In this way, in the case where the external device is connected to the portable electronic device 30 through the plug type connection device 200, the waterproof effect can still be achieved.

In the case where the plug type connecting device 200 and the socket type connecting device 100 are butted against each other, and the engaging member 251 is engaged with the second card slot 117, the nut 256 can be further tightened to achieve a better waterproof effect. Specifically, the nut 256 can be rotated first until after contacting the outer casing, and then the rotation is continued, and the nut 256 is pressed against the outer casing 210 and the pressing member 255 is directed away from the nut 256 toward the outer casing 210 (ie, away from the outer casing 210). The direction of the outer casing 210 is moved, and the connecting member 252 is pulled to bring the connecting member 252 close to the nut 256, thereby moving the engaging member 251 toward the inside of the outer casing 210 (ie, the engaging member 251 is close to the outer casing 210). At this time, the engaging member 251 in the second card slot 117 exerts a stress toward the outer casing 210 on the waterproof outer casing 110, forcing the socket type connecting device 100 to be closer and closer to the plug type connecting device 200.

When the plug-type connecting device 200 is to be detached from the portable electronic device 30 (to separate the plug-type connecting device 200 from the socket-type connecting device 100), the nut 256 is first loosened, that is, the nut 256 is reversed. Rotating away from the outer casing 210; correspondingly, the engaging member 251 in the second engaging groove 117 no longer exerts stress on the waterproof outer casing 110 toward the outer casing 210; then, pressing the two pressing members 253 to cause the two engaging members 251 Adjacent to each other, the engaging member 251 is aligned with the opening of the second card slot 117 and can be disengaged by the second card slot 117, while the plug-type connecting device 200 and the socket-type connecting device 100 can be separated from each other.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art, and some modifications and refinements that do not depart from the spirit of the present invention should be included in the creation. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
