Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in FIG. 1 to FIG. 2, a kind of preferred structure of tensile wear-resistant ant proof flexible cable described in the utility model.
As shown in Figure 1, the tensile wear-resistant ant proof flexible cable includes being filled out by interior from the compound cable core set gradually outside, insulation
Fill layer 2, wrapped belt 3, sheath internal layer 4 and wear resistant outer layer 5.
Wherein, the compound cable core is made of several cables 1, and 1 quantity of cable is excellent with 2~5.As shown in Figure 1, this reality
Applying example is 3 cables 1.
As shown in Fig. 2, each cable 1 include by it is interior from set gradually outside core 11, polypropylene rope filled layer 12 and absolutely
Edge wearing layer 13.The core 11 is conductive carrier, is drawn into copper wire and through being twisted for oxygen-free copper bar.In 11 stranding of core
In the process, the outer surface of core 11 is wrapped using polypropylene rope, then is wrapped with insulation wearing layer 13.This is those skilled in the art
Member is enforceable according to technical solution, omits description thus.
Preferably, the insulation wearing layer 13 is made of nylon.
Existing flexible cable focuses on improveing the performance of cable outer layer, sheath internal layer 4, and improving and optimizating to core 11
It is few.It is designed by this, the structure of each cable 1 is optimized, reinforce the protection to core 11.Meanwhile nylon have it is excellent
Corrosion-resistant and wear-resisting performance, made insulation wearing layer 13 make the toughness of cable 1 improve, is wear-resisting and termite-proof.Work as cable
Outer layer, sheath internal layer 4 damage, and insulation wearing layer 13 also can greatly avoid core 11 exposed, avoid that accident occurs.
As shown in Figure 1, insulation fill stratum 2 is filled in wrapped belt 3 and meets in the gap of cable core.Also, it is filled out in insulation
The inside for filling layer 2 also fills up several wirerope 21 by uniform ring around compound cable core.The skill of insulation fill stratum 2 and wirerope 21
Art scheme is that those skilled in the art is enforceable.
It is designed by this, wirerope 21 is set in insulation fill stratum 2, the tensile strength with higher of wirerope 21 resists
Fatigue strength and toughness.Insulation fill stratum 2 is combined with wirerope 21, can greatly improve the pull resistance of cable, simultaneously
Also flexibility required for flexible cable is kept.But also cable has excellent fatigue resistance and toughness.
Meanwhile applicant obtains by experiment, and the flexible cable of wirerope 21 is added, can transmit the load of long range,
It avoids drawing or pulling the damage to flexible cable.The self weight weight of flexible cable is reasonable, easy to carry and transport.Also, according to soft
Mechanical external force suffered by cable is divided into light-duty, medium-sized and heavy three classes on product structure.The utility model copes with different classes
Type provides the optional scheme of wirerope 21, to cope with the demand of different field, make this flexible cable have good versatility,
Series specification is complete, tensile property is good etc..
Preferably, the wirerope 21 is that 37 steel wires or 61 steel wires are twisted.
In the present embodiment, using three wirerope 21, at equal intervals around compound cable core.
In the present embodiment, insulation fill stratum 2 can be sector packing made of rubber, such as PE；Insulation fill stratum 2
It can be polypropylene rope filling.
As shown in figure 3, this implementation is preferably, a gasket for packing 22 is additionally provided in the centre bit of compound cable core.The filling
Rope 22 has certain tension and toughness, can restrict for the rope made of hemp, PP etc..
Preferably, the wirerope that the gasket for packing 22 can be twisted for 7 steel wires, 19 steel wires or 37 steel wires.7
Gasket for packing diameter obtained by steel wire, 19 steel wires or 37 steel wires is smaller, light-weight, does not increase the outer diameter of cable, and more
The big tensile property that improves is to protect compound cable core.The combination of wirerope and gasket for packing, tensile property are more preferable etc..
Wherein, the wrapped belt 3 is preferably the wrapped formation of non-woven fabrics.The tensile strength of non-woven fabrics is high, and elongation is low,
The tension that band is increased when being conducive to stranding band, promotes that cable core is even closer, rounding, can reduce the outer diameter of cable, reduce electricity
The cost of cable.Non-woven fabrics has good flexibility, does not occur to tear phenomenon increased bandwidth, productivity can be improved.
Wherein, the sheath internal layer 4 is made of PVC material.
Wherein, the wear resistant outer layer 5 is made of nylon material.Nylon have excellent low smoke and zero halogen, it is nontoxic, cold-resistant (- 70
DEG C), heat-resisting (180 DEG C), weatherability, corrosion-resistant and wear-resisting performance.Made cable surface is smooth, good toughness, Ke Yiqi
To function wear-resisting and termite-proof well.
The combination of wear resistant outer layer 5 and the wearing layer 13 that insulate, plays the role of double shielding cable core.Increase the wearability of cable
Can, it reduce the probability that is exposed and causing contingency of core 11.Meanwhile wear resistant outer layer 5 and insulation wearing layer 13 are nylon, are mentioned
The service life of high flexible cable reduces maintenance cost.
A kind of tensile wear-resistant ant proof flexible cable working principle described in the utility model is:
Wirerope is added in flexible cable as tension members, reinforces the tensile capacity of flexible cable.Meanwhile wear resistant outer layer with
The dual structure of insulation wearing layer uses, and flexible cable can cope with the construction environment and form of construction work of very severe.Flexible cable tool
Have that certain flexibility, tensile strength are good, but also flexible cable has excellent fatigue resistance and toughness.
A kind of other structures of tensile wear-resistant ant proof flexible cable described in the present embodiment are referring to the prior art.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, therefore it is all without departing from the content of the technical scheme of the utility model, implement according to the technical essence of the utility model to above
Any modification, equivalent variations and modification, are still within the scope of the technical solutions of the present invention made by example.
