Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board that is easy to separate. Background Technology

[0002] A circuit board is the substrate of an electronic device, used for mechanical support and electrical connection of electronic components such as chips, resistors, and capacitors. Its core function is to realize signal transmission and power distribution between components through pre-designed conductive copper foil traces and insulating substrates.

[0003] The patent specification with announcement number CN222235133U discloses a circuit board that facilitates board separation. It includes a motherboard with multiple annular slots. A sub-circuit board is located at the center of each annular slot. A connecting block is located at the opposite end of each sub-circuit board. Each connecting block corresponds to an annular slot, and the end of each connecting block away from the sub-circuit board is connected to the inner wall of the corresponding annular slot. Grooves are formed on both sides of each connecting block near the sub-circuit board. This invention allows the connecting block to narrow towards the center on the side closest to its corresponding sub-circuit board, and the two connecting blocks are located only at positions far apart from each other on the sub-circuit boards. This allows for board separation of the circular circuit board using existing cutting-edge board separators, and only requires two straight cuts to complete the separation of an entire row of sub-circuit boards.

[0004] However, in implementing the relevant technologies, the following problems were found with the aforementioned circuit board that is easy to separate: In the current circuit board separation process, V-grooving or stamp hole design is usually used to separate the boards. However, in the manual separation process, lateral bending force needs to be applied directly to the sub-circuit boards, which can easily lead to deformation, solder joint cracking, or edge burrs due to uneven force on the sub-circuit boards. On the other hand, mechanical separation machines have limitations such as high equipment cost, complex operation, and unsuitability for small-batch production. In addition, traditional separation methods are difficult to control the fracture path accurately, which can easily damage the components or traces on the circuit board. Although there are designs in the existing technology that use pre-cut grooves or weak structures to assist in separation, they still require external tools to apply force, making it difficult to achieve fast, accurate, and low-cost tool-free separation operations. In view of this, a circuit board that is easy to separate is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board that is easy to separate into multiple boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board that is easy to separate, including a mother circuit board, a connecting block fixedly connected inside the mother circuit board, a daughter circuit board fixedly connected to the end of the connecting block away from the mother circuit board, and a socket provided inside the mother circuit board.

[0007] As a further description of the above technical solution: The inner walls of the sockets inside the bus circuit board are fixedly connected to both sides of the inner walls. A plug rod is slidably connected to the inner walls of the sockets inside the bus circuit board. The plug rod has slots on both sides. A pressing piece is fixedly connected to the top of the plug rod. A cutting piece is fixedly connected to the bottom of the pressing piece on the side away from the plug rod. The outer side of the locking piece engages with the slot. The bottom of the cutting piece contacts the top of the connecting block. When separating the sub-circuit board from the inside of the bus circuit board, the pressing piece is squeezed from top to bottom, causing the cutting piece to apply downward pressure to the connecting block between the bus circuit board and the sub-circuit board, causing the connecting block to break, thereby achieving the purpose of separating the bus circuit board and the sub-circuit board.

[0008] As a further description of the above technical solution: the motherboard has several circular through holes inside, and the connecting block and the sub-circuit board are both fixed in the circular through holes. The diameter of the circular through holes in the motherboard is larger than the diameter of the sub-circuit board, and the width between the circular through holes and the sub-circuit board matches the width of the connecting block. The motherboard and the sub-circuit board can be separated by squeezing the connecting block.

[0009] As a further description of the above technical solution: the number of the sockets is several, and the sockets are evenly distributed on the left and right sides of the sub-circuit board. The diameter of the socket is matched with the cross-sectional diameter of the plug rod, so that the plug rod can be inserted into the socket and can only slide longitudinally within the socket, avoiding lateral sliding.

[0010] As a further description of the above technical solution: the number of locking blocks on the inner wall of the socket is two sets, and the locking blocks are distributed on the left and right sides of the inner wall of the socket. The number and shape of the locking slots on the outer side of the plug rod are matched with the number and shape of the locking blocks on the inner wall of the socket. This not only plays a fixing role in the installation of the pressing piece and the cutting piece, but also prevents the pressing piece above the bottom busbar from being stressed and causing the cutting piece to break against the connecting block when the busbars are stacked.

[0011] As a further description of the above technical solution: both the cutting blade and the connecting block have curvature, and the curvature of the cutting blade is the same as that of the connecting block. The cutting blade and the connecting block are perpendicular to each other, which can avoid the situation where the sub-circuit board is easily deformed due to pressure when manually pressed.

[0012] As a further description of the above technical solution: the number of the pressing plate and the insert and cutting plate at its bottom are the same as the number of connecting blocks. The top of the pressing plate is provided with a rubber layer to facilitate the operator to apply pressure to the pressing plate when manually separating the mother circuit board and the sub-circuit board.

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a circuit board that facilitates separation. Through the design and cooperation of the cutting blade and the insertion rod, the device can separate the sub-circuit board from the mother circuit board by pressing the pressing blade from top to bottom. This causes the cutting blade to apply pressure from top to bottom to the connecting block between the mother circuit board and the sub-circuit board, causing the connecting block to break. This achieves the purpose of separating the mother circuit board and the sub-circuit board, avoiding the situation where manually pressing the sub-circuit board can easily cause it to deform due to stress. At the same time, the locking blocks set inside the insertion hole can lock into the locking grooves on the left and right sides of the insertion rod, which not only fixes the installation of the pressing blade and the cutting blade, but also prevents the pressing blade above the bottom mother circuit board from being subjected to force that could cause the cutting blade to break against the connecting block when the mother circuit boards are stacked.

[0023] Reference Figures 1 to 6The present invention provides a circuit board that is easy to separate, including a mother circuit board 1, a connecting block 4 is provided inside the mother circuit board 1 by cutting, a sub-circuit board 2 is provided at the end of the connecting block 4 away from the mother circuit board 1, and a socket 8 is opened inside the mother circuit board 1.

[0024] The inner walls of the socket 8 inside the motherboard 1 are provided with locking blocks 9 on both sides. The inner walls of the socket 8 inside the motherboard 1 are inserted and slid by the plug rod 5. The plug rod 5 has slots 6 on both sides. The top of the plug rod 5 is provided with a pressing piece 3. The bottom of the pressing piece 3 is provided with a cutting piece 7 on the side away from the plug rod 5. The outer side of the locking block 9 engages with the slot 6. The bottom of the cutting piece 7 contacts the top of the connecting block 4. When the sub-circuit board 2 is separated from the motherboard 1, the pressing piece 3 is squeezed from top to bottom, so that the cutting piece 7 applies pressure from top to bottom to the connecting block 4 connecting the motherboard 1 and the sub-circuit board 2, causing the connecting block 4 to break, thereby achieving the purpose of separating the motherboard 1 and the sub-circuit board 2.

[0025] As a further implementation of the above technical solution: the motherboard 1 has several circular through holes, and the connecting block 4 and the sub-circuit board 2 are both fixed in the circular through holes. The diameter of the circular through holes in the motherboard 1 is larger than the diameter of the sub-circuit board 2, and the width between the circular through holes and the sub-circuit board 2 matches the width of the connecting block 4. The motherboard 1 and the sub-circuit board 2 can be separated by squeezing the connecting block 4.

[0026] As a further implementation of the above technical solution: the number of sockets 8 is several, and the sockets 8 are evenly distributed on the left and right sides of the sub-circuit board 2. The diameter of the socket 8 matches the cross-sectional diameter of the plug rod 5, so that the plug rod 5 can be inserted into the socket 8 and can only slide longitudinally within the socket 8, avoiding lateral sliding.

[0027] As a further implementation of the above technical solution: there are two sets of locking blocks 9 on the inner wall of the socket 8, and the locking blocks 9 are distributed on the left and right sides of the inner wall of the socket 8. The number and shape of the locking grooves 6 on the outside of the plug rod 5 are matched with the number and shape of the locking blocks 9 on the inner wall of the socket 8. This not only fixes the installation of the pressing piece 3 and the cutting piece 7, but also prevents the pressing piece 3 above the bottom busbar 1 from being stressed and causing the cutting piece 7 to break against the connecting block 4 when the busbar 1 is stacked.

[0028] As a further implementation of the above technical solution: both the cutting blade 7 and the connecting block 4 have curvature, and the curvature of the cutting blade 7 is the same as that of the connecting block 4. The cutting blade 7 and the connecting block 4 are perpendicular to each other, which can avoid the situation where the sub-circuit board 2 is easily deformed due to pressure when manually pressed.

[0029] As a further implementation of the above technical solution: the number of pressing plate 3 and the number of insert rods 5 and cutting plates 7 at its bottom are the same as the number of connecting blocks 4. A rubber layer is provided on the top of the pressing plate 3 to facilitate the operator to apply pressure to the pressing plate 3 when manually separating the mother circuit board 1 and the daughter circuit board 2.

[0030] Working principle:

[0031] When using this invention, during the separation of the main circuit board 1, the sub-circuit board 2 and the connecting block 4 are simultaneously cut by a machine tool. Insertion holes 8 are provided on both the left and right sides of the sub-circuit board 2. The inner wall of the insertion hole 8 is engraved with inwardly protruding locking blocks 9. After completion, the pressing plate 3, along with the insertion rod 5 and the cutting plate 7, are inserted into the insertion hole 8 from top to bottom. At this time, the insertion rod 5 enters the insertion hole 8, and after the locking block 9 is squeezed and deformed, the locking block 9 enters the locking grooves 6 on the left and right sides of the insertion rod 5, fixing the insertion rod 5. Simultaneously, the bottom of the cutting plate 7 also contacts the top of the connecting block 4. Installation is complete. When it is necessary to separate the main circuit board 1 from the sub-circuit board 2, the operator simultaneously squeezes the pressing plate 3 with both thumbs. The pressing plate 3 is under force, synchronously driving the insertion rod 5 and the cutting plate 7 downwards. The locking groove 6 on the outer side of the insertion rod 5 disengages from the locking block 9, and the cutting plate 7 also squeezes and breaks the connecting block 4, causing the sub-circuit board 2 to separate from the main circuit board 1. The operation is quick while avoiding direct pressure on the sub-circuit board 2.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
