A charging system for installation into a block wall includes a docking unit, a cover unit and a charging unit. The docking unit includes a docking unit hollow body with an open front face, and a back plate closing the rear face and an electrical connector positioned within the docking unit hollow body. The cover unit includes a cover unit hollow body for insertion into the docking unit hollow body. The charging unit has a charging unit hollow body for insertion into the docking unit hollow body; and a charger module is located in the charger housing and the charging module includes contacts for connecting to the docking unit electrical connector, and a cable connector for connecting a charging cable. A method of installing the charging system in a block wall, comprises constructing the wall; installing the docking unit; attaching a cover unit the docking unit; and subsequently removing the cover unit from the docking unit and attaching a charging unit to the docking unit so that the charger module contacts engage the contacts on the docking unit electrical connector.

Disclosed are embodiments of a round floor grommet and a rectangular floor grommet. These floor grommets can be constructed in any desired shape other than round or rectangular. Frame portions that hold foam pieces are joined together to form a primary slit in the floor grommet. Cross slits can also be formed in the foam material. The foam is a semi-closed cell foam that is constructed from PVC and nitrile butadiene rubber which has superior sealing effects since the foam can conform around objects passing through the slits in the floor grommet and seal any flow of air through the slits.

A floor box for housing electrical components includes a bottom and a plurality of walls extending from the bottom to at least partially define an interior and to at least partially define a central opening accessible to a user. A top plate having an inner portion at least partially defining a first wiring compartment facing the central opening and a second wiring compartment facing the central opening is connected to at least one of the plurality of walls.

An apparatus provides temporary electrical connections to electrically powered devices. Exemplary arrangements include a base housing (01) that includes a socket (02) therein. Such a socket releasably engages electrical plugs to deliver household current, or may include USB ports or other types of sockets that releasably engage electrical connectors. A housing top cover (10) includes a socket access opening (11) that is in corresponding aligned relation with the socket. A rotatable plate (30) is positioned in underlying relation of the housing top cover and is rotatable in operative supported connection with the base housing. The rotatable plate includes at least one plate opening. The plate is selectively rotatable responsive to manual actuation of a button, between a socket blocked position in which an outer face of the plate blocks access through the socket access opening, and a socket access position in which the plate opening is in corresponding aligned relation with each of the socket and the socket access opening.

There is provided a utility junction box including a first housing portion with three sidewalls, a top sidewall, a rear access opening with a removable access cover, and an open bottom opening into an interior volume for receiving at least one line from a first location, and a second housing portion forming a weather guard extending cantilever style from the top sidewall and the three sidewalls including a sloping front face, a front wall, and a lower sidewall formed with a plurality of openings facing downwards, wherein each opening formed in the lower sidewall of the weather guard is configured to allow at least one utility line to pass from within the interior volume of the housing through the opening and direct the utility line through the opening formed in the lower sidewall of the weather guard to a second location exterior to the utility junction box.

A floor system uses interlocking elements to form a surface raised above a floor surface for the distribution of electrical power and data throughout the floor of a building. The base units of the interlocking elements define channels which receive cables for data and power transmission. Channel and corner covers overlie the channels and interlock with the base units to form the raised surface. Fused electrical feed modules within channels provide electrical power to bus bars which distribute the power to fused terminal boxes and radio frequency sensors and beacons mounted in the base units.

A power cord includes at least one electrically insulated wire, including a wire conductor disposed within an insulated sleeve, and a connection terminal. The connection terminal includes a crimp portion crimped and soldered to the wire conductor at at least one end of the at least one insulated wire. The power cord further includes a heat shrink sleeve covering the crimp portion of the connection terminal and a portion of the insulated sleeve of the at least one electrically insulated wire, and an overmold molded around at least a portion of the heat shrink sleeve.

A floor electrical outlet cover may be disposed over and coupled to a floor electrical outlet, the floor electrical outlet cover comprising a first color and further comprising at least one opening aligned with the floor electrical outlet, and at least one flap coupled to the floor electrical outlet cover, the flap configured to move from a closed position that restricts access to the floor electrical outlet to an open position that provides access to the floor electrical outlet. A colored electrical plate cover may comprise a second color different from the first color and a structural element coupled to the floor electrical outlet cover. The colored electrical plate cover may further comprise at least one opening aligned with the at least one opening in the floor electrical outlet cover. At least one colored flap cover may be coupled to the flap.

An electrical power and/or electronic data unit is mountable in a floor, and is fitted with an upper bezel that is openable and closable to provide selective access to an interior of the unit, which is optionally fitted with one or more electrical power or data outlets. A lower insert including an intumescent block is supported below an upper housing, and is angularly adjustable relative to the upper housing. One or more bores or openings formed in the lower insert allow the passage of cords into a pass-through opening in the upper housing, and out through an upper bezel cover.
