A track adapter has a mounting seat, an electrical supply column, an adjustment conductive portion, and an adjustment knob, and a drive mechanism. As to the track adapter and the driving power supply with the track adapter and the track light, the lamp holder of the track lamp can wrap the whole track, which is neat and beautiful, and solve the problem of difficult phase adjustment of adaptor in the prior art at the same time. The phase adjustment knob is shrunk and put on the top of the adaptor, which solves the adjustment problem and adapts to more occasions, so that the structural design of the track lamp is more flexible.

A power-inlet plug has an installation seat, an elastic electrical conductive member and an external connector, the elastic electrical conductive member having a fixing portion and an elastic portion electrically connected to the fixing portion, the installation seat is provided with an installation cavity that accommodates the fixing portion and the external connector and a locking mechanism for detachable fix of the installation seat, the installation cavity is provided with an hole providing for the elastic portion extending out, and the elastic portion is provided with a retractable electrical contact. By setting the stop block, the permanent deformation and collapse of the shrapnel can be effectively prevented, and the problems of poor contact and contact failure can be solved. The locking part drives down the locking tongue and the power supply track extrusion locking structure design, effectively prevents the power-inlet plug from falling off.

A floor-mounted track for mechanical and electrical engagement of a removable electrical power outlet module includes a bottom ran, a first rail positioned parallel the bottom rail, a first electrode engaged with the first rail and extending along at least a portion of a length of the first rail, a second rail positioned parallel the bottom rail and spaced a distance from the first rail to define a slot between a slot side of the first rail and a slot side of the second rail, a second electrode engaged with the second rail and extending along at least a portion of a length of the second rail, a first wall connecting a first side of the bottom rail to a connected side of the first rail opposite the slot side of the first rail, and a second connecting a second side of the bottom rail to a connected side of the second rail opposite the slot side of the second rail.

An electrical connector includes a plurality of sheet terminals each having a main body and at least a pair of cantilevers. Each pair of the cantilevers extends from at least one of a first side and an opposite second side of the main body and has a pair of contact portions protruding toward each other inside a pair of free ends of the pair of cantilevers. The plurality of sheet terminals are assembled together in a stacked manner and a receiving chamber with an insertion opening is formed between the pair of cantilevers of the plurality of sheet terminals.

The present disclosure discloses a magnetically-adsorbed conductive track, a magnetically-adsorbed conductive track system and an electrical system in the field of lighting technology. The electrical system includes: at least two magnetically-adsorbed conductive tracks, at least one electrical apparatus and at least one adapter; the adapter cascades at least two magnetically-adsorbed conductive tracks. The magnetically-adsorbed conductive track includes: a main body portion including an adsorbing wall and a mounting wall; and an insulating portion and a magnetic element arranged in the main body portion; the insulating portion includes: a second space in communication with the adsorbing wall, and a first space which accommodates a conductive portion and is in communication with the second space; an elastic conductive terminal of the electrical apparatus and a collocating portion are jointly collocated into the second space of the magnetically-adsorbed conductive track.

An apparatus provides power for computer devices, such as servers, facilitating their testing outside of the typical server rack. A platform of supports the computer device while providing for a power supply unit beneath the platform to be connected to the device. The location of the power supply beneath the platform decreases the combined footprint of the apparatus and device under test. The power supply unit may be configured to connect to standard voltages, allowing the computer device to be tested where connection to rack-level voltage is not convenient.

A bridge joint assembly for use with a busway system includes a plurality of insulator assemblies, a bolt holding the insulator assemblies in a stack, a housing enclosing the insulator assemblies, a seal surrounding the bolt, and a bolt access system extending from a wall of the housing to the seal. The bolt includes a bolt head protruding from the stack. The bolt access system defines a bolt access passageway that provides access to the bolt head from outside the housing.

In accordance with various embodiments, lighting systems features multiple inter-connectable light panels each having multiple light-emitting elements thereon. One or more of the light panels features one or more connectors, and associated conductors, for the transmission of power, communication signals, and/or control signals.

A utility conduit system includes a base having a bottom wall, a first side wall extending from the bottom wall, and a second side wall extending from the bottom wall at least partially defining a channel. Various components can be removably positioned in the base to customize the utility conduit system for a given location. Some components can include a universal mounting bracket, a by-pass unit, and a divider bracket.

A power supply rail includes a groove extending in a first direction in a base portion and having an opening on a one-end side in a second direction, a conductive portion provided at a bottom surface of the groove, and a first recess formed on a first side wall of the groove. A power supply terminal is attachable/detachable into/from the groove, and includes terminal portions formed on an other-end side in the second direction of a body portion, a lead-wire portion from the terminal portions and elastic portions provided on a first side surface of the body portion. The elastic portions are latched in contact with an inside of the first recess of the power supply rail, and the terminal portions contact with the conductive portion.
