A low-stress optical cable take-up and release device

Abstract

The invention relates to a low-stress optical cable winding and unwinding device which comprises a cable storage disc. The low-stress optical cable winding and unwinding device is characterized in that a cable leading support is installed on one side of the cable storage disc, an optical cable guide tube is installed at the upper end of the cable leading support, and the lower end of the optical cable guide tube is communicated with a rotating guide tube. The low-stress optical cable winding and unwinding device integrates the winding function and the unwinding function into a whole, and low-stress automatic optical cable winding and unwinding functions can be effectively achieved; by means of the elastic rotating guide tube, overlarge acting force and friction force can be absorbed and buffered when the cable threading speed is higher, and overlarge vibration can be avoided, so that a micro cable is in a stable low-stress state in the winding and unwinding process; a telescopic cantilever structure and a detachable vertical rod structure are adopted by the cable leading support, the low-stress optical cable winding and unwinding device can be suitable for and be matched with cable storage discs with different diameters, the rotating guide tube is always in the optimal winding and unwinding position, and the winding and unwinding efficiency is improved; the low-stress optical cable winding and unwinding device further has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The invention discloses a low-stress optical cable take-up and release device, and more particularly relates to a stress-sensitive micro-cable take-up and take-off device. Background technique [0002] Most of the existing optical cables can withstand a certain stress to meet the specified mechanical properties. In the production process of optical cables, most of them are wound on the reel of specified size after being cabled. Due to the tension of the optical cable itself, a certain pre-tightening force must be applied when the optical cable is unwound to avoid loosening of the optical cable. However, for some optical cables with special structures, such as microcables, their diameters are small and they are very sensitive to stress. If they are in a pre-stressed state for a long time, the microcables will be deformed irreversibly, and even cause the microcables to be scrapped. Therefore, some microcables cannot adopt the traditional reel-winding m...

Problems solved by technology

Before construction, the micro-cable needs to be placed in the rewinder before it can be used. There are problems such as unsmooth unwinding, easy to generate stress, single function and large volume, which is inconvenient to use.
