Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a stretchable tape electric wire.

Conventionally, tape wires, which are called tape wires, flat cables, ribbon wires, etc., are used to connect devices that are constantly moved, such as computers and microprocessors used therein.
Wt1゛-tsu! When used between terminal devices such as boards, it is required to have good flexibility.

In this case, when the terminal device is moved closer to the main body, the length of the tape electric wires may gather and bend, causing trouble for the operator. The present invention has been made in order to eliminate such inconvenient situations, and provides an apparatus for manufacturing a tape electric wire that has good flexibility and is stretchable in the longitudinal direction. FIG. 1 shows a stretchable tape electric wire manufactured according to the present invention, and this stretchable tape electric wire, indicated as a whole by 1, has a large number of wavy bent portions IA overlapping in its longitudinal direction. It is something that The folding width b of this wave-shaped bent portion IA is appropriately selected to the extent that there is no problem with other parts, and when the tape electric wire is pulled in the longitudinal direction, the curvature ratio of this wave-shaped bent portion IA gradually decreases and is stretched, and when the tape wire is pulled in the longitudinal direction, it is stretched. When the force is removed, the tape wire will return to its original bent state due to its elasticity. If the required elasticity cannot be obtained with the insulating tape alone, a tape-shaped rubber or synthetic resin sheet may be added and, for example, in the case of rubber, it may be vulcanized and fixed in a bent state as shown in FIG. 2 shows a connector, and the conductor W used in this is not only a single ordinary conductive wire, but also a thin synthetic resin fiber core wire and a plurality of thin annealed copper wires arranged and horizontally wound around this wire. It's okay. Next, the present invention will be explained in detail with reference to FIGS. 3 to 7. The pedestal 6 is provided with a pin array base frame 8 of the waveform shaping device. This pin arrangement base frame 8 is a tape electric wire 5 that is fed out from a tape electric wire feed-out bobbin 3 via a pinch roll 4.
A fixing pin 81 is mounted on a parallel member extending in the longitudinal direction of the tape electric wire in a cantilevered state in a direction perpendicular to the direction of the tape electric wire. and a large number of movable pins 82 sequentially arranged at regular intervals in the open state.
These movable pins 82 are biased so as to come into close contact with the fixed pins 81 in the closed state. The mechanism for shifting the movable pins to one side is the same as that in the pin arrangement rotation frame 7 described later, so FIG. 6 will be described together. The pin array rotation frame 7, which is another element of the waveform shaping device, is a frame member whose one end is rotatably supported on the pedestal 6 by a shaft 73, as shown in FIGS. 3 and 5. A fixed pin 71 and a large number of movable pins 72 are provided in the same relationship as the fixed pin 81 and the movable pin 82 in the pin array base frame 8 described above in the longitudinal direction.

As shown in FIG. 6, the movable pins 72, 82 are connected at their respective ends to the chain 12 fixed to one end of the fixed pins 71, 81 with a predetermined open interval. By drawing the farthest movable pins 72, 82 toward the fixed pin, the movable pins closer to the fixed pin are successively pushed to one side by this movable pin. The arrangement rotation frame 7 is then pivoted. When rotated about 73, each pin of the pin array rotation frame and each pin of the pin array base frame are arranged at intervals that allow them to pass alternately. Note that the moving pins 72 and 82 are cantilevered, so when they are in the open state or in the closed state after being moved to one side, the moving pins are attached to the tape electric wire! In order to maintain the position perpendicular to the longitudinal direction, flanges 75, 85 are formed at the base of each pin, and these are guided by grooves provided in the member and having a width slightly larger than the outer diameter of the flange. I will ask you to let me know. In FIG. 8, 74 is a handle for operating the pin array rotating frame 7, and 11 is a lock lever of the rotating frame provided on the pedestal 6. Next, a waveform fixing device for fixing the waveform of the tape electric wire formed by the above-mentioned waveform shaping device will be explained.

As shown in FIG. 7, the pin array base frame 8 and the pin array rotation frame 7 of the waveform forming device can move forward and backward into the position where the tape electric wire 5 is waveformed. (The broken line 13'' indicates its retreat position) and a cooling device 14 that supplies cold water or cold air at that position.The heat source of the heating furnace is electric resistance heat, gas combustion heat,
Any method such as dielectric heating may be used. Next, the operation of this invented device will be explained.

) First, the tape electric wire 5 is fed out from the feeding bobbin 3.
is placed on the pin array base frame 8 of the waveform shaping device, and its left end is held by the first clamp 10. Next, rotate the pin arrangement rotation frame 7 around the shaft 73 so that the movable pin 72 is located below the pin 82, and then move the movable pins 72 and 82 to the respective fixed pins 71 and 81. Move to one side. This is the state shown in FIG. At this time, the pinch roll 4 serves as a brake roll that applies tension to the tape electric wire. Next, after activating the second clamp 9 on the downstream side of the tape electric wire, the heating furnace 13 is moved to the forming part as shown in FIG. Move the heating furnace 13 to the retracted position 13''
After the molded part is evacuated, the cooling device 14 is activated to fix the molded part. Next, as shown in FIG. 5, the pin array rotating frame 7 is moved in the axial direction along the shaft 73 to the position indicated by the broken line in the figure, and then the pin array base frame 8 is opened and the interval between the movable pins 82 is adjusted. Expand.

After this, the first and second clamps 10 and 9 are released,
The completed tape electric wire 1 can be pulled out to the left as shown in FIG. The manufacturing apparatus of the present invention has the advantage of being able to continuously and efficiently manufacture the above-mentioned stretchable tape electric wire.
