Abstract

PURPOSE:To automate insertion of a wire in a groove of insulating substance by sensing electrical contacting of the core of wire with a cutter from the sensing voltage impressed at one end of the core, and locating the insulating substance so that the wire insert hole is in alignment with a guide groove. CONSTITUTION:Pushing a start switch 14 is sensed by a sensor circuit 26, and upon receipt of the sensing signal, a controller 33 slides a placing table 4 with the aid of a driver circuit 31 through a control circuit 32. This placing table 4 moves a connector cover 3 until it stops at a groove 2 situated below a wire guide groove 10. A voltage impression circuit 25 impresses a specified voltage on each wire of a connector 19a. If wire 18 at the other end of a cable 19 is grasped and pressed to a continuity cutter 13, it cuts the insulator on the wire 18 to cause the core inside of it to be in electrical contact with the cutter 13. The controller 33 senses this contacting through a sensor circuit 29 to know the position where the wire 18 is arranged, and the placing table 4 is moved by the driver circuit 31 so as to locate the groove 2 below the wire guide groove 10. The operator inserts the wire 18 into the guide groove 10.

The mounting table 4 moves the connector cover 3 toward the housing 8 and stops with the groove 2 positioned below the wire guide groove 10.

A connector 19a is connected in advance to one end of the cable 19 by connecting wires I8 at one end of the cable 19 to contacts (not shown) in an arbitrary arrangement. Then, when connecting the connector to the end of the cable 19, the wire alignment device of the present invention is used to match the wire arrangement of the connector 19a.

That is, under the control of the controller 33, the voltage application circuit 25 sequentially applies a predetermined voltage to each wire 18 of the connector 19a through its contacts at high speed. In this state, the two workers are using the wire 18 at the other end of the cable 19
