Fiber-optic cable with fitting

摘要

A fiber-optic cable with a fitting capable of increasing connection strength between a fiber-optic cable and an optical connector, which includes a fiber-optic cable including a sheath and a tensile member, an inner ring mounted on a circumference of the sheath from a position where the tensile member is drawn out of the sheath through a slit to a front end of the sheath, and a fitting mounted on the circumference and including a first portion mounted from the position where the tensile member is drawn out of the sheath to a position of the sheath on a side opposite to the ring side, and a second portion mounted while covering a circumference of the ring, wherein the first portion connects with the sheath, and the end portion of the tensile member is sandwiched by the ring and the second portion.

1. A fiber-optic cable with a fitting that comprises:
a fiber-optic cable that comprises: a sheath comprising a slit on an end face thereof in a longitudinal direction, the sheath having,
a first region; anda second region that is arranged closer to the end face in the longitudinal direction than the first region; a tensile member inside the sheath, an end portion of the tensile member drawn out of the sheath through the slit; an inner ring mounted on a circumference of the sheath from a position of the sheath where the tensile member is drawn out of the sheath through the slit to a side of the end face of the sheath; and the fitting mounted on the circumference of the sheath, the fitting comprising:
a first portion having one of a ring shape or a cylindrical shape, and including a through-hole, the first portion mounted on the circumference of the first region of the sheath, from the position of the sheath where the tensile member is drawn out of the sheath through the slit to a position of the sheath that is on a side opposite to the side where the inner ring is mounted; and a second portion having one of a ring shape or a cylindrical shape, and including a through-hole having a larger diameter than a diameter of the through-hole of the first portion, the second portion mounted on the circumference of the sheath while covering a circumference of the inner ring,
the first and second portions having an integral construction, wherein the first portion of the fitting engages in the circumference of the first region of the sheath to connect with the sheath, and the first portion of the fitting and the first region of the sheath are pressed and deformed such that an inner diameter of the first portion of the fitting and an outer diameter of the first region of the sheath are smaller than an outer diameter of the second region of the sheath, wherein the fitting is formed from a metal material wherein the end portion of the tensile member is sandwiched by the inner ring and the second portion of the fitting, and wherein the second region of the sheath is not compressed or deformed.
