A pair of upper and lower molds 71 and 72 of the groove processing means B
As shown in FIGS. 3 and 4, the cable 1 shown in FIG. 721, and the size pitch of these blades is determined by the size of the connector, the pitch of each core of the cable, etc. A pair of the above-mentioned molds is sufficient when cutting a groove in the middle of the cable to press-fit the connector, as shown in Figure 4, but a third mold is sufficient.
In order to cut the cable as shown in the figure and groove both ends at the same time in order to pressure-fit the connectors to both opposing ends, prepare two pairs of the above-mentioned grooving molds as shown in Fig. 5, and insert a cutting blade between them. It's good to be prepared. That is, two adjacent pairs of groove machining molds 71, 71,
A cable cutting blade 73 is provided between the molds 72, 72 and the two pairs of molds in close contact with both. The lower mold also has a receiving blade groove 732 for receiving this. Here, the two pairs of blades and the cutting blade are arranged so that there is no need to change the mold when grooving the middle of the cable and when grooving the end.
is fixed to one of the upper molds 71, and the other upper mold is made to move independently of this. In other words, in the case of intermediate groove machining (Fig. 4), only the upper mold without the cutting blade is lowered, and in the case of end groove machining (Fig. 3), the upper mold without the cutting blade and the upper mold with the cutting blade are lowered. and descend at the same time.

Next, the pressure contact means C, after groove machining, groove machining means B
Instead of moving to the processing position and press-fitting the connector 2, the plural covered wires 12 separated and formed by the groove processing are press-fitted into the groove 21 of the connector 2, and the core wire 13 is inserted into the contact piece of the connector 2. 22, and a support body 82 that supports the connector 2 from behind during the press-fitting.

In the embodiment of FIG.
23, a clamp 821 that rotates around a pin 824 and presses the connector 2 supplied into the groove 823 from the side, and a tapered body 825 that moves up and down to operate the clamp.
etc. The support body 82 having such a structure is connected to a drive body (not shown) so that it can be lowered after clamping the connector 2 until the connector is brought into contact with the upper surface of the pressing body 81 .

In the embodiment shown in FIG. 6, the pressing body 81 includes a guide body 811 having teeth 813 that come into contact with the tips of the protrusions 23 forming the grooves 21 of the connector 2;
3 and a pressing piece 815 having pressing teeth 816 for press-fitting the coated wire into the groove 21 of the connector.

The pair of the pressing body 81 and the support 82 form a pressure contact means C, and when a groove is formed in the middle of the cable (Fig. 4) and a connector is pressed therein, the pair of the pressure body and the support body 82 are sufficient. However, when the cable is cut and grooved as described above (Fig. 3) and two connectors are pressed together, two pairs of pressing bodies are used correspondingly, similar to groove processing means B. A support is provided. Furthermore, after cutting the cable and forming grooves, if you want to press the connector on one side and strip the coated wire 12 on the other side, use only one pair of the above-mentioned two pairs of pressing body and support body, and use the other pair. Instead, a peeling means 9 shown in FIG. 8 is combined. The peeling means 9 includes an upper blade 9
1 and a lower blade 92, and both blades have a groove 9 that is large enough to leave only the core wire 13 of the cable when the two blades are engaged.
3.94. Double edged 91, 92
As shown in FIGS. 8 1 and 2, the upper blade 91 descends and engages with only the core wire 13 in the groove of the blade, and then moves laterally, in the Z direction in FIG. 1, as if stripping off the coating.

Now, the above-mentioned position setting means D, after the feeding means A sets the cable 1 to the processing position P, sets the groove processing means B to the processing position P during grooving, and sets the pressure welding means D to the processing position P during connector pressure welding. It has a structure that encourages In FIG. 1, the means D
holds the groove processing means B and pressure contact means C so as to hold them, and moves reciprocatingly in the Y direction to position the groove processing means B and pressure contact means C at a processing position P according to the processing process. Although not shown, the reciprocating movement of the position setting means D is performed by a programmed pneumatic cylinder or the like.

In the figure, reference numeral 21 denotes a connector feeder that feeds the connectors 2 to the pressure welding means C one by one.

Next, the operation of the present invention configured as described above will be explained.

First, when the cable 1 is passed through the feeding means A, the roll 62 feeds the cable 1 to a processing position P, and sets the cable 1 at the processing position P according to a pre-memorized program.

Next, the position setting means D brings the structure processing means B to the processing position P. At this time, the connecting portion 11 of the cable 1 is connected to the groove machining upper mold blade 71 of the groove machining means B.
1, that is, located in the groove 721 of the lower mold. In this state, the upper die 71 descends. At this time, one upper mold 71 is used when cutting a groove in the middle of the cable to press-fit the connector, and two upper molds are used when cutting the cable and press-fitting the connector to both ends, or press-fitting one end and stripping the coating from the other end. The molds 71, 71 descend together with the cutting blade 73, and together with the lower mold 72, the third and fourth molds
The groove machining as shown in the figure is completed.

When the groove machining is completed, the position setting means D then brings the pressure contact means C to the machining position P. When the pressure contact means C is located at the processing position P, the support body 82 of the means C
The connector 2 is inserted into the groove 823 from which the tapered body 825 is raised and the clamp 821 is released. After that, the tapered body 825 descends and the clamp 821
to firmly support the connector 2 in the groove 823. In such a state, the support body 82 is such that the tip of the protruding piece 23 of the connector 2 touches the guide body 8 of the pressing body 81.
It descends until it comes into contact with No. 11 teeth 813. Then, the pressing piece 815 of the pressing body 81 rises, and its pressing teeth 816 pass through the groove 812 of the guide body 811 and enter the groove 21 of the connector. At this time, since each coated wire 12 of the cable is placed on the groove 812 of the guide body 811, the pressing teeth press the coated wire 12 into the groove 21 of the connector. The contact piece 22 forms a blade-shaped groove slightly narrower than the diameter of the core wire 13 in the groove 21 of the connector, so by press-fitting the covered wire, the contact piece 22 cuts into the covered wire 12 and inserts the core wire 13 into the groove. I bite into it tightly. In other words, the pressure welding is completed.

In the pressure welding of the connector mentioned above, when the connector is pressure welded in the middle of the cable, a pair of pressing body and support body are used.
Further, when the cable is cut and the connectors are press-fitted to both ends, the two pairs of pressing bodies and supporting bodies operate as described above.

Next, when cutting the cable and press-fitting the connector to one end and exposing the core wire at the other end, one of the two pairs of pressing bodies and supports can be replaced with the peeling means 9 described above. conduct. That is, when the pressure-welding means C of this combination operates, the connector is pressure-welded at one end of the cable by the pressing body 81 and the support body 82 as described above, but at the other end of the cable, the upper blade 91 and the lower blade of the peeling means 9 92 is the groove 9
3, 93, leaving the core wire 13 in the coating 12. In this state, the double blades 91 and 92 move in the direction of the cut end (Z direction) of the cable, and the coating 12 is peeled off.

As described above, the present invention is configured to automatically set the pressure welded part of the cable connector to the processing position, apply grooves to the pressure welded part, and then perform pressure welding. Since it is now possible to automatically perform groove processing and pressure welding of connectors even in the middle of the cable with a single device, it has become possible to unify the device and improve work efficiency. . In addition, it is possible to press the connector to one end of the cable where it is to be cut and simultaneously peel off the coating from the other end, making it possible to diversify the work.
