Maximum major diameter of the methodological null wire connection of the installation of the built-up member of 1 pair for coating tube formation

摘要

PROBLEM TO BE SOLVED: To provide a pair of combination members for forming a covering tube for an electric wire connection part which is used when the maximum outer diameter dimension of the electric wire connection part is larger than the substantial minimum inner diameter dimension of the covering tube.;SOLUTION: The pair of the combination members is constituted of a first cylindrical member 10 and a second cylindrical member 20, the first cylindrical member includes a first small diameter core member 15 attached into an opening of one end thereof and having a diameter expanding action, the second cylindrical member has a second small diameter core member 25 attached into the opening of the one end thereof and having the diameter expanding action, and a large diameter core member 26 attached to the opening of the other end thereof and having the diameter expanding action, and such core members are removable when being attached so as to cover the electric wire connection part. By removal of the large diameter core member, the outer diameter site of the other end of the first cylindrical elastic molded product is fitted and fixed to the inner diameter site of the other end of the second cylindrical elastic molded product. By the removal of the first small diameter core member and the second small diameter core member, the other end of the first cylindrical elastic molded product and the other end of the second cylindrical elastic molded product are brought into close contact with a sheath which covers the electric wire.;COPYRIGHT: (C)2010,JPO&INPIT
