Disclosed is a device for insertion and removal of a circuit board into a mating connector positioned within a housing, the device having a first end for pivotal engagement with the circuit board and adapted to mate with a front surface of the housing when the circuit board to which the device is pivotally engaged begins to engage the connector, and a second end disposed longitudinally from the first end and adapted with a latch for releasably mating with a protrusion on the board such that when the board is engaged with the connector the second end becomes releasably mated to the protrusion thereby latching the board to the connector.

What is claimed is: 1. A device for insertion and removal of a circuit board into a mating connector, said connector positioned within a housing, said device comprising: a first end for pivotal engagement with said circuit board, said first end also adapted to mate with a front surface of said housing when said circuit board to which said device is pivotally engaged begins to engage said connector; a second end disposed longitudinally from said first end, said second end adapted with a latch having a slot for releasably mating with a protrusion on said circuit board such that when said board is engaged with said connector said second end becomes releasably mated to said protrusion thereby latching said board to said connector wherein said first end and said second end are part of one continuous member of said device; and wherein said slot engages said board protrusion, said slot having a notch for mating with said board protrusion, said notch allowing for over travel of said circuit board during mating of said board into said mating connector while serving to lock said board in said mated relationship with said connector. 2. The device of claim 1 wherein an outer surface of said latch accepts a reapplication of insertion force to release said mating relationship. 3. The device of claim 1 further comprising a finger tab for allowing a user to exert said force on said device. 4. The device of claim 1 wherein said first end pivotal engagement is permanent. 5. A method of locking a printed wiring board into a connector, said connector mounted to a housing, said housing having at least one guide for positioning said board with respect to said connector, said method comprising: placing a board within said guide in a direction such that said board will, upon the application of insertion force thereupon, move into mated relationship with said connector; applying said insertion force to said board to move said board toward said connector until a first end of a device which is pivotally mounted to said board engages with an edge of said housing; rotating said device so that a longitudinal portion of said device engages on a portion of said board; continuing to apply force to said device so as to move said board and said connector into said mated relationship; retaining said device in an engaged position on said portion of said board, even after said external insertion force has been removed, said engaged position maintaining a force to bias said board into said connector and preventing said board from becoming disconnected from said connector at least in part by said first end of said device engaging said edge of said housing; and briefly reapplying a force in the direction of said insertion force to an outer edge of said device to release said maintained engaged position. 6. The method of claim 5 comprising: pivotally rotating said device outward, thereby allowing said board to become disconnected from said connector. 7. The method of claim 5 wherein said retaining step includes providing positive feed-back to a user that said engaged position is being maintained. 8. A device for locking a printed wiring board (PWB) into a connector, said connector mounted to a housing, said housing having at least one guide for positioning said board with respect to said connector, said device comprising: means for applying an external insertion force to said PWB to move said PWB toward said connector along said guide, said means having a first end pivotally attached to said PWB board, said first end having a portion for engaging with a portion of said housing; means for contacting a front edge of said PWB along a longitudinal portion of said device; means for maintaining at least a portion of said insertion force so that said means for contacting said front edge maintains a force to bias said PWB into said connector after said external insertion force has been removed; and means operative upon the reapplying of said external insertion force for releasing said maintained positive force. 9. The device of claim 8 wherein said maintaining means includes an over-center latch. 10. The device of claim 8 wherein said maintaining means includes a pin mounted permanently to said board. 11. A latching device for use with housing accepting a plurality of electronic boards into mating relationship with a plurality of connectors affixed to said housing, said housing having at least one locking portion for mating with said latching device pivotally mounted on at least one electronic board, said latching device comprising: means for applying an external insertion force to an electronic board of said plurality of electronic boards to move said electronic board toward a corresponding connector of said plurality of connectors along a guide, said means having a first end pivotally attached to said board, said first end having a portion for engaging with a portion of said housing; means for contacting a front edge of said electronic board along a longitudinal portion of said device; means for maintaining at least a portion of said insertion force so that said means for contacting said front edge maintains a force to bias said electronic board into said connector after said external insertion force has been removed; and means operative upon the reapplying of said external insertion force for releasing said maintained positive force. 12. A device for aiding in latching an electronic circuit board in a mated relationship with an electrical connector, said connector located at a back end of a housing, said device comprising: a first end for engaging a front surface of said housing; means for pivoting said first end around an outer corner of a circuit board to be latched; a second end disposed laterally from said first end said second end comprising a latch mechanism for releasably latching to a pin mounted on said board wherein operation of said latch mechanism provides over travel of said electronic circuit board during mating of said electronic circuit board into said electrical connector; and a body extending between said ends, said body having upper and lower portions separated by a distance to allow at least a portion of said board to fit between said portions when said latch mechanism is latched to said pin. 13. The device of claim 12 further comprising: a spring located between said upper and lower portions and operable for providing outward force on said device when said device is latched to said pin. 14. The device of claim 13 wherein said latching mechanism further comprising: a slide for contacting said pin and for directing said pin to a notch within said mechanism. 15. The device of claim 14 wherein said latching mechanism further comprises a stop for preventing said pin from reaching said notch which insertion pressure is executed on said device. 16. The device of claim 15 wherein said spring encourages said latching mechanism to move so that said pin may enter said notch when said insertion pressure is removed from said device. 17. The device of claim 16 wherein said latching mechanism includes a second spring for encouraging said latch to rotate such that said latch becomes disengaged from said pin.
