Abstract
The invention discloses an anti-stretching coaxial cable which comprises a solid copper conductor located at the center of the coaxial cable, a first insulating layer arranged outside the solid copper conductor in a sleeved mode, a net-shaped conducting layer arranged outside the first insulating layer in a sleeved mode, multiple first reinforcing parts which are evenly distributed between the first insulating layer and the net-shaped conducting layer and a second insulating layer. The gaps among the first reinforcing parts are filled with first buffering materials. The second insulating layer is arranged outside the net-shaped conducting layer in a sleeved mode. According to the anti-stretching coaxial cable, as multiple reinforcing parts are arranged between the net-shaped conducting layer and the solid copper conductor, the cable is prevented from being damaged in the stretching process.
Description
Technical field
The present invention relates to coaxial cable technology field, relate in particular to a kind of stretch-proof coaxial cable.
Background technology
Coaxial cable has referred to two concentric conductors, and conductor and screen share the cable in same axle center.The copper conductors that modal coaxial cable is isolated by insulating material forms, and in the outside of nexine insulating material, is another layer of ring shaped conductor and insulator thereof, and then whole cable is encased by the sheath of polyvinyl chloride or special teflon material.The electromagnetic field of coaxial cable is enclosed between internal and external conductor, therefore radiation loss is little, affected by external interference little, is usually used in transmitting multiplex telephony and TV.Yet coaxial cable is used in some cases, require it to there is bending resistance and stretch-resistance, for example, at automation field, coaxial cable, owing to shaking with parts, often there will be the phenomenon of bending; And when coaxial cable is bent or be stretched, may produce wearing and tearing to heart yearn, or cause heart yearn distortion, electric current or signal transmission quality are impacted.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of stretch-proof coaxial cable, avoid the damage of stretching to cable, and the impact on electric current or signal transmission quality.
A kind of stretch-proof coaxial cable that the present invention proposes, comprising:
Solid copper wire, is positioned at coaxial cable center;
The first insulating barrier, is sheathed on outside described solid copper wire;
Netted conductive layer, is sheathed on outside described the first insulating barrier;
A plurality of the first strengthening parts, are evenly distributed between the first insulating barrier and netted conductive layer, vacant first padded coaming that has been partially filled between a plurality of the first strengthening parts;
The second insulating barrier, is sheathed on outside netted conductive layer.
Preferably, the first insulating barrier outer wall to the distance between netted conductive layer inwall is mated with the first strengthening part diameter.
Preferably, on the equally distributed circumference of the first strengthening part or be evenly distributed on multilayer circumference.
Preferably, a plurality of the second strengthening parts are evenly set between the second insulating barrier and netted conductive layer, vacant second padded coaming that has been partially filled between a plurality of the second strengthening parts.
Preferably, the second insulating barrier outer wall to the distance between netted conductive layer inwall is mated with the second strengthening part diameter.
Preferably, on the equally distributed circumference of the second strengthening part or be evenly distributed on multilayer circumference.
Preferably, also comprise watertight composition, be located at the second insulating barrier outer wall.
In the present invention, owing to thering are a plurality of strengthening parts between netted conductive layer and solid copper wire, can avoid cable to damage in drawing process.

Embodiment
The embodiment of the present invention 1 has proposed a kind of stretch-proof cable, as shown in Figure 1, comprising: solid copper wire 1, is positioned at coaxial cable center; The first insulating barrier 2, is sheathed on outside described solid copper wire 1; Netted conductive layer 3, is sheathed on outside described the first insulating barrier 2; A plurality of the first strengthening parts 4, are evenly distributed between the first insulating barrier 2 and netted conductive layer 3, and the cross section of the first strengthening part 4 can be circular, ellipse, rectangle or other shape; Vacant first padded coaming 5 that has been partially filled between the first strengthening part 4, such as asbestos material etc., to avoid the mutual friction of heart yearn phase to produce loss; Strengthening part preferably evenly arranges, and for example, on equally distributed circumference, or is evenly distributed on multilayer circumference; The second insulating barrier 6, is sheathed on outside netted conductive layer 3, for example the exhausted layer of polyvinyl chloride or elastic polyurethane layer.
In the embodiment of the present invention 2, outside the second insulating barrier 6, be provided with watertight composition 7, as shown in Figure 2, avoid the water in environment to enter coaxial cable core wire and produce corrosion from outer wall.
In the embodiment of the present invention 3, a plurality of the second strengthening parts 8 are evenly set between the second insulating barrier 6 and netted conductive layer 3, as shown in Figure 3, vacant second padded coaming 9 that has been partially filled between the second strengthening part 8.
In the embodiment of the present invention 4, the distance between the second insulating barrier 6 and netted conductive layer 3 is mated with the second strengthening part 8 diameters, makes the second insulating barrier, netted conductive layer and the second strengthening part close-packed arrays, to improve the external force resistance intensity of cable.
In the embodiment of the present invention 5, the distance between the first insulating barrier 2 and netted conductive layer 3 is mated with the first strengthening part 4 diameters, makes the second insulating barrier, netted conductive layer and the first strengthening part close-packed arrays, to improve the external force resistance intensity of cable.
In the present invention, owing to thering are a plurality of strengthening parts between netted conductive layer and solid copper wire, can avoid cable to damage in drawing process.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
