Abstract
The utility model discloses a kind of 8 font self-supporting cables, comprises steel wire and 2 copper conductors that are coated with 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 described V-type recess width is 0.2 ~ 0.5mm, and the degree of depth is 0.2 ~ 0.5mm.The utility model is guaranteeing on the basis of self-supporting cable tensile strength, when cable is torn under tension, cable is easy to just separated, and can not destroy the cable core of cable, also greatly facilitate cable construction, solved that traditional 8 word cables are not easily separated when tearing, the shortcoming of destructible cable core, there is promotion prospect widely.
Description
Technical field
The utility model relates to a kind of self-supporting cable, relates in particular to a kind of 8 font self-supporting cables.
Background technology
The existing 8 font self-supporting constructions of cable are, cable core and self-supporting steel wire respectively sheath are together with 8 word textural associations, and the two Intermediate Gray connects neck.This kind of structure, when separated cable core and self-supporting line, can run into when neck is difficult for tearing and tears by force and can destroy cable core, affects the use of cable.
Summary of the invention
The utility model provides a kind of 8 font self-supporting cables, this 8 font self-supporting cable is guaranteeing on the basis of self-supporting cable tensile strength, when cable is torn under tension, cable is easy to just separated, and can not destroy the cable core of cable, also greatly facilitate cable construction, solved that traditional 8 word cables are not easily separated when tearing, the shortcoming of destructible cable core, there is promotion prospect widely.
For achieving the above object, the technical solution adopted in the utility model is: a kind of 8 font self-supporting cables, comprise steel wire and 2 copper conductors that are coated with 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.
In technique scheme, further improve technical scheme as follows:
In such scheme, described V-type recess width is 0.2 ~ 0.5mm, and the degree of depth is 0.2 ~ 0.5mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model 8 font self-supporting cables, guaranteeing on the basis of self-supporting cable tensile strength, by adopting the both sides in the middle of neck respectively to increase V-type groove one, 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, when having guaranteed cable performance, greatly facilitates cable construction, has solved that traditional 8 word cables are not easily separated when tearing, the shortcoming of destructible cable core, has promotion prospect widely.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model 8 font self-supporting construction of cable schematic diagrames.
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.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment 1: a kind of 8 font self-supporting cables, comprise that steel wire 1 and 2 copper conductor 2, the first restrictive coatings 3 that are coated with polyethylene layer 21 are coated on 2 described copper conductor 2 outer surfaces, and 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.
Embodiment 2: a kind of 8 font self-supporting cables, comprise that steel wire 1 and 2 copper conductor 2, the first restrictive coatings 3 that are coated with polyethylene layer 21 are coated on 2 described copper conductor 2 outer surfaces, and 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.
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 8 font self-supporting cable, guaranteeing on the basis of self-supporting cable tensile strength, by adopting the both sides in the middle of neck respectively to increase V-type groove one, 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, when having guaranteed cable performance, greatly facilitates cable construction, has solved that traditional 8 word cables are not easily separated when tearing, the shortcoming of destructible cable core, has promotion prospect widely.
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.
