Description
Technical Field
The invention belongs to the field of optical fibers, and particularly relates to a stable optical fiber stripper.
Background
The common use method of the optical fiber stripper is that an optical fiber to be stripped extends into the optical fiber stripper, the length of the extending optical fiber is adjusted through the limiting unit, the upper base is rotated to approach the lower base until the upper base is parallel to the lower base, the blade cuts the optical fiber, so that the outer skin of the optical fiber is cut off, and as the inner core of the optical fiber is protected, a notch is reserved at the cutting end of the blade, the shape of the notch is circular, and the diameter of the notch is slightly larger than the diameter of the inner core. This is done to prevent the inner core of the optical fiber from being damaged by the blade, so after cutting the optical fiber, the inner core exposed at the break always covers a layer of outer sheath, and the operator needs to pull the optical fiber and the optical fiber stripper to twist or stretch the same after cutting, and twist or stretch the layer of the excess outer sheath.
When the sheath is cut, an operator can adjust the length of the sheath extending into the peeler according to the required length, although the limiting device limits the extending length of the sheath to enable the extending length to be controllable, the limiting device can be moved, and due to the flexibility of the optical fiber, the optical fiber can be bent to measure the extending length, so that the measuring result is inaccurate; when the remaining sheath is pulled apart, the optical fiber may be bent to damage the inner core, and it is necessary to ensure that the involved sheath is pulled apart again in a straight state.
However, when the length of the single cutting of the sheath cannot reach the required length, secondary cutting is needed, and at the moment, part of the optical fiber extending into the stripper is connected with the exposed inner core after the first cutting, so that the general limiting device cannot accurately measure the length of the sheath during the secondary cutting, and the inner core and the limiting device are possibly interfered and bent to cause damage to the inner core, and thus the damage is not paid.
