Description

Technical Field

[0001] This utility model relates to the field of flat FFC, specifically to a flat FFC structure. Background Technology

[0002] Flat FFC is a flat, flexible cable made of multiple layers of insulating film and flat conductor through a lamination technique. It features thinness, high flexibility, and high-density wiring.

[0003] Traditional flat FFCs lack certain protective measures in their structure, such as weak anti-infection capabilities, making them susceptible to electromagnetic interference, with poor waterproof performance, making them prone to moisture, and insufficient wear resistance. Long-term wear leads to external wear and increased contact resistance.

[0004] Therefore, it is necessary to invent a flat FFC structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flat FFC structure. The flat cable body is covered with a shielding layer made of aluminum foil, which effectively enhances protection against electromagnetic interference and radio frequency interference. A flame-retardant layer made of halogenated material is then applied to the outside of the shielding layer to improve flame retardancy and reduce fire risk. A buffer layer made of silicone absorbs impact and protects the internal conductors and structure. A reinforcing layer made of aramid fiber increases the strength of the FFC and prevents stretching or tearing. A waterproof layer made of fluororubber prevents moisture penetration and protects the internal conductors. A wear-resistant layer made of polyurethane enhances the wear resistance of the FFC surface and extends its service life. This addresses the problems of traditional flat FFC structures lacking protective measures, such as weak anti-infection capabilities, making them susceptible to electromagnetic interference, having poor waterproof performance, being prone to moisture, and exhibiting insufficient wear resistance, leading to external wear and increased contact resistance over time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flat FFC structure, including a flat cable body for signal transmission;

[0007] A protective layer is fitted over the flat cable body to protect it. The protective layer includes an adhesive layer that is adhered to the top and bottom sides of the flat cable body. A shielding layer is adhered to the outside of the adhesive layer. A flame-retardant layer is covered to the outside of the shielding layer. A buffer layer is covered to the outside of the flame-retardant layer. A reinforcing layer is covered to the outside of the buffer layer. A waterproof layer is covered to the outside of the reinforcing layer. A wear-resistant layer is covered to the outside of the waterproof layer.

[0008] FFC connectors are crimped onto both sides of a flat cable body for connection.

[0009] Preferably, the flat cable body is provided with two layers, and an insulating interlayer is provided between the two flat cable bodies.

[0010] Preferably, the shielding layer is made of aluminum foil, and the flame-retardant layer is made of halogen-containing material.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention protects the entire flat FFC (Flat Cable Containing Capacitor) by using a flat cable body and a protective layer. The flat cable body is covered with a shielding layer made of aluminum foil, which effectively enhances protection against electromagnetic interference and radio frequency interference.

[0025] The protective layer 3 is sleeved on the outside of the flat cable body 1 to protect the flat cable body 1. The protective layer 3 includes an adhesive layer 301, which is attached to the upper and lower sides of the flat cable body 1. A shielding layer 302 is attached to the outside of the adhesive layer 301. A flame-retardant layer 303 is covered to the outside of the shielding layer 302. A buffer layer 304 is covered to the outside of the flame-retardant layer 303. A reinforcing layer 305 is covered to the outside of the buffer layer 304. A waterproof layer 306 is covered to the outside of the reinforcing layer 305. A wear-resistant layer 307 is covered to the outside of the waterproof layer 306.

[0026] The FFC connector 4 is crimped onto both sides of the flat cable body 1 for connection. The flat cable body 1 is covered by a shielding layer 302, which is made of aluminum foil and effectively enhances protection against electromagnetic interference and radio frequency interference. The shielding layer 302 is covered by a flame-retardant layer 303, which is made of halogenated material to improve flame retardancy and reduce fire risk. The buffer layer 304 is made of silicone to absorb impact and protect the internal conductor and structure. The reinforcing layer 305 is made of aramid fiber to improve the strength of the FFC and prevent stretching or tearing. The waterproof layer 306 is made of fluororubber to prevent moisture penetration and protect the internal conductor. The wear-resistant layer 307 is made of polyurethane to enhance the wear resistance of the FFC surface and extend its service life.

[0027] like Figure 1 and Figure 2 As shown, the flat cable body 1 is provided with two layers, and an insulating interlayer 2 is provided between the two flat cable bodies 1. When one of the flat cable bodies 1 fails due to short circuit or mechanical damage, the other flat cable body 1 can still continue to work, thereby improving the reliability and maintenance efficiency of the system.

[0028] like Figure 1 and Figure 3As shown, the shielding layer 302 is made of aluminum foil, and the flame retardant layer 303 is made of halogen-containing material. The shielding layer 302 can effectively enhance the protection against electromagnetic interference and radio frequency interference, while covering the flame retardant layer 303 improves flame retardancy and reduces the risk of fire.

[0029] like Figure 3 As shown, the buffer layer 304 is made of silicone, and the reinforcing layer 305 is made of aramid fiber.

[0031] like Figure 1 and Figure 4 As shown, the FFC connector 4 has an internal mounting groove 5, and a spring piece 6 is fixedly connected inside the mounting groove 5. When the flat cable body 1 is inserted into the mounting groove 5 inside the FFC connector 4, the spring piece 6 is used to press and strengthen the connection between the flat cable body 1 and the FFC connector 4.

[0032] The working principle of this utility model is as follows: First, the flat cable body 1 is bonded to the outside of the protective layer 3 using the adhesive layer 301. Next, both ends of the flat cable body 1 are inserted into the mounting slots 5 inside the FFC connector 4. The spring clips 6 inside the mounting slots 5 are used to press the cable together, strengthening the connection between the flat cable body 1 and the FFC connector 4. Finally, the flat cable body 1 and the inner conductors of the FFC connector 4 are soldered or precision-pressed. Then, the FFC connectors 4 at both ends are inserted into electronic devices for signal transmission. During normal operation, the flat cable body 1 is covered by a shielding layer 302. Material 302 is made of aluminum foil, which can effectively enhance the protection against electromagnetic interference and radio frequency interference. The outer layer of shielding layer 302 is covered with flame retardant layer 303, which is made of halogen-containing material to improve flame retardancy and reduce fire risk. The buffer layer 304 is made of silicone to absorb impact and protect the internal conductors and structure. The reinforcing layer 305 is made of aramid fiber to improve the strength of FFC and prevent stretching or tearing.
