[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] FPC connectors are made of flexible materials and can withstand bending and torsion, which makes them very suitable for applications with limited space or complex shapes. In addition, FPC connectors are usually designed to be pluggable, making the connection and disconnection between components simple and convenient, facilitating product maintenance and upgrades. In terms of technical background, the design and manufacture of FPC connectors involve multiple fields, including materials science, electronic engineering, and mechanical design. The density and versatility of connectors have made them increasingly widely used in modern electronic devices, such as touch screens, camera modules, and LED displays. At the same time, with the increasing demand for high-speed digital signals and high-speed data transmission, the design of FPC connectors has gradually developed towards higher data transmission rates and stronger anti-interference performance. As an important component for connecting flexible circuits, FPC connectors play a key role in modern electronic products, and the continuous advancement of their technology has promoted the development of smaller and higher-performance electronic devices.

[0028] Example 1:

[0029] Based on the technical defects of the existing technology such as poor connection effect and easy damage of the cable 5, please refer to Figure 1-Figure 7The utility model provides an FPC connector assembly, which adopts a pull-and-push method to disassemble and assemble the cable 5, which can ensure that the cable 5 is connected in place and firmly, and will not cause the cable 5 to become loose or have poor contact, thereby improving the stability of equipment operation and also improving the service life of the cable 5 and avoiding the problem of damage caused by excessive bending of the cable 5. The assembly includes a plastic body 1, a hinge seat 2 is fixed on the plastic body 1, a flip cover 3 is movably provided on the hinge seat 2, a movable groove 101 is opened on the plastic body 1, a connecting component 4 is movably provided in the movable groove 101, and a cable 5 is placed on the connecting component 4. A plurality of connecting terminals 7 adapted to the cable 5 are fixed on the inner wall of the movable groove 101, and two snap components 6 for fixing the flip cover 3 are fixed on the side wall of the plastic body 1; open the flip cover 3, place one end of the cable 5 on the connecting component 4, and after placement, close the flip cover 3, and use the flip cover 3 to squeeze and move the connecting component 4. At this time, one end of the cable 5 can be automatically pulled inward so that the cable 5 contacts the connecting terminal 7.

[0030] To connect cable 5, please refer to Figure 3-Figure 6 The connecting component 4 includes two springs 401 installed inside the movable groove 101, and one end of the two springs 401 is fixed with a movable seat 402 slidably set in the movable groove 101. The surface of the movable seat 402 is provided with a groove with the same thickness as the cable 5. Two positioning blocks 406 are fixed in the groove, and the two positioning blocks 406 are respectively clamped in the two positioning grooves 501 set on the cable 5. Both sides of the movable seat 402 are fixed with cylindrical sliders 403. One side of the slider 403 is slidably fitted with a pressure block 404. The pressure block The movable seat 404 is arranged in the slide groove 102 provided on the plastic body 1; the flip cover 3 is pressed down to make the pressure block 404 squeeze the slider 403 to move, and the slider 403 drives the movable seat 402 to move. Under the action of the positioning block 406, the positioning block 406 cooperates with the positioning groove 501 on the cable 5 to install and connect the cable 5 by pulling. Conversely, after opening the flip cover 3, the elastic force of the spring 401 can automatically push the movable seat 402 to move, thereby releasing the connection between the cable 5 and the FPC connector.

[0031] In order to facilitate the horizontal movement of the slider 403 , a through hole 103 is opened on the inner wall of the sliding groove 102 for the slider 403 to move left and right.

[0032] In order to ensure that the flip cover 3 can stably squeeze the pressing block 404 and to ensure that the pressing block 404 can move vertically along the inside of the slide groove 102, the top of the pressing block 404 is made into an arc shape and protrudes from the surface of the plastic body 1. A guide groove is opened on the side wall of the pressing block 404, and a guide block 405 is slidably arranged in the guide groove. The guide block 405 is fixed to the inner wall of the slide groove 102; the arc-shaped design can ensure that the top of the pressing block 404 is always in contact with the flip cover 3, so that when the flip cover 3 is closed, the pressing block 404 can be smoothly squeezed to move downward. At the same time, under the action of the guide block 405, the pressing block 404 will not deflect during movement, so that it is more stable when pushing the slider 403.

[0033] To solve the problem of fixing the flip cover 3, please refer to Figure 7 The buckle assembly 6 includes a fixing base 601 fixed to the side wall of the plastic body 1, and a buckle 603 is rotatably connected to the fixing base 601 through a rotating shaft 602, and a torsion spring 604 is sleeved on the rotating shaft 602; under the action of the torsion spring 604, the buckle 603 can be automatically connected to the flip cover 3, thereby fixing the flip cover 3.

[0034] Example 2:

[0035] When the connection terminal 7 loses its elasticity or is excessively deformed upward, the connection terminal 7 cannot contact the cable 5 after the cable 5 is installed, resulting in poor contact. To improve the connection stability, please refer to Figure 1 A plurality of protrusions 8 are fixed on the inner wall of the flip cover 3 and are located directly above the connecting terminals 7. When the flip cover 3 is closed, the protrusions 8 can exert an extrusion effect on the connecting terminals 7, ensuring that the connecting terminals 7 are in full contact with the flat cable 5, thereby improving the connection stability.

[0036] When dust enters the interior of the FPC connector, it will affect the connection between the connecting terminal 7 and the cable 5. To solve this problem, a sealing strip 9 is fixed on the inner wall of the flip cover 3. When the flip cover 3 is closed, the sealing strip 9 can fit on the cable 5 at the opening of the movable groove 101, thereby preventing dust or foreign matter from entering the plastic body 1. It has good dustproof performance and can ensure the stable and efficient connection of the cable 5.

[0037] Through the above embodiment, it can be seen that: when connecting the cable 5, the flip cover 3 is opened, and one end of the cable 5 is placed in the groove on the movable seat 402. After placement, the flip cover 3 is closed, and the flip cover 3 is pressed down to make the pressure block 404 squeeze the slider 403 to move. The slider 403 drives the movable seat 402 to move. Under the action of the positioning block 406, the positioning block 406 cooperates with the positioning groove 501 on the cable 5 to install and connect the cable 5 by pulling. Conversely, after opening the flip cover 3, the elastic force of the spring 401 can automatically push the movable seat 402 to move, thereby releasing the connection between the cable 5 and the FPC connector.
