An electric contact for an electrical plug connection includes a receptacle open against a plugging direction and adapted to receive a mating contact in the plugging direction and a plurality of roller contact bodies made of an electrically conductive material and projecting into the receptacle. The roller contact bodies are rotatably held on at least a pair of opposing sides of the receptacle and each form a part of a contact surface adapted to contact the mating contact.

The present disclosure discloses a power-taking device for a rail guide vehicle. The rail guide vehicle includes a chassis travelling mechanism and a loading mechanism including a fixing plate, a power plate, an extension plate and a shifting fork, the fixing plate is fixed to the chassis travelling mechanism, the power plate and the extension plate can be translated, and the shifting fork is coupled to, can be translated in synchronization with, and can be rotated with respect to the extension plate. The power-taking device includes: a first conductive part, fixed to the fixing plate; a second conductive part, fixed to the power plate; and a third conductive part, fixed to the extension plate. When the first, second and third conductive parts are in contact, the power-taking device is turned on.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity.

A power connector assembly includes a power rail having a power supply circuit being configured to be mounted within an equipment cabinet and a sliding power connector configured to be terminated to a host circuit board. The sliding power connector has a power contact electrically connected to the power supply circuit of the power rail. The sliding power connector is configured to be slid along the power rail as an equipment rack holding the circuit board is opened and closed during an extension cycle of the equipment rack. The power contact maintains electrical connection with the power rail during the entire extension cycle.

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.
