Description

Engineering machinery anti-torsion flexible cable

Technical field

The utility model is related to the design field of engineering machinery cable.

Background technology

With expanding economy and the raising of national life level, mechanization degree has obtained very big development, particularly Mechanical automation makes great progress.Also roll up for the cable in mechanical automation equipment, particularly movable machine Tool arm consumption is more.And the cables most of mechanical arm is all common Plastic-sheathed Cable in mechanical strength, resistance to ring at present There are many defects in the aspects such as border.The conventional cable of current mechanical arm is big due to activity, often bending, the shield of cable Jacket layer occurs crackle, and internal structure occurs loose or phenomenon of rupture.Cable through just must more renew after a while, High cost is caused, inconvenience is used.

Utility model content

The utility model purpose is for problem above, there is provided a kind of electricity with anti-torsion excellent performance, resistance to environment Cable, can substantially reduce the engineering machinery anti-torsion flexible cable of use cost.

The utility model includes cable core, and reinforced lapping layer, fiber braiding layer and outer are orderly arranged outside each in the cable core Restrictive coating；Count >=50% of the fiber braiding layer, in the external sheath layer, in the symmetrical parallel setting in cable core both sides A pair of mixing twisted wires；The mixing twisted wire includes mutually stranded steel wire, fiber, sets poly- on the outside of stranded steel wire and fiber Ester belting layer；The cable core includes center-filled layer, and insulated wire cores are set within one week in the outside of center-filled layer, described exhausted The radical of edge core is even number；Per share insulated wire cores include conductor respectively, and insulating barrier is set on the outside of conductor.

The utility model is provided with the big plastic cement center-filled layer of flexibility high-tensile at the center of cable, so as to strengthen The flexibility of cable；From thermoplastic elastomer (TPE) as insulating barrier, it is ensured that the good wearability of insulating barrier；Fiber braiding layer is protected Intensity of the cable when frequently bearing to reverse and bend has been demonstrate,proved, the stress of insulated wire cores is minimized；Symmetrically put down cable core both sides The mixing twisted wire that row is placed, can carry out specification adjustment with the difference that is different, bearing pulling force of use occasion.The utility model has There are anti-torsion excellent performance, the cable of resistance to environment, use cost can be substantially reduced.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

As shown in figure 1, the utility model includes cable core, reinforced lapping layer 1, fibrage is orderly arranged outside each in cable core Layer 2 and external sheath layer 3；Count >=50% of fiber braiding layer 2；Set in external sheath layer 3, in cable core both sides are symmetrical parallel Put a pair of mixing twisted wires 4；Mixing twisted wire 4 includes mutually stranded steel wire, fiber, sets poly- on the outside of stranded steel wire and fiber Ester belting layer 5；Cable core includes center-filled layer 6, and insulated wire cores 7, insulated wire cores 7 are set within one week in the outside of center-filled layer 6 Radical be even number；Per share insulated wire cores 7 include conductor 8 respectively, and insulating barrier 9 is set in the outside of conductor 8.
