Injector/ejector device for circuit board

Claim 1

An injection/ejection device to aid in the entry and removal of an object from a mating apparatus, said device comprising: a lever with a bifurcated portion, said portion, being rotatably attached to the ends of a pivot pin; bracket means slidably mounted onto said pivot pin within said bifurcated portion and further comprising means for rotatably mounting the device onto the object; anchor means fixedly attached within said bifurcated portion to said pivot pin and further having engagement means to attach the object to the apparatus at an opposite end; first means for generating an outwardly directed linear force within said object; and second means for generating an inwardly directed linear force within the object, whereby the object may be injected into and ejected from the apparatus.

Claim 17

A method of injecting a printed circuit board (PCB) having a face plate on a front edge and a plug on a rear edge thereof into a receiving card cage having a socket which matably engages said plug comprising: A. providing an injection/ejection device to aid in the entry and removal of said PCB from said receiving card cage said device comprising a lever with a bifurcated portion, said bifurcated portion comprising a pair of arms each mounted to an end of a pivot pin and having an eccentric arcuate surface at an inner corner adapted to bear upon said PCB, at least one of said arms having a spur on its inner side, said bifurcated portion being rotatably attached to the ends of said pivot pin; a bracket means comprising an aperture having a first elongated portion oriented parallel to an anchor means through which said pivot pin passes and an enlarged second portion having an upper bearing surface, said second portion being positioned to receive said spur; said bracket means slidably mounted onto said pivot pin within said bifurcated portion and further comprising a means for rotatably mounting the device onto the PCB; said anchor means fixedly attached within said bifurcated portion to said pivot pin and further having engagement means to attach the PCB to the receiving card cage at an opposite end; a first means for generating an outwardly directed linear force within said PCB, said first force generating means comprises having said spur oriented within said second aperture portion such that a first rotation of said lever arm will cause an upper surface of said spur to contact eccentrically an upper one of said aperture bearing surfaces and generate said outwardly directed linear force whereby the PCB is ejected from the receiving card cage; a second means for generating an inwardly directed linear force within the PCB wherein said second force generating means comprises a placement of said arcuate surface such that upon a second rotation of said lever arm opposite to said first rotation, said arcuate surface will eccentrically contact and bear upon the PCB to generate said inwardly directed linear force whereby the PCB is injected into the receiving card cage; B. rotatably mounting said device onto the face plate; C. inserting the PCB into the receiving card cage until the plug contacts the socket; D. rotating said lever arm so as to generate an outwardly directed linear force causing said bracket and face plate to move outward relative to said anchor means; E. rotating said device around said anchor means until said engagement means slips into and reciprocally engages a mounting hole in a front frame member of the receiving card cage; and F. reverse rotating said lever arm so as to generate an inwardly directed linear force causing the PCB to move inward and cause the plug to mate with said socket.

Claim 18

A method of injecting a printed circuit board (PCB) having a face plate on a front edge and a plug on a rear edge thereof into a receiving card cage having a socket which matably engages said plug comprising: A. providing an injection/ejection device to aid in the entry and removal of said PCB from said receiving card cage said device comprising a lever with a bifurcated portion, said bifurcated portion comprising a pair of arms each mounted to an end of a pivot pin and having an eccentric arcuate surface at an inner corner adapted to bear upon said PCB, at least one of said arms having a spur on its inner side, said bifurcated portion being rotatably attached to the ends of said pivot pin; a bracket means comprising an aperture having a first elongated portion oriented parallel to an anchor means through which said pivot pin passes and an enlarged second portion having an upper bearing surface, said second portion being positioned to receive said spur; said bracket means slidably mounted onto said pivot pin within said bifurcated portion and further comprising a means for rotatably mounting the device onto the PCB; said anchor means fixedly attached within said bifurcated portion to said pivot pin and further having engagement means to attach the PCB to the receiving card cage at an opposite end; a first means for generating an outwardly directed linear force within said PCB, said first force generating means comprises having said spur oriented within said second aperture portion such that a first rotation of said lever arm will cause an upper surface of said spur to contact eccentrically an upper one of said aperture bearing surfaces and generate said outwardly directed linear force whereby the PCB is ejected from the receiving card cage; a second means for generating an inwardly directed linear force within the PCB wherein said second force generating means comprises a placement of said arcuate surface such that upon a second rotation of said lever arm opposite to said first rotation, said arcuate surface will eccentrically contact and bear upon the PCB to generate said inwardly directed linear force whereby the PCB is injected into the receiving card cage; B. rotatably mounting said device onto the face plate; C. inserting the PCB into the receiving card cage until the plug contacts the socket; D. rotating said lever arm so as to generate an outwardly directed linear force causing said bracket and face plate to move outward relative to said anchor means; E. rotating said device around said anchor means until said engagement means slips into and reciprocally engages a mounting hole in a front frame member of the receiving card cage; and F. reverse rotating said lever arm so as to generate an inwardly directed linear force causing the PCB to move inward and cause the plug to mate with said socket.
