[0046] In some embodiments, the first interference portion 43 may be spaced apart from the second interference portion 44 to form a clearance region 1005 between the first interference portion 43 and the second interference portion 44. That is, the first circuit board 10 has a clearance region 1005 located between the first interference portion 43 and the second interference portion 44.

A grounding trace 1011 may be disposed on the outer side of the first routing group 13, and disposed on the side of the first interference portion 43 and the second interference portion 44 near the plurality of first sub-interfaces 61. The placement of the grounding trace 1011 can reduce the influence of interference sources 40, such as the first interference portion 43 and the second interference portion 44, on the routing circuit 101, such as the first routing group 13, and reduce interference to the signals of the docking station 100.

[0048] In some embodiments, the first wiring group 13 may include a first wiring section 131, a second wiring section 132, and a third wiring section 133 connected in series.

In some embodiments, the second trace portion 132 is closer to the clearance region 1005 than the second edge 12 to achieve a reasonable arrangement of the first circuit board 10.

[0050] In some embodiments, compared to the first interference portion 43 and the second interference portion 44, the first routing portion 131 and the third routing portion 133 may be closer to the second edge 12, thereby reducing the influence of the interference source 40, such as the first interference portion 43 and the second interference portion 44, on the routing circuit 101, such as the first routing portion 131 and the third routing portion 133, and reducing interference to the signal of the docking station 100.

Because the second wiring group 14 is disposed on the second surface 1002, it is less affected by the first interference part 43 and the second interference part 44, thereby reducing interference to the signal of the expansion dock 100.

[0055] In some embodiments, a grounding trace 1011 is provided on the outer side of the second wiring group 14 to minimize the impact of the first interference part 43 and the second interference part 44, thereby reducing interference to the signal of the expansion dock 100.

[0057] In some embodiments, the second surface 1002 is provided with a first auxiliary part 431 that cooperates with the first interference part 43 in the area corresponding to the first interference part 43, thereby reducing the occupancy of the first surface 1001. In addition, the first auxiliary part 431 does not affect the wiring circuit 101, and can therefore be provided on the second surface 1002, thereby reducing the impact on the second circuit board 20 and reducing interference to the signal of the expansion dock 100.

[0058] In some embodiments, the second surface 1002 has a second auxiliary part 441 that cooperates with the second interference part 44 in the area corresponding to the second interference part 44, thereby reducing the occupancy of the first surface 1001. In addition, the second auxiliary part 441 may not affect the wiring circuit 101, or may have as little impact as possible, and may therefore be provided on the second surface 1002, thereby reducing the impact on the second circuit board 20 and reducing interference to the signal of the expansion dock 100.

[0059] In some embodiments, the second wiring group 14 is disposed on one side of the first auxiliary portion 431 and the second auxiliary portion 441 near the plurality of first sub-interfaces 61. In some embodiments, the middle portion of the second wiring group 14 is closer to the first auxiliary portion 431 and the second auxiliary portion 441 than the second edge 12.

[0060] Please see Figure 3 and Figure 4 The first edge 11 may be provided with a USB signal interface 33, such as a first USB connector 56. In some embodiments, the first USB connector 56 may transmit a USB 4.0 signal, but it may also be other types of USB signals.

[0064] In some embodiments, the first board-to-board connector 15 may also be electrically connected to the second wiring group 14 to enable the transmission of USB signals between the plurality of first sub-interfaces 61 and the second circuit board 20.

[0065] In some embodiments, please refer to Figure 4 The wiring circuit 101 may include a third wiring group 16 disposed on the second surface 1002. The third wiring group 16 may electrically connect the first board-to-board connector 15 and the first USB connector 56 to realize the transmission of USB signals between the first USB connector 56 and the second circuit board 20.

[0066] In some embodiments, the third wiring group 16 may be located between the second wiring group 14 and the first auxiliary part 431 and the second auxiliary part 441. Furthermore, when a grounding trace 1011 is provided on the outside of the third wiring group 16, the influence of the second auxiliary part 441 and the second wiring group 14 on the third wiring group 16 can be minimized, thereby reducing interference with the signals of the docking station 100. In some embodiments, when a grounding trace 1011 is provided on the outside of the second wiring group 14, the influence of the third wiring group 16 on the second wiring group 14 can be minimized, thereby reducing interference with the signals of the docking station 100.

[0067] Please see Figure 5 The interference source 40 may include a third interference part 45 and a fourth interference part 46 disposed on the fourth surface 1004. The placement of the third interference part 45 and the fourth interference part 46 on the fourth surface 1004 can reduce the impact on the wiring circuit 101, such as the first wiring group 13, the second wiring group 14 and the third wiring group 16, thereby reducing interference to the signals of the docking station 100.
