Modularized socket structure

An improved modularized socket structure comprising:

• a main socket module, the main socket module having a main top cover, a main conductive component and a main bottom cover assembled with one another, a first polar main jack, a second polar main jack and a third polar main jack being formed on a bottom of the main conductive component;
• at least one expansion socket module, the expansion socket module having an expansion top cover, an expansion conductive component and an expansion bottom cover assembled with one another, a first polar expansion jack, a second polar expansion jack and a third polar expansion jack being formed on a bottom of the expansion conductive component;
• a sub-socket module, the sub-socket module having a sub-top cover, a sub-conductive component and a sub-bottom cover assembled with one another, a first polar sub-jack, a second polar sub-jack and a third polar sub jack being formed on a bottom of the sub-conductive component;
• and
• an expansion conductive plate set, the expansion conductive plate set comprising a first conductive plate, a second conductive plate and a third conductive plate, the first conductive plate being formed with a plurality of first extension portions respectively inserted into the first polar main jack, the first polar expansion jack and the first polar sub-jack, the second conductive plate being formed with a plurality of second extension portions respectively inserted into the second polar main jack, the second polar expansion jack and the second polar sub-jack, and the third conductive plate being formed with a plurality of third extension portions respectively inserted into the third polar main jack, the third polar expansion jack and the third polar sub-jack.
