Description

Technical Field

[0001] This utility model relates to the field of long board circuit board technology, and in particular to a spliced ​​long board circuit board. Background Technology

[0002] As electronic devices evolve towards higher integration and greater multifunctionality, the size requirements for printed circuit boards (PCBs) are increasing. Traditional long PCBs (such as large PCBs exceeding 1 meter in length) are widely used in industrial control, aerospace, and communication base stations. However, the splicing structure of traditional long PCBs still has the following problems:

[0003] Currently, the splicing of long circuit boards mostly relies on bolts to connect them end to end. However, this results in the circuit boards being stacked on top of each other at the connection point, making it difficult to achieve a flat connection. This leads to an uneven surface on the spliced ​​circuit board, affecting the connection of the circuits on the surface. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a spliced ​​long board circuit board, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a splicing long board circuit board, including a circuit board module. A first pair of splicing flanges is fixedly connected to the bottom of one side edge of the circuit board module, and a second pair of splicing flanges is fixedly connected to the top of the other side edge of the circuit board module. The thickness of both the first and second pairs of splicing flanges is half the thickness of the circuit board module. Connecting holes are formed in the middle of both sides of the surface of the second pair of splicing flanges. Dating components are fixedly connected to the middle of both sides of the surface of the first pair of splicing flanges. Threaded holes are formed at positions corresponding to the centers of the two dating components on the surface of the first pair of splicing flanges. The dating components include... The device includes clamping springs arranged in a ring around the center of a threaded hole. Each clamping spring has a beveled clamp fixedly connected to the top of its outer wall. The top and bottom of the beveled clamp's outer side are provided with guide bevels. Each clamping spring has a blocking flange fixedly connected to its top inner side. The diameter of the outer side of the clamping springs is matched to the diameter of the inner wall of the connecting hole. The distance between the bottom bevel of the beveled clamp and the top surface of the first pair of splicing flanges is matched to the thickness of the second pair of splicing flanges. A threaded post is threadedly connected to the inner wall of the threaded hole. A wrench groove is provided at the center of the bottom surface of the threaded post. The length of the threaded post is matched to the distance from the bottom surface of the blocking flange to the bottom surface of the first pair of splicing flanges.

[0006] Preferably, in any of the above solutions, the first pair of splicing flanges and the second pair of splicing flanges extend out of the circuit board module by equal lengths, and the position of the mating component corresponds to the position of the connecting hole.

[0007] The technical effect achieved by adopting the above solution is that the first pair of splicing flanges and the second pair of splicing flanges can be fully aligned, reducing the splicing gap.

[0008] Preferably, in any of the above solutions, the distance from the top surface of the first pair of splicing flanges to the top surface of the circuit board module is adapted to the thickness of the second pair of splicing flanges, and the distance from the bottom surface of the second pair of splicing flanges to the bottom surface of the circuit board module is adapted to the thickness of the first pair of splicing flanges.

[0009] The technical effect achieved by adopting the above solution is that the first pair of splicing flanges and the second pair of splicing flanges can be tightly interlocked, making the splicing points on both sides of the circuit board module flush.

[0010] Preferably, in any of the above embodiments, the clamping springs are all arc-shaped, the inner surfaces of the clamping springs coincide with the inner wall of the threaded hole, and the inclined clips are arranged in a radial annular array around the center of the threaded hole.

[0011] The technical effect achieved by adopting the above solution is that the threaded column can be smoothly pushed into the inner wall of several clamping springs, and the inclined chuck can be clamped evenly in all directions.

[0012] Preferably, in any of the above schemes, the thread distribution height on the outer surface of the threaded post is adapted to the thickness of the first pair of splicing flanges, a guide slope is provided on the edge of the top of the threaded post, and the thread of the threaded post corresponds to the inner wall of the threaded hole.

[0013] The technical effect achieved by adopting the above solution is that the top of the outer wall of the threaded column can be kept smooth, making it easy to push it between several clamping springs.

[0014] This utility model has the following advantages:

[0015] 1. This splicing long board circuit board allows several circuit board modules to be fitted together vertically via the first pair of splicing flanges and the second pair of splicing flanges. After docking, the upper and lower surfaces of the several circuit board modules are on the same plane. Furthermore, the clamping springs of the docking assembly pass through the connection holes and push the inclined clamping head to clamp the top of the connection hole, thereby achieving docking and fixing. This splicing structure is simple and convenient to operate, and the surfaces overlap and are coplanar, which facilitates circuit connection.

[0016] 2. This spliced ​​long board circuit board uses the top and bottom bevels of the beveled head to facilitate pushing into and pulling out of the connection holes, making it easy to assemble and disassemble. By screwing the threaded post into the threaded hole, the top of the threaded post can be pushed into the interior of several of the aforementioned clamping springs, thereby causing the top of the threaded post to press against the blocking flange, which in turn supports the clamping springs and prevents the clamping springs from being squeezed towards the center, thus fixing the beveled head and achieving full fixation.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 4 As shown, a splicing long board circuit board includes a circuit board module 1. A first pair of splicing flanges 2 are fixedly connected to the bottom of one side edge of the circuit board module 1, and a second pair of splicing flanges 3 are fixedly connected to the top of the other side edge of the circuit board module 1. The thickness of both the first pair of splicing flanges 2 and the second pair of splicing flanges 3 is half the thickness of the circuit board module 1. Connecting holes 4 are opened in the middle of both sides of the surface of the second pair of splicing flanges 3. Dating components 5 are fixedly connected to the middle of both sides of the surface of the first pair of splicing flanges 2. Threaded holes 6 are opened at positions corresponding to the centers of the two docking components 5 on the surface of the first pair of splicing flanges 2. The docking components 5 include a ring array distributed around the center of the threaded holes 6. The clamping spring 51 has a beveled head 52 fixedly connected to the top of the outer wall of each clamping spring 51. The top and bottom of the outer side of the beveled head 52 are provided with guide bevels. The top of the inner side of each clamping spring 51 is fixedly connected with a blocking flange 53. The diameter of the outer side of the clamping spring 51 is adapted to the diameter of the inner wall of the connecting hole 4. The distance between the bottom bevel of the beveled head 52 and the top surface of the first pair of splicing flanges 2 is adapted to the thickness of the second pair of splicing flanges 3. The inner wall of the threaded hole 6 is threaded with a threaded post 7. A wrench groove 8 is provided at the center of the bottom surface of the threaded post 7. The length of the threaded post 7 is adapted to the distance from the bottom surface of the blocking flange 53 to the bottom surface of the first pair of splicing flanges 2.

[0024] As an optional technical solution of this utility model, the first pair of splicing flanges 2 and the second pair of splicing flanges 3 extend out of the circuit board module 1 by the same length, and the position of the docking component 5 corresponds to the position of the connecting hole 4, so that the first pair of splicing flanges 2 and the second pair of splicing flanges 3 can be fully docked, reducing the splicing gap.

[0025] As an optional technical solution of this utility model, the distance from the top surface of the first pair of splicing flanges 2 to the top surface of the circuit board module 1 is adapted to the thickness of the second pair of splicing flanges 3, and the distance from the bottom surface of the second pair of splicing flanges 3 to the bottom surface of the circuit board module 1 is adapted to the thickness of the first pair of splicing flanges 2, so that the first pair of splicing flanges 2 and the second pair of splicing flanges 3 can be tightly fitted together, making the splicing points on both sides of the circuit board module 1 flush.

[0026] As an optional technical solution of this utility model, a number of clamping springs 51 are all arc-shaped, and the inner surfaces of the number of clamping springs 51 coincide with the inner wall of the threaded hole 6. A number of inclined clamps 52 are arranged in a radial annular array around the center of the threaded hole 6, so that the threaded post 7 can be smoothly pushed into the inner wall of the number of clamping springs 51, and the inclined clamps 52 can be clamped evenly in all directions.

[0027] As an optional technical solution of this utility model, the thread distribution height on the outer surface of the threaded column 7 is adapted to the thickness of the first pair of splicing flanges 2. A guide slope is provided on the edge of the top of the threaded column 7. The thread of the threaded column 7 corresponds to the inner wall of the threaded hole 6, so that the top of the outer wall of the threaded column 7 remains smooth, making it convenient to push into the space between several clamping springs 51.

[0028] The following steps are required when using this spliced ​​long board circuit board:

[0029] 1) Several circuit board modules 1 can be fitted together by the first pair of splicing flanges 2 and the second pair of splicing flanges 3, and after docking, the upper and lower surfaces of several circuit board modules 1 are on the same plane.

[0030] 2) Several clamping springs 51 of the docking component 5 pass through the connecting hole 4, and are easily guided into the connecting hole 4 by the top and bottom bevels of the beveled head 52, and the beveled head 52 is pushed to clamp the top of the connecting hole 4 to achieve docking and fixing;

[0031] 3) By screwing the threaded post 7 into the threaded hole 6, the top of the threaded post 7 can be pushed into the interior of several clamping springs 51, thereby causing the top of the threaded post 7 to press against the blocking flange 53, which in turn supports the clamping springs 51 and prevents the clamping springs 51 from being squeezed towards the center, thus fixing the inclined chuck 52 and achieving full fixation.

[0032] In summary, the first pair of splicing flanges 2 and the second pair of splicing flanges 3 allow several circuit board modules 1 to be fitted together vertically. After docking, the upper and lower surfaces of the several circuit board modules 1 are on the same plane. Furthermore, the several clamping springs 51 of the docking assembly 5 pass through the connecting holes 4 and push the inclined clips 52 to clamp the top of the connecting holes 4, thus achieving docking and fixing. This splicing structure is simple and convenient to operate, and the surfaces are overlapping and coplanar, which facilitates circuit connection. The top and bottom inclined surfaces of the inclined clips 52 facilitate pushing into and pulling out of the connecting holes 4, making disassembly and assembly convenient. The threaded post 7 is screwed into the threaded hole 6, which allows the top of the threaded post 7 to be pushed into the interior of several clamping springs 51, thereby causing the top of the threaded post 7 to press against the blocking flange 53, thus supporting the clamping springs 51 and preventing the clamping springs 51 from being squeezed towards the center, thereby fixing the inclined clips 52 and achieving full fixation.
