A power supply system includes a housing comprising internal power circuitry; a receptacle panel removably coupled to the housing; and a circuit interrupter, such as a circuit breaker or fused disconnect switch, held in the housing. The circuit breaker includes a switch handle that is externally accessible and configured to allow a user to translate the switch handle between OFF and ON positions, the OFF position associated with electrical isolation of the power receptacle panel from a power output path between the receptacle panel and the internal power circuitry. In the OFF position, even when the power supply system is in an ON state, the receptacle panel is in electric isolation from the internal power circuitry and de-energized to thereby allow a user to remove the receptacle panel to thereby allow a hot swap with another receptacle panel.

The present disclosure relates to a novel smart socket having a function of electric leakage protection. The novel smart socket includes an upper cover, a base and a middle-layer support, where a reset button is arranged on the upper cover; a tripping device is arranged on a circuit board and includes a tripper, a lock catch element and an electromagnetic assembly. The electromagnetic assembly includes a tripping iron core, a tripping spring and an accommodation frame, where an end of the tripping iron core is in linkage connection with the lock catch element; and one end of the lock catch element is in linkage connection with a linkage shaft and is located in the first cavity. The present disclosure simplifies an internal structure, and improves reliability of the novel smart socket having a function of electric leakage protection.

An electrical receptacle contains a plug outlet that has a pair of contacts for electrical connection to respective hot and neutral power lines. A controlled switch, such as a TRIAC, is connected in series relationship between the outlet contact and the hot power line. Sensors in the receptacle outputs signals to a processor having an output coupled to the control terminal of the controlled switch. The processor outputs an activation signal or a deactivation signal to the controlled switch in response to received sensor signals that are indicative of conditions relative to the first and second contacts.

An electrical outlet receptacle including a circuit board, a set of fixed contacts and a set of movable contacts, a solenoid, a carriage, a lifting shelf, a slide mechanism, a reset plunger, and an armature.

Plug connections and in particular plug connections for use in an industrial environment are presented. An attachment housing arrangement has an attachment housing for accommodating a hood of a plug connector with plug contacts and a mechanical locking arrangement for mechanically locking the hood on the attachment housing. Also presented is a method for unlocking a mechanical locking of a hood of a plug connector with plug contacts on an attachment housing of an attachment housing arrangement. The attachment housing arrangement is provided with a fixing arrangement for fixing the mechanical locking arrangement at least in a locking state, and with a control unit for controlling the fixing arrangement, the control unit being configured to control the fixing arrangement so as to release a fixing of the locking arrangement only when the plug contacts are free of current and free of voltage within predefined tolerances.

A circuit to protect an overvoltage in a universal serial bus (USB) device include an overvoltage protection (OVP) switch connected to a pin of a USB receptacle and a switch controller to turn off the OVP switch when an overvoltage is detected such that power between the pin and the USB device is interrupted. The switch controller supplies a control signal to the OVP switch such that the OVP switch has a first on-resistance when the USB device is operating in a normal mode and no overvoltage is detected, and has a second on-resistance, higher than the first on-resistance, when the USB device is operating in a low-power mode and no overvoltage is detected.

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.
