DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] The present application embodiment discloses a mounting structure of a charging gun circuit board, referring to Figure 1 and Figure 2 , comprising a shell 1, an installation shell 2 is integrally formed on the inner wall of the shell 1, the inner wall of the installation shell 2 and the inner wall of the shell 1 together form an installation chamber 3, and the installation chamber 3 has an opening. The installation shell 2 is fixedly installed with a fixing rod group on two opposite inner walls along the length direction thereof. In this embodiment, the fixing rod group is composed of two fixing rods 15 parallel to each other, and each fixing rod 15 has a guide portion 17 at one end close to the opening of the installation shell 2. The two fixing rods 15 of the same group and the inner wall of the installation shell 2 together form a slide groove 16. A stop block 18 is integrally formed inside the installation shell 2, and the stop block 18 is located at one end of the installation shell 2 away from the opening of the installation shell 2.

[0037] Reference Figure 1 and Figure 2 When installing the circuit board, the operator inserts the two opposite sides of the circuit board into the two slide grooves 16 respectively, and pushes the circuit board to slide along the length direction of the slide groove 16 toward the inside of the installation housing 2. When the circuit board slides to the set installation position, the stopper 18 blocks the circuit board from sliding further, so that the circuit board stops at the set installation position. When inserting the two opposite sides of the circuit board into the slide grooves 16, the guide portion 17 helps to guide the two sides of the circuit board to be inserted into the corresponding slide grooves 16 respectively, thereby helping to improve the convenience of inserting the circuit board into the slide groove 16.

[0038] Reference Figure 1 and Figure 2 A sealing assembly 4 is provided inside the mounting chamber 3, and the sealing assembly 4 includes a sealing block 41 and a sealing ring 42. The sealing block 41 is placed inside the mounting shell 2 at one end close to the opening. The sealing ring 42 is integrally formed with the sealing block 41 and is located at the circumferential periphery of one end of the sealing block 41. The outer ring of the sealing ring 42 is interference fit with the inner wall of the mounting shell 2.

[0039] Reference Figure 1 and Figure 3 A fixed cover 7 is fixedly sleeved on the periphery of the sealing block 41. The fixed cover 7 is arranged adjacent to the sealing ring 42. The circumferential outer wall of the fixed cover 7 abuts against the inner wall of the mounting shell 2. An elastic hook 8 is fixedly installed on the fixed cover 7. A slot 9 is penetrated through the shell 1, and the elastic hook 8 is engaged in the slot 9.

[0040] Reference Figure 3 and Figure 4 The sealing block 41 is provided with a plurality of first wire holes 5, and the side wall of the sealing block 41 is provided with a plurality of tapered holes 6, each tapered hole 6 is located at the circumferential periphery of a first wire hole 5 and is connected to the first wire hole 5. The fixing cover 7 is provided with a second wire hole 10 connected to the first wire hole 5.

[0041] Reference Figure 2 and Figure 5 When the circuit board is placed in the installation position, the sealing block 41 and the fixed cover 7 are inserted into the installation shell 2 along the opening of the installation shell 2. During the insertion process, the elastic hook 8 is deformed by the pressure of the inner wall of the shell 1. When the elastic hook 8 moves to the bottom of the card slot 9, the pressure of the inner wall of the shell 1 disappears, and the elastic hook 8 is connected to the card slot 9 under the action of its own elastic force, thereby driving the fixed cover 7 and the sealing block 41 to stop moving, so that the fixed cover 7 and the sealing block 41 are fixed inside the installation shell 2.

[0042] Reference Figure 2 and Figure 5When the sealing block 41 is fixed in the installation housing 2, the sealing block 41 and the sealing ring 42 can block the opening of the installation housing 2, thereby ensuring the sealing effect of the installation chamber 3. At the same time, the sealing block 41 is pressed against the side of the circuit board, which helps to cooperate with the stop block 18 and the fixing rod 15 to limit the position of the circuit board, so that the circuit board is fixedly placed in the installation position, which helps to improve the convenience of the operation steps during the installation of the circuit board, thereby improving the installation efficiency of the circuit board.

[0043] Reference Figure 1 The top surface of the housing 1 is provided with a clearance opening 11, and an elastic pressing piece 12 is fixedly installed on the top surface of the housing 1. The elastic pressing piece 12 is located inside the clearance opening 11, and one end of the elastic pressing piece 12 is fixedly connected to the housing 1, and the other end of the elastic pressing piece 12 is a movable end. The operator presses the movable end of the elastic pressing piece 12 to help press the touch switch on the circuit board.

[0044] Reference Figure 1 and Figure 2 A mounting groove 13 is provided on the top surface of the housing 1, and the card slot 9 and the clearance opening 11 are both located inside the mounting groove 13. A sealing sticker 14 is fixedly attached to the inside of the mounting groove 13, and the shape of the sealing sticker 14 is consistent with the shape of the mounting groove 13. The sealing sticker 14 helps to seal the card slot 9 and the clearance opening 11, thereby helping to prevent external water from entering the interior of the mounting housing 2 through the card slot 9 and the clearance opening 11, further improving the sealing effect of the mounting housing 2, and further ensuring the safety of the circuit board.

[0045] The implementation principle of the embodiment of the present application is as follows: when installing the circuit board, the operator inserts the two opposite sides of the circuit board into the two slide grooves 16 respectively, and pushes the circuit board to slide along the length direction of the slide groove 16 toward the inside of the installation housing 2. When the circuit board slides to the set installation position, the stop block 18 blocks the circuit board from sliding further, so that the circuit board stops at the set installation position.

[0046] When the circuit board is placed in the installation position, the sealing block 41 and the fixed cover 7 are inserted into the installation shell 2 along the opening of the installation shell 2. During the insertion process, the elastic hook 8 is deformed by the pressure of the inner wall of the shell 1. When the elastic hook 8 moves to the bottom of the slot 9, the pressure of the inner wall of the shell 1 disappears, and the elastic hook 8 is connected to the slot 9 under the action of its own elastic force, thereby driving the fixed cover 7 and the sealing block 41 to stop moving, so that the fixed cover 7 and the sealing block 41 are fixed inside the installation shell 2.

[0047] When the sealing block 41 is fixed in the installation housing 2, the sealing block 41 and the sealing ring 42 can block the opening of the installation housing 2, thereby ensuring the sealing effect of the installation chamber 3. At the same time, the sealing block 41 is pressed against the side of the circuit board, which helps to cooperate with the stop block 18 and the fixing rod 15 to limit the position of the circuit board, so that the circuit board is fixedly placed in the installation position, which helps to improve the convenience of the operation steps during the installation of the circuit board, thereby improving the installation efficiency of the circuit board.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
