    • This invention relates to a rotating connector comprising an inner cylinder 2 and an outer cylinder 3 combined together to permit the relative rotation in a concentric state, and a flat cable 1 spirally housed in an annular space 20 formed between the inner cylinder 2 and the outer cylinder 3, and connected at its inner end to the inner cylinder 2 while being connected at its outer end to the outer cylinder 3, wherein the flat cable 1 is composed of a plurality of flat-type conductors 10 placed in parallel arrangement and an insulating coat layer 11 placed over the flat-type conductors 10, and the insulating coat layer 11 is formed by coating the flat-type conductor 10 with a thermoplastic resin by means of direct extrusion. According to the present invention, since the insulating coat layer 11 of the flat cable 1 is formed by coating the flat-type conductors 10 with the thermoplastic resin by means of direct extrusion as described above, it is possible to provide a rotating connector, which permits the smooth rotation without an increase in torque even in the high-temperature environment and is excellent in durability.
    • 本发明涉及一种旋转连接器,其包括组合在一起以允许同心状态的相对旋转的内筒2和外筒3,以及螺旋状容纳在形成于内筒2和外筒2之间的环形空间20中的扁平缆索1 气缸3,并且在其内端连接到内筒2,同时在其外端连接到外筒3,其中扁平电缆1由并排布置的多个扁平型导体10和绝缘体 涂覆层11放置在平面型导体10上,绝缘涂层11通过直接挤出用热塑性树脂涂覆扁平型导体10而形成。根据本发明,由于绝缘涂层11 通过如上所述通过直接挤压用热塑性树脂涂覆扁平型导体10而形成扁平电缆1,可以提供旋转连接器, 这允许即使在高温环境中也不会增加转矩而平滑地旋转并且耐久性优异。
