The utility model discloses the cable possesses good anti -interference ability, operation safety.
Description
Technical field
The utility model belongs to automobile cable and manufactures field, is specifically related to a kind of AC charging charging pile composite cable.
Background technology
The starting stage is at home for the charging cable transmitting dynamic power and signal controlling in current new energy vehicle charging system, the main dependence on import of product, domestic have Some Enterprises also to develop portioned product, but the comprehensive function of its product, softness, easily dragging installation capability and antijamming capability also do not reach the technical merit of same kind of products at abroad far away, do not belong to qualified products truly.
For the cable in new-energy automobile charging system, the several functions such as electric power transfer, signal controlling and transmission need be had because of it, and larger current-carrying capacity, electromagnetism interference, softness need be possessed, under the condition dragged, the performance such as to use, so need to carry out the aspect Functional Designs such as synthesization structure, electromagnetism interference; Also to ensure the properties such as cable has high temperature resistant, flame resistant, resistance toly to dawdle, environmental protection simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of AC charging charging pile composite cable, and cable possesses good interference free performance, security of operation.
The utility model takes following technical scheme: a kind of AC charging charging pile composite cable, and comprise cable core, separator and oversheath, described cable core, separator and oversheath are radially arranged successively from inside to outside; It is characterized in that: described cable core comprises 3 root unit cables, described unit cable twisting is shaping, and be centrosymmetric distribution.
Described unit cable includes conductor and insulating barrier; Described conductor adopts thermoplasticity or thermo-setting elastomer for annealing bare copper conductor or zinc-plated annealed copper conductor, described insulating barrier, is closely extruded on conductor.
Described separator is close to the vertical bag of cable core by some layers of nonwoven fabrics band or is wrappedly formed.
Described oversheath adopts thermoplasticity or thermo-setting elastomer, and oversheath is closely extruded on separator.
In described cable core, between each unit cable, gap is provided with filler; Described filler is fluoroplastics material inserts.
As preferably, described insulating barrier adopts TPE-S type thermoplastic elastomer (TPE).
As preferably, described separator adopts fire retardant nonwoven fabric band, and separator is close to the vertical bag of cable core or is wrappedly formed, and the wrapped rate of putting up is not less than 15%.
As preferably, described oversheath adopts TPE-S type thermoplastic elastomer (TPE).
The beneficial effects of the utility model: (1) adopts 3 root unit cable arrangements in same cable core, symmetrical in center geometry, make Electric Field Distribution and every electric parameter present symmetry and balance at threephase cable, transfer impedance is low, and high order harmonic component emission measure is low; (2) insulation and sheath have employed special modified thermoplasticity or thermoset elastomer materials, ensure that cable possesses the characteristic of highly-flexible, be easy to during use install, and there is the characteristics such as excellent fire-retardant, resistance to ozone, acid-alkali-corrosive-resisting, wear-resistant, high-low temperature resistant, environmental protection; (3) be provided with filler in cable core and can play protection against the tide, fire retardation, and improve cable core stranded after roundness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, a-unit cable, 1-conductor, 2-insulating barrier, 3-separator, 4-oversheath, 5-filler.
