はなかった。Conventionally, as a shielded flexible cable, a cable core having an insulator (2) on a conductor (1) is twisted together with a single core or multiple cores, and a shielding tape such as aluminum, copper, etc. is applied to the outside of the cable core.
A shielded flexible cable in which a smooth laminate tape (51) made of lead or the like is attached vertically, a grounding wire (drain wire (4)) is inserted into the tape (51), and a sheath (6) is coated on top of the grounding wire (4). (See Figure 1).However, since the above-mentioned shielded flexible cable uses a smooth surface as the shielding tape, the number of bends before disconnection satisfies the standard value. In addition, the flexibility was not sufficient.
この発明の目的は、前記した従来技術の欠点を解消し、

可撓性ケーブルを提供することにある。The purpose of this invention is to eliminate the drawbacks of the prior art described above,
An object of the present invention is to provide a shielded flexible cable that has improved bending frequency and bending conditions at breakage.

性能を有する。Embodiments of the present invention will be described below based on the drawings. FIG. 2 is a sectional view showing an embodiment of the shielded flexible cable of the present invention, in which a multi-core cable consisting of a conductor (1) coated with an insulator (2) is twisted, and the outer direction a k
A wrinkled aluminum laminate tape (52) is attached vertically as a tape for use, and a run wire (4) is inserted into the tape (52).
2) is covered with a sheath (6). In addition,
(3) It is i'i intercalated jute. FIG. 3 is a perspective view showing an example of wrinkled aluminum laminate tape (52) used in the shielded flexible cable of the present invention. When the Ω cable of the present invention was compared with a conventional product in terms of the number of bends until breakage and flexibility, the results shown in FIGS. 4 and 5, respectively, were obtained. As is clear from Fig. 4, the number of bends when the wire breaks is 8,000 to 12,000 times for the conventional product, which is the standard value (3
0,000 times), whereas with the product of the present invention, the number of times was less than 4
0.000 to so, ooo times, which is significantly higher than the standard value. 1.As for the flexibility (flexibility), as is clear from FIG. Because we used wrinkled tape with waves in the direction perpendicular to the longitudinal direction, the number of bends before breakage and flexibility (flexibility ) will be significantly improved. In addition, wrinkled tape is highly flexible, which improves tape winding workability.
Furthermore, the electrostatic shielding effect is equivalent to or better than that of smooth tape.
