ABSTRACT:
Apparatus for inserting a plurality of insulated conductors in respective insulation piercing portions of contacts of an electrical device employs an electrically operable programmer for selectively controlling movement of a carriage along the electrical device, for example an electrical connector, and for controlling the insertion of conductors on each side of the device. The carriage is mounted for movement along the connector and is selectively programmed to stop at rest insertion positions at which insertion tools are operated to insert and terminate the conductors. The conductors are moved in the general direction of the insulation piercing portions of the contacts, manually and under tension, and are received by guide means which accurately align and position the conductors adjacent the respective contact portions. Each insertion tool includes two blades which are movable together toward the electrical connector. One of the blades normally extends beyond the other to slightly pre-insert a portion of a conductor into a strain relief member adjacent the contact portion prior to cutting and insertion of the conductor into the insulation piercing contact portion. The strain relief insertion blade is biased toward its extended position and movable with respect to the other insertion blade so as to have its forward end aligned with the forward end of the other blade for simultaneous and complete insertion of the conductor into the contact portion and the strain relief member after initial partial pre-insertion and cutting have occurred. Individual conductors of a pair of conductors may be simultaneously inserted on opposite sides of a connector, or sequentially on the same side of a connector by selection of double-sided or single-sided modes of operation. Also, connectors of different widths may be safely contacted without contact damage. A visual indicator is provided to indicate the position of a contact being terminated.
