Description
Technical Field
The invention belongs to the field of optical fibers, and particularly relates to a stable optical fiber stripper.
Background
The common optical fiber stripper is used in that an optical fiber to be stripped is stretched into the optical fiber stripper, the stretching length of the optical fiber is adjusted through a limiting unit, an upper base is rotated to trend towards a lower base until the upper base is parallel to the lower base, a blade cuts the optical fiber, the outer skin of the optical fiber is cut off, a notch is reserved at the cutting end of the blade because of protecting the inner core of the optical fiber, the notch is circular, and the diameter of the notch is slightly larger than that of the inner core. The purpose of this is to prevent the inner core of the optical fiber from being damaged by the blade, so that after cutting the optical fiber, the inner core exposed at the break always covers a layer of outer skin, and an operator needs to pull the optical fiber and the light stripper to twist or stretch after cutting, and twist or stretch the redundant outer skin.
When cutting the outer skin, an operator can adjust the length of the outer skin extending into the stripper according to the required length, and although the limiting device limits the extending length of the outer skin to enable the extending length to be controllable, the limiting device can move, and the extending length of the optical fiber is possibly measured in a bending state due to the softness of the optical fiber, so that the measurement result is inaccurate; when the remaining outer sheath is broken, the optical fiber is bent, and the inner core may be damaged, so that it is necessary to ensure that the optical fiber is broken again in a straight state.
However, when the length of the single outer skin cut cannot reach the required length, the secondary cut is needed, and at this time, part of the optical fiber extending into the stripper is exposed with the first cut, so that the general limiting device cannot accurately measure the length of the outer skin during the secondary cut, and the inner core is possibly interfered with and bent by the limiting device, so that the inner core is damaged, and the damage is avoided.
