An electrical connector arrangement includes a storage device coupled to a connector housing. The storage device is configured to store physical layer information pertaining to the electrical connector arrangement. The storage device also has contacts that enable the physical layer information to be read from the storage device by a media reading interface. A connector assembly includes at least one receptacle assembly; a printed circuit board; and a media reading interface.

A combination outlet assembly includes a single piece integrally formed housing having first and second outlet cores respectively having a similar outer shape and profile but differently shaped sets of three terminal apertures, and three terminals associated with each respective set of three terminal apertures in the first outlet core and the second outlet core. The first outlet core and the second outlet core may be interchangeably used with power cord plug connectors of different types. Power cord latching features are also described. Power distribution units may include a number of combination outlet assemblies ganged together.

A switched power receptacle that can be programmed to provide power for a user-selected duration in a user-selected cycle. The invention can be plugged into a conventional receptacle, extension cord, or other source of power. One or more user inputs and displays are provided so that the user can program the cycle for switching on the power (once every 2 days, once every 7 days, etc.). One or more user inputs are provided so that the user can select the duration of activation for each cycle (1 hour, 3 hours, etc.). Status indicators are preferably provided so that the user can easily monitor the operation of the device.

An electrical outlet for a recreational vehicle includes a high voltage AC electrical power receptacle and a low voltage DC electrical power receptacle that is powered independently of the high voltage AC receptacle so that the DC receptacle can remain energized when the AC receptacle is disconnected from an AC power supply. The DC and AC receptacles, located at the same electrical outlet, are wired separately to different power sources. This allows the recreational vehicle's electrical storage batteries to continue energizing the DC receptacle, at the same outlet as the AC receptacle, even when it is not possible or desirable to energize the AC receptacle. Therefore, limited functionality can be maintained at the outlet even when no AC mains, onboard generator, or AC-to-DC inverter is connected or in operation.

An electric apparatus including a connector holding six connecting terminals is provided. Three one-side connecting terminals held by the connector are arranged side by side in a row substantially directly below conductive terminals of three phases of one DC-AC converter. Three another-side connecting terminals held by the connector are arranged side by side in a row at positions offset to a side away from the one-side connecting terminals in an axial direction. Upper-end side connecting parts of the three one-side connecting terminals are set to be lower than upper-end side connecting parts of the three another-side connecting terminals, and are connected to the corresponding conductive terminals above via busbars extending in an up-down direction. The upper end-side connecting parts of the three another-side connecting terminals are connected to corresponding conductive terminals via busbars extending along an arrangement direction of the conductive terminals.

A multi-socket panel device with an anti-crosstalk structure, wherein a plurality of through holes are formed on the circuit board. The through holes are arranged in two rows extending from one side of the circuit board to another side of the circuit board. Two electrical connectors disposed on the circuit board are arranged near two opposite sides of the rows of the through holes. The electromagnetic wave propagating in the circuit board are reflected or refracted by the through holes due to travel in different media, whereby the crosstalk caused by the electromagnetic wave is avoided when signals of high frequency are transmitted in two electrical connectors.

A modular RF apparatus includes an RF portal and an RF expansion module configured to be coupled with the RF portal. The modular RF apparatus is configured to expand the number of outputs of the RF portal by adding the RF expansion module in a manner that minimizes an increase in the spatial footprint of the modular RF apparatus while allowing easy access to all ports of the modular RF apparatus. The RF portal and the RF expansion module are configured to interlock to create an integrated functional block. The modular RF apparatus are configured to permit upgrading of the RF portal by adding the RF expansion module without disrupting existing connections to the RF portal.

An apparatus connectable to a streetlight luminaire includes a housing, an electrical connector, power conversion circuitry, and an output power interface. The housing has a top surface, a bottom surface, and at least one sidewall interconnecting the top and bottom surfaces. The electrical connector is integrated with the bottom surface of the housing and electromechanically connectable to a top-side electrical connector of the streetlight luminaire. The power conversion circuitry is operable to receive an input alternating current (AC) signal from the electrical connector and produce at least one output AC signal, wherein an average voltage of each output AC signal is less than an average voltage of the input AC signal. The output power interface is electrically coupled to the power conversion circuitry and integrated with the sidewall(s) of the housing. The output power interface is arranged to provide the output AC signal(s) for use external to the housing.

This multi-couplings plate (P1) includes a locking device comprising a frame (14) fixed on the plate (P1), locking members and a drive mechanism, comprising a rotary element (18) rotatable in the frame (14), a sliding element translatable relative to the frame (14) and which cooperates with the locking members. The locking device also comprises several ratchet notches (301-309) secured to an element (18) of the drive mechanism (16) and juxtaposed in the movement direction relative to the frame (14) of the element (18) of the drive mechanism, the ratchet notches (301-309) comprising a final notch (309) and at least one intermediate notch (303-308), and a pawl movable in a housing (326) of the frame (14) and pushed back by a spring (28) toward one of the ratchet notches (301-309). When the pawl cooperates with the intermediate notch (303-308), the pawl limits the movement of the sliding element toward its forward position to a position midway between the forward position and the withdrawn position, and in the coupled configuration, the pawl cooperates with the final notch (309) and keeps the sliding element in the withdrawn position.
