A locking power cord receptacle configured to receive an electric power cord plug that includes a ground pin comprises a base receptacle and a locking assembly. The base receptacle includes a first female connector, a second female connector, and a ground female connector positioned on an upper surface and arranged to receive the power cord plug. The base receptacle further includes a body cavity on the upper surface. The locking assembly has a locked state in which the locking assembly blocks access to the base receptacle and an unlocked state in which the power cord plug can be plugged in to the base receptacle. The locking assembly includes a locking cover and a locking component. The locking cover includes a disc and a sleeve coupled to the disc and the base receptacle. The locking component is retained in the body cavity and has a locked configuration and an unlocked configuration.

The present system generally relates to a tamper resistant cap that prevents unwanted access to a semi-tractor trailer's 7 ways connection. The system includes a controller that can be operated remotely to transmit signals to an actuator within the cap. The actuator operates a lock to secure the cap in the closed position and selectively unlock the lock to allow the cap to be opened.

A self-locking connector provides an electrical connection between sources, equipment, devices, and the like. The self-locking connector generally includes first and second connector components with first and second housings that include corresponding electrically conductive elements, first and second magnetic elements, and first and second lock elements. One housing includes stationary and movable housing components. The connector components are brought into a coupled state with the corresponding electrically conductive elements providing an electrical connection. As the connector components are brought into the coupled state, the movable housing component automatically moves and brings the locking elements into locked engagement. The magnetic elements urge the connector components in the coupled state and the locking elements in locked engagement. The movable housing component is manually moved to bring the lock components out of locked engagement and the connector components out of the coupled state to break the electrical connection.

A method and system for contraband detection is provided that allows for the determining whether devices are authorized to receive power from an outlet. A power adapter and/or an outlet authenticate a device when it is connected to the outlet through the power adapter. On the basis of this authentication, a determination is made whether the devices are to receive power from the outlet. If the device is authorized, the outlet is activated, transitioning from inactive state (where no power is relayed through the outlet) to an active state (where power is relayed through the outlet).

In one example, the connector includes a body portion configured to be connected to a cord and a connection portion engaged with the body portion and comprising a plurality of conductors. The connection portion includes a conductive shield electrically connected to a plurality of the conductors when the connection portion is not engaged with the article of merchandise, and the connection portion also includes at least one ground conductor that is not electrically connected to the remaining conductors and/or the conductive shield when the connection portion is not engaged with the article of merchandise. At least one of the conductors and/or the conductive shield is configured to cooperate with the ground conductor to define a sense loop when the connector is engaged with the article of merchandise, and interruption of the sense loop is indicative of a security event.

An appliance cord assembly may include a first cord portion including a plug at one end configured to be received by a wall outlet and a plug mount at the opposite end, a second cord portion including a captive end hardwired to an appliance and a free end connected to a panel mount, the panel mount being configured to connect with the plug mount of the first cord portion to create a conductive engagement with the plug mount, such that in the connected state, the plug mount and the panel mount define a key opening, and a service tool configured to be received by the key opening to disconnect the panel mount and plug mount.

A releasable power assembly prevents damage to plugs and receptacles connected to refrigerated shipping containers (reefers). Reefers are temporarily stored in shipping port reefer scaffolds and then loaded onto or unloaded off of ground transportation or freighters. However, errors in port command and control systems may result in the failure to unplug reefers prior to loading or unloading. Conventional reefer power plugs and receptacles are twist-locked together and damaged or destroyed if not manually disconnected prior to reefer movement. An advantageous releasable power assembly automatically unlatches before reaching a breaking point for failure to disconnect plug and receptacle.

An electronically lockable, electrical plug configured to communicate power and data signals to mobile electronic devices (MED) includes a male electrical plug body insertable into a female electrical socket of the MED and plurality of electrical contacts defined in the male electrical plug for communicating the power and data signals to and from the MED, via corresponding electrical contacts associated with an MED electrical socket. The MED electrical socket is shaped and sized to physically receive and support therein said male electrical plug body. Plug locking elements are formed in the male plug body are so formed as to be lockable to or with corresponding, complementary socket locking elements of the MED, so that upon insertion of the male plug body into the MED socket the electrical plug is locked with the MED An associated, electronically operable locking mechanism is operable to mechanically disengage the plug locking elements from the socket locking elements to thereby enable the electrical plug to be released from the MED and an electrical cable is coupled to the male plug body for electrically conducting the signals.

A method for communicating between an electric vehicle and a charging station for electrically charging at least one energy storage device of the electric vehicle. The electric vehicle is connected to the charging station during the charging process by a lockable mechanical coupling between a terminal of charging cable connected to the vehicle and a terminal of the charging station. Charging current is fed from the charging station through the charging cable. Information is transferred in the course of the charging process based on a communication between the electric vehicle and the charging station. The information includes a signal transmitted from the electric vehicle to the charging station for locking and/or unlocking the mechanical coupling. The signal triggers the locking and/or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal at the charging station.
