Abstract
The invention relates to a strip-type fluoroplastic insulated cable which comprises a jacket and a plurality of conductive cores arranged in parallel, wherein, each conductive core is externally wrapped with an insulation layer that is externally wrapped with the flat jacket; the material of the insulation layer is fluoroplastics. The strip-type fluoroplastic insulated cable has simple structure and adopts fluoroplastics as the material of the insulation layers, thereby being characterized by high temperature and lower temperature resistance, moisture resistance, chemical drug corrosion resistance, light weight, as well as high strength, small volume, compact structure, and the like.
Description
Technical field
The present invention relates to the electric wire field, especially a kind of fluoroplastic insulated tape cable.
Background technology
Common flat cable all adopts common plasticses such as polyvinyl chloride or polyethylene to do insulation, these plastics are in that to melt extrude the temperature that adds man-hour low, the screw rod that extrusion equipment is adopted, spiral shell thorax, head, core rod, die sleeve etc. are less demanding, easily electric wire are processed into belt-like form.Fluoroplastic insulated tape cable then adopts perfluoroethylene-propylene (FEP), polytetrafluoroethylene (PTFE) and Meltability polytetrafluorethyletubular fluoroplastics (hereinafter to be referred as fluoroplastics) such as (PFA) to do the insulation layer material, fluoroplastic insulated tape cable is applicable to the electric equipment that fixedly lays and the connection of instrument circuit, has high-low temperature resistant, humidity, chemical resistance corrosion, light and tough and characteristics such as volume is little, compact conformation.But because fluoroplastics all have very high requirement to equipment, mould, technology controlling and process etc. when high temperature is extruded.So, up to the present, still do not have the fluoroplastic insulation flat cable on the market and occur.
Summary of the invention
The purpose of this invention is to provide a kind of fluoroplastic insulated tape cable, to solve the problem of the desired high-low temperature resistant of connection that traditional flat cable can't satisfy electric equipment and instrument circuit, humidity, chemical resistance corrosion.
In order to achieve the above object, the technical solution adopted in the present invention:
Fluoroplastic insulated tape cable includes sheath, it is characterized in that: also include many conductor wire cores side by side, every conductor wire core outsourcing is covered with insulating barrier, and described insulating barrier outsourcing is covered with flat sheath, and described insulating layer material adopts fluoroplastics.
Described fluoroplastic insulated tape cable is characterized in that: the radical of described conductor wire core is 2～9.
Described fluoroplastic insulated tape cable is characterized in that: described conductor wire core is formed by many copper cash layer-strandings.
The present invention is simple in structure, adopts fluoroplastics as insulating layer material, has high-low temperature resistant, humidity, chemical resistance corrosion, light and tough and characteristics such as volume is little, compact conformation.

Structural representation when Fig. 3 is nine for conductor wire core radical of the present invention.
Embodiment
Fluoroplastic insulated tape cable, include sheath 1, also include many conductor wire cores 2 side by side, the radical of conductor wire core 2 is 2～9, conductor wire core 2 is formed by many copper cash layer-strandings, every conductor wire core 2 outsourcings are covered with insulating barrier 3, and insulating barrier 3 outsourcings are covered with flat sheath 1, and insulating barrier 3 materials adopt fluoroplastics.
Fluoroplastics always have some fluoro-gas and decompose when high temperature is extruded, these analytes have strong corrosiveness to the common metal material, so the screw rod that adopts when fluoroplastics are extruded, spiral shell thorax, head, core rod, die sleeve etc. all will adopt the nickel-base alloy steel of high nickel content to make, to avoid the generation of heavy corrosion phenomenon, guarantee the quality of extruded product.And the difficulty of processing of nickel-base alloy steel when making mould is big, will be from many-sided consideration such as macromolecule, mechanics, materialogy processing technology, though look fairly simple on the product structure, if but do not note, multiple situations such as the variation of conductor twisting pitch, variation in diameter, sheath surface coarsening take place easily and cause cable of low quality.To adopt the lead of different-diameter to be twisted into conductor in the processing earlier as required, or adopt solid conductor as conductor; Adopt again to melt extrude, the electric wire of fluoroplastic insulation is made belt-like form.
Because the especially thinner monofilament copper cash of monofilament copper cash is in stranded process, the size of stranded tension force is difficult to control, be easy to cause diameter less than normal the heart yearn drawing-down, the mechanical and physical performance indexs such as external diameter, D.C. resistance of electric wire can not be satisfied use and technological requirement; If multicore inner wire irregular arrangement, then can make and extrude external diameter is not problem such as rounding very.To this, take to carry out under the regular stranded situation to multi-core conductor, adopt new design, reasonably conductor or core are arranged, multilayer is stranded, makes conductor or core cylindrical rule neat, the neat purpose of rule is extruded in final realization, note controlling well tension force simultaneously, prevent that conductor from attenuating, and influences electric property.
The quality of the design of extrusion die and processing quality decision flat cable.To this, we have taked to acquire or improve present extrusion equipment and mould.In mold design, that understands earlier the F40 material joins mode coefficient and draw ratio, and in conjunction with the influence of shearing force to melt, and the relation of shear rate and take-up speed designs again, and mould adopts and squeezes tubular type.Screw rod, spiral shell thorax, head, mould all adopt the nickel-base alloy steel to make.The final condition of molding that adopts is as follows: screw diameter: 30mm, and draw ratio: 22, compression ratio: 2.6, body temperature: first section: 240 ℃, second section: 270 ℃, the 3rd section: 295 ℃, mold temperature: 350～360 ℃.
The ambient temperature that the present invention is suitable for
*Be-55 ℃～200 ℃, the temperature rise when the ambient temperature here comprises cable work.Relative humidity is for when ambient temperature is 40 ℃, and relative humidity reaches 98%.
