Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board technology, and in particular to a quick splicing structure and modular PCB circuit board for PCB circuit boards. Background Technology

[0002] A PCB, or Printed Circuit Board, is a crucial component of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weaponry, utilizes PCBs to enable electrical interconnection between integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual function of conductive traces and an insulating base. It replaces complex wiring, enabling electrical connections between components in a circuit, simplifying the assembly and soldering of electronic products, reducing the workload of traditional wiring methods, and significantly alleviating the labor intensity of workers.

[0003] PCB circuit boards are typically composed of modular electronic modules and electronic circuits. When assembling PCB circuit boards, it is necessary to identify the connection method to ensure that existing technology can be quickly connected to the assembly components. The common connection method is manual assembly by workers, which involves connecting multiple connecting tubes at the bottom of the PCB circuit board to the assembly components. During the assembly process, the connecting tubes are prone to misalignment, resulting in tearing at the connection between the connecting tubes and the PCB circuit board. This assembly method consumes a lot of PCB circuit board costs and also reduces the assembly efficiency of PCB circuit boards.

[0004] To address this, we designed a rapid assembly structure and modular PCB circuit board for PCB circuit boards. Utility Model Content

[0005] The purpose of this invention is to address the problem of low efficiency in manual assembly of existing PCB circuit boards by proposing a rapid assembly structure and modular PCB circuit board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A quick assembly structure for PCB circuit boards includes a structural frame, an assembly plate disposed at the bottom of the structural frame, multiple connecting cones disposed on the assembly plate, and slots symmetrically disposed on the side wall of the structural frame, and further includes; A limiting component is symmetrically arranged on the side wall of the structural frame. The limiting component includes a first support body disposed on the inner wall of the structural frame, a first guide groove disposed within the first support body, a second support body disposed on the inner wall of the structural frame, a folding component disposed at the bottom of the second support body, and a second guide groove disposed within the second support body. The pressing components are symmetrically arranged on the inner wall of the structural frame and are used to splice and fix the circuit board assembly when it is pressed down. A retractable assembly is symmetrically arranged on the outer wall of the structural frame.

[0007] Preferably, the pressing assembly includes a pressing body disposed through the top of the second support.

[0008] Preferably, the folding assembly includes a storage body symmetrically arranged on the inner wall of the structural frame, a first force-bearing plate abutting against the bottom of a second support body, and telescopic columns symmetrically arranged at the bottom of the storage body.

[0009] Preferably, the pumping assembly includes a second force-bearing plate welded to the outer wall of the structural frame, an energy storage module disposed on the second force-bearing plate, a switch button disposed on the energy storage module, cylinders symmetrically disposed on the side walls of the energy storage module, and connecting fasteners fixedly disposed at the output end of the cylinders.

[0010] Preferably, the structural frame is symmetrically provided with abutments for limiting the assembly plate, and the connecting cone has a cavity.

[0011] This application also discloses a modular PCB circuit board, including the aforementioned quick assembly structure for PCB circuit boards. The structure frame is provided with a circuit board assembly, which includes a modular circuit board disposed in a first support body, a plurality of electronic modules disposed on the modular circuit board, and connecting wires adapted to the connecting cone.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a first support body and a second support body, can effectively restrict the edges of the modular circuit board when the operator needs to assemble the modular circuit board, preventing the electronic module from being worn during the sliding process. When the modular circuit board is pressed against the second guide groove, with the assistance of the pressing body, the modular circuit board moves downward with the first force plate, so that multiple connecting wires and connecting cones are spliced. Compared with the prior art, it optimizes the defects of manual splicing of modular circuit boards, and also realizes the correction function of the modular circuit board splicing process, thereby improving the splicing efficiency of modular circuit boards.

[0013] 2. With the inclusion of a storage body and a cylinder, when the first force plate is compressed by the telescopic column, the operator can use a switch button to retract the cylinder and move the storage body to one side. After the storage body is flush with the inner wall of the structural frame, the operator can press the body to further compact the modular circuit board and the assembly plate, thereby improving the splicing effect of the modular circuit board.

[0016] 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.

[0017] Reference Figures 1-6A quick assembly structure for PCB circuit boards includes a structural frame 1, an assembly plate 3 disposed at the bottom of the structural frame 1, multiple connecting cones 301 disposed on the assembly plate 3, and holes and slots symmetrically disposed on the side wall of the structural frame 1. It also includes a limiting component, a pressing component, and a pulling component. The limiting component mainly restricts the components inside the structural frame 1, allowing them to be oriented and moved under the restriction of the limiting component. The pressing component mainly moves the components inside the structural frame 1 downward with the cooperation of the limiting component. The pulling component mainly pulls the components pressed down by the pressing component out of the structural frame 1 to avoid conflict with other components. When the staff needs to assemble the components, they only need to place the components on the structural frame 1, and then place the assembly plate 3 at the bottom of the structural frame 1. At the same time, they need to ensure that the current position of the components is aligned with the assembly plate 3, and that there are no foreign objects in the connecting cone 301 on the assembly plate 3 so that they can be assembled normally. Then, they need to ensure that the holes and slots opened on both sides of the structural frame 1 are not blocked. Before entering the structural frame 1, the components need to enter the structural frame 1 under the restriction of the restriction components, and then press against the pressing components at the end of the restriction components. Then, the components are pushed down by the pressing components. During the pushing process, they will come into contact with the pulling components and dock with the assembly plate 3 under the movement of the pulling components. It should be noted that the assembly plate 3 is a plate-shaped component used for splicing PCB circuit boards in the prior art.

[0018] Specifically, the limiting components are symmetrically arranged on the side walls of the structural frame 1 to limit the orientation of the components on the structural frame 1; The limiting components include a first support 101 disposed on the inner wall of the structural frame 1, a first guide groove 102 disposed in the first support 101, a second support 4 disposed on the inner wall of the structural frame 1, a folding assembly disposed at the bottom of the second support 4, and a second guide groove 401 disposed in the second support 4. The staff member holds the component and inserts its edge into the first support 101, and pushes it inward under the guidance of the first guide groove 102. The component then reaches the second support 4 and is pressed against the structural frame 1 at the angle under the guidance of the second guide groove 401. At this point, the component is completely confined within the structural frame 1. Before proceeding to the next step, it is necessary to ensure that there is no damage to the edge and surface of the component.

[0019] The pressing components are symmetrically arranged on the inner wall of the structural frame 1, and are used to push the components on the structural frame 1 to be assembled. The pressing assembly includes a pressing body 403 that extends through the top of the second support body 4; The folding assembly includes a storage body 404 symmetrically arranged on the inner wall of the structural frame 1, a first force-bearing plate 402 abutting against the bottom of the second support body 4, and telescopic columns 405 symmetrically arranged at the bottom of the storage body 404. Then, the staff can manually apply pressure to the pressing body 403 on the second support body 4, so that the pressing body 403 pushes the component in the second guide groove 401 downward. The first force plate 402 supported at the bottom of the component will also move downward at the same time. When the first force plate 402 moves downward, the telescopic column 405 fixedly connected to its bottom will gradually shorten its length until it is completely retracted into the storage body 404 and the first force plate 402 and the storage body 404 are pressed together. Then the next operation can be carried out. It should be noted that the storage body 404 is a hollow iron box with storage function in the prior art, and the telescopic column 405 is an extension column in the prior art, which generates a contraction phenomenon through pressure until it is completely contracted.

[0020] The pull-out components are symmetrically arranged on the outer wall of the structural frame 1, and are used to pull the components on the structural frame 1; The pulling assembly includes a second force plate 5 welded to the outer wall of the structural frame 1, an energy storage module 501 disposed on the second force plate 5, a switch button 502 disposed on the energy storage module 501, cylinders 503 symmetrically disposed on the side wall of the energy storage module 501, and a connecting fastener 504 fixedly disposed at the output end of the cylinder 503. Subsequently, based on the current connection status between the component and the assembly plate 3, the staff can activate the energy storage module 501 on the second force plate 5. The switch button 502 needs to be pressed manually to cause the two cylinders 503 at the bottom of the energy storage module 501 to pull out the storage body 404. Before pulling out, it is necessary to ensure that the connecting fasteners 504 at the connection between the two cylinders 503 and the storage body 404 are in a fixed state. At the same time, it is necessary to ensure that the first force plate 402 is at the same level as the hole groove on the outer wall of the structural frame 1, thereby improving the ability of the first force plate 402, the telescopic column 405 and the storage body 404 to be pulled into the hole groove. At this time, the staff can selectively apply pressure to the pressing body 403 to improve the connection effect between the component and the assembly plate 3. It should be noted that the energy storage module 501 is an energy storage device in the prior art. The energy storage device is started by the switch button 502, which in turn drives the two cylinders 503.

[0021] The structural frame 1 is symmetrically provided with abutment strips 103 for limiting the assembly plate 3, and the connecting cone 301 has a cavity; When assembling the abutment strip 103, the staff must ensure that the abutment strip 103 is perpendicular to the second support body 4, so that the component and the assembly plate 3 to be spliced ​​are in the same position, thereby improving the splicing efficiency of the component.

[0022] A modular PCB circuit board includes a quick assembly structure for the PCB circuit board according to any one of the claims. The structure frame 1 is provided with a circuit board assembly. The circuit board assembly includes a modular circuit board 2 disposed in a first support 101, a plurality of electronic modules 201 disposed on the modular circuit board 2, and connecting wires 202 adapted to the connecting cone 301. The aforementioned component is a modular circuit board 2. During the process of the modular circuit board 2 entering the first support body 101, it is necessary to ensure that the electronic module 201 is not damaged or loose, and that the multiple connecting wires 202 at the bottom of the modular circuit board 2 are not loose. At this time, with the assistance of the pressing body 403, the connecting wires 202 are connected to the connecting cones 301 on the assembly plate 3.

[0023] The working principle of this utility model is as follows: When the worker needs to assemble the modular circuit board 2, the assembly plate 3 can be placed at the bottom of the structural frame 1 and pressed against the abutment strip 103. Then, the worker presses the two sides of the modular circuit board 2 against the first support body 101 and pushes it into the structural frame 1 through the first guide groove 102 until the modular circuit board 2 is pressed against the angle between the second support body 4 and the structural frame 1. Then, the worker manually applies pressure to the pressing body 403 to push the modular circuit board 2 in the second guide groove 401 downward. During the movement, the first force plate 402 at the bottom of the modular circuit board 2 moves downward. After the telescopic column 405 is fully retracted, the first force plate 402 is in contact with the storage body. 404 abuts against each other. Then, with the modular circuit board 2 pressed against the first force plate 402, press the switch button 502 on the energy storage module 501. This causes the two cylinders 503 at the bottom of the energy storage module 501 to pull out the storage body 404. During the pulling, the first force plate 402 enters the area of ​​the outer slot of the structural frame 1 and moves towards the cylinder 503 from the inner wall of the slot until the side wall of the first force plate 402 is parallel to the outer wall of the slot. At this time, the modular circuit board 2 can continue to move downward under the pressure of the pressing body 403, which increases the connection strength between the modular circuit board 2 and the assembly plate 3. Finally, the combination of the modular circuit board 2 and the assembly plate 3 can be manually pulled out. With the first support 101 and the second support 4 in place, when the staff needs to assemble the modular circuit board 2, the first support 101 and the second support 4 can effectively restrict the edge of the modular circuit board 2, so as to prevent the electronic module 201 from being worn during the sliding process. When the modular circuit board 2 is pressed against the second guide groove 401, with the help of the pressing body 403, the modular circuit board 2 moves downward with the first force plate 402, so that multiple connecting wires 202 and connecting cone 301 are assembled.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
