CONDUCTOR CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To reduce temperature rise of conductors by decreasing a heating value of a conductor connection part.SOLUTION: An outer diameter part of an inner peripheral side conductor 4a is adhered and fitted to an inner diameter part of an outer peripheral side conductor 3a. A ring 9 is disposed at a fitting part of the conductors 3a and 4a so as to surround an outer peripheral part of the outer peripheral side conductor 3a. The ring 9 is composed of a material having a smaller linear expansion coefficient than the outer peripheral side conductor 3a. A solid cylindrical member 10 is disposed inside the inner peripheral side conductor 4a in the fitting part of the conductors 3a and 4a. The cylindrical member 10 is composed of a material having a larger liner expansion coefficient than the inner peripheral side conductor 4a. A spring 11a is disposed between the outer peripheral part of the outer peripheral side conductor 3a and an inner peripheral part of the ring 9. A spring 11b is disposed between an inner peripheral part of the inner peripheral side conductor 4a and an outer peripheral part of the cylindrical member 10.
