Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and particularly relates to an embedded circuit board. Background Art

[0002] A circuit board, also known as a printed circuit board (PCB), etc., is a support for electronic components and a carrier for electrical connection of electronic components. Its main function is to connect various electronic components through circuits, playing a role in conduction and transmission. It is a key electronic interconnection component of electronic products. An embedded circuit board refers to a circuit board designed with an embedded circuit.

[0003] There are usually two types of holes on existing circuit boards. One is a via hole for installing devices, and the other is a mounting hole for installing bolts to fasten the circuit board in the device. When assembling, reinstalling after maintenance, or replacing the circuit board, it is difficult to control the tightening force of the bolts. If tightened too tightly, it is easy to cause the circuit board to be over-pressed, resulting in cracking around the mounting holes. In severe cases, the wires may also crack, causing the circuit of the circuit board to be disconnected and unable to work properly. If tightened too loosely, the vibration generated during the operation of the device is likely to cause the bolts to loosen and fall off further, resulting in phenomena such as the circuit board falling off and hitting. Summary of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide an embedded circuit board to solve the technical problems mentioned in the above background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: An embedded circuit board, including a circuit board main body. One side of the circuit board main body is connected to a support frame through a first buffer pad, and two bearing plates are fixed inside the support frame. Tensile plates are fixed on both sides of the top of the support frame.

[0006] By adopting the above technical solution, when the bolt passes through the support frame and the circuit board main body and is tightened, the pressure generated by the bolt is borne by the support frame, avoiding the circuit board main body from being cracked. At the same time, the structural strength of the support frame is increased through the setting of the bearing plates and the tensile plates, avoiding the support frame from being bent downward under the influence of pressure and cracking the circuit board main body. At the same time, buffering is carried out through the first buffer pad to further avoid this phenomenon. Moreover, the setting of the first buffer pad can also reduce the vibration received by the circuit board main body when the device vibrates.

[0007] Further, the cross-section of the support frame is in a "C" shape.

[0008] By adopting the above technical solution, when the bolt passes through the support frame and the circuit board main body and is tightened, the pressure generated by the bolt is borne by the support frame, avoiding the circuit board main body from being cracked.

[0009] Further, the first buffer pad is made of rubber material.

[0010] By adopting the above technical solution, buffering is carried out through the first buffer pad to prevent the support frame from fracturing the circuit board, and the setting of the first buffer pad can also reduce the vibration received by the main body of the circuit board when the device vibrates.

[0011] Further, the cross-sections of the bearing plate and the tensile plate are both triangular.

[0014] By adopting the above technical solution, the wire harness interfaces are provided to facilitate the connection of electrical appliances in the device to the circuit board through the wire harness, and the cooperation with the devices is provided to facilitate the normal operation of the device.

[0015] Further, a support ring penetrates through the top of the main body of the circuit board, and a fixing plate is connected to the lower part of the outer surface of the support ring, and a second mounting hole is opened at the top of the support ring.

[0016] By adopting the above technical solution, when tightening the bolt, the support ring bears the pressure of tightening the bolt to prevent the main body of the circuit board from being fractured. At the same time, buffering is carried out through the second buffer pad to prevent the support ring from fracturing the main body of the circuit board, and the setting of the second buffer pad can also reduce the vibration received by the main body of the circuit board when the device vibrates.

[0017] Further, second buffer pads are connected to both the outer surface of the support ring and the top of the fixing plate.

[0018] By adopting the above technical solution, the setting of the second buffer pad fills the gap between the support ring and the fixing plate and the circuit board, prevents the support ring and the fixing plate from being displaced randomly, and can play a buffering role.

[0019] Further, the second buffer pad is made of rubber material.

[0020] By adopting the above technical solution, buffering is carried out through the second buffer pad to prevent the support ring from fracturing the main body of the circuit board, and the setting of the second buffer pad can also reduce the vibration received by the main body of the circuit board when the device vibrates.

[0023] Furthermore, first mounting holes are formed at the tops of both the support frame and the first buffer pad.

[0024] By adopting the above technical solution, the staff passes the bolt through the first mounting hole and the circuit board body and tightens it, thereby fastening the circuit board body to the device.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0035] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model. Embodiment 1:

[0036] An embedded circuit board, as Figure 1 and Figure 2 shown, includes a circuit board main body 1. One side of the circuit board main body 1 is connected to a support frame 2 through a first buffer pad 4. The cross-section of the support frame 2 is in a "C" shape, and the pressure generated by the bolt is borne by the support frame 2 to prevent the circuit board main body 1 from being cracked; the first buffer pad 4 is made of rubber material to prevent the support frame 2 from cracking the circuit board main body 1 and can also play a shock-absorbing effect; both the support frame 2 and the first buffer pad 4 are provided with first mounting holes 3 at the top. The bolt is passed through the first mounting hole 3 and the circuit board main body 1 and tightened to complete the fastening; two bearing plates 5 are fixed inside the support frame 2, and tensile plates 6 are fixed on both sides of the top of the support frame 2. The cross-sections of the bearing plates 5 and the tensile plates 6 are both triangular. The structural strength of the support frame 2 is increased through the arrangement of the bearing plates 5 and the tensile plates 6 to prevent the support frame 2 from being bent downward under the influence of pressure and cracking the circuit board main body 1.

[0037] Refer to Figure 1 , in the above embodiment, wiring harness interfaces 11 and devices 12 are installed on both sides of the top of the circuit board main body 1, which can form a microcircuit to facilitate the normal operation of the device. Embodiment 2:

[0038] On the basis of the above Embodiment 1, in order to facilitate the fastening of large-size circuit boards, the following settings are now made.

[0039] Refer to Figure 1 , Figure 3 and Figure 4, in the above embodiments, a support ring 7 penetrates through the top of the circuit board main body 1, and the support ring 7 bears the pressure of the tightened bolt to prevent the circuit board main body 1 from being fractured; a fixing plate 9 is connected below the outer surface of the support ring 7, and the fixing plate 9 is fixedly connected to the support ring 7 by adhesion with strong glue. The staff passes the support ring 7 through the circuit board main body 1 and pastes the fixing plate 9 at the bottom of the support ring 7 to prevent the support ring 7 from falling off; second buffer pads 10 are connected to both the outer surface of the support ring 7 and the top of the fixing plate 9 to prevent the support ring 7 from fracturing the circuit board main body 1 and to achieve a shock-absorbing effect; the second buffer pads 10 are made of rubber material. A second mounting hole 8 is formed at the top of the support ring 7, and the bolt is passed through the second mounting hole 8 and tightened.

[0040] The implementation principle of the present utility model is as follows: First, during the production of the circuit board, the staff connects the first buffer pad 4 to the circuit board main body 1 by pasting, so that the support frame 2, the bearing plate 5 and the tensile plate 6 are installed on the circuit board main body 1 to facilitate the subsequent protection of the four corners of the circuit board main body 1 by the support frame 2. If the size of the circuit board main body 1 is large and the force on the middle area of the circuit board main body 1 is large, the staff can set bolts in the middle area for fastening, and then support the middle area of the circuit board main body 1 through these bolts. The specific setting method is that the staff drills holes in the middle area of the circuit board main body 1 in advance, and pay attention to avoiding the positions of the wires and devices 12 during drilling. Subsequently, the staff passes the support ring 7 through the circuit board main body 1 and pastes the fixing plate 9 at the bottom of the support ring 7. The setting of the fixing plate 9 prevents the support ring 7 from falling off;

[0041] The staff places the circuit board main body 1 into the equipment and aligns the first mounting hole 3 and the second mounting hole 8 with the threaded holes in the equipment. Then the staff first passes the bolt through the second mounting hole 8 and screws it into the threaded hole in the equipment. At this time, the support ring 7 bears the pressure from the tightened bolt to prevent the circuit board main body 1 from being fractured by the bolt. Then the staff passes the bolt through the first mounting hole 3 and the circuit board main body 1 and screws it into the threaded hole in the equipment. At this time, the pressure generated by the bolt is borne by the support frame 2 to prevent the circuit board main body 1 from being fractured by the bolt. At the same time, the bearing plate 5 supports the upper part inside the support frame 2, and the tensile plate 6 pulls the top of the support frame 2 to form a triangular diagonal support and diagonal tension, thereby increasing the structural strength of the support frame 2 and preventing the top of the support frame 2 from being bent downward by the bolt pressure and fracturing the circuit board main body 1. At the same time, buffering is carried out through the first buffer pad 4 and the second buffer pad 10 to form a protection between the support frame 2 and the support ring 7 and the circuit board main body 1, further preventing the phenomenon that the support frame 2 and the support ring 7 fracture the circuit board main body 1. Moreover, the settings of the first buffer pad 4 and the second buffer pad 10 can also reduce the vibration received by the circuit board main body 1 when the equipment vibrates.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
