Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A circuit card biasing device for card edge connectors of the type having a sloping passage at one end of a card receiving slot, said device comprising body means for being slidably received in the sloping passage, nose means attached to and projecting from said body means for extending into the slot, a surface on said nose means for engaging a side of a circuit card inserted into the slot to thereby bias the card against a far end wall of the slot and spring means attached to and extending from said body means for resiliently engaging a backplane on which the connector may be mounted to thereby urge said body means in the passage away from said backplane.
Claim 2
Dependent Claim
119 words
A circuit card biasing device for card edge connectors of the type having a sloping passage at one end of a card receiving slot, said device comprising body means for being slidably received in the sloping passage, nose means attached to and projecting from said body means for extending into the slot, a surface on said nose means for engaging a side of a circuit card inserted into the slot to thereby bias the card against a far end wall of the slot and spring means attached to and extending from said body means for resiliently engaging a backplane on which the connector may be mounted to thereby urge said body means in the passage away from said backplane.
Claim 3
Dependent Claim
25 words
The biasing device of claim 1 further including retaining means on said body means for cooperating with the passage to retain said body means therein.
Claim 4
Dependent Claim
12 words
The biasing device of claim 1 made by stamping and forming processes.
Claim 5
Dependent Claim
33 words
The biasing device of claim 1 wherein said body means and said surface on said nose means are at a relative angle to each other ranging from about seven to about thirty degrees.
Claim 6
Dependent Claim
30 words
The biasing device of claim 1 wherein said body means and said surface on said nose means are at an angle of twelve and one-half degrees relative to each other.
Claim 7
Dependent Claim
25 words
The biasing device of claim 1 wherein said biasing device further includes ramp means located over said nose means and leading to said surface thereon.
Claim 8
Dependent Claim
32 words
The biasing device of claim 1 wherein said spring means is curved and includes an arcuate shaped free end with the convex surface thereof adapted to engage the surface of the backplane.
Claim 9
Dependent Claim
128 words
A circuit card biasing device for card edge connectors of the type having a sloping passage at one end of a card receiving slot, said device comprising body means of a conductive material for being slidably received in the sloping passage, nose means attached to and projecting from said body means for extending into the slot, a surface on said nose means for engaging a side of a circuit card inserted into the slot to thereby bias the card away from the passage, spring means for urging said body means towards one end of the passage and a grounding contact arm, attached to said body means, extending into the slot, and having a free end adapted to slidingly engage a ground trace on a surface of the card.
Claim 10
Dependent Claim
128 words
A circuit card biasing device for card edge connectors of the type having a sloping passage at one end of a card receiving slot, said device comprising body means of a conductive material for being slidably received in the sloping passage, nose means attached to and projecting from said body means for extending into the slot, a surface on said nose means for engaging a side of a circuit card inserted into the slot to thereby bias the card away from the passage, spring means for urging said body means towards one end of the passage and a grounding contact arm, attached to said body means, extending into the slot, and having a free end adapted to slidingly engage a ground trace on a surface of the card.
Claim 11
Dependent Claim
31 words
The biasing device of claim 8 further including grounding means on said body means for engaging a ground trace on a backplane on which the card edge connectors may be mounted.
