Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with a guiding and positioning plug-in structure. Background Technology

[0002] A circuit board, also known as a printed circuit board, is one of the most important basic components in electronic devices. It is mainly used to support electronic components and provide electrical connections.

[0003] In the current circuit board technology field, the insertion and connection of circuit boards to each other or to electronic components is a common assembly method. Traditional circuit board insertion structures usually rely on manual alignment of pins and slots. Due to the lack of a precise guiding and positioning mechanism, alignment deviations are prone to occur, leading to problems such as low insertion efficiency or poor contact. In addition, existing insertion structures mostly use a single mechanical clip or simple spring locking. Under scenarios such as vibration and frequent insertion and removal, the pins are prone to loosening after mating with the slot, affecting the stability and reliability of the connection. Therefore, there is an urgent need for a circuit board with a guided and positioned insertion structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board with a guided positioning and plug-in structure. Its advantages are: the guiding, positioning, and damping functions are integrated into one unit via a guide seat, allowing plug-in and locking to be completed without additional tools, resulting in a simple and efficient operation process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit board with a guided positioning and plug-in structure includes a board body and further includes:

[0007] A guiding component that facilitates stable docking of pins with the connector slots;

[0008] To prevent the positioning component from becoming loose after the pins mate with the slots, the positioning component is located inside the guide component;

[0009] A connection board used to fix the pins.

[0010] The above technical solution integrates guiding, positioning, and damping functions into one unit through the guide seat, allowing for insertion and locking without additional tools, making the operation process simple and efficient.

[0011] The present invention is further configured such that the guiding component includes a guiding seat fixedly connected to the top outer wall of the plate, the guiding seat having a guiding groove inside, and a guiding block fixedly connected to the bottom outer wall of the connecting plate, the guiding block cooperating with the guiding groove.

[0012] The above technical solutions can provide a precise guiding path for the connector board, enabling the pins to be accurately inserted into the socket along the predetermined direction, effectively avoiding alignment deviations caused by manual operation.

[0013] The present invention is further configured such that a sloping groove is provided on the top outer wall of the guide seat, and the sloping groove is connected to the guide groove.

[0014] The above technical solutions simplify the initial alignment steps of the insertion process, improve insertion efficiency, and are especially suitable for batch assembly operations.

[0015] The present invention is further configured such that the positioning component includes a cavity opened inside the guide seat, and a sliding plate is slidably connected to both inner walls of the cavity. A curved column is fixedly connected to the middle of the sliding plate, and a locking head is fixedly connected to one end of the curved column. A locking groove that cooperates with the locking head is opened on one side of the guide block.

[0016] Through the above technical solution: after the guide block is fully inserted, the spring pushes the slide plate to make the locking head lock into the locking groove of the guide block to form a mechanical lock, thereby preventing the pin from loosening after it is connected to the insertion groove and ensuring the stability of the connection.

[0017] The present invention is further configured such that a spring is fixedly connected to one side of the inner wall of the cavity, and the other end of the spring is fixedly connected to one side of the outer wall of the slide plate.

[0018] Through the above technical solution: when the guide block reaches the predetermined position, the spring releases its elastic potential energy to push the slide plate, so that the locking head is precisely engaged in the locking groove, thereby achieving a firm lock on the guide block.

[0019] The present invention is further configured such that a connecting block is fixedly connected to the end of the bent column away from the locking head.

[0020] Through the above technical solutions, the connecting block plays an auxiliary role in connection and operation. On the one hand, it can provide workers with a convenient part to apply force during installation or maintenance, making it easier to operate the bent column.

[0021] The present invention is further configured such that an extension plate is fixedly connected to one side of the outer wall of the guide seat, and a damping component is provided inside the extension plate.

[0022] Through the above technical solutions, the damping component can adjust the insertion speed and force during the docking process between the pin and the slot, avoiding damage to the circuit board and pins due to excessive insertion speed or force. At the same time, it can also play a buffering role during unlocking, improving the safety and stability of the operation.

[0023] The present invention is further configured such that the damping component includes a clamping groove formed inside the extension plate, and a rubber sleeve is fixedly connected to the outer circumference of the curved column. The cross-sections of the rubber sleeve and the clamping groove are both isosceles trapezoids, and the inner diameter of the clamping groove gradually decreases along the direction close to the connecting block.

[0024] Through the above technical solution: as the inner diameter of the clamping groove gradually decreases towards the connecting block, the rubber sleeve will be squeezed by the clamping groove to generate a damping force. This damping force makes the insertion process more stable and controllable, preventing the impact caused by the rapid insertion of the guide block. When unlocking, the damping force generated by the rubber sleeve can buffer the spring's rebound, avoiding misoperation caused by the rapid rebound of the spring, and ensuring the reliability of the connection and the safety of the operation.

[0025] The present invention is further configured such that a through groove is provided inside the guide seat, and the bent column passes through the inside of the through groove, and the through groove is connected to the cavity and the clamping groove.

[0026] Through the above technical solution, the through groove provides a channel for the sliding of the bent column, allowing it to move freely between the cavity and the clamping groove.

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. In this application, a stepped guide structure is formed by the ramp groove and guide groove in the guide component. The guide block at the bottom of the connecting board can slide quickly into the guide groove along the ramp groove to achieve precise alignment of the pin and the insertion slot. This design reduces manual alignment error and makes the insertion process more efficient and smooth, especially suitable for the rapid assembly of high-density circuit boards.

[0029] 2. In this application, the positioning component uses a spring to drive the locking head to engage with the locking groove of the guide block, forming a mechanical lock. This effectively prevents the pin from loosening after it is connected to the insertion groove. At the same time, the isosceles trapezoidal rubber sleeve of the damping component is squeezed and cooperates with the clamping groove to generate a stable damping force. This not only makes the insertion process smooth and controllable, but also buffers the spring rebound when unlocking, avoiding connection failure caused by misoperation, and further improving the reliability and durability of the connection.

[0030] 3. This application integrates guiding, positioning, and damping functions into one unit through a guide seat, which can complete the insertion and locking without additional tools. The operation process is simple and efficient. At the same time, the standardized guide block and guide groove design can be adapted to different specifications of pins and insertion slots. By adjusting the parameters of the rubber sleeve and spring, it can flexibly adapt to different insertion force requirements, improving the versatility and scenario adaptability of the circuit board. It is especially suitable for electronic devices with high requirements for space layout and compatibility. Attached Figure Description

[0036] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0037] Reference Figures 1-4 This application provides a circuit board with a guide positioning plug-in structure, including a board body 1, a guide component 3 to facilitate stable docking of pin 6 with plug-in slot 2, a positioning component 5 to prevent loosening after the pin 6 docks with plug-in slot 2, the positioning component 5 being disposed inside the guide component 3, and a connecting plate 4 for fixing the pin 6.

[0038] In order to improve the accuracy and stability of the connection, refer to Figures 1-3 The guiding component 3 includes a guide seat 3002 fixedly connected to the top outer wall of the plate 1. The guide seat 3002 has a guide groove 3004 inside. A guide block 3001 is fixedly connected to the bottom outer wall of the connecting plate 4. The guide block 3001 cooperates with the guide groove 3004. The cooperation between the guide block 3001 and the guide groove 3004 can provide a precise guiding path for the connecting plate 4 during the docking of the pin 6 and the insertion slot 2, so that the pin 6 can be accurately inserted into the insertion slot 2 along the predetermined direction, effectively avoiding the alignment deviation caused by manual operation.

[0039] Reference Figures 2-3To improve insertion efficiency, a ramp groove 3003 is provided on the top outer wall of the guide seat 3002. The ramp groove 3003 is connected to the guide groove 3004, and the ramp groove 3003 and the guide groove 3004 are connected to form a stepped guide structure. When performing insertion operation, the operator only needs to align the guide block 3001 at the bottom of the connecting plate 4 with the ramp groove 3003. The guide block 3001 can then quickly slide into the guide groove 3004 under its own weight and the guidance of the ramp. This simplifies the initial alignment steps of insertion, improves insertion efficiency, and is especially suitable for batch assembly operations.

[0040] Reference Figures 3-4 In some embodiments, to ensure the stability of the connection, the positioning component 5 includes a cavity 5007 formed inside the guide seat 3002. Slide plates 5010 are slidably connected to both inner walls of the cavity 5007. A bent post 5002 is fixedly connected to the middle of the slide plate 5010. A locking head 5009 is fixedly connected to one end of the bent post 5002. A locking groove 5008 that mates with the locking head 5009 is formed on one side of the guide block 3001. When the guide block 3001... During the insertion of the guide block 3004, the guide block 3001 will squeeze the locking head 5009, causing the bent post 5002 and the slide plate 5010 to slide in the cavity 5007. When the guide block 3001 is fully inserted, the spring 5011 (which will be mentioned later) pushes the slide plate 5010 to make the locking head 5009 lock into the locking groove 5008 of the guide block 3001 to form a mechanical lock, thereby preventing the pin 6 from loosening after docking with the insertion groove 2 and ensuring the stability of the connection.

[0041] Please continue to refer to Figure 3 and Figure 4 In order to ensure the reliability of the connection between pin 6 and the insertion slot 2, a spring 5011 is fixedly connected to one inner wall of cavity 5007. The other end of spring 5011 is fixedly connected to one outer wall of slide plate 5010. Spring 5011 serves as the power source of positioning component 5. When guide block 3001 is inserted, it is compressed and stores elastic potential energy. When guide block 3001 reaches the predetermined position, spring 5011 releases elastic potential energy to push slide plate 5010, so that locking head 5009 is accurately engaged in locking slot 5008, thereby achieving a firm lock on guide block 3001.

[0042] Please continue to refer to Figure 3 and Figure 4 In order to facilitate the subsequent stable unlocking of the positioning component 5 by the staff, the end of the bent column 5002 away from the locking head 5009 is fixedly connected to the connecting block 5001. The connecting block 5001 plays the role of auxiliary connection and operation. On the one hand, it can provide the staff with a part that is easy to apply force during installation or maintenance, and facilitate the operation of the bent column 5002.

[0043] Please continue to refer to Figure 3 and Figure 4 To prevent damage to pin 6 during insertion, an extension plate 5003 is fixedly connected to one outer wall of the guide seat 3002. The extension plate 5003 has a damping component inside, which provides a mounting base for the damping component, enabling the damping component to work in conjunction with the positioning component 5. During the docking of pin 6 with the insertion slot 2, the damping component can adjust the insertion speed and force to avoid damage to the circuit board and pin 6 due to excessive insertion speed or force. At the same time, it can also play a buffering role during unlocking, improving the safety and stability of the operation.

[0044] like Figure 3 and Figure 4 As shown, to prevent impact caused by the rapid insertion of the guide block 3001 and to facilitate stable unlocking work for the operator, the damping assembly includes a clamping groove 5004 formed inside the extension plate 5003. A rubber sleeve 5005 is fixedly connected to the outer circumferential wall of the bent column 5002. The cross-sections of both the rubber sleeve 5005 and the clamping groove 5004 are isosceles trapezoids. The inner diameter of the clamping groove 5004 gradually decreases along the direction close to the connecting block 5001. During the process of the guide block 3001 being inserted into the guide groove 3004, the bent column 5002... The movable rubber sleeve 5005 slides within the clamping groove 5004. As the inner diameter of the clamping groove 5004 gradually decreases towards the connecting block 5001, the rubber sleeve 5005 is compressed by the clamping groove 5004, generating a damping force. This damping force makes the insertion process more stable and controllable, preventing the impact caused by the rapid insertion of the guide block 3001. When unlocking, the damping force generated by the rubber sleeve 5005 can buffer the rebound of the spring 5011, avoiding misoperation caused by the rapid rebound of the spring 5011, and ensuring the reliability of the connection and the safety of the operation.

[0045] To ensure stable mating and reliable locking of pin 6 with slot 2, refer to... Figure 3 and Figure 4 The guide seat 3002 has a through groove 5006 inside, and the bent column 5002 passes through the inside of the through groove 5006. The through groove 5006 is connected to the cavity 5007 and the clamping groove 5004. The through groove 5006 provides a channel for the sliding of the bent column 5002, allowing it to move freely between the cavity 5007 and the clamping groove 5004, ensuring the linkage between the positioning component 5 and the damping component. Through the through groove 5006, the bent column 5002 can transmit the force when the guide block 3001 is inserted to the positioning component 5 and the damping component, realizing the coordinated work between the components.

[0046] The working principle of this application is as follows: When it is necessary to connect two circuit boards or one circuit board to other components (it should be noted that the circuit board or electrical component is fixedly connected to the connecting plate 4), firstly, the guide block 3001 on the connecting plate 4 is aligned with the ramp groove 3003 at the top of the guide seat 3002 and inserted. At this time, under the guidance of the ramp groove 3003, the guide block 3001 slides into the guide groove 3004, so that the pin 6 is initially aligned with the insertion groove 2 and inserted. During the insertion process, the guide block 3001 will squeeze the locking head 5009 in the positioning assembly 5, thereby driving the bent column 5002 and the sliding plate 501. The spring 5011 slides and compresses within the cavity 5007, while the rubber sleeve 5005 on the bent column 5002 is squeezed within the clamping groove 5004 of the extension plate 5003 (the inner diameter of the clamping groove 5004 gradually decreases towards the connecting block 5001, and the cross-section of the rubber sleeve 5005 is an isosceles trapezoid), generating a damping force that makes the insertion process smooth. Furthermore, when unlocking the positioning component 5, the damping force generated by the rubber sleeve 5005 can prevent the spring 5011 from rebounding quickly, providing time for the operator to pull the guide block 3001 out of the guide groove 3004, thus facilitating operation.

[0047] After the guide block 3001 is fully inserted, the locking head 5009 is engaged in the locking groove 5008 of the guide block 3001 by the elastic force of the spring 5011 to complete the positioning, so as to prevent the pin 6 from loosening after docking with the insertion groove 2. At the same time, the guide component 3 and the positioning component 5 cooperate to achieve stable docking and positioning of the pin 6 and the insertion groove 2.

[0048] 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.
