Abstract
The utility model discloses a kind of self-supporting data cable, comprises that steel wire and 2 are coated with the copper conductor of polyethylene layer, and the first restrictive coating is coated on 2 described copper conductor outer surfaces, and the second restrictive coating is coated on steel wire outer surface; One bar shaped connecting portion is between the first restrictive coating and the second restrictive coating, and this bar shaped connecting portion arranged on left and right sides is equipped with v-depression, and some polyethylene fibres are positioned at the first restrictive coating and circumferentially evenly distributed along the first restrictive coating; The number of described polyethylene fibre is 8.The utility model self-supporting data cable is in the time ensureing that under tension is torn, cable is easy to just separated and can not destroy the cable core of cable, also ensure that cable is without elongation strain, form the overcoat with desirable stretch-proof bending resistance, reduced greatly the external diameter of cable.
Description
Technical field
The utility model relates to a kind of self-supporting cable, relates in particular to a kind of self-supporting data cable.
Background technology
The unbraced element of available data cable own, data cable install and laid processes in, its tensile strength is very limited, and must be noted that too to exert oneself, otherwise can destroy structure and the performance of cable when construction, and transmission quality is made a big impact.Owing to can not too exerting oneself, draw in order to prevent from pulling, must poling when installation or be placed in cable unwrapping wire groove, so must carry out pipeline or the wire casing installment work in early stage, waste of manpower like this, material resources when cable is installed.
Summary of the invention
The utility model provides a kind of self-supporting data cable, this self-supporting data cable is in the time ensureing that under tension is torn, cable is easy to just separated and can not destroy the cable core of cable, also ensure that cable is without elongation strain, formation has the overcoat of desirable stretch-proof bending resistance, has reduced greatly the external diameter of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self-supporting data cable, comprise that steel wire and 2 are coated with the copper conductor of polyethylene layer, the first restrictive coating is coated on 2 described copper conductor outer surfaces, and the second restrictive coating is coated on steel wire outer surface; One bar shaped connecting portion is between the first restrictive coating and the second restrictive coating, and this bar shaped connecting portion arranged on left and right sides is equipped with v-depression, and some polyethylene fibres are positioned at the first restrictive coating and circumferentially evenly distributed along the first restrictive coating.
In technique scheme, further improve technical scheme as follows:
1. in such scheme, described V-type recess width is 0.2 ~ 0.5mm, and the degree of depth is 0.2 ~ 0.5mm.
2. in such scheme, the number of described polyethylene fibre is 8.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model self-supporting data cable, ensureing on the basis of self-supporting cable tensile strength, by adopting the one V-type groove of the each increase in both sides in the middle of neck, V-type recess width 0.2 ~ 0.5mm, the degree of depth 0.2 ~ 0.5mm, due to the existence of groove, when cable is torn under tension, stress point all can concentrate on V-type groove part, and cable is easy to just separated, and can not destroy the cable core of cable; The successful exploitation of the utility model technology, in having ensured cable performance, greatly facilitates cable construction, has solved that traditional 8 word cables are not easily separated in the time tearing, the shortcoming of destructible cable core, has promotion prospect widely.
2. the utility model self-supporting data cable, some polyethylene fibres are positioned at the first restrictive coating and circumferentially evenly distributed along the first restrictive coating, ensure that cable is without elongation strain, formation has the overcoat of desirable stretch-proof bending resistance, also reduced greatly the external diameter of cable, increase cable because stretching affects the ability of serviceability, improved the flexibility of outside cable, ensured that cable is without elongation strain.
Brief description of the drawings
Accompanying drawing 1 is the utility model self-supporting data cable structural representation.
In above accompanying drawing: 1, steel wire; 2, copper conductor; 21, polyethylene layer; 3, the first restrictive coating; 4, the second restrictive coating; 5, bar shaped connecting portion; 6, v-depression; 7, polyethylene fibre.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment 1: a kind of self-supporting data cable, comprise that copper conductor 2, the first restrictive coatings 3 that 1 and 2, steel wire is coated with polyethylene layer 21 are coated on 2 described copper conductor 2 outer surfaces, the second restrictive coating 4 is coated on steel wire 1 outer surface; One bar shaped connecting portion 5 is between the first restrictive coating 3 and the second restrictive coating 4, and these bar shaped connecting portion 5 arranged on left and right sides are equipped with 6,8 polyethylene fibres 7 of v-depression and are positioned at the first restrictive coating 3 and circumferentially evenly distributed along the first restrictive coating 3.
Embodiment 2: a kind of self-supporting data cable, comprise that copper conductor 2, the first restrictive coatings 3 that 1 and 2, steel wire is coated with polyethylene layer 21 are coated on 2 described copper conductor 2 outer surfaces, the second restrictive coating 4 is coated on steel wire 1 outer surface; One bar shaped connecting portion 5 is between the first restrictive coating 3 and the second restrictive coating 4, and these bar shaped connecting portion 5 arranged on left and right sides are equipped with v-depression 6, and some polyethylene fibres 7 are positioned at the first restrictive coating 3 and circumferentially evenly distributed along the first restrictive coating 3.
Above-mentioned V-type groove 6 width are 0.2 ~ 0.5mm, and the degree of depth is 0.2 ~ 0.5mm.
While adopting above-mentioned self-supporting data cable, ensureing on the basis of self-supporting cable tensile strength, by adopting the one V-type groove of the each increase in both sides in the middle of neck, V-type recess width 0.2 ~ 0.5mm, the degree of depth 0.2 ~ 0.5mm, due to the existence of groove, when cable is torn under tension, stress point all can concentrate on V-type groove part, and cable is easy to just separated, and can not destroy the cable core of cable; The successful exploitation of the utility model technology, in having ensured cable performance, greatly facilitates cable construction, has solved that traditional 8 word cables are not easily separated in the time tearing, the shortcoming of destructible cable core, has promotion prospect widely; Secondly, some polyethylene fibres are positioned at the first restrictive coating and circumferentially evenly distributed along the first restrictive coating, ensure that cable is without elongation strain, formation has the overcoat of desirable stretch-proof bending resistance, also reduced greatly the external diameter of cable, increase cable because stretching affects the ability of serviceability, improved the flexibility of outside cable, ensured that cable is without elongation strain.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
