Traditionally, this work was done as follows. Using a comb-shaped core wire holder 7 having a large number of core wire positioning insertion portions 6 at equal pitches to the pitches of the respective insulation displacement terminals 2A and 3A as shown in FIG. Each of the core wires 5 is arranged in the insertion portion 6 according to its wire number, and then each of the core wires 5 that have been arranged is arranged into two core groups 5 on the left and right from the center.
Separate the fiber groups 5A and 5B into tapes by sandwiching them from above and below with adhesive tape while maintaining the pitch, and fix the pitch. Connect wires to each insulation displacement terminal 2 of each terminal row 2 and 3 of multi-core connector 1 in pairs.
The connection work was done all at once by press-fitting into A and 3A as shown in Figure 6.

[Problems to be Solved by the Invention] However, when the wire holder 7 as shown in FIG. , since the length of each core wire 5 aligned on both ends is long, when each core wire 5 is connected to the multi-core connector 1 as shown in FIG. 6, the axis of the multi-core cable 4 and the multi-core The center of the connector 1 did not match, resulting in a connection that was biased to one side, which caused problems such as difficulty in inserting it into a case or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a semi-automatic wire arrangement device for a multi-core cable that can symmetrically connect each core wire to a multi-core connector.

[Means for Solving the Problems] To explain the configuration of the present invention for achieving the above object, the present invention provides a core wire for identifying the wire number of an arbitrary core among the convergent wires of a multi-core cable. an identifier, and a plurality of core wires provided on the terminal side of the multi-core cable and facing each other at positions around the axis of the end of the multi-core cable and allowing the identified core wire to pass through while guiding it. A guide section, a display means for displaying the core wire guide section into which the core wire is to be inserted at that time based on identification wire number data given from the core wire identifier, and a large number of core wire positioning insertion sections. Based on the identification wire number data given from the fiber identifier, each fiber holder provided on the outlet side corresponding to each of the fiber guide portions is set to the fiber positioning insertion portion for that wire number. The wire holder positioning mechanism includes a wire holder positioning mechanism that positions and moves the wire holder so as to be on standby corresponding to the outlet of the wire guide portion, and a shutter body that closes each wire guide passage of each of the wire guide portions. The present invention is characterized by comprising a plurality of shutter mechanisms that prevent passage of the core wire until the mechanism completes positioning of the core wire positioning insertion section.

[Function] According to such a device, the device uses core wire holders corresponding to the number of terminal rows of the multi-core connector to be connected, and connects these core wire holders to the terminal side of the multi-core cable and to the terminal rows of the multi-core connector. Since each core wire is positioned opposite to each other around the axis of the cable terminal, each core wire can be positioned symmetrically according to each terminal row, and each terminal row of a multi-core connector can be positioned symmetrically. When connecting each core wire to the multi-core cable, the connection can be made so that the center of each terminal row and the center of the multi-core cable almost coincide. When each core wire is inserted into each core wire holder, the display means displays which core wire holder the core wire is inserted into, so that the core wires can be sorted without error. In addition, each core wire holder has a core wire guide section at the top, and each core wire guide section is provided with a shutter mechanism to prevent the core wire from passing through.
Since the shutter mechanism is closed until a specific fiber positioning insertion part of the fiber holder is positioned at the outlet of the fiber guide part, incorrect insertion of the fiber into each fiber positioning insertion part of the fiber holder is prevented. can.

Next, its operation will be explained. The worker picks out one of the many core wires 5 of the multi-core cable 4 to be arranged and brings it into contact with the sensor 9A to establish continuity. Thereby, the wire number of the core wire 5 is identified by the core wire identifier 9. When the wire identification device 9 finishes identifying the wire number, the wire identifier 9 directs the identified wire 5 to the wire guide passage 1 of which wire guide section 11 or 12.
Display means 13 or 1 indicates whether to pass through 1A or 12A.
Send a signal to 4 and display it. The operator passes the core wire 5 across the wire guide passage 11A or 12A which is displayed on the display means 13 or 14. If the positioning of the wire holder 17 or 18 has not yet been completed in this state, the wire guide passage 11A or 12A
or closed at 29. When the fiber identifier 9 finishes identifying the fiber 5, it outputs identification wire number data to the pulse motor 25 of the fiber holder positioning mechanism 20 in addition to the display means 13 or 14. The pulse motor 25 is driven by this identification wire number data, and the core holder 17 on the side corresponding to the identification wire number data is driven.
Alternatively, the wire holders 17 and 18 are moved together with the positioning table 21 so that the wire positioning insertion portion 15 or 16 of 18 corresponds to the outlet of the wire guide passage 11A or 12A, and positioning is performed. When the positioning of the fiber positioning insertion section 15 or 16 is completed, a shutter release signal is output from the fiber identifier 9 to the drive means 30 or 31 of the shutter mechanism 26 or 27, and the drive means 30 or 31 is activated. Then, the shutter main body 28 or 29 is moved backward. As a result, the wire guide passage 11A or 12A through which the core wire 5 is to be passed is opened, so that the operator can
When the core wire 5 is pushed down while applying tension, the core wire 5 escapes from the output of the wire guide passage 11A or 12A and waits at the outlet of the wire guide passage 11A or 12A. 15 or 16. In this way, all the core wires 5
Depending on the wire number, select one of the wire holders 1
7, 18 specific conductor positioning insertion part 15 or 1
6 and perform the arrangement according to the wire number.

After the arrangement of each core wire 5 is completed, the multi-core cable 4
is cut to a required length, the holder substrate 19 is removed from the positioning table 21, and in the next step, for example, each core wire 5, which is in a parallel state with the core wire holders 17 and 18, is fixed with adhesive tape to adjust the arrangement order. Each tape is formed so as not to disturb the spacing, and the two thus obtained tape-formed core wire groups are press-fitted into the pressure contact terminals 2A, 2B of the multi-core connector 1 to connect to the multi-core connector 1.

The core wires 5 on the cut end side of the cut multi-core cable 4 can be arranged in the same manner by connecting the multi-core connector 1 attached in the previous step to the fiber identifier 9.

[Effects of the Invention] As explained above, in the semi-automatic fiber arrangement device for multi-core cables according to the present invention, the core wire holders corresponding to the number of terminal rows to be connected in the multi-core connector are used, and these core wire holders Since each core is positioned by arranging them at the terminal side of the multi-core cable and facing each other around the axis of the terminal of the multi-core cable, each core is positioned symmetrically according to the individual terminal rows. The wires can be positioned, and when each core wire is connected to each terminal row of the multi-core connector, the connection can be made so that the center of each terminal row and the center of the multi-core cable substantially coincide. Further, when each core wire is inserted into each core wire holder, since the display means displays which core wire holder the core wire is inserted into, it is possible to sort the core wires without fail. Furthermore, each core wire holder has a core wire guide section on the upper part, and each core wire guide section is provided with a shutter mechanism to prevent the core wire from passing through. Since the shutter mechanism is closed until the wire is positioned at the outlet of the wire guide section, incorrect insertion of the wire into each wire positioning insertion section of the wire holder can be prevented.
