A current collector for a multi-pole contact line system has a lower arm that is pivotally mounted on a base and at least two upper arms that are pivotally mounted on an end of the lower arm opposite the base. The current collector also has at least two contact assemblies that are arranged on the respective upper arms and are associated with separate different poles of a contact line. The current collector further has a central compensating rocker arranged on the base and at least two connecting rods, the first end of each of which is pivotally connected to the central compensating rocker and the second end of each of which is pivotally connected to one of the at least two upper arms. An electrified transport system uses such a current collector.

Provided is a power supply box device that improves design properties by keeping an operation lever from being visible from outside and that prevents misoperations caused by the operation lever being touched by mistake. A power supply box device 1 that comprises a plug 30: that has an operation lever 31m that protrudes in a radiation direction from a plug main body and extends downward; and that is supported by a lid member so as to be capable of forward and reverse rotation. A box main body has: a housing 12 that houses a power supply; and a lever cover 13 that is supported by the housing 12 so as to be capable of ascending/descending between a lock position that is on an upper side and a lock release position P2 that is on a lower side. The lever cover 13 is arranged in the lock release position P2 to allow the operation lever 31 m to rotate and covers the operation lever 31m by ascending, relative to the operation lever as arranged in a prescribed position, from the lock release position to the lock position.

A track assembly includes a track, a support member, a support member conductor, a first conductor and a plurality of second conductors. The support member conductor may be configured to move substantially laterally and electrically contact the second conductors. The second conductor may be configured to move laterally and electrically contact the first conductor. The support member conductor may be configured to move the second conductor into electrical contact with the first conductor. The first conductor may extend substantially in the longitudinal direction and/or the first conductor may be disposed at least partially in the track. The plurality of second conductors may be disposed such that the support member conductor may be in contact with at least two second conductors of the plurality of second conductors in all positions of the support member relative to the track.

A frangible shunt link assembly includes a frangible link configured to conductively couple a current collector coupled with a vehicle and one or more components of the vehicle. The frangible link is configured to break responsive to the current collector being at least partially separated from the vehicle to interrupt a conductive connection between the current collector and the one or more components of the vehicle.

A power connector assembly includes a power rail and a slide power connector. The power rail is mounted to a first wall of a first component via mechanical standoffs to define a clearance space between the power rail and the first wall. An electrode is disposed along a first side of the power rail facing the first wall. The slide power connector is mounted to a second wall of a discrete, second component. The slide power connector defines a track that receives the power rail therein. At least one power contact of the slide power connector is disposed within the clearance space and is electrically connected to the electrode of the power rail to establish an electrical connection. At least one of the first and second components is movable relative to the other along an extension cycle. The electrical connection is maintained throughout the extension cycle.
