[0021] Embodiment 1:

[0022] As attached Figure 1 The utility model is shown as a flexible flat cable, including a cable body 1, the cable body 1 includes a strip-shaped insulating layer and a plurality of parallel metal conductors placed in the insulating layer along the length direction, the metal conductor is a tinned flat copper wire, and both ends of the insulating layer have reinforced end portions 2, and the reinforced end portions 2 are provided with connecting buckles 3 connected to the metal conductors, so as to facilitate the flexible flat cable to be connected to other devices.

[0023] The insulating layer comprises a first surface 4 and a second surface opposite to each other. An elastic body 5 is formed on the first surface 4 along the length direction of the cable body 1 and protrudes from the surface of the insulating layer. Figure 2 As shown, two rows of elastomers 5 are respectively located on both sides of the first surface 4, making the cable body 1 more resilient. Under the obstruction of the elastomers 5, the insulating layer is difficult to bend to the limit, avoiding repeated bending and breakage. The two ends of the elastomer 5 are respectively connected to the reinforced end 2 to avoid cracking between the reinforced end 2 and the insulating layer, making the overall connection more secure. Evenly spaced holes 6 are formed on the elastomer 5, and the holes 6 are arranged along the width direction of the insulating layer, making the elastomer 5 lighter and more elastic, and better able to cope with deformation caused by bending. The hollow elastomer 5 can not only structurally but also visually remind the user not to bend excessively, further improving the anti-bending effect. In this embodiment, the holes 6 are square, and in other embodiments, the holes 6 can also be triangular or circular.

[0024] When installing some flexible flat cables, in order to avoid cable breakage, the cables are installed in a drag chain. The installation of the drag chain increases the installation steps and the use cost, and reduces the installation efficiency. This embodiment uses a simple structure to protect the flexible flat cable, and no additional structure is required, thereby improving the installation efficiency. The insulating layer and the elastic body 5 are integrally formed, which is more practical and convenient.

[0025] Embodiment 2:

[0026] The difference between this embodiment and the first embodiment is that the second surface also has an elastomer 5, and the elastomers 5 on the first surface 4 and the second surface are staggered, which can not only further improve the anti-bending performance, but also reduce the stacking space when the flexible flat cable is wound and stored, avoiding mutual obstruction of the elastomers 5 on different sides.

[0027] Embodiment 3:

[0028] As attached Figure 3 , Attachment Figure 4The flexible flat cable of this embodiment is shown. The difference between this embodiment and the first embodiment is that the hole 6 of this embodiment is semicircular, and the elastic body 5 forms a continuous arch. When the flexible flat cable is bent, the surfaces of the arched elastic body 5 are squeezed against each other, which effectively increases the bending radius of the flexible flat cable and avoids cracking of the insulation layer due to excessive bending. The joints of adjacent arches are connected by arc surfaces to avoid tearing during reverse bending and improve the use effect.

[0029] The utility model effectively increases the strength of the insulating layer of the flexible flat cable by setting the elastic body 5, avoids repeated bending and excessive bending of the flexible flat cable, has a simple structure, does not require cumbersome installation, has reliable performance, uses different elastic body 5 structures to adapt to various bending conditions, and has wide applicability.

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
