DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wiring connection for electrical connectors in which a core wire of a multi-core cable is pressed into contact with a terminal corresponding to the core wire of an electrical connector to produce a connection. It is related to the device.

(Prior art) Figure 5A. FIG. 5B is a diagram showing an example of a multi-core cable and an example of a harness in which the multi-core cable is connected to an electrical connector.

In the multi-core cable 1 shown in FIG. 5A, the outer sheath 2 and shield wire 3 at one end are removed to expose a large number of core wires 4 covered by an inner sheath. Further, the electrical connector 6 constituting the harness 5 shown in FIG. 5B is provided with a number of insulation displacement terminals corresponding to the number of core wires 4 of the multi-core cable 1 in its housing at a predetermined distance. Corresponding core wires 4 are press-contacted to the press-contact terminals and electrically connected.

Conventionally, a wiring device for electrical connectors as shown below has been used to press-contact each core wire of a multi-core cable as described above to each corresponding terminal of an electrical connector.

That is, the main wiring device for electrical connectors that has been used in the past is set in the device with a large number of exposed core wires 4 arranged in a row parallel to each other as shown in Fig. 5A. Set the connector in a predetermined position, feed out the set core wires one by one, and insert them one by one between each comb blade of the comb blade-like member having the same pitch as the pitch of the many insulation displacement terminals of the electrical connector. This device inserts the core wires one by one between each comb blade, and then presses the plurality of core wires at once to the pressure contact terminals of the electrical connector.

(Problem to be Solved by the Invention) In the electrical connector wiring device configured as described above, the device feeds out the core wires one by one from the state where the core wires at one end of the multi-core cable are lined up in a row parallel to each other. as,
For example, a device described in Japanese Unexamined Patent Publication No. 62-272814 is known.

This device inserts the core wires into a long and narrow groove that is about the width of a single core wire, lines them up in a row, and pushes the core wires forward one by one by pushing the core wires lined up in a row from behind. It is composed of However, since the core wire is flexible and covered with an inner cover such as vinyl that has some elasticity, in this configuration, it is necessary to adjust the pressing force and amount of extrusion of the core wire from the rear. It was difficult to do this, and sometimes none of the core wires were extruded, or two or more core wires were extruded together.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a wiring device for an electrical connector that is equipped with a mechanism that can reliably take out core wires one by one.

In addition, in the conventional electrical connector wiring device described above, when the core wires taken out one by one are inserted into the comb-like member, the base portion 4a of the core wires is exposed (see Figures 5A and 5B). ), a large number of core wires could become entangled, resulting in a clump of core wires.

Therefore, a second object of the present invention is to provide a wiring device for an electrical connector that is equipped with a mechanism for preventing the occurrence of such clumps of core wire.

Furthermore, in the above-mentioned conventional electrical connector wiring device, it is necessary to insert the core wire one by one between each comb blade, and the relative positioning of the comb blade-like member and the core wire for this insertion is difficult, and it takes a considerable amount of time. It is necessary to provide a positioning means with precision, which increases the complexity of the device, increases costs, and requires time and effort for adjustment. In addition, the comb blade-like member itself has a considerable processing precision, which also increases the cost.

Therefore, a third object of the present invention is to provide a wiring device for an electrical connector that eliminates the use of a comb-like member and is equipped with a mechanism that allows easy positioning of the core wires.

(Means for Solving the Problems) A first electrical connector wiring device of the present invention for achieving the first object described above comprises a plurality of wires arranged in a row parallel to each other on one end side of a multi-core cable. a feeding device that feeds out the core wires one by one, a transfer device that transports the fed core wires to a first predetermined position, and a plurality of core wires that are arranged at a second predetermined position to In a wiring device for an electrical connector comprising a pressure welding device that presses a core wire of an electrical connector having a terminal and a corresponding terminal, the core wire located at the front end of the plurality of core wires to be transferred next to the transfer device is an abutting member that moves between an abutting position where the wires are in contact with each other and a retracted position where the wire is evacuated from the abutment position; a first moving means for advancing the plurality of core wires; a holding means for holding the first moving means at a position where the core wire located at the front end abuts the abutment member; The present invention is characterized by comprising a second moving means for advancing the plurality of core wires by one length of the core wires when the core wires are in the position.

In addition, the second electrical connector wiring device of the present invention for achieving the second objective described above connects a plurality of core wires arranged in a row parallel to each other one by one on one end side of a multi-core cable. An electrical connector having a feeding device for feeding out, a transfer device for transferring the fed core wire to a first predetermined position, and a plurality of terminals disposed in a second predetermined position for the core wire transferred to the first predetermined position. In a wiring device for an electrical connector comprising a pressure welding device that presses the core wire and a corresponding terminal, the core wire is connected to the core wire during the transfer of the fed-out core wire to the first predetermined position or after the transfer and before the pressure contact is performed. The invention is characterized in that it includes a tension applying means for applying tension to.

Further, in order to achieve the above-mentioned third object, a third electrical connector wiring device of the present invention sends out a plurality of core wires arranged in a row parallel to each other one by one on one end side of a multi-core cable. A core of an electrical connector having a feeding device, a transfer device for transporting the fed core wire to a first predetermined position, and a plurality of terminals disposed in a second predetermined position for the core wire transferred to the first predetermined position. In a wiring device for an electrical connector comprising a pressure welding device that presses a wire and a corresponding terminal, the pressure welding device moves to a terminal position corresponding to a core wire to be pressure welded of the electrical connector disposed at the second predetermined position. a plate member that guides the core wire during the pressure welding, a core wire pressure welding member that slides on the surface of the plate member to press the core wire to the terminal, and a wire pressure welding member that sandwiches the core wire pressure welding member. elastically protruding toward the second predetermined position parallel to the plate-like member;
The present invention is characterized by comprising a holding member that holds the core wire between the plate-like member and the plate-like member.

(Function) The first electrical connector wiring device of the present invention advances the plurality of core wires lined up in a row by the first moving means until the front end core wires abut against the abutting member, and The means holds the first moving means at that position, and after the abutting member retreats to the retracted position, the second moving means advances the plurality of core wires arranged in a row by one length of the core wires. This makes it possible to reliably take out only one core wire at the front end.

Further, since the second electrical connector wiring device of the present invention is provided with the tension applying means for applying tension to the fed-out core wire, each core wire is once in a tensioned state before pressure welding, and therefore, after pressure welding, This prevents clumps of core wires from forming in the harness.

Furthermore, the third electrical connector wiring device of the present invention moves the plate-like member to a terminal position corresponding to the core wire to be press-contacted, holds the core wire between the plate-like member and the holding member, and holds the core wire between the plate-like member and the holding member. Since the core wire is pressed against the terminal by the wire pressure welding member, the core wire is pressed against the terminal in an operation corresponding to the operation of inserting the core wire into the comb-like member in the conventional device described above, and therefore The number of steps is reduced by the pressure welding operation in the apparatus, and the comb blade-like member is also unnecessary, which simplifies the apparatus and reduces costs. Furthermore, the core wire can be easily positioned by arranging it along the plate-like member (for example, by placing it on the plate-like member).

(Example) Examples of the present invention will be described below.

FIG. 1 is a perspective view schematically showing an embodiment of the electrical connector wiring device of the present invention.

FIGS. 4A to 4D are diagrams schematically showing the state of the apparatus at each step of its operation.

The electrical connector IO supplied from an electrical connector supply section (not shown) is inserted into the electrical connector transfer box ll from above, carried in the direction of arrow A by the cylinder l2, pushed up by the cylinder l3, and set in the electrical connector holding section l4. I will be. Meanwhile, the next electrical connector is inserted into the temporary holding box l5 and is held by the cylinder l6 so that it does not fall down. By repeating the above cycle, the electrical connectors 1O are sequentially set in the electrical connector holding portion I4. In this electrical connector 10, pressure contact terminals are arranged in two rows at a predetermined pitch.

On the other hand, the multi-core cable 1 is set in the core wire feeding section 20 with the outer sheath and shielded wire on one end side removed and the core wires covered by the inner sheath arranged in a line.

A large number of core wires 4 set in this core wire supply section 20 are fed out one by one by a feeding device 2I, and a transfer device 41
will be handed over to.

Figures 2A and 2B show the core wire supply section 20 and the transfer device 4l.
FIG. 2 is a perspective view showing a schematic configuration. The feeding of the core wire from the core wire supply section 20 will be explained using FIG. 2A, FIG. 2B, and FIGS. 4A and 4D together with FIG. 1.

As the motor 22 rotates, the bobbin 23 rotates, and the cam roller 25 rotates in the direction of arrow B via the endless belt 24. This rotation moves the abutting/feeding member 27 via the rod 26 in the direction of arrow C shown in FIG. 2A, and as shown in FIG. It is now in a state where it has moved to the contact position where it contacts 4a.

In this state, the cylinder 3 constituting the first moving means
8 (FIG. 1) moves forward in the direction of arrow D along the rod 39, advances the second moving means 30 and the push rod 31, and moves the core wires 4 aligned in a row at the front end surface 31a of the push rod 3l. The idle member 32 placed immediately behind is pushed to advance the core wires 4 lined up in a row until the front end core wires 4a abut against the abutting/feeding member 27. In this state, the cylinder 36 constituting the holding means operates to hold the cylinder 38 in that position.

Thereafter, the cam roller 25 further rotates in the direction of arrow B, and moves the abutting/feeding member 27 in the direction of arrow C shown in FIG. 2B to release the contact state between the abutting/feeding member 27 and the core wire 4a at the front end. do.

In this state, the cylinder 33 constituting the second moving means 30 is activated. The cylinder 33 is fixed to a plate-like member 34 having a groove on the top, and a movement amount regulating member 35 to which a rod 33a of the cylinder 33 is fixed is fitted in this groove, and the length of the groove and the movement amount are restricted. The difference from the width of the member 35 corresponds to the diameter of exactly one core wire 4. Therefore, when the cylinder 33 is actuated, the pushing rod 31 moves forward by a length corresponding to the diameter of one core wire 4, and pushes out only one core wire 4a at the front end. In this way, the cylinder 38 brings the core wires 4 lined up in a row into contact with the front end core wires 4a at the contact position.
Advance the cylinder 3 until it comes into contact with the sending member 27.
8 is held in that position, and after moving the abutting/feeding member 27 to the retracted position, the cylinder 33 moves the core wires 4 lined up in a row forward by one length. This reliably prevents the paper from not being fed out or from being fed out at the same time.

Next, with reference to FIG. 2B, the delivery of the front end core wire 4a pushed out as described above to the transfer device 4l will be described.

When the motor 22 rotates further and the cam roller 25 further rotates in the direction of arrow B, the movement of the contact/feeding member 27, which had been moving in the direction of arrow C, is reversed and now moves in the direction of arrow E.
move in the direction. At this time, the front end core wire 4a is pushed out by the front end 27a of the abutting/feeding member 27, and is held between the front end surface 27a and the core wire holding member 28. This core wire holding member 28 is rotatably supported around a pin 29 fixed to the abutting/feeding member 27, and is supported by the arrow F
biased in the direction.

When the abutting/feeding member 27 moves in the direction of arrow E with the core wire 4a being held between the front end 27a of the abutting/feeding member 27 and the wire pressing member 28, the core wire 4a is moved to the transfer device 4.
It is sent in one direction and is clamped by a pair of chucks 42. This chuck 42 is rotatable about a shaft 43, and is biased by a spring 44 in the direction of arrows P and P. The core wire 4a is inserted between the pair of chucks 42 against this spring bias, and the core wire 4a is held between the pair of chucks 42 by the elastic force of the spring 44.

Also, inside the guide groove 37 that guides the core wire 4a, there is a blade (
(not shown), and the core wire 4a is in contact with the blade.
Until it is pushed by the feeding member 27 and inserted between the pair of chucks 42, it comes into electrical contact with the core wire 4a. On the other hand, the other end (not shown) of the multi-core cable is also electrically connected, so that the core wire 4a that has come into contact with the blade, that is, the core wire 4a that will be next pressed into contact with the electrical connector 10 as will be described later, is connected electrically. It is determined which one of the many core wires 4 making up the core cable 1.

Further, a discharge piece 45 for discharging the core wire 4a held by the chucks 42 from the chucks 42 is directed between the pair of chucks 42. This discharge piece 45 is fixed to a discharge piece drive rod 46. The discharge piece drive rod 46 is biased by a spring 47 so that a roller 48 attached to the rear end of the discharge piece drive rod 4B presses against a cam surface 49. When the motor 50 rotates, the discharge piece drive rod 4B is moved by the cam surface 49 against the bias of the spring 47, and the discharge piece 45 is moved by the core wire 4a supported by the chuck 42.
Press to eject it from the chuck 42.

Figure 3 is similar to Figure 2A. Core wire supply section 20 shown in FIG. 2B
FIG. 2 is a schematic perspective view showing a transfer device 4l as well as a press-contact device for press-contacting a core wire to an electrical connector.

As described above, the terminals of the electrical connector IO are arranged in two rows. Although these terminals are not directly shown in FIG. 3, they are represented as two rows of holes 10a, lOb provided in the housing of the electrical connector 10, and each terminal is inserted into each hole 10a, lOb. is provided. When the chuck 42 clamps the core wire 4a, the electrical connector l
Since it is known to which of the many terminals of the electrical connector IO the core wire needs to be crimped, either the right terminal (hole 10a) or the left terminal (hole 10b) of the electrical connector IO can be crimped. ) depending on whether the motor 5
0 rotates forward or reverse from the state shown in FIG. When the motor 50 rotates forward, the chuck 42 causes the two rollers 52a. 52
The core wire 4a is carried between the two rollers (see arrow Q in FIG. 4B), and then the cylinder 51 becomes inactive, and the two rollers 52a and 52b close due to the biasing force of the spring 53, so that the core wire 4a is moved between the two rollers. It is held between 52a and 52b. At this time, the core wire is discharged from the chuck 42 by the core wire discharge piece 45 as described above. The roller 52a is driven to rotate in the H direction via a bobbin 54 and an endless belt 55 driven by a motor (not shown), so that the two rollers 52a. When the rollers 52b clamp the core wire 4a, the rollers 52b also rotate in the summer direction, thereby applying tension to the clamped core wire 4a. In this way, the roller 52a.
52b applies tension to the core wire 4a prior to pressure welding, it is possible to prevent a lump of the core wire from forming at the root portion of the multi-core cable 1 from which the jacket has been removed.

Further, the roller 52a has a groove (not shown) for moving the clamped core wire downward as it rotates in the direction of arrow H.
is provided, and the core wire 4a is applied with tension, moves downward, and is placed on the plate member 6l. On the other hand, a drive device (not shown) for moving the plate member 6l up and down is connected to the plate member 6l, and the core wire 4a is connected to the chuck 42a, the roller 52a, and so on. Until it is carried by the chuck 52b, the core wire 4a held by the chuck 42 is moved up and down to the corresponding terminal position depending on which terminal is to be pressed against it, and is on standby.

Here, the shaft 50a of the motor 50 that moves the chuck 42
is inclined at about 30 degrees from the horizontal so that the tip 42a of the chuck 42 points slightly downward. Therefore, when the motor 50 rotates (forward rotation or reverse rotation), the clamped core wire 4a is pulled to some extent, so that the core wire 4a is moved to the roller 52a. 52b, the core wire 4a is already being pulled to some extent, although not enough to apply tension to the core wire 4a, and therefore, the core wire 4a is already being stretched to some extent, so that the rollers 52a. The time required to apply tension to the core wire 4a at 52b is shortened, thereby shortening the cycle time of the device.

Note that although the case where the motor 50 rotates in the normal direction is explained here, the case where the motor 50 rotates in the reverse direction is exactly the same.
In this case, the core wire 4a is held between rollers 56a and 58b.

When the core wire 421 is held between the rollers 52a and 52b, the motor 50 continues to rotate normally, and the chuck 42 returns to the position shown in FIG. 3 (see arrow J in FIG. 4C). Also, during these rotations, the cam roller 25 further rotates in the direction of arrow B, and the abutting/feeding member 27 moves in the direction of arrow EIIC shown in FIG. 4C, and is placed at the abutting position shown in FIG. 2A. . Thereafter, in the same manner, as shown in FIG.
7 moves in the direction of arrow E, the core wire 4b is clamped by the chuck 42, and at this time, the terminal corresponding to the core wire 4b is also determined.

On the other hand, the core wire 4a placed on the plate member 6l is pressed into contact with the corresponding terminal of the electrical connector IO in the following manner.

This pressure welding device 60 is equipped with a wire pressure welding member B2 that slides on the plate member 61, and is further placed on the wire pressure welding member 62 and is pressed against the wire pressure welding member 62 by a spring 63. A holding member 64 is provided which is biased so as to protrude toward the electrical connector 10. motor 65
When the rod 66 rotates, the rod 66 moves in the direction of the arrow K, and with the core wire 4a sandwiched between the plate-like member 6l and the holding member 64, the core wire 4a is moved to the corresponding position of the electrical connector 10 by the wire pressure welding member G2. While being press-contacted to the terminal, the front end portion of the core wire 4a protruding from the terminal is cut off. At the moment of this pressure contact, a motor (not shown) stops so as not to apply unreasonable tension to the core wire 4a, thereby stopping the rotation of the rollers 52a and 52b. The purpose of applying tension to the core wire 4a is to prevent a lump of the core wire from forming at the root portion of the multi-core cable 1 from which the outer sheath has been removed, and it is not necessary to apply tension until the time of pressure welding. That's because there isn't. When the motor 65 further rotates after the pressure contact, the rod 6B moves down in the direction indicated by the arrow.

Also at this time, two rollers 52a. 52b rotates,
The cut front end portion of the core wire 4a is conveyed in the direction of arrow M shown in FIG. 4D and discharged from the apparatus.

The pressure welding device 60 shown in FIG. 3 is for pressure welding the terminals arranged on the right side of the electrical connector 10, and the electrical connector wiring device in this embodiment includes the electrical connector l.
Another pressure-welding device is provided for pressure-welding the terminals lined up on the left side of O, but the pressure-welding device 60 shown in FIG.
The structure and operation thereof are substantially the same, and illustration and description thereof will be omitted here.

Since the core wire 4a to be pressure-welded in this way is placed on the plate-like member ol, the core wire can be easily positioned.
In addition, the core wire 4a is pressed into contact with the electrical connector 10 in a process corresponding to the step of inserting the core wire into the comb-like member used in the conventional device, which simplifies the device and shortens the operation cycle. The goal is to

(Effects of the Invention) As explained in detail above, the first electrical connector wiring device of the present invention has a contact position where the front end of the plurality of core wires arranged in the feeding device abuts. Since the feeding device is equipped with the above-mentioned first moving means, holding means, and second moving means, the core wires are moved one by one. It will definitely be sent out.

Further, the second electrical connector connection device of the present invention includes a tension applying means for applying tension to the fed-out core wire while the core wire is being transferred to the predetermined position or after the transfer and before the pressure welding is performed. This prevents the formation of clumps of core wires.

Furthermore, in the third electrical connector wiring device of the present invention, the pressure welding device includes a plate-like member that moves to a terminal position corresponding to the core wire to be pressure-welded, and a wire pressure-welding member that slides on the surface of the plate-like member. and a holding member that pinches the core wire pressure welding member and elastically protrudes toward the electrical connector in parallel with the plate-like member, so there is no need to provide a comb-like member as in conventional devices. In addition, the core wire can be easily positioned, and the cycle time of the device can be shortened.
