The insulated core wires 3 are arranged at predetermined positions of the connector 10 by a robot and connected to the slot terminals at those positions, and this operation is performed for all the insulated core wires 3.

[Problem to be solved by the invention 1 However, in such a fiber arrangement automatic identification method,
Since each insulated core wire 3 must be supplied to the robot one by one for identification, there is a problem that the work efficiency of core wire identification is low.

An object of the present invention is to provide an automatic fiber arrangement identification method for a multi-core cable that can efficiently identify the arrangement order of each insulated core wire.

[Means for Solving the Problems 1] The means of the present invention for achieving the above object will be explained with reference to FIGS. 1 to 7 corresponding to the embodiments. Each of the insulated core wires 3 is first temporarily fixed in a random arrangement to the randomly arranged core wire temporary fixing jig 11, and the random arrangement order of each of the insulated core wires 3 is adjusted to the base end side of the multi-core pull 2.
