[0012] The utility model provides a kind of connector flexible flat cable.Compared with prior art, it has the following beneficial effects:
[0013] The connector flexible flat cable significantly improves the manufacturing yield and durability of the product. Specifically, the ultrasonic manufacturing method is used instead of the original molding injection molding process. This change not only simplifies the production process, but also greatly improves the production efficiency. By dividing the molding and gluing part into two shells, precise assembly is achieved using ultrasonic waves, and the gap inside the ultrasonic wave is filled with waterproof environment-friendly silica gel, achieving seamless and tight connection. This innovative design not only solves the problems of molding and gluing defects, lack of glue, and large gap, but also significantly enhances the waterproof performance of the product, making it reach IP67 specifications, effectively preventing water and dust from entering. In addition, the newly manufactured flexible flat cable adopts a thinner double-layer structure design, dividing the internal connection line data into two pieces, and selecting a soft and tough material, so that the flexible flat cable can be folded without damaging the internal connection line. This improvement not only improves the flexibility and foldability of the flexible flat cable, but also significantly extends its service life. BRIEF DESCRIPTION OF DRAWINGS

[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0020] Please refer to Figures 1-4 The present application provides a technical solution: a connector flexible flat cable, mainly composed of a flexible flat cable body 1, a plurality of connectors 2 and a plurality of shell bodies 3 corresponding to the number of connectors 2, wherein,
[0021] The flexible flat cable body 1 is designed as a double-layer structure, specifically including an upper layer flat cable 11 and a lower layer flat cable 12. The two layers of flat cables form a double-layer flat cable structure at the overlapping part. Such design enhances the strength and conductivity of the region (reproduce the flexible flat cable, change the original thick single flat cable to a very thin double-layer flexible flat cable, divide the internal connecting line data into two pieces, and the material of the flat cable is soft and flexible, which can be folded excessively and is not easy to damage and break the internal connecting line). It is worth noting that the upper layer flat cable 11 and the lower layer flat cable 12 are each provided with a plurality of connector welding sites 13 in different sections. These welding sites are distributed in an alternating manner to optimize space utilization and current transmission efficiency;
[0022] The plurality of connectors 2 are accurately connected to the upper part of the connector welding sites 13 according to the design requirements, ensuring the stability and reliability of electrical connection. In order to further improve the overall protection performance, the flexible flat cable body 1 and the connectors 2 are jointly wrapped with a plurality of shell bodies 3. These shell bodies not only provide physical protection, but also effectively prevent external interference;
[0023] Outside the double-layer flat cable structure, we added a protective sleeve 14 made of silica gel. Due to its good flexibility and wear resistance, it can effectively resist external physical impact and chemical corrosion, prolonging the service life of the flexible flat cable;
[0024] The outer shell 3 is divided into two parts, the upper shell 31 and the lower shell 32. The upper shell 31 tightly wraps around the outside of the connector 2, providing direct protection to the connector. The lower shell 32 is located at the lower part of the flexible flat cable body 1, providing support and protection to the bottom of the entire flexible flat cable. The upper shell 31 and the lower shell 32 are fixed by ultrasonic welding technology. This connection method is not only firm and reliable, but also ensures the sealing of the outer shell, preventing water and dust from entering. In addition, the gap between the upper shell 31 and the lower shell 32 is filled with waterproof and environmentally friendly silicone. This silicone not only has good waterproof effect, but also ensures the sealing of the connection gap, effectively preventing water penetration from damaging the internal circuit. At the same time, the silicone material used is environmentally friendly and harmless, meeting the environmental performance requirements of modern electronic products. The upper part of the upper shell 31 is pre-drilled with holes. These holes allow the connector 2 to extend upwards through them, and the connecting end of the connector 2 is designed to be exposed outside the upper shell 31, making it easy to connect with external devices or circuit boards.
