit carried by the fastened card, said control and display means being fixedly mounted relative to said card for electrical operation therewith and said electrical connectors continuously cOntacting the respective keyed terminals at said one edge of said card.
Claim 7
Dependent Claim
44 words
The combination according to claim 4 wherein said control means comprises switch means for selectively electrically connecting and disconnecting portions of the circuit carried by said card via the respective keyed terminals with which the electrical connectors of the respective control means make contact.
Claim 8
Dependent Claim
44 words
The combination according to claim 4 wherein said display means comprises indicator means for detecting and displaying the operating state of a portion of the circuit coupled to the respective keyed terminals with which the electrical connectors of the respective display means make contact.
Claim 9
Dependent Claim
38 words
The combination according to claim 4 wherein said control means comprises means for selectively modifying the operation of the circuit coupled to the respective keyed terminals with which the electrical connectors of the respective control means make contact.
