Document Type and Number:
WIPO Patent Application WO/2023/112370
Kind Code:
A1
Abstract:
A pull-end attachment structure (1) comprises: a cable (10) having an optical fiber; a tubular dam case (20) that is fixed to the cable so as to surround the cable; a tubular member (30) to which a hose (100) with a pulling part for accommodating an end of the optical fiber is attached and which is provided so as to surround the outer peripheral surface of the dam case; and a tubular fixed member (40) that surrounds the cable and that can be fixed to the tubular member. An outer diameter (R1) of the fixed member is equal to or less than an outer diameter (R2) of the tubular member. Formed on the inner peripheral surface of the fixed member is a contact surface (43a) that delivers a pulling force to the dam case by making contact with the dam case when the tubular member and the fixed member are pulled by the hose with pulling part.
