[0001] This application relates to the field of electronic component accessories technology, and more specifically, to a circuit board with a bracket. Background Technology
[0002] Currently, PCBs (Printed Circuit Boards) are typically mounted onto equipment using brackets. However, because the bracket's sidewalls need to be secured to the equipment with screws before the PCB is installed inside the bracket, the size of the PCB that can be installed inside the bracket is relatively small, resulting in a limited PCB area and insufficient space for arranging electronic components on the PCB.
[0003] In conclusion, how to increase the area of the PCB to increase the space for arranging electronic components is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a circuit board with a support to increase the area of the circuit board and thus increase the space for arranging electronic components.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A circuit board with a support includes: a support and a circuit board body; wherein the circuit board body is mounted on the support, the support includes a screw hole for screwing in a screw, and the circuit board body has a clearance portion; along the stacking direction of the circuit board body and the support, the projection of the clearance portion is located within the projection of the support, the screw hole is located outside the projection of the clearance portion, and the peripheral sidewall of the circuit board body is closer to the peripheral sidewall of the support than the center of the clearance portion.
[0007] In some embodiments, the screw hole includes a first screw hole for fixing the apex of the bracket; the clearance portion includes a first clearance portion formed at the apex of the circuit board body, the first clearance portion being able to expose the first screw hole, and the first clearance portion having a receiving space for accommodating a screw.
[0008] In some embodiments, the first clearance portion is fan-shaped, and the extension lines of the peripheral sidewalls of the circuit board body on both sides of the first clearance portion intersect at the center of the fan shape.
[0009] In some embodiments, there are at least two first screw holes and at least two first clearance portions, and the first clearance portions correspond one-to-one with the first screw holes.
[0010] In some embodiments, the screw hole includes a second screw hole for fixing the central region of the peripheral sidewall of the bracket; the clearance portion includes a second clearance portion formed in the central region of the peripheral sidewall of the circuit board body, the second clearance portion being able to expose the second screw hole, and the second clearance portion having an accommodating space for accommodating a screw.
[0011] In some embodiments, the second clearance portion is semi-circular, and the center of the second clearance portion coincides with the center of the second screw hole; or, the second clearance portion is semi-racetrack shaped, and the center of the semi-racetrack shape coincides with the center of the second screw hole.

[0030] like Figure 1 As shown, in the prior art, the peripheral sidewall of the bracket 2 is fixed to the device by screws, so that the printed circuit board (PCB) body 1 can only be embedded inside the bracket 2, which results in a limited area of the PCB body 1 and insufficient space for the arrangement of electronic components on the PCB body 1, thereby affecting the layout of electronic components.
[0031] like Figures 2-4 As shown, the circuit board with a bracket provided in this embodiment includes a bracket 2 and a circuit board body 1. The circuit board body 1 is mounted on the bracket 2, and the bracket 2 enables the circuit board body 1 to be mounted on a corresponding device. Since the bracket 2 needs to be mounted on the device, the bracket 2 has screw holes for screws to be screwed in, so as to fix the bracket 2 to the device and realize the mounting of the bracket 2 to the corresponding device. The circuit board body 1 has a clearance portion. Along the stacking direction of the circuit board body 1 and the bracket 2, the projection of the clearance portion is located inside the projection of the bracket, and the screw holes are located outside the projection of the clearance portion. This allows the clearance portion of the circuit board body 1 to expose the screw holes of the bracket 2 after the circuit board body 1 and the bracket 2 are stacked. The peripheral sidewall of the circuit board body 1 is closer to the peripheral sidewall of the bracket 2 than the center of the clearance portion. In this way, by providing the clearance portion, the peripheral sidewall of the circuit board body 1 can be closer to the peripheral sidewall of the bracket 2, increasing the area of the circuit board body 1 that can be mounted on the bracket 2 and increasing the space on the circuit board body 1 for arranging electronic components.
[0032] It should be noted that the outer side of the clearance part is the side of the clearance part that is close to the peripheral sidewall of the circuit board body 1. The screw hole is located on the outer side of the projection of the clearance part. It can be understood that the screw hole is closer to the peripheral sidewall of the circuit board body 1 than the clearance part, so that after the circuit board body 1 and the bracket 2 are stacked, the clearance part can show the screw hole, so that the bracket 2 can be installed on the device through the screw hole.
[0033] like Figure 2 , Figure 3 , Figure 5 As shown, the screw hole includes a first screw hole 21 for fixing the top corner of the bracket 2. In order to avoid the first screw hole 21, a first avoidance part 11 is provided at the top corner of the circuit board body 1. The first avoidance part 11 can expose the first screw hole 21 and has a receiving space to accommodate the screw, so that the first avoidance part 11 can allow the screw to pass through the first screw hole 21 to install the bracket 2 on the device.
[0034] like Figure 3 As shown, the first clearance portion 11 is fan-shaped, and the extension lines of the peripheral sidewalls of the circuit board body 1 on both sides of the first clearance portion 11 intersect at the center of the fan shape. The first clearance portion 11 in the fan shape can be further close to the first screw hole 21, further increasing the area of the circuit board body 1.
[0035] In some other embodiments, the first clearance portion 11 may also be square, triangular or other shapes that can show the shape of the first screw hole 21, and this application embodiment does not limit this.
[0036] To improve the stability of the bracket 2 and the equipment installation, there are at least two first screw holes 21 and at least two first clearance parts 11, and the first clearance parts 11 correspond one-to-one with the first screw holes 21 to ensure the corresponding installation of the circuit board body 1 and the bracket 2.
[0037] For example, such as Figure 2 As shown, there are four first screw holes 21 and four first clearance parts 11, which can further ensure the stability of the bracket 2 and the equipment installation.
[0038] To further improve the stability of the installation of bracket 2 and equipment, such as Figure 2 , Figure 4 and Figure 5 As shown, a second screw hole 22 is also provided in the middle area of the peripheral sidewall of the bracket 2, and a second clearance part 12 is provided in the middle area of the peripheral sidewall of the circuit board body 1 to avoid the second screw hole 22. The second clearance part 12 can expose the second screw hole 22, and the second clearance part 12 has a receiving space to accommodate the screw, so that the second clearance part 12 can allow the screw to pass through the second screw hole 22 to install the bracket 2 on the device.
[0039] In some embodiments, the second clearance portion 12 is semi-circular, and the center of the semi-circular second clearance portion 12 coincides with the center of the second screw hole 22.
[0040] In some other embodiments, the second clearance portion 12 is semi-racetrack shaped, and the center of the circle in the semi-racetrack shape coincides with the center of the second screw hole 22. The semi-racetrack shape makes the second clearance portion 12 fit the second screw hole 22 more closely, further increasing the area of the circuit board body 1.
[0041] In some other embodiments, the second clearance portion 12 may also be square, triangular or other shapes that can show the shape of the second screw hole 22, and this application embodiment does not limit this.
[0042] To improve the stability of the bracket 2 and the equipment installation, there are at least two second screw holes 22 and at least two second clearance parts 12, and the second clearance parts 12 correspond one-to-one with the second screw holes 22 to ensure the corresponding installation of the circuit board body 1 and the bracket 2.
[0043] For example, such as Figure 2 As shown, there are four second screw holes 22 and four second clearance parts 12, which can further ensure the stability of the bracket 2 and the equipment installation.
[0044] In practice, the first clearance part 11 and the second clearance part 12 are both rounded to the peripheral wall of the circuit board body 1 to reduce the damage to workers during the installation of the circuit board body 1.
[0045] To ensure a closer fit between the support bracket 2 and the equipment, and to reduce the gap between the middle of the support bracket 2 and the equipment, thus minimizing the entry of external impurities, such as... Figure 5 As shown, a third screw hole 23 is also provided in the middle of the bracket 2. In order to avoid the third screw hole 23, as Figure 2 As shown, the circuit board body 1 has a third clearance portion 13 corresponding to the third screw hole 23. The third clearance portion 13 can display the third screw hole 23. The center of the third clearance portion 13 is consistent with the center of the third screw hole 23. The third clearance portion 13 has a accommodating space for accommodating screws, so that the third clearance portion 13 can allow the screw to pass through the third screw hole 23 to install the bracket 2 on the device.
[0046] To improve the fit between the bracket 2 and the equipment, there are at least two third screw holes 23 and at least two third clearance parts 13, and the third clearance parts 13 correspond one-to-one with the third screw holes 23.
[0047] like Figure 2As shown, the circuit board body 1 and the bracket 2 have corresponding mounting holes 14. The mounting holes 14 are used to screw in threaded fasteners to install the circuit board body 1 on the bracket 2, so as to realize the installation and fixation of the circuit board body 1 and the bracket 2.
[0048] In the installation process of the circuit board with bracket provided in this embodiment, the bracket 2 is first installed in the corresponding position of the device through the first screw hole 21, the second screw hole 22, the third screw hole 23 and screws. Then, the first clearance portion 11, the second clearance portion 12, and the third clearance portion 13 of the circuit board body 1 are respectively aligned with the first screw hole 21, the second screw hole 22, and the third screw hole 23 of the bracket 2, and the circuit board body 1 is installed on the bracket 2 through the mounting hole 14, thus completing the installation and fixing of the circuit board body 1. By providing the first clearance portion 11, the second clearance portion 12, and the third clearance portion 13, the peripheral sidewall of the circuit board body 1 can be closer to the peripheral sidewall of the bracket 2, thereby increasing the area of the circuit board body 1 and increasing the space for arranging electronic components.
[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
