Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multicore cable wiring method and apparatus for wiring core wires to connectors, connector covers, etc.

[Prior art J] Generally, a multicore cable with a circular cross section called an I10 cable is used for signal transmission between office automation equipment.
A flat connector is used to connect the end of this multicore cable to OA equipment or the like. When connecting the terminal of the I10 cable to the flat connector, each core wire of the multicore cable is identified by the color and display of the core wire insulator, and the wires are connected in a predetermined order.

However, with the miniaturization of connectors in recent years, the spacing between core wire connections has become narrower and the core wire diameter has become thinner, making it difficult for workers to recognize the wire numbers and route the core wires in designated positions using color display identification. It became difficult. Particularly in the case of double-row wiring in different directions, it is difficult to recognize the state of the core wires near the exposed core wires at the terminals of multi-core cables, and together with the tendency for core wires to become tangled, this can lead to quality problems and There were problems with work efficiency, such as difficulty in routing the core wires. In addition, when wiring the core wire to the connector cover, the width of the core wire insertion groove in the cover is narrow, so the wire must be wired sequentially from the back of the groove, which takes time to identify the incense sticks and wires, reducing work efficiency. was bad.

[Problems to be Solved by the Invention] It is an object of the present invention to provide a multi-core cable wiring method and device that solves the above-described conventional problems and also facilitates automation of the wiring work.

[Means for Solving the Problems] That is, in the multi-core cable wiring method according to the present invention, after all the core wires are wired in a core wire fixing jig, the core wire fixing jig is moved and a connector or a connector cover is installed. It is characterized by wiring to etc.

Further, the multi-core cable wiring device according to the present invention includes inner and outer core wire fixing jigs, a first rotation fulcrum that rotates to open and close the inner core wire fixing jig, and a first rotation fulcrum that rotates and opens and closes the outer core wire fixing jig. It is characterized by a configuration including a second rotation fulcrum.

[Operation] Therefore, according to the above configuration of the present invention, while checking the exposed vicinity of the core wire at the terminal of the multi-core cable, the wire number of the randomly picked core wire can be confirmed by color display or electrical identification, and the wire number can be directly checked. Wire the core wire in advance on the core wire fixing jig without wiring it to the connector, connector cover, etc. After wiring all the core wires, open and close the core wire fixing jig to wire the connectors, connector covers, etc. all at once.

[Example 1 The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a partially simplified diagram illustrating the present invention in detail, in which the core wire 2 taken out from the multicore cable 1 is attached to a core wire fixing jig 3.
．． 4.5.6, the wire numbers are identified by an electrical continuity test, and then the connector cover 7 is inserted into a predetermined position and the wires are wired.

FIGS. 2 to 6 are diagrams showing main parts of the multicore cable wiring apparatus according to the present invention and for explaining the wiring operation.

7 to 14 show embodiments of a multicore cable wiring apparatus according to the present invention.

Moreover, FIG. 15 shows a conventional example, in which the core wire 2 is attached to the inner connector, which has a first cover 7A and a second cover 7B.
The cover 7B has a fitting hole 8 formed therein, and the first cover 7A
A slit 9 into which a multi-core cable is inserted, a boss 10 for fitting, and a groove 11 for receiving a core wire of the multi-core cable are formed.

The multicore cable wiring device according to the present invention has a pair of inner core wire fixing jigs 3.4 as shown in FIGS. 1, 2, 7, etc.
and a pair of outer core wire fixing jigs 5.6, the inner core wire fixing jig 3.4 is rotatable by the opening/closing fulcrum 12, and the outer core wire fixing jig 5.6 is rotatable by the opening/closing fulcrums 13A, 13B. It is. As shown in FIG. 8, by expanding and contracting the rod 14.15 having a cylinder portion and moving the rod 14.15 up and down via a link mechanism, these core wire fixing jigs can be moved to opening/closing fulcrums 12.13A and 13B. It opens and closes mainly on the . Then, when the rod 14.15 is raised as shown by the dotted line from the state where the core wire fixing jig is a solid line, the outer core wire fixing jig 5.6 is moved to the inner core wire fixing jig 3 (not shown).
．． The outer core wire fixing jig 5.6 is provided with a stopper mechanism to prevent its core wire holding surface from rotating in advance relative to the outer core wire fixing jig 5.6. FIG. 2 is a plan view showing a state in which the core wire is wired on the core wire fixing jig, and FIG. 6 is a front view thereof. The multi-core cable 1 is fixed by a clamp 16 as shown in FIG. 12, and the core wires are distributed to the left and right sides, and the inner and outer core wire fixing jigs 3.4.5.6 are used as shown in FIGS. 9 and 10. held in the groove.

After all the core wires of the multi-core cable 1 have been wired, the core wire fixing jig is closed around the opening/closing fulcrum 12 as shown in FIG.
In this state, as shown in FIGS. 4, 11 and 12, the first cover 7 of the connector is inserted between the inner core wire fixing jig 3.4 and the outer core wire fixing jig 5.6. 1st cover 7
After supplying, the inner core wire fixing jig 3.4 is fixed so as not to operate. Then, as shown in FIGS. 5, 13, and 14, the rod is shrunk and the outer core wire fixing jig 5.6 is
Opens around opening/closing fulcrums 13A and 13B.

Finally, the second cover 7B of the connector is placed on the connector, the excess core wire protruding from the second cover 7B is cut off, and the blade-like terminals of the connector are press-connected to complete the press-connection of the multi-core cable of the connector. As described above, the wiring number is recognized not by visual inspection but by electrical continuity testing. ” [Effects of the Invention] As is clear from the above description, according to the configuration of the present invention, after all the core wires are wired to the core wire fixing jig, the core wire fixing jig is moved and attached to the connector, connector cover, etc. This eliminates the need to route the core wires of a multi-core cable in ascending order of wiring number, allowing you to route multi-core cables taken out arbitrarily, making it possible to perform high-quality wiring at low cost, and to make wiring easier. By performing number recognition by electrical continuity testing rather than visual inspection, wiring errors can be eliminated and wiring can be automated.
