Abstract: The present invention provides a freely rotatable electrical conduction structure including at least two cylindrical electrical conduction portions, an insulated material portion and at least two electrical conduction terminals. The at least two cylindrical electrical conduction portions are arranged separately along an axis, wherein the inner surface of each cylindrical electrical conduction portion is welded with an end of a conducting wire. The insulated material portion is combined with the at least two cylindrical electrical conduction portions via injection molding to form a circular shaft assembly. The at least two electrical conduction terminals correspond to the at least two cylindrical electrical conduction portions respectively, and each electrical conduction terminal partially projects to form an arc contact portion configured to abut onto the outer peripheral surface of its corresponding cylindrical electrical conduction portion.

Abstract: The invention provides a power adapter assembly including an adapter body, a replaceable plug and a rotation locking collar. The adapter body comprises a cylindrical casing and a circular plug receiving base fixed on top of the cylindrical casing. The plug receiving base has a recess on the top thereof and a circular peripheral surface. The circular peripheral surface has a flange with an indentation on the top edge thereof, and a guiding groove formed from the indentation and extending downward to the bottom edge thereof. The replaceable plug is detachably mounted onto the plug receiving base. The rotation locking collar is detachably sleeved onto the plug receiving base and the support base, wherein the locking collar has a tab member on the inner top edge thereof adapted to enter the guiding groove and said one end of the elongated engagement groove.

Abstract: The invention provides a power adapter assembly including an adapter body, a replaceable plug and a rotation locking collar. The adapter body comprises a cylindrical casing and a circular plug receiving base fixed on top of the cylindrical casing. The plug receiving base has a recess on the top thereof and a circular peripheral surface, wherein the recess has an engagement block on the side wall thereof. The circular peripheral surface has a flange with an indentation on the top edge thereof, and a guiding groove formed from the indentation and extending downward to the bottom edge thereof. The replaceable plug is detachably mounted onto the plug receiving base and comprises a cylindrical support base comprising an upper portion and a lower portion sized to fit into the recess of the plug receiving base. The upper portion has an elongated engagement groove along its peripheral surface with one end extending to the bottom edge thereof and alignable with the guiding groove.

Abstract: The invention provides a power adapter combination including an adapter body and an adapter plug. The adapter body comprises a first casing having an inner space and a receiving recess structure with one side opened through the inner space, a circuit board disposed in the inner space, and a pair of connection terminals electrically connected with the circuit board and partially extending into the receiving recess structure. The adapter plug is detachably engaged into the receiving recess structure and comprises a second casing having a pair of slots thereon and a rear wall having a pair of holes, a bottom plate adapted to be assembled with the second casing, a pair of contact pins of which each has one pivoted end, is placed in one of the slots and is enabled to extend out of said one slot by rotation, and a pair of electrode structures mounted on the bottom plate and electrically connected with the contact pins, respectively.

Abstract: The invention provides a charger and adapter plug assembly including a first adapter plug, a second adapter plug, a third adapter plug and a charger. The first adapter plug has a set of AU standard pins and a first storage cavity with a first socket therein. The charger has two flat straight pins on one end and a USB port on the other end. The charger is detachably stored into the first storage cavity, so as to make the two flat straight pins electrically plugged into the first socket. The second adapter plug has a set of UK standard pins, a second storage cavity with an EU socket therein and an AU socket. The first adapter plug is detachably assembled to the second adapter plug, so as to make the AU standard pins electrically plugged into the AU socket. The third adapter plug has a set of EU pins and a second socket. The third adapter plug is detachably stored into the second storage cavity, so as to make the EU standard pins electrically plugged into the EU socket.

Abstract: A power socket device having switches is disclosed and has a housing, socket units, positioning members and conductive frames. The housing is formed with recesses communicated with an inner space thereof. The socket unit is installed in the recess, and can be slid forward and backward therein. The socket unit has a socket body and conductive terminals, each of which has a conductive block. The positioning member can be elastically received in the recess and stand upward. The conductive frames are engaged in the housing, and the conductive block can be in contact with or disconnected from the conductive frames. Thus, when the socket unit is slid forward or backward, a close circuit or an open circuit will be formed between the conductive block and the conductive frames, so that it is convenient to switch off the power without additionally adding redundant switches.

Abstract: A power socket device having switches is disclosed and has a housing, socket units, two conductive frames and switch units. The housing has bolt holes. Each of the socket units has a socket body and a pair of conductive terminals. The socket body is formed with a pair of terminal slots. The socket unit can be received in the housing, and slid upward and downward therein. The conductive terminals are inserted in the terminal slots, and selectively in contact with or disconnected from the conductive frames. The socket body has an engagement hole. The switch unit is inserted into the bolt hole, and selectively abutted against the socket body or engaged in the engagement hole, so that the socket unit can be positioned on a predetermined position on a vertical direction. Thus, it is unnecessary to unplug a plug of an external appliance when switching on or off the power.

Abstract: A power socket device having a rotation-operated switch function is disclosed, and has a housing, a first conductive frame, a second conductive frame and a plurality of socket units. The housing has recesses, each of which is installed with a socket plate having terminal slots. The first and second conductive frames are mounted in the housing. The socket unit is rotatably installed in the recess and corresponding to the socket plate. The socket unit has a socket housing, an insulating body and terminals. Each of the terminals has one end passing through one of the terminal slots to be in contact with or separated from the first and second conductive frame. Thus, the socket units can be rotated to switch on or off without unplugging the power socket device, so that the operation of the power socket device is relatively simple and labor-saving.
