The trolleybus current collector system described herein comprises a trolley pole, which is attached movably with its bottom part to the trolleybus, while its top part is connected to the outer end, with respect to the direction of driving, of an insulating carrier, onto which there are arranged current collector slide blocks. The pole is connected to the carrier by means of a compression body. The outer current collector slide block is mounted rigidly to the carrier. The inner current collector slide block is mounted movably in longitudinal direction with respect to the carrier. To each current collector slide block there is mounted, by means of respective internally diagonal deflectors, a current-carrying bridge. The compression body is fastened to pole parallel to the supply line.
