Abstract
The invention discloses an anti-bending 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 hollow pipes 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 hollow pipes 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-bending coaxial cable, as the hollow pipes are arranged between the net-shaped conducting layer and the solid copper conductor and the hollow pipes deform and absorb external force as the whole coaxial cable is bent under external force. After the external force disappears, the hollow pipes recover under the self elasticity and the smoothness and the straightness of the coaxial cable are ensured. In addition, the quality of current or signal transmission is not affected.
Description
Technical field
The present invention relates to coaxial cable field shaping technique, relate in particular to a kind of bend resistance 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 bend resistance coaxial cable, avoid the damage of stretching to cable, and the impact on electric current or signal transmission quality.
A kind of bend resistance 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 hollow pipes, 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 hollow pipes;
The second insulating barrier, is sheathed on outside netted conductive layer.
Preferably, the distance between the first insulating barrier and netted conductive layer inwall is mated with the first hollow pipe diameter.
Preferably, a plurality of the second hollow pipes 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 hollow pipes.
Preferably, the second insulating barrier outer wall to the distance between netted conductive layer inwall is mated with the second hollow pipe diameter.
Preferably, at the second insulating barrier outer wall, be provided with watertight composition.
In the present invention, owing to having a plurality of the first hollow pipes between netted conductive layer and solid copper wire, when whole coaxial cable is subject to external force bending, the first hollow pipe distortion, plays cushioning effect to external force; After external force disappears, the first hollow pipe recovers under self elastic reaction, has guaranteed the straight of coaxial cable, does not affect electric current or signal transmission quality.

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 hollow pipes 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 a plurality of the second hollow pipes 8.
In the embodiment of the present invention 4, the distance between the first insulating barrier 2 and netted conductive layer 3 inwalls is mated with the first hollow pipe 4 diameters, makes the first insulating barrier, netted conductive layer and the second hollow pipe close-packed arrays, to improve the external force resistance intensity of cable.
In the embodiment of the present invention 5, the distance between the second insulating barrier 6 and netted conductive layer 3 is mated with the second hollow pipe 8 diameters, makes the second insulating barrier, netted conductive layer and the second hollow pipe close-packed arrays, to improve the external force resistance intensity of cable.
In the present invention, owing to having a plurality of the first hollow pipes between netted conductive layer and solid copper wire, when whole coaxial cable is subject to external force bending, the first hollow pipe distortion, plays cushioning effect to external force; After external force disappears, the first hollow pipe recovers under self elastic reaction, has guaranteed the straight of coaxial cable, does not affect electric current or signal transmission quality.
