Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a high-elasticity flexible flat cable, which includes a cable body 1, wherein an arched elastic portion 3 is disposed outside the cable body 1, so that the cable body 1 is arched at a position corresponding to the elastic portion 3; the elastic part 3 comprises an arch part 32, a first interface part 31 and a second interface part 33 are respectively arranged at two ends of the arch part 32, the end parts of the first interface part 31 and the second interface part 33 are in conical transition, the size of one end of the first interface part 31 and the second interface part 33, which faces away from the arch part 32, is smaller, the wall thickness of one end, which is close to the arch part 32, is consistent with that of the arch part 32, when the structure is adopted, namely the elastic force of the end parts of the first interface part 31 and the second interface part 33 is smaller, and the deformation elastic force of one end, which is close to the arch part 32, is larger, when the cable body 1 is bent, the first interface part 31 and the second interface part 33 are easily driven to deform, and the deformation is gradually reduced from the end parts of the first interface part 31 and the second interface part 33 to the end part of the arch part 32 and is uniform and excessive, so that the cable body 1 can be prevented from being bent to damage the core 2 due to the bending angle generated at the contact position with the elastic part 3.

The arch part 32, the first connecting port part 31 and the second connecting port part 33 are integrally formed, and the radian corresponding to the arch part 32 is not more than 60 degrees; the connecting parts of the arch part 32 and the first interface part 31 and the second interface part 33 are in arc transition, and the radian of the transition position is not less than 10 degrees; therefore, the transition of the elastic part 3 can be smoother, and the damage caused by overlarge bending angle of the wire core 2 can be avoided;

the wall thickness of the arch part 32 is 1/5-1/3 of the thickness of the cable body 1; generally 1/4 of the thickness of the cable body 1, so as to ensure stable support for the cable body 1, so that the cable body 1 can be in an arc shape at the position corresponding to the arch part 32; the length of the elastic part 3 is 5-15cm; the specific length can be selected according to the arrangement position of the cable body 1, and a plurality of elastic parts 3 can be arranged outside the cable body 1, and the arrangement principle is 1/m;

the elastic part 3 and the cable body 1 are integrally formed, when an integrally formed structure is adopted, the surfaces of the elastic part 3 and the cable body 1 are made of rubber materials, the connection stability between the elastic part and the cable body is better when the elastic part and the cable body are formed, and the position of the elastic part 3 is stable in the process that the cable body 1 is stretched or rebounded;
