Description

Take pay-off of removable overcoat

Technical Field

The invention relates to a reel pay-off device, in particular to an optical fiber pay-off device with a replaceable outer sleeve.

Background

In the process of trimming the optical fiber distribution, due to the large number of optical fiber distributions, the optical fiber distribution is usually trimmed by matching with a pay-off device. At present, passive pay-off devices are widely applied in the industries of optical fibers, cables and the like, but most passive pay-off devices have simple structures, are not in place for protection, are in a bad use environment, and do not consider the problem that the optical fibers are shaken when being changed from a winding state to a straightening state to influence the wiring environment in the arrangement situations of long distance, high altitude and the like of the optical fibers.

In order to solve the problem of optical fiber wiring, in the mechanical damping type passive pay-off device disclosed in patent document 1, a passive pay-off reel 10 for cable pay-off is provided, but there is no consideration that the optical fiber may work in a severe environment and the optical fiber may not be protected well.

Accordingly, in order to protect the optical fiber, in the optical fiber winding device disclosed in patent document 2, the housing 10 for protecting the optical fiber is provided outside the movable core 20, but the housing is not versatile and cannot be replaced, and there is no consideration of a problem that the optical fiber is shaken when the optical fiber is changed from the wound state to the straightened state to affect the wiring environment in the case of arrangement of the optical fiber at a long distance, high altitude, or the like.

In patent document 3, an optical fiber performance test mechanism is disclosed, and a damping device 40 for optical fiber vibration is disclosed, but the damping device 40 is provided independently, and the damping device is only a simple cylinder type structure, and cannot be well matched with a reel for damping vibration, and the structure is complicated, and the optical fiber enters the damping device along the reel axis direction, and the main problem to be solved is that the damping is performed when the optical fiber is vibrated due to torsion generated by torsion after being discharged along the reel axis direction, and the problem of vibration generated by self gravity when the optical fiber is discharged along the direction perpendicular to the reel axis direction because the distance of the optical fiber arrangement is long is not considered, and the problem of vibration generated when the optical fiber is transversely moved on the reel due to being discharged is also not considered, and more importantly, the damping effect is not very good. Meanwhile, the damping device 40 can only damp an optical fiber with a specific diameter, but cannot damp an optical fiber with a larger diameter, or has a poor damping effect when the damping device is used for an optical fiber with a smaller diameter.
