Abstract: A wireless transmission assembly includes a power cord and a communication outlet. The power cord includes a plurality of plug pins, an AC wire set, a transceiver, and a signal wire. Two opposite ends of the AC wire set are respectively connected to the plug pins and a mating electronic device. Two opposite ends of the signal wire are respectively connected to the transceiver and the mating electronic device. The communication outlet includes a plurality of socket pins, a communicator, and a wireless module. The socket pins are detachably connected to the plug pins. The communicator is arranged adjacent to the socket pins and is configured to cooperate with the transceiver in a wireless signal connection for getting information about the mating electronic device. The wireless module is electrically connected to the communicator, and is configured to transmit the information from the communicator to the external electronic device.

Abstract: A safety socket device includes a carrier, a first movable assembly and a second movable assembly. The carrier has a first plug hole and a second plug hole. The first movable assembly including a first moving element is transversely movably disposed in the carrier. The first moving element has two first guide portions, and the two first guide portions are moved for exposing the first plug hole from the first moving element by an external pushing force. The second movable assembly including a second moving element is longitudinally movably disposed in the carrier. The second moving element has a second guide portion, and the second guide portion is moved for exposing the second plug hole from the second moving element by the external pushing force.

Abstract: An integrated surge-absorbing device includes a surge-absorbing unit and a first external lead structure. The surge-absorbing unit includes a plurality of varistors stacked with together and a first metal lead, which is disposed between two of the neighboring varistors and has a first end protruding toward a first side edge of the varistors. A first end of the conductive rod of the first external lead structure is connecting to the first end of the first lead through a first low-melting-point metallic material. The first external lead structure applies a first resilient force to the first conductive rod.
