The pair of frequency bumps 1625 can be columnar, so that the frequency bump 1625 can be well adapted to the frequency button hole. 1248. It can be understood that, corresponding to the distribution of the USB data hole 1246, the data card hole 1247, and the counter frequency button hole 1248, the USB bump 1623, the data card bump 1624, and the counter frequency bump 1625 are also arranged in a triangle, and the USB bump 1623 is arranged. The data card bumps 1624 are respectively located on opposite sides of the pair of frequency bumps 1625. Specifically, the pair of frequency bumps 1625 may correspond to the midpoint positions of the connections of the USB bumps 1623 and the data card bumps 1624. Of course, the specific type and number of the bumps 162 are not limited to the discussion in the above examples. The bumps 162 may also include only one or two of the USB bumps 1623, the data card bumps 1624, and the pair of frequency bumps 1625. The shape of the bump 162, the arrangement and the positional relationship between the plurality of bumps 162 may be adjusted correspondingly according to the specific shape of the plurality of data holes 1245, the arrangement and positional relationship of the plurality of data holes 1245.
