Description

Cable not prone to cracking for real estate

Technical Field

The utility model relates to the technical field of cables, specifically be a real estate is with cable that is difficult for fracture.

Background

When the external diameter of cable is great, the armor generally adopts double-deck steel band clearance to wrap around to form, and the sheath generally adopts crowded tubular or half crowded tubular mould to extrude. The larger the thickness of the armor steel belt is, the stronger the rigidity is, the worse the plasticity is, the rebound tendency in the wrapping process is increased, the external tension born by the sheath is increased, and the height difference between the upper layer steel belt and the lower layer steel belt on the surface of the armor layer is large. In order to solve the problem of cracking of a cable with a large outer diameter, the company carries out research on a cable which is not easy to crack and used for real estate.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a real estate with cable that is difficult for the fracture, avoid armor and contact on every side through adding the buffer layer, the fracture of outer protective layer has been avoided to the atress that from this can effectual reduction outer protective layer, can effectively solve the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the cable comprises a cable core, wherein an inner protective sleeve wraps the outside of the cable core, an inner liner wraps the outside of the inner protective sleeve, an armor wraps the outside of the inner liner, and an outer protective layer wraps the outside of the armor;

the armor comprises a fiber woven layer, and buffer layers are arranged on two sides of the fiber woven layer;

and filling is arranged between the protective sleeve and the inner liner layer, and the filling is of a honeycomb structure.

As an optimized technical proposal of the utility model, the fiber weaving layer adopts any weaving of glass fiber, copper fiber and steel fiber.

As an optimized technical scheme of the utility model, the buffer layer adopts arbitrary one in poly vinegar area, non-woven fabrics, the low smoke glass ribbon of halogen-free, the polyolefin area.

As an optimal technical scheme of the utility model, the inner liner is insulating layer, bag, inner sheath, waterproof layer and oxidation resisting layer by interior outside to in proper order.

Compared with the prior art, the beneficial effects of the utility model are that: according to the cable not prone to cracking for the real estate, 1, the buffer layer is added between the armor layer and the outer protection layer, a certain buffering effect can be achieved, so that the stress of the outer protection layer is reduced, and the armor layer can be effectively prevented from cracking to scratch the outer protection layer; 2. the armor layer is woven by fibers, so that the thickness of the armor layer can be ensured, the rigidity of the armor layer can be effectively reduced, and the plasticity of the armor layer is improved; 3. a buffer layer is also arranged between the armor layer and the inner liner layer, so that the extrusion force applied to the inner liner layer can be effectively reduced; 4. the whole flat structure setting that adopts for the atress of inner liner, armor and outer protective layer is comparatively even when taking place to buckle.

Fig. 2 is a schematic view of the internal structure of the tangent plane of the present invention.

In the figure: 1 cable core, 11 wires, 12 fillers, 2 inner protective sleeves, 3 fillers, 31 honeycomb structures, 4 lining layers, 41 insulating layers, 42 wrapping bags, 43 inner protective sleeves, 44 waterproof layers, 45 oxidation resistant layers, 5 armoring, 51 fiber weaving layers, 52 buffer layers and 6 outer protective layers.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a cable which is not easy to crack for real estate comprises a cable core 1, wherein an inner protective sleeve 2 wraps the outside of the cable core 1, an inner liner 4 wraps the outside of the inner protective sleeve 2, an armor 5 wraps the outside of the inner liner 4, and an outer protective layer 6 wraps the outside of the armor 5;

the armor 5 comprises a fiber woven layer 51, buffer layers 52 are arranged on two sides of the fiber woven layer 51, the armor 5 is woven by the fiber woven layer 51, the thickness of the armor can be guaranteed, the rigidity of the armor can be effectively reduced, the plasticity of the armor can be improved, and the buffer layers 52 are arranged on two sides of the fiber woven layer 51, so that the inner lining layer 4 and the outer protection layer 6 can be effectively prevented from being damaged;
