Abstract
Abstract Connector apparatus for making contact with a printed circuit board includes a pair of resilient spring contact members which are brought into contact with opposite sides of a printed circuit board by, in one embodiment, rotation of the printed circuit board generally about an axis parallel to the inserted edge thereof, and in another embodiment, by the edge of the printed circuit board being brought into contact with and moving a body having rollers mounted thereto which contact the resilient spring contact members to force them against the opposite sides of the printed circuit board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A connector apparatus for a printed circuit board comprising: a base; a first resilient contact member secured to and extending from said base: a second resilient contact member secured to and extending from said base, said second resilient contact member spaced from said first resilient contact member; a body; means operatively connected with the body and the contact members for providing that as a printed circuit board edge is inserted between the contact members to contact and move the body, the resilient contact members are urged and moved against the resilience thereof to bring portions thereof into contact with the respective opposite sides of the printed circuit board, wherein the means operatively connected with the body and contact members comprise first and second rollers rotatably mounted to the body, the contact members extending between the first and second rollers.
Claim 2
Dependent Claim
139 words
A connector apparatus for a printed circuit board comprising: a base; a first resilient contact member secured to and extending from said base: a second resilient contact member secured to and extending from said base, said second resilient contact member spaced from said first resilient contact member; a body; means operatively connected with the body and the contact members for providing that as a printed circuit board edge is inserted between the contact members to contact and move the body, the resilient contact members are urged and moved against the resilience thereof to bring portions thereof into contact with the respective opposite sides of the printed circuit board, wherein the means operatively connected with the body and contact members comprise first and second rollers rotatably mounted to the body, the contact members extending between the first and second rollers.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein the resilient contact members define respective curved portions in turn defining respective seats in which the first and second rollers seat respectively with a printed circuit board removed from between the contact members.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 wherein the curved portions are brought into contact with the respective opposite sides of an inserted printed circuit board.
