The cable 19 from which the plurality of connecting coated wires 18 are led out from one end is held by the cable holding means (not shown) in the space central portion 4a of the mounting table 4, and the motors 16 and 17 are the same as the pressing member 7. It is fixed at a predetermined position in the housing 8.

1 and a receiving connector 23 into which the connector 22a at one end of the control cable 22 led out from the wire insertion device 1 is inserted.
It is attached to the outer surface of 4.

A control circuit as shown in FIG. 2 is incorporated in the control device 20, and a voltage application circuit 25 such as a scanner circuit for sequentially applying a constant voltage to each of the wires 18 and a start S.

FIG. 1 shows a state in which the connector cover 3 is attached to the mounting table 4, and when the operator pushes the start SW 14, the detection circuit 26 detects it and the controller 33 which receives the detection signal passes through the motor control circuit 32. Drive the motor drive circuit 31 by
The mounting table 4 slides accordingly. In this start state, the mounting table 4 moves the connector cover 3 in the direction of the housing 8 and stops when the groove 2 is located below the wire guide groove 10.

A connector 19a is pre-connected to one end of the cable 19, and the wire 18 at one end of the cable 19 is connected to a contact (not shown) in an arbitrary arrangement. When connecting the connector to the end of the cable 19, the connector 19a
The wire aligner of the present invention is used to match the wire placement of the.

That is, the voltage applying circuit is controlled by the controller 33.
The reference numeral 25 sequentially applies a predetermined voltage to each wire 18 of the connector 19a at high speed via its contacts. In this state, the operator holds the wire 18 at the other end of the cable 19 and presses it against the conductive cutter 13, so that the cutter 13 cuts the insulating coating of the wire 18 to electrically connect the wire core wire and the cutter 13 therein. They are brought into contact with each other (state shown by finger A in FIG. 1). The controller 33 detects this electrical contact via the continuity detection circuit 29, and the controller 33
Can know the arrangement position of the wires 18 to which the voltage is applied in the connector 19a.

Along with that, the mounting table 4 slides, and the connector cover 3
The groove 2 corresponding to the connector 19a is moved so as to be located below the wire guide groove 10. At that time, one of the lamps 9 is displayed to inform the operator which of the pair of connector covers 3 is to be used.

As a result, the operator inserts the wire 18 into the wire guide groove 10 indicated by the lamp 9 (the state shown by the finger B in FIG. 1), and the wire set detection SW 15
To operate. When the controller 33 that detects this switch operation via the circuit 27 drives the motor drive circuit 30 via the motor control circuit 32, the pressing member 7 descends and the pushing piece 6 causes the wire 18 in the wire guide groove 10 to move. Is pushed into the groove 2, and the extra length of the end of the wire 18 is cut by the cutter tooth 5.

By this series of operations, the wire placement position is the same as that of the connector 19a attached to one end of the cable 19, the other end of the wire 18 is inserted into the groove 2 of the connector cover 3, and then the cover is pressed against the housing with contacts. By doing so, a cable with connectors at both ends is completed.

A relatively low speed rotation (for example, 30 rpm) is performed by 41, and the rotation stop of the motor 31 is controlled by a cutter motor control circuit 42 provided in the control device 20 and connected to the controller 33.

The motor 41 driven by the control circuit 42 rotates when the core wire of the wire 18 and the cutter 13 are not in electrical contact,
Detection circuit 29 for the electrical contact between the core wire of 18 and the cutter 13.
When the controller 33 detects via the
Drives the motor drive circuit 31 via the motor control circuit 32, slides the mounting table 4 accordingly, and moves so that the groove 2 corresponding to the connector 19a of the connector cover 3 is located below the wire guide groove 10. At the same time, the rotation of the motor 41 is stopped via the control circuit 42.

In this way, the cutter 13 rotates, and this rotation stops when the cutter 13 makes electrical contact with the wire core, and its device is to prevent the cutting edge of the cutter 13 from coming into contact with the wire core too strongly. The wire core wire is prevented from being damaged by the contact, and is particularly effective for the thin wire 18.
