Abstract

A coating removing device includes a main body that includes a blade used for coating removal; a gripping section that grips an optical fiber; and a slider that connects the main body and the gripping section together so as to be able to approach or separate from each other. The coating removing device removes a coating from the optical fiber by separating the main body and the gripping section after an incision has been made in the coating of the optical fiber using the blade. The slider includes a retention unit to retain the main body and the gripping section in a maximum separation state.

First claim

The invention claimed is:

1. A coating removing device comprising:
a main body that includes a blade that removes the coating; a gripping section that grips an optical fiber; and
a slider that connects said the main body and said the gripping section together, wherein the main body and the gripping section approach or separate from each other on the slider, said the coating removing device removes the coating from said the optical fiber by separating said the main body and said the gripping section after an incision is made in said the coating of said the optical fiber using said the blade, said the slider includes a retention unit to retain said the main body and said the gripping section in a maximum separation state, the slider comprises a shaft,
an end portion of the shaft is fixed to one of the main body or the gripping section, the other of the main body or the gripping section includes a sliding section in which the shaft slides,

the retention unit comprises:
a shaft-side engagement portion that is disposed on an end portion of the shaft opposite to the fixed end portion of the shaft, and comprises a taper that becomes thicker toward the end portion of the shaft and an indentation; and
a slide-side engagement portion that comprises a protrusion that engages with the indentation of the shaft-side engagement portion and retains the maximum separation state, wherein the slide-side engagement portion is elastic and deforms when the taper engages with the slide-side engagement portion.

2. The coating removing device according to claim 1 , wherein
retention of the maximum separation state by the retention unit is released when force exceeding weight of the gripping section is applied in a direction to cause the main body and the gripping section to approach each other.

3. The coating removing device according to claim 1 , wherein
the slide-side engagement portion comprises a circular cylinder through which the shaft is inserted,
the protrusion projects from an inner surface of a sidewall of the circular cylinder toward an inside of the circular cylinder, and
a thin walled portion is formed in an outer surface of the sidewall at an outer position on the outer surface corresponding to an inner position on the inner surface where the protrusion is disposed.

4. The coating removing device according to claim 1 , wherein
the indentation is provided further toward the end portion of the shaft than the taper, and
the slide-side engagement portion further includes:
a taper housing that houses the taper.

5. The coating removing device according to claim 1 , wherein the sliding section includes a ball bearing that slidably supports the shaft.

6. The coating removing device according to claim 1 , wherein
the main body includes a placement section on which the optical fiber is placed, and
a length of separation between the main body and the gripping section in the maximum separation state is longer than a length of the optical fiber.
