Abstract
Abstract A three part card guide for attachment to a host circuit card has opposing guide rails to receive transverse edges of an auxiliary circuit card. The guide rails attach to either end of a connector support which holds a first electrical connector and an auxiliary circuit card may be slid between the guide rails so that a second electrical connector along its rearward edge engages the first electrical connector. The guide rails and connector support assembly have hooks, to attach them to the host circuit card, which may be engaged with longitudinal motion of the assembly. The electrical connector, when attached to the host card through the connector support, prevents such longitudinal motion, locking the assembly in place.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
An auxiliary card system for holding a generally rectangular auxiliary printed circuit card parallel to a host circuit card, the host card including slots, comprising: guide means extending parallel to a first and second opposed edge of the auxiliary circuit card for slideably receiving the first and second edges of the auxiliary circuit card along an insertion axis and including hook means for attaching the guide means to the host circuit card the hook means for engaging the slots by extending through the slots and capturing the host circuit card between the upper surface of the hook means and a lower surface of the guide means when the guide means is moved along the insertion axis; connector means attached to and extending along a third edge of the auxiliary circuit card for electrically connecting the auxiliary circuit card to the host circuit card by means of conductors received by the host circuit card; and connector support extending parallel to the third edge of the auxiliary circuit card for receiving and supporting the connector means the connector support attached to the guide means to prevent relative motion along the insertion axis therebetween, and the connector support interfitting with the conductors to prevent motion of the conductor support along the insertion axis when the conductors are received by the host circuit board.
Claim 2
Dependent Claim
220 words
An auxiliary card system for holding a generally rectangular auxiliary printed circuit card parallel to a host circuit card, the host card including slots, comprising: guide means extending parallel to a first and second opposed edge of the auxiliary circuit card for slideably receiving the first and second edges of the auxiliary circuit card along an insertion axis and including hook means for attaching the guide means to the host circuit card the hook means for engaging the slots by extending through the slots and capturing the host circuit card between the upper surface of the hook means and a lower surface of the guide means when the guide means is moved along the insertion axis; connector means attached to and extending along a third edge of the auxiliary circuit card for electrically connecting the auxiliary circuit card to the host circuit card by means of conductors received by the host circuit card; and connector support extending parallel to the third edge of the auxiliary circuit card for receiving and supporting the connector means the connector support attached to the guide means to prevent relative motion along the insertion axis therebetween, and the connector support interfitting with the conductors to prevent motion of the conductor support along the insertion axis when the conductors are received by the host circuit board.
Claim 3
Dependent Claim
37 words
The auxiliary card support system recited in claim 1 wherein the hook means engage the slots when the connector support means is moved along the insertion axis in the direction the auxiliary circuit card is slideably received.
Claim 4
Dependent Claim
60 words
The auxiliary card support system recited in claim 2 wherein the connector support has second hook means for engaging the slots by extending through the slots and capturing the host circuit card between the upper surface of the second hook means and a lower surface of the connector support when the connector support means is moved along the insertion axis.
Claim 5
Dependent Claim
46 words
The auxiliary card support system recited in claim 2 wherein the connector support means is attached to the guide means by an interlocking tab for permitting the guide means to be removed from the connector support by relative motion therebetween other than along the insertion axis.
Claim 6
Dependent Claim
55 words
The auxiliary card support of claim 1 wherein the lower surface of the guide means includes stabilizer surfaces extending perpendicular to the insertion axis for flexing downward against the host circuit card when the hook means are engaged with the slots to prevent disengagement of the guide means from the edges of the auxiliary card.
Claim 7
Dependent Claim
105 words
An extraction system for an auxiliary circuit card said card being removable in a longitudinal forward direction, said extraction system comprising: a faceplate having outer dimensions conforming substantially to that of a rectangular prism and for attaching to one edge of the auxiliary card, the face plate having a back face with a flanking perpendicular face; an extraction tool having parallel prongs; and a first and second recess forming a cavity in the back face and presenting an opening at the flanking perpendicular edge along the back face sized for receiving the parallel prongs of the extraction tool but not for admitting a human finger.
