Claims

[Scope of utility model registration request]

At the terminal connection part of the forced cooling cable, which is formed by connecting the copper conductor of the forced cooling cable, which has the copper conductor on the aluminum tube that serves as the internal refrigerant passage, to the lower end of the conductor pull-out rod that passes through the insulator tube, The conductor pull-out rod is composed of a copper rod that passes through the pipe, and an aluminum rod that is friction-welded to the lower end of this copper rod, and the conductor pull-out rod is made of a copper rod that passes through the pipe and an aluminum rod that is friction-welded to the lower end of the copper rod. The aluminum pipe of the forced cooling cable exposed by step stripping is inserted into the refrigerant circulation passage formed to communicate with the inside of the pipe, and the aluminum pipe of the forced cooling cable is inserted between the outer peripheries of the copper conductors of the forced cooling cable on the outer periphery of the copper rod. A terminal connection part of a forced cooling cable, characterized in that a connecting copper sleeve is inserted into the connecting copper sleeve, and the connecting copper sleeve is compressed or welded at the position of the copper rod and the copper conductor, respectively.
