Description

Technical Field

[0001] This utility model relates to the field of FPC connectors, specifically to an FPC connector that is easy to install. Background Technology

[0002] FPC connectors, meaning "flexible printed connectors," are flexible circuit board or ribbon cable connectors primarily used in various civilian mobile communication devices and personal terminal devices. They enable signal connection or transmission between internal functional modules or with external devices, as well as connection between the device and power or signal sources, ultimately achieving power / signal connection. Driven by market demands for 3G mobile phones, smartphones, and ultra-thin laptops, the current development trend of FPC connectors is towards: low profile, ease of operation, multi-functionality, good electromagnetic compatibility, and standardized specifications.

[0003] Existing FPC connectors still have the following drawbacks: Traditional FPC connectors mostly use a "screw fastening" fixing method: In order to ensure a stable connection, the connector core must first be fixed to the reserved screw hole on the device motherboard with a screwdriver. In some ultra-thin devices, the screw hole diameter is only 1-2mm, and the screw is easy to slip when it is turned.

[0004] After fixing the core, the gold fingers of the FPC cable and the connector terminals need to be manually aligned. Tweezers and other tools are needed to press them into place, as manual operation can easily lead to deformation. Some models also require additional insulating tape for reinforcement. The entire process involves 3-5 independent steps, each requiring precise control of force, making it a high-barrier operation. The traditional FPC connector is highly tool-dependent and lacks a design for manual operation. It did not consider the development needs of "ease of operation," and the installation process relies on various specialized tools: the miniature screws (M1-M2 sizes) for fixing the core require a special precision screwdriver, which is incompatible with ordinary tools; the tiny clips require the assistance of pointed tweezers, as manual force is impossible; some connectors require a heat gun to heat and solder the terminals, further increasing the number of tools and steps, which does not meet the requirements of "convenient installation." Traditional connector fixing methods suffer from drawbacks such as "small contact area and dispersed fastening force": Screw-fixed types: Miniature screws rely solely on their threads to engage with the motherboard. Due to limitations in device height, the effective engagement length of the screw is often less than 1mm, and long-term use can easily lead to loosening of the threads due to vibration. When the device is subjected to external pressure (such as a mobile phone being dropped or a laptop being opened and closed), the screw can easily dislodge from its slot, causing the entire connector to shift. Therefore, existing FPC connectors still suffer from complex installation, inconvenience in installation, and a tendency to loosen after installation, requiring further improvement.

[0029] The following is combined with Figures 1-14 The present invention provides a detailed description of the easy-to-install FPC connector:

[0030] The easy-to-install FPC connector includes a core 1 and a plurality of conductive terminals 8 disposed inside the core 1. The conductive terminals 8 are evenly distributed inside the core 1. The front end of each conductive terminal 8 is a receiving end 3, and the rear end of each conductive terminal 8 is a limiting end 2. The front end of the core 1 is an insertion interface 6 for mating and insertion into the FPC. The core 1 is integrally formed by an upper cover 4 and a lower cover 5. The core 1 adopts an integral molding process, and the upper cover 4 and the lower cover 5 are formed by high-temperature injection molding. The connection between the upper cover 4 and the lower cover 5 is provided with mutually mating... The mortise and tenon structure has a terminal positioning groove 20 on the upper cover 4 for mating and installing conductive terminals 8. The conductive terminals 8 are inserted from the rear end of the upper cover 4 along the terminal positioning groove 20, so that the electrical terminal 3 of the conductive terminals 8 extends to the insertion interface 6. One end of the lower cover 5 extends outward to form two symmetrical pressing blocks 15. A pressing plate 17 is provided at the bottom of the pressing block 15. A fixing groove 16 is formed between the pressing block 15 and the pressing plate 17. A guide strip 18 is provided at one end of the pressing plate 17. The guide strip 18 extends along the height direction of the pressing plate 17.

[0031] The upper cover 4 has a slot 21 at one end near the limiting end 2, and the slot 21 penetrates the upper cover 4. The upper cover 4 extends outward from the end near the power terminal 3 to form an insertion part 23. The surface of the insertion part 23 is provided with a plurality of neatly arranged and non-contacting insertion slots 7. The upper cover 4 has a guide groove 10 at one end near the insertion part 23.

[0032] One end of the upper cover 4 extends outward to form a mounting part 9. The upper cover 4 is provided with a mounting groove 14 near the mounting part 9. The mounting groove 14 is provided with a fixing piece 11. The fixing piece 11 is bent into an L shape and is made of brass. The upper cover 4 is provided with a connecting groove 22 on the side near the mounting part 9.

[0033] One end of the upper cover 4 is recessed inward to form a contact portion 12, and one end of the lower cover 5 extends outward to form a limiting portion 19. The limiting portion 19 is engaged with the contact portion 12 to fix the upper cover 4 and the lower cover 5. The end of the upper cover 4 near the contact portion 12 is recessed inward to form a fastening portion 13.

[0034] In this embodiment, the slot 21 of the upper cover 4 facilitates the positioning and fixing of the conductive terminal 8, ensuring the stability of the conductive terminal 8 within the core 1 and preventing loosening due to vibration or external force, thereby improving the reliability and service life of the connector. The insertion portion 23 and insertion slot 7 of the upper cover 4 allow for precise insertion of the FPC and achieve a good electrical connection. The neat arrangement and non-contact design of the insertion slots 7 effectively prevents signal interference and improves the quality and stability of signal transmission. The guide slot 10 further guides the insertion of the FPC, ensuring smoothness and accuracy during the insertion process. The mounting portion 9 and mounting slot 14 of the upper cover 4, combined with the L-shaped bending structure of the fixing piece 11, provide additional mounting methods and fixing strength for the connector. The fixing piece 11 is made of brass, possessing good conductivity and mechanical strength, ensuring the stability of the connector after installation.

[0035] The easy-to-install FPC connector in this embodiment uses the cooperation of the pressing block 15, the pressing plate 17, and the guide strip 18 to fix the FPC connector by direct pressing, which simplifies the installation process, makes the FPC connector easy to install, and makes the connection more stable, preventing the FPC connector from becoming loose.

[0036] During installation, the conductive terminal 8 is inserted into the terminal positioning slot 20 of the upper cover 4 from the rear end, with the contact end 3 of the conductive terminal 8 extending to the insertion interface 6. The insertion force is checked by an automatic insertion machine to confirm proper placement. The gold fingers of the FPC are aligned with the insertion slot 7 and pushed horizontally along the guide groove 10 until the rear end of the FPC touches the guide strip 18 of the pressing plate 17. At this point, the contact end 3 of the conductive terminal 8 is in full contact with the gold fingers of the FPC. The pressing block 15 of the lower cover 5 is pressed down by hand. After the pressing plate 17 elastically deforms, it snaps into the slot of the external bracket. A "click" sound indicates that the fixing is complete. The L-shaped end of the fixing piece 11 is embedded in the slot, and the other end is soldered to the circuit board ground wire to complete grounding and reinforcement.
