Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of multi - layer circuit boards, and particularly relates to a detachable multi - layer circuit board. Background Art

[0002] A multi - layer circuit board is a device that combines two or more layers of circuit boards together. It has a good circuit integration effect and a compact structure, and has been widely used. However, during use, it is not convenient to fix the circuit board in a certain position, which easily causes the circuit board to move and collide, and even damages the internal structure of the detachable multi - layer circuit board.

[0003] Generally, there are many electronic components assembled on the circuit board. The connection between layers of the multi - layer circuit board is too tight, which will cause contact and interference between the circuit boards, thus affecting the normal operation of the electronic components; the assembly density of the multi - layer circuit board is too high, which is not conducive to heat dissipation and easily causes damage to the entire circuit board. Moreover, the circuit board in the prior art is difficult to disassemble and assemble, and not easy to repair. Summary of the Utility Model

[0004] Therefore, the embodiment of the utility model provides a detachable multi - layer circuit board to solve the problem that the tight connection between layers of the multi - layer circuit board in the prior art easily causes damage to the circuit board.

[0005] To achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0006] A detachable multi - layer circuit board includes a circuit board and a protective box for protecting the circuit board.

[0007] Two support components for limiting multiple circuit boards are installed inside the protective box, and the two support components are symmetrically arranged on the left and right sides of the inner cavity of the protective box. A positioning rod for positioning the circuit board is inserted in the middle of the support component.

[0008] A box cover for closing the protective box is installed at the upper end of the protective box.

[0009] The support component includes a side plate. A plurality of layered baffles for supporting and limiting the circuit board are installed on one side of the side plate. A plurality of second positioning holes for limiting the positioning rod are processed in the middle of the layered baffle.

[0010] Furthermore, a plurality of first positioning holes are opened at the edge of the circuit board, and a retaining disc is installed at the upper end of the positioning rod.

[0011] Furthermore, T - shaped sliders for cooperating with the protective box to limit the side plate are installed at the front and rear ends of one side of the side plate.

[0012] Further, a plurality of first heat dissipation grooves for heat dissipation are formed in the middle of the plate body of the side plate.

[0013] Further, the protective box includes a box body, a semi-circular groove for limiting the box cover is machined on the upper inner wall of the box body, and a plurality of second heat dissipation grooves for heat dissipation are machined on the side walls at the left and right ends of the box body.

[0014] Further, a plurality of limiting blocks are installed in the inner cavity of the box body, and a T-shaped limiting groove for limiting the T-shaped slider is formed in the middle of the limiting block.

[0015] Further, the box cover includes a top plate, and a handle for facilitating the disassembly of the box cover is installed in the middle of the top end of the top plate.

[0016] Further, a pressing block for closing the upper end of the protective box is installed at the lower end of the top plate, and an elastic arc-shaped block for cooperating with the semi-circular groove to limit the pressing block is installed on the side wall of the pressing block.

[0017] The embodiments of the present utility model have the following advantages:

[0018] First, when disassembling the circuit board, pull the handle upward, so that the top plate drives the pressing block to move upward synchronously, the elastic arc-shaped block undergoes elastic deformation and slides out of the cavity of the semi-circular groove, thereby quickly disassembling the box cover. Then, after taking out the two support components from the inner cavity of the box body and taking out the positioning rod from the cavities of the first positioning hole and the second positioning hole, multiple circuit boards can be disassembled.

[0019] Second, through a plurality of layered baffles fixedly installed on one side of the side plate, the distance between adjacent circuit boards can be adjusted, avoiding the overly close installation between adjacent circuit boards, and increasing the distance is beneficial to heat dissipation. The heat in the inner cavity of the box body is dissipated to the outside of the box body through the first heat dissipation groove and the second heat dissipation groove, accelerating the heat dissipation efficiency of the present utility model.

Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0032] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0033] Please refer to Figures 1-5 , the present utility model provides a detachable multi-layer circuit board, including a support assembly 100 for supporting the circuit board 10. Since the heights of the electronic components installed on the upper end of the circuit board 10 are different, the distances between adjacent circuit boards 10 are different. Through the arrangement of a plurality of layered baffles 120, the distances between adjacent circuit boards 10 can be adjusted, avoiding the overly tight installation between adjacent circuit boards 10, and increasing the distance is beneficial for heat dissipation.

[0034] A plurality of first positioning holes 11 for facilitating the positioning of the circuit board 10 are opened at the edge of the circuit board 10, so that the circuit board 10 is firmly fixed inside the protection box 200.

[0035] Two support assemblies 100 for positioning a plurality of circuit boards 10 are installed inside the protection box 200, and the two support assemblies 100 are symmetrically arranged on the left and right sides of the inner cavity of the protection box 200. A positioning rod 20 for positioning the circuit board 10 is inserted in the middle of the support assembly 100. A retaining disk 21 is fixedly installed at the upper end of the positioning rod 20. The diameter of the retaining disk 21 is larger than the cavity diameter of the second positioning hole 121, so that when the support assembly 100 is taken out of the inner cavity of the protection box 200, the positioning rod 20 is not easily dropped.

[0036] When the circuit board 10 is placed between adjacent layered baffles 120, the cavities of the first positioning hole 11 and the second positioning hole 121 are aligned, and the positioning rod 20 is inserted into the cavities of the second positioning hole 121 and the first positioning hole 11, thereby locking the circuit board 10, so that the circuit board 10 remains stable inside the protection box 200. When transporting the protection box 200 equipped with the circuit board 10, the circuit board 10 will not be damaged due to mutual collision.

[0037] The support assembly 100 includes side plates 110. T-shaped sliders 111 for cooperating with the protection box 200 to position the side plates 110 are fixedly installed at the front and rear ends of one side of the side plates 110, and the T-shaped sliders 111 slide in the cavity of the T-shaped limiting groove 221. A plurality of first heat dissipation grooves 112 for heat dissipation are opened in the middle of the plate body of the side plates 110. The heat generated during the operation of the circuit board 10 is dissipated through the first heat dissipation grooves 112 and then dissipated to the outside of the protection box 200 through the second heat dissipation grooves 212.

[0038] On one side of the side plate 110, a plurality of layered baffles 120 for supporting and limiting the circuit board 10 are installed. The circuit board 10 is placed between adjacent layered baffles 120. In the middle of the layered baffle 120, a plurality of second positioning holes 121 for limiting the positioning rod 20 are processed, which facilitates the alignment of the second positioning holes 121 with the first positioning holes 11 opened at the edge of the circuit board 10.

[0039] The protection box 200 for protecting the circuit board 10 includes a box body 210. On the inner wall of the upper end of the box body 210, a semicircular groove 211 for limiting the box cover 300 is processed. On the left and right side walls of the box body 210, a plurality of second heat dissipation grooves 212 for heat dissipation are processed, which facilitates the heat inside the box body 210 to be dissipated to the outside of the box body 210 through the second heat dissipation grooves 212.

[0040] A plurality of limiting blocks 220 are fixedly installed in the inner cavity of the box body 210. In the middle of the limiting block 220, a T-shaped limiting groove 221 for limiting the T-shaped slider 111 is opened. When installing the support assembly 100 in the inner cavity of the box body 210, directly insert the two T-shaped sliders 111 into the cavity of the T-shaped limiting groove 221, so that the side plates 110 are located on the left and right sides of the inner cavity of the box body 210.

[0041] The upper end of the protection box 200 is provided with a box cover 300 for closing the protection box 200. The box cover 300 includes a top plate 310. In the middle of the top of the top plate 310, a handle 311 for facilitating the disassembly of the box cover 300 is fixedly installed.

[0042] A pressing block 320 for closing the upper end of the protection box 200 is fixedly installed at the lower end of the top plate 310, and the pressing block 320 abuts against the top end of the side plate 110, avoiding the support assembly 100 shaking in the inner cavity of the protection box 200 during the transportation of the protection box 200. An elastic arc-shaped block 321 for cooperating with the semicircular groove 211 to limit the pressing block 320 is fixedly installed on the side wall of the pressing block 320. When the top plate 310 closes the upper end of the protection box 200, the elastic arc-shaped block 321 is inserted into the cavity of the T-shaped slider 111.

[0043] When disassembling the circuit board 10, pull up the handle 311 upward, so that the top plate 310 drives the pressing block 320 to move upward synchronously. The elastic arc-shaped block 321 undergoes elastic deformation and slides out of the cavity of the semicircular groove 211, thereby disassembling the box cover 300. After taking out the two support assemblies 100 from the inner cavity of the box body 210 and taking out the positioning rod 20 from the cavities of the first positioning hole 11 and the second positioning hole 121, a plurality of circuit boards 10 can be disassembled.

[0044] Although the present utility model has been described in detail with general descriptions and specific embodiments above, modifications or improvements can be made thereto on the basis of the present utility model, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection claimed by the present utility model.
