Abstract
Abstract Apparatus for semiautomatic termination of conductors of a ribbon cable to electrical terminals of an electrical connector having conductor receiving cavities located on opposite sides thereof. In operation the apparatus combs and shears individual conductors of the ribbon cable. The comb means cooperates with the individual conductors adjacent the dielectric jacket of the cable, ensuring that the individual conductors will be combed and spaced as required for termination to the terminals. The shear means is retracted, leaving the comb means in contact with the conductors, maintaining the position of the conductors until the connector is brought into place. A shuttle then places the connector in engagement with the conductors. The comb means is retracted, permitting the conductors to be positioned in alignment with terminating sections of the terminals which in turn allows for insertion and crimping of the conductors to occur. A unique feature of this assembly is that as the conductors are sheared, they are also preformed to enable the connector to be easily inserted along the preformed conductors.

Claim 1
Independent Claim
229 words
An apparatus for terminating conductors of an electrical cable to terminating sections of electrical terminals disposed in a dielectric housing of an electrical connector having conductor receiving passages therein, the apparatus comprising: clamp means to maintain the cable in proper position; comb means which cooperate with the conductors of the cable such that as the comb means is moved between a first position and a second position, the comb means spaces the conductors of the cable; shearing means which cooperate with the conductors such that as the shearing means is moved between a first and second position, conductors are sheared and ends of the conductors are preformed; shearing blades are provided on the shearing means, the shearing blades shear the conductors as the shearing means is moved from the first position toward the second position, the shearing blades continue past the plane of the conductors until the second position is reached, thereby forming the conductors accordingly; shuttle means having the connector located therein, the shuttle being movable between a front and a back position; whereby as the shuttle is moved from the back position to the front position, the tapered surfaces of conductor receiving passages of the connector cooperate with the preformed ends of the conductors so as to position the ends of the conductors in alignment with terminating sections of the terminals of the connector for termination thereto.
