[0034] 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.

[0035] Embodiment 1 of the utility model anti-slip FPC structure

[0036] Please refer to Figure 1-Figure 6 The utility model anti-dropping FPC structure comprises: a PCB circuit board 2, an FPC connector 1 is arranged on the PCB circuit board 2, and the FPC connector 1 is connected to an FPC body 4, an anti-dropping component is arranged between the FPC body 4 and the PCB circuit board 2, and the anti-dropping component comprises a reinforcement module 3 arranged on the PCB circuit board 2 and an FPC reinforcement plate 5 fixedly installed on the FPC body 4, and the reinforcement module 3 realizes the reinforcement of the FPC body 4 by fixing the FPC reinforcement plate 5, and the FPC body 4 can be reinforced by the mutual cooperation of the reinforcement module 3 and the FPC reinforcement plate 5, so as to reduce the loose connection between the FPC body 4 and the FPC connector 1, effectively prevent the FPC body 4 from falling off, and improve the stability and reliability of the equipment;

[0037] The materials commonly used for the FPC reinforcing plate 5 are high-performance materials such as glass fiber or polyimide. These materials have excellent mechanical strength, electrical properties, heat resistance and chemical stability, and can effectively improve the durability and reliability of the FPC reinforcing plate 5, so as to adapt to various harsh use environments; among them, glass fiber reinforced materials are widely used in occasions that need to withstand high mechanical stress and electrical requirements due to their high strength, high modulus, low thermal expansion coefficient and good electrical insulation properties. They are usually used to enhance the mechanical strength of the FPC reinforcing plate 5 to prevent it from breaking or being damaged during bending, twisting or stretching.

[0038] Furthermore, the FPC reinforcement plate 5 is detachably connected to the reinforcement module 3 to achieve separation of the FPC body 4 and the FPC connector 1. That is, when the FPC body 4 needs to be separated from the FPC connector 1, the fixation of the FPC reinforcement plate 5 by the contact reinforcement module 3 can prevent the reinforcement module 3 and the FPC reinforcement plate 5 from affecting the separation of the FPC body 4 and the FPC connector 1.

[0039] Embodiment 2 of the utility model anti-dropping FPC structure

[0040] Please refer to Figure 1-Figure 6The utility model anti-dropping FPC structure comprises: a PCB circuit board 2, an FPC connector 1 is arranged on the PCB circuit board 2, and the FPC connector 1 is connected to an FPC body 4, an anti-dropping component is arranged between the FPC body 4 and the PCB circuit board 2, and the anti-dropping component comprises a reinforcement module 3 arranged on the PCB circuit board 2 and an FPC reinforcement plate 5 fixedly installed on the FPC body 4, and the reinforcement module 3 realizes the reinforcement of the FPC body 4 by fixing the FPC reinforcement plate 5, and the FPC body 4 can be reinforced by the mutual cooperation of the reinforcement module 3 and the FPC reinforcement plate 5, so as to reduce the loose connection between the FPC body 4 and the FPC connector 1, effectively prevent the FPC body 4 from falling off, and improve the stability and reliability of the equipment;

[0041] The materials commonly used for the FPC reinforcing plate 5 are high-performance materials such as glass fiber or polyimide. These materials have excellent mechanical strength, electrical properties, heat resistance and chemical stability, and can effectively improve the durability and reliability of the FPC reinforcing plate 5, so as to adapt to various harsh use environments; among them, glass fiber reinforced materials are widely used in occasions that need to withstand high mechanical stress and electrical requirements due to their high strength, high modulus, low thermal expansion coefficient and good electrical insulation properties. They are usually used to enhance the mechanical strength of the FPC reinforcing plate 5 to prevent it from breaking or being damaged during bending, twisting or stretching.

[0042] Furthermore, the FPC reinforcement plate 5 is detachably connected to the reinforcement module 3 to achieve separation of the FPC body 4 and the FPC connector 1. That is, when the FPC body 4 needs to be separated from the FPC connector 1, the fixation of the FPC reinforcement plate 5 by the contact reinforcement module 3 can prevent the reinforcement module 3 and the FPC reinforcement plate 5 from affecting the separation of the FPC body 4 and the FPC connector 1.

[0043] Further, such as Figure 1-Figure 5 As shown, the reinforcement module 3 includes two fixing parts, both of which are installed on the top of the PCB circuit board 2, and the two fixing parts are detachably connected to the two ends of the FPC reinforcement plate 5 respectively. By fixing the two ends of the FPC reinforcement plate 5 with the two fixing parts, the stability of the fixation of the FPC reinforcement plate 5 can be improved, and the fixing effect of the FPC body 4 can be further improved, reducing the loosening between the FPC body 4 and the FPC connector 1.

[0044] Furthermore, the two fixing parts are used to cooperate with the two ends of the FPC reinforcing plate 5 to limit the FPC body 4, so as to prevent the FPC body 4 from falling off, thereby effectively preventing the FPC body 4 from falling off and improving the stability and reliability of the equipment.

[0045] Further, such as Figure 2-Figure 5As shown, the fixing portion includes a card holder housing 301 located on the top of the PCB circuit board 2 , and the card holder housing 301 is located on the side of the FPC reinforcing plate 5 .

[0046] Further, such as Figure 5-Figure 6 As shown, a groove 302 is provided on the card holder shell 301, and a main card holder 305 is inserted into the groove 302. A fixing column 306 is fixedly connected to the bottom end of the main card holder 305. The bottom end of the fixing column 306 passes through the card holder shell 301 and is fixedly connected to the PCB circuit board 2. The card holder shell 301 is fixed by the connection between the fixing column 306 and the PCB circuit board 2.

[0047] Further, such as Figure 5-Figure 6 As shown, a second transverse groove 307 is provided on a side of the main card seat 305 away from the FPC connector 1, and a first transverse groove 303 is provided on a side of the card seat shell 301 away from the FPC connector 1. The position of the first transverse groove 303 corresponds to the position of the second transverse groove 307, and the FPC reinforcement plate 5 is inserted between the second transverse groove 307 and the first transverse groove 303. The setting of the first transverse groove 303 and the second transverse groove 307 facilitates the connection between the FPC reinforcement plate 5 and the reinforcement module 3 to adapt to the fixing requirements of the FPC reinforcement plate 5.

[0048] Further, such as Figure 5-Figure 6 As shown, the top of the main card seat 305 is threadedly connected with a fastening bolt 308, the bottom end of the fastening bolt 308 penetrates into the second transverse groove 307 and contacts with the top of the FPC reinforcement plate 5, and the FPC reinforcement plate 5 is fixed by the fastening bolt 308 to achieve the fixation of the FPC body 4. The card seat shell 301 and the groove 302 are made of materials with different hardness. The card seat shell 301 uses a harder plastic material to prevent the groove 302 from bursting and failing due to the locking of the fastening bolt 308, thereby extending the service life of the entire structure.

[0049] Further, such as Figure 5 As shown, a circular longitudinal through hole 304 is opened on the top of the card seat shell 301, and the circular longitudinal through hole 304 is connected to the groove 302, and the top end of the fastening bolt 308 is located in the circular longitudinal through hole 304. The setting of the circular longitudinal through hole 304 can prevent the card seat shell 301 from interfering with the rotation and lifting of the fastening bolt 308.

[0050] When using, refer to Figure 2, use a screwdriver to rotate the fastening bolt 308 so that the fastening bolt 308 rises and separates from the FPC reinforcing plate 5, pull the FPC reinforcing plate 5 and the FPC body 4 so that the FPC reinforcing plate 5 is separated from the first transverse slot 303, and the FPC body 4 can be separated from the FPC connector 1. During installation, the FPC body 4 is connected to the FPC connector 1, and the FPC reinforcing plate 5 is inserted into the first transverse slot 303 and the second transverse slot 307, and the fastening bolt 308 is rotated with a screwdriver so that the fastening bolt 308 descends and connects with the FPC reinforcing plate 5. The FPC reinforcement plate 5 is clamped and fixed, and then the FPC body 4 is fixed, reducing the loose connection between the FPC body 4 and the FPC connector 1, effectively preventing the FPC body 4 from falling off, and improving the stability and reliability of the equipment. Through the design of the above structure, the FPC body 4 is double locked by the reinforcement module 3, the FPC reinforcement plate 5 and the FPC connector 1. It can resist severe vibration and accidental pulling, greatly reducing the risk of falling off, ensuring the stable operation of the display device in harsh environments, and is suitable for various demanding application scenarios.
