Each of the core wires 5 is arranged in the insertion part 6 according to its wire number, and then each of the arranged core wires 5 is divided into two core groups 5A, 5B on the left and right from the center, and each of these core wires nY5Δ, 5B is While maintaining the pitch, the bits are fixed by being taped by sandwiching them with adhesive tape from above and below, and the resulting two sets of taped core wires are attached to each terminal row 2 of the multi-core connector 1 in sets. 3 each pressure contact terminal 2A.

The connection work was performed all at once by press-fitting into 3△ 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 There were problems such as the center of the connector 1 did not match, the connection was biased to one side, and it was difficult to insert it into a case.

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 in detail the present invention for achieving the above object, the present invention provides a method for identifying the wire number of an arbitrary core among each core of a multi-core cable. a discriminator; and a plurality of cores installed on the terminal side of the multi-core cable and facing each other around the axis of the terminal of the multi-core cable to guide and pass the identified core wire. Identification wire number data given from the fiber identifier for each fiber holder provided on the exit side of a wire guide portion and a large number of fiber positioning insertion portions corresponding to each fiber guide portion. a fiber boulder positioning mechanism for positioning and moving the fiber positioning insertion portion of the wire number based on the wire number so that it is in a standby position corresponding to the exit of the fiber guide portion; a plurality of shutter mechanisms each having a shutter body that closes each of the fiber guide passages and which prevents the fiber from passing until the fiber holder positioning mechanism finishes positioning the fiber positioning insertion portion; The mechanism is characterized in that it is movably supported by a fixed frame so that it can take a position close to each of the core wire holders and a position spaced apart from the carp.

[f￥: Usage 1 In such a device, the device uses core holders corresponding to the number of terminals 111 of the multi-core connector to be connected,
These core wire holders are placed opposite each other on the terminal side of the multi-core cable and around the axis of the end of the multi-core cable to position each core wire, so that they are symmetrical according to the individual terminal rows. 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 11 and the center of the multi-core cable substantially coincide with each other. In addition, the upper part of each core wire holder has a core wire guide part, and each core wire guide part is provided with a shutter mechanism that prevents the core wire from passing through. X? until the section is positioned at the exit of the wire guide section. Since the twine structure is closed, incorrect insertion of the core wire into each core wire positioning insertion portion of the core wire holder can be prevented. Furthermore, Si1? Since the side of Tsuta R is movable with respect to the fixed frame, by moving the shutter mechanism to a position away from each fiber holder, the shutter mechanism can be moved when each fiber of the multi-core cable is set in the device. The mechanism does not get in the way, and the shutter mechanism does not get in the way when replacing the core wire holder, so work efficiency can be significantly improved.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3. As shown in the figure, in the multi-core cable semi-automatic wire arrangement device of this embodiment, a fixed frame 8 is placed on the right side, and the ends of the multi-core cable 4 in which the helical wires 5 are to be arranged are placed in the fixed frame 8. It is pulled in, and its end is raised and clamped with a clamping tool (not shown). Each core wire 5 contacts the sensor 9Δ of the core wire identifier 9 with a specific core wire 5 to establish continuity, so that the wire number of the core wire 5 can be identified by the core wire identifier 9. There is. In this case, each core wire 5 on the other end side of the multi-core cable 4 is connected to a core wire identifier 9 via a connector 10. A shutter frame 12 is rotatably supported at the upper end of the fixed frame 8 via a pivot support part 11 formed of a hinge. The shutter frame 12 can be held in a horizontal position by a support screw 13 that is threaded upward into the fixed frame 8.

A sensor 9A is supported on the shutter frame 12. A pair of fiber guide passages 14A and 15A are provided in the shutter frame 12 so as to be located on the terminal side of the multi-core cable 4 and facing each other around the axis of the terminal end of the multi-core cable 4. It is provided by guide parts 14.15. Display devices 16.17 consisting of lamps are provided on the upper surface of the shutter frame 12 adjacent to each fiber guide portion 14.15. It is designed to display which side of the fiber guide section 14, 15 into which the fiber core 5 should be inserted at that time according to the data. Each core wire guide section 14
．． On the outlet side of 15, there are a number of core positioning inserts 18.
A core holder 20,21 having a number 19 is arranged in each case.

Both core holders 20, 21 are installed on a common holder substrate 22. The pitch of the core wire positioning insertion portions 18 and 19 is provided to match the pitch of each pressure contact terminal 2A, 3A of the multi-core connector 1.

Based on the identification wire number data given from the fiber identifier 9, each fiber holder 20, 21 has the fiber positioning insertion portion 18 or 19 of that wire number on standby in correspondence with the exit of the fiber guide portion 14 or 15. The core wire holder positioning mechanism 23 positions the wire holder so that the wire holder is positioned as shown in FIG. This core wire holder positioning mechanism 23t has a positioning table 24 on which the holder board 22 is mounted at a predetermined position, a ball screw 26 screwed through a piece 25 under the positioning table 24, and a ball screw 26 in a direction parallel to this. It is comprised of a pair of guides 27 that are passed through the piece 25 and guide the positioning table 24, and a pulse motor 28 as a positioning drive source that rotates the ball screw 26 based on the core identification wire number data.

The shutter frame 12 usually has a double guide part 1.
4.15, the wire guide passages 14A and 15A are closed, and the wire holder positioning mechanism 23 is inserted into the wire positioning insertion section 1.
Mind I until you finish positioning 8 or 19! A pair of shutter mechanisms 29,30 are supported which prevent the passage of 25. These shutter mechanisms 29.30 are rod-shaped shutter bodies 31.30 that slidably pass through both fiber guide portions 14.15 so as to be able to cross each fiber guide passage 14A, 15A or not. 32, and a shutter drive source 33.34 consisting of a cylinder that drives these shutter bodies 31.32.
After the time when positioning of the fiber positioning insertion section 18 or 19 is completed, the timer is activated and the fiber discriminator 9 is activated.

Next, its operation will be explained. To open the work opening, first rotate the shutter mechanism 29, 30 together with the shutter frame 12 clockwise around the pivot 11 in FIG.
With these shutter mechanisms 29 and 30 moved out of the way, the wire holders 20 and 21 are set in the illustrated state, the multi-core cable 4 is set, and each core wire 5 of the multi-core cable 4 is set. Perform work such as starting up from between the core wire holders 20 and 21. Once such preparatory work has been completed, the shutter mechanism 29,30 is rotated back to the position shown. At this time, the horizontal position of the shutter mechanism 29.degree. 30 is maintained at the tip of the support screw 13. Next, work d is
An arbitrary one of the many core wires 5 of the multi-core cable 4 is taken out and brought into contact with the sensor wire 98 to establish continuity. Thereby, the wire number of the heart B5 is identified by the heart VQ identifier 9. When the wire number identification device 9 finishes identifying the wire number, the wire identifier 9 assigns the identified wire 5 to which wire guide section 14 or 1.
A signal is sent to the display device 16 or 17 to display whether the wire is to be passed through the wire guide passage 14A or 15A.

In the work L4, the wire 5 is passed through the wire guide passage 14Δ or 15A which is indicated by the indicator 16 or 17 so as to cross it. In this state, if the positioning of the wire holder 20 or 21 has not yet been completed, the wire guide passage 14A or 15A is closed by the shutter body 31 or 32. When the fiber identifier 9 finishes identifying the fiber 5, it outputs identification wire number data to the pulse motor 28 of the fiber holder positioning mechanism 23 in addition to the display device 16 or 17. The pulse motor 28 is driven by this identification wire number data,
The wire holders 20 and 21 are placed on the positioning table so that the wire positioning insertion portion 18 or 19 of the wire boulder 20 or 21 on the side corresponding to the identified wire number data corresponds to the exit of the wire guide passage 14A or 15A. 24 and positioning is performed. Core wire positioning insertion part 18 or 1
When the time has come for the completion of positioning, the drive means 33 or 34 of the shutter mechanism 29 or 30 is removed from the fiber identifier 9.
A shutter opening signal is outputted to actuate the drive means 33 or 34 to move the shutter body 31 or 32 backward. As a result, the fiber guide passage 14A or 15A through which the fiber 5 should pass is opened, so that when an operator presses down the fiber 5 in the fiber guide passage 14A or 15A while applying tension, the fiber guide passage 14A or 15A is opened. The wire 5 escapes from the output of the wire guide passage 14A or 15A and is inserted into the wire positioning insert 18 or 19 which is located at the outlet of the wire guide passage 14A or 15A. In this way, all the core wires 5 are placed in one of the core wire holders 20.2 according to their wire numbers.
The wires are inserted into one specific wire positioning insertion section 18 or 19 and arranged according to the wire number.

When the arrangement of each fiber 5 is completed, the operator rotates the shutter mechanism 29.30 again in the clockwise direction in FIG. Move, shisetter machine @29.30 is evil 1
I will make sure that it doesn't happen again.

Thereafter, the multi-core cable 4 is cut to a required length, and the holder board 22 is removed from the positioning table 24. Core wire 5
The wire holders 20 and 21 that have been aligned are carried to the next step, where the wire holders 20 and 21 fix each of the parallel wires 5 with adhesive tape to determine the arrangement order and spacing. The two tape-formed fiber groups obtained in this way are connected to the multi-core connector 1.
The connection to the multi-core connector 1 is made by press-fitting it into each of the pressure contact terminals 2A and 2B.

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 wire arrangement device for a multi-core cable according to the present invention, the wire boulders corresponding to the number of terminal rows to be connected in a multi-core connector are used to arrange these core wires. Since the holders are placed opposite to each other on the terminal side of the multi-core cable and at positions around the axis of the terminal of the multi-core cable to position each core wire, each core wire is positioned symmetrically according to each terminal row. The core 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 such that the center of each terminal row and the center of the multi-core cable substantially coincide. In addition, a fiber guide part is placed on the top of each fiber boulder, and each fiber guide part is provided with a shutter mechanism to prevent the fiber from passing through. Since the separate shutter is kept open until the wire is positioned at the exit of the wire guide section, there is an advantage that incorrect insertion of the wire into each wire positioning insertion section of the wire holder can be prevented.

Furthermore, since the sit-tutter b1 structure is movable at λ1 relative to the fixed frame, it is intended to move the sit-tutter mechanism to a position away from each conductor holder. The shutter mechanism does not get in the way when the core wire is set in the device, and the shutter mechanism does not get in the way when the core wire holder is replaced, so that workability can be significantly improved.
