Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC technology, and in particular to an FPC structure that facilitates accurate insertion. Background Technology
[0002] Flexible printed circuit boards (PCBs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending properties.
[0003] With the explosive growth of wearable devices, flexible displays, and smart devices, the demand for flexible circuit boards has increased significantly, and they are being used more and more widely in the industry. For example, the design of plug-in FPCs is currently used in many display modules. When plugging in the corresponding connectors of the whole machine, there are certain insertion depth requirements. If the insertion depth is too shallow, it is easy to fall off or cause poor contact. If the insertion depth is too deep, it is easy to squeeze the plug-in end of the FPC, damage the plug-in FPC, and cause the module to be unable to connect and apply. Therefore, an FPC structure that facilitates accurate insertion is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide an FPC structure that facilitates accurate insertion in order to address the aforementioned technical problems. This involves designing a rigid support on the back of a conventional FPC to ensure accurate control of the actual insertion depth.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] An FPC structure for easy and accurate insertion includes an FPC connector and an FPC. The front end of the FPC has a plug end with an insertion area and an exposed area. The FPC is also provided with a rigid support member. One end of the rigid support member facing the FPC connector is flush with the direction of the insertion area facing the end of the FPC. The rigid support member can limit the insertion depth of the insertion area.
[0007] Furthermore, the rigid support member includes a rigid plate;
[0008] The rigid plate has two parts, which are distributed on both sides of the FPC surface and fixed.
[0009] Furthermore, one end of the rigid plate has a limiting end, and the junction of the insertion area and the exposed area is flush with the limiting end of the rigid plate.
[0010] Furthermore, the surface of the rigid plate has a sloping groove, which causes the cross-section of the rigid plate to be a "right-angled triangle".
[0011] Furthermore, both rigid plates have an outwardly extending wrapping portion that covers and wraps around the outside of the FPC.
[0012] Furthermore, the junction between the wrapping part and the rigid plate is formed with a rounded chamfer.
[0013] Furthermore, anti-slip grooves are formed on the surface of the package portion, and the plurality of anti-slip grooves are equally spaced along the length direction of the FPC.
[0014] Furthermore, both rigid plates are jointly fixed with a rigid connecting plate, which is integrally injection molded with the rigid plates;
[0015] The rigid connecting plate and the rigid plate are both made of PI material.
[0016] Furthermore, the rigid connecting plate is connected to the edge of the rigid plate and is flush with the limiting end, and one side of the rigid connecting plate and the limiting end together form a limiting platform.
[0017] Furthermore, the rigid support is located on the back of the FPC.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] The FPC structure provided by this utility model facilitates accurate insertion. It features a rigid support near the insertion end of a conventional FPC. When the FPC is inserted into the FPC connector, the rigid support end acts as an obstacle on the outside of the FPC connector, thus preventing the insertion end of the FPC from being inserted too deeply and causing damage. At the same time, by observing the gap between the rigid support end and the FPC connector, it is possible to determine whether the FPC insertion end is properly inserted, avoiding poor contact problems.
[0020] Furthermore, since the rigid support component itself provides a certain degree of support, it is convenient for operators to pick up and insert the FPC during the insertion process, reducing the situation where the FPC itself is too soft and inconvenient to operate.
[0021] The design of the inclined groove makes the surface of the rigid plate non-planar, which facilitates the operator to exert force better during the insertion process. At the same time, with the extension of the wrapping part, it can wrap the side of the FPC, which not only increases the effective contact area between the rigid support and the FPC, ensuring the strength of the connection after assembly, but also increases the effective operating area of the operator's hands, making it easier to grip the FPC when inserting it.
[0022] The anti-slip grooves on the packaging section provide a more effective anti-slip surface when the operator grips the packaging section with their fingertips, ensuring stability during the insertion process and reducing slippage.
[0023] By using a rigid connecting plate, two rigid plates on the FPC surface can be connected to form an integrated connection structure, which improves the overall support strength. This allows for more effective force transmission during insertion and also makes it easier to judge the insertion status of the FPC insertion end by observing the gap between the limiting platform and the FPC connector, ensuring the accuracy of insertion.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0035] As described in the background section, when an FPC is inserted into the corresponding connector of the whole machine, there are certain insertion depth requirements. If the insertion depth is too shallow, it is easy to fall off or cause poor contact; while if the insertion depth is too deep, it is easy to squeeze the insertion end of the FPC, damage the FPC, and cause the module to be unable to connect and apply.
[0036] To solve this technical problem, this utility model provides an FPC structure that facilitates accurate insertion and is applied to FPCs.
[0037] For details, please refer to Figures 1-5 The FPC structure that facilitates accurate insertion specifically includes an FPC connector 1 and an FPC 2. The front end of the FPC 2 has a plug end 21, and the plug end 21 has an insertion area 22 and an exposed area 23. The FPC 2 is also provided with a rigid support 3. One end of the rigid support 3 facing the FPC connector 1 is flush with the direction of the insertion area 22 facing the end of the FPC 2. The rigid support 3 can limit the insertion depth of the insertion area 22.
[0038] The FPC structure provided by this utility model facilitates accurate insertion. A rigid support 3 is designed near the insertion end 21 of the conventional FPC2. After the FPC2 is inserted into the FPC connector 1, the rigid support 3 acts as an obstacle on the outside of the FPC connector 1, thus preventing the insertion end 21 of the FPC2 from being inserted too deeply and easily causing damage. At the same time, by observing the gap between the end of the rigid support 3 and the FPC connector 1, it can be determined whether the insertion end of the FPC2 is inserted in place, avoiding poor contact problems.
[0039] Furthermore, since the rigid support component itself provides a certain degree of support, it is convenient for operators to pick up and insert the FPC during the insertion process, reducing the situation where the FPC itself is too soft and inconvenient to operate.
[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] Example 1
[0044] Please refer to Figure 1 and Figure 2 As shown, an FPC structure that facilitates accurate insertion includes an FPC connector 1 and an FPC 2. The front end of the FPC 2 has a plug-in end 21, and the plug-in end 21 has an insertion area 22 and an exposed area 23. The FPC 2 is also provided with a rigid support 3. One end of the rigid support 3 facing the FPC connector 1 is flush with the direction of the insertion area 22 facing the end of the FPC 2. The rigid support 3 can limit the insertion depth of the insertion area 22.
[0045] The rigid support 3 includes a rigid plate 31, such as... Figure 2 As shown, there are two rigid plates 31, which are distributed on both sides of the surface of the FPC2 and fixed. The outer sides of the two rigid plates 31 correspond to the edge of the FPC2, so that they do not protrude from the outer side of the FPC2 and affect the subsequent assembly and application of the module.
[0046] like Figure 2 As shown, one end of the rigid plate 31 has a limiting end 32, and the junction of the insertion area 22 and the exposed area 23 is flush with the limiting end 32 of the rigid plate 31.
[0047] In this embodiment, the connection between the insertion area 22 and the exposed area 23 is marked with a dashed line. The area on one side of the dashed line is the insertion area 22, which is to be completely inserted into the FPC connector 1 to achieve the connection function. The area on the other side of the dashed line is the exposed area 23, which is to be connected after the insertion area 22 is completely inserted into the FPC connector 1, while the exposed area 23 is still exposed to the outside.
[0048] Specifically, when inserting FPC2 into FPC connector 1, the operator holds the rigid plate 31 on FPC2, aligns the insertion end 21 with the opening of FPC connector 1, and inserts it. During the insertion process, the rigid plate 31 facilitates the application of force. At the same time, after it is fully inserted, the limiting end 32 on the rigid plate 31 can form an obstruction between it and the outer end of FPC connector 1, thereby preventing further insertion of FPC2 and ensuring the accuracy of insertion.
[0049] As a further optimization of this embodiment: the surface of the rigid plate 31 has a sloping groove 34, and the cross section of the rigid plate 31 is a "right triangle" due to the action of the sloping groove 34.
[0050] Example 2
[0051] The FPC structure provided in Embodiment 1, which facilitates accurate insertion, is further optimized, specifically, as follows: Figure 3 As shown, both rigid plates 31 have an outwardly extending wrapping portion 310. The wrapping portion 310 covers and wraps the outside of the FPC2. The design of the wrapping portion 310 increases the effective contact area between the rigid support 3 and the FPC2, ensuring that the rigid support 3 is firmly connected after assembly, while also increasing the effective operating area of the operator's hands.
[0052] The junction between the wrapping part 310 and the rigid plate 31 is formed with a rounded chamfer 311, which improves the overall aesthetics of the rigid support 3.
[0053] Anti-slip grooves 312 are provided on the surface of the wrapping part 310. The multiple anti-slip grooves 312 are evenly spaced along the length direction of the FPC2. Due to the action of the anti-slip grooves 312, when the rigid support 3 is picked up and inserted, the operator's fingertips can be partially pressed into the anti-slip grooves 312, so that the hand and the rigid support 3 form a non-planar contact, thereby improving the effective friction of the contact surface and avoiding the problem of slippage during the insertion process.
[0054] Example 3
[0055] The FPC structure provided in Embodiment 1 or 2 for accurate insertion is further optimized, such as... Figure 4 and Figure 5 As shown, the two rigid plates 31 are jointly fixed with a rigid connecting plate 35. The rigid connecting plate 35 and the rigid plate 31 are integrally injection molded. In this embodiment, the two rigid plates 31 can be connected by the added rigid connecting plate 35 to form an integral connection structure. This makes it convenient to simultaneously pick up multiple rigid plates 31 and the wrapping part 310 by picking up the rigid connecting plate 35 when assembling the rigid plates 31, which facilitates their assembly and connection on the FPC2.
[0056] Furthermore, during the insertion process of FPC2, the support of the rigid connecting plate 35 can prevent the area between the rigid plates 31 from twisting and deforming, thus avoiding damage to FPC2 and allowing the insertion force to be transmitted more effectively, further facilitating the insertion operation.
[0057] The rigid connecting plate 35 and the rigid plate 31 are both made of PI, which in this embodiment refers to polyimide.
[0058] As a further optimization of this embodiment, such as Figure 5 As shown, the rigid connecting plate 35 is connected to the edge of the rigid plate 31 and is flush with the limiting end 32. One side of the rigid connecting plate 35 and the limiting end 32 together form a limiting platform 36. In this way, when the plug end 21 on the FPC2 is aligned with the insertion port on the FPC connector 1, the gap between the limiting platform 36 and the FPC connector 1 is observed to determine whether it is plugged in properly. At the same time, the limiting platform 36 can also prevent the FPC2 from being inserted too deeply. Since the area on one side of the limiting platform 36 (insertion area 22) is completely inserted into the FPC connector 1, the connection between the plug end 21 on the FPC2 and the FPC connector 1 can be completed.
[0059] The rigid support 3 is located on the back of the FPC2. In this embodiment, the rigid support 3 is located on the back of the FPC2 (excluding the wrapping part). However, in actual applications, if it does not affect the application of the FPC2 itself, the rigid support 3 can also be located on the front of the FPC2. It can be flexibly adjusted according to the actual application scenario.
