The utility model accomplishes the task in this way, a flexible cable with fatigue resistance and long service life, which comprises an input end, an output end and a connecting wire with two ends respectively connected with the input end and the output end, and is characterized in that: the center of the connecting lead consists of a plurality of wire cores, the outer parts of the wire cores are wrapped by multi-head fatigue-resistant spring tubes, and the outer parts of the multi-head fatigue-resistant spring tubes are wrapped by rubber layers.

In a specific embodiment of the utility model, the multi-head fatigue-resistant spring tube is formed by rolling a multi-head thin stainless steel wire in a single layer.

In another specific embodiment of the utility model, 3 to 24 heads of the multi-head fine stainless steel wire are adopted.

In yet another embodiment of the present utility model, the multi-headed fatigue resistant spring tube is of a left-hand or right-hand coiled construction.

In yet another embodiment of the present utility model, the multi-headed fatigue resistant spring tube is tight wound or gap wound.

In a further specific embodiment of the utility model, the outer part of the multi-head fatigue-resistant spring tube is coated with a rubber layer by adopting a plastic coating process.

In a further specific embodiment of the present utility model, the multi-headed fatigue resistant spring tube has a wall thickness of 0.03 to 0.6mm.

In a more specific embodiment of the utility model, the number of the wire cores in the multi-head fatigue-resistant spring tube is 1-24.

The utility model has the beneficial effects that due to the adoption of the structure, the utility model has the following advantages: the flexible cable provided by the utility model can be used in the use environments of frequent stress, frequent bending or twisting and the like, and the adopted multi-head fatigue-resistant spring tube is good in flexibility, strong in fatigue resistance and bending resistance, and can effectively protect the wire core, so that the service life of the flexible cable is prolonged, and the defects that the flexible cable in the existing market is easy to break, pull off and the like are effectively avoided; the second and the multi-head fatigue-resistant spring tubes are wrapped outside the wire cores due to the fact that the wall thickness of the second and the multi-head fatigue-resistant spring tubes is very thin, compared with similar products on the market, the size of the wire diameter is increased to be very small, the service life of the flexible cable is prolonged, and meanwhile the product structure is compact.
