Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, crimp terminal pieces provided at a constant pitch on one side of a band-shaped carrier are crimped onto a cable to form a cable with a terminal, and then this is inserted into a terminal insertion hole of a connector housing. The present invention relates to a connector assembly device for attaching the connector.

Conventionally, in this type of device, the device for forming the above-mentioned cable with terminals and the device for inserting the cable with terminals into the connector housing are separate units, and the overall device for assembling the connector has become larger. In addition, there were disadvantages in that a separate operator was required for each device. Furthermore, the supply of connector housings to the insertion device is either carried out manually one by one or automatically by a limited number of connector housings using a magazine, which again has the same drawbacks as mentioned above.

Furthermore, when crimping a crimp terminal piece to each wire of a bundle of shielded wires and multiple covered wires, for example, the thickness of the shielded wires and the covered wires are different, so a single device cannot handle the problem. .

In view of the above-mentioned circumstances, the present invention makes it possible to perform a series of processes such as crimping a cable and inserting a cable with a terminal into a connector housing using one device.
It is also highly efficient and compact, requiring only one worker.
Furthermore, it is an object of the present invention to provide a connector assembly device that can sufficiently cope with the inclusion of wires of different diameters.

The present invention is for crimping terminal pieces provided at a constant pitch on one side of a band-shaped carrier to a cable to form a cable with a terminal, and then inserting the terminal into a terminal insertion hole of a connector housing, which includes the following: As shown in the figure, the pitch feeding section, the crimping section, the insertion section, and the turntable are arranged in sequence in the X direction.

The pitch feeding section intermittently feeds crimp terminal pieces provided at a constant pitch on one side of the strip carrier in the X direction at each pitch by means of a claw or the like that moves intermittently while guiding the strip carrier through a groove or the like. Equipped with a mechanism.

The crimping section is a stop position of one of the groups of crimp terminal pieces that are fed out from the pitch feeding section and are connected to a band-shaped carrier. (lower mold). The punch has a groove on the side opposite to the anvil, and the groove dimensions and height position of the punch, that is, its stroke, are such that the cable from which the tip of the coating has been removed is When placed on a crimp terminal piece, the crimp terminal piece is set to a value suitable for crushing the crimp terminal piece from above and below to surround and tighten and fix the core wire and coated end of the cable. Furthermore, the height position of the punch can be adjusted and switched depending on the thickness of the core wire and the coating.

The insertion section holds a cutting blade that separates the crimp terminal piece (terminal section of the cable) to which the cable is crimped, sent from the crimping section, from the carrier, and the terminal section of the separated cable with the terminal. It also has a holding insertion body that is inserted into the terminal insertion hole of the connector housing from the Y direction.

The turntable has a plurality of radially extending arms for holding the connector housing, and is capable of rotating by a certain angle, reciprocating in the X direction, and moving at a certain pitch. . The above turntable has one arm at the insertion part position (Y of the terminal part of the cable held by the holding insertion part)
After moving in the negative X direction to the front end position of the directional movement, the cable moves one pitch in the X direction each time the cable terminal section is inserted into the connector housing, and returns to the insertion position after all pitches have been inserted. It is set to escape from the center in the X direction. Furthermore, the turntable is then rotated by a certain angle, and then the other arm is placed in the insertion position.

Note that the arm of the turntable is connected to the automatic connector housing supply device when it is in any position other than the insertion position, and is set to receive supply of the connector housing.

It is equipped with

Next, the operation of the device of this embodiment as described above will be explained using a plurality of coated wires 50a, 50b, 50c whose core wires are coated with an insulating material as shown in FIG.
An example of a shielded electric wire 5 having a shield wire 52d that bundles these together and shields the outer periphery will be described.

Covered wires 50a, 50b, 50 having the same dimensions as each other
The tips of the coatings of the core wires 52a, 5c are removed, and the core wires 52a, 5
2b and 52c are exposed. The cylindrical shield wire 52d is formed into a twisted wire 52d' at the tip, and an insulating sleeve 53d is inserted from the tip.
Therefore, the core wires 52a, 52b, 52 of the coated wire
c and the twisted wire 52d' of the shielded wire have different wire diameters, and the covering portions 51a, 51b, 51c of the covered wire
and the shielded wire sleeve 53d have different wire diameters.

In FIG. 1, the strip carrier 1 is
1 until its tip reaches the crimp part 3,
It engages with the pawl 21 of the pitch feeder 2. Next, as shown in FIG. 3, in the crimping section 3, a cable ((in the figure The coated wire 50c) is inserted in the Y direction, and then the adjustment members 35a and 35b are moved to the right direction (X direction) by the cylinders 37a and 37b (that is, the members 35a and 35b are moved to the punch 31).
If the pedal 39 shown in FIG.
1b, the punches are lowered, and the punch 31 and anvil 32 move toward each other, crushing the covering crimping piece 12a and the core wire crimping piece 12b in their crushing grooves 31a' and 31b', Covered wire 5
The covered end 51c of 0c and the core wire 52c are tightened and fixed. Thereafter, the pair of punch 31 and anvil 32 return to their original positions, but at this time, the crimped strip carrier 11 is guided by the groove 41 by the claw 21 of the pitch feeder 2 (see Fig. 3).
It is fed out by one pitch in the direction and prepared for the next crimping. In the figure, the other covered wires 50a and 50b are shown in a state where the terminal pieces have already been crimped by the above method.

Next, a terminal piece is crimped for the shielded wire 53d, but as mentioned above, the diameter of the twisted wire portion 52d' and sleeve 53d of the shielded wire is different from that of the covered wire (generally, in the case of a covered wire, When the crimping of the above number of cables is completed, the adjustment members 35a and 35b are actuated in the negative X direction by the cylinders 37a and 37b, and the punches 31 and 31a engaged therewith are actuated by the cylinders 37a and 37b. The height position of 31b is converted into the value set for crimping the shield wire. Then, the crimping process is performed in exactly the same manner as the crimping for the covered wire described above.

When the terminal crimping for each wire of one shielded wire 5 is completed, the punch 31 moves again to the position set for the covered wire in response to a command from the program board P, and crimps the terminal for each wire of the next shielded wire. Prepare for terminal crimping on wires.

As the crimping process progresses, the cable with a terminal (referring to covered wire and shielded wire), which is formed by crimping the crimp terminal piece 12 provided on the band-shaped carrier 11, reaches the insertion part 7 together with the band-shaped carrier 11. reach One arm 71 of the turntable 7 is located in the insertion portion 7 and receives the connector housing 8 from the feeder 9. arm body 71
The connector housing 8 held in
It is positioned in the X direction. At this point, when the operator depresses the pedal 39 for crimping, the insertion process is also performed at the same time. This insertion process will be explained based on FIG. 4. First, the upper terminal holding piece 63A' of the terminal holding body 63A descends and cooperates with the rear upper surface 63A'' of the cutting blade 62 to connect the cable to the terminal. Part 1
2, and then the terminal portion holder 63A rises to the height of the connector housing 8 while holding the terminal portion 12. At this time, the terminal portion 12 is separated from the carrier 11 at the same time as the rising starts. Next, the arm body 71 of the turntable holding the connector housing 8 moves the terminal part holder 63 in the negative Y direction.
Proceed to the front position A, insert the terminal part 12 of the cable halfway into the terminal insertion hole 81 of the connector housing 8, and then the lower cable holding piece 63B'' of the cable holder 63B rises and the upper cable holding piece 63
Together with B′, hold the vicinity of the cable terminal,
Thereafter, the upper terminal holding piece 63A' of the terminal holding body 63A returns to its original position upward, and the cutting blade 62 returns to its original position downward. Then, the arm body 71 advances in the negative Y direction to the position of the cable holding body 63A. That is, at this point, the terminal portion 12 of the cable is inserted a predetermined distance S into the terminal insertion hole of the connector housing 8, and the insertion process is completed. Then, the arm body 71 moves in the X direction by one pitch d of the terminal insertion hole to prepare for insertion of the next cable with a terminal.

In this way, when the insertion of the cable with terminal into the predetermined number of terminal insertion holes of one connector housing is completed, the arm 71 of the turntable 7 is removed from the insertion position by a distance l in the X direction (that is, the arm 71 is removed from the insertion position by a distance l). 71), when the adjacent arms are rotated counterclockwise by the angle formed by each other, the connector housing, which has completed the insertion process, is located downward, and the arm is removed by the claw 76 of the take-out body 75. taken from. On the other hand, the empty arm body is close to the outlet of the supply pipe 91 of the feeder 9, receives a connector housing from the supply pipe, and is prepared for successive connector assembly.

According to the present invention as described above, the following effects can be achieved.

Since the crimping of the terminal and the assembly of the cable with the terminal into the connector housing are carried out in conjunction with an integrated device, the overall device can be made smaller, and only one worker is required, reducing the cost of work. Contribute to

Since the connector housing can be continuously supplied to the insertion section using the turntable, the same effects as in the previous section can be achieved.

Since the stroke of the pressing die of the crimping part can be changed by a program, even if cables of different diameters, such as shielded wires, coexist, crimping can be performed automatically, improving work efficiency.
