Please refer to FIG. 4 to FIG. 6 . FIG. 4 to FIG. 6 are respectively enlarged schematic views of the connector mechanism 16 in different operating states according to an embodiment of the present invention.

The plug connector 20 is disposed on the base 18, and the receptacle connector 26 is disposed on the carrier 24. The number of via structures 28 is at least one, but in order for the plug connector 20 to properly engage the receptacle connector 26, the number of via structures 28 is preferably two. The via structure 28 is disposed on the pedestal 18 and is located on both sides of the plug connector 20, respectively. The number of pillar structures 22 corresponds to the number of via structures 28, and the pillar structures 22 are disposed on the carrier 24 and are located on the side of the receptacle connector 26.

The pillar structure 22 includes a first cylinder 30 and a second cylinder 32. Both ends of the first cylinder 30 are connected to the carrier 24 and the second cylinder 32, respectively. The second cylinder 32 is the free end 221 of the pillar structure 22 with respect to one end of the first cylinder 30 (the end to which the first cylinder 30 is not connected). Before the plug connector 20 contacts the receptacle connector 26, the free end 221 is first inserted into the corresponding via structure 28 to provide a positioning effect. In particular, the width of the first cylinder 30 is W1, the width of the second cylinder 32 is W2, and the width W2 is greater than the width W1.

In this way, the protruding member (via structure 28) is disposed at the connection end of the external electronic device 14, and there is no protruding member at the connection end of the portable electronic device 12 (because the pillar structure 22 is aligned with the socket connector 26) It conforms to the actual industrial design application and has a more beautiful appearance.

The present invention further defines the structural features of the pillar structure 22 and the via structure 28. The difference in clearance between the outer wall of the structure of the second cylinder 32 and the inner wall of the opening of the second section 36 is defined as the difference in width D1 between the outer wall of the structure of the first cylinder 30 and the inner wall of the opening of the second section 36. The gap difference is defined as the width difference D1'. The difference in the gap between the outer wall of the structure of the plug connector 20 and the inner wall of the opening of the receptacle connector 26 is defined as the difference in width D2. The difference in the gap between the outer wall of the structure of the second cylinder 32 and the inner wall of the space of the first section 34 is defined as the width difference D3. Here, the width difference D1 < width difference D2, width difference D2 < width difference D3, and width difference D2 < width difference D1'.
