Technical Field

The utility model belongs to the technical field of the cable, especially, relate to a spiral cable for electromagnet.

Background

The electromagnetic chuck is an electromagnetic clamp, and utilizes the electromagnetic principle, generates magnetic force by electrifying an internal coil thereof, tightly attracts a workpiece contacted on the surface of a panel through a magnetic conduction panel, and eliminates the magnetic force to realize demagnetization by powering off the internal coil thereof, thereby putting down the workpiece. At present, the cable that is used for hoist electromechanical magnetic chuck among the prior art is the sharp cable, and the coiling and uncoiling of cable mainly realizes through the reel, and the reel is installed on hoist girder travelling car, because at the in-process of coiling and uncoiling the cable, the cable is in taut state always, very easy fatigue damage, and life cycle is short, and the winding phenomenon in disorder appears easily, inconvenient use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a spiral cable for electromagnetic chuck for solve the easy fatigue damage of cable that is used for electromagnetic chuck among the prior art, technical problem of inconvenient use.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a spiral cable for electromagnetic chuck, including being the cable body that the spiral was convoluteed, the cable body includes a plurality of sinle silk unit, and the outside cladding of sinle silk unit has the outer jacket, is provided with in the space between outer jacket and the sinle silk unit and supports the packing element, supports the inner wall of packing element and outer jacket and laminates mutually.

Preferably, the quantity of sinle silk unit is two, and two sinle silk units are tangent to be set up inside outer sheath, and the quantity that supports the filling unit is two, supports the filling unit symmetry and sets up in the both sides of two sinle silk units and tangent with the sinle silk unit.

Preferably, the core unit comprises a core conductor, a core insulating layer is extruded outside the core conductor, and the two core insulating layers are tangent to each other.

Preferably, the core conductor is a five or six type conductor and the core insulation layer is a TPV elastomer layer.

Preferably, the supporting filler unit is an elastomer filler strip.

Preferably, the outer jacket is a TPU elastomer layer.

The utility model has the advantages that: the cable has a simple structure, the cable body is arranged to be spiral, so that the cable body has good tensile resilience, when in use, automatic winding and unwinding can be realized under the action of self resilience force, a cable drum is not required to be additionally arranged, the use is convenient, the abrasion to the cable body is reduced, the service life is prolonged, and the use cost is reduced; and through setting up the outer jacket and supporting the packing element, not only increased the stability of cable body inner structure, but also promoted the elasticity and the flexibility of cable body self, strengthened the ability that the cable body is stretched and crooked repeatedly, make its elasticity keep permanent, the security is good, satisfies the requirement of cable body to resilience and tensile strength.
