In one embodiment, an electrical receptacle includes a housing, stationary electrical contacts for transferring power received at the electrical receptacle to a connected device, pin contacts for mating with socket contacts on a plug to create a first connection when the plug is moved along a longitudinal axis of the housing, and internal contacts extending from the pin contacts and located within the housing for mating with the stationary electrical contacts to create a second connection with movement of the plug different from movement for the first connection. An electrical arc created between one of the internal contacts and one of the stationary electrical contacts is contained within the housing. A method and adapter are also disclosed herein.

In a particular implementation, an electric power device includes a body, a receptacle configured to receive a plug, and a source connector configured to be coupled to a power source. The electric power device further includes a casing coupled to the body and movable with respect to the body between a first position in which the casing defines an enclosed chamber and access to the receptacle is inhibited and a second position in which the casing is configurable to enable access to the receptacle for receipt of the plug. A transition from the first position to the second position is configured to cause the receptacle to be electrically decoupled from the source connector when the casing is at the second position, and a transition from the second position to the first position is configured to cause the receptacle to be electrically coupled to the source connector when the casing is at the first position.

A male welding lead connector apparatus including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another. A method of locking a male welding lead connector to a female welding lead connector using a special male welding lead connector including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another.

A smart adapter includes an insulating body, a plug fastened to the insulating body, at least one socket, at least one seven-segment displayer, at least one button and a main control unit. The at least one socket is mounted in the insulating body and is exposed to a front surface of the insulating body. The at least one seven-segment displayer is mounted in the insulating body. The at least one button is mounted in the insulating body and is exposed to the insulating body. The main control unit is mounted in the insulating body and is connected with the at least one socket, the plug and the at least one seven-segment displayer. The main control unit includes a cloud unit and a central processing unit. The cloud unit is connected to the at least one button and the central processing unit.

A variety of active cover plate configurations with prongs configured to contact side screw terminals of electrical receptacles are described.

A seal cover (1) is provided for closing an opening portion (10) in a device in which a standby connector (11) is disposed. The standby connector (11) includes male terminals 11B for switching a state of an energizing circuit between a conductive state and a non-conductive state. Female terminals (23B), a shaft seal (25) and an O-ring (23D) are arranged in such a positional relationship that a time point when the shaft seal (25) is compressed maximally, a time point when the O-ring (23D) is compressed maximally and a time point when the female terminals (23B) are resiliently deformed maximally do not overlap with each other when the seal cover (1) is mounted on the opening portion (10).

A power circuit shut off device includes a housing and a switch portion provided in the housing, and an operating member configured to turn on or turns off the switch portion. The switch portion includes a pair of terminals arranged along a bottom face of the housing, an electric conductive member having contact point portions and that is elastically urged toward the pair of terminals, and an insulating movable member configured to move along a direction in which the pair of terminals are arranged. The pair of terminals are brought into electric conductive to each other when the pair of terminals contact the contact point portions respectively. The insulating movable member is moved between a shut-off position and a conductive position by an operation on the operating member.

A charging connector for providing power to a vehicle from a power source includes a connector body, a first charging portion, a second charging portion, and an actuator. The first charging portion is for charging the vehicle according to a first electric charge protocol and is movable between a first retracted state and a first extended state relative to the connector body. The second charging portion is for charging the vehicle according to a second electric charge protocol and is movable between a second retracted state and a second extended state relative to the connector body. The actuator is configured to selectively move the first charging portion between the first retracted state and the first extended state relative to the connector body, and the second charging portion between the second retracted state and the second extended state relative to the connector body.

The present invention discloses a connector and a connector assembly. The connector comprises a housing, a connection assembly, a safety cover and a high-voltage interlock. During mating the connector with the mating connector, when the connection assembly is not fastened, the connection assembly is in a position of interference with the safety cover to prevent the safety cover from being moved from an initial position to a safety position. The safety cover and the high-voltage interlock are slidably connected. When the safety cover is moved to the initial position, the high-voltage interlock is moved to a disconnected position, and when the safety cover is moved to the safety position, the high-voltage interlock is moved to a connected position. The high-voltage interlock is separated from the mating high-voltage interlock before the terminal is electrically connected with the mating terminal, improving use safety of the connector.
