Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
235 words
The combination of a printed circuit board (PCB), a face plate attached to one end of said PCB and a latching mechanism for use in aiding the insertion of said PCB into a mating apparatus, for securing said PCB in said mating apparatus, and for aiding the extraction of said PCB from said mating apparatus, said combination characterized by: said latching mechanism comprising: a body portion; a pair of walls extending from said body portion, facing portions of said walls having means for rotatably mounting said latching mechanism on opposite faces of said face plate, the facing portions of said walls also having facing channels snap locatable onto detents on said opposite faces of said face plate to resiliently latch said latching mechanism when said PCB is fully inserted into said mating apparatus; a camming portion projecting form an end of said body portion, said camming portion adapted to engage a projection on said mating apparatus; and an actuating portion providing leverage for said camming portion; said camming portion and said actuating portion cooperating to function as a lever, said camming portion adapted to engage an inside surface of said projection to establish a first engagement about which said latching mechanism is levered to overcome an insertion force, and adapted to engage an outside surface of said projection to establish a second engagement about which said latching mechanism is levered to overcome an extraction force.
Claim 2
Dependent Claim
235 words
The combination of a printed circuit board (PCB), a face plate attached to one end of said PCB and a latching mechanism for use in aiding the insertion of said PCB into a mating apparatus, for securing said PCB in said mating apparatus, and for aiding the extraction of said PCB from said mating apparatus, said combination characterized by: said latching mechanism comprising: a body portion; a pair of walls extending from said body portion, facing portions of said walls having means for rotatably mounting said latching mechanism on opposite faces of said face plate, the facing portions of said walls also having facing channels snap locatable onto detents on said opposite faces of said face plate to resiliently latch said latching mechanism when said PCB is fully inserted into said mating apparatus; a camming portion projecting form an end of said body portion, said camming portion adapted to engage a projection on said mating apparatus; and an actuating portion providing leverage for said camming portion; said camming portion and said actuating portion cooperating to function as a lever, said camming portion adapted to engage an inside surface of said projection to establish a first engagement about which said latching mechanism is levered to overcome an insertion force, and adapted to engage an outside surface of said projection to establish a second engagement about which said latching mechanism is levered to overcome an extraction force.
Claim 3
Dependent Claim
82 words
The combination as claimed in claim 1 wherein said means for rotatably mounting said latching mechanism is a pair of apertures, one aperture in each wall of said pair of walls, each aperture of said pair of apertures adapted to permit insertion of one pin of a pair of pins on said opposite faces of said face plate, said walls being resiliently flexible to allow said latching mechanism to be assembled over said pins until said pins snap into a respective aperture.
Claim 4
Dependent Claim
39 words
The combination as claimed in claim 1 or 2 wherein said latching mechanism assumes a flush position against said face plate when said PCB is inserted in said mating apparatus and said latching mechanism is in a latched position.
Claim 5
Dependent Claim
72 words
The combination as claimed in claim 1 or 2 further comprising an additional latching mechanism identical to said latching mechanism said latching mechanism and said additional latching mechanism are located at opposite ends of said face plate and oriented such that said actuating portion of said latching mechanism faces said actuating portion of said additional latching mechanism to thereby allow latching to said mating apparatus at opposite ends of said face plate.
