Description

Flat cable with adjustable inner diameter and outer diameter length difference Technical Field The present utility model relates to flat cables, and more particularly, to a flat cable with adjustable inner and outer diameter length differences. Background Flat cables are cables made of flat, flexible conductors bonded at high temperature with thin and flexible adhesive or paper films. The flat cable has the advantages of being capable of being bent and folded at will, thin in thickness, small in size, simple in connection, convenient to detach, easy to solve electromagnetic shielding (Electromagnetic Interference, EMI) and the like. Flat cables are typically formed with two flat cables for transmitting and receiving signals, respectively. However, when the flat cable is bent, the flat cable on the outer ring is stretched longer, and the flat cable on the inner ring is forced to compress and deform, which makes bending difficult or partially deforms to damage the cable. The above problems occur in general cables, but are more serious in flat cables. Disclosure of utility model The utility model aims to solve the problem of the existing flat cable and provides a flat cable with adjustable inner and outer diameter and length difference. In order to achieve the above and other objects, the present utility model provides a flat cable with adjustable inner and outer diameter length difference, comprising a flat cable body, an electronic wire assembly, and a spring structure, wherein the flat cable body comprises a flat insulating layer and a plurality of signal wires embedded in the insulating layer, the electronic wire assembly comprises a plurality of electronic wires, the length of the plurality of electronic wires is longer than that of the flat cable body, the electronic wire assembly spirally surrounds the flat cable body to form the spring structure, and two ends of the electronic wire assembly are respectively and electrically connected with two ends of the flat cable body. Optionally, the flat wire body has a first outer surface and a second outer surface opposite to each other, and two ends of the electron beam assembly are respectively electrically connected to the first outer surface. Alternatively, the electron beam assembly forming the spiral of the spring structure may be slid in the extending direction of the flat wire body. Optionally, the length of the electron beam assembly is longer than the length required to most closely encircle the flat wire body. Therefore, one flat cable is transformed into an electronic wire collection beam by the flat cable with adjustable inner and outer diameter length difference, and the electronic wire collection beam is wound on the other flat cable to form a spring-like mechanism. The electron beam collection beam forming the spiral can make up for the length difference in bending, so that the deformation effect caused by the inner diameter and outer diameter length difference in bending of the traditional double-layer flat cable is removed.
