Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC board technology, specifically to an anti-detachment FPC socket. Background Technology
[0002] FPC, or flexible printed circuit board, is a type of printed circuit board made with polyimide or polyester film as the substrate, offering high reliability and excellent flexibility. FPCs are characterized by high wiring density, light weight, thinness, and good bendability, making them suitable for achieving complex electrofusion connections in confined spaces. FPCs are widely used in smartphones, laptops, digital cameras, medical devices, automotive electronics, and aerospace. The manufacturing process of FPCs is relatively complex, involving multiple steps such as material preparation, baking, dry film lamination, exposure, development, etching, film removal, pretreatment, cover film lamination, lamination, curing, surface treatment, electrical testing, assembly, text marking, shaping, and final inspection. Due to the special properties of FPCs, their production process must be carried out in a cleanroom environment to ensure product quality and performance.
[0003] When installing FPC connector plugs, clips are usually used for direct connection. However, after prolonged use, the clips may loosen, causing the FPC board to detach from the connector. This prevents the connected circuit board from being connected, resulting in equipment damage. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an anti-detachment FPC socket, including a connector. The connector has pins on its front side and an installation hole inside. The installation hole contains a locking sleeve and a limit locking hole. A sliding groove is provided on the front side of the connector. A connecting platform is engaged inside the installation hole. An installation box is fixedly connected to the rear end of the connecting platform. A ramp is fixedly connected to the surface of the installation box. A spring is fixedly connected to the inner wall of the connecting platform. A non-circular plate is fixedly connected to the top of the spring. A pressing block is fixedly connected to the top of the non-circular plate. A limit sleeve is fitted onto the surface of the pressing block. A fixing post is fixedly connected to the top of the inner wall of the installation box. An arc-shaped platform is fixedly connected to the bottom of the installation hole. A locking post is fixedly connected to the bottom of the non-circular plate. A sliding strip is fixedly connected to the bottom of the installation box. An FPC board is disposed inside the connector.
[0005] The above technical solution involves inserting the main FPC board into the connector by setting up a shaped component. Then, a slider is placed inside the sliding groove and slid. Pressing the pressing block causes the shaped component's surface to contact the surface of the curved platform, at which point the locking pin is raised. The connecting platform is then fixedly inserted into the mounting hole until the mounting box connects with the surface of the connector. The pressing block is then released, and under the action of the spring, it engages the locking pin inside the limiting hole. Once the locking pin is engaged, the bottom of the inclined platform connects to the top of the FPC board, forming a fixed connection. The locking pin also secures the connector to the connecting platform, preventing the FPC board from falling off.
[0006] As a further improvement to the above solution, two mounting holes are provided, and the two mounting holes are evenly distributed on the surface with respect to the center of the rear end surface of the connector.
[0007] The above technical solution uses two mounting holes, symmetrically and evenly distributed around the center of the rear surface of the connector. This symmetrical distribution helps maintain force balance during installation, making the FPC board more stable in the socket and reducing the risk of loosening or falling off due to uneven force. The two mounting holes can share the connection pressure of the FPC board, providing a more reliable connection compared to a single mounting hole, and improving the overall socket's ability to secure the FPC board.
[0008] As a further improvement to the above solution, two connecting platforms are provided, each of which is snapped into the interior of the mounting hole, and the inclined platform is provided on the inner surface of the two mounting boxes.
[0009] With the above technical solution, the inclined platform is set on the inner surface of the two mounting boxes. This layout helps to limit and support the FPC board from both sides when installing it. Together with the connecting platform and other components, it enhances the fixing effect of the FPC board and prevents the FPC board from falling off due to lateral displacement during use.
[0010] As a further improvement to the above solution, the pressing block penetrates the top of the connector, and the limiting sleeve is disposed on the top of the inner wall of the mounting box, with the limiting sleeve being concentric with the pressing block.
[0011] As a further improvement to the above solution, the irregularly shaped plate is fitted onto the surface of the fixed column.
[0012] Through the above technical solution, the movement of the irregularly shaped plate is guided and limited. When the pressing block is pressed, the irregularly shaped plate can move stably up and down along the fixed post, ensuring the accuracy of the spring's extension and contraction and the engagement or disengagement of the locking post with the limiting hole, thereby ensuring the fixation and release of the entire socket on the FPC board.
[0013] As a further improvement to the above solution, the locking pin is engaged inside the limiting hole, the slider is slidably connected inside the slide groove, and the bottom of the inclined platform is connected to the FPC plate.
[0014] Through the above technical solution, the bottom of the inclined platform is connected to the FPC board. This connection method allows the inclined platform to directly apply support and limiting force to the FPC board. Together with other components, it ensures the stable installation of the FPC board in the socket and prevents it from being detached from the socket due to external forces during use.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention uses a shaped component to insert the main FPC board into the connector. A slider is then placed inside the sliding groove and slid. Pressing the pressing block causes the shaped component's surface to contact the surface of the curved platform, raising the locking pin. The connecting platform is then fixedly inserted into the mounting hole until the mounting box connects to the surface of the connector. Releasing the pressing block, driven by a spring, causes the locking pin to engage with the limiting hole. Once engaged, the bottom of the inclined platform connects to the top of the FPC board, forming a fixed connection. The locking pin also secures the connector to the connecting platform, preventing the FPC board from detaching. Attached Figure Description

After the locking post 15 is locked inside the limiting locking hole 4, the connector 1 and the connecting platform 6 are fixed to prevent the FPC plate 17 from falling off.
[0026] There are two mounting holes 3, which are evenly distributed on the surface with the rear end surface of the connector 1 symmetrically centered.
[0027] There are two connecting platforms 6, which are respectively snapped into the inside of the mounting hole 3, and the inclined platform 8 is set on the inner surface of the two mounting boxes 7.
