The utility model content
The technical problem that the utility model will solve is, and defective that resistance to elevated temperatures relatively poor little to through-put power in the prior art provides a kind of high-power bellows radio frequency coaxial-cable.
The utility model solves the technical scheme that its technical problem adopted: a kind of high-power bellows radio frequency coaxial-cable is provided, comprises the insulator of coaxial inner wire, the said inner wire of coating, the sheath that pressure is embedded in the wrinkle copper pipe outer conductor on the said insulator and coats said outer conductor from inside to outside successively; Wherein said insulator comprises the adhesive phase that is coated on the said inner wire, the crosslinked foaming polyolefin insulation layer that coats said adhesive phase and the smooth layer that coats said crosslinked foaming polyolefin insulation layer from inside to outside successively; Said bellows outer conductor is pressed and is embedded on the said smooth layer.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said adhesive phase is the ethylene acrylic acid co polymer adhesive phase.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said smooth layer is the polyethylene smooth layer.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said inner wire is the silver-coated copper wire inner wire.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said inner wire is silver-plated copper-clad aluminum conductor inner wire.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said sheath is a polyolefin jacket.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said sheath is a polypropylene cover.
In the high-power bellows radio frequency coaxial-cable according to the utility model embodiment, said sheath is the low smoke and zero halogen sheath.
The utility model; Have following beneficial effect: because of in the high-power bellows radio frequency coaxial-cable of the utility model embodiment, insulator comprises the adhesive phase that is coated on the said inner wire, the crosslinked foaming polyolefin insulation layer that coats said adhesive phase and the smooth layer that coats said crosslinked foaming polyolefin insulation layer from inside to outside successively; Said bellows outer conductor is pressed and is embedded on the said smooth layer, so than normal cable, the through-put power of the cable in the utility model will improve 50%, high-temperature resistant temperature is increased to 105 ℃ from 85 ℃, more can be suitable for hot environment or long-term use.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the high-power bellows radio frequency coaxial-cable of the utility model embodiment;
Fig. 2 is the cutaway view of the insulator of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In the preferred embodiment of the utility model; As shown in Figure 1, a kind of high-power bellows radio frequency coaxial-cable comprises the wrinkle copper pipe outer conductor 300 of coaxial inner wire 100, the insulator 200 that coats inner wire 100, coated insulation body 200 and the sheath 400 that coats outer conductor 300 from inside to outside successively.Wherein wrinkle copper pipe outer conductor 300 constitutes one through external pressure and insulator 200.
Fig. 2 shows the cross-section structure according to the insulator 200 of the utility model embodiment; As shown in Figure 2, insulator 200 comprises the adhesive phase 210 that is coated on the inner wire 100, the crosslinked foaming polyolefin insulation layer 220 of coating and bonding agent layer and the smooth layer 230 that coats the crosslinked foaming polyolefin insulation layer from inside to outside successively.This moment, bellows outer conductor 300 pressures were embedded on the smooth layer 230.Wherein, adhesive phase 210 for example is ethylene acrylic acid co polymer (EAA) adhesive phase, can strengthen the adhesiveness between crosslinked foaming polyolefin insulation layer 220 and the inner wire 100, makes insulator 200 to be integrally formed better with inner wire 100.Smooth layer 230 for example is the polyethylene smooth layer, in order to reinforced insulation body 200 surface smooth degree, makes wrinkle copper pipe outer conductor 300 to be integral with insulator 200 is chimeric better.
