Abstract
The invention discloses a coaxial cable which comprises a central conductor, an insulating layer arranged outside the central conductor, an inner shield layer arranged outside the insulating layer, a reticular conductive layer arranged outside the inner shield layer, a first mica tape layer arranged outside the reticular conductive layer, an outer shield layer arranged outside the first mica tape layer, a second mica tape layer arranged outside the outer shield layer, and an outer sheath layer arranged outside the second mica tape layer. With the adoption of the mode, the coaxial cable has good shielding and anti-interference performance and fire resistance.
Description
Technical field
The present invention relates to cable technology field, particularly relate to a kind of coaxial cable.
Background technology
Coaxial cable is in cable, to use commonplace a kind of cable, is mainly used in transmitting in wireless telecommunications, public TV antenna, broadcast, closed monitor system, high-frequency and relevant electronic equipment radio frequency (video) signal.
Existing coaxial cable requires further improvement in shielding properties and fire-resistant fire protecting performance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of coaxial cable, has good shielding interference free performance and fire-resistant fire protecting performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of coaxial cable is provided, comprises: center conductor, be arranged on described center conductor outside insulating barrier, be arranged on described insulating barrier outside internal shield, be arranged on described internal shield outside netted conductive layer, be arranged on described netted conductive layer outside the first mica belt, be arranged on described the first mica belt outside outer shielding layer, be arranged on the second mica belt of described outer shielding layer outside and be arranged on the external sheath layer of described the second mica belt outside.
In a preferred embodiment of the present invention, described the first mica belt adopts synthetic mica tape, and described the second mica belt adopts gold mica tape.
In a preferred embodiment of the present invention, described internal shield and outer shielding layer are foil shielding layer.
In a preferred embodiment of the present invention, described external sheath layer is PVC oversheath.
The invention has the beneficial effects as follows: coaxial cable of the present invention, has good shielding interference free performance and fire-resistant fire protecting performance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of coaxial cable one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, center conductor, 2, insulating barrier, 3, internal shield, 4, netted conductive layer, the 5, first mica belt, 6, outer shielding layer, the 7, second mica belt, 8, external sheath layer.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A coaxial cable, comprising: center conductor 1, be arranged on described center conductor 1 outside insulating barrier 2, be arranged on described insulating barrier 2 outsides internal shield 3, be arranged on described internal shield 3 outsides netted conductive layer 4, be arranged on described netted conductive layer 4 outsides the first mica belt 5, be arranged on described the first mica belt 5 outsides outer shielding layer 6, be arranged on the second mica belt 7 of described outer shielding layer 6 outsides and be arranged on the external sheath layer 8 of described the second mica belt 7 outsides.
Preferably, described internal shield 3 and outer shielding layer 6 are foil shielding layer, by both combinations, have effectively strengthened the shielding interference free performance of coaxial cable of the present invention, have fully met the high request of coaxial cable.
Preferably, described the first mica belt 5 adopts synthetic mica tape, described the second mica belt 7 adopts gold mica tape, when running into the condition of a fire, first the first mica belt 5 can protect cable to continue to use a period of time, after the first mica belt 5 is destroyed, the second mica belt 7 can continue to protect cable, has greatly strengthened fire-resistant fire protecting performance of the present invention; In addition, synthetic mica tape performance is good but expensive, and gold mica tape performance is general but cheap, uses both combinations, when strengthening fire resistance, can significantly not increase cost again, practical.
Preferably, described external sheath layer 8 is PVC oversheath.
Coaxial cable of the present invention, has good shielding interference free performance and fire-resistant fire protecting performance.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
