For ordinary skilled in the art, the above-mentioned term can be understood according to the specific meaning in the utility model.

[0036] Please refer to Figures 1-6 As shown in FIG. 1, a flip FPC connector, comprising an insulating seat 10, a cover 20 and a fixed sheet 30, the fixed sheet 30 is provided with two, both sides of the insulating seat 10 are provided with fixed slots 11 corresponding to the two fixed sheets 30 respectively, the fixed sheet 30 is inserted in the corresponding fixed slot 11, the fixed sheet 30 has a welding plate 31 exposed outside the fixed slot 11, one side of the welding plate 31 is provided with a slot 32, the insulating seat 10 is provided with an FPC slot 12, a plurality of conductive terminals 40 are arranged in the FPC slot 12, one end of the cover 20 is provided with a rotating shaft 21 corresponding to the conductive terminal 40, the cover 20 is rotatably connected with the conductive terminal 40 through the rotating shaft 21, the rotating shaft 21 is formed with a plurality of extrusion blocks 22 distributed at intervals, the extrusion block 22 has an extrusion surface 23 protruding from the inner surface of the cover 20. In use, the connector is welded and connected with the solder pad on the PCB through the welding plate 31.

[0037] By setting the extrusion block 22 at the rotating shaft 21, and making the extrusion surface 23 of the extrusion block 22 protrude from the inner surface of the cover 20, so that only the FPC is extruded by the extrusion surface 23 in use, the requirement for the flatness of the extrusion surface 23 is reduced, the pressing effect is improved, the situation that the cover 20 rebounds due to low flatness is effectively improved, and the normal use of the connector is ensured.

[0038] Specifically, the conductive terminal 40 includes a terminal body 41 and a fixed foot 42, a conductive foot 43, and a soldering foot 44 integrally connected to the terminal body 41. The soldering foot 44 and the conductive foot 43 are located on the same side. The two side walls in the width direction of the FPC slot 12 are respectively provided with a first positioning groove 13 and a second positioning groove 14 corresponding to the conductive foot 43 and the fixed foot 42. The end of the fixed foot 42 forms a first limiting groove 45 corresponding to the rotating shaft 21. During assembly, the conductive terminal 40 is inserted into the FPC slot 12 from the rear end of the insulating base 10. The conductive foot 43 and the fixed foot 42 are respectively embedded in the corresponding first positioning groove 13 and second positioning groove 14. The soldering foot 44 is exposed at the rear end of the insulating base 10. The rotating shaft 21 is rotatably disposed in the first limiting groove 45 of the fixed foot 42.

[0039] In this invention, the rear end of the insulating base 10 is recessed with a first clearance step 15, and a return air channel is formed between the welding foot 44 and the first clearance step 15. By setting the first clearance step 15, the airflow of the welding foot 44 is better during welding, the heating is more uniform, and the welding flux residue due to poor air circulation is avoided, thus improving the welding quality. The width of the FPC slot 12 gradually decreases from front to back. This design increases the side wall thickness of the FPC slot 12, thereby increasing the overall strength of the insulating base 10 and making it more conducive to the clamping and fixing of the FPC.

[0040] In this invention, the conductive foot 43 has a first contact 46 and a second contact 47 spaced apart at one end near the first limiting groove 45, both of which are arc-shaped protrusions. The end of the pressure cover 20 away from the rotating shaft 21 is provided with an arc-shaped positioning protrusion 24, distributed on both sides of the pressure cover 20 along the axial direction of the rotating shaft 21. The insulating base 10 has third positioning grooves 16 on both sides along the length direction of the FPC slot 12, corresponding to the positioning protrusions 24. During use, the positioning protrusions 24 are engaged within the third positioning grooves 16, thereby better preventing the pressure cover 20 from rebounding.

[0041] The pressure cap 20 has a rotating shaft 21 at one end, and a protrusion 25 protrudes outward along the axial direction of the rotating shaft 21. The FPC slot 12 has a second limiting groove 17 corresponding to the protrusion 25. During assembly, the protrusion 25 is rotatably installed in the second limiting groove 17. When the pressure cap 20 is opened, the protrusion 25 abuts against the inner wall of the second limiting groove 17, and the rotating shaft 21 increases the distance between the fixing foot 42 and the conductive foot 43, thereby facilitating the insertion of the FPC. In this utility model, the front end of the insulating base 10 has a clearance notch 18 for partially exposing the pressure cap 20. By setting the clearance notch 18, the pressure cap 20 can be operated more conveniently.

[0042] In summary, this utility model, by setting an extrusion block at the rotating shaft and making the extrusion surface of the extrusion block protrude from the inner surface of the cover, allows the FPC to be extruded only by the extrusion surface during use. This reduces the requirements for the flatness of the extrusion surface, improves the pressing effect, effectively improves the situation of the cover rebounding due to low flatness, and ensures the normal use of the connector.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
