Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a stable circuit board. Background Technology

[0002] With the continuous development and progress of social civilization, electrical appliances are widely used, and circuit boards are widely used in various electrical appliances. Circuit boards can be roughly divided into the following categories: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrate boards, high frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, and printed circuit boards, etc. When installing existing circuit boards, most of them are directly installed in fixed positions by screws, etc. In order to prevent the screws from damaging the surface of the circuit board, they are not tightened tightly enough. When they are hit, the circuit board will loosen and affect normal use. Therefore, we propose a stable circuit board. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stable circuit board, comprising: a circuit board body, the bottom of the circuit board body being disposed inside a fixing component, and a heat dissipation component being disposed on the top of the circuit board body, the fixing component being used to reinforce the circuit board body, and the heat dissipation component being used to dissipate heat from the circuit board body.

[0005] The fixing assembly includes a base plate, a right fixing frame is fixedly connected to the top right side of the base plate, a fixing shaft is fixedly connected to the middle of the inner walls on both the front and rear sides of the right fixing frame, a rotating clamp is rotatably connected to the outer side of the fixing shaft, a third spring is provided on the outer side of the rotating clamp, two limiting posts are fixedly connected to the inner walls on both the upper and lower sides of the right fixing frame, two fixing corners are fixedly connected to the top left side of the base plate, and the left side of the circuit board body is pushed against the inside of the fixing corner.

[0006] The right fixed frame has a sliding plate inside, and several second springs are fixedly connected to the right side of the sliding plate. The other end of each second spring is fixedly connected to the inner wall of the right side of the right fixed frame.

[0007] Each fixed corner has a mounting base on its inner side, which matches the mounting holes on the circuit board body. Each mounting base has a threaded fixing bolt on its inner side.

[0008] Each fixing bolt has a first spring installed on its outer side.

[0009] The heat dissipation component includes a mounting base, a cooling fan is fixedly connected inside the mounting base, a heat pipe is provided on the right side of the cooling fan, and several heat sinks are evenly fixedly connected inside the heat pipe.

[0010] The right end of the circuit board body pushes against the left side of the sliding plate.

[0011] The contact areas between the rotating clamp, the limiting post, and the circuit board body are all covered with a rubber protective layer.

[0012] This utility model has at least the following beneficial effects:

[0013] By inserting the right end of the circuit board body into the right fixing bracket, the right end of the circuit board body simultaneously pushes against the extension of the rotating clamp and the sliding plate. At this time, the sliding plate contracts under pressure, and the rotating clamp rotates under pressure. The deeper the insertion, the greater the rotation angle of the rotating clamp, and the tighter the clamping of the circuit board body. Then, the left end of the circuit board body pushes against the fixing angle, and the mounting hole aligns downward with the mounting post. At this time, the fixing bolt is rotated to fix the left end of the circuit board body. At the same time, the first spring on the outside of the circuit board body can be subjected to the pressure brought by the rotation of the fixing bolt, and continuously releases the absorbed pressure downward, so that the circuit board body fits tightly with the mounting post, ensuring the stability of the circuit board body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 5 The present invention provides a technical solution: a stable circuit board, comprising: a circuit board body 1, the bottom of the circuit board body 1 being disposed inside a fixing component 3, and a heat dissipation component 2 being disposed on the top of the circuit board body 1, the fixing component 3 being used to reinforce the circuit board body 1, and the heat dissipation component 2 being used to dissipate heat from the circuit board body 1.

[0023] The fixing component 3 includes a base plate 304. A right fixing bracket 306 is fixedly connected to the top right side of the base plate 304. A fixing shaft 312 is fixedly connected to the middle of the inner walls on both the front and rear sides of the right fixing bracket 306. A rotating clamp 307 is rotatably connected to the outer side of the fixing shaft 312. A third spring 311 is provided on the outer side of the rotating clamp 307. Two limiting posts 308 are fixedly connected to the inner walls on both the upper and lower sides of the right fixing bracket 306. Two fixing angles 301 are fixedly connected to the top left side of the base plate 304. The left side of the circuit board body 1 is pushed against the inside of the fixing angles 301.

[0024] By inserting the right end of the circuit board body 1 into the right fixing bracket 306, the right end of the circuit board body 1 simultaneously pushes against the extension of the rotating clamp 307 and the sliding plate 309. At this time, the sliding plate 309 is compressed by pressure, and the rotating clamp 307 is rotated by pressure. The deeper the insertion, the greater the rotation angle of the rotating clamp 307, and the tighter the clamping of the circuit board body 1. Then, the left end of the circuit board body 1 is pushed against the fixing angle 301, and the mounting hole is aligned downward with the mounting post 305. At this time, the fixing bolt 303 is rotated to fix the left end of the circuit board body 1. At the same time, the first spring 302 on the outside of the circuit board body 1 can be subjected to the pressure brought by the rotation of the fixing bolt 303, and continuously releases the absorbed pressure downward, so that the circuit board body 1 and the mounting post 305 are tightly attached to each other, ensuring the stability of the circuit board body 1.

[0025] A sliding plate 309 is slidably connected inside the right fixing frame 306. Several second springs 310 are fixedly connected to the right side of the sliding plate 309. The other end of the second springs 310 is fixedly connected to various parts of the right inner wall of the right fixing frame 306. The sliding plate 309 cooperates with the second springs 310 on the right side. When the sliding plate 309 is no longer under the pressure of the circuit board body 1 pushing, the second springs 310 release the absorbed pressure, thereby pushing the circuit board body 1 out of the right fixing frame 306. At the same time, the third spring 311 on the outside of the rotating clamp 307 is reset without pressure, driving the rotating clamp 307 to reset synchronously, releasing the clamping and fixing of the circuit board body 1, which facilitates the replacement and maintenance of the circuit board body 1.

[0026] The inner side of the fixed angle 301 is provided with mounting feet 305. The mounting feet 305 match the mounting holes of the circuit board body 1. The inner side of the mounting feet 305 is threaded with fixing bolts 303. The mounting feet 305 are used to install and fix the fixing bolts 303 to fix the circuit board body 1.

[0027] Each fixing bolt 303 is provided with a first spring 302 on its outer side. The first spring 302 can continuously release the pressure absorbed by the fixing bolt 303 rotating downward, so that the circuit board body 1 and the mounting post 305 fit tightly together, ensuring the stability of the circuit board body 1.

[0028] Example 2

[0029] The heat dissipation assembly 2 includes a mounting base 204, inside which a cooling fan 203 is fixedly connected. A heat pipe 202 is provided on the right side of the cooling fan 203. Several heat sinks 201 are evenly fixedly connected inside the heat pipe 202. When the circuit board body 1 generates heat during operation, the heat is absorbed through the heat pipe 202 and conducted to the heat sinks 201. Then, the side cooling fan 203 runs, driving air circulation, thereby removing the heat absorbed by the heat sinks 201, accelerating the heat dissipation of the circuit board body 1, and ensuring the stability of the circuit board body 1 during long-term operation.

[0030] The right end of the circuit board body 1 is pushed against the left side of the sliding plate 309.

[0031] The contact areas between the rotating clamp 307, the limiting post 308 and the circuit board body 1 are all covered with a rubber protective layer. By setting the rubber protective layer, the circuit on the surface of the circuit board body 1 can be protected, ensuring the integrity of the circuit board body 1.
