[0005] To achieve the above purpose, the utility model provides the following technical scheme: a retractable cable and wire, including a cable body and a middle rib. The cable body is wound around the outer wall of the middle rib. A limiting tube is sleeved outside the cable body and the middle rib. The cable body includes a plurality of conductor inner cores. A shielding layer is arranged on the outer walls of the plurality of conductor inner cores. A filling layer is arranged between the plurality of conductor inner cores and the shielding layer. A flame retardant layer is arranged on the outer wall of the shielding layer. A reinforcing layer is arranged on the outer wall of the flame retardant layer.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The cable body is wound around the outer wall of the middle rib. During normal use, the middle rib remains in a relaxed state. There is a large gap between the cable body and the middle rib, and the contact is not tight. When the cable needs to be stretched, the middle rib is pulled, and the middle rib stretches. At this time, the gap between the cable body on the outer wall of the middle rib and the middle rib adaptively shrinks, thereby realizing the telescopic function of the cable. It can not only stretch the length of the cable but also will not deform the cable body. At the same time, a limiting tube is sleeved outside the cable body and the middle rib. The cable body is limited by the limiting tube to avoid stacking or winding of the cable body. At the same time, the limiting tube is a telescopic flexible tube, which can stretch with the elongation of the middle rib and the cable body, making it convenient to use, enabling the cable to be stretched according to the required length, and being flexible to use;

[0013] The middle rib is made of a highly elastic and tough material, which is convenient for realizing the telescopic function. The flame retardant layer is made of cross-linked polyethylene flame retardant material, which has good flame retardant characteristics, improving the flame retardancy of the cable. The strengthening layer is made of butyl rubber, which improves the strength of the cable and extends the service life. A plurality of evenly distributed elastic ribs are arranged inside the strengthening layer. The elastic ribs are made of TPU material, which has the characteristics of high tension, high tensile force, toughness and aging resistance. At the same time, it has strong bending and torsion resistance. When the wire and cable are bent, it can quickly reset the wire and cable, thus avoiding winding of the wire and cable.
