Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more particularly to a flexible circuit board connector. Background Technology

[0002] Flexible printed circuit board (FPC) connectors are a common type of small electrical connector used in consumer electronics products such as computers and mobile phones. They are used to establish an electrical connection between a flexible printed circuit board (FPC) and a circuit board. The FPC is often abbreviated as FPC / FFC, and can also be called a flexible circuit board, flexible wiring board, or flexible busbar. It is used to insert into the FPC connector. To improve the retention force after the FPC is inserted and ensure the stability of the electrical connection, existing FPC connectors usually include a flip cover. This flip cover is used to press the FPC firmly against the connector, preventing it from easily detaching. However, in existing FPC connectors, the FPC often bends and deforms upwards under external forces, causing the flip cover to arch upwards or become loose. This prevents the flip cover from firmly pressing the FPC against the FPC, affecting the stability or reliability of the connection between the internal metal terminals and the FPC. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a flexible board connector to improve the problem of loose flip cover caused by flexible board deformation in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a flexible board connector, comprising an insulating body, terminals housed within the insulating body, a flip cover assembled on the insulating body, and a pair of fixing members fixed at both ends of the insulating body. The insulating body is provided with a bottom wall and a pair of side walls located at both ends of the bottom wall. A receiving space for accommodating a flexible board is formed between the bottom wall and the pair of side walls. The fixing member is provided with an inwardly extending vertical stop plate. The vertical stop plate is vertically arranged and has a long strip-shaped bottom edge facing the surface of the flexible board.

[0005] Furthermore, the vertical stop plate includes an obliquely extending section and a bent section formed by bending forward from the end of the obliquely extending section. The bent section extends in the front-back direction, and the extension length of the bent section is less than the extension length of the obliquely extending section.

[0006] Furthermore, the vertical stop plate also has an outwardly folded top edge, which is distributed on the bent section and at least part of the oblique extension section, and a portion of the vertical stop plate protrudes forward from the front edge of the flip cover.

[0007] Furthermore, the flip cover has a longitudinally elongated main cover plate and a metal liner embedded in the main cover plate. The longitudinal ends of the metal liner plate are bent and extended to form a pair of U-shaped elastic buckle arms, which interfere with the fastener.

[0008] Furthermore, the metal liner is also provided with a pair of downwardly bent and extended spring arms, which extend downwardly through the main cover plate and press against the flexible plate.

[0009] Furthermore, the terminal includes a row of signal terminals and a row of ground terminals arranged in a front-to-back pattern. The signal terminals are inserted into the bottom wall from front to back, while the ground terminals are inserted into the insulating body from back to front.

[0010] Furthermore, the flexible board connector also includes a shielding cover covering the insulating body. The shielding cover has an elongated upper cover, a pair of fixing flaps extending downward from both longitudinal ends of the upper cover, and a rear cover extending downward from the rear edge of the upper cover.

[0011] Furthermore, a pair of slots are provided on the side wall of the insulating body, the pair of slots extending from top to bottom into the interior of the side wall and penetrating downward through the insulating body to accommodate the pair of fixing tabs.

[0012] Furthermore, the flexible plate has a pair of latches on both sides, which engage with the elastic buckle arm.

[0013] Furthermore, the fastener also has a horizontally extending elongated insert arm and a vertical pressing piece formed by folding one end of the insert arm inward. The vertical stop piece is integrally connected with the vertical pressing piece, and the vertical pressing piece extends downward beyond the elongated bottom edge of the vertical stop piece.

[0014] Compared with the prior art, this utility model optimizes the structure of the fastener by using the vertical stop plate at its front end to resist the flexible plate, preventing the flexible plate from bending and deforming upwards and causing the flip cover to loosen, thus ensuring that the flip cover can be firmly pressed onto the flexible plate and guaranteeing the reliability and stability of the connection function.

[0019] Please see Figures 1 to 4As shown, this utility model provides a flexible circuit board connector 100, including: an elongated insulating body 10, a plurality of terminals 20 housed within the insulating body 10, a pair of fixing members 30 fixed at both ends of the insulating body 10, a flip cover 40 assembled on the insulating body 10, and a shielding cover 50 covering the insulating body 10. The insulating body 10 is used to support the terminals 20, fixing members 30 and shielding cover 50, while the fixing members 30 are used to weld and fix the insulating body 10 to a circuit board (not shown), and the terminals 20 are used to press-fit into a flexible circuit board 60 (such as a flexible printed circuit board FPC, FFC, etc.).

[0020] like Figure 2 As shown, the insulating body 10 includes a top wall 11, a bottom wall 12 and a pair of side walls 13. The top wall 11 and the bottom wall 12 are longitudinally elongated, and their longitudinal ends are integrally connected to the pair of side walls 13. The top wall 11 is located behind the bottom wall 12 and is higher than the bottom wall 12, thus protruding from the bottom wall 12. The upper surface of the top wall 11 is flush with the upper surface of the pair of side walls 13. The bottom wall 12 is provided with a plurality of equally spaced channels 121 for accommodating the plurality of terminals 20; the pair of side walls 13 extend forward integrally from both longitudinal ends of the top wall 11, and the inner side of the side wall 13 is provided with a slot 17 for accommodating the fixing member 30. Preferably, each side wall 13 is provided with a slot 131, the slot 131 extends from top to bottom into the interior of the side wall 13 and penetrates downward through the insulating body 10 so that the shielding cover 50 can pass through to achieve soldering and fixing with the circuit board. Preferably, the slot 131 is located at both longitudinal ends of the top wall 11, so that the shielding cover 50 is combined and fixed to the top wall 11 and the side wall 13 by means of the slot 131, so as to achieve reliable connection and fixing with the insulating body 10. The bottom wall 12 is located between the pair of side walls 13, and the bottom wall 12 is provided with a plurality of terminal slots 121 for accommodating the terminals 20. The bottom wall 12, the top wall 11 and the pair of side walls 13 form an accommodating space for accommodating the flexible board 60.

[0021] like Figure 2As shown, the terminal 20 includes a row of signal terminals 21 and a row of ground terminals 22 distributed front to back. The signal terminals 21 are inserted into the groove 121 of the bottom wall 12 from front to back, while the ground terminals 22 are inserted into the insulating body 10 from back to front. The signal terminals 21 and ground terminals 22 are distributed front to back. Specifically, the signal terminals 21 are fixed to the bottom wall 12 and have contact arms 23 that protrude upward from the bottom wall 12 for electrical contact with the flexible board 60. The ground terminals 22 have a top arm 24 that extends horizontally forward above the signal terminals 21 and a welding arm 25 that extends horizontally backward out of the insulating body 10. The top arm 24 is used to pivotally engage with the flip cover 40, and the welding arm 25 is used to weld to the circuit board.

[0022] like Figure 2 As shown, the flip cover 40 has a longitudinally elongated main cover plate 41 and mounting portions 42 protruding outward from both longitudinal ends of the main cover plate 41. The inner edge of the main cover plate 41 forms several slots 43 and a pivot shaft (not shown) located within the slots 43. The slots 43 are used to accommodate the top arm 24 of the grounding terminal 22, and the pivot shaft (not shown) pivotally engages with the top arm 24. Preferably, the main cover plate 41 also has a pair of through holes 45, which penetrate the main cover plate 41 vertically. In a preferred embodiment of this utility model, the flip cover 40 further includes a metal liner 44, which is embedded in the main cover plate 41 by injection molding. The longitudinal ends of the metal liner 44 are bent to extend into a pair of U-shaped elastic latching arms 46, which are exposed at both longitudinal ends of the main cover plate 41 and are used for interference engagement with the fixing member 30. Preferably, the metal liner 44 is further provided with a pair of downwardly bent and extended spring arms 47 (see...). Figure 3 The spring-loaded arm 47 extends downward at an angle and passes through the through hole 45 to press against the flexible plate 60 below the flip cover 40, providing grounding and clamping functions.

[0023] like Figure 4As shown, the fixing member 30 has a horizontally extending elongated insert arm 31, a vertical pressing piece 32 located at one end of the insert arm 31 and folded inward, a vertical stop piece 33 extending obliquely inward from the vertical pressing piece 32, and an outwardly bent mounting arm 34. The insert arm 31 is inserted into the side wall 13 of the insulating body 10 from front to back and fixed in the slot 17, and the bottom edge of the insert arm 31 has barbs 310. The vertical pressing piece 32 extends downward and is used to abut inward against the elastic latching arm 46 of the metal backing plate 44 to press the flip cover 40, so that the flip cover 40 is not easy to loosen in the closed state. At the same time, the vertical pressing piece 32 also squeezes the elastic latching arm 46 inward, so that the elastic latching arm 46 is engaged in the latching slots 61 on both sides of the flexible plate 60, thereby preventing the flexible plate 60 from detaching. The vertical stop plate 33 is integrally connected to the vertical pressing plate 32, and the vertical stop plate 33 is vertically arranged or perpendicular to the surface of the flexible plate 60. It has an elongated bottom edge 330 facing the flexible plate 60 and an outwardly folded top edge 331. The top edge 331 is located above the bottom edge 330 and can guide the insertion of the flexible plate 60. Preferably, the vertical stop plate 33 includes an obliquely extending section 332 and a bent section 333 formed by bending forward from the end of the obliquely extending section 332. The obliquely extending section 332 extends inward from the vertical pressing plate 32, and the bent section 333 extends in the front-back direction. The extension length of the bent section is less than the extension length of the obliquely extending section 332. The top edge 331 is distributed on the bent section 333 and at least part of the obliquely extending section 332. Preferably, the vertical pressing piece 32 extends downward beyond the elongated bottom edge 330 of the vertical stop piece 33.

[0024] The oblique extension 332 and the bent section 333 of the vertical stop plate 33 both cover the top of the flexible plate 60, such as Figure 3 As shown, preferably, the vertical stop 33 extends inward beyond the vertical pressing piece 32, and a portion of the vertical stop 33 protrudes forward from the front edge E of the flip cover 40.

[0025] The shielding cover 50 is disposed on the surface of the top wall 11 of the insulating body 10, such as Figure 2As shown, the shielding cover 50 is integrally stamped from metal material. It has an elongated upper cover 51, a pair of fixing flaps 52 extending downward from both longitudinal ends of the upper cover 51, and a rear cover 53 extending downward from the rear edge of the upper cover 51. The upper cover 51 covers the surface of the top wall 11. The fixing flaps 52 are inserted downward into the slot 131 to fix them to the insulating body 10. The rear cover 53 covers the rear side of the insulating body 10. The upper cover 51 and the rear cover 53 respectively cover the outside of the grounding terminal 22, which can effectively shield interference signals.

[0026] In summary, this utility model optimizes the structure of the fixing member 30 by adding an inwardly protruding vertical stop 33 to the front end of the fixing member 30. The vertical stop 33 abuts against the top of the flexible plate 60 to prevent the flexible plate 60 from bending and deforming upward and causing the flip cover 40 to loosen. This ensures that the flip cover 40 can be firmly pressed onto the flexible plate 60, thus guaranteeing the reliability and stability of the connection function.

[0027] The above description is merely the preferred embodiment of this utility model and is not intended to limit this utility model in any way. Any possible variations and modifications made by those skilled in the art to the technical solution of this utility model without departing from the scope of the technical solution of this utility model using the methods disclosed above shall fall within the scope of protection of the claims.
