Abstract
Abstract An electronic circuit card extender for providing mechanical as well as etrical interfacing of a printed circuit card or board in an electronic system to its corresponding mating plug on a chassis. The circuit card extender comprises a frame having etching or wiring on one side thereof, to extend the configuration of electrical connections from the circuit card to the corresponding plug on the chassis and a pair of bushings used for keying purposes. Each bushing is mounted on a rotatable shaft which extends along the body of the extender frame to the plug or the chassis connector at one end and has a keying pin at the other end thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A circuit card extender for transferring the electrical connections of a printed circuit of an electronic system from a chassis connector in a congested chassis area thereof to a convenient testing area which comprises: an elongated frame having a first and a second longitudinal sides and a first and a second lateral sides; a plurality of male electrical connectors mounted on said first lateral side; a plurality of female electrical connectors mounted on said second lateral side; means for connecting each member of said plurality of male electrical connectors to a corresponding member of said plurality of female electrical connectors; a first elongated shaft rotatably mounted along said first longitudinal side of said frame; a second elongated shaft rotatably mounted along said second longitudinal side of said frame; keying means at both ends thereof for each of said first and second elongated shafts; and guiding means for coupling said frame to the chassis connector of the electronic system.
Claim 2
Dependent Claim
158 words
A circuit card extender for transferring the electrical connections of a printed circuit of an electronic system from a chassis connector in a congested chassis area thereof to a convenient testing area which comprises: an elongated frame having a first and a second longitudinal sides and a first and a second lateral sides; a plurality of male electrical connectors mounted on said first lateral side; a plurality of female electrical connectors mounted on said second lateral side; means for connecting each member of said plurality of male electrical connectors to a corresponding member of said plurality of female electrical connectors; a first elongated shaft rotatably mounted along said first longitudinal side of said frame; a second elongated shaft rotatably mounted along said second longitudinal side of said frame; keying means at both ends thereof for each of said first and second elongated shafts; and guiding means for coupling said frame to the chassis connector of the electronic system.
Claim 3
Dependent Claim
20 words
