Description

A kind of portable twisted telephone wire of softness tension

Technical field

The utility model relates to a kind of telephone wire, the portable twisted telephone wire of specifically a kind of softness tension belongs to cable Manufacturing technology field.

Background technique

With the fast development of electric power and the communications industry, cable applies increasingly extensive, becoming increasingly complex for use occasion, right The requirement of cable is also more harsh.Particularly with have it is aerial, pull laying occasion telephone communication line, to high tensile, light weight, It is small in size, reliability is high etc., and indexs have very high requirement.The telephone wire of existing tension occasion laying mostly uses high strength steel Silk reinforcer, to achieve the effect that product tension.But since steel wire hardness itself is higher, quality is larger, cause product curved Bent relatively difficult, heavier mass, is not able to satisfy some Special use occasions with the requirements such as softness, tension, portable.For example, Increase high-tensile steel wires, achieve the effect that product tension, using stranded conductor, soft insulating sheath material reaches similar soft Soft purpose.But the weight of product itself is increased due to steel wire specific gravity itself as reinforcer using high-tensile steel wires, Since high-tensile steel wires hardness is larger, even if using stranded conductor, soft insulating sheath material, it is also difficult to reach soft and want It asks.

Utility model content

The purpose of the utility model is to provide a kind of light weights, the portable twisted telephone wire of soft tension small in size.

In order to reach above-mentioned technical purpose, the technical solution of the utility model is:

A kind of portable twisted telephone wire of softness tension, including two insulated wire cores, described two insulated wire cores are stranded in Together, the insulated wire cores are followed successively by conductor and insulating layer from inside to outside, and the conductor is stranded conductor, in the stranded conductor Between and conductor and insulating layer between be provided with the nonmetallic strengthening core of aramid fiber.

It replaces high-strength galvanized steel wire as telephone wire tensile elements using the nonmetallic strengthening core of aramid fiber, reaches product tension With soft requirement；Using the nonmetallic strengthening core of aramid fiber, material intensity height itself, specific gravity and small in size, virtue in every kilometer of product The weight of synthetic fibre can be ignored substantially, achieve the purpose that portable；Using aramid fiber, stranded conductor, softness insulating sheath material, really Reach soft purpose.

The utility model uses the nonmetallic strengthening core of aramid fiber, and insulation thickness minimum thickness is 0.2mm, reduces product weight and reaches To portable effect, while using nonmetallic strengthening core, the insulating sheath material of stranded conductor and softness, reach soft effect Fruit, to obtain light weight, small in size, soft tension, the telephone wire being convenient for carrying.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Specific embodiment

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

As shown in Figure 1, a kind of portable twisted telephone wire of softness tension, including two insulated wire cores, described two insulation Core twists together, and twisted using two core insulation cores, the electric property of telephone wire is more stable, is twisted using two core insulation cores It closes, flexibility, the resistance to bend(ing) of telephone wire can be more preferable.

The insulated wire cores are followed successively by conductor 1 and insulating layer 3 from inside to outside, and the conductor 1 is stranded conductor, insulating layer 3 Using soft insulating sheath material, insulating layer 3 is with a thickness of 0.2mm, between the stranded conductor and conductor 1 and insulating layer The nonmetallic strengthening core 2 of aramid fiber is provided between 3.

Above-described embodiment does not limit the utility model in any way, all by the way of equivalent substitution or equivalent transformation The technical solution of acquisition is all fallen in the protection scope of the utility model.
