Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
An improved cantilevered circuit card guide of the type to be attached at its base to a connector block, and having a pair of oppositely facing parallel slots each adapted to receive an edge of a circuit card and permit it to slide therein toward the connector block, wherein the improvement comprises a) a tongue on the base end projecting approximately transverse to the directions faced by the slots and contacting the connector block when attached thereto, and b) a pair of projections on the base end, defining between them a groove oppositely facing from the tongue, and contacting the connector block when attached thereto, and allowing the tongue on an identical circuit card guide attached adjacent the groove with its tongue facing it, to project into the groove.
Claim 2
Dependent Claim
129 words
An improved cantilevered circuit card guide of the type to be attached at its base to a connector block, and having a pair of oppositely facing parallel slots each adapted to receive an edge of a circuit card and permit it to slide therein toward the connector block, wherein the improvement comprises a) a tongue on the base end projecting approximately transverse to the directions faced by the slots and contacting the connector block when attached thereto, and b) a pair of projections on the base end, defining between them a groove oppositely facing from the tongue, and contacting the connector block when attached thereto, and allowing the tongue on an identical circuit card guide attached adjacent the groove with its tongue facing it, to project into the groove.
Claim 3
Dependent Claim
14 words
The article of claim 1, wherein the groove is substantially parallel to the slots.
Claim 4
Dependent Claim
20 words
The article of claim 2, wherein the bottom of the groove is substantially parallel to the sides of the slots.
Claim 5
Dependent Claim
20 words
The article of claim 1 wherein the width of the tongue is slightly less than the width of the groove.
Claim 6
Dependent Claim
86 words
The card guide of claim 1, further comprising a. a circuit card connector panel having a plurality of connector blocks aligned side by side, and having spaced groups of connectors, the space between groups being wider than the base of the card guide measured along the direction faced by a slot, and at least one hole between the groups; and b. mounting means passing through the hole in the space between groups of connectors for detachably mounting the card guide by its base in said space.
