Description
Technical Field
[0001] The utility model relates to the technical field of FPC, and more specifically, to an FPC structure for preventing tilting during insertion and extraction. Background Art
[0002] With the rapid development of technology, display screen technology has been increasingly widely used in various fields. From smartphones, tablets to TVs, in-vehicle displays, and various industrial control screens, display screens have become an essential component for human-computer interaction. In these display screen systems, flexible printed circuit boards (FPCs), as a key connecting component, play an irreplaceable role in signal transmission between the display screen and the main board due to their excellent flexibility, high integration, and low cost.
[0003] However, in the actual application process, the insertion and extraction operations of FPCs have become a potential hidden danger. Due to the complex and changeable operating environment, the uneven technical levels of operators, and the limitations in product design, FPCs often tilt during insertion and extraction. This tilting insertion and extraction not only cause physical damage to the FPC itself, such as bending, twisting, or even breaking, but more importantly, it directly affects the alignment accuracy between the FPC and the connector interface. Once the circuit is misconnected, a series of problems such as short circuit and signal interference may occur, resulting in abnormal display of the display screen at the least, and may even burn out the entire display screen module at the worst, bringing huge economic losses and inconvenience to users. In addition, the pins inside the connector are also victims of tilting insertion and extraction. These pins are usually designed to be relatively thin and precise to ensure good electrical connection with the contacts on the FPC. However, when the FPC is inserted at an inclined angle, the pins will bear additional lateral forces, which may cause the pins to bend, deform, or even break, thus destroying the integrity and stability of the electrical connection. Once the pins are damaged, the entire connector needs to be replaced or complex repair work needs to be carried out, which not only increases the maintenance cost but also prolongs the downtime of the equipment and reduces the production efficiency. Therefore, we have made improvements in this regard and proposed an FPC structure for preventing tilting during insertion and extraction. Summary of the Utility Model

[0034] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0035] Embodiment 1 of the FPC structure with anti-tilting plugging and unplugging of the present utility model
[0036] The FPC structure with anti-tilting plugging and unplugging of the present utility model includes: an FPC connector 2 and an FPC main body 3 connected to the FPC connector 2. An FPC reinforcing plate 4 is provided on the FPC main body 3. An extension plate 5 is provided on the side of the FPC reinforcing plate 4, and a limiting portion is provided on the extension plate 5. The limiting portion is used to achieve the limiting during the plugging and unplugging of the FPC reinforcing plate 4. In this application, a limiting portion is provided on the FPC reinforcing plate 4, and the limiting portion can achieve the limiting during the plugging and unplugging of the FPC reinforcing plate 4, so that the FPC reinforcing plate 4 can be in the vertical direction during the plugging and unplugging process, effectively preventing the risk of circuit misconnection and short circuit caused by tilting plugging and unplugging, reducing the mechanical impact and wear on the connector pins caused by tilting plugging and unplugging, prolonging the service life of the connector, reducing the maintenance cost, improving the overall reliability and stability of the product by reducing the failure rate caused by improper plugging and unplugging, and enhancing the market competitiveness.
[0037] Further, as Figure 2 and Figure 3As shown, the limiting part includes an extension plate 5. The extension plate 5 is arranged on the side of the FPC reinforcing plate 4. A limiting card slot 6 is arranged between the extension plate 5 and the FPC reinforcing plate 4. The inner wall of the limiting card slot 6 is slidably connected to the outer side surface of the FPC connector 2. Through the mutual cooperation of the outer side surface of the FPC connector 2 and the limiting card slot 6, the extension plate 5 can be limited, and further, the FPC reinforcing plate 4 and the FPC main body 3 can be limited, so that the FPC reinforcing plate 4 and the FPC main body 3 can maintain vertical insertion and extraction during the insertion and extraction process, so as to solve the problem that the FPC main body 3 tilts during the insertion and extraction process.
[0038] Further, as Figure 1 shown, an arc slope is arranged at the opening of the limiting card slot 6. The arrangement of the arc slope plays a guiding role and can facilitate the connection between the limiting card slot 6 and the outer side surface of the FPC connector 2 during insertion.
[0039] Further, as Figure 1 shown, the number of the extension plates 5 and the limiting card slots 6 is two. The two extension plates 5 are respectively arranged on both sides of the FPC reinforcing plate 4. The design of using two extension plates 5 can limit both sides of the FPC reinforcing plate 4, and further improve the stability of the insertion and extraction of the FPC reinforcing plate 4.
[0040] Embodiment Two of the FPC Structure with Anti-Tilting Insertion and Extraction of the Present Utility Model
[0041] Further, as for the FPC structure with anti-tilting insertion and extraction of the present utility model, as Figure 3 shown, the width of the extension plate 5 is the same as that of the FPC reinforcing plate 4. Such a design makes the FPC reinforcing plate 4 and the extension plate 5 show a high degree of integration and compactness both visually and physically. This compact structure helps to save space, makes the layout of the entire FPC component in the electronic device more reasonable, and is beneficial to the design goals of miniaturization and light weight.
[0042] Embodiment Three of the FPC Structure with Anti-Tilting Insertion and Extraction of the Present Utility Model
[0043] Further, as for the FPC structure with anti-tilting insertion and extraction of the present utility model, as Figure 4 shown, the width of the extension plate 5 is greater than that of the FPC reinforcing plate 4. Such a setting makes the limiting card slot 6 contact the FPC connector 2 first during the insertion process, and the limiting card slot 6 separates from the FPC connector 2 later during the unplugging process, thereby ensuring the limitation of the insertion and extraction process of the FPC reinforcing plate 4.
[0044] Embodiment Four of the FPC Structure with Anti-Tilting Insertion and Extraction of the Present Utility Model
[0045] For the FPC structure with anti-tilting plugging and unplugging of the present utility model, further, the FPC connector 2 is connected to the main circuit board 1, and limit members are provided between the main circuit board 1 and the two extension plates 5. The limit members can further limit the extension plates 5 during the plugging and unplugging process to further reduce the tilting of the FPC main body 3.
[0046] Further, the limit members are used for limiting the movement of the extension plates 5 to achieve anti-tilting of the FPC reinforcement plates 4.
[0047] Embodiment Five of the FPC Structure with Anti-tilting Plugging and Unplugging of the Present Utility Model
[0048] For the FPC structure with anti-tilting plugging and unplugging of the present utility model, further, as Figure 5 shown, the limit member includes a limit seat 7 fixedly installed on the main circuit board 1. A limit slot 701 is opened on one side of the limit seat 7 close to the FPC connector 2. The extension plate 5 is inserted into the inner wall of the limit slot 701. The insertion of the extension plate 5 into the limit slot 701 can limit the extension plate 5 to keep the extension plate 5 stable and reduce the tilting of the FPC main body 3;
[0049] During insertion, align the extension plate 5 with the limit slot 701 and insert it into the limit slot 701. At this time, the extension plate 5 is first inserted into the limit slot 701, and the FPC reinforcement plate 4 is not inserted into the FPC connector 2. Then continue to push the FPC reinforcement plate 4 so that the FPC reinforcement plate 4 drives the FPC main body 3 to be inserted into the FPC connector 2. When unplugging, directly pull the FPC reinforcement plate 4 so that the FPC reinforcement plate 4 drives the FPC main body 3 to be separated from the FPC connector 2, and continue to pull so that the extension plate 5 is separated from the limit slot 701.
[0050] Embodiment Six of the FPC Structure with Anti-tilting Plugging and Unplugging of the Present Utility Model
[0051] For the FPC structure with anti-tilting plugging and unplugging of the present utility model, further, as Figure 6 shown, the limit member includes a limit chute 8 opened on the extension plate 5. A limit plate 9 is slidably connected in the limit chute 8. One end of the limit plate 9 is fixedly connected to the main circuit board 1. The mutual cooperation of the limit chute 8 and the limit plate 9 can limit the extension plate 5 to keep the extension plate 5 stable during movement and reduce the tilting of the FPC main body 3;
[0052] When inserting, first insert the limit plate 9 into the limit sliding groove 8. At this time, the positions of the extension plate 5 and the FPC reinforcing plate 4 are aligned with the FPC connector 2. Then, push the FPC reinforcing plate 4 so that the FPC reinforcing plate 4 drives the FPC main body 3 to be inserted into the FPC connector 2. When unplugging, directly pull the FPC reinforcing plate 4 so that the FPC reinforcing plate 4 drives the FPC main body 3 to be separated from the FPC connector 2. Then, pull the FPC reinforcing plate 4 away from the circuit board main body 1 so that the limit sliding groove 8 is separated from the limit plate 9.
