Description
Technical Field
[0001] This utility model relates to the field of circuit boards, specifically to a circuit board with good heat dissipation. Background Technology
[0002] Circuit boards generate heat during operation, and if this heat is not dissipated in time, the internal temperature of the device will rise rapidly. When the temperature is too high, electronic components may fail due to overheating, thus affecting the efficiency and performance of the entire circuit. Therefore, circuit board heat dissipation plays a crucial role in modern electronic devices.
[0003] A Chinese patent authorization announcement (CN108633178A) discloses a double-layer circuit board with good heat dissipation performance, comprising a first circuit board and a second circuit board. The first and second circuit boards are arranged parallel to each other vertically and are connected by a first connecting bracket and a second connecting bracket. The first and second connecting brackets are of the same specifications and are symmetrically arranged horizontally. Each of the first and second connecting brackets has a first slot and a second slot on one side. The first and second circuit boards are respectively inserted into the first slot and the second slot and fixed with screws. The bottom of each of the first and second connecting brackets is provided with a positioning plate. The edges of the first and second circuit boards are provided with a frame, and the frame is provided with a first connecting post and a second connecting post respectively. A support post is provided between the first connecting post and the second connecting post. This design is suitable for widespread application.
[0004] The above-mentioned circuit board also has the following problems when used: the spacing between the first circuit board and the second circuit board is not adjustable, which limits the scope of application when installing the circuit board, resulting in a single applicable scenario and low applicability.
[0005] Therefore, it is necessary to invent a circuit board with good heat dissipation to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a circuit board with good heat dissipation to solve the problem mentioned in the background art that the spacing between the first and second circuit boards is not adjustable, which limits the installation of the circuit board to the size of the application scenario, resulting in a single application scenario and low applicability of the circuit board.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a circuit board with good heat dissipation, including side blocks, each of the two side blocks having a sliding cavity inside, and an upper slider and a lower slider being slidably mounted inside the sliding cavity of one side block via an adjustment component, and an upper slider and a lower slider being slidably mounted inside the sliding cavity of the other side block, the upper slider and the lower slider being limited and mounted to the side blocks via a limiting component, and a connecting block being fixedly mounted at the ends of the upper slider and the lower slider, and circuit board one and circuit board two being engaged and mounted inside the snap-fit grooves inside the multiple connecting blocks.
[0008] Preferably, the first circuit board and the second circuit board constitute the main body of the circuit board, and the first circuit board and the second circuit board are arranged parallel to each other vertically, and there is a heat dissipation gap between the first circuit board and the second circuit board to ensure that the heat dissipation space of the main body of the circuit board is large and the heat dissipation effect is better.
[0009] Preferably, the upper and lower sliders are symmetrically arranged with reference to the central axis of the side block as the axis of symmetry. When the near ends of the upper and lower sliders are joined together, they form a "C" shape. The outer walls of the upper and lower sliders are attached to the inner wall of the sliding cavity to achieve a sliding connection between the upper and lower sliders. This facilitates the adjustment of the distance between the upper and lower sliders, thereby adjusting the distance between circuit board one and circuit board two, and making the circuit board body more applicable.
[0010] Preferably, connecting blocks are fixedly installed at the protruding positions of each end of the upper and lower sliders, and the four pre-reserved snap-fit slots inside the four connecting blocks fixedly connected to the two sets of upper and lower sliders are positioned opposite each other, which facilitates the installation of circuit board one and circuit board two.
[0011] Preferably, the adjustment component includes a notch pre-set inside the side block, and a short rod is fixedly installed on the top wall of the notch, and the short rod is slidably connected to an annular groove reserved inside the lever block.
[0012] Preferably, the upper and lower end walls of the lever are attached to the inner wall of the notch to achieve a rotatable connection, and the outermost side of the lever is flush with the side of the side block.
[0013] Preferably, the adjustment assembly further includes a threaded rod fixedly sleeved inside the lever block, and the outer ring of the threaded rod is provided with two sections of threads with opposite directions. The two sections of threads on the outer ring of the threaded rod are threadedly connected to the threaded grooves reserved inside the upper and lower sliders, respectively. At the same time, the upper and lower ends of the threaded rod are flush with the top and bottom of the side block. Moving the lever block causes the threaded rod to rotate, and the upper and lower sliders, which are threadedly connected to the threaded rod, move towards each other or away from each other, thereby making the spacing between circuit board one and circuit board two adjustable.
[0014] Preferably, the limiting component includes a square limiting block that is fixedly connected to the sidewalls of the upper and lower sliders at their adjacent ends, and the limiting block and the limiting groove reserved on the side of the side block are in sliding fit to ensure that the upper slider and the lower slider do not detach from the side block during installation.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] This invention uses a toggle block to drive a threaded rod to rotate. The upper and lower sliders, which are threadedly connected to the threaded rod, move towards or away from each other within the sliding cavity. This allows the spacing between circuit board one and circuit board two to be adjusted. At the same time, the threaded connection has a self-locking property, which prevents the position of the upper and lower sliders from being limited after movement, thus avoiding subsequent changes in the spacing between circuit board one and circuit board two. This allows for maximum adjustment of the heat dissipation space without affecting actual use, ensuring heat dissipation effect and extending the service life of the components.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figure 1-4 The circuit board shown includes side blocks 3. Each of the two side blocks 3 has a sliding cavity 6. An upper slider 4 and a lower slider 5 are slidably mounted inside the sliding cavity 6 of one side block 3 via an adjusting component 9. The upper slider 4 and the lower slider 5 are slidably mounted inside the sliding cavity 6 of the other side block 3. The upper slider 4 and the lower slider 5 are positioned relative to the side block 3 via a limiting component 10. A connecting block 7 is fixedly mounted at the end of each of the upper slider 4 and the lower slider 5. Circuit board 1 and circuit board 2 are engaged in the snap-fit grooves 8 inside the multiple connecting blocks 7.
[0026] In use, the toggle block 903 drives the threaded rod 905 to rotate. The upper slider 4 and the lower slider 5, which are threadedly connected to the threaded rod 905, move towards each other or away from each other inside the sliding cavity 6. This makes the distance between circuit board 1 and circuit board 2 adjustable. At the same time, the threaded connection has a self-locking property, which prevents the position of the upper slider 4 and the lower slider 5 from being limited after movement, thus avoiding subsequent changes in the distance between circuit board 1 and circuit board 2. This allows for the maximum adjustment of the heat dissipation space without affecting actual use.
[0027] Circuit board 1 and circuit board 2 constitute the main body of the circuit board. Circuit board 1 and circuit board 2 are arranged parallel to each other vertically, and there is a heat dissipation gap between circuit board 1 and circuit board 2 to ensure that the heat dissipation space of the main body of the circuit board is maximized and the heat dissipation effect is better.
[0028] The upper slider 4 and the lower slider 5 are symmetrically arranged with reference to the central axis of the side block 3. When the near ends of the upper slider 4 and the lower slider 5 are joined together, they form a "C" shape. The outer walls of the upper slider 4 and the lower slider 5 are attached to the inner wall of the sliding cavity 6 to achieve a sliding connection between the upper and lower parts. Connecting blocks 7 are fixedly installed at the protruding positions of each end of the upper slider 4 and the lower slider 5. The four pre-reserved slots 8 inside the four connecting blocks 7 fixedly connected to the two sets of upper slider 4 and lower slider 5 are positioned opposite each other, which facilitates the adjustment of the distance between the upper slider 4 and the lower slider 5, thereby adjusting the distance between circuit board 1 and circuit board 2, making the application range of the circuit board body wider. At the same time, the adhesive bonding between circuit board 1 and circuit board 2 and the slots 8 ensures the firmness of the connection of the entire circuit board body.
[0029] To facilitate the adjustment of the spacing between circuit boards 1 and 2, the adjustment assembly 9 includes a notch 901 pre-set inside the side block 3, and a short rod 902 is fixedly installed on the top wall of the notch 901. The short rod 902 is slidably connected to the annular groove 904 reserved inside the lever block 903 to ensure the stable movement of the lever block 903. The upper and lower end walls of the lever block 903 are attached to the inner wall of the notch 901 to achieve a rotatable connection, and the outermost side of the lever block 903 is flush with the side of the side block 3. The adjustment assembly 9 also includes a threaded rod 905 fixedly sleeved inside the lever block 903, and the outer ring of the threaded rod 905 is provided with upper and lower... Two sections of threads with opposite directions are connected to the threaded grooves reserved inside the upper slider 4 and lower slider 5 respectively. At the same time, the upper and lower ends of the threaded rod 905 are flush with the top and bottom of the side block 3. When the lever 903 is turned, the threaded rod 905 is rotated, and the upper slider 4 and lower slider 5, which are threaded to the threaded rod 905, move towards each other or away from each other. This makes the spacing between circuit board 1 and circuit board 2 adjustable, which makes it easy to adjust the overall thickness of the circuit board body composed of circuit board 1 and circuit board 2, thereby maximizing the heat dissipation space.
[0030] The limiting component 10 includes a square limiting block 101 that is fixedly connected to the side walls of the upper slider 4 and the lower slider 5 at their upper and lower near ends. The limiting block 101 and the limiting groove 102 reserved on the side of the side block 3 are in sliding fit to ensure that the upper slider 4 and the lower slider 5 do not detach from the side block 3 for installation.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
