The receiving portion 3101 is provided with a stopping portion 315 on the bottom surface of the front end thereof, and the stopping portion 315 is used for blocking the first plug 1 or the second plug 2 to prevent the first plug 1 or the second plug 2 from being excessive. Rotating to turn out the bottom surface of the third insulative housing 31. In a preferred embodiment, the thickness of the stopping portion 315 is set to a certain thickness, so that the composite adapter plug 100 is flat after the first plug 1 and the second plug 2 are rotated into the third insulative housing 31. shape. The front end side surface of the receiving portion 3101 is provided with a stud 316. When the first plug 1 or the second plug 2 is rotated into the third insulative housing 31, the stud 316 clamps the first plug 1 or the second plug. 2. The holding of the third plug 3 and the first plug 1 or the second plug 2 is ensured to be stable. The third plug connector 32 is connected to the cable 4 directly via a wire. The third insulative housing 31 includes an upper housing 33 and a lower housing 34 , and the upper housing 33 and the lower housing 34 are fastened to form a third insulative housing 31 . The upper casing 33 and the lower casing 34 are hollow to accommodate the wires connecting the connector and the cable 4. When assembling, the first plug 1, the second plug 2, the third plug connector 32, and the cable 4 are first assembled to the lower case 34; then the first plug 1, the second plug 2, and the third plug connector 32 are implemented. And the electrical connection between the cables 4; finally, the upper casing 33 is fastened to complete the assembly. The first plug 1, the second plug 2, and the third plug 3 are separately The cable 4 is electrically connected (ie, the first plug 1, the second plug 2, and the third plug 3 are electrically connected to the cable 4 without being mated to each other), so that any plug is damaged and does not affect. The other plugs work properly.

Since the first plug 1, the second plug 2 and the third plug 3 are respectively electrically connected to the cable 4, the damage of any plug does not affect the normal operation of the other plugs, that is, the composite switch The reliability of the plug 100 is high.

Further, since the first plug 1, the second plug 2, and the third plug 3 are respectively electrically connected to the cable 4, and the first plug 1 and the second plug 2 are respectively provided with the first socket connector 13 and the first The two-socket connector 23 is such that the first socket connector 13 and the second socket connector 23 are also electrically connected to the cable 4 separately. With the development of science and technology, data lines with socket connectors will become a trend. For example, with the development of OTG (On-The-Go) technology, one end has a Micro USB plug connector and the other end has a USB socket. The connector's data line is widely used. Therefore, the composite adapter plug 100 of the present invention will satisfy the development trend of the technology.
