[0069] In related technologies, the PCB of a touchscreen is fixed by clips, and there is a gap between the PCB and the clips, which makes the PCB prone to shaking after installation. Furthermore, the Type-C interface of the PCB requires frequent plugging and unplugging, further leading to loosening or displacement, resulting in low structural reliability.

[0070] In view of this, in one aspect of the present disclosure, a circuit board assembly is provided that can improve structural reliability.

Figure 2 This is a schematic diagram of a circuit board according to some embodiments of the circuit board assembly of this disclosure. Figure 3 This is a schematic diagram of a mounting plate according to some embodiments of the circuit board assembly of this disclosure. Figure 4 This is a schematic diagram of a housing according to some embodiments of the circuit board assembly of this disclosure, with reference to... Figures 1-4 The circuit board assembly includes: mounting plate 1, housing 2 and circuit board 3.

[0072] Mounting plate 1 has a limiting component that protrudes from the plate body of mounting plate 1, housing 2 is connected to mounting plate 1 and forms a receiving space between mounting plate 1, and circuit board 3 is disposed in the receiving space.

[0073] The limiting assembly includes a first limiting structure 41 and a second limiting structure 42 spaced apart along a first direction X. The first limiting structure 41 and the second limiting structure 42 are positioned close to the Type-C interface 31 of the circuit board 3. The circuit board 3 is snapped between the first limiting structure 41 and the second limiting structure 42 along the first direction X. The first direction X is parallel to the thickness direction of the circuit board 3. The width spacing between the first limiting structure 41 and the second limiting structure 42 along the first direction is equal to the thickness of the circuit board 3, approximately 1.6 mm.

[0074] The circuit board 3 is installed on one side of the mounting plate 1 by a limiting device. The housing 2 is fastened to the side of the mounting plate 1 where the circuit board 3 is set. The side of the mounting plate 1 away from the circuit board 3 can be equipped with a liquid crystal display element.

[0075] Circuit board 3 includes, but is not limited to, a PCB. The Type-C interface 31 of circuit board 3 includes, but is not limited to, being located at a lower position, such as... Figure 2 The mounting port 32 facilitates wiring connections and allows operators to easily plug and unplug circuits. Limiting components are provided along the edge contour of the circuit board 3, including but not limited to limiting the circuit board 3 in the circumferential and thickness directions.

[0076] In this embodiment, the first limiting structure 41 and the second limiting structure 42 are positioned close to the mounting plate 1 and the Type-C interface 31 of the circuit board 3, respectively. The circuit board 3 is engaged between the first limiting structure 41 and the second limiting structure 42 along the thickness direction of the circuit board 3. This restricts the loosening or displacement of the circuit board 3, especially the area around the Type-C interface 31, caused by frequent plugging and unplugging. This improves the reliability of the circuit board 3 in the circuit board assembly and reduces the risk of data transmission interruption or power supply failure caused by unstable connection at the Type-C interface 31.

[0077] Figure 5 This is a partial cross-sectional view of some embodiments of the circuit board assembly according to the present disclosure. Figure 5 The cross-sectional position and Figure 1 The position of section AA corresponds to the reference. Figures 1-5 In some embodiments, the second limiting structure 42 is located on the side closer to the housing 2 relative to the first limiting structure 41 along the first direction X. The Type-C interface 31 of the circuit board 3 is disposed below the first limiting structure 41 and the second limiting structure 42, and is located between the first limiting structure 41 and the second limiting structure 42 along the first direction X.

[0078] The first limiting structure 41 is disposed on the side near the mounting plate 1, and the second limiting structure 42 is disposed on the side near the housing 2. The second limiting structure 42 includes, but is not limited to, a limiting base extending along the first direction from the plate body of the mounting plate 1 toward the side near the housing 2, so as to further limit the circuit board 3 in the vertical direction.

[0079] In this embodiment, the circuit board 3 is snapped between the first limiting structure 41 and the second limiting structure 42, and the Type-C interface 31 extends downward between the first limiting structure 41 and the second limiting structure 42. The limiting base, the first limiting structure 41 and the second limiting structure 42 form a circumferential and thickness-direction limiting on the Type-C interface 31 of the circuit board 3, which helps to further improve the strength of the Type-C interface 31 of the circuit board 3, reduce the inconvenience or misoperation caused by the instability of the Type-C interface 31, and reduce the probability of failure.

[0080] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the first limiting structure 41 extends along the second direction Y, and there are two second limiting structures 42, which are respectively disposed on both sides of the first limiting structure 41 along the second direction Y. The second direction Y is perpendicular to the first direction X and parallel to the width direction of the mounting plate 1, the housing 2, and the circuit board 3.

[0081] In this embodiment, two second limiting structures 42 are spaced apart on both sides of the first limiting structure 41 along the second direction, providing suitable space for the arrangement and limiting of the Type-C interface 31 of the circuit board 3, and increasing the contact points with the circuit board 3 through the distributed limiting arrangement, thereby enabling the limiting of a larger area of ​​the circuit board 3.

[0082] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the edge of the mounting plate 1 has a first support structure 11 recessed inward along the first direction X, and the first support structure 11 is disposed below the second limiting structure 42.

[0083] A second support structure 21 is provided at the position corresponding to the first support structure 11 in the housing 2. The end face of the first support structure 11 is configured to abut against the end face of the second support structure 21 to form a support space surrounding the Type-C interface 31 of the circuit board 3.

[0084] The first support structure 11 is not limited to being formed below the second limiting structure 42 and connected to the limiting base of the second limiting structure 42. The contours of the concave surfaces of the first support structure 11 and the second support structure 21 match the outer contour of the Type-C interface 31.

[0085] In this embodiment, by setting the first support structure 11 and the second support structure 21 to form a support space around the Type-C interface 31, the force during the insertion and removal process can be distributed, providing more stable and reliable support for the Type-C interface 31.

[0086] refer to Figure 1 In some embodiments, the circuit board assembly further includes a sealing ring 5, which wraps around the outer periphery of the Type-C interface 31 of the circuit board 3. The sealing ring 5 engages with the inner walls of the first support structure 11 and the second support structure 21. The sealing ring 5 includes, but is not limited to, a waterproof rubber ring.

[0087] Commercial water heater control terminals are usually installed indoors or inside the unit. In southern China, if the touch screen has poor moisture resistance, it will not meet the requirements. In humid weather, moisture can easily enter the PCB, causing the touch screen to malfunction.

[0088] In this embodiment, a sealing ring 5 is provided to wrap around the Type-C interface 31 and engage with the first support structure 11 and the second support structure 21. The first support structure 11 and the second support structure 21 can press the sealing ring 5 to prevent moisture from entering, thereby improving the waterproof and moisture-proof performance of the circuit board assembly and ensuring the reliability of the circuit assembly.

Figure 6 The cross-sectional position and Figure 1 The position of the BB section corresponds to the reference. Figures 1-4 , Figure 6 In some embodiments, the mounting plate 1 has a first mounting post 12 that protrudes from the plate body of the mounting plate 1 and is hollow, and the housing 2 has a hollow second mounting post 22 at a position corresponding to the first mounting post 12. The first mounting post 12 and the second mounting post 22 are disposed near the edge of the circuit board 3.

[0090] The circuit board assembly also includes a first connector 6, which is configured to pass through a first mounting post 12 and a second mounting post 22 along a first direction X to connect the mounting plate 1 and the housing 2.

[0091] The edge of the circuit board 3 has a first recess 33 and a second recess 34. A first mounting post 12 is disposed near the first recess 33, and a second mounting post 22 is disposed near the second recess 34. The first mounting post 12 and the second mounting post 22 may be, but are not limited to, screw posts, and the first connector 6 may be, but is not limited to, a screw. The shape of the first mounting post 12 and the second mounting post 22 may be adjusted according to the shape of the edge recess of the circuit board 3 so that the first mounting post 12 can engage with the first recess 33.

[0092] The first mounting post 12 and the second mounting post 22 extend along the first direction. The first connector 6 passes through the first mounting post 12 and the second mounting post 22 to connect the mounting plate 1 and the housing 2. The circular end face of the first mounting post 12 and the circular end face of the second mounting post 22 abut against each other.

[0093] In this embodiment, by setting the first connector 6, the first mounting post 12 and the second mounting post 22, the mounting plate 1 and the housing 2 can be detachably connected, and the accuracy and structural strength of the mating of the mounting plate 1 and the housing 2 are improved, so that the circuit board structure has a higher resistance to deformation and is not easily damaged.

The limiting rib 23 may be, but is not limited to, semi-arc-shaped, and can prevent the conformal adhesive on the circuit board 3 from being scratched off when it abuts against the circuit board 3 at the first recess 33.

[0095] In this embodiment, the limiting rib 23 protrudes outward relative to the end face of the second mounting post 22 along the first direction. When the mounting plate 1 and the housing 2 are connected, the limiting rib 23 can at least partially wrap around the side of the first mounting post 12 to improve the support strength of the first mounting post 12. The limiting rib 23 can also abut against the circuit board 3 to press the circuit board 3 to restrict the movement of the circuit board 3 along the first direction, which helps to reduce the risk of displacement and shaking of the circuit board 3 and improve the structural reliability of the circuit board assembly.

The second limiting part 432 includes, but is not limited to, restricting the movement of the circuit board 3 in the vertical direction and / or the second direction.

[0099] The number and arrangement of the third limiting structures 43 can be adjusted according to the edge shape of the circuit board 3. The width spacing between the first limiting part 431 and the second limiting part 432 along the first direction is equal to the thickness of the circuit board 3, which is approximately 1.6 mm.

[0100] In this embodiment, by setting the third limiting structure 43, the displacement of the circuit board 3 in various directions can be restricted at the edge of the circuit board 3, and the circuit board 3 can be kept in multiple directions to prevent unnecessary movement or shaking of the circuit board 3, and to ensure that the connection between the circuit board 3 and other components is stable and reliable.

[0101] refer to Figures 1-3 In some embodiments, the limiting component further includes a fourth limiting structure 44, which is disposed along the edge of the circuit board 3. The fourth limiting structure 44 includes a third limiting portion 441 and a fourth limiting portion 442.

[0102] The width of the third limiting part 441 along the first direction X is greater than the width of the circuit board 3.

The third limiting part 441 limits the circumferential movement of the circuit board 3, and the fourth limiting part 442 limits the displacement of the circuit board 3 along the first direction on the side of the circuit board 3 near the housing 2.

[0105] In this embodiment, the fourth limiting structure 44 abuts the circuit board 3 against the mounting plate 1, restricting the movement of the circuit board 3 in all directions, and can cooperate with the third limiting structure 43 to restrict the circuit board 3 from swaying towards the mounting plate 1 or the housing 2 along the thickness direction, thereby forming a stable and reliable limiting of the circuit board 3 and reducing the risk of the circuit board 3 becoming loose.
