摘要： PROBLEM TO BE SOLVED: To reduce the number of ears over the whole route and to prevent breakage of a strand in a branch line by providing an ear, which is installed in the free end of an arm mounted in a steady pipe for a movable bracket and can clamp a trolley line, and connecting the branch line branched from a feeder to the base part of the arm. SOLUTION: A movable bracket, which is supported oscillationally in the upper part of a column raised on the ground and includes a horizontal pipe H and a slanting pipe S, is provided, and on the free end side of the movable bracket, a steady pipe 1 is supported horizontally. An arm 3 is locked in the steady pipe 1 via a supporting metal fitting 2, while an ear 4 is arranged in the lower end of the arm 3. On the other hand, a branch line 5 branched from a feeder is connected to the base part of the arm 3 via a metal fitting 6, and an auxiliary branch line 7 is pulled out from the free end part of the arm 3 via the metal fitting 8 so as to be connected to the ear 4. In this constitution, an ear dedicated for a branch line in the vicinity of a movable bracket is dispensable, and the number of ears in the whole route can be reduced to one third of that in a conventional one.

摘要： PROBLEM TO BE SOLVED: To provide a section insulator that rigidifies a connection between a metal connector and a trolley wire and relatively facilitates the connection work. SOLUTION: The section insulator 1 has the metal connector 3 for retaining an end of the trolley wire T1, T2 passed in a passing hole 8, a wedge tube 4 for gripping the trolley wire on the metal connector 3, and a push nut 5 for pressing the wedge tube in the metal connector 3. The passing hole 8 has a internally taper portion 8a. The wedge tube 4, whose inside diameter is capable of expansion and constriction, is fitted on the end of the trolley wire, and when pressed in the passing hole 8, is radially constricted to grip the trolley wire. The push nut 5 in a state fitted on the trolley wire is threaded through the passing hole 8, so that the tip presses the wedge tube 4 in the passing hole 8. Although the trolley wire T1, T2 is continuously tensioned in the direction to pull it out of the passing hole 8 of the metal connector 3, the tension in the direction pulls the wedge tube 4, 14 in the passing hole 8 to increase the trolley wire gripping force thereof.

摘要： PROBLEM TO BE SOLVED: To read the amount of displacement of a trolley line due to the push-up of a pantagraph on a hanger bar. SOLUTION: A slider S is a couple of a pair of opposite guide plates Sa, which can be slid along a tape-shaped hanger bar, connected in one piece by a sideward arm Sb and an inward elasticity is given to the arm Sb so that a U-shaped hanger bar can be pinched. By placing it to the hanger bar, the slider S does not rise since it is blocked by an auxiliary suspension line even if the hanger bar is pushed up when a vehicle passes and the slider S goes down as it is after the vehicle passes, thus determining the amount of pushed on the hanger bar.
