Claims

[Scope of utility model registration request]

A flexible main current passage body wound in a coil around a tube having an extensible part, a conductor having an extensible part provided to surround its outer periphery, and a conductor at each end of the potential cylinder. A sheath having an extendable part that surrounds the cable connection part so as to create an insulating gap between the extendable joint part of the cable conductor connected to the first and second connectors and the outer peripheral surface of the conductor potential cylinder. After connecting the first and second connectors to both ends of the cable to be connected, an insulating layer is provided across the cable sheath at both ends and the cylinder for conductor potential, and then the conductor potential is A telescopic joint device for cryogenic cables in which the gap between the sheath potential cylinder and the sheath potential cylinder is filled with liquid refrigerant for connection.
