Title:
CORRUGATED TUBE AND OPTICAL FIBER WITH PROTECTIVE TUBE
Document Type and Number:
WIPO Patent Application WO/2012/164778
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technique whereby a target object can be protected and the curvature thereof can be regulated. To achieve this purpose, a corrugated tube (2) comprises large-diameter sections (21) and groove sections (22) connected alternately in an axial direction, the large-diameter sections (21) and the groove sections (22) being formed into shapes whereby the curvature of the corrugated tube (2) can be regulated. For example, when the corrugated tube (2) is bent from being linear, the large-diameter sections (21) and the groove sections (22) are formed into shapes that enable curvature to be regulated, wherein adjacent large-diameter sections (21) sandwich the groove sections (22) and come in contact with each other in the inner sides of the bent sections, and the groove sections (22) are fully stretched in the outer sides of the curved sections.
