It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a printed circuit board.

[0003] At present, the specifications of circuit boards are formulated and produced according to certain specifications, and there are many models with different specifications. However, it is found in actual use that the utilization rate of circuit boards is low, and it is often accompanied by waste of cutting of circuit boards. The reason is caused by the limited specifications. For this reason, we propose a circuit board that can be spliced, so that circuit boards of appropriate specifications can be spliced ​​according to the actual size of the circuit boards required. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a spliced ​​printed circuit board to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spliced ​​printed circuit board, comprising a circuit board, wherein the circuit board contains multiple groups of circuit board module units, and the multiple groups of circuit board module units are spliced ​​and connected to each other, and the bottom ends of all the circuit board module units except the last group of circuit board module units are fixed with a connecting plate, and the bottom ends of all the circuit board module units except the first group of circuit board module units are fixed with a clamping plate, the inner end surface of the connecting plate is fixedly connected with an insert plate, and the inside of the clamping plate is provided with a clamping groove that fits with the insert plate, and the insert plate is slidably connected to the inner wall of the clamping groove.

[0006] By adopting the above technical solution, the circuit boards can be connected in a modular manner, thereby being able to adapt to the usage requirements of different specifications, greatly reducing the waste of circuit boards and improving the utilization rate of circuit boards.

[0007] The utility model is further configured such that a limiting mechanism for efficiently limiting the plug plate is provided in the inner wall of the locking plate, and the limiting mechanism includes threaded walls opened in the inner walls on both sides of the locking plate, and bolts adapted to be connected to the threaded walls are connected in the threaded walls, and the bolts extend outward.

[0008] By adopting the above technical solution, the plug board can be limited.

[0009] The utility model is further configured that the top end of the bolt is fixedly connected with a driving part for driving the bolt, and the inner end surface of the bolt is located outside the threaded wall and is connected with a torsion spring shaft installed on the outer wall of the clamping plate.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model sets a circuit board module unit and a limiting mechanism. First, according to the specification requirements of the required circuit board, a suitable number of circuit board module units are selected for splicing. During splicing, the driving unit first drives the bolt to rotate in the opposite direction so that the end of the bolt overflows the engaging groove, and then the plug-in plate at the bottom end of the first group of circuit board module units is inserted into the engaging groove in the engaging plate at the bottom end of the second group of circuit board module units. Further, the reverse driving limit of the driving unit is released. At this time, the driving unit will reset under the action of the torsion spring shaft, and then drive the bolt to reset and rotate until the end of the bolt moves to the limiting hole. At this time, the limiting of the plug-in plate is completed, which ensures the stability of the plug-in plate connection, that is, the stability of the connection between the circuit board module units.

[0017] 2. The utility model provides a slide plate and a return spring. When the plug plate is inserted into the engaging groove, the plug plate will push the slide plate to move inward and cause the slide plate to squeeze the return spring, thereby realizing kinetic energy storage of the return spring. Furthermore, when disassembling the circuit board module unit in the connected state, the driving part of the bolt is rotated in the opposite direction according to the above steps, so that the bolt moves out of the limit hole, thereby releasing the engagement limit of the plug plate. At this time, the return spring will release the stored energy to reset, thereby pushing the slide plate to reset and move. The movement of the slide plate will push the plug plate to move outward, that is, push the circuit board module unit to move outward, thereby realizing the function of assisting disassembly during the disassembly process.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A spliced ​​printed circuit board, such as Figure 1-5 As shown, the circuit board 1 includes a plurality of groups of circuit board module units 2, which are spliced ​​and connected to each other, and a connecting plate 3 is fixed to the bottom ends of all the circuit board module units 2 except the last group of circuit board module units 2, and a clamping plate 4 is fixed to the bottom ends of all the circuit board module units 2 except the first group of circuit board module units 2, and an inserting plate 5 is fixedly connected to the inner end surface of the connecting plate 3, and a clamping groove 6 that fits with the inserting plate 5 is opened inside the clamping plate 4, and the inserting plate 5 is slidably connected to the inner wall of the clamping groove 6;

[0027] Furthermore, in this embodiment, a limiting mechanism for effectively limiting the position of the plug board 5 is provided in the inner wall of the clamping plate 4;

[0028] Specifically, the limiting mechanism includes a threaded wall 7 opened in the inner wall on both sides of the locking plate 4, and a bolt 8 adapted to be connected to the threaded wall 7 is connected in the threaded wall 7, and the bolt 8 extends outward, and the top end of the bolt 8 is fixedly connected to a driving part 9 for driving the bolt 8, and the inner end face of the bolt 8 is located on the outside of the threaded wall 7 and is connected to a torsion spring shaft 10 installed on the outer wall of the locking plate 4, thereby limiting the insertion plate 5.

[0029] See also Figure 4 A limiting hole 11 is provided on the outer wall of the inserting plate 5 , and the inner diameter of the limiting hole 11 is matched with the outer diameter of the bolt 8 , so as to realize the locking and limiting of the inserting plate 5 .

[0030] See also Figure 5 A slide plate 12 is provided inside the locking plate 4 and is slidably connected to the inner wall of the locking groove 6, and the inner end surface of the slide plate 12 is connected to multiple groups of return springs 13 installed on the inner wall of the locking plate 4, which can be ejected when the circuit board module unit 2 is disassembled, thereby achieving the function of auxiliary disassembly.

[0031] The working principle of the utility model is as follows: first, according to the specification requirements of the required circuit board 1, a suitable number of circuit board module units 2 are selected for splicing. When splicing, the driving unit 9 is used to drive the bolt 8 to rotate in the opposite direction so that the end of the bolt 8 moves out of the engaging groove 6, and then the plug plate 5 at the bottom end of the first group of circuit board module units 2 is inserted into the engaging groove 6 in the engaging plate 4 at the bottom end of the second group of circuit board module units 2;

[0032] Further, the reverse driving limit of the driving part 9 is released. At this time, the driving part 9 will be reset under the action of the torsion spring shaft 10, thereby driving the bolt 8 to reset and rotate until the end of the bolt 8 moves into the limiting hole 11. At this time, the limiting of the plug board 5 is completed, ensuring the stability of the connection of the plug board 5, that is, ensuring the stability of the connection between the circuit board module units 2;

[0033] In addition, when the plug board 5 is inserted into the engaging groove 6, the plug board 5 will push the slide plate 12 to move inward and cause the slide plate 12 to squeeze the reset spring 13, thereby storing the kinetic energy of the reset spring 13. Furthermore, when disassembling the circuit board module unit 2 in the connected state, the driving part 9 of the bolt 8 is rotated in the opposite direction according to the above steps, so that the bolt 8 is moved out of the limiting hole 11, thereby releasing the engaging limit of the plug board 5. At this time, the reset spring 13 will release the stored energy to reset, and then push the slide plate 12 to reset and move. The movement of the slide plate 12 will push the plug board 5 to move outward, that is, push the circuit board module unit 2 to move outward, thereby realizing the function of assisting disassembly during the process of disassembling the circuit board module unit 2.
