DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection device for an electric connector, and more particularly to a connection device for an electric connector for transferring a core of a multi-core cable one by one and connecting it to a predetermined terminal of the electric connector.

[0002]

2. Description of the Related Art In a system such as a personal computer, a harness in which electric connectors are connected to both ends of a multi-core cable is used to connect a main body and peripheral devices. An apparatus for manufacturing this harness is disclosed in
-272814, JP-A-63-5273 and the like. These devices include a core alignment guide (core alignment means) for aligning the cores at one end of a multi-core cable in a line in a random order, and feed and output cores one by one from the core alignment means. The core includes a rotor (core feeding means) for identifying the number, and a core wire transferring means for transferring the core to a predetermined position of the core holder (or the electrical connector) as a result of the core identification.

[0003]

In the cord aligning means of the above-described apparatus, it is necessary to insert a cord from one end into a cord aligning guide slit having a fixed width. Since the width of the guide slit is set substantially equal to the outer diameter of the sheath of the core wire, the core wire may not be able to be smoothly inserted into the guide slit due to friction between the sheath of the core wire and the substrate. In addition, the covering of the cord is
It is made of a material such as PVC (vinyl chloride), and its hardness changes depending on the temperature of the environment. For this reason, when the core wire is pressed by the core wire pushing plate in a relatively high temperature environment, the coating is compressed in the pressing direction, and the core wire may not be able to be sent out one by one. Further, there is a problem that the method cannot be applied to core wires having different wire diameters.

Further, Japanese Patent Application No. Hei.
No. 330 describes a plate-like member that moves to a terminal position corresponding to a core wire to be pressed, a core wire-contact member that slides on the surface of the plate-like member, and a plate-like member that sandwiches the core wire-press member. And a holding member elastically protruding toward the electrical connector in parallel with the above. This connection device eliminates the need for a comb-shaped member and facilitates positioning of the core wire. However, the device has no problem when the core wire is pressure-connected to the terminal of the upper half of the electrical connector, but when the wire is pressure-connected to the terminal of the lower half, the core is placed on the plate-shaped member. In some cases, poor pressure contact. this is,
This is caused because the position of the terminal is below the line connecting the end of the multi-core cable and the roller.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a connection device for an electric connector having a connection means for securely press-connecting regardless of the position of a terminal to be press-connected.

[0009]

[0010]

In the connection apparatus for an electric connector according to the present invention, the connection means has a core guide member rotatable between a core receiving position and a core guide position. By rotating the guide member, the core wire is reliably guided, and a reliable press-contact connection independent of the terminal position can be realized.

[0011]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a preferred embodiment of a connection device for an electric connector according to the present invention. (Note that a part thereof is omitted for easy understanding.) The electrical connector connection device 2 includes a core aligning means 100 and 100 ′, a core delivery means 200, and a core transfer on a pedestal 10. Means 300, 300 ', connection means
400, 400 'and connector supply means 500.
Of these, the core wire alignment means 100, 100 ', the core wire transfer means 300
, 300 ′ and the connection means 400, 400 ′ are installed symmetrically with respect to substantially the center 0 of the pedestal. (Most parts of the core wire alignment means 100 'and the connection means 400' are omitted.)

The connector 8 is fitted into each connector accommodating groove 520 provided on the turntable 510 of the connector supply means 500, and one of them is pushed up by the cylinder 530 and set in the connector holding portion 540. In addition, 1
When the connection of the connector 8 is completed, the turntable 510
Rotates to push up the next connector.

FIG. 2 is a perspective view showing a state in which the core wire 6 is set in the core wire alignment means 100. Cable clamp 10 with multi-core cable with core wire connected to connector in previous cycle
2 and the air cylinder 114 presses the pressing plate 116
Is retracted, and the movable guide plate 112 and the cable clamp 102 that move integrally with the air cylinder 118 are retracted by the air cylinder 118.

A connector (not shown) is already connected to one end of the multi-core cable 4, and is connected to a core identification unit (not shown) of the connection device 2 via the connector. At the other end of the multi-core cable 4, the sheath 4a is peeled off so that a large number of core wires 6 are exposed for a predetermined length, and the shield wire 4b is folded back. The cable clamp 102 grips the end of the jacket 4a of the multicore cable 4 in this state. The exposed core wires 6 are untwisted with each other by a untwisting jig or the like (not shown).

The movable guide plate 112 is integrated with the plate-like body 128, and guide shafts 130, 130 penetrating the plate-like body 128 are provided.
Along the figure and in the opposite direction. Thus, the interval between the core wire alignment grooves 126 between the fixed guide plate 110 and the movable guide plate 112 can be changed. The fixing lever 120 fixes the interval between the cord alignment grooves 126. The fixing lever 120 is rotated to release the fixation of the gap between the core alignment grooves 126, and the gap is widened to about 2 mm, the cores 6 are aligned, and the frontmost core 6a and the rearmost core 6a are aligned. The guide plate 110 is sandwiched between the guide plates 110 and 112 so that the length of 6z becomes substantially equal, and the fixing lever 120 is rotated in the opposite direction to fix the interval. When the core wire 6 is set in the core wire alignment means 100, the interval between the core wire alignment grooves 126 can be widened, so that the setting of the core wire 6 can be facilitated. still,
When the temperature of the environment or the diameter of the core wire is different from the normal one, the interval between the core wire alignment grooves 126 is adjusted as appropriate. For example, when the ambient temperature is high and the coating of the core wire 6 is soft, or when the diameter of the core wire 6 is small, the interval between the core wire alignment grooves 126 is reduced.

FIG. 3 is a sectional view taken along the line III-III in FIG. The cross section of the left half (root side) 110b of the fixed guide plate 110 has a radius formed on the surface facing the core wire 6 as shown in FIG. Easy to insert into the gap. In addition, a groove is formed on the right half portion (tip side) of the fixed guide plate 110 and the contact surface of the movable guide plate 112 with the core wire 6.
110a and 112a are formed. Therefore, friction with the core wire 6 is reduced.

FIG. 4 shows a core wire aligning means 100, a connector 8,
FIG. 3 is a front view showing a positional relationship of the multicore cable 4. As the air cylinder 118 advances to the right in FIG. 2, the movable guide plate 112 approaches the rotor 208 and the air cylinder 11
4, the pressing plate 116 presses the core wires 6 toward the rotor 208 in a state of being aligned in a line. At this time, the air cylinder
4, the cable clamp 102 also advances, and as shown in FIG.
The position is set so as to face substantially the center of the connector 8 held in 540.

The two guide plates 110 and 112 are located at the front end core wire 6a and the rearmost core wire 6z of the aligned core wires 6, and are located at the ends of the jackets of the multi-core cable 4 and the two guide plates 110 and 112. The connector 8 is inclined at a predetermined angle (θ = 45 ° in the present embodiment) with respect to the longitudinal direction of the connector 8 so that the lengths L ₁ and L ₂ of the core wires between the portions are substantially equal. By this inclination and the end of the jacket of the multi-core cable 4 being directed substantially toward the center of the connector 8, the slack of the entire core 6 is minimized, so that the core 6 is wasted and the jacket of the multi-core cable 4 is reduced. The entanglement of the core wires 6 generated between the end portion and the connector 8 is effectively prevented.

Returning to FIG. 1, the cords 6 aligned in a line are:
The pressing plate 116 driven by the air cylinder 114 presses the core wire 6z at the rearmost end, and is sent to the core wire feeding means 200 one by one.

The core wire feeding means 200 uses a stepping motor 202 as a drive source, and power is transmitted to a rotor 208 via a belt 204 and a shaft 206. Side 210 of rotor 208
Has a tapered shape corresponding to the inclination of both guide plates 110 and 112, and has a concave groove 212 for accommodating the core wire 6. The end of the fixed guide plate 110 faces a part of the side surface 210 of the rotor 208 so that the core wire 6 does not escape outside. The fixed guide plate 110 is provided with a disk-shaped sensor 214 which cuts the sheath of the core wire 6 and comes into contact with the inner conductor. The disc-shaped sensor 214 sends a signal to the core wire identification unit, whereby the left or right core wire transfer unit 300 (30
0 ') grasps the core wire 6 and to which terminal of the connector 8 to connect. When the disk-shaped sensor 214 is made rotatable, the portion where the coating of the core wire 6 is cut is not specified, so that the wear of the disk-shaped sensor 214 can be reduced.

The identified core wire 6 is connected to the core wire transfer means 300 (30
0 ') to the connection means 400 (400'). The chuck 302 of the core wire transfer means 300 is driven by two air cylinders 304 and 306 connected in series, and a movement (transfer) path is determined by a cam groove 310 formed in the box 308. That is, the air cylinders 304 and 306 are
The movable box 314 is driven along. Chuck 302
The connecting rod 316 which slides in the movable box 314 and the cam follower 318 at the end of the connecting rod 316
Is transmitted to the chuck 302. Accordingly, the chuck 302 operates in substantially the same L shape as the cam groove 310. The core wire transfer means 300 includes two air cylinders 304 connected in series.
, 306, it is possible to wait (stop) at a point C intermediate between the points A and B, and the time required to move from the standby position (point C) to the core wire receiving position (point B) can be reduced. If the point C is set closer to the point B by using the shorter air cylinder 304, the time required for the movement can be further reduced. Further, a driving body driven by another driving source such as electricity may be used instead of the air cylinder.

FIG. 5 is a front view showing the connection means 400.
The core wire 6 transferred by the core wire transfer means 300 is placed on the plate member 402 of the connection means 400 while being tensioned by the two rollers 412 and 414 (FIG. 1). The connection means 400 is installed on a table 420 as shown in FIG.

Up and down along with the table 420. As shown in FIG.
The plate-like member 402 is normally set at a position (home position) that faces substantially the center of the connector 8, and returns to the home position after the core wire 6 is pressed into contact with a predetermined terminal of the connector 8. Therefore, the time required for the plate-like member 402 to move to the position of the predetermined terminal and return to the original position (home position) is minimized.

The wing (core guide member) 406 is rotated by a cylinder (not shown) in the box 404 from a position indicated by a solid line (core reception position) to a position indicated by a dotted line (core guide position). A plate-like member 402 and a pair of rollers 412,
A transmission type optical sensor (not shown) is arranged between the wing 414 and the wing 406 when the core wire 6 blocks light.
The core wire 6 placed on the plate-like member 402 is
The plate member 402 is immediately caught between the wing 406 and the wing 406 which is driven to rotate in the direction of arrow D, and the plate member 402 moves to the position of the predetermined terminal of the connector 8 in this state. The core wire 6 aligned with the predetermined terminal is pressed and connected to the terminal by a stuffer (core wire pressure contact member) 408 driven by a driving unit 426, and is cut by a blade 410 attached to the plate-like member 402. You. The extra length of the cut core wire 6 is a pair of rollers 41
Emitted by 2,414. When the crimp connection of one core wire is completed, the wing 406 is moved by the restoring force of the spring 430 to E
The table 420 is moved back to its original position, and the table 420 is moved to return the plate member 402 to the home position. In this connection means 400, the core wire 6 is guided by the plate-like member 402 and the rotatable wing 406, so that the plate-like member 402 is securely connected by pressure contact at any position in the movable range. However, as described above, in order to shorten the moving time of the plate-like member 402, the plate-like member 402 is configured to receive the core wire at the home position.

Returning to FIG. 1, the connector 8 in which the core wires 6 are connected to all the terminals, the cylinder 440 has a connector holding portion 540.
The holding is released by pressing the two side plates. Next, the cable clamp 10 is
2 rotates about the shaft 124 in the direction of arrow F, and moves the connected multi-core cable 4 to a position where the operator can easily take it.

When the work of connecting the multi-core cable 4 attached to the left-hand core alignment means 100 is completed, the right-hand core alignment means is completed.
The 100 '(partially shown) cable clamp and movable guide plate advance, and the next multi-core cable connection operation is started.
Multi-core cable 4 to vacant left core alignment means 100
The setting of the core wire 6 is performed during this connection work. As described above, since the connection work can be performed substantially continuously by the left and right core wire alignment means 100 and 100 ', the operation rate of the connection device is improved.

The preferred embodiment of the electrical connector connection device of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made as needed. For example, instead of urging the wing 406 of the connection means 400 with the spring 430, the wing 406 and the cylinder in the box 404 may be connected directly or via a link. Further, the core wire alignment means 100 of the present invention may be applied to a connection device for crimp connection.
