Abstract: A power socket includes a socket main body, a front cover and a safety gate mechanism. The front cover has two openings. The safety gate mechanism includes a casing and a safety gate. The casing located between the socket main body and the front cover has two inserted holes and a protrusion. The inserted holes are aligned with the openings. The safety gate slidably disposed at the casing is dislocated from the protrusion. When the safety gate is at a first position, the safety gate blocks the inserted holes, and two terminals of a plug push the safety gate through the two openings to make the safety gate slide to expose the inserted holes. When an object pushes the safety gate through one of the openings, the safety gate rotates to drive a part of the safety gate to be aligned with the protrusion to avoid exposing the inserted holes.

Abstract: A power supply device using electric power network connects to an external power source and an electronic device, and supplies an alternating current power from the external power source to the electronic device to be a direct current power for the electronic device. In this case, the power supply device using electric power network comprises an electric power connection unit connected with the external power source, a conversion unit connected with the electric power connection unit, and an output unit connected with the conversion unit and the electronic device. The electric power connection unit is used for acquiring the alternating current power from the external power source, and the alternating current power is converted into a direct current power by the conversion unit. Thereby, the direct current power required for the electronic device during the process of charging and supplying power is supplied.

Abstract: An electromagnetic shielding cover and a device having the same are introduced. The device comprises a casing and is coupled to a base having a printed circuit board on which an electronic component is mounted. The casing is defined with a receiving region. The electromagnetic shielding cover is disposed within the receiving region and coupled thereto. The electromagnetic shielding cover is marked with a plurality of peripheral folding lines. The electromagnetic shielding cover is folded along the peripheral folding lines by an angle to form a plurality of walls and a shielding space. Coupling the casing and the base together allows the electromagnetic shielding cover to shield an electronic component mounted on the circuit board and received in the shielding space, thereby shielding the electronic component from electromagnetic interference. The electronic component can be easily changed and tested during a rework process.
