Abstract
Abstract Apparatus for coupling the stripped free end of a ribbon cable with a connector comprising a fixed recipient block having a slot for the receipt of the striped and bent wires of a ribbon cable; reciprocable blocks located on opposite sides of the fixed recipient block with crimping fingers secured thereto and reciprocal through apertures in the fixed recipient block; and means to move the reciprocable blocks and crimping fingers toward each other into the slot for effecting the mechanical coupling of the connector housing locate din the slot with at least some of the stripped wires. Also disclosed is the method of coupling connectors to the free ends of cables with such apparatus.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
146 words
A method for attaching the conductor wires of the stripped free end of a ribbon cable to an electrical connector comprising the steps of: positioning the stripped free end in a guide member; providing a coupling fixture having a fixed recipient block with a slot for the initial receipt of a connector housing and for the subsequent receipt of the stripped free end, the coupling fixture having crimping fingers reciprocable toward and away from the slot to effect the bending of at least a portion of the connector into crimping engagement with at least some of the wires to thereby couple the connector to the wires; and moving the crimping fingers between an inoperative orientation whereat the crimping fingers are remote from the slot and an operative orientation whereat the crimping fingers are adjacent to the slot for the crimping of the connector onto the wires.
Claim 2
Independent Claim
146 words
A method for attaching the conductor wires of the stripped free end of a ribbon cable to an electrical connector comprising the steps of: positioning the stripped free end in a guide member; providing a coupling fixture having a fixed recipient block with a slot for the initial receipt of a connector housing and for the subsequent receipt of the stripped free end, the coupling fixture having crimping fingers reciprocable toward and away from the slot to effect the bending of at least a portion of the connector into crimping engagement with at least some of the wires to thereby couple the connector to the wires; and moving the crimping fingers between an inoperative orientation whereat the crimping fingers are remote from the slot and an operative orientation whereat the crimping fingers are adjacent to the slot for the crimping of the connector onto the wires.
Claim 3
Dependent Claim
55 words
The method as set forth in claim 1 and further including the step of gripping that portion of the connector which had been crimped and moving that portion of the connector which had been crimped with respect to the connector housing whereby the remaining wires are brought into contact with other portions of the connector.
Claim 4
Dependent Claim
67 words
The method as set forth in claim 1 wherein the portion of the connector which is crimped is a ground bus and the wires which are crimped to the ground bus are unbent ground wires and further including the step of gripping the ground bus and moving the ground bus relative to the connector housing whereby the remaining non-ground wires are brought into contact with signal contacts.
Claim 5
Dependent Claim
111 words
For use in association with apparatus for terminating the free end of a ribbon cable, apparatus for coupling the stripped free end of a ribbon cable with a connector comprising: a fixed recipient block having a slot for the receipt of the stripped and bent wires of a ribbon cable; reciprocable blocks located on opposite sides of the fixed recipient block with crimping fingers secured thereto and reciprocal through apertures in the fixed recipient block; and means to move the reciprocable blocks and crimping fingers toward each other into the slot for effecting the mechanical coupling of the connector located in the slot with at least some of the stripped wires.
Claim 6
Dependent Claim
111 words
For use in association with apparatus for terminating the free end of a ribbon cable, apparatus for coupling the stripped free end of a ribbon cable with a connector comprising: a fixed recipient block having a slot for the receipt of the stripped and bent wires of a ribbon cable; reciprocable blocks located on opposite sides of the fixed recipient block with crimping fingers secured thereto and reciprocal through apertures in the fixed recipient block; and means to move the reciprocable blocks and crimping fingers toward each other into the slot for effecting the mechanical coupling of the connector located in the slot with at least some of the stripped wires.
Claim 7
Dependent Claim
60 words
The coupling apparatus as set forth in claim 4 wherein the slot is of a size and shape to receive a connector housing prior to the receipt of the free end of the ribbon cable, the connector housing having electrically conductive signal contacts and an electrically conductive bus bar slidingly received within an electrically insulating portion of the connector housing.
Claim 8
Dependent Claim
53 words
The coupling apparatus as set forth in claim 5 wherein the means to move the reciprocal blocks and crimping fingers includes primary handles rotatable about axes parallel with the width of the cable and located on opposite sides thereof whereby the crimping fingers move perpendicularly with respect to the plane of the cable.
Claim 9
Dependent Claim
45 words
The coupling apparatus as set forth in claim 6 and further including pinching fingers located on opposite sides of the bus bar of the connector to hold the bus bar against movement after the crimping fingers have crimped the bus bar to the ground wires.
Claim 10
Dependent Claim
38 words
The coupling apparatus as set forth in claim 7 and further including secondary handles mounted on an axis parallel with the first axes to move the pinching fingers into and out of pinching engagement with the bus bar.
Claim 11
Dependent Claim
71 words
The coupling apparatus as set forth in claim 8 and further including tertiary handles to urge the connector housing away from the pinching fingers while the pinching fingers are in engagement with the bus bar whereby the connector housing will slide with respect to the pinched ground bus to drive the signal contacts of the connector housing into contact with bent wires of the ribbon cable which have not been pinched.
Claim 12
Dependent Claim
25 words
The coupling apparatus as set forth in claim 9 wherein the pinched wires are unbent ground wires and the other wires are bent signal wires.
Claim 13
Dependent Claim
69 words
The wire bending apparatus as set forth in claim 4 wherein the cable to be terminated is supported in a guide member with a taper in the edge thereof which supports the stripped free end of the cable and wherein the edge of the slot of the fixed recipient block which is adapted to receive guide member is tapered for matingly receiving the guide member in a precise orientation.
