Embodiment Construction

[0024] refer to figure 1 , the optical cable end fixing tool according to this embodiment will be described. figure 1 (A) is a diagram showing a state in which the components of the cable end fixing member are arranged at the terminal portion of the optical cable, figure 1 (B) means figure 1 (A) Axial cross-sectional view of the cable end fixture.

[0025] The optical cable end fixing tool 1 is a member for locking and fixing the end portion of the optical cable 2 , and includes a connecting member 3 , a caulking member 4 , and a fastening member 5 . The optical cable 2 has an optical fiber part 6 , a sheath 7 covering the optical fiber part 6 , and a tensile fiber 8 provided between the optical fiber part 6 and the sheath 7 . In addition, although the optical fiber part 6 is a multi-core optical fiber assembly, it is not limited to this.

[0026] The connecting member 3 is connected to and supported by a frame portion of an optical device or the like, guides an optica...

Abstract

A fiber optic cable fixture 1 has a joint member 3, a swaging member 4, and a fastening member 5. The joint member 3 has a cylindrical shape in which a through hole 10 is formed and includes a joint section 11 joined to another member, a male screw 12, and a cylindrical section 13 that is smaller in diameter than the male screw 12 and that is covered with a jacket 7 and tension fibers. The swaging member 4 is fitted to the cylindrical section 13 while covered with the jacket 7. A female screw 16 is formed at one end of an inner peripheral surface of the fastening member 5. A tapered surface 17 is formed on another end of the inner peripheral surface of the fastening member 5.

Description

technical field [0001] The present invention relates to an optical cable end fixing member and an optical cable end fixing method for fixing an optical cable to an optical equipment frame or the like. Background technique [0002] As an end fixing member of an optical cable, for example, an end fixing member 104 of an optical cable 101 is disclosed in Patent Document 1, which is as Figure 7 As shown, the tensile fiber 102 and the sheath 103 of the optical cable 101 are simultaneously fixed by the same component. Specifically, in the state where the sheath 103 of the optical cable 101 and the tension-resistant fiber 102 of the lower layer are disposed on the guide portion 106 of the stop ring 105, the riveting portion 108 of the riveting ring 107 surrounds the sheath 103 and the tension-resistant fiber. 102, riveting the two simultaneously to fix them. [0003] In addition, for example, in Patent Document 2, an end fixing member 204 is disclosed as Figure 8 As shown, the ...
