The base 10 is used to mount and fix to the outer casing (not shown) of equipment such as a computer or server. The circuit board 20 supports the adapter 40 and is integrally fixed to the base 10 with the adapter 40. The insertion interface of the electrical connector 30 is exposed outward on the surface of the base 10, providing a plug-in function. The structure of each component is described in detail below.

Figure 2 As shown, the fixing post 13 protrudes upward to support the circuit board 20, and has an upward-facing positioning screw hole 131 for fixed connection with the circuit board 20 and the adapter 40. The front cover plate 12 is integrally connected to the base plate 11, and the front cover plate 12 extends vertically upward from the front edge of the base plate 11. The front cover plate 12 has a plug interface 121 corresponding to the electrical connector 30, which is distributed on the outer surface of the front cover plate 12 and penetrates the front cover plate 12 inward. Preferably, the two ends of the front cover plate 12 have a pair of outwardly protruding ends 18, which can serve as a limit and prevent fooling.

[0021] The circuit board 20 is mounted above the base plate 11 of the base 10 and is parallel to the base plate 11. It is supported by the fixing posts 13 on the base plate 11, creating a gap between the base plate 11 and the circuit board 20. The circuit board 20 has fixing holes 21 that correspond to the positioning screw holes 131 on the fixing posts 13. The circuit board 20 is fixed to the base 10 through the fixing holes 21 and the positioning screw holes 131.
