L1は、端子１の正常なピツチＰの整数倍である。 The above terminal crimping machine is adjacent to the crimping punch 6,
A detection punch 10 is provided so as to be located directly above the stop position of the progressively fed terminals. That is, the detection punch 10 is attached to an operating body 17 that moves up and down integrally with the ram 7 so as to be vertically slidable, and its lower limit position is regulated by appropriate means.
It is elastically biased downward by a coil spring 14 inserted between a vertical hole 10'' bored in the upper half portion and an upper end 17' of the actuating body 17. A detection blade 11 is attached to the detection blade 11, and as shown in FIGS.
It has an eccentricity of a required amount L 2 corresponding to the pitch P of the terminal 1, and is attached to the lower end of the detection punch 10 via a bolt 13 so as to be replaceable. A detection section 12 is formed at the lower end of the detection blade.
2 has a tapered shape that gently fits inside the normal crimp pieces 13A and 13B of the terminal 1 stopped downward when the detection punch 10 is lowered, and the crimping piece 12A that fits into the crimp piece 3A and the crimp piece 2 It is formed by both parts of the slightly wider 12B that fit into the 3B,
The cross section has steps as shown in Figure 5. On the other hand, a detection part 1 provided in a protrusion shape near the upper end of the detection punch 10
5, and the detection unit 15 and the proximity switch 16 attached to the frame 15 constitute a detection mechanism. As shown in FIG. 1, the detection punch 10 is positioned so that the detection blade 11 is on the terminal several terminals behind the terminal 1A located directly below the crimping punch 6, and the vertical axis of the crimping punch 6 and the detection blade 11 is distance between hearts
L 1 is an integer multiple of the normal pitch P of terminal 1.

用が行なわれる。 The terminal crimping machine having the detection punch 10 described above operates as follows. Referring to FIGS. 4, 6, and 7, when the detection punch 10 is at the upper limit position, the Nth terminal 1N from the most advanced terminal 1A of the horizontally chained terminals that are progressively fed is the normal pitch P and the terminal that is progressively fed. As long as it has a pitch, it stops directly below the detection punch 10, and when the detection punch 10 moves downward, the crimping piece 3 of the correct shape
The detection part 12 fits smoothly into the grooves A and 3B, and the detection punch 10 reaches the bottom dead center. Then, the detection unit 15 stops in front of the proximity switch 16, and the normality of the crimp pieces 3A and 3B is confirmed. On the other hand, as shown in FIG.
Since the detection punch 10 stops at an intermediate position against the bias of the coil spring 14, the detection part 15 stops away from the proximity switch 16, and the circuit becomes disconnected, accurately confirming the abnormality and crimping the terminal. The aircraft issues an abnormal signal and stops. The defective terminal 3' is then immediately removed or corrected. Note that the above-mentioned defective terminal detection function is achieved because the crimping pieces 3A, 3B and the detection part 12 come into elastic contact with each other due to the spring bias, and the detection punch 10 retreats into the actuating body 17 in accordance with the contact resistance. There is no need to apply more stress than necessary to the crimp pieces 3A, 3B and damage them. A similar detection operation is carried out for each defective terminal, such composite defective terminals, and progressive pitch defective terminals illustrated in FIGS. 1A to 1E.

置換することができる。 Note that the detection blade 11 may be fixedly attached with its axis aligned with the detection punch 10. However, the detection blade 11 in the above embodiment is replaceable and the eccentricity with respect to the detection punch 10 can be freely changed, so when the shape, size, or pitch P of the horizontal chain terminal is changed, arbitrary detection By replacing the blade with the blade 11, the above-mentioned L1 condition can be satisfied and a smooth detection action can be achieved. The detection mechanism described above may also be replaced by other known means, such as a limit switch.
