a concave part 12 is formed on the shell of the mobile terminal or the portable device 1, the data interface 11 is arranged on the bottom surface of the concave part 12, and a vertical surface 13 which surrounds the data interface 11 and is parallel to the plugging direction of the data interface 11 is formed on the side wall of the concave part 12;

In the above embodiment, the interface types of the input terminal 21 and the output terminal 22 may be selected according to design requirements. For example, the input terminal 21 and the output terminal 22 may use the same USB interface, such as a TYPE-C interface, to implement interface switching of C-C conversion. Of course, the input end 21 and the output end 22 may also select a different interface from a plurality of USB interfaces and lighting interfaces to realize interface conversion of other combinations.

Obviously, in order to make an electrical connection between the input 21 and the output 22, an interface conversion circuit for connecting the input 21 and the output 22, respectively, will be provided inside the housing 23. As shown in fig. 3, in the above embodiment, the interface conversion circuit is specifically a circuit board 25 provided in the housing 23.

Referring to fig. 2, when the adapter 2 is plugged into the data interface 11 through the input end 21, the output end 22 of the adapter 2 extends from the end of the extending end 27 along the extending direction of the extending end 27, the housing 23 of the adapter 2 is abutted against the vertical face 13 of the recess 12 through the vertical wall 24 on the side facing away from the output end 22, the adapter 2 provides a connection port with the output end 22 after interface type conversion, and the external force applied by the operation of plugging the external device or the data line into the output end 22 is counteracted, so that the mechanical structure of the input end 21 and the data interface 11 is not damaged.
