Abstract
PURPOSE: To eliminate electrical weak point at the connection sleeve end by manufacturing the terminal portion of negative pole shield and the surface shape of the conductor sleeve for connecting conductors so as to have a slope represented by a specific equation.
CONSTITUTION: When the conductors 3 and 3' of the cables 1 and 1' are connected with the conductor sleeve 4, the sleeve is then covered with the reinforcing insulating layer 5, the insulating layer is then covered with the reinforcing insulating layer 6 and the shield 7, and lastly the conductors are covered with the sheath metal tube 8 and then connected to the cables 1 and 1', the terminal portion of the shield 7 is given a slope represented by the equation, X-V/(I-log Ro/r/log y/r), and also the surface condition of the sleeve 4 is formed in a form represented by the equation, X=V log Rj/Ro(I/log Rj/y-I/log Rj/r). Thus, the layer-directional stress from the slope treminal of the conductor sleeve to the end portion of the reinforcing insulating layer is equally distributed in electric field, thus eliminating an electric weak point at the end.
