When the fusion operation is completed, the heat-pressed plate 10 moves upward, and the fused insulating tape 4 is cut by a cutter (not shown).

Thereby, the core wires 3 are arranged and fixed by the insulating tape 4 as shown in FIG.

(Problem to be Solved by the Invention) However, simply arranging the core wire 3 in the arrangement groove 11a of the arrangement jig 11 and heating and fusing the insulating tape 4 will cause an eighth problem.
As shown in the figure, there is a disadvantage that the insulating tape 4 is curved due to the bending of the core wire 3 or the like.

For this reason, the pitch of the core wire 3 fixed by the insulating tape 4 fluctuates.
There is a problem that an I / O cable with a defective connector or the like may be obtained.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a tape fixing device for a cable core wire which can hold the core wires fixedly arranged at a predetermined pitch with an insulating tape. .

(Means for Solving the Problems) The cable fixing device for a cable core wire according to the present invention comprises an arrangement jig in which an insulating tape is pressed onto an arranged core wire via a tape crimping portion. The groove for reinforcing the tape is provided.

(Operation) The core wire of the cable is arranged in the arrangement groove of the arrangement jig, and the insulating tape is pressed against the arranged core wire by the tape crimping portion.

Thereby, a reinforcing rib portion is formed on the insulating tape along the pair of tape reinforcing grooves.

Therefore, the rigidity of the insulating tape is improved, and the core wire can be held and fixed at a predetermined pitch while preventing its bending.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
