Description

Technical Field

[0001] This utility model relates to a connector for a PCB board, and more particularly to a connector for a PCB board that is applied in the field of PCB board connector technology. Background Technology

[0002] In the design and manufacturing of electronic devices, the connection between PCBs (printed circuit boards) is a key link in realizing circuit functions. As electronic devices develop towards miniaturization, multi-functionality, and structural complexity, the performance requirements for PCB connectors are becoming increasingly stringent. Currently, board-to-board connectors are widely used in various electronic products, such as consumer electronics, industrial control equipment, and communication equipment. Their function is to establish a mechanical connection and electrical conduction between two PCBs, ensuring the stability of signal transmission and power supply. Traditional connectors usually consist of a female head, a male head, and conductive components. The female head and male head are fixed on different PCBs, and circuit connection is achieved through conductive contact.

[0003] However, in practical applications, the internal spatial layout of electronic devices is complex and varied. The PCBs of different functional modules often need to have their relative angles adjusted according to installation requirements and signal transmission optimization. However, traditional connectors are mostly fixed structures, and the angle is fixed after the two PCBs are connected. They cannot flexibly adapt to diverse spatial and circuit layout requirements. If the PCB angle needs to be changed, it is often necessary to replace it with a special connector designed with a specific angle. This not only increases the cost and cycle of equipment design and manufacturing, but also causes great inconvenience to engineers in troubleshooting and optimizing circuit layout during later maintenance and functional debugging due to the limitation of angle adjustment. It is difficult to meet the requirements of efficient and flexible design and use of modern electronic devices. Therefore, this utility model is proposed. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to solve the problem that the included angle between two PCB boards is not easy to adjust flexibly.

[0005] To address the aforementioned problems, this utility model provides a connector for a PCB board, comprising: a female connector, fixedly mounted on a first PCB board, the female connector having multiple grooves equidistantly spaced on it; a first conductive piece, fixedly connected within the grooves; a male connector, fixedly mounted on a second PCB board; a second conductive piece, fixedly connected to the male connector, the second conductive piece being symmetrically distributed on both sides of the first conductive piece; and conductive posts, inserted into the multiple grooves and rotatably connected to the female connector. The first conductive piece, the second conductive piece, and the female connector all have through holes for mating with the conductive posts. The female connector has multiple threaded holes equidistantly spaced around its circumference at one end near the conductive posts. An adjusting plate is fixedly connected to one end of the conductive posts near the threaded holes, and an adjusting bolt threaded into the threaded holes is inserted into the adjusting plate.

[0006] In the connectors of the aforementioned PCB board, the rotating connection design of the conductive post and the female connector, combined with the lockable adjustment structure, allows for flexible adjustment of the angle between the two PCB boards within a certain range without replacing the connector. This greatly expands the application scenarios, significantly improves adaptability, and can easily meet the diverse requirements of different equipment internal spaces and circuit layouts for the connection angle of the PCB board.

[0007] As a further improvement to this application, the adjustment plate is a transparent plate.

[0008] As a further improvement of this application, the end of the female connector away from the adjustment plate is rotatably connected to a threaded sleeve, and the end of the conductive post away from the adjustment plate is threadedly connected inside the threaded sleeve.

[0009] As a further improvement of this application, an insulating threaded post is fixedly connected to the end of the conductive post away from the adjustment plate, and the insulating threaded post is threadedly connected to the threaded sleeve.

[0010] As a further improvement of this application, a first limiting block for limiting the second conductive sheet is fixedly connected in the groove, and a second limiting block for limiting the first conductive sheet is fixedly connected on the male connector.

[0011] As a further improvement to this application, both the first limiting block and the second limiting block are made of insulating silicone rubber.

[0012] In summary, compared with existing technologies, the connector of this PCB board, through the rotating connection design of conductive posts and female connectors, coupled with a lockable adjustment structure, allows for flexible adjustment of the angle between the two PCB boards within a certain range without replacing the connectors. This greatly expands the application scenarios, significantly improves adaptability, and can easily meet the diverse requirements of different equipment internal spaces and circuit layouts for the connection angle of the PCB board.

[0013] After the angle is adjusted and fixed, the symmetrical structure of the first and second conductive plates, along with the conductive post, increases the electrical connection contact area and stability, reducing the risk of poor contact. At the same time, the locking of the adjusting bolt and threaded hole ensures the stable position of the conductive post, preventing the PCB board angle from changing or the connection from loosening due to vibration or external force during equipment operation. This ensures the continuity and stability of signal or power transmission and reduces the probability of circuit failure caused by connection problems.

[0014] During installation, no complicated tools or special processes are required. Connector assembly, angle adjustment and fixation can be completed by following the procedure, which lowers the operation threshold. If the PCB board angle needs to be adjusted for later maintenance, the adjusting bolts can be loosened, the angle readjusted and then tightened again. Compared with the cumbersome replacement or adjustment of traditional fixed connectors, maintenance efficiency and flexibility are greatly improved. Attached Figure Description

[0022] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0023] Implementation method:

[0024] Figures 1-5 The diagram shows a connector for a PCB board, comprising: a female connector 3, fixedly mounted on a first PCB board 1, the female connector 3 having multiple grooves equidistantly spaced on it; a first conductive sheet 301, fixedly connected within the grooves; a male connector 4, fixedly mounted on a second PCB board 2; a second conductive sheet 401, fixedly connected to the male connector 4, the second conductive sheet 401 being symmetrically distributed on both sides of the first conductive sheet 301; and conductive posts 5, inserted into the multiple grooves and rotatably connected to the female connector 3. The first conductive sheet 301, the second conductive sheet 401, and the female connector 3 all have through holes for mating with the conductive posts 5. The female connector 3 has multiple threaded holes 303 equidistantly spaced around its circumference near one end of the conductive post 5. An adjusting plate 501 is fixedly connected to one end of the conductive post 5 near the threaded holes 303, and an adjusting bolt 502, threadedly connected to the threaded holes 303, is inserted into the adjusting plate 501.

[0025] When connecting two PCB boards using connectors, firstly, confirm that the corresponding circuit design and fabrication of the first PCB board 1 and the second PCB board 2 have been completed. Then, securely install the female connector 3 on the first PCB board 1 using a suitable method (such as soldering, snap-fit, etc., depending on the actual fixing structure). Install the male connector 4 on the second PCB board 2 in the same way, ensuring that all components are not loose or damaged, and that key parts such as conductive sheets are clean and free of foreign objects.

[0026] Next, the conductive post 5 is inserted into the multiple equally spaced grooves on the female connector 3. Utilizing the rotational connection characteristics between the female connector 3 and the conductive post 5, the second conductive piece 401 on the male connector 4 can correspond to the first conductive piece 301 in the groove of the female connector 3. Since the second conductive piece 401 is symmetrically distributed on both sides of the first conductive piece 301, the pre-contact guidance for electrical connection can be initially achieved.

[0027] According to actual installation or circuit requirements, the conductive post 5 can be manually rotated to drive the male connector 4 and the second PCB board 2 to rotate relative to the female connector 3 and the first PCB board 1. This allows for flexible adjustment of the angle between the two PCB boards. During the rotation, the rotational cooperation structure between the female connector 3 and the conductive post 5 can easily achieve switching between multiple angles (such as adjustment within the range of 0°-180°, depending on the structural limits) to meet the requirements of different installation spaces and circuit layouts for the PCB board angle.

[0028] After the angle between the two PCB boards is adjusted to the target angle, the angle is fixed: Locate the threaded holes 303 equidistantly spaced on the circumference of the female connector 3 near the conductive post 5, and the adjustment plate 501 fixedly connected to the corresponding end of the conductive post 5. Insert the adjustment bolt 502 into the adjustment plate 501, and then screw it into the corresponding threaded hole 303 and tighten it. Through the threaded connection between the adjustment bolt 502 and the threaded hole 303, the rotation position of the conductive post 5 is locked, thereby fixing the angle between the two PCB boards and stabilizing the connection. At this time, the first conductive piece 301, the second conductive piece 401 and the conductive post 5 cooperate to ensure the continuous conduction of electrical connection through the through hole, so as to realize the stable transmission of signal or power between the two PCB boards.

[0029] Existing traditional fixed connectors are limited by their structure, with the angle between the two PCB boards fixed. This limits their applicability to a single scenario. When faced with complex internal spaces of equipment (such as narrow cavities or situations requiring special angles to avoid other components) or diverse circuit connection needs (signal transmission between different modules requires specific angle layout optimization), they cannot be flexibly adjusted. Often, it is necessary to replace them with dedicated connectors, increasing costs and design complexity. However, this connector, through the rotating connection design of the conductive post 5 and the female connector 3, combined with a lockable adjustment structure, allows for flexible adjustment of the angle between the two PCB boards within a certain range without replacing the connector. This greatly expands the application scenarios, significantly improves adaptability, and can easily meet the diverse requirements of different internal spaces and circuit layouts of equipment for the connection angle of the PCB boards.

[0030] After the angle is adjusted and fixed, the symmetrical structure of the first conductive plate 301 and the second conductive plate 401, which are matched with the conductive post 5, increases the electrical connection contact area and stability, reduces the risk of poor contact, and at the same time, the locking of the adjusting bolt 502 and the threaded hole 303 makes the position of the conductive post 5 stable, avoiding the PCB board angle change and connection loosening caused by vibration or external force during equipment operation, ensuring the continuity and stability of signal or power transmission, and reducing the probability of circuit failure caused by connection problems.

[0031] During installation, no complicated tools or special processes are required. Connector assembly, angle adjustment and fixation can be completed by following the procedure, which reduces the operation threshold. If the PCB board angle needs to be adjusted for maintenance in the later stage (such as internal layout optimization of equipment or troubleshooting that requires changing the connection angle for testing), the adjustment bolt 502 can be loosened easily, the angle can be readjusted and then tightened to fix it. Compared with the cumbersome replacement or adjustment of traditional fixed connectors, maintenance efficiency and flexibility are greatly improved.

[0032] Figures 1-5 As shown, the adjustment plate 501 is a transparent plate.

[0033] By making the adjustment plate 501 transparent, its light-transmitting properties allow operators to clearly observe the position of the threaded hole 303 on the female connector 3 when installing the adjustment bolt 502. This eliminates the need for repeated alignment and adjustments, enabling the adjustment bolt 502 to be quickly and accurately inserted into the corresponding threaded hole 303 and tightened. This significantly improves the efficiency and accuracy of angle fixing operations and reduces the probability of installation errors caused by visual obstruction. The advantages are even more pronounced in confined spaces or batch installation scenarios, making the entire connector angle adjustment and fixing process smoother and more convenient.

[0034] Figures 1-5As shown, the end of the female connector 3 furthest from the adjustment plate 501 is rotatably connected to a threaded sleeve 504, and the end of the conductive post 5 furthest from the adjustment plate 501 is threadedly connected inside the threaded sleeve 504. When it is necessary to disassemble, maintain, or replace parts of the connector, no complicated operation is required. Simply rotate the threaded sleeve 504 and use the engagement and disengagement characteristics of the thread to quickly disconnect or reassemble the conductive post 5 and the female connector 3. This simplifies the disassembly and assembly process, reduces the requirements for tools and operating skills, and makes it more convenient and efficient to separate two PCB boards during routine maintenance or to replace internal parts of the connector. This improves the overall maintainability and flexibility of the connector.

[0035] An insulating threaded post 503 is fixedly connected to the end of the conductive post 5 away from the adjustment plate 501. The insulating threaded post 503 is threaded into the threaded sleeve 504. The insulating threaded post 503 is fixedly connected to the end of the conductive post 5 away from the adjustment plate 501 and threaded into the threaded sleeve 504. The insulating material can block the electrical conduction between the conductive post 5 and the threaded sleeve 504, preventing the current from being accidentally conducted to the shell of the female connector 3 or other non-conductive parts through the threaded sleeve 504. This effectively prevents the risk of short circuit and ensures the safety of the circuit connection. At the same time, the insulating threaded post 503 retains the advantage of easy disassembly and assembly of the threaded connection, and eliminates the leakage hazard that may be caused by direct contact between metal parts through material isolation. This allows the mechanical fixation and electrical insulation performance of the conductive post 5 to be synergistically optimized, improving the overall reliability of the connector.

[0036] Figures 1-5 As shown, a first limiting block 302 for limiting the second conductive sheet 401 is fixedly connected in the groove, and a second limiting block 402 for limiting the first conductive sheet 301 is fixedly connected on the male connector 4.

[0037] Both the first limiting block 302 and the second limiting block 402 are made of insulating silicone rubber.

[0038] A first limiting block 302 is set in the groove to limit the second conductive piece 401, and a second limiting block 402 is set on the male connector 4 to limit the first conductive piece 301. Both are made of insulating silicone rubber. From the perspective of structural stability, the limiting block can accurately constrain the position of the conductive piece, preventing the conductive piece from shifting or misaligning due to vibration or external force when the male and female connectors are inserted or the angle is adjusted. This ensures that the first conductive piece 301 and the second conductive piece 401 always maintain stable contact, reducing the risk of poor contact. In terms of insulation performance, the insulating silicone rubber material can block accidental conduction between the conductive piece and the connector shell or other metal parts, preventing short circuit faults. At the same time, silicone rubber has good elasticity and flexibility, which can buffer the impact force during insertion during the limiting process, avoiding wear or damage to the conductive piece caused by rigid contact, extending the service life of the connector, and providing double protection for the stability and safety of the electrical connection.

[0040] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
