Abstract: The present invention provides a multinational adapter structure comprising a front cover, a main body, and aback cover. The front cover has a first through-hole and a second through-hole. The main body is provided with a press assembly, a first electrical connection assembly, and a second electrical connection assembly. At least one elastic member is provided between the press assembly and the main body. The first electrical connection assembly and the second electrical connection assembly respectively having a first conductive member and a second conductive member are disposed on the press assembly. The back cover is assembled on one side of the front cover, and the main body is enclosed by the back cover and the front cover. Through pushing the press assembly, the first electrical connection assembly or the second electrical connection assembly can be moved in a distance to accommodate with different national standards of various countries.

Abstract: The expandable power adaptor contains a first casing member, a second casing member, a circuit assembly, and at least a metallic connector. The first casing member has a first coupling element set. The second casing member has a second coupling element set. The first and second casing members are joined to form an enclosed accommodation space. The circuit assembly and the metallic connectors electrically connected to the circuit assembly are configured in the accommodation space. To assembly, the first lower piece and the second lower piece are joined to form a complete lower piece. Then the circuit assembly and the metallic connectors are configured on the complete lower piece, and the first and second upper pieces are vertically joined to the first and second lower pieces. Additional casing members can be integrated between the first and second casing members so as to achieve the desired number of outlets.

Abstract: A safety socket includes hot/neutral slots formed in a bottom of the safety socket, a movable shielding member arranged in the safety socket to correspond to the hot/neutral slots, and an elastic element having two ends respectively fixed to the movable shielding member and a top of the safety socket. With such an arrangement, when the hot/neutral slots simultaneously receive plug prongs to insert therein, the movable shielding member is caused to move toward the top of the safety socket and when the plug prongs are withdrawn, the movable shielding member is returned by elasticity of the elastic element to shield the hot/neutral slots. Through such an operation, the moving direction of the movable shielding member is changeable so that unnecessary space of the safety socket can be eliminate to overcome the problem that a conventional safety socket has a bulky size.

Abstract: A multi-functional polarity-correcting plugging-coupling switching device includes a rotary component, which is rotatable and has at least one inspection element that is electrically connected to a touch control resistor and a live connection of a power plug. With a user using a hand to touch the touch control resistor, a closed circuit is formed with the human body for identifying correct position of polarization of the power plug. Further, through rotation of the rotary component, correct polarization and voltage level can be selected. Further, a resistive indicator is provided for indicating correct connection of earth line.

Abstract: The electrical adaptor contains a casing having a receiving indentation. Two corresponding positioning notches are provided, respectively, along two opposing lateral side walls of the receiving indentation. Inside the receiving indentation, there are two prong holes, each having an electrical contact inside. A first ground piece is tightly embedded into a front notch along a front wall of the receiving indentation. An additional second ground piece is provided along a back wall of the receiving indentation, opposing the first ground piece. When a German- or French-style plug is plugged, its two positioning ribs on the lateral sides are received by the positioning notches, respectively, and its ground pieces in the front and back are received by the ground notches. In the mean time, its prongs are received by the prong holes and contacted by the electrical contacts, respectively.

Abstract: An electric connector equipped with multiple layers of safety structure includes an insulation case, an electric connection terminal set and a safety mechanism. The insulation case has a front panel with a plurality of slots. The safety mechanism has a safety gate set and a blocking plate latching element. The safety gate set is pushed by a plug and to open the slots to allow the plug to pass through and to establish electric connection with the electric connection terminal set. The blocking plate has a brake portion. The blocking plate latching element has a stirring portion exposed outside the surface of the insulation case and a stop portion corresponding to each blocking plate. The stop portion is movable with the stirring portion to the brake portion to stop the blocking plate from moving. Thereby the blocking plate latching element can control opening of the safety gate set.
