The present invention has been made in view of the above problems, and it is possible to easily and accurately determine the state of insertion into a connector by visual inspection or the like, and prevent a connection failure from occurring. It aims at providing the tape electric wire which can be.

[0008]

[Means for Solving the Problems]

 The tape electric wire according to the present invention is a tape electric wire that is used by connecting a plurality of thin-film conductor portions arranged in parallel with each other in a tape shape by being covered with an insulating material and connected to a connector. A feature is that a mark is provided at a position corresponding to the connector insertion depth from the tip.

[0009]

[Action]

 In the present invention, a mark is provided at a position corresponding to the depth of the tape wire connector. This mark is, for example, a notch provided at both ends in the width direction of the tape electric wire or a small hole or a dimple (dimple) provided between the conductors. Depending on the positional relationship between the surface of the connector and this mark, the tape It is possible to easily and accurately judge by visual inspection whether or not the electric wire is sufficiently inserted into the connector.

Such a mark can be formed, for example, by pressing with a die. In this case, for example, when cutting a long tape electric wire to a predetermined length with a cutter blade, a punching die or the like that interlocks with the cutter blade is provided, and a marker is cut at the same time when the tape electric wire is cut by the cutter blade. If it is formed, it is possible to avoid an increase in the number of manufacturing steps.

【Example】

 Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing a tape electric wire according to a first embodiment of the present invention. The tape wire 10 is formed by arranging a plurality of conductor portions 1 in parallel with each other and covering the conductor portions 1 with an insulating material 2 as in the conventional case. Then, at the end of the tape electric wire 10, the insulating material 2 is peeled off to expose the conductor portion 1, and the reinforcing plate 3 is attached to protect the conductor portion 1.

Notches (notches) 4 are provided on both sides in the width direction at a position separated from the end of the tape electric wire 10 by a predetermined distance L. This distance L is set according to the depth of the connector so that the surface of the connector and the position of the notch 4 are aligned when the tape electric wire 10 is properly inserted into the connector.

In this embodiment, notches 4 are provided on both sides of the tape electric wire 10 in the width direction according to the depth of the connector. Therefore, for example, when the tape electric wire 10 is obliquely inserted into the connector, the position of the notch 4 on one side is displaced from the surface of the connector, and the defective insertion into the connector can be easily determined visually. On the other hand, when the tape electric wire 10 is inserted into the connector in a good state, the position of the notch 4 matches the position of the connector. Therefore, in the tape electric wire according to the present embodiment, it is possible to easily and accurately visually judge whether the insertion state into the connector is good or bad.

FIG. 2 is a schematic diagram showing a method of manufacturing a tape electric wire for connecting a connector. The long tape electric wire 11 is wound in a coil shape in which the insulating material is peeled off at a predetermined interval to expose the conductor portion. The exposed portion of the conductor portion of this long tape electric wire is detected by electrical or optical means, and the center of the conductor exposed portion is cut by the cutter blade 12.

When manufacturing the tape electric wire according to the present embodiment, a punching die that interlocks with the cutter blade 12 is provided, and the tape electric wire 11 and the tape electric wire 11 are cut at the same time as cutting with the cutter blade 12 by the punching die. Notches are formed on both sides of the tape electric wire 10 in the width direction. As a result, the distance from the end of the tape wire to the notch can be made constant, and an increase in the number of manufacturing steps can be avoided.

FIG. 3 is a plan view showing a tape electric wire according to a second embodiment of the present invention.

In this embodiment, the small hole 4a is provided between the conductor portions 1 of the tape electric wire 10a, and the distance L from the end of the tape electric wire 10a to the small hole 4a is set according to the connector depth. There is. In the first embodiment, when the number of conductors of the tape electric wire is different (that is, when the width of the tape electric wire is different), the die for forming the mark (notch) is adjusted according to the width of the tape electric wire. There is a need. However, in the present embodiment, assuming that the conductor portions are arranged at the same pitch, the present invention is applied to various tape wires having different widths by a die for forming a mark (small hole) corresponding to the tape wire having the widest width. It's done and you don't have to adjust the mold. Therefore, in this embodiment, when various tape electric wires having different widths are manufactured on the same manufacturing line, there is an effect that the manufacturing is easy.

In addition, in the above-described embodiment, the case where the small hole is formed between the conductor portions has been described, but a depression (dimple) may be formed instead of the small hole. Also in this case, the same effect as that of the above-described embodiment can be obtained. Further, the mark is not limited to the notch, the small hole and the dent, and may be, for example, a line formed by printing.

[0020]

[Effect of device]

 As described above, since the tape wire according to the present invention has the mark at the position corresponding to the connector depth from the tip, it is possible to easily and accurately visually judge the quality of the inserted state in the connector. You can Therefore, it is possible to prevent the occurrence of connection failure.
