[0022] Example 1

[0023] refer to Figure 1-Figure 4 The present embodiment provides an AC charging pile structure, comprising a panel 1, a shell 2, a bottom plate 3, a mounting plate 4 and a terminal 5; the shell 2 is fixed between the panel 1 and the bottom plate 3 to form a closed chamber, and the terminal 5 is located in the closed chamber; the side of the mounting plate 4 close to the bottom plate 3 is connected to the shell 2, and the side of the mounting plate 4 away from the bottom plate 3 is used to be fixed on the wall; the shell 2 is provided with a first opening 21 and a second opening 22 connecting the closed chamber with the outside of the shell, and a cover plate 23 for opening or closing the first opening 21 and the second opening 22; the bottom plate 3 has a through hole 31, and the wire outside the shell passes through the through hole 31 to connect with the terminal 5.

[0024] Specifically, in this embodiment, the AC charging pile structure includes a panel 1, a shell 2, a base plate 3, a mounting plate 4 and a wiring terminal 5.

[0025] The housing 2 is fixed between the panel 1 and the bottom plate 3 to form a closed chamber, which can be loaded with other electronic components, such as a circuit board and an RF board, to realize other functions of the AC charging pile. The wiring terminal 5 is located in the closed chamber. In this embodiment, there are two wiring terminals 5, one for the access and installation of the power line, and the other for the access and installation of the signal line.

[0026] The shell 2 is provided with a first opening 21 and a second opening 22, and the first opening 21 and the second opening 22 are arranged relatively parallel and distributed at both ends of the shell 2. The first opening 21 and the second opening 22 are arranged at an angle to the panel 1, respectively. It can be understood that the panel 1 is located on the front of the AC charging pile structure, and the two openings are located on the side of the AC charging pile structure. The first opening 21 is used for access and installation of the power cord, and the second opening 22 is used for access and installation of the signal cord. In detail, the wiring terminals 5 are respectively arranged near the first opening 21 and the second opening 22, so that wiring is more convenient.

[0027] The shell 2 is also provided with a cover plate 23 for opening or closing the first opening 21 and the second opening 22. The cover plate 23 is adapted to the opening cross-sections of the first opening 21 and the second opening 22 to completely cover the openings. The cover plate 23 is locked on the first opening 21 and the second opening 22 by fasteners. In this embodiment, the fasteners are preferably screws. When wiring is required, the screws are unscrewed and removed, and then the cover plate 23 is removed from the two openings to perform wiring operations; after the wiring is completed, the cover plate 23 is put back in place, and then the screws are screwed in and tightened to complete the closure of the shell 2. In order to ensure good sealing of the first opening 21 and the second opening 22, a sealing ring is provided between the first opening 21 and the second opening 22 and the cover plate 23 to isolate water or water vapor.

[0028] The bottom plate 3 has a through hole 31, and the circuit outside the shell passes through the through hole 31 to connect with the corresponding wiring terminal 5 located in the closed chamber. It should be noted that the first opening 21 and the second opening 22 connect the closed chamber with the outside of the shell. When the user needs to connect the wires, the cover plates 23 on both sides are removed, and the wiring operation is performed directly in the closed chamber through the openings on the two sides. The circuit passes through the through hole 31 of the bottom plate 3 and is connected to the wiring terminal 5 in the closed chamber. The access and installation of the power line can be operated through the first opening 21, and the access and installation of the signal line can be operated through the second opening 22.

[0029] The side of the mounting plate 4 close to the bottom plate 3 is connected to the shell 2, and the side of the mounting plate 4 away from the bottom plate 3 is used to be fixed on the wall. Specifically, the side of the shell 2 close to the mounting plate 4 has a card slot 24, and the card slot 24 is used to cooperate with the mounting plate 4 to connect the shell 2. The side of the mounting plate 4 close to the shell 2 has a card 41 for engaging the card slot 24, and the number of the card slots 24 and the card 41 is equal. When the card 41 is engaged in the card slot 24, the shell 2 is further tightened by screws. The mounting plate 4 is fixed to the wall by expansion screws.
