PURPOSE:To prevent the damage arising from the physical properties intrinsic to an optical signal cable that its mechanical strength and to improve installation workability by providing the above fixture with an optical signal cable housing part and an optical signal cable winding part. CONSTITUTION:The optical signal cable housing part 100 is formed as a cylindrical shape and its one surface is formed as a surface to be mounted on a transmitter and a receiver. A mounting seat 1a is formed at its center. The surface facing the mounting surface 1 is opened and the optical signal cable winding part 2 is formed therein. The winding part 2 has a cylindrical shape having a radius larger than the min. bending radius of the optical signal cable. As a result, the optical signal cable is wound by the bending radius corresponding to at least the radius of the winding part 2 of the housing part 100. The outer periphery of the housing part 100 is provided with plural pieces of U-shaped slits 3a and, therefore, the arbitrary selection of the inlet and outlet of the optical signal cable to the housing part 100 is possible. The easy fine adjustment of the positions of these slits 3a is possible as well. |
