Description
Technical Field
[0001] This utility model relates to the field of circuit board technology, and in particular to an enhanced double-sided circuit board. Background Technology
[0002] A double-sided circuit board is a printed circuit board with conductive copper layers on both sides. The circuits on both sides are connected by through holes, which allows for more complex circuit layouts in a limited space without significantly increasing the size of the circuit board.
[0003] For example, CN209676591U discloses an antistatic ultra-thin double-sided circuit board, which includes a circuit board body. The circuit board body includes a first plate, a spacer layer and a second plate. The first plate is located on the upper surface of the circuit board body, the second plate is located on the bottom surface of the circuit board body, the spacer layer is located inside the circuit board body and is located between the first plate and the second plate. The upper surface of the first plate is provided with fixing points, and the interior of the spacer layer is provided with several through holes.
[0004] In the existing technology, since double-sided circuit boards have circuits on both sides, their external protection is weak. During installation and use, they are easily scratched by external objects, which can cause deformation and breakage, resulting in damage to the circuit board. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the prior art that the outer surface of the circuit board is easily scratched by external forces during installation and use, resulting in deformation and breakage, which damages the circuit board. Therefore, an enhanced double-sided circuit board is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an enhanced double-sided circuit board, comprising a circuit board body, with protective frames on both sides of the circuit board body, a reinforcing mechanism installed on the inner side of the protective frame, and a protective mechanism installed on one side of the protective frame. The protective mechanism includes a positioning frame, one end of which is fixedly connected to one side of the circuit board body. Positioning slots are provided on both sides of the positioning frame, and positioning blocks are inserted into the interior of the positioning slots. A rotating rod is fixedly connected to one end of the positioning block, and a connecting block is rotatably connected to one end of the rotating rod.
[0007] Preferably, the positioning frame and the connecting block correspond one-to-one. The positioning frame is set at the four corners on both sides of the circuit board body, and the connecting block is set at the four corners on one side of the protective frame.
[0008] Preferably, a mounting block is fixedly connected to one side of each of the two rotating rods, and a compression spring is installed on the outside of the two mounting blocks.
[0009] Preferably, one end of the connecting block is fixedly connected to one side of the protective frame.
[0010] Preferably, the reinforcing mechanism includes anti-deformation rods, the ends of which are fixedly connected to the inner side of the protective frame, and reinforcing frames are installed between each pair of anti-deformation rods.
[0011] Preferably, a first heat dissipation fin is fixedly connected to one side of the anti-deformation rod, and one end of the first heat dissipation fin abuts against one side of the circuit board body.
[0012] Preferably, a second heat dissipation fin is fixedly connected to one side of the protective frame, and one end of the second heat dissipation fin abuts against one side of the circuit board body.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by inserting the positioning blocks into the interior of the positioning frame, the two positioning blocks are pressed towards the middle, the compression spring is compressed and deformed, and the elastic force of the compression spring pushes the two positioning blocks to insert through the interior of the positioning groove, thereby fixing the protective frame on the outside of the circuit board body. This can provide mechanical protection for both sides of the circuit board body, preventing it from being deformed, scratched or damaged by external forces such as collision, friction, and squeezing, thus ensuring the integrity and performance stability of the circuit board body.
[0015] 2. In this utility model, multiple anti-deformation rods can isolate the circuit board body from the outside world and protect the circuit board body. The anti-deformation rods are connected by a reinforcing frame, which can increase the overall strength and make the circuit board body have higher hardness and toughness, making it less prone to deformation and breakage. Through the setting of the first heat dissipation fin and the second heat dissipation fin, the heat generated by the electronic components can be quickly dissipated, preventing the circuit board body from degrading in performance or shortening its lifespan due to overheating.

Detailed Implementation
[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an enhanced double-sided circuit board, including a circuit board body 1. Protective frames 2 are provided on both sides of the circuit board body 1. A reinforcing mechanism 4 is installed inside the protective frame 2, and a protective mechanism 3 is installed on one side of the protective frame 2. The protective mechanism 3 includes a positioning frame 31. One end of the positioning frame 31 is fixedly connected to one side of the circuit board body 1. Positioning grooves 32 are provided on both sides of the positioning frame 31. Positioning blocks 33 are inserted into the interior of the positioning grooves 32. A rotating rod 34 is fixedly connected to one end of the positioning block 33, and a connecting block 35 is rotatably connected to one end of the rotating rod 34. The positioning frame 31 and the connecting block 35 correspond one-to-one. The positioning frame 31 is located at the four corners on both sides of the circuit board body 1, and the connecting block 35 is located at the four corners on one side of the protective frame 2. Mounting blocks 37 are fixedly connected to one side of each of the two rotating rods 34, and compression springs 36 are installed on the outside of the two mounting blocks 37. One end of the connecting block 35 is fixedly connected to one side of the protective frame 2.
[0024] By inserting the positioning block 33 into the interior of the positioning frame 31, the two sides of the positioning frame 31 press the two positioning blocks 33 towards the middle, the rotating rod 34 rotates at one end of the connecting block 35, and the compression spring 36 is compressed and deformed until the positioning block 33 contacts the positioning groove 32. The elastic force of the compression spring 36 pushes the two positioning blocks 33 to insert through the interior of the positioning groove 32, thereby fixing the protective frame 2 on the outside of the circuit board body 1. This can provide mechanical protection for both sides of the circuit board body 1, preventing it from being deformed, scratched or damaged by external forces such as collision, friction, and squeezing, thus ensuring the integrity and performance stability of the circuit board body 1.
[0025] Example 2: Figure 1 and Figure 3 As shown, the reinforcing mechanism 4 includes an anti-deformation rod 44, the end of which is fixedly connected to the inner side of the protective frame 2, and a reinforcing frame 43 is installed between each pair of anti-deformation rods 44; a first heat dissipation fin 41 is fixedly connected to one side of the anti-deformation rod 44, and one end of the first heat dissipation fin 41 abuts against one side of the circuit board body 1; a second heat dissipation fin 42 is fixedly connected to one side of the protective frame 2, and one end of the second heat dissipation fin 42 abuts against one side of the circuit board body 1.
[0026] The overall effect of this embodiment is that multiple anti-deformation rods 44 are installed on the inner side of the protective frame 2, which can isolate the circuit board body 1 from the outside world and protect the circuit board body 1. Furthermore, the anti-deformation rods 44 are connected by a reinforcing frame 43, which can increase the overall strength and make the circuit board body 1 have higher hardness and toughness, making it less prone to deformation and breakage. Through the setting of the first heat dissipation fin 41 and the second heat dissipation fin 42, the heat generated by the electronic components can be quickly dissipated, preventing the circuit board body 1 from degrading in performance or shortening its lifespan due to overheating.
[0027] The usage method and working principle of this device are as follows: By inserting the positioning block 33 into the interior of the positioning frame 31, the two sides of the positioning frame 31 press the two positioning blocks 33 towards the middle, the compression spring 36 is compressed and deformed, and the elastic force of the compression spring 36 pushes the two positioning blocks 33 to insert through the interior of the positioning groove 32, thereby fixing the protective frame 2 on the outside of the circuit board body 1, which can provide mechanical protection for both sides of the circuit board body 1. Through multiple anti-deformation rods 44, the circuit board body 1 is isolated from the outside world. By connecting the anti-deformation rods 44 through the reinforcing frame 43, the overall strength can be increased. The setting of the first heat dissipation fin 41 and the second heat dissipation fin 42 can quickly dissipate the heat generated by the electronic components.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
