Description

Technical Field

[0001] This utility model relates to the field of flexible printed circuit board (FPC) technology, and in particular to an FPC flexible printed circuit board with positioning function. Background Technology

[0002] Flexible printed circuit (FPC) cables, also known as FPC ribbon cables, are widely used in electronic devices where space is limited and dynamic bending or high-density wiring is required, due to their excellent characteristics such as thinness, flexibility, and foldability. Examples include laptops, mobile phones, display modules, printers, and various precision instruments. FPC cables typically connect electrically to the motherboard or adapter board on a device's functional module via connectors at both ends, thereby enabling signal or power transmission.

[0003] In existing technologies, the connection between the FPC flexible printed circuit board and the adapter board mainly relies on the mating and unmating of the connector itself. This connection method has obvious shortcomings: First, when the equipment is subjected to vibration, impact, or frequent mating operations, the connector itself is prone to loosening or even detachment due to friction or snap-fit ​​structure, resulting in signal transmission interruption or poor contact. Second, the relative position between the connector and the adapter board lacks an effective and adjustable locking mechanism. When subjected to external pulling force or equipment assembly stress, the connection point is prone to slight displacement, which also affects the reliability of the electrical connection. Furthermore, for applications requiring precise installation and positioning, the existing connection method cannot provide a stable and repeatable positioning reference, increasing assembly difficulty and maintenance risks. Utility Model Content

[0004] This invention addresses the problems in existing technologies where the connection between FPC ribbon cable flexible boards and adapter boards mainly relies on the insertion and removal of the connector itself, which leads to issues such as easy loosening and detachment, lack of effective locking, high risk of slight displacement, and difficulty in positioning. It provides an FPC ribbon cable flexible board with positioning function.

[0005] The technical solution adopted by this utility model is as follows: an FPC ribbon cable flexible board with positioning function, including an FPC ribbon cable body, both ends of the FPC ribbon cable body are connected to adapter plates through connectors, a positioning plate is fixedly connected to one side of the connector and sleeved on the outside of the adapter plate, guide posts are provided on the top and bottom walls of the positioning plate, a limit block is fixedly connected to the end of the guide post near the adapter plate, the limit block is connected to the positioning plate through a spring, screws are threaded to both sides of the positioning plate, a positioning plate is rotatably connected to the end of the screw near the adapter plate, and a knob is fixedly connected to the end of the screw away from the positioning plate.

[0006] As a further improvement of this utility model, the upper and lower surfaces of the FPC cable body are both wavy structures.

[0007] As a further improvement of this utility model, the outer surface of the limiting pressure block near the adapter plate is an inclined surface.

[0008] As a further improvement of this utility model, the spring is sleeved on the outside of the guide post.

[0009] As a further improvement of this utility model, the screw is rotatably connected to the positioning pressure plate through a bearing.

[0010] As a further improvement of this utility model, the positioning pressure plate is provided with granular anti-slip texture on the side near the adapter plate.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the positioning plate set on one side of the connector and sleeved on the outside of the adapter plate, combined with the limiting pressure block with spring pre-compression above and below it and the positioning pressure plate driven by the side screw, forms a double locking structure. When connected through the adapter plate, it achieves all-round, stable and adjustable clamping and fixing, effectively solving the problems of easy loosening, displacement and inaccurate positioning caused by connector plugging alone in the prior art. It significantly improves the mechanical stability and anti-interference ability of the connection point between the FPC ribbon cable and the adapter plate, and ensures the long-term reliability of signal transmission.

[0016] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0017] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-3 The FPC ribbon cable with positioning function shown includes an FPC ribbon cable body 1. Both ends of the FPC ribbon cable body 1 are connected to adapter plates 3 via connectors 2. A positioning plate 4 is fixedly connected to one side of the connector 2 and sleeved on the outside of the adapter plate 3. Guide posts 5 are provided on the top and bottom walls of the positioning plate 4. A limit block 6 is fixedly connected to the end of the guide post 5 near the adapter plate 3. The limit block 6 is connected to the positioning plate 4 via a spring 7. Screws 8 are threadedly connected to both sides of the positioning plate 4. A positioning plate 9 is rotatably connected to the end of the screw 8 near the adapter plate 3. A knob 10 is fixedly connected to the end of the screw 8 away from the positioning plate 9.

[0020] like Figure 1-3 As shown, the upper and lower surfaces of the FPC cable body 1 in this utility model are both wavy structures, which can increase the flexibility and bendability of the FPC cable body 1, enabling it to better adapt to various complex spatial layouts and dynamic bending requirements in practical applications.

[0021] like Figure 3 As shown, the outer surface of the limiting pressure block 6 near the adapter plate 3 in this utility model is an inclined surface. When connected through the adapter plate 3, the inclined surface can play a guiding role, making it easy for the adapter plate 3 to be smoothly inserted into the positioning plate 4.

[0022] like Figure 3 As shown, in this utility model, the spring 7 is sleeved on the outside of the guide post 5, which can ensure that the spring 7 will not deviate or twist during the extension and retraction process, and ensure that the pre-pressure of the spring 7 on the limiting block 6 is stable and reliable.

[0023] like Figure 3 As shown, in this utility model, the screw 8 is rotatably connected to the positioning plate 9 through the bearing 11, so that when the screw 8 rotates, the positioning plate 9 can move smoothly along the axial direction of the screw 8, avoiding the problem of inaccurate positioning caused by the positioning plate 9 rotating with the screw 8.

[0024] like Figure 3As shown, the positioning plate 9 in this utility model has granular anti-slip texture on the side near the adapter plate 3, which can increase the friction between the positioning plate 9 and the adapter plate 3, further improve the clamping stability of the adapter plate 3, and prevent sliding or displacement during connection through the adapter plate 3.

[0025] Working Principle: In practical implementation, when connecting the FPC cable body 1 to the equipment end via the adapter plates 3 at both ends, the equipment end connector is inserted between the positioning plate 4 and the adapter plate 3. During the insertion of the equipment end connector, the inclined surface of the limiting block 6 near the adapter plate 3 acts as a guide, allowing the adapter plate 3 to be inserted smoothly. The spring 7 is sleeved on the outside of the guide post 5. When the equipment end connector is inserted, the spring 7 is compressed, and the limiting block 6, under the preload of the spring 7, presses tightly against the upper surface of the equipment end connector, thus initially fixing and limiting the adapter plate 3.

[0026] Next, the operator rotates knob 10 to rotate screw 8. Since screw 8 is rotatably connected to positioning plate 9 via bearing 11, positioning plate 9 moves smoothly along the axial direction of screw 8 as screw 8 rotates. Positioning plate 9 moves closer to adapter plate 3 until its side with granular anti-slip texture presses firmly against the side wall of the equipment end connector. As screw 8 rotates further, positioning plate 9 applies greater pressure to the equipment end connector, forming a double locking structure together with limiting block 6, achieving omnidirectional, stable, and adjustable clamping and fixing of adapter plate 3.

[0027] During equipment use, even when subjected to vibration, impact, frequent plugging and unplugging operations, external pulling force, or equipment assembly stress, the stable structure formed by the positioning plate 4, the limiting pressure block 6, and the positioning pressure plate 9 can effectively prevent the equipment end connector from loosening or disengaging, as well as the connection point from undergoing slight displacement. This ensures the reliability of the electrical connection between the FPC ribbon cable and the equipment end, and guarantees the long-term stability of signal transmission.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
