Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification to understand and read by those skilled in the art, and are not used to limit the practical limit conditions of the present invention, so they have no technical significance, and any structural modification, ratio relationship change or size adjustment should still fall within the scope of the present invention without affecting the function and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Referring to fig. 1, an adapter 11 is provided with a compatible port 111, where the compatible port 111 includes a first port 1111 and a second port 1112, and the first port 1111 and the second port 1112 are connected in parallel inside the adapter 11 or in the compatible port 111 in parallel, and share a set of power circuit or protocol control circuit. Referring to fig. 3, fig. 3 shows an internal connection circuit of the compatible port 311, the compatible port 311 includes a first port 3111 and a second port 3112, input terminals Vbus/GND/D +/D-of the first port 3111 and the second port 3112 are connected in parallel and share a protocol chip 314 and a port switch 313, and the port switch 313 is connected in parallel with an output terminal of the power circuit 312. The first port 3111 and the second port 3112 share the same port control line, and a complex power allocation strategy is not considered. In a specific embodiment of the present invention, the first port 3111 is a Type-C port, the second port 3112 is a Type-a port, the Type-a port, and the input terminals Vbus, GND, D +, D-signals of the Type-C port share the same signal line, and are directly short-circuited or short-circuited by equivalent small resistors, small inductors, small magnetic beads, and the like, and only 1 set of port control lines is needed to connect a Type-a device or a Type-C device to the port.

Referring to fig. 2, the adapter 21 is provided with compatible ports 211, where the compatible ports 211 include a first port 2111 and a second port 2112, and also provided with ports 212 and 213, so as to provide more choices for users, and the

compatible ports

211, 212 and 213 are independent ports respectively.

Referring to fig. 4,

tongue cores

41111 and 41121 of the first port 4111 and the second port 4112 are enclosed in a port module to form a compatible port 411. Thus, an interlocking structure is formed, when a device is inserted into port 4111, no device can be inserted into port 4112, and when a device is inserted into port 4112, no device can be inserted into port 4111.

Referring to fig. 5, in another embodiment of the present invention, the first port 5111 and the second port 5112 are installed close to each other, and the interlocking purpose is achieved by using the shielding effect of the head of the inserting device, referring to fig. 5(b), the second plug 52 is inserted into the second port 5112, and the second plug 52 shields a part of the area of the first port 5111, so that the plug matched with the first port 5111 cannot be inserted into the first port 5111.
