Abstract

The utility model discloses a fiber winding control line, and relates to the technical field of a cable. The fiber winding control line comprises a line core beam which comprises insulating line cores. The external part of the line core beam is wrapped with a PET tape winding layer (4), a shielding layer (5) and a sheath layer (6). The fiber winding control line is characterized in that: each insulating line core comprises a conductive line core (1), of which the surface is wound with a fiber winding layer (2). The surface of the fiber winding layer (2) is wrapped with an insulating layer (3). The beneficial effects of the utility model reside in that: The external part of a single-core conductor line core is firstly wrapped with a layer of fibers, and then extruded with polyvinyl chloride plastic acting as the insulating layer so that insulation resistance of the cable is effectively enhanced and mechanical strength of the cable is enhanced. Therefore, the cable is high in insulation resistance, great in heat resistance performance and high in shielding performance. The external part of the line core beam is wrapped with the PET tape, and then is weaved with the metal shielding layer. The external surface of the shielding layer is extruded with the polyvinyl chloride outer sheath so that flexibility of the cable is enhanced to a greater degree.

Description

The wrapped control line of fiber

Technical field

The utility model relates to the cable technology field, particularly a kind of equipment control cables.

Background technology

Along with the development of electromagnetic wire industry and the maturation in market, China's lapped wire is towards the future development of variation and high efficiency, and the demand of novel lapped wire is increasing.Lapped wire is used cotton yarn and silk in early days, be called for cotton covered wire and silk-covered wire, once for motor, electrical equipment, its insulation thickness is large, thermal endurance is low, and only outside conductor wire core, wrapped one deck filament is as insulation, and the insulation resistance of electric wire is low, performance is stable not, especially needs to be applied to generator, transformer, high-voltage motor, electric motor of automobile etc. and need to optimize the existing cable structure to the control cables in the extra high main equipment of reliability requirement.

The utility model content

The purpose of this utility model is: for problems of the prior art, by optimizing the construction of cable, selecting new material, employing is wrapped filament outside conductive cable cores, and extrude the methods such as polyvinyl chloride insulation and sheath outside it, provide a kind of and had that the good electrical performance is good, good heat resistance, the wrapped control line of the fiber that tensile strength is higher, shielding is good.Can be widely used as the control connection line in large-scale machinery equipment.

The purpose of this utility model realizes by following technical proposals: the wrapped control line of fiber, comprise the core bundle, the core bundle comprises that insulated wire cores, core bundle outer cladding PET band lapping layer, screen, restrictive coating, insulated wire cores is by conductor wire core, the conductor wire core surface is wound around fiber lapping layer, fiber lapping layer surface coverage insulating barrier.

Further, insulating layer material is polyvinyl chloride.

Further, PET is the braiding shape with the screen of lapping layer appearance.

Further, insulated wire cores is 2 ~ 20.

The beneficial effects of the utility model:

(1) the utility model adopts the construction of cable of optimizing.Single core conductor core surface is wrapped one deck filament first, extrude again igelite as insulating barrier, effectively improved the insulation resistance of cable, make that cable machinery intensity is high, insulation resistance is large, good heat resistance, shielding properties are strong, meet the needs that the device transmission control signal is used.

(2) will thoroughly do away with after the wrapped PET of edge core stranding band braided metal screen again, the screen outer surface extrudes the polyvinyl chloride oversheath, has improved largely the softness of cable more.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, 1 is conductor wire core, and 2 is the fiber lapping layer, and 3 is insulating barrier, and 4 is PET band lapping layer, and 5 is screen, and 6 is restrictive coating.

Embodiment

Below in conjunction with specific embodiments and the drawings, the utility model is further described.

Embodiment: as shown in Figure 1, the wrapped control line of fiber comprises that conductor wire core 1, fiber lapping layer 2, insulating barrier 3, PET are with lapping layer 4, screen 5 and restrictive coating 6.Form fiber lapping layer 2 at the surperficial wrapped one deck filament of single core conductor wire core 1, extrude again the insulation of one deck igelite in fiber lapping layer 2 outsides, form insulating barrier 3, form so single insulated wire cores, effectively improved the insulation resistance of cable, make that cable machinery intensity is high, insulation resistance is large, good heat resistance, shielding properties are strong.The edge core proper alignment of thoroughly doing away with form the core bundle more, insulated wire cores is 2 ~ 20, and PET band lapping layer 4 is at the wrapped PET band of core bundle outer surface, after wrapped PET band, forms cable core, braided metal screen 5 outside cable core again, metal screen layer 5 is between PET band lapping layer 4 and restrictive coating 6.Screen 5 can avoid external electromagnetic field to exert an influence to cable core.Extrude the polyvinyl chloride oversheath at metal screen layer 5 outer surfaces, form restrictive coating 6, improved largely the softness of cable.The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
