Abstract
Description
Technical Field
[0001] This utility model relates to the field of FFC connector technology, and in particular to an FFC connector. Background Technology
[0002] FFC connectors are interconnect devices specifically designed for flexible flat cables (FFC) and play a crucial role in modern electronics manufacturing. Thanks to their unique design architecture and superior performance, they are widely used in many key industries.
[0003] In the crimping process of FFC connectors, operators must first accurately insert the FFC cable into the FFC connector, then close the crimp cap, and simultaneously apply pushing force to both sides of the cap to complete the locking action. However, given the small size of the FFC cable and the often compact space layout in its application scenarios, the actual operation is quite difficult. During the process of pushing the crimp cap, the FFC cable is prone to tilting or even detaching from the connector, resulting in poor connection and negatively impacting production efficiency.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0033] Please see Figures 1 to 11 The FFC connector according to one embodiment of the present invention includes an insulating base 10, a plurality of terminals 20 installed inside one side of the insulating base 10, grounding plates 30 installed inside opposite sides of the other side of the insulating base 10, and a pressure cap 40 hinged to the top of the insulating base 10. The insulating base 10 and the pressure cap 40 cooperate to clamp an FFC 50; one end of the FFC 50 has a mating connector 51, with gold fingers printed on opposite sides of the mating connector 51, and the FFC 50 has locking slots 52 on opposite sides corresponding to the mating connector 51.
[0034] The insulating base 10 is recessed inward on the side away from the terminal 20 to form an inner cavity 11. Side slots 12 are respectively provided on opposite sides of the insulating base 10 corresponding to the entrance of the inner cavity 11. The side slots 12 communicate with the inner cavity 11 and are used to accommodate the grounding piece 30. Specifically, when the grounding piece 30 is installed inside the side slot 12, the entrance of the inner cavity 11 is roughly closed in a "U" shape, which facilitates the insertion of the FFC50 into the inner cavity 11.
[0035] The top of the insulating base 10 is provided with a top opening 13, and the opposite sides of the pressure cover 40 pass through the top opening 13 and are hinged to the interior of the insulating base 10; wherein the pressure cover 40 is matched to cover the top opening 13.
[0036] The terminal 20 includes a substrate 21, a first abutment pin 22 and a second abutment pin 23 connected to one side of the substrate 21, and a solder pin 24 connected to the other side of the substrate 21; the first abutment pin 22 and the second abutment pin 23 are both used to contact the FFC50 after being embedded in the inner cavity 11; the substrate 21 and the solder pin 24 are located outside the insulating base 10.
[0037] Specifically, the first abutment pin 22 and the second abutment pin 23 are spaced apart. The first abutment pin 22 is connected to one end of the substrate 21, and the second abutment pin 23 is connected to the other end of the substrate 21. The first abutment pin 22 and the second abutment pin 23 are used to abut against the gold fingers on opposite sides of the connector 51 to achieve electrical connection between the terminal 20 and the FFC50.
[0038] The grounding plate 30 includes a grounding plate body 31, a limiting foot 32 connected to one end of the grounding plate body 31, a grounding spring foot 33 connected to the middle of the grounding plate body 31, and a contact piece 34 connected to the bottom of the grounding plate body 31. The grounding plate body 31 is embedded in the side slot 12. Both the limiting foot 32 and the grounding spring foot 33 extend into the inner cavity 11. The limiting foot 32 is located at the entrance of the inner cavity 11 and is used to guide the FFC 50 into the inner cavity 11. The grounding spring foot 33 is used to abut against the gold fingers of the connector 51; the contact piece 34 is located outside the insulating base 10.
[0039] The pressure cap 40 includes a cover plate 41, a pivot portion 42 connected to opposite sides of one end of the cover plate 41, and a locking foot 43 connected to opposite sides of the other end of the cover plate 41. The pivot portion 42 passes through the top opening 13 and is rotatably connected to the inside of the insulating base 10 to achieve a rotatable connection between the pressure cap 40 and the insulating base 10.
[0040] Specifically, the end of the cover plate 41 that is connected to the pivot 42 has a downwardly protruding wedge-shaped pushing part 44, which is used to abut against the FFC50. The inner side of the cover plate 41 is provided with a plurality of clearance grooves 410 evenly spaced, which are used to accommodate the first abutting foot 22, and the clearance grooves 410 also pass through the pushing part 44.
[0041] In this embodiment, the side of the locking foot 43 away from the rotating shaft 42 is provided with an inclined guide surface 45, which is used to abut against the FFC50.
[0042] During assembly, external force pushes the FFC50 to be inserted along the inlet of the inner cavity 11, and the connector 51 abuts against the guide surface 45 (e.g., Figure 7 As shown, since the guide surface 45 is a wedge-shaped surface, under the continuous insertion force of the FFC 50, the drive cap 40 is flipped and lifted along the rotating shaft 42, so that the cap 40 opens automatically, making room for further insertion of the FFC 50.
[0043] Subsequently, the connector 51 smoothly enters below the cover plate 41 until the connector 51 begins to abut against the pushing part 44 (e.g., Figure 9 (As shown by the dashed arrow), the external force continues to push the FFC50, driving the pressure cap 40 to flip in the opposite direction along the rotating shaft 42, causing the pressure cap 40 to close automatically. During the closing process of the pressure cap 40, the connector 51 and the pushing part 44 are interference-fitted, so that the FFC50 is firmly clamped between the pressure cap 40 and the insulating seat 10, achieving an automatic locking and clamping effect, as shown by the dashed arrow. Figure 11 As shown.
[0044] At this time, the interference fit between the connector 51 and the pusher 44 ensures that the FFC50 is securely clamped between the gland 40 and the insulating seat 10, achieving automatic locking and clamping. Figure 11 As shown. Simultaneously, the locking foot 43 passes between the limiting foot 32 and the grounding spring foot 33 and then engages with the locking slot 52, effectively preventing the FFC50 from retracting and detaching. Compared to traditional manual cap-closing operations, this invention guides the FFC50 into the cavity 11 through its inlet, and utilizes the synergistic effect of the guide surface 45 and the pushing part 44 to automatically open and close the cap 40, eliminating the need for manual operation, greatly reducing operational difficulty, ensuring connection effectiveness, and improving production efficiency.
[0045] The aforementioned FFC connector has a simple structure and is easy to use. It does not require manual operation of the opening and closing of the pressure cover 40. Through the guidance of the inlet of the inner cavity 11 and the synergistic action of the guide surface 45 and the push part 44, the FFC50 can be installed quickly and accurately, which greatly reduces the difficulty of operation, ensures the connection effect, and significantly improves production efficiency.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
