According to an embodiment, a connector device is connected to an electronic device. The connector device includes a signal processor, a switch, and a movable member. The signal processor processes a signal inputted from the electronic device or a signal outputted to the electronic device. The switch is ON when power supplied from the electronic device is used as a power supply for operating the signal processor. The movable member moves to a first position when the switch is ON and moves to a second position when the switch is OFF. The connector device is connectable to a power-supply-support electronic device and is not connectable to a power-supply-non-support electronic device when the movable member is at the first position. The connector device is connectable to the power-supply-support and power-supply-non-support electronic devices when the movable member is at the second 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 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 connector includes a first and second connector housings, a first and second terminals provided in the first and second connector housings, the second terminal including contact pieces with a gap therebetween, the gap being larger than a width dimension of the first terminal. The second connector housing includes pressing plate portions. The second terminal is to be accommodated between the pressing plate portions, the second terminal being displaceable between a first position and a second position, a part of the contact pieces extends beyond distal ends of the pressing plate portions when the second terminal is in the first position, the part of the contact pieces are completely retracted into a space between the pressing plate portions when the second terminal is in the second position. The contact pieces are to be pushed such that the contact pieces contact the terminal plate portions.

A charging device is provided. The charging device includes an output terminal unit connected to an input terminal unit of a battery pack. The output terminal unit includes a terminal body including an output terminal connected to the input terminal unit and a terminal cover which covers the output terminal before the input terminal unit of the battery pack is connected to the output terminal unit and through which the output terminal passes while the input terminal unit of the battery pack is connected to the output terminal unit.

A notification system including an electrical receptacle and a notification control unit. The electrical receptacle includes an outlet configured to receive an electrical device and a switch. The switch is configured to determine when the electrical device is received and output a signal when the electrical device is received. The notification control unit is configured to receive the signal, determine a state of the electrical receptacle based on the signal, and output the state of the electrical receptacle.

A first contact device is adapted to fasten to a second contact device of a contact system. The first contact device includes a first contact housing having a first contact receptacle, an actuating unit adapted to be swiveled between a first position and a second position different from the first position, and a contact element arranged in the first contact receptacle and electrically connected to an earthing line. The first contact housing is connected to the actuating unit. The contact element has a contact spring arranged in the first contact receptacle in the first position and, in the second position, the actuating unit adjoins the contact spring. The contact spring is swiveled at least partially out of the first contact receptacle and contacts a shielding contact of the second contact device.

An electric device includes a first receptacle to which a first plug is connected, a second receptacle to which a second plug is connected, and a cover member configured to open/close the second receptacle. In a state in which the first plug is connected to the first receptacle, opening of the cover member is restricted by interference between the first plug and the cover member. In a state in which the second plug is connected to the second receptacle, connection of the first plug to the first receptacle is restricted by interference between the first plug and the cover member.

An automobile connection cable is configured with a controller area network (CAN-bus) circuit design and provided with a protocol interface between the J533 connector and USB Type-C. The function of switching between different protocols is achieved through the configuration of the cable assembly, so that the driver-assistance system ensures a better adaptability to the VAG vehicle models of Volkswagen Corporation (VAG). When the vehicle is shut off, the circuit control board can also control the constant power supply system between the external device and the vehicle, thereby reducing power consumption.

An electronic apparatus connection cable includes: a first plug including a first power reception terminal; a first switch coupled to the first power reception terminal; a power transmission line coupled to the first switch; a second plug coupled to the power transmission line; and a first light emitting element coupled to the power transmission line. The distance between the first light emitting element and the second plug is smaller than a distance between the first emitting device and the first plug. When the first power reception terminal receives a first input voltage and the first switch is conducted, the first light emitting element emits light.
