A mounting adaptor for an electric light fixture to be mounted on a surface. The mounting adaptor comprising: a base and a joining member each having an interfacing face and an electrical interface, one of the base and the joining member comprising on its interfacing face a groove, the other one of the base and the joining member comprising on its interfacing face a lip adapted to cooperate with the groove thereby providing a capability to assemble releasably the joining member with the base; a locking mechanism adapted to lock the base and the joining member in a mounted position relatively to each other; the base comprising a mounting element adapted to mount the base to the surface; and the joining member comprising a joint element adapted to mount the electric light fixture to the joining member.

A quick-connect plug and socket for mechanically and electrically attaching an electrical fixture. The plug has a spindle insertable into a bore of the socket to mechanically engage the plug and socket. An electrical connection forms between ring-shaped conductors on the plug that insert into ring-shaped openings in the socket to engage contacts within the socket. The plug body includes an extension extending from a side of the body to the spindle. The extension has a channel and slot, through which an electrical cord with wires inserts without threading the cord through the extension. The cord turns away from the extension to lie in a channel in the body and extend to a periphery of the body, to then connect to electrical terminals of the body. A removable cover covers the cord in the channel, the terminals, and the portion of wire that passes from the periphery to the terminals.

A mount plate includes a mount plate housing for coupling an audiovisual device with a battery. A power terminal in the mount plate housing provides electrical power to the audiovisual device. A hot wire connected with the power terminal extends from the mount plate housing. The hot wire is configured to connect with a corresponding hot wire of the audiovisual device. A ground wire extending from the mount plate housing is configured to be connected with a corresponding ground wire of the audiovisual device. A first insulation piercing interconnect is connected with the hot wire. The first insulation piercing interconnect is configured to connect the hot wire with the corresponding hot wire of the audiovisual device. A second insulation piercing interconnect is connected with the ground wire. The second insulation piercing interconnect is configured to connect the ground wire with the corresponding ground wire of the audiovisual device.

A modular socket (106, 306) for removably receiving a light-emitting diode (LED) driver (124, 324) and coupling the LED driver to LED(s) (104) is described herein and may include: a housing (108, 308); a power input interface (110, 310) to receive a supply voltage; a power output interface (120, 320) electrically coupled with the power input interface within the housing; an LED control input interface (128, 328) that is electrically coupled with one or more LEDs; and one or more mechanical engagement and locking structures (134, 334). Mechanical engagement of the mechanical engagement and locking structures with corresponding mechanical engagement and locking structures of the LED driver may simultaneously effect electrical coupling between: the power output interface and a power input interface (122, 322) of the LED driver, and the LED control input interface and an LED output interface (126, 326) of the LED driver.

A combination outlet connector is disclosed. The combination outlet connector includes an outlet core having three T-shaped apertures. The outlet core has a core outer surface to mate with a first connector type, such as a C14 connector, and electrical terminals are positioned in corresponding apertures. A removable adapter sleeve is positionable around the outlet core and has a sleeve outer surface to mate with a second connector type, such as a C20 connector. The adapter sleeve includes a sleeve aperture at least partially congruent with the core outer surface. The electrical terminals are configured to connect with mating terminals of the first and second connector types. A removable adapter shroud can be positioned around the outlet core. The shroud includes a shroud inner surface to receive the first connector type and a shroud flange having a shroud aperture at least partially congruent with the core outer surface.
