摘要:
A terminal accommodating portion is disposed on a front side or a rear side in a traveling direction of the wheel that travels between the pair of side walls of a rail, and is attached to the moving device. A power receiving terminal receives electric power to be fed to a secondary battery, and is provided to be movable along a width direction. A terminal receiving portion is groove-shaped and is provided in one side wall of the rail, and the power receiving terminal configured to move along the width direction of the moving device is inserted into the terminal receiving portion. A power transmitting terminal is disposed on a surface, inside the terminal receiving portion, on which the power receiving terminal slides during movement, is present over a longitudinal direction of the rail, and comes into contact with and transmit power to the power receiving terminal.

An example electrical connector includes a non-electrically-conductive housing carrying at least a pair of opposed flexible, electrically-conductive push-in type contacts. The contacts each having a first end configured to receive and grip an electrical conductor, and a second end having a contact portion to releasable electrically couple with a corresponding conductive strip housed on opposite sides of an upper rail of a corresponding low voltage direct current grid member. In one example, a strain relief mechanism is coupled to the housing and is adapted to mechanically couple to the inserted electrical conductor and to assist in retaining the inserted electrical conductor in the push-in type contact. The housing may also define at least a pair of first interior spaces enclosing the first end of each of the contacts and for receiving and gripping the electrical conductor.

An assembly distributes electrical power between an electrically active grid element of a grid framework and an electrical device. The assembly includes a grid connector for making electrical contact with a pair of electrical conductors on the grid element, and an adapter mounted on the grid connector. The adapter includes an industry standard interface electrically connected to the grid connector. The interface is adapted to receive a power connector at one end of a power cable whose opposite end is connected to the electrical device.

A lighting system comprising a track having a first and a second rail (5, 7), mutually extending equidistantly. Said first and second rail comprise a first respectively a second electrically conductive strip, mutually electrically isolated. A lighting module (17) comprising a first and second electrical contact, which lighting module in mounted position rests by gravitational force on the first and second rail. When mounted the first and second electrical contact are in electrical contact with a respective one of the first and second electrically conductive strip. The lighting module is dismountable from the track by a single displacement of the lighting module in a direction against the direction of the gravitational force.

The invention relates to a directable magnetic mount (10) for a light emitter (20). The invention also relates to a light source (200), to a base (40) and to an illumination system (100). The directable magnetic mount comprises interface means (30) configured for conducting thermal energy away from the light emitter to a heat sink (40), and comprises a magnetic connector (50) configured for magnetically connecting the directable magnetic mount to the base. The magnetic connector is configured for thermally interconnecting the interface means and the heat sink. The interface means is configured for being thermally connected to the heat sink at a plurality of orientations of the interface means with respect to the heat sink. Each of the plurality of orientations of the interface means comprises a different emission direction of the light emitter. The effect of the measures according to the invention is that it enables to omit the need for a heat sink in the light source which enables to reduce the size of the light source while also allowing to reposition and redirect the light emitted from the illumination system.
