FIG. 1 is a front view of an insulated trolley wire current collector showing a first embodiment of the present invention. As shown in FIG. 1, the insulated trolley wire current collector includes a current collector 2, a current collector holder 3 that holds the current collector 2, and a rotating shaft that supports the current collector holder 3 with a holder-support shaft 6. The main components are a rotating cylinder 4 containing a rotating cylinder 5 and an arm block 7 having a parallel link mechanism for elastically moving the rotating cylinder 4 up and down, and current is collected from an insulating trolley wire via a current collector 2. Electric power is led to a power supply unit of a mobile device (not shown) by a lead cable 31 attached to the current collector holder-3. The present invention is characterized in that the positions of the current collector holder 3 for holding the current collector 2 and the holder-support shaft 6 for coupling the rotary cylinder 4 are changed. That is, the position of the holder support shaft 6 and the distance l 2 between the holder support shaft 6 and the end of the current collector holder near the arm block 7 are determined by the distance between the end of the current collector holder and the end opposite to the arm block 7. distance is of providing a l 1 becomes smaller than the position.

With such a structure, even if the current collector holder 3 rotates and tilts in a direction approaching the arm block 7, the tip of the current collector holder 3 on the arm block 7 side moves. The amount is determined by changing the holder-support shaft 6 to the current collector holder-3.
Is smaller than that of the structure located at the central portion in the longitudinal direction of. Accordingly, even if the inclination angle of the current collector holder 3 is increased, the current collector holder 3 and the upper arm 8 of the arm block 7 do not interfere with each other, and the operating range of the current collector 2 is accordingly reduced. Since it can be large, the followability to the insulated trolley wire can be improved. This advantage is particularly remarkable in a large-capacity insulated trolley wire current collector using a long current collector. The ratio between l 1 and l 2 depends on the total length l of the current collector holder 3, the set inclination angle θ of the current collector holder 3, the distance L between the current collector holder 3 and the arm block 7, and the like. I can decide.
