Description

A kind of stretch-proof braid

Technical field

The utility model is related to field of cables, espespecially a kind of stretch-proof braid.

Background technology

With the development of society, cable is typically by several or the cable of similar rope made of several groups of wire strandings, often Mutually insulated between group conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Cable has There are interior energization, the feature of external insulation.Cable has power cable, control cable, compensating cable, shielded cable, high-temperature cable, calculating Electric cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They be all by Sub-thread or stranded conductor and insulating layer composition, for connecting circuit, electric appliance etc..

Existing cable is often mating with big machinery, needs frequent movement, bears larger pulling force, and flexibility is not It reaches, is easy tension failure or bending fractures so that traditional cable service life is not grown, and the use of mechanical equipment is influenced.

Invention content

It is light-weight to solve the above problems, the utility model provides a kind of stretch-proof braid, Tensile strength it is big and Flexibility is good.

To achieve the above object, the technical solution adopted in the utility model is：A kind of stretch-proof braid, including line Core, insulating layer, braiding layer, the core are twisted by stranded conductor, and the insulating layer is wrapped in core, the braiding layer packet Insulating layer is wrapped up in, the braiding layer is cylindrical shape, and the braiding layer includes PVC braid over braids and woven fabric braid over braid, and the PVC is compiled Ribbon is different from woven fabric braid over braid color, and the PVC braid over braids and woven fabric braid over braid alternate braiding around insulating layer.

Specifically, the insulating layer includes interior thin layer, foaming layer and outer thin layer successively from inside to outside.

Specifically, the interior thin layer is interior thin layer made of insulation compact substance material, and the foaming layer is made of expanded material Foaming layer, the outer thin layer be insulation compact substance made of outer thin layer.

Specifically, the braiding layer surface is equipped with transparent sheath.

Specifically, the core is copper, aluminium or coated metal.

Specifically, the braiding layer surface is additionally provided with gluing.

Specifically, the core is single, two cores, three cores or seven cored structures.

The beneficial effects of the utility model are：The braiding layer of the utility model braid outer layer by PVC braid over braids and Woven fabric braid over braid weaves, and has good Tensile strength and flexibility, while than lighter, when use is not allowed easy-to-draw yet It stretches fracture or bending fractures, ensure service life, and PVC braid over braids are different from woven fabric braid over braid color, appearance is more beautiful, With better visual effect.

Specific implementation mode

It please refers to Fig.1 with shown in Fig. 2, the utility model is about a kind of stretch-proof braid, including core 1, insulating layer 2, braiding layer 3, the core 1 are twisted by stranded conductor, and the insulating layer 2 is wrapped in core 1, and the braiding layer 3 is wrapped up Insulating layer 2, the braiding layer 3 is cylindrical shape, and the braiding layer 3 includes PVC braid over braids 31 and woven fabric braid over braid 32, described PVC braid over braids 31 are different from 32 color of woven fabric braid over braid, and the PVC braid over braids 31 and woven fabric braid over braid 32 surround 2 phase of insulating layer Mutually alternately weave.

Compared with prior art, the braiding layer 3 of the utility model braid outer layer is woven by PVC braid over braids 31 and woven fabric Band 32 weaves, and has good Tensile strength and flexibility, while also than lighter, when use is not easy tension failure Or bending fractures, and ensures service life, and PVC braid over braids 31 are different from 32 color of woven fabric braid over braid, appearance is more beautiful, tool There is better visual effect.

Specifically, the insulating layer 2 includes interior thin layer 21, foaming layer 22 and outer thin layer 23 successively from inside to outside.

Wherein, the interior thin layer 21 is interior thin layer 21 made of insulation compact substance material, and the foaming layer 22 is expanded material Manufactured foaming layer 22, the outer thin layer 23 are outer thin layer 23 made of insulation compact substance.

Using the above scheme so that also than lighter while insulating layer 2 has good insulating properties.

Specifically, 2 surface of the braiding layer is equipped with transparent sheath 4.

Using the above scheme, it further protects and is not corroded and rubbed inside cable, ensure the service life of cable.

Specifically, the core 1 is copper, aluminium or coated metal.

Specifically, 3 surface of the braiding layer is additionally provided with gluing.

Using the above scheme, there is insulative water-proof and moisture resistance effect

Specifically, the core 1 is single, two cores, three cores or seven cored structures.

The utility model is further described below by specific embodiment.

This specific embodiment includes core 1, insulating layer 2, braiding layer 3 and transparent sheath 4, and wherein core 1 is by stranded conductor It being twisted, insulating layer 2 is wrapped in core 1, and braiding layer 3 is wrapped in insulating layer 2, and transparent sheath 4 is wrapped in braiding layer 3,；Its In, 3 outer surface of braiding layer is cylindrical shape so that cable surface is round and smooth, good hand touch；In addition, braiding layer 3 includes different colours PVC braid over braids 31 and woven fabric braid over braid 32, PVC braid over braids 31 and woven fabric braid over braid 32 alternate braiding around insulating layer, tool There are good Tensile strength and a flexibility, when use, is not easy tension failure or bending fractures, and ensures service life, while Than lighter, mitigate the overall weight of equipment.

In this embodiment, insulating layer 2 include successively from inside to outside by insulation compact substance material be made interior thin layer 21, by Foaming layer 22 and the outer thin layer 23 made of insulation compact substance made of expanded material, core 1 are three-core structure.

Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine It protects in range.
