Description

Technical Field

[0001] This utility model belongs to the field of circuit board technology, specifically an inner layer interconnection circuit board. Background Technology

[0002] Circuit boards are named as follows: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board (copper etching technology), etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. When interconnecting multiple circuit boards in their inner layers, it is necessary to fix and connect the positions of multiple circuit boards. The common installation method is to use bolts to make direct contact with the board body. This can easily cause certain damage to the board body during installation, and after installation, the structure will seriously affect the heat dissipation of the board body itself, making it impossible to dissipate the heat generated by the board body, thereby reducing the service life of the board body. To address this, this application proposes an inner layer interconnection circuit board. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: an inner interconnect circuit board, comprising an outer frame and multiple boards, the top of the outer frame being an opening, and notches being provided on all four sides of the outer frame. Vertical positioning posts are fixedly installed at the four corners of the bottom of the inner wall of the outer frame. Each board has a through-hole at its four corners, and the four through-holes on each board are movably fitted onto the corresponding four positioning posts. The same number of protective pads as the board are movably fitted onto each positioning post, and each protective pad is located below the corresponding board. A docking assembly is provided between each pair of adjacent boards. The top of each of the four positioning posts has a screw groove, and a rubber collar is movably fitted onto the top of each of the four positioning posts. Bolts are inserted into each of the four rubber collars, and the bottom ends of the four bolts are threaded into the screw grooves on the top of the corresponding positioning posts.

[0004] Furthermore, a heat dissipation vent is provided at the bottom of the outer frame, and multiple heat dissipation grooves are evenly provided at the bottom of the outer frame.

[0005] Furthermore, the mating assembly includes a lower mating joint and an upper mating joint. The lower mating joint is fixedly installed at the center of the top of the corresponding plate, and the upper mating joint is fixedly installed at the center of the bottom of the corresponding plate. Several mating grooves are evenly provided on the top of the lower mating joint, and mating rods, the same number as the mating grooves and aligned one by one, are evenly and fixedly installed on the bottom of the upper mating joint. Several mating rods on the bottom of the upper mating joint can be inserted into several mating grooves on the top of the lower mating joint.

[0006] Furthermore, the protective pad includes a support pad and two rubber pads, which are located at the top and bottom of the support pad, respectively.

[0007] Furthermore, the top of the positioning post is on the same horizontal plane as the top of the outer frame, and when the bottom of the rubber collar abuts against the top of the uppermost plate, the top of the rubber collar is higher than the top of the positioning post.

[0008] Furthermore, the bottom of the four notches on the outer frame sidewall is flush with the bottom of the inner frame wall.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The four positioning posts inside the outer frame enable rapid interconnection between multiple boards, and all installed boards can dissipate heat normally, thus avoiding poor heat dissipation that could affect the lifespan of the boards. Furthermore, the protective pads and rubber collars prevent damage to the boards themselves when installing multiple boards. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-8 The present invention includes an outer frame 1 and multiple plates 3. The top of the outer frame 1 is set as an opening, and notches are opened on the four sides of the outer frame 1. Vertical positioning posts 2 are fixedly installed at the four corners of the bottom of the inner wall of the outer frame 1. Each plate 3 has a through opening 4 at its four corners, and the four through openings 4 on each plate 3 are respectively movably fitted onto the four corresponding positioning posts 2. The same number of protective pads 5 as the plate 3 are movably fitted onto each positioning post 2. Each protective pad 5 is located below the corresponding plate 3. A docking assembly 9 is provided between each pair of adjacent plates 3. The top of each of the four positioning posts 2 has a screw groove 6. A rubber collar 7 is movably fitted onto the top of each of the four positioning posts 2. Bolts 8 are inserted into each of the four rubber collars 7. The bottom ends of the four bolts 8 are respectively threaded into the screw grooves 6 on the top of the corresponding positioning posts 2.

[0023] like Figure 2 and Figure 3 As shown, a heat dissipation vent 10 is provided at the bottom of the outer frame 1, and multiple heat dissipation grooves 11 are evenly provided at the bottom of the outer frame 1. Through the heat dissipation vent 10 and multiple heat dissipation grooves 11 at the bottom of the outer frame 1, heat can be discharged from the bottom of the outer frame 1, thereby preventing the outer frame 1 from hindering the dissipation of heat after installation.

[0024] like Figure 3 and Figure 4As shown, the docking assembly 9 includes a lower docking connector 91 and an upper docking connector 92. The lower docking connector 91 is fixedly installed at the center of the top of the corresponding plate 3, and the upper docking connector 92 is fixedly installed at the center of the bottom of the corresponding plate 3. Several docking slots are evenly provided on the top of the lower docking connector 91, and docking rods are evenly and fixedly installed on the bottom of the upper docking connector 92, with the same number of docking slots and aligned one by one. Several docking rods on the bottom of the upper docking connector 92 can be inserted into several docking slots on the top of the lower docking connector 91, so that the upper docking connector 92 and the lower docking connector 91 can be accurately docked, thereby completing the interconnection between two adjacent plates 3.

[0025] like Figure 7 and Figure 8 As shown, the protective pad 5 includes a support pad 51 and two rubber pads 52. The two rubber pads 52 are located at the top and bottom of the support pad 51, respectively. The protective pad 5 can separate each two adjacent plates 3, and under the action of the two rubber pads 52 in the protective pad 5, it can play a certain protective role for the plates 3.

[0026] like Figure 2 and Figure 7 As shown, the top of the positioning post 2 and the top of the outer frame 1 are on the same horizontal plane. When the bottom of the rubber collar 7 abuts against the top of the uppermost plate 3, the top of the rubber collar 7 is higher than the top of the positioning post 2. When the bolt 8 is threaded into the screw groove 6, the bolt 8 will abut against the top of the rubber collar 7. Under the compression of the bolt 8, the rubber collar 7 will firmly abut against the top of the plate 3, thereby completing the position fixation of the plate 3. Furthermore, the rubber collar 7 will not damage the plate 3 when it compresses the plate 3.

[0027] like Figure 1 and Figure 2 As shown, the bottom of the four notches on the side wall of the outer frame 1 is flush with the bottom of the inner wall of the outer frame 1, so that the heat released by the multiple plates 3 can be smoothly discharged from the four sides of the outer frame 1.
