Abstract
The invention discloses a flexible cable for a vehicle. The flexible cable comprises a plurality of insulation wire cores, fillers, a wrapping layer, a protection sleeve layer and two reinforcing pieces arranged on the inner surface of the protection sleeve layer. The insulation wire cores are arranged around the fillers. The wrapping layer wraps the insulation wire cores. The protection sleeve layer is arranged on the outer surface of the wrapping layer, and the cross section of the protection sleeve layer is in a dovetail shape. The two reinforcing pieces are in central symmetry and are parallel to the insulation wire cores, and the reinforcing pieces are formed by stranding steel wire ropes. The reinforcing pieces replace a braided layer, so that production procedures are reduced, labor intensity is lowered, production cost is lowered, and production efficiency is improved. Meanwhile, the insulation wire cores are arranged around the fillers, due to the fact that the fillers are flexible, when the cable is bent, the fillers are compressed by the insulation wire cores, the outer edges of the fillers are deformed, therefore, the cable has bending durability and windability, and can be used in the repeated bending environment, and the service life of the cable is prolonged.

Summary of the invention
For the deficiency that prior art exists, the object of the invention is to provide a kind of flexible cable for vehicle that can use under the environment of alternating bending, reduces the requirement to production equipment simultaneously, improves production efficiency, and extend the useful life of cable.
To achieve these goals, the present invention realizes by the following technical solutions:
Flexible cable for vehicle of the present invention comprises many insulated wire cores, filler, lapping layer, restrictive coating and is arranged on two reinforcements of restrictive coating inner surface; Many insulated wire cores are arranged on around filler; Lapping layer is wrapped in the outside of many insulated wire cores; Restrictive coating is located at the outer surface of lapping layer, and the cross section of restrictive coating is swallow-tail form; Two reinforcements are in a center of symmetry and be parallel to each other with insulated wire cores, and reinforcement forms by seizing wire is stranded, and described lapping layer thickness is 0.5mm, and described reinforcement (5) diameter is 1.5mm.
