<p><P>PROBLEM TO BE SOLVED: To provide an insulation tube of a structure capable of easily and stably securing a creepage distance for electric insulation, and of ensuring an improvement in workability in mounting of an insulator to a wire and further compactness. <P>SOLUTION: Partly-open tubes 13, 14, 15 with a plurality of diameters each having slit-shaped openings 13a, 14a, 15a with a part of its periphery notched in the length direction are laminated in a plurality of layers, and a plurality of the partly-open tubes 13, 14, 15 are connected in the length direction for each layer to constitute the insulation tube 11. In connecting the partly-open tubes 13, 14, 15 in a lamination and length directions, positions of the openings 13a, 14a, 15a are shifted in the periphery direction for each adjacent two layers, and moreover, positions of connecting parts 13b, 14b, 15b of the partly-open tubes of each layer in the length direction are shifted in the length direction for respective two adjacent layers. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
