Multifunctional connecting device

A multifunctional connecting device for USB 3.0 Type-A and USB Type-C connector interfaces, comprising:

• a first module including:
• a first insulating main body;
• and
• a first terminal set disposed in the first insulating main body and having a plurality of first terminals and a plurality of second terminals, each of the first terminals formed with a first contact portion and a first conductive portion, each of the second terminals formed with a second contact portion and a second conductive portion;
• and
• a second module including:
• a second insulating main body;
• and
• a second terminal set disposed in the second insulating main body and having a plurality of third terminals and a plurality of fourth terminals, each of the third terminals formed with a third contact portion, a third conductive portion and a first connecting portion, each of the fourth terminals formed with a fourth contact portion, a fourth conductive portion and a second connecting portion,
• wherein the first module is stacked on the second module and the first module is configured to move toward two positions,
• a first position where the third conductive portion 412 and the fourth conductive portion 422 contact with the corresponding first conductive portion 212 and the second conductive portion 222 and as a result the first module is launched to a use stage to conform to USB 3.0 Type-A connector interface, and
• a second position where the third conductive portion 412 and the fourth conductive portion 422 are detached from the corresponding first conductive portion 212 and the second conductive portion 222 and as a result the first module is launched to a retracted stage and the second module is launched to a use stage to conform to USB Type-C connector interface, and
• a housing enveloping the exterior of the first module, the housing comprising a hole, and two protrusions formed on the opposite sides of the hole respectively, to secure the second module.
