Abstract
Abstract An actuating crank and electrical connector housing lever apparatus which enables (1) the holding and releasing of printed circuit cards, boards or the like, and (2) a convenient transverse insertion or extraction of the cards into and from the housing. The actuating crank features self locking within the lever and, through the camming action designed therein, can move the lever from a latched to an unlatched position or, conversely, by a cranking turn through an arc of approximately 210* .

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
Electrical edge connecting apparatus for printed circuit boards, the combination comprising: a. a base member; b. an electrical pin carrier board attached to the base member and having a plurality of printed circuit board edge connecting pins extending from the board; c. a housing for embracing the connecting pins and for biasing the free ends of the pins into contact with the edge connectors of a printed circuit board inserted between the plurality of contacting pins; d. a lever which supports the housing and which is pivotally attached at one end to the base member and including a depending arm provided with an aperture adapted to receive an actuating crank for moving the lever between latched and unlatched positions; e. a lever-actuating means comprising a crank including a crankshaft, a crank arm, a crank pin, and a head adapted to be moved by tool means for moving the other end of the lever between latched and unlatched positions relative to the base member; f. a guide recess included in said base member functioning to guide the depending arm of the lever between the latched and unlatched positions; and g. a distribution board mounted between said base member and said pin carrier board and adapted to electrically mate with the pins mounted in the pin carrier board.
