A power adapter includes a housing, a holder, a moving part, and a prong. The housing defines an inner cavity and a through groove communicating with the inner cavity, and the holder is received in the inner cavity and provided with a boss fitting the through groove. The boss defines a receiving groove at a side away from the inner cavity. The moving part is movably connected to the holder and partially exposed to an outside of the housing. The prong is rotationally connected to the boss, and the prong is movable relative to the holder along with the moving part, so that the prong is flippable to extend out from or retract to the receiving groove.

An electrical connector can include a receptacle disposed in a housing. The housing can include a second end and an openable first end having at least two housing portions that are movable relative to each other between: an open position in which the receptacle is accessible by a plug through the housing portions; and a closed position in which the receptacle is not accessible by the plug through the housing portions. At least one of the housing portions can be biased toward the open position. The electrical connector can further include a grip coupled to the housing and movable relative to the housing between a first position that permits movement of the housing portions to the open position; and a second position in which the grip overlies the at least one biased-open housing portion such that the grip prevents movement of the housing portions to the open position.

An electrical connector system for assisting in coupling and unmating electrical connectors. The system generally includes an electromagnet to assist in mating and, alternatively, unmating or uncoupling a first electrical connector with a second electrical connector. The system may include a first electrical connector having a first plurality of contacts, an electromagnet on the first electrical connector adapted to produce a magnetic force, and an input device adapted to receive an input and to provide an output that causes an electrical current to be supplied to the electromagnet. When coupled, the first plurality of electrical contacts are conductively engaged with a second plurality of electrical contacts on the second electrical connector.

A power-circuit breaking device includes a receptacle and a plug. The receptacle includes a power terminal and a signal terminal. The plug includes a main terminal and a sub-terminal. The plug includes a plug housing, a lever which is attached to the plug housing, a lock slider which is attached to the plug housing, and a sub-connector which is supported by the lock slider. The plug housing holds the main terminal. The sub-connector holds the sub-terminal. When the lock slider slides, the sub-connector moves. When the lever is located at a closed position, the main terminal is connected to the power terminal. When the lock slider is located at a connected position, the sub-terminal is connected to the signal terminal.

A charging connector comprises a lock lever having a latch, a cooperation portion, a switch mechanism and a temporary maintenance mechanism. The latch is movable between an engageable position and a released potion via a predetermined position. The switch mechanism is located at an initial position when the latch is located at the engageable position. The switch mechanism includes a pressed portion. The temporary maintenance mechanism temporarily maintains the switch mechanism at the initial position when the latch is located between the engageable position and the predetermined position. When the latch is located between the predetermined position and the released position, the cooperation portion presses the pressed portion of the switch mechanism to move the switch mechanism from the initial position against the temporary maintenance mechanism and thereby changes a state of the switch body from the initial state to a released state.

A cable connector includes a slide coupled to a spring to bias the slide from a retracted position to an extended position and at least one latch coupled to the slide. The slide, when in the extended position, is configured to rotate the at least one latch to secure the at least one latch, and when in the retracted position, is configured to rotate the at least one latch in an opposite direction to release the at least one latch. The slide is configured to engage a contact switch when securing the at least one latch.

A position assurance apparatus includes a first connecting portion, and a second connecting portion configured to be electrically connected to the first connecting portion. The first connecting portion and the second connecting portion are configured to be electrically connected to a signal circuit through a first connector, so that the signal circuit is turned on in response to the first connector and a second connector being plugged into place.

An external power supply connector attached to a vehicle-side connecting portion and control unit controlling the supply power to the vehicle-side connecting portion, supplying power from the vehicle to outside. The external power supply connector includes a body including an external connecting portion to an electric plug supplying power to a connected external device; a restricting member enables switching between restricting state wherein the electric plug is restricted from being attached and detached to and from the external connecting portion, and allowing state enabling the electric plug to attach and detach to and from the external connecting portion. A signal outputting portion outputs a signal to the control unit and detecting portion. The detecting portion detects the restricting state and allowing state of the restricting member. In allowing state, the signal outputting portion outputs a prohibiting signal from being supplied to the external power supply connector to the control unit.

A power distribution system includes a plurality of bus plugs. Each of a respective bus plug of the plurality of bus plugs includes an electrical switch configured to selectively control a corresponding energization of the respective bus plug and an actuator operable to control a corresponding electrical switch. The system includes a remote application having commands defining the energization of at least one of the plurality of bus plugs. The system further includes a communication module configured to communicate the commands from the remote application to the at least one of the plurality of bus plugs. The commands cause the corresponding actuator to control the corresponding electrical switch. Methods of controlling energization of a bus plug with a remote application and communication module configured to operate an actuator are also provided.

A connector configured to be fitted with a mating connector includes a main housing, a sub-housing supported on the main housing to be slidable in a fitting direction with respect to the main housing in which the connector is fitted with the mating connector, and an operating member pivotably and slidably supported on the main housing. The main housing moves closer to the mating connector when the operating member is pivoted from a first posture to a second posture. The sub-housing moves in the fitting direction when the operating member slides from the second posture in a direction different from the fitting direction. The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.
