2. Description of the Related Art In recent years, multi-core cables having connectors at both ends have been used for connection between electronic devices, for example, connection between a personal computer and a printer. As this connector, a press-contact type connector that can be connected simply by pushing the core wire into the U-contact is used, but as the number of core wires increases, many U-contacts are arranged on both sides of the connector body. Double-sided connectors have been used.

In order to connect the core wire of a multi-core cable to such a double-sided connector, a skewer-shaped holding groove for holding the core wire at a predetermined interval and a press-contact blade for pressing the core wire to the U-contact of the connector are provided. The core wires are mounted in a predetermined arrangement on a holding jig, the jig is pressed against the surface of the double-sided connector having the U contacts, and the individual core wires are pressed into the corresponding U contacts. After attaching the core wire to a protector (insulating cover) having a skewer-shaped holding groove in a predetermined arrangement, the protector is attached to the U-side connector
There is also employed a method in which connection of individual core wires and mounting of the protector are simultaneously performed by pressing the core against a surface having contacts.

In any case, before connecting the core wire to the double-sided connector, it is necessary to hold the pressing jig on the wiring surface of the pressure welding jig at a predetermined interval and arrangement. As such a wiring device, a mechanism for holding and moving the pressure welding jig is provided inside the device frame, a guide groove for dropping the core wire to a predetermined position is provided on the upper surface of the device frame, and the pressure welding jig is moved by moving the above pressure welding jig. A structure is adopted in which a predetermined position of the wiring surface is positioned so as to be located below the guide groove, and in this state, the core wire is pushed down through the guide groove, thereby holding the core wire at a predetermined position of the pressure welding jig. Have been.

In this case, the core wire at one end of the multi-core cable is randomly connected to a connector in advance, and this connector is connected to a position detecting device for the core wire to wire the core wire at the other end. . In other words, the core wires at the other end are picked up one by one by hand, and a weak current is passed through the human body between the core and the position detecting device, and the position of the core wire to be arranged on the wiring surface of the pressure welding jig is detected. I do. Based on this signal,
By moving the pressure welding jig, a predetermined position on the wiring surface is accurately positioned below the guide groove. In this state, by pushing the core wire downward through the guide groove, the wire is formed at the place where the core wire is to be arranged on the wiring surface of the pressure welding jig.

[0006] On the other hand, the applicant of the present invention arranges the core wires of the multi-core cable in a line, sandwiches them by a pair of guide plates, and slides a pusher having a push blade inserted between the guide plates along the guide plates. As a result, the core wires are extruded one by one from the end of the guide plate, and the core wire extruded from the end of the guide plate is changed in direction by another pusher and extruded. At this time, the energizing blade arranged on the side of the pusher We have already proposed a wiring device that cuts the insulation coating of the core wire and conducts electricity to detect the position of the core wire pressing jig to be arranged on the wiring surface, and a core wire supply guide jig used for it. (See Japanese Patent Application Nos. 2-182375 and 2-73266).

[0007]

In the conventional core wire supplying method, the core wires of the multi-core cable are formed in a bundle in which the core wires are randomly arranged. It had to be done manually and automation was difficult.

Further, in the core wire supply guide jig which has been already proposed by the present applicant, the core wires of the multi-core cable are arranged in a line and sandwiched by a pair of guide plates, and this guide plate is to be mounted on a core wire supply device. When doing so, the core wire spilled from the end of the guide plate, and the work of aligning the core wire had to be performed again.

Therefore, an object of the present invention is to provide a core wire supply guide jig in which the core wires of a multi-core cable are arranged in a line, sandwiched between a pair of guide plates, and pushed with a pusher to push the core wires one by one from the end of the guide plate. An object of the present invention is to provide a tool that prevents a core wire from spilling from an end of the guide plate while the core wire is mounted on a core wire supply device with the core wire held between the guide plates.

[0010]

In order to achieve the above object, the present invention provides a core wire supply guide jig for supplying core wires of a multi-core cable one by one, one end of which can be freely opened and closed so as to clamp the core wire. A pair of guide plates, and a pusher having a push blade inserted between the guide plates in a state where the guide plates are closed and abutting against a side portion along a longitudinal direction of the guide plates. On one side, a through-hole opening on both side surfaces of the guide plate is formed, and in this through-hole, a lever pivotally supported at the center is mounted. A push pin whose head protrudes and retracts from the outer surface by movement is mounted, and a stop pin whose head protrudes and retracts from the inner surface by rotation of the lever is mounted on the other end of the lever.

1 to 3 show an embodiment of a core wire supply guide jig according to the present invention.

As shown in FIGS. 2 and 3, the core wire supply guide jig 31 has a pair of guide plates 32 made of a comparatively long plate material, and these guide plates 32 have one ends thereof. Are openably and closably connected by a hinge mechanism. On one side of the guide 32, a step portion 32a is formed in which an outer corner is cut out in an L-shape.

The core wire supply guide jig 31 has a pusher 35 assembled to the guide plate 32.
The first pusher 35 includes a prism-shaped block 36 and a pair of holding plates 37 attached to both sides of the block 36.
And a push blade 38 protruding from the center of the block 36 in a rib shape, and a dovetail groove 39 formed at one end of the block 36. In this case, the thickness of the push blade 38 is made substantially the same as the diameter of the core wire of the multi-core cable.

In the present invention, a means is provided at one end of the guide plate 32 for preventing the core wire from moving when the core wire is pinched.

That is, as shown in FIG. 1, a through hole 12 is formed at one end of one of the guide plates 32a and opens on both side surfaces of the guide plate 32a. The opening 12a on the outer surface of the through hole 12 has a large slit shape, and the opening 12b on the inner surface has a relatively small oval shape.

A shaft hole 13a is formed in the center of the through hole 12, and a lever 13 having a pair of ends 13b and 13c extending in parallel in opposite directions from the center is inserted. The lever 13 is rotatably supported in the through hole 12 by a support shaft 14 inserted through a shaft hole 13a at the center.

At one end 13b of the lever 13, there is formed a hole 13d penetrating in a direction perpendicular to the support shaft 14,
The push pin 15 is press-fitted into the hole 13d. The head of the push pin 15 has a rounded shape, and the lever 1
By the rotation of 3, the shaft 3 protrudes from the opening 12a outside the through hole 12. Further, the leg of the push pin 15 passes through the hole 13d and comes out on the opposite side.

A hole 13e is formed at the other end 13c of the lever 13 in a direction perpendicular to the support shaft 14.
The retaining pin 16 is press-fitted into the hole 13e. The head of the retaining pin 16 is moved by the rotation of the lever 13 so that
It protrudes and emerges from the opening 12b inside 2.

A spring 17 having one end in contact with the end 13d of the lever 13 and the other end in contact with the inner wall of the through hole 12 is mounted on the outer periphery of the leg of the push pin 15. The lever 13 is biased in a direction in which the push pin 15 and the stop pin 16 protrude outward.

Therefore, when the core wires 3 of the multi-core cable are arranged in parallel one by one and sandwiched between the pair of guide plates 32a, 32b, the head of the stop pin 16 becomes the other guide plate 32b.
Of the guide plate 32a, 32b can be prevented from spilling from the ends of the guide plates 32a, 32b. When the guide jig 31 is inserted into a receiving groove of a core wire feeding device, which will be described later, the head of the push pin 15 comes into contact with the inner wall of the receiving groove and is pushed. It is drawn into the through hole 12. For this reason, when the pusher 35 is slid in the state shown in FIG. 3, the core wire 3 sandwiched between the guide plates 32a and 32b is pushed by the push blade 38, and is pushed out one by one from the ends of the guide plates 32a and 32b. It will be.

FIG. 4 shows an example of a core wire aligning device for aligning the core wires in a line and holding the core wires with the guide jig 31.

This core wire aligning device has a substrate 41, on which a concave groove 42 for receiving one guide plate 32 of the core wire supply guide jig 31 is formed. The concave groove 42 is formed at substantially the same depth as the thickness of the one guide plate 32, and when the one guide plate 32 is placed in the concave groove 42 with the guide plate 32 facing downward, the guide plate 32 disposed below the upper surface of the substrate 41. Is flush with the upper surface.

A support table 43 is provided on the substrate 41, and an elevating block 45 is mounted so as to be able to move up and down via a pair of guide shafts 44 erected on the support table 43. A holding member 46 is attached to the lifting block 45, and a lower edge portion of the holding member 46 can be brought into contact with the upper guide plate 32 when the guide plate 32 is closed. The lifting block 45 is constantly urged upward by a spring (not shown).

A cam member 47 is slidably inserted into the support table 43 adjacent to the elevating block 45 as shown by an arrow A in the figure. Knob 48 is fixed. On the lower surface of the cam member 47, a cam surface 49 having a fitting concave portion at the right end is formed, with the left side being deep and the right side being shallow in the figure. In connection with this, a shaft (not shown) extending below the cam member 47 protrudes from the elevating block 45, and a roller mounted on the shaft contacts the cam surface 49.

Therefore, when the cam member 47 is slid as shown by the arrow A in the figure, the lifting block 45 and the pressing member 46 perform the lifting operation via the roller which comes into contact with the cam surface 49. In this case, by pushing the cam member 47 leftward in the figure, the lifting block 45 and the pressing member 4 are pressed.
6 descends, and the guide plate 32 is pressed on the lower surface of the pressing member 46. When the gap between the pair of guide plates 32 has a length corresponding to the diameter of one core wire 3, the roller connected to the lifting block 45 is fitted into the fitting recess of the cam surface 49, and The block 45 and the holding member 46 are locked.

And a main body 55.

Therefore, when using this core wire aligning apparatus, first, the core wire 3 of the multi-core cable 1 is placed on the substrate 41, and the core wire 3 is flattened using the rollers 51 to be flattened. When the core wires 3 are arranged one by one in this manner, the core wires 3 are sandwiched between a pair of guide plates 32. In this state, when the knob 48 is pressed and the cam member 47 is slid to the left in the drawing, the lifting block 45 and the pressing member 46 are lowered via rollers (not shown) abutting on the cam surface 49, and the lower surface of the pressing member 46 The upper guide plate 32 is pressed against the lower guide plate 32. When the core wires 3 are arranged one by one between the guide plates 32, when the gap between the guide plates 32 becomes the same as the diameter of one core wire 3, The upper and lower positions of the lifting block 45 and the pressing member 46 are locked by the engagement of the rollers. When the cam member 47 can be pushed only halfway in the left direction in the figure and the lifting block 45 and the pressing member 46 cannot be locked, it means that the core wires 3 are overlapped.
The guide plate 32 is opened again, the core wire 3 is taken out, and the above operation is repeated.

In this way, the pushers 35 are mounted on the guide plate 32 as shown in FIG. 3 and the guide plate 32 is kept closed in a state where the core wires 3 are arranged one by one and sandwiched between the guide plates 32. Then, the guide plate 32 is extracted from the concave groove 42 of the substrate 41 and is carried to a wiring device for the core wire 3 described later. At this time, as described above, the core wire 3 is fixed to the guide plate 3 by the stop pin 16 provided on one guide plate 32.
2 is prevented from spilling from the end.
