Abstract

PURPOSE:To prevent the failure of insulators during laying by providing a protection cover that can fix boots to the outer side of insulators of a joint box. CONSTITUTION:Boots 2, 2a are passed beforehand to the terminals of cables 1, 1a and a protection cover 8 is passed onto one side. Next, the cable ends are shaped, and cable tensile wires 19, 19a are detaine to anchors 5, 5a. An insulator 7-1 or 7-2 and an insulator 3 of the cable are molded by means of continuous molds 4, 4a. A pressure-resistant cylinder 6 is then airtightly fixed to the anchor 5 by means of a bolt 23. Thereafter, the insulator 7 and an insulator 7-1 are continuously molded by a molding part 13. During the molding work, the connection of optical fibers 21, 21a and the refinforcing of the juncture part and fixing to a cage 24 are carried out. After the completion of these, the anchor 5a is airtightly fixed and molded to the opening end side of the cylinder 6. Finally, the cover 8 is inserted onto the outer circumference of an insulation cylinder 7, and the boots 2, 2a are fixed to the covers 10, 10a at both ends.
