Description

Technical Field

[0001] This utility model relates to the field of ribbon cable technology, specifically a flexible flat ribbon cable with high tensile strength. Background Technology

[0002] In the utility model patent application CN215988141U, published on March 8, 2022, entitled "A Flexible Flat Cable", this utility model discloses a flexible flat cable, belonging to the technical field of flexible flat cable. The key technical point is that the flexible flat cable includes a main body with conductors at both ends. A protective sleeve is provided on the main body, with a reinforcing layer inside the protective sleeve, an insulating sleeve inside the reinforcing layer, an elastic layer inside the insulating sleeve, a flame-retardant sleeve inside the elastic layer, and a shielding sleeve inside the flame-retardant sleeve. The shielding sleeve wraps around the main body, and a cut-resistant layer is provided on the outside of the protective sleeve. The cut-resistant layer includes a polyethylene fiber layer and an elastic rubber layer. The polyethylene fiber layer is bonded to the outside of the elastic rubber layer, and an anti-wear layer is provided on the outside of the polyethylene fiber layer. This solves the problem that flexible flat cables are easily scratched by external objects during use, and that the protective strength of flexible flat cables is low.

[0003] In the aforementioned patents or prior art, the flexible flat cable (FFC) may be frequently moved and bent during use, especially in dynamic applications such as robot joints and foldable screen devices. This can cause tensile stress on the cable, and the FFC may be accidentally pulled during installation or maintenance, resulting in the cable plug separating from the socket. Utility Model Content

[0004] The purpose of this invention is to provide a flexible flat cable with high tensile strength to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible flat ribbon cable with high tensile strength, comprising a ribbon cable body, a plug at one end of the ribbon cable body, a socket for which a matching plug is inserted, a protective component on the outer surface of the ribbon cable body, the protective component comprising a protective shell for protecting the ribbon cable body, the protective shell being formed by two shells being snapped together, and through holes being opened at both ends of the protective shell, the ribbon cable body passing through one of the through holes, being wound by an internal winding mechanism and then passing out through the other through hole, the plug and socket being provided with matching snap-fit ​​mechanisms.

[0006] Furthermore, the winding mechanism includes a fixed shell fixedly disposed within the protective shell. Two sets of winding rods are slidably disposed within the fixed shell, and the winding rods are L-shaped, each consisting of a horizontal bar and a vertical bar. One horizontal bar of the winding rod is at the bottom, and the other horizontal bar is at the top. A telescopic rod is provided between the two winding rods. A limiting component is provided between the fixed shell and the two sets of winding rods. The two sets of winding rods are slidably connected to the protective shell through a sliding component. Two sets of winding rollers are symmetrically disposed on the inner wall of the protective shell, and the two sets of winding rollers are respectively located below the two sets of winding rods.

[0007] Furthermore, the limiting component includes sliding strips symmetrically opened at the upper and lower ends of the inner wall of the fixed shell, and the part of the winding rod where the crossbar is located is provided with a limiting groove that cooperates with the sliding strip.

[0008] Furthermore, the sliding assembly includes sliders disposed at both ends of the two sets of winding rods, and the inner wall of the protective shell is provided with a groove that cooperates with the sliders.

[0009] Furthermore, the snap-fit ​​mechanism includes first fixing blocks fixed at both ends of the plug, two sets of first fixing blocks having insertion holes, second fixing plates fixed at both ends of the socket, two sets of second fixing plates having mounting grooves, hooks that cooperate with the insertion holes being slidably provided in the mounting grooves, and reset components that drive the hooks to reset being provided in the mounting grooves.

[0010] Furthermore, the reset component includes a spring disposed in the mounting groove, one end of the spring being connected to the inner wall of the mounting groove, and the other end being connected to a hook.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this flexible flat cable with high tensile strength is reasonable and has the following advantages: (1) This flexible flat cable significantly improves tensile strength and connection stability through innovative protective components and winding mechanism design. When the cable body is pulled by external force, the winding rod and telescopic rod inside the protective shell form a dynamic buffer system: two sets of L-shaped winding rods achieve synchronous contraction through the sliding connection of the slider and the groove. Combined with the elastic deformation of the telescopic rod, it can effectively absorb and disperse the tensile energy. For example, when the cable is subjected to longitudinal tension, the horizontal bar of the winding rod moves along the sliding bar limit groove, and the vertical bar drives the cable body to form a detour path, so that the tension is decomposed into multiple buffer forces, avoiding direct damage to the cable body by concentrated stress. The symmetrical distribution of the winding rollers The design further optimizes the force distribution, ensuring that the ribbon cable winds evenly rather than twists locally when under stress. This reduces the risk of metal fatigue fracture caused by repeated bending. The design also allows the ribbon cable to automatically adjust its winding state to a certain extent, facilitating subsequent storage and organization. By winding neatly onto the winding rod and winding roller, the messiness of the ribbon cable can be reduced, and it also helps protect the ribbon cable from damage during storage. This design improves the durability and reliability of the ribbon cable. Under the same tensile conditions, the connection stability of the ribbon cable using this design is several times higher than that of the traditional structure, making it particularly suitable for applications requiring high mechanical strength and stability. (2) The plug and socket design of this flexible flat ribbon cable significantly enhances the stability and safety of the connection through the snap-fit ​​mechanism. This design ensures that the plug can be firmly fixed when inserted into the socket, preventing it from falling off due to vibration or pulling. When the plug is inserted into the socket, the snap hook slides upward and inserts into the socket under the squeezing action of the socket. After insertion, the snap hook resets and completes the fixation under the action of the spring. This setting prevents the plug and socket from falling off under the action of external pulling force, making the connection between the plug and socket more stable. In addition, the design of this snap-fit ​​mechanism can also improve the safety of use. In applications that require frequent plugging and unplugging or are used in harsh environments, it can prevent electrical faults or safety accidents caused by unstable connection. By ensuring a reliable connection between the plug and socket, maintenance costs and potential safety hazards are reduced. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 The present invention provides a technical solution as follows: Example 1: A flexible flat ribbon cable with high tensile strength includes a ribbon cable body 100. The ribbon cable body 100 has a plug 101 at one end, and a socket 102 that mates with the plug 101 is inserted into the plug 101. The outer surface of the ribbon cable body 100 is provided with a protective component. The protective component includes a protective shell 200 for protecting the ribbon cable body 100. The protective shell 200 is composed of two shells that are snapped together. Both ends of the protective shell 200 have through holes 201. The ribbon cable body 100 passes through one of the through holes 201, is wound by an internal winding mechanism, and then passes through the other through hole 201. The plug 101 and the socket 102 are provided with a matching snap-fit ​​mechanism.

[0016] The winding mechanism includes a fixed shell 202 fixedly disposed within a protective shell 200. Two sets of winding rods 204 are slidably disposed within the fixed shell 202. The winding rods 204 are L-shaped and are composed of horizontal and vertical rods respectively. One horizontal rod of the winding rods 204 is at the bottom and the other horizontal rod is at the top. A telescopic rod 208 is provided between the two winding rods 204. A limiting component is provided between the fixed shell 202 and the two sets of winding rods 204. The two sets of winding rods 204 are slidably connected to the protective shell 200 through a sliding component. Two sets of winding rollers 209 are symmetrically disposed on the inner wall of the protective shell 200, and the two sets of winding rollers 209 are respectively located below the two sets of winding rods 204.

[0017] The limiting component includes sliding bars 203 symmetrically opened at the upper and lower ends of the inner wall of the fixed shell 202, and the winding rod 204 has a limiting groove 205 in the part where the crossbar is located, which cooperates with the sliding bars 203.

[0018] The sliding assembly includes sliders 206 disposed at both ends of the two sets of winding rods 204, and the inner wall of the protective shell 200 is provided with a groove 207 that cooperates with the sliders 206.

[0019] The latching mechanism includes first fixing blocks 300 fixed at both ends of the plug 101, and two sets of first fixing blocks 300 are provided with socket holes 301. The socket 102 is fixed at both ends with second fixing plates 302, and two sets of second fixing plates 302 are provided with mounting grooves 303. Hooks 305 that cooperate with the socket holes 301 are slidably provided in the mounting grooves 303. A reset member that drives the hooks 305 to reset is provided in the mounting grooves 303.

[0020] The reset component includes a spring 304 disposed in the mounting groove 303, one end of the spring 304 being connected to the inner wall of the mounting groove 303, and the other end being connected to a hook 305.

[0021] Working principle: In use, the protective shell 200 consists of two snap-fit ​​shells for easy installation. The protective shell 200 protects the ribbon cable body 100 from damage caused by external factors such as dust, moisture, and impact. The end of the ribbon cable body 100 away from the plug 101 passes through the through hole 201 and sequentially through one winding roller 209, one winding rod 204, and another winding rod 204, finally winding onto another winding roller 209 and exiting through another through hole 201. Figure 7As shown, one end of the ribbon cable body 100 connects to other devices via a plug 101 and a socket 102. Excessive tension may cause the plug 101 to loosen or even detach from the socket 102. When the ribbon cable body 100 is subjected to tension, the two winding rods 204 retract under the action of the slider 206, the groove 207, and the telescopic rod 208, which can alleviate the direct impact of tension on the ribbon cable body 100. The retraction of the winding rods 204 can distribute and buffer the tension, reduce the risk of damage to the ribbon cable body 100, and extend the service life of the ribbon cable. Furthermore, the retraction of the winding rods 204 can reduce the impact of tension on the connection between the plug 101 and the socket 102, which helps maintain the stability of the connection, ensures the normal transmission of signals and power between devices, and avoids problems such as malfunctions or data loss due to unstable connections. In addition, the ribbon cable body 100 automatically adjusts its winding state to a certain extent, which is convenient for subsequent storage and organization. The cable is neatly wound around the winding rod 204 and the winding roller 209, reducing the messiness of the cable body 100 and helping to protect the cable body 100 from damage during storage. When the plug 101 is inserted into the socket 102, the first fixing block 300 and the second fixing plate 302 are aligned. The hook 305 is initially misaligned with the socket 301. During the insertion of the plug 101 into the socket 102, the socket 301 will squeeze the hook 305, and the hook 305 will slide upward in the mounting groove 303. At this time, the hook 305 is inserted into the socket 301. After insertion, the hook 305 is pushed back to its original position by the spring 304, completing the fixation. This setting prevents the plug 101 from falling off the socket 102 under external pulling force. This setting makes the connection between the plug 101 and the socket 102 more stable and prevents them from falling off due to vibration or pulling, thereby improving the safety of use.
