Abstract: An improved modularized socket structure comprises: a main socket module, first, second and third polar main jacks are formed on a main conductive component of the module; at least one expansion socket module, first, second and third polar expansion jacks are formed on an expansion conductive component of the module; a sub-socket module, first, second and third polar sub-jacks are formed on a sub-conductive component of the module; and an expansion conductive plate set comprising first, second and third conductive plates, the first conductive plate has first extension portions inserted into first polar main jack, first polar expansion jack and first polar sub-jack, the second conductive plate has second extension portions inserted into second polar main jack, second polar expansion jack and second polar sub-jack, and the third conductive plate has third extension portions inserted into third polar main jack, third polar expansion jack and third polar sub-jack.

Abstract: An improved structure of a universal socket with polarity correction comprising: a cover, a wedging body disposed under the cover, and a shell disposed under the wedging body. The cover is formed with first neutral, first live wire, second neutral, and second live wire electrode socket holes. The wedging body is formed with first neutral electrode, first live wire electrode, second neutral electrode, and second live wire electrode holding holes. Neutral and live wire electrode plate accommodating grooves, and an electrode plate assembly are disposed in the shell. The electrode plate assembly comprises a first neutral electrode plate and a second neutral electrode plate electrically connected to each other and disposed in the neutral electrode plate accommodating groove, and further comprises a first live wire electrode plate and a second live wire electrode plate electrically connected to each other and disposed in the live wire electrode plate accommodating groove.

Abstract: A universal adapter structure comprises a housing, a socket unit, a first plug unit and a second plug unit. The first and the second plug units have a rocking base, two plug terminals and a driving member, respectively. The rocking base is pivotally disposed on the housing, the two plug terminals are fixed on the rocking base, and the driving member is movably disposed on the housing. By pressing the driving member, the rocking base can be pivoted, thereby driving an outer end of the plug terminal to pivot toward a direction away from the housing.
