GLEITENDES LOSTRENNBARES KERNELEMENT UND KALTSCHRUMPFROHRVORRICHTUNG MIT EINEM SOLCHEN ELEMENT

摘要

[Problems] To provide a body section with sufficient rigidity without impairment of the sliding facilitating ability of a sliding section of a slidingly detachable core member included in a cold shrink tube unit. [Solving Means] A slidingly detachable core member 12 includes a body section 22 that forms a hollow cylinder, and a sliding section 24 that is integrated with one axial end of the body section 22 and is so flexible as to be turned over to lie on the outer circumferential surface of the body section 22. The body section 22 consists of a plurality of plate-like portions 26 that are assembled to form the hollow cylinder. The sliding section 24 consists of a plurality of porous structural parts 28 that are formed adjacently to the plate-like portions 26 respectively. The core member 12 is incorporated in a seal region of an elastic tube member included in a cold contractile unit with the sliding section thereof turned over to lie on the outer circumferential surface of the body section 22. The core member 12 has pull tabs 30 that are integrated with the body section 22 while being isolated from the sliding section 24.
