Other aspects of the busbar connector assembly and methods of connecting an electronic device to a busbar are further disclosed.

The present invention relates to an adapter (1) for connecting a light to a track having mains phases and comprising a housing (2), at least one spring-loaded connector (6.1) linked to the housing (2), and a cover (4) partially covering the housing (2) and having at least one opening (8.1). The cover (4) is displaceable so as to be placed selectively in one of: a position in which the at least one spring-loaded connector (6.1) extends at least partially through the at least one opening (8.1), a position in which the cover (4) covers the at least one spring-loaded connector (6.1).

A busway for power distribution to equipment positioned in information technology racks includes a plurality of locations in the busway suitably being configured to receive a plurality of detachably engageable taps. The busway, which are external to the information technology racks, includes a plurality of segments, each of which are detachably engaged with one another and including at least one of the plurality of locations. The busway provides power to the information technology racks by respective taps, where each of the taps includes a respective electrical sensor that senses at least one of a voltage level and a current level. Each of the electrical sensors providers an output signal to a computing device.

In various embodiments, a connector for lighting devices including an elongate planar support member having a front surface with electrically conductive lines and at least one electrically-powered light radiation source thereon, is provided. The connector includes a C-shaped body having a web portion and two side portions, said C-shaped body locatable astride said planar support member with said web portion facing said front surface, and electrical contact means extending from said web portion between said side portions configured to contact electrically conductive lines on said front surface of said planar support member.

In various representative aspects, an apparatus for securing solar panels to a rail support guide, while facilitating grounding by a common grounding wire. The apparatus is an electrically conductive lay-in-lug fastener, which facilitates multiple rows of solar panels to be electrically bonded to each other. The apparatus includes a lug member for securing the grounding wire. In doing so, the structure for securing the grounding wire is at an acute angle to the frame, enabling a wrench to be used even in space-challenged locations.

A low profile (1U) power distribution system includes a power shelf assembly having a first side and an opposing second side. First and second bus bars extend across the assembly and substantially in parallel with the first and second sides, the second bar positioned behind the first bar. One row of power supply pins extends from the bars to engage power supply units within the assembly. A first set of pins extends from the first bus, while a second set extends from the second bar and protruding through respective apertures in the first bar. An insulating material may be provided to electrically insulate power supply pins of the second bar from the first bar. The reduced height profile of the bars allows for cooling air to pass through the remaining >50% of the assembly, which may now desirably include additional electrical circuits within the cooling channel.

A locking mechanism is disclosed for being locked together with a structure to be engaged, the locking mechanism including: a driving member, which is capable of moving in a driving direction; a first driven member and a second driven member, both of which are disposed axially symmetrically with respect to the driving direction and are coupled with the driving member so as to be driven by the driving member to move toward or away from each other along a driven direction of each of the first driven member and the second driven member respectively, the driven direction of each of the first driven member and the second driven member being transverse or oblique to the driving direction; an actuating handle, which is coupled with the driving member to move the driving member in the driving direction.

A power connector includes an outer casing couplable to a chassis such that the outer casing is positioned between sides of the chassis. The power connector also includes a body movably coupled to the outer casing. The body is movable between a first position and a second position. The body extends beyond the outer casing when in the first position. The body positioned entirely within the outer casing when in the second position.

A power distribution system includes a plurality of wires extending between a first end and a second end. The wires extend continuously between the first and second ends. Each wire includes an electrical conductor and an insulation layer. The power distribution system further includes a receptacle selectively positionable at any position along a length of the wires. The power receptacle includes a housing defining at least one power outlet. A plurality of connection members is positioned within the housing. Each connection member includes a first end and a second end. The first end is configured to contact the electrical conductors within the insulation layers of the plurality of wires for electrically connecting the plurality of connection members to the plurality of wires. The second end is configured to electrically connect the plurality of connection members to the at least one power outlet.
