FIG. On the upper surface 10a of the base 10, two ridge-shaped anvil adjustment guides 10b and 10b 'are provided so that the placed anvil holder spacer 14 can slide on the base 10.

On the anvil holder spacer 14, an anvil holder 15 having a caulking anvil 11 and a shear blade 12 and an outer shear blade 13 adjacent to the caulking anvil 11 are provided.

As shown in FIG. 2, the shear blade 12 is provided so as to be movable up and down with respect to the outer shear blade 13, and is provided on the lower surface 12a of the shear blade 12.
And a terminal holding plate 16 toward or away from the interior. 17 is
The terminal holding plate 16 is elastically moved to the lower surface 1 of the shear blade 12.
Reference numeral 18 denotes a support spring for pressing the shear blade 2a, and reference numeral 18 denotes a holding spring for elastically supporting the shear blade 12.

Next, a method of crimping the terminal by the above-described crimping anvil 11 and shear blade 12 will be described. A caulking anvil 11 as shown in FIG.
The terminal 10 is crimped by placing the base 10 on which the terminal carrier 3 is arranged under the crimping head 8 of the terminal crimping machine 1 as shown in FIG. 9 and feeding the terminal carrier 3 toward the shear blade 12. I have to. At this time, the base 10
Although it may be fixed to the terminal crimping machine 1, it may be fixed so that the base 10 itself can be easily replaced.

First, as shown in FIG.
By pushing down the drive pin 19 provided on the
The holding plate 16 is separated from the lower surface 12a of the shear blade 12.
To advance, feeding a terminal carrier 3 of the terminal carrier 3
See write sent to Shiyaburedo 1 2 through the clearance 13a of the A <br/> c Tashiya over blade 13 adjacent to the Shiyaburedo 12 in the front side direction, between the lower surface 12a of the terminal holding plate 16 and Shiyaburedo 12, Terminal carrier 3
Is introduced. At this time, the shear blade 12
It is in the highest position.

After the terminal carrier 3 is introduced into a predetermined position, as shown in FIG. 4, when the drive pin 19 is raised in the direction of the arrow, the terminal carrier 3 is brought into contact with the terminal holding plate 16 and the lower surface 12a of the shear blade 12. Sandwiched between. Then, as shown in FIG. 5, the shear blade 12 is lowered with the terminal carrier 3 held therebetween, and when the lower surface 12a of the shear blade 12 falls below the clearance 13a of the outer shear blade 13, the shear blade 12
Due to the shearing action between the terminal carrier 3 and the outer shear blade 13, the end 3b of the pinched terminal carrier 3 is cut and separated.

Next, as shown in FIG. 6, the conductor 20 is placed on the conductor connecting portion 2a of the terminal 2 connected to the terminal carrier 3 held therebetween, and the caulking anvil 11 and the caulking head 8 are mounted.
Then, the terminal 2 and the conductor 20 are crimped by crimping.

At this time, as shown in FIG. 7, the terminal carrier 3 is connected between the lower surface 12a of the shear blade 12 and the terminal holding plate 16 as shown by a broken line in FIG. Since the carrier 3 is sandwiched in a wide range by the joint P 'with the terminal 2, the carrier 3 is held in an extremely stable state.

After the terminal 2 and the conductor 20 are crimped, the shear blade 12 is further lowered, so that a shearing action between the caulking anvil 11 and the shear blade 12 causes a connection between the terminal carrier 3 and the terminal 2. Cut 3c,
The terminal 2 to which the conductor 20 is crimped is separated from the terminal carrier 3.

FIG. 8 is a configuration diagram showing the arrangement of devices when crimping is performed on six different types of terminals. A terminal carrier in which six bases A, B, C, D, E, and F are arranged on a rotatable circular base 21 and six types of terminals are connected to each other in a chain at a distance from the circular base 21. A ', B',
C ', D', E ', F' are wound side by side in a roll. Each of the bases A to F is configured in the same manner as the base 10 described above, and includes a caulking anvil, a shear blade, a terminal holding plate, an outer shear blade, and the like (not shown). Types of terminal carriers A '
To F ′.

Next, the step of crimping the terminal carriers A 'to F' will be described. For example, when crimping is performed on the terminal carrier A ′, the circular base 21 is rotated to align the base A on the moving line 22, and the base A is separated from the circular base 21 to move the moving base 22.
Along the terminal carrier A 'to a position S in front of the terminal carrier A'. On the other hand, although not shown, the crimping head is also positioned directly above the base A and the terminal carrier A 'is fed into the base A, so that the crimping is performed by the same operation as in the above-described embodiment.

When crimping of the terminal carrier C 'is completed after the crimping of the terminals of the predetermined number of terminal carriers A' is completed, the base A is returned to the original position of the circular base 21 and then the base C is Along the moving line 22 with the terminal carrier C '.
Of the terminal carrier C 'and crimped to the terminal of the terminal carrier C' by the same operation as that of the terminal carrier A '.

By repeating such operations to match the desired terminal carriers A 'to F' with the corresponding substrates A to F, the respective terminal carriers A 'to F'
Can be arbitrarily selected to quickly and accurately perform crimping. The number of terminal carriers A 'to F' is not limited to six, and each terminal carrier is not limited to a different type and may be of the same type.

[0023]

According to the present invention, the terminal carrier is sandwiched between the shear blade and the terminal holding plate .
Since the terminal carrier is separated from the chain and the conductor and the terminal are crimped in the sandwiched state, the conductor connection portion of the terminal is secured on the caulking anvil in a stable state, and the crimping position Can be held accurately, so that the crimping accuracy is improved, and highly reliable crimping is possible. Further, since the caulking anvil, the ascending / descending shear blade and the outer shear blade are provided on a movable base, by disposing a plurality of bases corresponding to a plurality of types of terminals, a desired terminal carrier and a desired terminal carrier can be provided. The terminal and the conductor can be crimped on the caulking anvil provided on the substrate by arbitrarily selecting a matching substrate, so that crimping can be performed efficiently on different types of terminals, and There are advantages such as being suitable for variety production.
