The positioning piece 4 abuts against the cover plate 2 to prevent the cover plate 2 from being lifted.

[0026] Furthermore, the pins 3 are inserted and fixed from the rear of the housing 1. The cover plate 2 and the pins 3 are hinged to each other. Convex platforms 21 are further provided at the left and right ends of the cover plate 2. The convex platforms 21 are fitted into the grooves 16 to apply resistance to the cover plate 2 in the lifting direction.

[0027] Specifically, the pin 3 is U-shaped. The upper end of the pin 3 is inserted into the docking groove 15 of the housing 1, and the lower end of the pin 3 is inserted into the limiting groove 14 of the housing 1. At the upper and lower ends of the closed end of the pin 3, there are stop blocks 32 extending respectively. The height of the stop block 32 is greater than the height from the top plate 13 to the bottom plate 11 of the housing 1. When the pin 3 is inserted into the housing 1, the pin 3 moves along the Z-axis. When the stop block 32 abuts against the top plate 13 and the bottom plate 11 of the housing 1, the pin 3 is installed in place. An inner groove 31 is also provided at the upper end of the pin 3. A rotating rod 22 is integrally formed on the cover plate 2. The rotating rod 22 is engaged in the inner groove 31 at the upper end of the pin 3. The rotating rod 22 can drive the cover plate 2 to rotate along the inner groove 31. The rotation angle of the cover plate 2 is 0° - 120°. The relative end of the cover plate 2 connected to the pin 3 is stepped. The boss 21 is provided on one side of the outer step. When the cover plate 2 is closed, the boss 21 is engaged with the groove 16 on the side plate 12 to achieve the first-stage positioning connection.

[0028] Further, the positioning piece 4 includes a first bottom plate 41, a second bottom plate 42 and a first side plate 43. The positioning piece 4 is L-shaped. An extension piece 44 is also provided on the first side plate 43. The positioning piece 4 is connected to the housing 1 in a pluggable manner. Among them, the inner sides of the first bottom plate 41 and the second bottom plate 42 abut against the bottom surface of the side plate 12 of the housing 1, and the inner side of the first side plate 43 abuts against the inner side of the side plate of the housing 1. A U-shaped groove is provided at the connection of the first bottom plate 41, the second bottom plate 42 and the first side plate 43. Correspondingly, a break groove 17 is formed between the bottom plate 11 and the side plate 12. A jack is provided at the connection of the top plate 13, the bottom plate 11 and the side plate 12. When the first bottom plate 41 abuts against the bottom of the side plate 12, the positioning piece 4 moves along the break groove 17 in the Z-axis direction. When the end of the first side plate 43 is inserted into the jack 18, the installation of the positioning piece 4 is completed. The extension piece 44 is an elastic bending metal sheet. When the cover plate 2 is closed, the extension piece 44 is closely attached to the inner step of the cover plate 2 to achieve the effect of double-stage positioning connection.

[0029] Working principle: When assembling this double-positioning FPC connector, insert the pin 3 into the limiting groove 14 and the docking groove 15 of the housing 1, install the cover plate 2 on the inner groove 31 of the pin 3, and insert the positioning piece 4 into the bottom of the housing 1. During use, rotate the cover plate 2 counterclockwise to open it, place the FPC cable into the limiting groove 14 on the bottom plate 11 of the housing 1 and connect it to the bottom end of the pin 3 to complete the installation of the FPC cable. Then rotate the cover plate 2 clockwise to snap the boss 21 into the groove 16 on the side plate of the housing. At this time, the extension plate 44 of the positioning piece 4 is closely attached to the inner step surface of the cover plate 2 under the action of elastic force to complete the closing of the cover. The cover plate 2 achieves the double-stage positioning effect through the engagement of the boss 21 and the groove 16, and the close fit of the extension piece 44 and the inner step surface of the cover plate 2, making its structure stable and increasing the overall practicality.
