Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication equipment, and military weaponry, requires a circuit board to enable the electrical interconnection between integrated circuits and other electronic components.

[0003] Traditional circuit boards are typically designed as a single unit. During use, many modules are installed on the board, and the more modules there are, the larger the board becomes, occupying more space. When a module on the circuit board fails and needs repair, because of its unibody design, it's impossible to remove only a portion of the board; the entire board must be disassembled for repair, leading to inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a splicing circuit board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing circuit board, comprising a circuit board, characterized in that: the circuit board is provided with a splicing assembly, the splicing assembly comprising a horizontal plate, a vertical plate located below the horizontal plate, a horizontal strip A and a vertical strip fixedly disposed above the vertical plate, a horizontal strip B fixedly disposed below the horizontal plate, a plurality of screws, and a limiting assembly disposed on the horizontal plate; the horizontal plate and the vertical plate are rotatably connected and arranged in a cross shape; the horizontal strip A and the vertical strip are fixedly connected and arranged in a cross shape; the front and rear side walls of the horizontal strip A are aligned with the front and rear side walls of the horizontal strip B; and a plurality of openings are provided on the horizontal plate. The vertical plate has several through holes B, and the circuit board has several through holes A and screw holes B. After the left rear corner of the circuit board is inserted between the horizontal plate and the vertical plate, the left side wall of the circuit board abuts against the vertical bar, and the rear side wall of the circuit board abuts against the horizontal bar A and the horizontal bar B. When the left side wall of the circuit board abuts against the vertical bar, the screw hole A is aligned with the through hole A. The screw is inserted into the through hole A and screwed into the screw hole A to fix the circuit board and the horizontal plate. When the rear side wall of the circuit board abuts against the horizontal bar A and the horizontal bar B, the screw hole B is aligned with the through hole B. The screw is inserted into the through hole B and screwed into the screw hole B to fix the circuit board and the vertical plate.

[0006] Preferably, the limiting component includes a rod, a tension spring sleeved on the rod, and a disc fixedly mounted on the rod. The horizontal plate has insertion holes on the left and right sides of the vertical plate. The rod is inserted into the insertion holes and slidably connected to the horizontal plate and in contact with the vertical plate. The diameter of the disc is larger than the diameter of the insertion holes. The upper and lower ends of the tension spring are fixedly connected to the disc and the horizontal plate, respectively.

[0007] Preferably, positioning strips are fixedly provided on both the left and right sides of the circuit board, and positioning grooves matching the positioning strips are opened on both the left and right side walls of the vertical strip. After the positioning strips are inserted into the positioning grooves, the left side wall of the circuit board abuts against the vertical strip.

[0008] Preferably, an anti-detachment strip is fixedly provided on the side of the positioning strip away from the circuit board. The height of the anti-detachment strip is greater than the height of the positioning strip. Anti-detachment grooves matching the anti-detachment strip are provided on both the left and right side walls of the vertical strip. The anti-detachment strip is inserted into the anti-detachment groove and contacts and connects with the vertical strip.

[0010] Preferably, a cam is fixedly provided on both the upper and lower sides of the rotating shaft, and the diameter of the cam is larger than the diameter of the rotating shaft.

[0011] Preferably, the convex disk is located on the upper side of the horizontal plate and the lower side of the vertical plate.

[0012] The beneficial effects of this utility model are as follows: During assembly, rotating the horizontal plate makes it cross-shaped with the vertical plate. At this time, the insert rods are located on the left and right sides of the vertical plate and are in contact with it, which plays a limiting role and prevents the vertical plate from rotating. Inserting the left rear corner of the circuit board between the horizontal and vertical plates makes the positioning strip insert into the positioning groove, which plays a positioning role. At this time, the left side wall of the circuit board is in contact with the vertical strip. Pushing the circuit board all the way back along the positioning groove, the rear side wall of the circuit board is in contact with horizontal strips A and B. At this time, screw hole A is aligned with through hole A, and screw hole B is aligned with through hole B. Inserting the screw into through hole A and screwing it into screw hole A fixes the circuit board to the horizontal plate. Inserting the screw into through hole B and screwing it into screw hole B fixes the circuit board to the vertical plate. To fix the circuit board, insert the right rear corner of another circuit board between the horizontal and vertical plates, positioning it to the left of the vertical strip. The right side wall of the other circuit board will then abut against the vertical strip. Fix the other circuit board to the horizontal and vertical plates (as described above). This allows the two circuit boards to be joined together. Similarly, insert the left front corner of the third circuit board and the right front corner of the fourth circuit board between the horizontal and vertical plates, allowing up to four circuit boards to be joined together. In summary, this invention has the beneficial effect of joining multiple circuit boards together, solving the problem that when a module on a circuit board is damaged and needs repair, because the circuit board is an integral structure, it is impossible to remove only part of the circuit board; the entire circuit board must be removed for repair, which is inconvenient.

The horizontal plate 2 and the vertical plate 3 are rotatably connected and arranged in a cross shape. The horizontal bar A4 and the vertical bar 5 are fixedly connected and arranged in a cross shape. The front and rear side walls of the horizontal bar A4 are aligned with the front and rear side walls of the horizontal bar B6. The horizontal plate 2 has a plurality of screw holes A8, and the vertical plate 3 has a plurality of through holes. Hole B9, the circuit board 1 has several through holes A10 and screw holes B11. After the left rear corner of the circuit board 1 is inserted between the horizontal plate 2 and the vertical plate 3, the left side wall of the circuit board 1 abuts against the vertical bar 5, and the rear side wall of the circuit board 1 abuts against the horizontal bars A4 and B6. When the left side wall of the circuit board 1 abuts against the vertical bar 5, the screw hole A8 is aligned with the through hole A10. The screw 7 is inserted into the through hole A10 and screwed into the screw hole A8 to fix the circuit board 1 and the horizontal plate 2. When the rear side wall of the circuit board 1 abuts against the horizontal bars A4 and B6, the screw hole B11 is aligned with the through hole B9. The screw 7 is inserted into the through hole B9 and screwed into the screw hole B11 to fix the circuit board 1 and the vertical plate 3. During assembly, the horizontal plate 2 is rotated so that it and the vertical plate 3 are arranged in a cross shape. At this time, the insertion rod 12 is located on the left and right sides of the vertical plate 3 and is in contact with the vertical plate 3, which plays a limiting role and prevents the vertical plate 3 from rotating. The left rear corner of the circuit board 1 is inserted between the horizontal plate 2 and the vertical plate 3, so that the positioning strip 16 is inserted into the positioning groove 17, which plays a positioning role. At this time, the left side wall of the circuit board 1 is in contact with the vertical strip 5. The circuit board 1 is pushed all the way back along the positioning groove 17, and the rear side wall of the circuit board 1 is in contact with the horizontal strips A4 and B6. At this time, the screw hole A8 is aligned with the through hole A10, and the screw hole B11 is aligned with the through hole B9. The screw 7 is inserted into the through hole A10 and screwed into the screw hole A8 to fix the circuit board 1 to the horizontal plate 2. The screw 7 is inserted into the through hole B9 and screwed into the screw hole B11 to fix the circuit board 1 to the vertical plate 3. Connect and fix circuit board 1; insert the right rear corner of another circuit board 1 between the horizontal plate 2 and the vertical plate 3 and to the left of the vertical strip 5. The right side wall of the other circuit board 1 will abut against the vertical strip 5. Fix the other circuit board 1 to the horizontal plate 2 and the vertical plate 3 (the process is as above). The two circuit boards 1 can be spliced ​​together. Similarly, insert the left front corner of the third circuit board 1 and the right front corner of the fourth circuit board 1 between the horizontal plate 2 and the vertical strip 3. Up to four circuit boards 1 can be spliced ​​together. In summary, this utility model has the beneficial effect of splicing multiple circuit boards 1 together. It solves the problem that when a module on circuit board 1 is damaged and needs to be repaired, because circuit board 1 is an integral structure, it is not possible to remove only part of circuit board 1. The entire circuit board 1 needs to be removed for repair, which is inconvenient for repair.

[0021] Preferably, the limiting component includes a rod 12, a tension spring 13 sleeved on the rod 12, and a disc 14 fixedly mounted on the rod 12. The horizontal plate 2 has insertion holes 15 located on the left and right sides of the vertical plate 3. The rod 12 is inserted into the insertion holes 15, slidably connected to the horizontal plate 2, and in contact with the vertical plate 3. The diameter of the disc 14 is larger than the diameter of the insertion holes 15. The upper and lower ends of the tension spring 13 are fixedly connected to the disc 14 and the horizontal plate 2, respectively. Because the rod 12 is inserted into the insertion holes 15, slidably connected to the horizontal plate 2, and in contact with the vertical plate 3, it serves a limiting function, preventing the vertical plate 3 from rotating. Because the diameter of the disc 14 is larger than the diameter of the insertion holes 15, and the upper and lower ends of the tension spring 13 are fixedly connected to the disc 14 and the horizontal plate 2, it prevents the rod 12 from detaching from the insertion holes 15.

[0022] Preferably, positioning strips 16 are fixedly provided on both the left and right sides of the circuit board 1, and positioning grooves 17 matching the positioning strips 16 are provided on both the left and right side walls of the vertical strip 5. After the positioning strips 16 are inserted into the positioning grooves 17, the left side wall of the circuit board 1 abuts against the vertical strip 5. Since the positioning strips 16 abut against the vertical strip 5 after being inserted into the positioning grooves 17, they play a positioning role for the circuit board 1, facilitating the sliding of the circuit board 1.

[0023] Preferably, an anti-detachment strip 18 is fixedly installed on the side of the positioning strip 16 away from the circuit board 1. The height of the anti-detachment strip 18 is greater than the height of the positioning strip 16. Anti-detachment grooves 19 matching the anti-detachment strip 18 are opened on both the left and right side walls of the vertical strip 5. The anti-detachment strip 18 is inserted into the anti-detachment groove 19 and contacts the vertical strip 5. Because the height of the anti-detachment strip 18 is greater than the height of the positioning strip 16, the anti-detachment strip 18 is inserted into the anti-detachment groove 19 and contacts the vertical strip 5, thus preventing the positioning strip 16 from falling off.

[0024] Preferably, the horizontal plate 2 and the vertical plate 3 are rotatably connected by a pivot, which is located at the center of the horizontal plate 2 and the vertical plate 3. Since the pivot is located at the center of the horizontal plate 2 and the vertical plate 3, it facilitates the rotation of the horizontal plate 2 and the vertical plate 3.

[0025] Preferably, a convex plate 20 is fixedly provided on both the upper and lower sides of the rotating shaft, and the diameter of the convex plate 20 is larger than the diameter of the rotating shaft. Since the diameter of the convex plate 20 is larger than the diameter of the rotating shaft, it serves to prevent the rotating shaft from falling off.

[0026] Preferably, the convex plate 20 is located on the upper side of the horizontal plate 2 and the lower side of the vertical plate 3. Because the convex plate 20 is located on the upper side of the horizontal plate 2 and the lower side of the vertical plate 3, it limits the upper and lower ends of the rotating shaft.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
