A connector includes: a first connector including a first main terminal; a second connector including a second main terminal and a boss having a protruding shape; and a fitting detection circuit configured to detect fitting of the first connector and the second connector. The first connector further includes a rotatable lever used for a fitting operation to the second connector and a fitting disengagement operation from the second connector. The lever includes a lock configured to lock, when the lock contacts the boss in the fitting disengagement operation, a rotation of the lever in a state where the fitting is not detected by the fitting detection circuit and also in a state where the first main terminal and the second main terminal are connected.

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes a plurality of conductors. The second electrical contact device includes a first portion, a second portion movable in a rotational and translational manner relative to the first portion, and an actuator movable between a first position and a second position. The first portion includes first electrical contacts, and the second portion includes electrical sockets. Each socket receives an associated conductor and includes a second electrical contact aligned with an associated first electrical contact. The second portion is biased away from the first portion. When the actuator is in the first position, the actuator inhibits translational movement of the second portion toward the first portion. When the actuator is in the second position, the second portion is movable toward the first portion to permit the second electrical contacts to engage the first electrical contacts.

The present invention provides safety power outlets having the form and size to fit standard electrical boxes. The present invention includes one or more switched sockets which are generally switched on by movement from a first position to a second position. The described movement is prevented by one or more locks configured to be unlocked by complete insertion of a plug's power blades into the socket. In addition, blade locks are provided to prevent removal of the plug once the movement from the first position to the second position has begun. The movements described herein are both linear and rotary. Embodiments adapted for use with an extension cord socket are also presented.

The present application relates to the technical field of smart home, especially to an USB socket, a button controller and a smart home. The USB socket includes housing, a rubber core, and a set of terminals. The housing defines a cavity for fixing the rubber core. The set of terminals includes a first contact terminal and a plurality of second contact terminals, and the first contact terminal and each of the second contact terminals are arranged side by side. A front end of each of the second contact terminals is exposed on the glue core and located within the cavity. A front end of the first contact terminal is located below the front end of its adjacent second contact terminal, and thereby an elastic gape is formed there between, such that when a USB plug is plugged into the cavity, the front end of the first contact terminal is contacted with the front end of the second contact terminal pressed by the USB plug. The USB socket of the present application can enable the button controller to be in a zero standby state when being not in use, and thereby avoid power consumption loss.
