Description
Technical field
A kind of electric wire is the utility model is related to, more particularly to a kind of two core electric wires.
Background technology
Authorization Notice No. is that CN202996341U utility model patent discloses a kind of multicore fire resistant electric wire.The practicality
It is new that a layer insulating has been coated in the outside of copper conductor, and it is surrounded by sheath on the outside of more cores.
But there is problems with the utility model：Need first to be cut off insulating barrier with scissors when stripping insulation layer
Then again the insulating barrier of cutting is pulled, be easy for during insulating barrier is cut off in no carrying special peeling tool
It is damaged the copper conductor of inside.
Utility model content
The purpose of this utility model is to provide a kind of two core electric wires, it is advantageous that will not make to lead when stripping insulation layer
Wire core is damaged.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of two core electric wires, bag
Two conductor wire cores are included, the outside of the every conductor wire core is provided with polyvinyl chloride insulation layer, in addition to by two with polychlorostyrene second
The pvc sheath layer of the conductor wire core bag of alkene insulating barrier internally, set every a segment distance on the polyvinyl chloride insulation layer
There is the annular formed together by multiple linear marks of break to reserve line.
By using above-mentioned technical proposal, with cutting when setting the reserved line of annular to need to strip out conductor wire core to come
After knife cuts off pvc sheath layer, polyvinyl chloride insulation layer is caught positioned at two side positions of the reserved line of annular, two hands
Reversely turning polyvinyl chloride insulation layer causes polyvinyl chloride insulation layer disconnects in the position of the reserved line of annular can be by polyvinyl chloride
Insulating barrier is deviate from.So there is no need to be gone to cut off polyvinyl chloride insulation layer with scissors, also can avoids conductor wire core from being damaged.
The utility model is further arranged to：On the polyvinyl chloride insulation layer bag is provided with the reserved line of per pass annular
The firmly pyrocondensation ring of the reserved line of annular.
By using above-mentioned technical proposal, set pyrocondensation ring to carry out pyrocondensation and be attached on polyvinyl chloride insulation layer positioned at annular reserved
The position of line, the reserved line fracture of annular is avoided to cause two conductor wire core contact short circuits of inside.
The utility model is further arranged to：The hand that the marginal position of the pyrocondensation ring is equipped with triangle tears breach.
By using above-mentioned technical proposal, pyrocondensation ring can be torn by hand by setting hand to tear breach, can be thus not required to
Pyrocondensation ring is cut off with scissors, it is more convenient when use.
The utility model is further arranged to：It is provided with the outside of the polyvinyl chloride insulation layer at the reserved line of per pass annular
Annular groove, the width of the annular groove are more than the width of pyrocondensation ring.
By using above-mentioned technical proposal so that pyrocondensation ring is stuck in annular groove, avoids pyrocondensation ring in polyvinyl chloride insulation
The position that axial float causes pyrocondensation ring to depart from the reserved line of annular occurs on layer.
The utility model is further arranged to：Adjacent annular described in per pass on polyvinyl chloride insulation layer reserves line spacing phase
Together and not on same radial section.
By using above-mentioned technical proposal, needed when connection due to two core electric wires by the tie point of two conductor wire cores
Position is staggered, therefore the reserved line of annular is arranged on different radial sections, and line is reserved by polyvinyl chloride insulation layer along annular
After disconnection, conductor wire core is cut in the position with a certain distance from from reserved lines, so that it may so that what four conductor wire cores exposed
Stagger position.
In summary, the beneficial effects of the utility model are：
1st, scissors need not be used when setting the reserved line of annular to cause stripping insulation layer on polyvinyl chloride insulation layer
Insulating barrier is cut, avoids conductor wire core from being damaged；
The 2nd, pyrocondensation ring is set to avoid the reserved line fracture of annular from causing two conductor wire core contact short circuits of inside.
Brief description of the drawings
Fig. 1 is the structural representation of the non-bag pyrocondensation ring of embodiment；
Fig. 2 is schematic diagram of the pyrocondensation ring bag in annular groove in embodiment.
Reference：1st, conductor wire core；2nd, polyvinyl chloride insulation layer；3rd, pvc sheath layer；4th, the reserved line of annular；5、
Annular groove；6th, pyrocondensation ring；7th, hand tears breach.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
As shown in figure 1, a kind of two core electric wires, including two conductor wire cores 1, every conductor wire core 1 are all twisted by more copper wires
Close and formed.The outside of every conductor wire core 1 is surrounded by polyvinyl chloride insulation layer 2 come so that being all mutually insulated between every two wires
, and the good heat-resistant aging of polyvinyl chloride causes polyvinyl chloride layer to be able to maintain that prolonged stable insulation.Two conductions
In core 1 is wrapped in by a strata vinyl chloride restrictive coating 3, the work of protection polyvinyl chloride insulation layer 2 and conductor wire core 1 is played
With.
As shown in figure 1, in order to be cut off when polyvinyl chloride insulation layer 2 is torn using scissors, in polychlorostyrene
The linear mark of break of multiple tracks is provided with to form the reserved line 4 of annular every the position of one end distance on ethene insulating barrier 2.Only need two hands
Polyvinyl chloride insulation layer 2 is caught reversely to turn polyvinyl chloride insulation layer positioned at the position of the reserved both sides of line 4 of annular, two hands respectively
2 cause polyvinyl chloride insulation layer 2 to be disconnected in the position of the reserved line 4 of annular.Adjacent annular on twice polyvinyl chloride insulation layer 2 is pre-
Stay the spacing of line 4 identical and not on same radial section, the fracture so disconnected will not be in same position so that wiring
When can be connected one by one with two conductor wire cores 1 of other two cores electric wires in different positions.
As depicted in figs. 1 and 2, the outside of polyvinyl chloride insulation layer 2 forms annular groove positioned at the position of the reserved line 4 of per pass annular
5, width cuts the pyrocondensation ring 6 to be formed less than the heat-shrink tube of annular groove 5 and is caught in the reserved line of annular after pyrocondensation in annular groove 5
4 block, and avoid the reserved line 4 of annular from being broken two contact short circuits of conductor wire core 1 for causing inside.The margin location of per pass pyrocondensation ring 6
Put and be provided with the hand of a triangle and tear breach 7 to be conveniently torn by hand pyrocondensation ring 6.
As depicted in figs. 1 and 2, when conductor wire core 1 is stripped out into next, pvc sheath layer 3 is cut off with scissors
After deviate from.Pyrocondensation ring 6 is torn in the position that breach 7 is torn then along hand, afterwards that polyvinyl chloride insulation layer 2 is reserved along annular
Abjection successfully can strip out the conductor wire core 1 of inside to come after the position of line 4 is twisted into two parts.
