Description

Technical Field

[0001] The utility model relates to the technical field of FPC, and more specifically to a high-reliability FPC connection structure. Background Art

[0002] With the popularization of electronic devices and the improvement of their intelligence, touch screens, as an intuitive and convenient way of human-computer interaction, have been widely used in mobile phones, tablet computers, vehicle systems, industrial control and other fields. The performance of the touch screen FPC (flexible printed circuit board) connector, as a bridge between the touch screen and the motherboard, directly affects the operating stability of the entire electronic device and the user experience. The common touch screen FPC connector connection methods on the market currently include plug-in, welding and snap-on. The plug-in method realizes connection through direct plug-in and has the advantage of simple operation. However, since the copper surface of the plug-in end is directly exposed, it is easy to wear after multiple plug-ins and pull-outs, affecting the connection effect and stability. The welding method directly connects the FPC to the motherboard through welding technology. Although the cost is low, the welding process is complicated, which is not conducive to rapid replacement and maintenance, and the welding points are prone to breakage or loosening in harsh environments.

[0003] As an emerging connector connection method, the buckle connection method realizes a stable connection between the FPC and the motherboard through the structural design of the male and female buckles. This method is not only easy to operate, but also avoids the problem of exposed copper surface and reduces the wear of the connection end. However, the buckle connection method also has some limitations. In some working environments with large vibration and impact, such as vehicle-mounted systems, industrial control and other fields, the connection between the male and female buckles may be loosened by external forces, resulting in connection failure or poor contact. Therefore, we have made improvements to this and proposed a high-reliability FPC connection structure.

[0004] For example, a Chinese patent (publication number CN219513369U) discloses an FPC transfer waterproof connector, and its specification discloses: FPC (flexible circuit board) is used instead of wires as a transfer line, but due to unreasonable structural design, the structural stability of the entire connector is poor, especially the joint between the FPC and the connector body is not stable enough, resulting in poor reliability of the connector. In addition, the PIN pin and the terminal are usually connected by riveting and pressing, which is easy to loosen, which also causes poor reliability. Utility Model Content

[0011] As an improved manner of the utility model, the reinforcing portion includes a reinforcing plate fixedly mounted on a side of the PCB board body away from the FPC body, and reinforcing strips are fixedly connected to both sides of the bottom of the reinforcing plate.

[0013] As an improvement of the utility model, one end of the limiting plate away from the connecting plate extends out of the reinforcing plate.

[0014] As an improvement of the utility model, a clamping strip is fixedly connected to one side of the limit plate close to the reinforcing plate, and a clamping slot for plugging with the clamping strip is provided on the reinforcing plate.

[0015] As an improvement of the utility model, a lifting plate is fixedly connected to one side of the two connecting plates that are away from each other, the position of the lifting plate corresponds to the position of the reinforcing strip, and the end of the connecting shaft is connected to the lifting plate.

[0016] As an improvement of the utility model, a circular groove with the connecting shaft as the center is opened on the side of the connecting seat, and a torsion spring located in the circular groove is sleeved on the outer surface of the connecting shaft. The two ends of the torsion spring are respectively fixedly connected to the connecting shaft and the circular groove.

Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] As described in the background technology, the buckle connection method is a new connector connection method. Through the structural design of male and female buckles, a stable connection between FPC and motherboard is achieved. This method is not only easy to operate, but also avoids the problem of exposed copper surface and reduces the wear of the connection end. However, the buckle connection method also has some limitations. In some working environments with large vibration and impact, such as vehicle-mounted systems, industrial control and other fields, the connection between male and female buckles may be loosened by external forces, resulting in connection failure or poor contact. Therefore, we have made improvements on this and proposed a high-reliability FPC connection structure.

[0031] In order to solve this technical problem, the utility model provides a high-reliability FPC connection structure.

[0032] Specifically, please refer to Figure 1-Figure 5 , the high reliability FPC connection structure specifically includes:

[0033] An FPC body 1 and a PCB board body 2, wherein an FPC connector 101 is arranged on the FPC body 1, and a PCB connector 201 is arranged on the PCB board body 2, the PCB connector 201 and the FPC connector 101 are buckled with each other, and a reinforcement piece is arranged between the PCB board body 2 and the FPC body 1, and the reinforcement piece is used for reinforcing the PCB connector 201 and the FPC connector 101 after being buckled with each other.

[0034] The high-reliability FPC connection structure provided by the utility model has a reinforcement piece arranged between the PCB board body 2 and the FPC body 1. The reinforcement piece can reinforce the PCB connector 201 and the FPC connector 101 after they are buckled together, thereby increasing the fixing force between the PCB connector 201 and the FPC connector 101, and effectively preventing the PCB connector 201 and the FPC connector 101 from loosening under vibration or impact.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] Embodiment 1 of the utility model high reliability FPC connection structure

[0039] Please refer to Figure 1-Figure 5 The high-reliability FPC connection structure of the utility model includes: an FPC body 1 and a PCB board body 2, an FPC connector 101 is arranged on the FPC body 1, and a PCB connector 201 is arranged on the PCB board body 2, the PCB connector 201 and the FPC connector 101 are buckled with each other, and a reinforcing member is arranged between the PCB board body 2 and the FPC body 1, and the reinforcing member is used for reinforcing the PCB connector 201 and the FPC connector 101 after being buckled. By arranging the reinforcing member between the PCB board body 2 and the FPC body 1, the reinforcing member can reinforce the PCB connector 201 and the FPC connector 101 after being buckled, thereby increasing the fixing force between the PCB connector 201 and the FPC connector 101, and effectively preventing the PCB connector 201 and the FPC connector 101 from loosening under vibration or impact.

[0040] Embodiment 2 of the utility model high reliability FPC connection structure

[0041] The high reliability FPC connection structure of the utility model is further as follows: Figure 1-Figure 4 As shown, the reinforcement includes a first Velcro 3 connected to the FPC body 1 and a second Velcro 4 connected to the PCB board body 2, the first Velcro 3 and the second Velcro 4 adhere to each other, the first Velcro 3 and the second Velcro 4 are made of 3M Velcro, and the first Velcro 3 and the second Velcro 4 can adhere to each other.

[0042] Furthermore, the first Velcro 3 and the second Velcro 4 cooperate to achieve reinforcement of the PCB connector 201 and the FPC connector 101 after buckling, thereby enhancing the connectivity between the FPC body 1 and the PCB board body 2. The 3M Velcro is connected by flexible spines, and can withstand a certain range of vibration or shaking without falling off after being fitted, so that the connection between the FPC body 1 and the PCB board body 2 can adapt to relatively harsh working environments, thereby improving the reliability and stability of the touch screen. At the same time, the reusability of the 3M Velcro makes the installation and disassembly process more convenient, reducing the cost of maintenance and replacement. In addition, the design also retains the original ease of operation of the buckling method, allowing users to easily achieve quick connection and disconnection during use, thereby improving the overall user experience. When in use, buckle the PCB connector 201 and the FPC connector 101 so that the first Velcro 3 and the second Velcro 4 are bonded together.

[0043] Embodiment 3 of the utility model high reliability FPC connection structure

[0044] The high reliability FPC connection structure of the utility model is further as follows: Figure 5-Figure 7 As shown, the reinforcement member is a reinforcement part 5, and the reinforcement part 5 is arranged between the FPC body 1 and the PCB board body 2. The arrangement of the reinforcement part 5 can reinforce the PCB connector 201 and the FPC connector 101 after they are buckled together, thereby increasing the fixing force between the PCB connector 201 and the FPC connector 101, and effectively preventing the PCB connector 201 and the FPC connector 101 from loosening under vibration or impact.

[0045] Further, such as Figure 5-Figure 7 As shown, the reinforcement part 5 includes a reinforcement plate 501 fixedly installed on the side of the PCB board body 2 away from the FPC body 1, and reinforcement strips 502 are fixedly connected to both sides of the bottom of the reinforcement plate 501. The reinforcement plate 501 and the reinforcement strips 502 can reinforce the part of the PCB board body 2 close to the PCB connector 201, thereby facilitating the plugging and unplugging of the PCB connector 201.

[0046] Further, such as Figure 6 As shown, the reinforcement part 5 also includes a connection seat 503 fixedly installed on the FPC body 1, and a connection shaft 504 is inserted and connected to the connection seat 503. Two connection plates 507 are fixedly sleeved on the outer surface of the connection shaft 504. A limit plate 509 is fixedly connected between the tops of the two connection plates 507, and the limit plate 509 is in contact with a side of the reinforcement plate 501 away from the PCB board body 2. The limit plate 509 presses the reinforcement plate 501 to reinforce the buckle between the PCB connector 201 and the FPC connector 101.

[0047] Further, such as Figure 5 As shown, one end of the limiting plate 509 away from the connecting plate 507 extends out of the reinforcing plate 501 , so that the one end of the limiting plate 509 away from the connecting plate 507 is suspended in the air, so as to facilitate the rotation of the limiting plate 509 .

[0048] Further, such as Figure 5-Figure 7 As shown, a clamping strip 510 is fixedly connected to one side of the limit plate 509 close to the reinforcing plate 501, and a clamping slot 511 is provided on the reinforcing plate 501 to be plugged into the clamping strip 510. The mutual cooperation between the clamping strip 510 and the clamping slot 511 can improve the limiting effect of the limit plate 509 on the reinforcing plate 501, thereby improving the reinforcement of the PCB connector 201 and the FPC connector 101 after buckling, and reducing the loosening of the PCB connector 201 and the FPC connector 101 under vibration or impact after buckling.

[0049] Further, such as Figure 5-Figure 7 As shown, a lifting plate 508 is fixedly connected to one side of the two connecting plates 507 that are away from each other. The position of the lifting plate 508 corresponds to the position of the reinforcing strip 502, and the end of the connecting shaft 504 is connected to the lifting plate 508. When the limit plate 509 is rotated, the lifting plate 508 can be driven to rotate. By pushing the reinforcing strip 502 to lift up through the lifting plate 508, the PCB connector 201 and the FPC connector 101 can be loosened, thereby facilitating the separation of the PCB connector 201 and the FPC connector 101.

[0050] Further, such as Figure 8 As shown, a circular groove 505 with the connecting shaft 504 as the center is formed on the side of the connecting seat 503, and a torsion spring 506 located in the circular groove 505 is sleeved on the outer surface of the connecting shaft 504. The two ends of the torsion spring 506 are respectively fixedly connected to the connecting shaft 504 and the circular groove 505. The force of the torsion spring 506 can limit the limiting plate 509 through the connecting shaft 504 and the connecting plate 507, so that the limiting plate 509 can press the reinforcing plate 501.

[0051] When in use, after the PCB connector 201 is buckled with the FPC connector 101, the force of the torsion spring 506 limits the limit plate 509 through the connecting shaft 504 and the connecting plate 507, so that the limit plate 509 can press the reinforcing plate 501, and the insertion of the clamping strip 510 and the clamping slot 511 enables the reinforcing part 5 to fix the position of the PCB board body 2, so as to improve the firmness of the connection between the PCB connector 201 and the FPC connector 101. When it is necessary to separate the PCB connector 201 from the FPC connector 101, the limit plate 509 is rotated to lift the lifting plate 509. 08 is rotated to contact with the reinforcing strip 502, and the reinforcing strip 502 is pried by the lifting plate 508 so that the reinforcing plate 501 drives the PCB board body 2 away from the FPC body 1, thereby loosening the connection between the PCB connector 201 and the FPC connector 101, so as to facilitate the separation of the PCB connector 201 and the FPC connector 101. During installation, the limiting plate 509 is rotated to stand upright, and then the PCB connector 201 and the FPC connector 101 are buckled together, and the limiting plate 509 is rotated toward the reinforcing plate 501 so that the card strip 510 and the card slot 511 are plugged together.

[0052] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model.
