Abstract

Abstract A light weight or miniature fluid actuator stripper crimper machine is disclosed for semi-automatically stripping insulation from the free end of a wire and crimp connecting an electrical terminal on the stripped end of the wire. The subject machine is pneumatically actuated and includes apparatus designed to accomplish the following sequence of functions, namely, gripping of the free end of a wire, cutting and stripping the insulation from the free end of the wire, moving the wire vertically into the open barrel of an electrical terminal, crimping the terminal onto the free end of the wire, freeing the wire from the clamp, and stripping the terminal from the machine. The subject machine is light weight and requires only connection to a source of pressurized air in order to achieve the desired operational sequence.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 271 words
A fluid actuated semi-automatic stripper crimper apparatus for stripping insulation from the free end of a wire and crimp connecting an electrical terminal from a continuous strip of terminals onto the free end of said wire, said apparatus comprising: frame means, wire clamping means mounted on said frame means including a pair of normally spaced clamping blocks and means adapted to drive said blocks together to clampingly secure a wire between said blocks, a stripper assembly including means mounting said assembly in said frame means for horizontal reciprocating motion, wire insulation cutting means, means adapted to drive said cutting means into cutting engagement with the insulation of said wire, and means to drive said assembly axially of said wire to strip a severed slug of insulation therefrom, a bottom tooling assembly disposed behind said wire clamping means and beneath said stripper assembly, said tooling assembly including a fixed anvil and vertically moveable terminal shear means, terminal strip feed means adapted to feed a continuous strip of terminals through said shear means to a position above said anvil, ram means mounted in said frame for vertical reciprocable motion, said ram means including a crimping ram, means adapted to drive said ram into contact with said terminal and at least one die means depending from said ram, and a force cam assembly disposed to drive between an upper portion of said ram and a fixed abutment, after said ram has made initial contact with said terminal, to apply a crimping force to said ram whereby said terminal is severed from its associated carrier strip and crimped to the stripped end of said wire.
Claim 2
Dependent Claim 271 words
A fluid actuated semi-automatic stripper crimper apparatus for stripping insulation from the free end of a wire and crimp connecting an electrical terminal from a continuous strip of terminals onto the free end of said wire, said apparatus comprising: frame means, wire clamping means mounted on said frame means including a pair of normally spaced clamping blocks and means adapted to drive said blocks together to clampingly secure a wire between said blocks, a stripper assembly including means mounting said assembly in said frame means for horizontal reciprocating motion, wire insulation cutting means, means adapted to drive said cutting means into cutting engagement with the insulation of said wire, and means to drive said assembly axially of said wire to strip a severed slug of insulation therefrom, a bottom tooling assembly disposed behind said wire clamping means and beneath said stripper assembly, said tooling assembly including a fixed anvil and vertically moveable terminal shear means, terminal strip feed means adapted to feed a continuous strip of terminals through said shear means to a position above said anvil, ram means mounted in said frame for vertical reciprocable motion, said ram means including a crimping ram, means adapted to drive said ram into contact with said terminal and at least one die means depending from said ram, and a force cam assembly disposed to drive between an upper portion of said ram and a fixed abutment, after said ram has made initial contact with said terminal, to apply a crimping force to said ram whereby said terminal is severed from its associated carrier strip and crimped to the stripped end of said wire.
Claim 3
Dependent Claim 95 words
A stripper crimper apparatus according to claim 1 wherein said wire clamping drive means comprises: a pair of closely spaced, parallel clamp block supporting plates having said blocks fixedly mounted thereon, said plates having a profiled central aperture and being constrained for only horizontal sliding movement, cam means adapted to bring said blocks into clamping engagement, said cam means including a shaft, a double lobed cam fixed on said shaft, with said lobes lying within said apertures in said plates, whereby rotation of said cam within said apertures causes said blocks to be driven together.
Claim 4
Dependent Claim 26 words
A stripper crimper apparatus according to claim 2 wherein said drive means comprises, a pneumatically actuated piston cylinder device operatively connected to rotate said cam shaft.
Claim 5
Dependent Claim 69 words
A stripper crimper apparatus according to claim 3 wherein said drive means further comprises: a first cam plate connected to be driven by said piston cylinder device, a second cam plate connected to be driven by and in a direction normal to the direction of movement of said first cam plate, and crank arm means connected to said cam shaft and to be driven by said second cam plate.
Claim 6
Dependent Claim 70 words
A stripper crimper apparatus according to claim 1 wherein said stripper assembly further comprises: a pair of stripper members overlappingly mounted together in scissor fashion, each said member having a profiled cam slot therein and a cutting blade mounted thereon with said blades in cutting opposition, and means restraining movement of said stripper members to reciprocal motion normal to the longitudinal axis and in the plane of said stripper members.
Claim 7
Dependent Claim 79 words
A stripper crimper apparatus according to claim 5 wherein said stripper assembly cutter drive means comprises: a drive arm having a shaft extending normally therefrom, roller means on the free end of said shaft lying within said cam slots of said stripper members, and a pneumatically actuated piston cylinder device operatively connected to drive said drive arm along its longitudinal axis whereby movement of said rollers in said cam slots causes said cutter blades to be opened and closed.

Dependent Claim 52 words
A stripper crimper apparatus according to claim 6 wherein said stripper assembly drive means comprises: a pneumatically actuated piston cylinder device connected to reciprocally drive the stripper assembly in said frame axially of said wire after the insulation has been cut whereby the severed slug of insulation is stripped from said wire.
Claim 9
Dependent Claim 41 words
A stripper crimper apparatus according to claim 5 wherein said stripper assembly further comprises: wire guide stop means, and means to adjust the positioning of said stop means whereby the length of the slug of insulation to be removed is determined.
Claim 10
Dependent Claim 44 words
A stripper crimper appAratus according to claim 1 wherein said shear means includes a horizontal slot through which said terminal strip passes, said shear means being adapted to be driven downwardly by said ram means to shear each terminal from the associated carrier strip.
