A connector, a bayonet-style connector, and methods for using the connector or bayonet-style connector are provided. At least one connector includes a receiver having an inner volume to receive a connector, and having a pawl; and a pushbutton or actuator that operates to move or unlock the pawl so that a user can insert and lock and/or unlock and remove the connector using only a single hand of the user. At least one bayonet-style connector includes a connector portion having an opening; a receptacle portion that operates to slidingly accept the connector portion and that has a pawl that operates to engage with the opening to lock the connector portion in place; and an actuator that operates to impart force on the pawl to unlock the connector portion so that a user can remove the connector portion using only one hand of the user.

A card connector includes: a casing including a shell having a slide hole and a slit into which a card is inserted; an ejector, provided in the casing, configured to move together with the card that is inserted into the casing; a rotating member, supported by the ejector, configured to rotate when the ejector moves; and a projection that is provided at a first end of the rotating member opposite to a second end of the rotating member with respect to an axis of a rotation of the rotating member, comes into contact with the card and slides along the slide hole when the ejector moves.

The present disclosure discloses an electric shock-proof plug that comprises an insulating sleeve, a plug body, and a reset member. The plug body is movably disposed in the insulating sleeve. An inner wall of the insulating sleeve comprises a guiding groove, and an outer wall of the plug body comprises a sliding member movably coupled to the guiding groove. The sliding member moves in the guiding groove to drive the plug body to move between a high position and a low position. When the plug body moves to the low position, a connector of the plug body is exposed out of the insulating sleeve, and the reset member generates an elastic resetting force. When the plug body moves to the high position, the connector is retracted back into the insulating sleeve. A user will be prevented from getting an electric shock when unplugging the electric shock-proof plug.

A connector is provided with a first housing, a second housing connectable to and separable from the first housing, a spring member, a first pressing portion and a second pressing portion arranged at positions to accumulate a resilient force in the spring member according to connection of the first housing and the second housing, a first pressure receiving portion and a second pressure receiving portion arranged to receive a resilient restoring force in a direction to connect the first housing and the second housing from the spring member having the resilient force accumulated therein, and a first holding portion and a second holding portion for holding the spring member in a resilient force accumulating state of accumulating the resilient force by the first pressing portion and the second pressing portion only from start to a halfway state of the connection of the first housing and the second housing.

The present disclosure provides a charging receptacle and a charging plug, which cooperate with each other and comprise a receptacle ejection device and a plug ejection device respectively for automatically separating the charging receptacle from the charging plug after charging of the apparatus to be charged is completed. The present disclosure further provides a charging system comprising the charging receptacle and the charging plug as described above.

A USB wireless dongle includes a main body and an adaptor, the adaptor includes a first mounting enclosure and a first USB plug. The first mounting enclosure defines a receiving cavity for a circuit board. An end of the first mounting enclosure adjacent to the first USB plug defines a through hole. The first USB plug includes a button and a contacting board. The contacting board is electrically connected to the circuit board. An elastic piece abuts the button, the button being fitted in the through hole. The button can be pressed to deform the elastic piece to enable the button to separate from the through hole and thereby the first USB plug can be disassembled from the first mounting enclosure to be replaced with another USB plug.
