Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board technology, and in particular to a limiting structure for PCB circuit boards and a PCB circuit board. Background Technology

[0002] PCB, or Printed Circuit Board, is a crucial component of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weaponry, utilizes PCBs to ensure electrical interconnection between integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual function of conductive traces and an insulating base.

[0003] Referring to the patent document with application number "CN202122541018.0" entitled "A PCB Circuit Board with Limiting Structure", this patent document sets up a fixed seat, a mounting plate, a telescopic rod and a spring. When the circuit board is subjected to vibration or collision, the two fixed seats squeeze the telescopic rod and the spring. The rebound force of the spring can provide cushioning for the fixed seats, thereby relieving the impact force on the circuit board and protecting the circuit board.

[0004] Existing technologies for protecting circuit boards lack a protective structure on top, making them susceptible to impacts from sharp objects. This damages the circuit board surface and affects its usability. Furthermore, existing technologies lack a restraining structure on the sidewalls. When impacted, the circuit board can shift left and right within the mounting bracket and detach from the original device due to varying impact points, thus affecting its usability.

[0005] To this end, we designed a limiting structure for PCB circuit boards and a PCB circuit board. Utility Model Content

[0006] The purpose of this utility model is to provide a limiting structure for PCB circuit boards and a PCB circuit board in order to solve the problem of imperfect protection structures in existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A limiting structure for a PCB circuit board includes a frame, a support disposed inside the frame, a first rubber body symmetrically disposed at the bottom of the support, and an anti-collision body symmetrically disposed at the top of the frame, and further includes;

[0009] The anti-collision assembly includes a second rubber body disposed at one end of the anti-collision body away from the frame, a support plate disposed on the side wall of the second rubber body, and an anti-collision plate disposed on the anti-collision body;

[0010] Elastic components are disposed on both sides of the frame and are used to connect the anti-collision body to the frame.

[0011] Preferably, the elastic component includes a plurality of first compression springs disposed at the end of the anti-collision body away from the second rubber body, an elastic disc disposed at the bottom of the anti-collision body, a second compression spring fixedly connected to the bottom of the elastic disc, and limiting components disposed on both sides of the anti-collision body.

[0012] Preferably, the limiting component includes a slide rail disposed on the side wall of the crash barrier, a first limiting plate symmetrically disposed on the outer wall of the frame, a limiting body disposed on the first limiting plate near the end of the crash barrier, and a rubber corner disposed on the side of the first limiting plate away from the bottom of the limiting body.

[0013] Preferably, the frame is provided with a bonding component, which includes a second limiting plate symmetrically arranged on the side wall of the first limiting plate, a sliding groove arranged on the side wall of the frame, a sliding post arranged in the sliding groove, and a first limiting block arranged at the end of the sliding post away from the first limiting plate.

[0014] Preferably, the first limiting plate is provided with a fixing component, which includes a second limiting block disposed at the end of the first limiting plate away from the limiting body, a pin disposed on the second limiting block, and a third limiting block disposed on the side wall of the frame.

[0015] Preferably, the frame is provided with a stabilizing component, which includes a shaft disposed on the side wall of the frame and a fixed angle rotatably connected to the shaft.

[0016] This application also discloses a PCB circuit board, including a limiting structure for a PCB circuit board as described in any of the above claims. The frame is provided with a circuit board assembly, which includes a circuit board body disposed on a support and connecting bases symmetrically disposed on the circuit board body.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting up a crash plate and a second rubber body, the top space of the circuit board body is effectively sealed when the circuit board body is placed in the frame, which can reduce the impact of sharp objects on the circuit board body. At the same time, the first rubber body and the support plate can effectively absorb the impact force and cause the sharp object to deflect after the impact, reducing the puncture phenomenon of the sharp object. Compared with the prior art, it can effectively improve the protection strength of the top of the circuit board body, thereby improving the use effect of the circuit board.

[0019] 2. With the setting of the first limiting plate and the second limiting plate, when the anti-collision plate is hit by an object, the first limiting plate can effectively resist the side impact generated by the object. At the same time, after the side impact comes into contact with the second limiting plate, it can effectively prevent the circuit board body from shifting to the left or right, further improving the stability of the circuit board body during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5A limiting structure for PCB circuit boards includes a frame 1, a support disposed inside the frame 1, a first rubber body 101 symmetrically disposed at the bottom of the support, and an anti-collision body 2 symmetrically disposed at the top of the frame 1. It also includes an anti-collision component and an elastic component. The anti-collision component mainly encloses the top of the frame 1 to increase the anti-collision area of ​​the top of the frame 1 and further improve the anti-collision effect. The elastic component mainly achieves a rebound mechanism by absorbing the impact force through its own elasticity after the anti-collision component is impacted, thereby reducing the impact force.

[0028] Before using the frame 1, it is necessary to check whether the support inside the frame 1 meets the load-bearing requirements, and whether the two first rubber bodies 101 at the bottom of the support are in a tight state so that the support can also achieve a mitigation effect after being impacted. When the anti-collision body 2 at the top of the frame 1 is impacted, the impact component will contact the anti-collision component, and with the cooperation of the anti-collision component and the elastic component, the impact component will be bounced to both sides of the frame 1, reducing the phenomenon of secondary impact of the impact component, and reducing the impact of residual force on the frame 1 and the anti-collision body 2.

[0029] It should be noted that the first rubber body 101 is solid rubber and is embedded in the gap between the support and the frame 1. The support is a spring bracket of the prior art, which can absorb the force after being impacted.

[0030] Specifically, the anti-collision component includes a second rubber body 201 disposed at one end of the anti-collision body 2 away from the frame 1, a support plate 202 disposed on the side wall of the second rubber body 201, and an anti-collision plate 203 disposed on the anti-collision body 2.

[0031] When the crash barrier is hit by a sharp object, the crash barrier 203 flips downwards under the support of the support plate 202. At the same time, the force is transmitted to the second rubber body 201 through the support plate 202. Through the elasticity of the second rubber body 201 and the support of the crash barrier 2, the impact angle of the sharp object can be effectively reduced, thus forming a rebound trend. This forces the sharp object to bounce around the frame 1, thereby further improving the protection effect of the top space of the frame 1.

[0032] Furthermore, elastic components are disposed on both sides of the frame 1 for connecting the anti-collision body 2 and the frame 1; the elastic components include several first compression springs 204 disposed at the end of the anti-collision body 2 away from the second rubber body 201, an elastic disc 6 disposed at the bottom of the anti-collision body 2, a second compression spring 601 fixedly connected to the bottom of the elastic disc 6, and limiting components disposed on both sides of the anti-collision body 2.

[0033] The limiting components include a slide rail 205 disposed on the side wall of the crash barrier 2, a first limiting plate 3 symmetrically disposed on the outer wall of the frame 1, a limiting body 302 disposed on one end of the first limiting plate 3 near the crash barrier 2, and a rubber corner 303 disposed on the side of the first limiting plate 3 away from the bottom of the limiting body 302.

[0034] When the anti-collision body 2 is impacted, the anti-collision body 2 will extend the force in the opposite direction and transmit the force to the frame 1 through the first compression spring 204. Then, under the rebound of the first compression spring 204, part of the force is absorbed, and the force is reduced by itself. At the same time, the second compression spring 601 at the bottom of the anti-collision body 2 is limited by the elastic disc 6. Since the second compression spring 601 is long, it can reduce the transmission of force through the long body after being impacted, thereby achieving the effect of dispersing the impact force.

[0035] When the anti-collision body 2 is impacted, the first limiting plates 3 on both sides can effectively reduce the lateral displacement of the anti-collision body 2, and at the same time correct the direction of the anti-collision body 2 during its descent. In addition, the slide rail 205 on the side wall of the anti-collision body 2 moves downward according to the limiting body 302 on the first limiting plate 3, and stops when it reaches the rubber corner 303.

[0036] It should be noted that the rubber corner 303 is fixed to the first limiting plate 3 by fasteners, and its height is flush with the top of the frame 1, in order to limit the descent distance of the anti-collision body 2;

[0037] The limiting body 302 is adapted to the slide rail 205, and the slide rail 205 wraps around the limiting body 302 to achieve the effect of limiting the sliding.

[0038] Furthermore, the frame 1 is provided with a bonding assembly, which includes a second limiting plate 4 symmetrically arranged on the side wall of the first limiting plate 3, a sliding groove arranged on the side wall of the frame 1, a sliding post 401 arranged in the sliding groove, and a first limiting block 402 arranged at the end of the sliding post 401 away from the first limiting plate 3.

[0039] The first limiting plate 3 is provided with a fixing component, which includes a second limiting block 304 disposed at the end of the first limiting plate 3 away from the limiting body 302, a pin 305 disposed on the second limiting block 304, and a third limiting block 5 disposed on the side wall of the frame 1.

[0040] To improve the confinement effect within the frame 1, the second confinement plate 4 increases the fit against the outer wall of the frame 1, further enhancing the protection of the circuit board assembly within the frame 1. When the circuit board assembly is impacted, the second confinement plate 4 effectively prevents the circuit board assembly from shifting left or right under the impact. Compared to the unprotected state of existing technology, this further improves the confinement effect of the circuit board assembly within the frame 1, reducing the phenomenon of the circuit board assembly detaching from the equipment. When placing the circuit board assembly within the frame 1, the second confinement plate 4 can be moved on the slide post 401 by moving it. The first limiting block 402 at the end raises the space on the side wall of the frame 1, making it easier to put the circuit board assembly into the frame 1. When the circuit board assembly cannot be put in by adjusting the second limiting plate 4, the third limiting block 5 and the pin 305 on the second limiting block 304 can be pulled out. When pulling out the pin 305, it is necessary to ensure that the bolt 501 on the third limiting block 5 will not fall off. Then the first limiting plate 3 can be peeled outward to raise the space on the side wall of the frame 1 so that the circuit board assembly can be put into the frame 1. The position of the second limiting plate 4 can be seen through the hole 301 opened on the side wall of the first limiting plate 3.

[0041] Furthermore, the frame 1 is provided with a stabilizing component, which includes a shaft 103 disposed on the side wall of the frame 1 and a fixed angle 102 rotatably connected to the shaft 103.

[0042] The frame 1 can increase the coefficient of friction through the fixed angles 102 on both sides, reducing the displacement of the frame 1 caused by impact, which would cause the circuit board assembly to detach from the device. The current angle of the fixed angles 102 can be adjusted through the shaft 103 to adapt to more scenarios.

[0043] A PCB circuit board includes a limiting structure for the PCB circuit board in any of the above embodiments. The frame 1 is provided with a circuit board assembly. The circuit board assembly includes a circuit board body 7 disposed on a support and a connecting base 701 symmetrically disposed on the circuit board body 7.

[0044] The circuit board body 7 is positioned above the support, and the connecting base 701 at the top of the circuit board body 7 is fixedly connected to the bottom end of the second compression spring 601. This improves the support force of the anti-collision body 2 and also prevents the circuit board body 7 from being damaged by impact. The circuit board body 7 is pressed against the second limiting plates 4 on both sides.

[0045] The working principle of this utility model is as follows:

[0046] When the crash barrier 2 is struck by a sharp object, the object lands near the center of the crash barrier 203. Supported by the support plate 202 and the second rubber body 201, the crash barrier 203 transmits the impact force to the first compression springs 204 on both sides of the crash barrier 2. During the downward compression of the first compression springs 204, part of the force is transmitted to the frame 1, and then from the frame 1 to the surface it is on. Simultaneously, when the crash barrier 2 is struck, part of the force is also transmitted to the second compression spring 601. Because the second compression spring 601 is relatively long, the force... The impact of the sharp object onto the circuit board body 7 is cushioned by the second compression spring 601, reducing the force of the impact. The sharp object then rebounds under the elasticity of the second rubber body 201, preventing secondary injury. When the sharp object lands on the side wall of the anti-collision plate 203, the impact force causes the circuit board body 7 to shake. The fit between the second limiting plate 4 and the circuit board body 7 effectively reduces the lateral swaying of the circuit board body 7 upon impact, further strengthening the connection between the circuit board body 7 and external devices, thereby improving the usability of the circuit board body 7. Through the installation of the anti-collision plate 203 and the second rubber body 201, when the circuit board body 7 is placed within the frame, the top space of the circuit board body 7 is effectively sealed, further reducing the impact of sharp objects on the circuit board body 7.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
