  FIG. 13 is a diagram illustrating a temporary caulking process (third process). Referring to FIG. 13, when the press lever 55 is rotated forward, the temporary crimping mechanism 14 provided on the top plate 26 of the die set 20 of the first jig is lowered. First, the positioning pins 42 a and 42 b are inserted into the positioning bushes 4 a and 4 b of the holder 10. Next, the tip of the punch 31 hits the upper surface of the ground cover 80 and is pushed downward vertically. At this time, the punch 31 can be kept pressed by the spring 34. In this state, the first pressing tools 36a and 36b rotate inward, and the plurality of pressing claws 66 of the ground plate 80 are simultaneously folded back inward to be in a temporary crimping state.

  FIG. 14 is a view showing the main caulking process (fourth process) using the caulking jig. Referring to FIG. 14, the pressing claw 66 that has been crimped in the third step is incomplete as a crimp because it is somewhat opened by the springback. For this reason, it is possible to remove the spring back by adding the main caulking punch 43 which is the second caulking member in the main caulking in this step, thereby forming a stable caulking shape. The holder 10 that has finished the third step is set in the die set (the method is the same as in the second step). Next, when the press lever 55 is rotated forward, the top plate 26 of the second die set 40 is prepared. The caulking mechanism 15 thus moved down.

When the top plate 26 is further pushed downward, the punch 43 having a concave tip portion presses the upper and left and right sides of the claw 66 of the ground base 60 to form a final shape at the bottom dead center.

  When lowered to the bottom dead center, the lever 55 of the press mechanism 50 is released. Then, with the cable holders 45a and 45b holding the cable 70, the punch 43 first rises upward, and the cable holders 45a and 45b also rise upward at a certain stroke. This is because the ground base 60 and the ground cover 80 that form the final shape bite into the recesses of the punch due to the spring back, so that the product is prevented from being lifted while the cable retainers 45a and 45b are held at the lower positions by the springs. This mechanism was added for this purpose.

  15A and 15B are views showing the fifth step (harness removal), where FIG. 15A is an exploded perspective view of the holder 10, FIG. 15B is a sectional view showing a state before the harness is taken out, and FIG. FIG. Referring to FIGS. 15A to 15C, when the caulking is completed, the holder 10 is taken out from the die set 40 of the second jig. Next, the holding plate 6 and the magnet B9 are removed from the holder 10. Thereafter, in order to remove the crimped harness 75, as shown in FIG. 15 (c), when the left lever 3a and the right lever 3b are simultaneously pushed down, the fulcrum B56 and the fulcrum C57 are rotated. Then, the integrated grant base 60 and ground cover 80 are lifted upward. As a result, the ground base 60 fitted to the pins 7a and 7b can be easily removed. When the levers 3a and 3b that have been further pushed down are released, the left lever 3a and the right lever 3b are returned to their original positions by the springs 16a and 16b. With the above, the harness 75 shown in FIG. 10 is obtained, and the work is finished. Referring to FIG. 10 again, each lead wire of the cable 70 is sandwiched between the ground base 60 and the ground cover 80 and connected.

  As described above, according to the embodiment of the present invention, in the process of caulking the ground base 60 and the ground cover 80, which are holding members, to the cable 70 without using solder that causes contact failure, By the operation of the press mechanisms 30 and 50, the punches 31 and 43 hold the ground cover 80 against the cable 70, and in this state, the rotating base a is on the extension of the center of the ground base 60 and the ground cover 80. By rotating the right and left common pressing tool, it is possible to provide a crimping jig and a crimping method that can simultaneously bend the pressing claws 66 of the ground base 60 facing the cable in the length direction.

  In addition, according to the embodiment of the present invention, a cable presser is added as a pressing tool that slides up and down in the cable length direction of the punch in addition to the caulking process for preventing springback and stabilizing the shape. It is possible to provide a caulking jig and a caulking method that prevent biting of the ground base by punching.

  Further, according to the embodiment of the present invention, in order to cope with the narrow pitch of the cable 70, the ground base 60 has a large number of comb-like pressing claws 66, and the surface of the pressing tool that turns back the pressing claws 66 is flat. Thus, it is possible to provide a caulking jig and a caulking method that are lower in cost than a shape like a caulking punch and that can be stably manufactured.
