A sliding power contact and method includes a mobile load device connector and a socket. The mobile load device connector includes a non-current power pin having a first length, a current power pin having a second length less than the first length, a neutral pin, and a ground pin. The socket includes a non-current power contact configured to electrically couple with the non-current power pin, a current power contact configured to electrically couple with the current power pin, a neutral contact configured to electrically couple with the neutral pin, and a ground pin configured to electrically couple with the ground pin. An arc suppressor is directly coupled to at least one of the non-current power pin and the non-current power contact, wherein the arc suppressor, the non-current power pin and the non-current power contact form a current path between the current power pin and the current power contact.

A receptacle connector includes a housing defining a base and a mating tongue forwardly extending therefrom, a first row of contacts disposed in the housing with contacting sections and surface mount type tail sections for mounting on a PCB, a second row of contacts disposed in the housing with contacting sections and through hole type tail sections for mounting in the PCB; a metallic shield including a capsular segment surrounding the mating tongue to define a mating cavity and a rear wall covering a rear face of the base to surrounding the surface mount type tail sections and a lower bracket attached to the metallic shielding. The lower bracket is located upon a bottom side of the shield and includes a bottom wall, two sidewalls and a rear wall commonly surrounding the through hole type tail sections.

An apparatus includes an electrical plug insertable into a power outlet of a receptacle, where the electrical plug includes a ground pin with an indent. The apparatus further includes a retention mechanism enclosed by the receptacle includes a rod configured to interact with the indent of the ground pin, where the rod seated within the indent of the ground pin prevents a removal of the electrical plug from the power outlet.

Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

An electrical connector includes: an insulative housing comprising a base portion and a tongue portion extending forwardly from the base portion; a number of upper and low terminals mounted in the insulative housing and exposed to an upper surface and a lower surface of the tongue portion, the upper terminals and the lower terminals being equal in number, both the upper terminals and the lower terminals comprising five intermediate terminals arranged centrally in succession and one grounding terminal spaced from the five intermediate terminals by two terminal positions, each of the five intermediate terminals having a reserved space for not arranging a terminal, the five intermediate terminals comprising an auxiliary terminal; and a shielding plate disposed between the upper terminals and the lower terminals.

Systems, methods, and devices are provided in which cord storage cartridges are removably connected to a power distribution unit (PDU). The cord storage cartridge may include a cartridge housing having at least one aperture, a PDU interface associated with the cartridge housing and configured to removably connect the cord storage device to a mateable interface of the PDU, and a power output cord having a proximal end in electrical communication with the PDU interface and a distal end coupled with an output connector that is configured to connect to electronic equipment. The power output cord may be stowed at least partially within the cartridge housing in a retracted state and moveable through the at least one aperture to an extended state at least partially external to the cartridge housing.

A lighting system is incorporated into the ends of the electrical power cords to provide light when working in dark environments. The lighting source is preferably battery-operated, thus allowing the user to find power receptacles when in these dark environments. Additionally, a second power source is included in the plug receptacle end, which can be battery-powered or can be powered by electrical power carried within the power lines. The ends of the extension cord include supports.
