Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] In this embodiment, refer to Figures 1-7 The specific implementation of the FPC connector with a self-locking structure includes a base 1, on which a rotatable pressure plate 2 is mounted. The pressure plate 2 is provided with a pressing part 7. Rotating parts 8 at both ends of the pressing part 7 are installed in the guide groove 9 of the base 1. The inclined design of the guide groove 9 allows the rotating part 8 to not only rotate in the guide groove 9, but also to move along the guide groove 9, thus driving the pressure plate 2 to move.

[0024] Furthermore, the base 1 contains conductive terminals 3 and ground terminals 4 that mate with the pressure plate 2. The conductive terminals 3 have pre-pressing grooves 10 and clamping grooves 11 that are staggered in height. The pressing part 7 is accommodated within the pre-pressing groove 10, and its lower end is used to press the flexible circuit board 16. By closing the pressure plate 2, the flexible circuit board 16 is fixed inside the connector, initially under a small pre-pressure to ensure initial connection between the flexible circuit board 16 and the contacts on the connector, reducing initial wear. The ground terminals 4 are located on the left and right sides inside the base 1, connecting the circuit to the ground to ensure electrical safety.

[0025] Furthermore, the pressure plate 2 is pulled outward, causing the pressing part 7 to move from the higher pre-pressure groove 10 to the lower clamping groove 11. The lower clamping groove 11 is designed to further compress the pressing part 7 downward on the basis of the pre-pressure groove 10, so as to ensure a stable electrical connection between the flexible circuit board 16 and the connector contacts, ensure good contact during long-term use and under various environmental conditions, and improve the transmission efficiency and quality of current signals.

[0026] Furthermore, a ridge 12 is provided between the pre-pressing groove 10 and the tightening groove 11. The design of the ridge 12 ensures that the pressing part 7 can be accurately positioned between the pre-pressing groove 10 and the tightening groove 11, and avoids the pressing part 7 from shifting during operation.

[0027] And the end of the pressing groove 11 is provided with downward extending stopper 17, the setting of stopper 17 not only prevents the excessive displacement of pressing part 7, and when the closing of the pressing plate 2, stopper 17 works with pressing groove 11, ensure that the pressing part 7 moves stably in the predetermined track.This design increases the reliability of mechanical structure, reduces the risk of failure due to improper operation or mechanical wear.

[0028] Further, the two sides of the pressing plate 2 are provided with fixed column 5, the base 1 is provided with clamping groove 15, so that the fixed column 5 is accommodated in the clamping groove 15 when the pressing plate 2 is closed, at this time the pressing plate 2 is in the open state.Further, the fixed column 5 will pass through the positioning boss 14 and be fixed below the guide part 6 when the pressing plate 2 is pulled outwards.Therefore the fixed column 5 cannot easily slide, so that the fixed column 5 can be stably kept in the predetermined position, thereby ensuring the stability and reliability of the pressing plate 2.The clamping groove 15 ensures the stability of the connector during operation, ensures that the pressing plate 2 will not be opened accidentally, thereby avoiding the accidental falling of the flexible circuit board 16.The whole process is simple and fast, and improves the long-term reliability of the connector.The user only needs to push the pressing plate 2 inwards, and the fixed column 5 will be separated from the clamping groove 15, thereby releasing the fixing of the pressing plate 2.

[0029] In addition, the design of the guide part 6 makes the guide part 6 push the fixed column 5 to the clamping groove 15 when the pressing plate 2 is closed, ensuring that the fixed column 5 can accurately enter the clamping groove 15 during the closing process of the pressing plate 2, so that the action of closing the pressing plate 2 is smoother, improving the user experience.

[0030] The utility model discloses the beneficial effects of: through setting the downward inclined guide groove 9 on the base 1, the pressing plate 2 can be turned over and moved along the inclined direction of the guide groove 9.The pressing plate 2 can apply pressure to the flexible circuit board 16 downward, ensuring the tightness of the connection and the stability of the contact, effectively reducing the signal transmission problem caused by poor contact, and after the flexible circuit board 16 is pressed, the pressing plate 2 can be clamped into the clamping groove 15 on both sides of the base 1 through the fixed column 5, effectively avoiding the loosening of the pressing plate 2, thereby forming a stable fixing effect.
