Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is used for internal wiring of electronic equipment,
The present invention also relates to a tape electric wire that can be inserted into a connector with a single touch, and particularly to a method for manufacturing a tape electric wire that is provided with reinforcing plates at both ends.

[Prior art]

Conventionally, as tape electric wires having reinforcing plates at their terminals, those shown in FIGS. 5 and 6 and those shown in FIGS. 7 and 8 are known.

The tape electric wire shown in FIGS. 5 and 6 is
The conductor exposed surfaces at both ends are facing the same direction, and the upper and lower two plastic tapes 2A, 2
Between B, a plurality of conductors 1, 1, . . . are held integrally and parallel to each other at a constant pitch P.
Each conductor slightly protrudes from both ends of these plastic tapes, one side of these conductors is lined with a third plastic film to form a reinforcing plate 4, and the other side has exposed conductors. Section 3 is constructed. The method for manufacturing the tape electric wire is as follows.

As shown in Fig. 9, a plurality of long conductors 1, 1, . ing.

Each conductor is exposed at the distance l, and a plastic film is bridged on one side of each exposed conductor in the same direction, that is, upward in the illustrated example. Then, the reinforcing plate 4 is fixed. The intermediate material of the tape electric wire constructed in this way is moved in its longitudinal direction, and the cutter 5A, which is raised and lowered approximately at the center of the interval 1, is sequentially pressed onto the receiver 5B to cut it into individual tape electric wires. configured to do so.

On the other hand, in the tape electric wire shown in FIGS. 7 and 8, the reinforcing plate 4 is attached in different directions at the left end and the right end, and the manufacturing method for this tape electric wire is also the same as that described in the above-mentioned ninth method. The tape is cut into individual tape wires in the manner shown in the figure.

[Problem that the invention seeks to solve]

However, the cutter 5A and the receiver 5 are not able to handle the intermediate material in which the reinforcing plate mounting direction is alternately changed from upper, lower, and upper for each gap 1.
When cutting into individual tape wires using B, if the cutter contacts the exposed conductor side and cuts it, then cuts the reinforcing plate and cuts into individual tape wires, it is acceptable. However, it has been found that if the cutter comes into contact with the reinforcing plate and cuts it and then cuts the conductor, the conductor and the reinforcing plate will separate.

Therefore, if the intermediate material of the tape wire, in which the reinforcing plate attachment direction changes alternately upward, downward, and upward for each gap 1, is cut using the conventional cutting method, one end of each tape wire In this case, the conductor and the reinforcing plate inevitably separate from each other.

In order to avoid this drawback, first cut the part where the conductor is exposed on the cutter side, that is, the part where the reinforcing plate is located on the cradle side, and then turn these intermediate materials over and place them on the cutter side. It is considered that the reinforcing plate that was previously used is placed on the pedestal side and then cut again, but this method increases the number of man-hours and has the disadvantage that continuous cutting cannot be performed.

This invention has been made in order to advantageously solve the above-mentioned drawbacks, and the present invention has been made in order to advantageously solve the above-mentioned drawbacks. It is an object of the present invention to provide a method for manufacturing a tape electric wire that can be continuously cut into individual tape electric wires without causing separation between the tape wire and the reinforcing plate.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is constructed as follows.

In the first invention, a plurality of long conductors 1, 1, . . . are arranged parallel to each other at a constant pitch, and a pair of upper and lower short plastic tapes 2A, A plurality of sets of conductor parts 2B are covered with each other so as to form conductor exposed parts 3 with a constant gap l, and a reinforcing plate 4 made of plastic tape is fixed to one side of the conductor exposed parts, and The intermediate material 5 of the tape electric wire, which is configured so that the attachment direction of the reinforcing plate 4 changes regularly or irregularly, is moved in its longitudinal direction, and then the intermediate material 5 is installed in advance on the downstream side of the intermediate material 5. a first cutting device having an upper cutter 6A and a lower receiver 6B disposed oppositely below the upper cutter; and a second cutting device having a lower cutter A and an upper receiver 7B disposed oppositely above the lower cutter. The upper cutter 6 is always moved from the conductor-exposed side of the intermediate material 5 to the position facing the intermediate material 5.
A or a lower cutter 7A is used to sequentially cut the tape into individual wires. Further, in the second invention, a plurality of long conductors 1,
1, . 3, and a reinforcing plate 4 made of plastic tape is fixed to one side of the exposed conductor, and the mounting direction of the reinforcing plate 4 changes regularly or irregularly. The intermediate material 5 of the tape electric wire configured to The intermediate material 5 is guided to the cutting device having the intermediate material 5.
It is configured so that the cutter 8A is always in contact with the exposed conductor side of the intermediate material to sequentially cut into individual tape wires.

[Effect]

Regardless of whether the exposed conductor portion of the intermediate material is located upward or downward, the cutter always contacts the exposed conductor portion from the side and cuts it.

〔Example〕

1 to 3 show an embodiment of the first invention, in which a plurality of long conductors, for example around 10 conductors, for example thin rectangular conductors 1, 1, . . . are arranged parallel to each other and constant. The conductors are arranged at a pitch of, for example, 2.54 mm, and a pair of upper and lower plastic tapes 2A, 2 of a length of, for example, 3 cm to 10 cm are placed on both sides of these conductors.
A plurality of sets of conductor parts B are coated so as to form conductor exposed parts 3 at a constant distance l, for example 10 mm, and a reinforcing plate 4 made of a third plastic tape is provided on one side of the conductor exposed parts. The intermediate material 5 of the tape electric wire is configured such that the reinforcing plate 4 is attached in an upward direction, downward direction, and upward direction alternately for each conductor exposed portion.
is intermittently moved one frame at a time in its longitudinal direction.

When the intermediate material 5 moves one frame and stops, the first cutting device and the second cutting device, which are installed in advance downstream, alternately cut one frame at a time. Here, the first cutting device has an upper cutter 6A and a lower receiver 6B arranged oppositely below this cutter, and the second cutting device has a lower cutter 7A and an upper receiver arranged oppositely above this cutter. It has a tool 7B.

Further, in order to receive the intermediate material 5 between the cutters and receivers of these cutting devices, each cutting device moves alternately in the width direction of the intermediate material 5. That is, as shown in FIGS. 2 and 3,
The cutting devices alternately move in the width direction of the intermediate material so that the cutters 6A and 7A are always located on the exposed conductor side of the intermediate material 5. The timing of movement of each cutting device is set, for example, as follows.

A brush electrode (not shown) is always in contact with the upper surface of the intermediate material 5, and a conductor is grounded at the end of the intermediate material, and when the intermediate material is moved one frame at a time, a conduction signal is generated. If
moving a first cutting device having a cutter upward;
If there is no continuity signal, the second cutting device is moved. In this way, the intermediate material 5 is cut into tape electric wires one after another.

In the above example, the intermediate material is configured to move intermittently one frame at a time, but it may be moved continuously at a constant speed. Furthermore, although an example is shown in which the mounting direction of the reinforcing plate 4 in the intermediate material mentioned above changes regularly from above, downward, and upward alternately, the mounting direction of the reinforcing plate 4 changes irregularly. It may be.

FIG. 4 shows an embodiment of the second invention, in which a pair of cutting devices having a cutter 8A and a receiver 8B are rotated 180 degrees around the center of the intermediate material 5 by the aforementioned signal. After being moved, the intermediate material 5 is cut by the cutting device, but the other structure is the same as in the embodiment of the first invention.

〔Effect of the invention〕

According to this invention, regardless of whether the exposed conductor portion of the intermediate material 5 is located upward or downward, the cutter is configured so that it always comes into contact with the exposed conductor portion and cuts it. Peeling between the conductor and the reinforcing plate can be reliably prevented, and therefore a high-quality tape electric wire with a reinforcing plate can be manufactured.
