Title:
DIAMETER ENLARGING AND RETAINING DEVICE FOR CYLINDRICAL MEMBER, AND ENLARGEMENT AND REDUCTION OF DIAMETER
Document Type and Number:
Japanese Patent JP3824799
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate such operations as to form and melt a low-melting-point substance solidification layer, by using a cylindrical guide member having a diameter reduction part and a cylindrical hard inserting member having a diameter a little smaller than the inner diameter of the guide member.
SOLUTION: A hard inserting member 20 and a guide member 10 are pulled out sequentially little by little. When the hard inserting member 20 and guide member 10 are pulled out sequentially little by little, the self-shrinkage force of a cylindrical member 30 pushes out the guide member 10, so that the guide member 10 can be pulled out easily. An antifriction is applied to the outer surface of the diameter reduction part 10C of the guide member 10, so that the guide member 10 can be pulled out more easily. When all of the hard inserting member 20 and guide member 10 are pulled out, the condition of diameter enlargement is released, and the cylindrical member 30 is closely fixed to the prescribed position of the terminal of a power cable by self- shrinkage force.
