Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
253 words
A shielded connector block including an insulating body having an elongate nose, a nose flange to either end of the nose, circuit board flanges on either side of the body joining the nose flanges, and a plurality of terminal recesses extending from the face of the nose through the body; terminals in the terminal recesses for making electrical connections with contacts inserted through the face of the nose and into the ends of the recesses; a unitary metal radio frequency interference ground shield including a mounting plate on the nose flanges, a barrel extending outwardly from the plate and surrounding the nose, and mounting lugs extending from the plate at opposite ends of the barrel; each lug including a flange cover extending across the adjacent nose flange, a nose flange mounting tab on the back of the nose flange and a circuit board flange mounting tab extending at right angles from the nose flange mounting tab on top of a circuit board flange; mounting holes extending through the plate, the nose flanges, circuit board flanges, the circuit board flange mounting tabs and the nose flange mounting tabs; means for connecting the shield to ground circuitry, whereby the shield may be physically secured to the body by mounting means extending through the mounting holes in the plate, nose flanges and nose flange mounting tabs and the block may be secured to a circuit board by mounting means extending through the mounting holes in the circuit board flange mounting tabs and the circuit board flanges.
Claim 2
Dependent Claim
253 words
A shielded connector block including an insulating body having an elongate nose, a nose flange to either end of the nose, circuit board flanges on either side of the body joining the nose flanges, and a plurality of terminal recesses extending from the face of the nose through the body; terminals in the terminal recesses for making electrical connections with contacts inserted through the face of the nose and into the ends of the recesses; a unitary metal radio frequency interference ground shield including a mounting plate on the nose flanges, a barrel extending outwardly from the plate and surrounding the nose, and mounting lugs extending from the plate at opposite ends of the barrel; each lug including a flange cover extending across the adjacent nose flange, a nose flange mounting tab on the back of the nose flange and a circuit board flange mounting tab extending at right angles from the nose flange mounting tab on top of a circuit board flange; mounting holes extending through the plate, the nose flanges, circuit board flanges, the circuit board flange mounting tabs and the nose flange mounting tabs; means for connecting the shield to ground circuitry, whereby the shield may be physically secured to the body by mounting means extending through the mounting holes in the plate, nose flanges and nose flange mounting tabs and the block may be secured to a circuit board by mounting means extending through the mounting holes in the circuit board flange mounting tabs and the circuit board flanges.
Claim 3
Dependent Claim
63 words
A connector block as in claim 1 wherein the shield includes two circuit board tabs extending from the plate at opposite ends of the barrel and at right angles from the plate beneath the circuit board flanges; and mounting holes formed in the circuit board tabs in alignment with the mounting holes in the circuit board flanges and circuit board flange mounting tabs.
Claim 4
Dependent Claim
30 words
A connector block as in claim 2 wherein said lugs extend from the longitudinal ends of the plate and the flange covers overlie the longitudinal ends of the nose flanges.
Claim 5
Dependent Claim
30 words
A connector block as in claim 3 wherein said shield to ground connecting means comprises the surface of one circuit board tab located away from the adjacent circuit board flange.
Claim 6
Dependent Claim
30 words
A connector block as in claim 3 including a recess in the shield plate between the circuit board tabs for preventing solder from wicking beneath the block during wave soldering.
Claim 7
Dependent Claim
112 words
A stamped metal radio frequency interference preform for mounting on a connector block; the preform including a flat plate, an extruded barrel projecting from one side of the plate and extending axially along the plate, and an L-shaped mounting lug on each end of the plate; each lug including a flange end cover joining an end of the plate, a nose flange mounting tab joining the cover outwardly of the end of the plate and a circuit board flange mounting tab joining the nose flange mounting tab on one edge thereof; mounting holes formed through the ends of the plate, the circuit board flange mounting tabs and the nose flange mounting tabs.
Claim 8
Dependent Claim
112 words
A stamped metal radio frequency interference preform for mounting on a connector block; the preform including a flat plate, an extruded barrel projecting from one side of the plate and extending axially along the plate, and an L-shaped mounting lug on each end of the plate; each lug including a flange end cover joining an end of the plate, a nose flange mounting tab joining the cover outwardly of the end of the plate and a circuit board flange mounting tab joining the nose flange mounting tab on one edge thereof; mounting holes formed through the ends of the plate, the circuit board flange mounting tabs and the nose flange mounting tabs.
Claim 9
Dependent Claim
46 words
A preform as in claim 6 including circuit board tabs extending from one edge of the plate adjacent the ends thereof; said circuit board flange mounting tabs and circuit board tabs both extending in the same direction; and mounting holes formed through the circuit board tabs.
Claim 10
Dependent Claim
104 words
A preform as in claim 7 including crease lines formed at the junctions between the plate and flange end covers, the flange end covers and the nose flange mounting tabs, the nose flange mounting tabs and the circuit board flange mounting tabs and the plate and the circuit board tabs; the crease lines at the flange end covers extending in a direction perpendicular to the longitudinal axis of the barrel and the crease lines at the mounting tabs extending parallel to the longitudinal axis of the barrel; all of said crease lines being on the other side of the preform, away from the barrel.
