Abstract
Abstract This machine applies insulation piercing terminals to a plurality of conductors simultaneously and cuts off the conductors where they extend beyond the barrels of the terminals. A cut-off blade attached to the upper crimping die cuts against an anvil that extends across the tops of the terminals beyond the barrels but under the end portions of the conductors that are to be cut off. The blade cuts against the anvil which is preferably made of brass so that the blade can dent the anvil, and accurate alignment of the blade is therefore unnecessary and the blade can cut even though dull.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
Wire-terminatiNg apparatus including in combination a lower crimping die for supporting an insulation piercing terminal having a barrel portion and another end portion extending beyond the barrel, a cut-off anvil movable into a position overlying the extending end portion of the terminal, an upper crimping die directly above the lower crimping die, a cut-off blade that moves toward and from the anvil, the cut-off blade having a bottom cutting edge in position to sever conductors that extend through the barrel and over said extending end portion of the terminal.
Claim 2
Dependent Claim
89 words
Wire-terminatiNg apparatus including in combination a lower crimping die for supporting an insulation piercing terminal having a barrel portion and another end portion extending beyond the barrel, a cut-off anvil movable into a position overlying the extending end portion of the terminal, an upper crimping die directly above the lower crimping die, a cut-off blade that moves toward and from the anvil, the cut-off blade having a bottom cutting edge in position to sever conductors that extend through the barrel and over said extending end portion of the terminal.
Claim 3
Dependent Claim
40 words
The wire-terminating apparatus described in claim 1 characterized by the anvil being made of material that is substantially softer than the cut-off blade and which is dented by the cut-off blade when said blade severs a conductor on the anvil.
Claim 4
Dependent Claim
84 words
The wire-terminating apparatus described in claim 1 characterized by the lower crimping die holding a plurality of terminals in parallel relation to one another, the upper die having surfaces for crimping the barrel portions of all of the terminals simultaneously, the anvil extending across the extending end portions of all of the terminals, and the cut-off blade having a chisel point wide enough to simultaneously sever a plurality of insulated conductors that project across the extending end portions of the terminals beyond the barrels.
Claim 5
Dependent Claim
23 words
The wire-terminating apparatus described in claim 3 characterized by the cut-off blade being made of steel and the anvil being made of brass.
Claim 6
Dependent Claim
23 words
The wire-terminating apparatus described in claim 4 characterized by the cut-off blade being carbide steel and the anvil being made of hard brass.
Claim 7
Dependent Claim
90 words
The wire-terminating apparatus described in claim 3 characterized by a press with a bed on which the lower crimping die is supported, a ram that moves toward and from the lower crimping die, mechanism that moves the ram through a predetermined stroke, the upper crimping die and the cut-off blade being carried by the ram and movable as a unit therewith, the stroke of the ram being correlated with the position of the lower crimping die to cause the cutting blade to penetrate the anvil by 0.001 to 0.005 inches.
Claim 8
Dependent Claim
42 words
The wire-terminating apparatus described in claim 3 characterized by means that move the upper crimping die through a stroke toward and from the lower crimping die, the cutting blade being connected with the upper crimping die for operation as a unit therewith.
Claim 9
Dependent Claim
23 words
The wire-terminating apparatus described in claim 7 characterized by means for vertically adjusting the cutting blade with respect to the upper crimping die.
Claim 10
Dependent Claim
103 words
The wire-terminating apparatus described in claim 7 characterized by the cutting blade being clamped against a vertical face of the upper crimping die and having a chisel point that slopes away from the upper crimping die so that the cutting edge of the blade is spaced somewhat beyond the vertical face of the upper crimping die and in position to contact with the anvil back from the edge of the anvil when the anvil is in a position with one edge in substantial contact with said vertical face of the upper crimping die as the latter reaches the end of its downward stroke.
Claim 11
Dependent Claim
55 words
The wire-terminating apparatus described in claim 1 characterized by the anvil having a groove formed by the cutting blade therein into which the cutting edge of the cutting blade extends whereby the cutting blade severs the conductors by a combined shearing and compressive cutting action in conjunction with the walls and bottom of the groove.
Claim 12
Dependent Claim
69 words
The wire-terminating apparatus described in claim 3 characterized by the terminals that are insulating piercing terminals being on the lower crimping die, insulated conductors from a cable spread apart with one insulated conductor extending through the barrel portion of each terminal, each insulated conductor having a length extending beyond the barrel portion of its terminal to a conductor-gripping means beyond the terminal for holding the conductor in alignment therewith.
Claim 13
Dependent Claim
50 words
The wire-terminating apparatus described in claim 11 characterized by the terminals being held in the lower crimping die by the anvil, and the anvil extending across the terminals and substantially to the barrels of the terminals, and the conductors extending through the barrels and across the top of the anvil.
