Description

Technical Field

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

[0002] Flexible strip 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 strip and a circuit board. The flexible strip, also known as an FPC / FFC flexible strip or flexible circuit board, is used to insert into the connector. To improve the retention force after insertion and ensure the stability of the electrical connection, existing flexible strip connectors usually include a flip cover. This flip cover is used to press the flexible strip firmly, preventing it from easily detaching from the connector. However, in existing flexible strip connectors, the flexible strip 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 flexible strip, affecting the stability or reliability of the connection between the internal metal terminals and the flexible strip. Utility Model Content

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

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a flexible 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 has a bottom wall and a pair of side walls located at both ends of the bottom wall. The fixing member has a long strip-shaped insert arm inserted into the insulating body, a vertical crimping piece located at one end of the insert arm and bent inward, and a horizontal crimping piece. The horizontal crimping piece extends horizontally and covers the top of the flexible connector.

[0005] Furthermore, the transverse pressing piece and the vertical pressing piece are arranged adjacent to each other, the transverse pressing piece extends inward beyond the vertical pressing piece, and the front edge of the transverse pressing piece is also provided with an upward-curving guide edge.

[0006] Furthermore, the transverse pressing tab protrudes forward from the front edge of the flip cover, and at least a portion of the transverse pressing tab is located below the flip cover and between the flexible strip and 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 strip.

[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 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, a pair of latches are provided on both sides of the flexible strip, and the latches are engaged with the elastic buckle arm.

[0013] Compared with the prior art, this utility model optimizes the structure of the fastener by using the transverse pressing piece at its front end to resist the soft strip, preventing the soft strip from bending and deforming upwards and causing the flip cover to loosen, thus ensuring that the flip cover can be firmly pressed onto the soft strip, guaranteeing the reliability and stability of the connection function.

[0018] Please see Figures 1 to 4As shown, this utility model provides a flexible strip 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 crimp and contact a flexible strip 60 (such as a flexible printed circuit board FPC, FFC, etc.).

[0019] 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 strip 60.

[0020] 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 busbar 60. The ground terminals 22 have a top arm 24 that extends horizontally forward to 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.

[0021] 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 arm 47 extends downward at an angle and passes through the through hole 45 to press against the soft board 60 below the flip cover 40, providing grounding and clamping functions.

[0022] like Figure 4As shown, the fixing member 30 has a horizontally extending elongated insert arm 31, a vertical pressing piece 32 and a horizontal pressing piece 33 located at one end of the insert arm 31 and folded inward, 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 against the elastic buckle arm 46 of the metal liner 44, 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 buckle arm 46 inward, so that the elastic buckle arm 46 is locked into the slots 61 on both sides of the flexible strip 60, thereby preventing the flexible strip 60 from detaching. The transverse pressing piece 33 is located in front of the vertical pressing piece 32 and the two are arranged adjacent to each other. The transverse pressing piece 33 extends horizontally and covers the top of the flexible strip 60. Figure 3 As shown, preferably, the transverse pressing piece 33 extends inward beyond the vertical pressing piece 32, and the front edge of the transverse pressing piece 33 is also provided with an upwardly curved guide edge 330, which can guide the insertion of the soft board 60. The transverse pressing piece 33 is partially located below the flip cover 40, and partially protrudes forward from the front edge E of the flip cover 40.

[0023] The shielding cover 50 is disposed on the surface of the top wall 11 of the insulating body 10, such as Figure 2 As 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.

[0024] In summary, this utility model optimizes the structure of the fixing member 30 by adding an inwardly protruding transverse pressing piece 33 to the front end of the fixing member 30. The transverse pressing piece 33 abuts against the top of the flexible strip 60 to prevent the flexible strip 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 strip 60, guaranteeing the reliability and stability of the connection function.

[0025] 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.
