Description

Technical Field

[0001] The present invention relates to the technical field of optical cable detection, and in particular to a detection device for the secondary sheathing bulge of an optical cable. Background Art

[0002] A communication optical cable is composed of a cable core formed by several optical fibers and an outer sheath. The optical fiber has the characteristics of much larger transmission capacity, less attenuation, longer transmission distance, smaller volume, lighter weight, no electromagnetic interference and low cost. At present, it is widely used in signal transmission in various departments such as telecommunications, electric power, and broadcasting, and is the main carrier of future communication networks. In the manufacturing process of communication optical cables, due to the limitations of processing technology, it is very easy to generate tube bulges due to the secondary sheathing process, which may cause the tubes to rupture in the next process, resulting in relatively large losses. The existing detection devices for secondary sheathing upper bulges have complex structures, limited applicable outer diameter sizes of optical cables, require multiple molds of different sizes, and also need manual adjustment and replacement, with troublesome operations and high later use costs.
