[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] like Figures 1 to 4 As shown, this application embodiment provides a circuit board fixing device, including: a housing 1, the housing 1 having a mounting through hole 11 and a mounting part 12; a circuit board 2; an insulating bracket 3, the insulating bracket 3 including a bracket body 31 and a first snap-fit ​​member 32, the first snap-fit ​​member 32 being connected to the bracket body 31, at least a portion of the bracket body 31 being inserted into the mounting through hole 11, the bracket body 31 being detachably connected to the housing 1 through the mounting part 12, and the circuit board 2 being snapped into the insulating bracket 3 through the first snap-fit ​​member 32.

[0029] The fixing device in this embodiment of the application detachably connects the insulating bracket 3 to the housing 1, and clips the circuit board 2 onto the insulating bracket 3, thereby mounting the circuit board 2 onto the housing 1. In this embodiment of the application, the circuit board 2 is mounted onto the housing 1 via the insulating bracket 3. When mounting the circuit board 2 onto the housing 1, screws are not required for tightening, thus avoiding damage to the circuit board 2 when tightening screws and preventing damage to the circuit board 2 during installation.

[0030] To enable the circuit board 2 to engage with the insulating card holder 3, a first engaging groove 33 is provided on the card holder body 31, which mates with the circuit board 2. When the circuit board 2 engages with the insulating card holder 3, the circuit board 2 is engaged within the engaging groove. To prevent the circuit board 2 from falling out of the first engaging groove 33, in this embodiment, a first engaging member 32 is located on the side of the first engaging groove 33, and the insulating card holder 3 uses the first engaging member 32 to engage the circuit board 2 within the first engaging groove 33.

[0031] To ensure a more secure installation of the circuit board 2 within the first latching slot 33, two first latching members 32 are provided, located on opposite sides of the first latching slot 33. These two first latching members 32 engage the circuit board 2 from two different sides of the first latching slot 33, further securing the circuit board 2 and preventing it from detaching.

[0032] To facilitate the mounting of the circuit board 2 onto the insulating card holder 3, the first snap-fit ​​component 32 in this embodiment includes a snap-fit ​​handle 321 and a snap-fit ​​protrusion 322. The snap-fit ​​handle 321 is connected to the card holder body 31, and the snap-fit ​​handle 321 is connected to the snap-fit ​​protrusion 322. The snap-fit ​​handle 321 drives the snap-fit ​​protrusion 322 to move closer to or further away from the interior of the first snap-fit ​​groove 33. In the initial position, at least a portion of the snap-fit ​​protrusion 322 is located within the first snap-fit ​​groove 33.

[0033] In one embodiment, both the insulating card holder 3 and the first snap-fit ​​member 32 are made of plastic material, which has a certain degree of elasticity. When it is necessary to install the circuit board 2 into the insulating card holder 3, the snap-fit ​​handle 321 is pressed away from the interior of the first snap-fit ​​groove 33. The snap-fit ​​handle 321 drives the snap-fit ​​protrusion 322 to move away from the interior of the first snap-fit ​​groove 33, and then the circuit board 2 is placed in the first snap-fit ​​groove 33. After the circuit board 2 is placed in the first snap-fit ​​groove 33, the installed snap-fit ​​handle 321 is released. The snap-fit ​​handle 321 returns to its initial position under the action of elasticity and drives the snap-fit ​​protrusion 322 to move closer to the interior of the first snap-fit ​​groove 33, so that at least a part of the snap-fit ​​protrusion 322 is located in the first snap-fit ​​groove 33. The snap-fit ​​protrusion 322 fixes the circuit board 2 in the first snap-fit ​​groove 33, preventing the circuit board 2 from falling out of the first snap-fit ​​groove 33.

[0034] Similarly, when removing the circuit board 2 from the insulating bracket 3, press the snap-fit ​​handle 321 away from the inside of the first snap-fit ​​groove 33. The snap-fit ​​handle 321 drives the snap-fit ​​protrusion 322 away from the inside of the first snap-fit ​​groove 33, and then the circuit board 2 can be removed from the first snap-fit ​​groove 33. This application allows for easy installation and removal of the circuit board 2 from the insulating bracket 3 through the snap-fit ​​handle 321, without damaging the circuit board 2 during installation and removal. It also reduces the use of screws during the installation of the circuit board 2, improving installation efficiency and reducing costs.

[0035] In one embodiment, to enable detachable installation of the insulating card holder 3 and the housing 1, the mounting part 12 is a mounting slot located on the side of the mounting through hole 11 and connected to the mounting through hole 11. The insulating card holder 3 also includes a second snap-fit ​​member 34, which is connected to the card holder body 31. The second snap-fit ​​member 34 cooperates with the mounting slot and is snapped into the housing 1 through the mounting slot.

[0036] Furthermore, the second snap-fit ​​component 34 is also made of plastic. The second snap-fit ​​component 34 includes a snap-fit ​​connecting plate 341 and a snap hook 342, with the snap hook 342 connected to the snap-fit ​​connecting plate 341. The bottom of the snap-fit ​​connecting plate 341 is connected to the main body 31 of the mounting base, and the snap hook 342 is connected to the top of the snap-fit ​​connecting plate 341, engaging within a mounting slot. A gap exists between the side of the snap-fit ​​connecting plate 341 and the main body 31 of the mounting base.

[0037] To ensure a more secure installation of the insulating bracket 3 on the housing 1, this embodiment uses two second latching members 34 and two mounting slots, with the two second latching members 34 positioned opposite each other on the bracket body 31. The two second latching members 34 work together to secure the insulating bracket 3 to the housing 1, making the installation more robust.

[0038] The card holder body 31 has a limiting plate 35, and the first card slot 33 is placed on the first limiting plate 35. At least one of the length and width of the first limiting plate 35 is greater than the outer diameter of the mounting through hole 11. In this embodiment, the length or width of the first limiting plate 35 is greater than the outer diameter of the mounting through hole 11, and the insulating card holder 3 is limited by the first limiting plate 35 during installation.

[0039] When the insulating bracket 3 is installed with the housing 1, the bracket body 31 can be inserted into the mounting through hole 11 of the housing 1, and the insulating bracket 3 and the housing 1 can be engaged through the second snap-fit ​​member 34 and the mounting slot. When the insulating bracket 3 is disassembled from the housing 1, since there is a gap between the side of the snap-fit ​​connecting plate 341 and the bracket body 31, the snap-fit ​​connecting plate 341 can be pressed towards the bracket body 31, so that the snap hook 342 can be disengaged from the mounting slot, and then the insulating bracket 3 can be removed from the housing 1.

[0040] In one embodiment, the fixing device further includes a patch 4, which is attached to the housing 1 and covers the mounting through hole 11.

[0041] The mounting device of this application completes the installation of the circuit board 2 on the housing 1 by mounting the insulating bracket 3 onto the housing 1 and then snapping the circuit board 2 onto the insulating bracket 3. The circuit board 2 does not require screws for locking during installation, avoiding damage to the circuit board 2 caused by screwing. Since the insulating bracket 3 is made of plastic, mounting the circuit board 2 onto the insulating bracket 3 effectively prevents the risk of leakage caused by the circuit board 2 being in direct contact with metal.

[0042] The circuit board 2 described in this application is a PCB board or a PCBA board.
