Abstract
The invention discloses a multifunctional transmission electronic cable comprising a non-conductive inner core. The outer layer of the inner core is provided with a cable inner core through stranding. The outer side of the cable inner core is provided with a PVC isolation insulating layer through extrusion. A plurality of arc-shaped grooves are uniformly separated and distributed on the outer circumferential surface of the inner core. The radian of each arc-shaped groove is 100 degrees. The cable inner core is located in the arc-shaped grooves. A plurality of arc-shaped grooves are uniformly separated and distributed on the inner circumferential wall of the PVC isolation insulating layer. The radian of each groove is 100 degrees. A signal shielding cover is arranged between every two arc-shaped grooves, and an outer shielding layer is arranged between every two grooves. The multifunctional transmission electronic cable of the invention can be used to increase the cable inner core diameter and improve the shielding performance.
Description
Technical field
The present invention relates to a kind of power transmission cable, be specifically related to a kind of multi-functional transmission of electricity electronic cable.
Background technology
The flexible cable of prior art, cable inner core for bundle system or bundle system after stranded forming again, cable inner core external diameter is little, bundle system and all have certain pitch when stranded, and pitch is less, makes whole cable bending property and the reduction of soft degree.Simultaneously, prior art power transmission cable, conventionally in the middle of, be directly cable inner core, in the time that alternating current passes through cable inner core, especially while making curtage conduct in cable inner core with the higher electronics of frequency, can produce kelvin effect, electric current will concentrate on cable core surface and flow through, be gathered in total cable inner core top layer, but not be evenly distributed in the sectional area of whole cable inner core.Adopt such design, cause the cable of the core of cable inner core often not have the effect of conduction, a kind of waste for the cable of core itself, and want to increase the ampacity of cable, must make the overstriking of cable inner core part, this is also increasing material cost and the weight of cable virtually.
Summary of the invention
Multi-functional transmission of electricity electronic cable, comprise nonconducting inner core, at the outer stranded cable inner core that has of inner core, be extruded with PVC isolated insulation outward at cable inner core, multiple arc grooves uniformly at intervals on the outer circumference surface of described inner core, the radian of arc groove is 100 degree, described cable inner core is arranged in arc groove, the groove of multiple arcs uniformly at intervals on the inner peripheral wall of described PVC isolated insulation, the radian of groove is 100 degree, arc groove is provided with signal shielding cover between two, and between groove, is equipped with outer shielding layer between two.
Adopt such scheme, multiple arc grooves uniformly at intervals on the outer circumference surface of described inner core, the radian of arc groove is 100 degree, the groove of multiple arcs uniformly at intervals on the inner peripheral wall of described PVC isolated insulation, described cable inner core is arranged in arc groove, the radian of groove is 100 degree, because cable inner core is by arc groove and groove sealing, the outside diameter of cable is not in the situation that increasing, can make the diameter of cable inner core increase, be beneficial to make and bear electric current more greatly and the weight little cable of increase relatively.Arc groove is provided with signal shielding cover between two, and between groove, is equipped with outer shielding layer between two.By outer shielding layer and signal shielding cover, can prevent that cable inner core from producing interference each other.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 miniature core courage, 1a is signal shielding cover, and 2 is cable inner core, and 3 is PVC isolated insulation, and 3a is outer shielding layer.
Embodiment
Multi-functional transmission of electricity electronic cable of the present invention, comprises nonconducting inner core 1, and inner core 1 is flexible plastics packing or rubber filling bar.Multiple arc grooves uniformly at intervals on the outer circumference surface of inner core 1, the radian of arc groove is 100 degree.Arc groove is provided with signal shielding cover 1a between two.Signal shielding cover is the screen of metal, and signal shielding cover is the screen that tin copper is done.There is a cable inner core 2 interior core outer surface is stranded, equal stranded cable inner core 2 in each arc groove.Be extruded with PVC isolated insulation 3 outward at cable inner core, the groove of multiple arcs uniformly at intervals on the inner peripheral wall of PVC isolated insulation 3, the radian of groove is 180 degree, and between groove, is equipped with between two outer shielding layer 3a.Outer shielding layer is the screen of metal.Outer shielding layer is the screen that adopts tin copper product to make.
