Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A retaining device for card edge connectors which receive circuit cards having a slot in one side thereof and which are inserted into the connector with the slot being at a predetermined distance therefrom, said retaining device comprising an elongated, U-shaped member formed from spring wire and having parallel legs joined at one end by a bight and having free ends pivotally attached to the connector at one end thereof, said legs including parallel concavo-convex shaped portions between said bight and said free ends whereby the length of said member may be resiliently elongated to a predetermined length to enable said bight to be placed in the slot in the circuit card which may be placed in the connector and thereby exert a retaining force on the circuit card to hold it in the connector.
Claim 2
Dependent Claim
135 words
A retaining device for card edge connectors which receive circuit cards having a slot in one side thereof and which are inserted into the connector with the slot being at a predetermined distance therefrom, said retaining device comprising an elongated, U-shaped member formed from spring wire and having parallel legs joined at one end by a bight and having free ends pivotally attached to the connector at one end thereof, said legs including parallel concavo-convex shaped portions between said bight and said free ends whereby the length of said member may be resiliently elongated to a predetermined length to enable said bight to be placed in the slot in the circuit card which may be placed in the connector and thereby exert a retaining force on the circuit card to hold it in the connector.
Claim 3
Dependent Claim
21 words
The retaining device of claim 1 wherein the free ends are inwardly turned and are received in holes in the connector.
Claim 4
Dependent Claim
24 words
The retaining device of claim 2 wherein said free ends are deflected towards the convex side of said concavo-convex shaped portion of said legs.
Claim 5
Dependent Claim
26 words
The retaining device of claim 3 with said deflection being at an angle of about ninety degrees relative to the general longitudinal axis of said legs.
