Large-scale enterprise starts largely to be equipped with charging pile in original filling-up area.With the construction of the infrastructure such as charging pile, be badly in need of with
Its matching used mature cable product occurs.
In air due to the exposure of charging pile cable use environment, and often by bending, the various outer masterpieces such as pull, roll
With especially cable is the main problem of charging pile cable reduced service life often by pulling phenomenon, and current conventional electricity
Cable tensile capacity and mechanical performance are poor.
Summary of the invention
The purpose of this utility model is to provide a kind of charging pile tension shielding insulated cables, to solve existing charging
Stake cable there is because cable tensile capacity and mechanical performance it is poor, frequently pulled, rolled in use and cause to fill
The problem of electric stake cable reduced service life.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of charging pile tension shielding insulated cable, including core package, control conductor package, the core package are set
Several are equipped with, the core package is twisted by three cores in " product " font, and the is wrapped in outside the core package
One shielded layer, the core includes conductor, the inner insulating layer that is wrapped in outside conductor；
The control conductor package is by being arranged the control conductor of heart position in the cable and being wrapped in outside control conductor
The secondary shielding layer in portion is constituted；
External insulation layer, the external insulation layer external connection are wrapped in outside the first screen layer, control conductor package
It is enclosed with armor, flame retardant filler is also filled between the external insulation layer and armor, is wrapped in outside the armor resistance to
Grind protective case.
The external insulation layer is by several semi-circular projected parts, several arcs as a further improvement of the utility model,
Connected in star portion, several bar shaped extensions are constituted, several semi-circular projected parts are uniformly distributed along cable center's circumferencial direction, phase
It is connected between two adjacent semi-circular projected parts by arcuate recess sections, connected in star portion outward opening, several bar shapeds are stretched out
Portion is correspondingly arranged at the middle position of several arcuate recess sections.
The end of the bar shaped extension and armor, which support, as a further improvement of the utility model, closes.
Several core packages are correspondingly placed at several semi-circular projected parts as a further improvement of the utility model,
In several empty slots being inside provided with.
The flame retardant filler is low smoke halogen-free flame-retardant polyolefin particle as a further improvement of the utility model,.
The armor is woven by soft finer wire as a further improvement of the utility model,.
The wear-resistant protection set is made of pvc material as a further improvement of the utility model,.
The beneficial effects of the utility model are:
Compared with prior art, the utility model setting is twisted core package in " product " font by three cores, increases
The tension of strong conductor drags ability, is not pulled off easily, then be provided with the external insulation layer of several bar shaped extensions, further
It is whole to enhance cable, for being rolled with very strong adaptability；Solving existing charging pile cable, there is because of cable
Tensile capacity and mechanical performance are poor, are frequently pulled, are rolled in use and charging pile cable service life is caused to contract
Short problem.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the cross-sectional structure schematic diagram of the utility model；
Fig. 2 is the cross-sectional structure schematic diagram of external insulation layer in the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face is further described the utility model in conjunction with attached drawing and embodiment.
As shown in Figure 1 to Figure 2, a kind of charging pile tension shielding insulated cable, including core package, control conductor packet
Group, there are five the core package settings, and the core package is twisted by three cores in " product " font, the core packet
Group is external to be wrapped in first screen layer 3, and the core includes conductor 1, the inner insulating layer being wrapped in outside conductor 12；The core
Package, which is twisted by three cores in " product " font, to be advantageous in that and enhances its tensile capacity, in frequent pull, no
It can be broken easily.
The control conductor package is by being arranged the control conductor 4 of heart position in the cable and being wrapped in control conductor 4
External secondary shielding layer 5 is constituted；The centrally disposed place of the control conductor 4 be advantageous in that be capable of providing the effect of inner support with
And it is not easy to break.
It is wrapped in external insulation layer 6 outside the first screen layer 3, control conductor package, connects outside the external insulation layer 6
