It's meant to be held. In addition, in the figure, 50 is a guide member.

Next, the operation of this embodiment will be explained. After setting the parallel covered lead wire 1 at a predetermined position on the punching die portion 10 in the illustrated standby state in which the tapping rod 27 is located above the punching body 12,
When the tapping rod 27 is lowered, each punch 17
The connecting portion 3 of the parallel coated lead wire 1 that has entered is drilled over a predetermined length to form a long hole 8, and the drilling operation is completed.

Next, when the grip portion 46a of the actuating rod 46 is grasped and pulled, the cam rod 48 and the roller 40 are removed.
The roller 40 is guided by the slope 48a of the cam rod 48 and moves to the right in FIGS. 4 and 5. As a result, the slide body 38 also moves in the same direction while resisting the biasing force of the spring 37, and the link 34 also moves in the same direction. Therefore, the lower surface of the container 41 is opened and the connector 4
On the other hand, as the link 34 moves, the arm 32 rotates in the counterclockwise direction of rotation of the hour hand in the upper part of FIG. moves from above the perforated body 12 onto the pressing body 19. At this time, if the connectors 4 that had already fallen in the same manner are located below the cover 42 and one of them is in contact with the guide member 50, then the connectors 4 will be pushed and moved at the same time as the movement of the actuating rod 46 described above. Rod 49 also moves in the same direction,
The connector 4 is pushed along the guide member 50 and moved to a predetermined position in the connector receiving portion 9c. At this predetermined position, the connector 4
is in a state where it is held between the tip of the pushing rod 49 and a pair of recessed surfaces formed on the wall surface of the machine base 9. Here, the parallel coated lead wire 1 in which the elongated hole 8 has already been formed is fed in its longitudinal direction and set in a predetermined position of the connector 4, and then the tapping rod 27 is lowered, so that it is pressed by the pressure welding punch 23. Each elongated hole 8 of the parallel covered lead wire 1 enters into the insertion portion 5a of the housing 5 of the connector 4, and the coating film is further destroyed by the pressure contact portions 6a, 6b of the conductor 6, and the conductor 6 The press-contact parts 6a, 6b and the conductive wire 2 in the parallel covered lead wire 1 come into contact, and the joining operation is completed.

Next, when the actuating rod 46 is plunged into the machine base 9,
The cam rod 48 and the pushing rod 49 also move in the same direction, and the engagement between the roller 40 and the cam rod 48 is released, and the slide body 38 is moved to the standby position by the biasing force of the spring 37. to return to. As a result, the connector 4 that had fallen from the container 41 is pushed downward to the cover member 42 by the pushing part 38a of the slide body 38, and the open lower surface of the container 41 is closed again and stored. The connector 4 housed within the body 41 is prevented from falling. Due to the pushing operation of the pushing part 38a as described above, the connector 4 below the cover member 42, which was located at the most extreme end on the side opposite to the container, comes into contact with the guide member 50. On the other hand, the link 34 moves in the same direction as the slide body 38 returns, and thereby the arm 32 rotates about the shaft 31 in the direction of rotation of the hour hand in the upper part of FIG. By rotating in the same direction, the tapping rod 27 is positioned above the perforating body 12 again, and one cycle of work is completed.

Note that if the size and position of the cutout portion 26a in the regulation plate 26 are changed, each press punch 23, 2
3. It is possible to change the operation of the press punches 23, 23, . can.

In this way, according to the present invention, the position of the tapping rod is changed by simple manual operation of the operating rod, and thereby the drilling work and the pressing work are performed alternately, so that the drilling position can be changed. Even if the lead wires are not provided at regular intervals and vary in a complicated manner, it is possible to reliably perform both of the above operations and connect the long parallel covered lead wires and the connector at the desired position, and also The work can be done at a pace appropriate to the skill of the operator, making it extremely safe, and it also has many benefits, including the fact that there is no risk of generating noise.

Although various preferred embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-mentioned embodiments.
It goes without saying that many modifications can be made without departing from the spirit of the invention, such as that the operation of the actuating rod and the supply operation of the connector do not necessarily have to be continuous.
