Abstract
The utility model relates to an ultra-soft helical cable which consists of an insulated wire core, a shielding layer and a protective sleeve layer, wherein the external side of the insulated wire core sequentially is wrapped with the shielding layer and the protective sleeve layer; the insulated wire core consists of an internal conductor and an insulated layer which wraps the internal conductor; and the internal conductor is a structure of stranded tough copper wires with aramid fibers knitted outside. By aiming at the use characteristic of the helical cable used in the communication field, the ultra-soft helical cable is researched and prepared specially. The cable has the characteristics of excellent electrical performance, mechanical performance, environment resistance, chemical resistance, strong shielding performance and the like, and can completely meet the use requirements of communication sites in which the bending and moving operation is frequently carried out.
Description
Technical field
The utility model relates to field of telecommunications cables, especially a kind of super gentle spiral cable that is applicable to the communications field.
Background technology
Spiral cable is a kind of telecommunication cable that is applicable to the communications field, it forms by one or a few insulated wire cores is stranded usually, and cable is through twining heat treatment, final cooling shaping, form the scalable spiral status of similar rope, so we are referred to as spiral cable.Along with the development of society, spiral cable progressively increases progressively in the demand in fields such as transducer, medical treatment and illumination.Existing spiral cable is subjected to structural limitations, causes it in use to have a bigger defective, and promptly pliability is relatively poor, and often bend tension can cause cable impaired, is not suitable for using at the frequent bending of needs, stretching and mobile communication situation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of have good bendability, flexibility and elasticity are provided, the super gentle spiral cable that the communication situation that is adapted at needing frequent bending, stretch and move uses.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of super gentle spiral cable, constitute by insulated wire cores, screen and restrictive coating, the outside of insulated wire cores is wrapped up screen and restrictive coating successively, and insulated wire cores is made of inner wire and its outer insulating barrier of parcel, and it is characterized in that: inner wire is that stranded tough copper wire weaves aramid fiber silk structure outward.
And described insulated wire cores is 1 ~ 12, and its outside is wrapped up screen and restrictive coating jointly successively.
And described screen adopts tinned copper wire and aramid fiber silk weaving structure.
And described restrictive coating is the flame retardant polyurethane restrictive coating.
Advantage of the present utility model and beneficial effect are:
1, the inner wire of this cable adopts stranded tough copper wire to weave aramid fiber silk structure outward, so this cable has advantages such as flexibility is good, tensile strength is high, in light weight than traditional cable, and more being applicable to needs the frequent communication situation that moves.
2, the screen of this cable adopts tinned copper wire and aramid fiber silk weaving structure, makes flexibility of this cable and bendability obtain bigger lifting, both guaranteed the reliability of signal transmission, has strengthened again that cable stretches repeatedly and the ability of bending.
3, the restrictive coating of this cable adopts the flame retardant polyurethane material to make, make cable have excellent environment resistant, chemical resistance, prolonged the Acceptable life of cable, compare with the conventional helical cable and to have better spring performance and heavy burden intensity, and it is permanent that elasticity keeps, fail safe is good, can satisfy the requirement of spiral cable to resilience and tensile strength fully.
4, the tensile elongation of this cable can reach 5 times of former spiral cable length, and has good resilience force, and folding and unfolding is no longer in disorder, and this structure makes the use of movable equipment become more convenient, and equipment integral is more attractive in appearance.
5, the utility model is the handling characteristics at the employed spiral cable in the communications field, a kind of super gentle spiral cable that especial manufacture goes out.This cable has characteristics such as excellent electric property, mechanical performance, anti-environment, chemical-resistance and shielding are strong, the instructions for use in the communication place of can satisfy frequent bending fully, moving.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of super gentle spiral cable is made of insulated wire cores, screen 5 and restrictive coating 1, and the outside of insulated wire cores is wrapped up screen and restrictive coating successively, and insulated wire cores is made of inner wire and its outer insulating barrier 3 of parcel.In actual processing, insulated wire cores is generally 1 ~ 12, is four shown in the present embodiment, and its outside is wrapped up screen and restrictive coating jointly successively.
Innovative point of the present utility model is: inner wire is stranded tough copper wire 2 outer braiding aramid fiber silk 4 structures.Screen adopts tinned copper wire and aramid fiber silk weaving structure.Restrictive coating is the flame retardant polyurethane restrictive coating.
This cable twines bending with certain bending radius after Overheating Treatment, cooling shaping form spiral.Cable can stretch repeatedly, and elastic force is lasting, and the resilience excellence is through frequently stretching, crooked indeformable.
Claims (4)
1. super gentle spiral cable, constitute by insulated wire cores, screen and restrictive coating, the outside of insulated wire cores is wrapped up screen and restrictive coating successively, and insulated wire cores is made of inner wire and its outer insulating barrier of parcel, and it is characterized in that: inner wire is that stranded tough copper wire weaves aramid fiber silk structure outward.
2. super gentle spiral cable according to claim 1 is characterized in that: described insulated wire cores is 1 ~ 12, and its outside is wrapped up screen and restrictive coating jointly successively.
