PURPOSE:To reduce a span of working time and dispense with a nut as well as to solve a problem of nut-whirling in time of clamping, by installing a pressure terminal setting tapped hole in a conductor joint. CONSTITUTION:Each bending piece 21 of a conductor 12 of both insulating trolley lines 1 passes through each conductor insert hole 25 and is superposed on each other, then connected with each conductor joint 21 which is provided with a U-shaped joint body 27 having upper and these conductor insert holes 25 in both upper and lower pieces and a conductor locking screw 28. A pressure terminal setting tapped hole 32 is formed in a extension piece 27a of this upper piece part. Each of these bending pieces 12a of the conductor 12 passes through the conductor insert hole 25 in a state of being superposed on each other, and tightly locked in a superposed direction with a lock screw 28 A feeder line 33 forcedly presses a pressure terminal 34 to the end part, and a locking screw 36 inserted into its insert hole 35 is screwed in the tapped hole 32 of the conductor joint 21 whereby it is connected to the conductor joint 21. Therefore, drilling for setting the pressure terminal on the spot is no longer required for the conductor, thus working time is reduced and, what is more, a problem of whirling in time of clamping is solved.
