Abstract in the disclosure a retaining device (1) for stopping a relative movement between a rail member and a sliding rack (3) is provided, includes: a first member (11), having a first engagement portion; a second member (12), having a second engagement portion; and a handle member (13) pivotally mounted onto the first member (11) via a pivot (14). The second member (12) includes a stopping portion (121), and the handle member (13) includes a first contacting edge (131) and a second contacting edge (132) which are configured to selectively abut against the stopping portion by means of the pivotal movement of the handle member (13). A distance between the second contacting edge (132) and the pivot (14) is greater than a distance between the first contacting edge (131) and the pivot (14), such that a distance between the first and the second engagement portions when the second contacting edge (132) contacts the stopping portion (121) is greater than a distance between the first and the second engagement portions when the first contacting edge (131) contacts the stopping portion (121).

A modular furniture unit can be configured to provide power distribution in conjunction with other furniture features. Embodiments of furniture arrangements may utilize one or more modular furniture units to provide one or more of such features (e.g. storage, seating, privacy, work surface, lighting, etc.). In some embodiments, the modular furniture unit includes an elongated upper member having an upper slot that has a first end and a second end opposite its first end. At least one leg is attached to the first end and at least one leg is attached to the second end. The elongated upper member may have a channel through which power cabling passes and outlets that are connected to such cabling. Different elements can be connected to the upper member via the upper slot or a downward facing opening of the upper member and/or to the legs to provide different furniture arrangements.

A cut-in floor box assembly including a bracket assembly, an electrical box, a support plate, and a cover plate for rapidly installing a duplex receptacle flush with a floor. Floor preparation requires simple drilling of the floor and subfloor with hole saws. Two concentric cuts are made in the floor, a hole of a first diameter through the floor and a second, smaller diameter hole through the subfloor. A peripheral wall on the bracket assembly fits within the hole in the subfloor. A floor mounting arrangement on the bracket assembly enables clamping the bracket to the subfloor. A component attachment arrangement on the electrical box is adapted to accept recessed attachment of a duplex receptacle enabling flush mounting of the duplex receptacle with respect to the floor surface. Two removable outlet covers on the cover plate provide convenient access to the receptacles for plug-in of electrical cords.

An improved patch panel assembly includes a frame and faceplate that mate with a housing, and the housing defines a plurality of individual communication ports. The housing is mounted to the patch panel frame and includes jack openings that accommodate data jacks and circuit board openings that accommodate mating blades of circuit boards. The two sets of openings are separated on the housing by an intervening spacing and interposer terminal sets are provided to electrically interconnect the jacks with circuits on the circuit boards. The patch panel housings may be formed in discrete groupings so that, if desired, the patch panels may have ports that are grouped together by bandwidth, storage capability and the like. Inasmuch as the housings are mounted to the patch panel frames, the jacks and the circuit boards can be easily and individually replaced, repaired or upgraded with similar components without requiring disassembly of the patch panel.

A tamper resistant electrical receptacle comprises a housing including a cover having at least one plug outlet formed therethrough, the plug outlet configured to receive both line and neutral blades of an electrical plug. The electrical receptacle further comprises electrical contacts positioned within the housing below the at least one plug outlet, the electrical contacts being configured to be connect to AC power. A shutter disposed within the housing between the cover and the electrical contacts is slidable between a closed position blocking access to the electrical contacts through the plug outlet and an open position allowing access to the electrical contacts through the plug outlet, the shutter being biased toward the closed position. The shutter is configured to slide from the closed position to the open position only upon simultaneous insertion of both the line and neutral blades of the electrical plug in the plug outlet.

Embodiments of an electrical outlet of the present invention generally include one or more sockets which include, in addition to positive, negative, and optionally, grounding electrical connections, at least one coupling/communication component, wherein AC electrical current flows through the outlet only when a plug comprising a complementary coupling/communication component is engaged with the socket, whereby the proximity of the coupling/communication component and the complementary coupling/communication component actuates the outlet to provide electrical current therethrough. In one embodiment, in lieu of a complementary coupling/communication component, a wireless transmission device is used to send a signal to the coupling/communication component to actuate the outlet. In other embodiments, an electrical outlet of the present invention includes a mechanism for maintaining engagement between the outlet and a receptacle/plug that provides for safe disengagement when they are inadvertently separated. Embodiments of a method of using embodiments of apparatuses of the present invention are also provided.

The present disclosure provides an improved leakage protection socket with reverse connection protection function. The electromagnetic tripping mechanism comprises a trip coil, an iron core and a permanent magnet that fit with a return spring, the iron core has, in its front end, a boss to pull the lock for horizontal movement, the movable input contacts are clamped by a rib slot of an upper tripper that can moves upward and downward along with the reset button. There is also provided a reverse connection trip device, which has a slope that coordinates with the boss of the iron core, upon reverse connection, the trip coil generates a magnetic field in the same orientation with the permanent magnet.

An electrical receptacle including a body having a plurality of electrical connections, a device face connected to the body, and wherein the device face is movable with respect to the body from an electrically inactive position to an electrically active position. The electrical receptacle may further include at least one pair of electrical contacts which are in electrical continuity when the electrical receptacle is in an electrically active position.

An extendable hanger apparatus to which or through which an electrical feed can be connected includes a support base, the support base has a containing groove and at least one support posts. Locating devices and a fastening component are provided on the containing groove, the locating devices configured to fixing the support base on a fixed structure, and fastening components are installed at the two end portions of the support base. The fastening components are configured to enable chaining, and the support post has a support component, the support component is configured to connect with an object for hanging.

Receptacle assembly includes a receptacle cage having an interior cavity forming first and second module passages. The first and second module passages are configured to receive respective pluggable modules through first and second port openings, respectively, in a loading direction that is parallel to a Z-axis. The receptacle assembly also includes a cage cover positioned at the front end between the first and second port openings. The cage cover includes first and second module fingers. The cage cover also including a ground tab that engages an inner surface of the receptacle cage. The first and second module fingers extend lengthwise in the loading direction. The ground tab extends lengthwise along a Y-axis that is perpendicular to the Z-axis.
