Abstract
The utility model disclose a high-shielding coaxial cable which comprises an inner conductor, an insulation layer, a first aluminium foil shielding layer, a second aluminium foil shielding layer, a first braiding layer, a second braiding layer, a jacket inner layer and a jacket outer layer, wherein the inner conductor, the insulation layer, the second aluminium foil shielding layer, the second braiding layer, the jacket inner layer, the first aluminium foil shielding layer, the first braiding layer and the jacket outer layer are connected in sequence from inside to outside. The high-shielding coaxial cable has strong anti-interference performance, is very stable in signal transmission, and has very clear transmitted image.
Description
Technical field
The utility model relates to a kind of coaxial cable, particularly relates to a kind of high shielding coaxial cable.
Background technology
At present, the structure of most of coaxial video lines comprises four parts of inner wire, insulating barrier, braid, restrictive coating that set gradually from the inside to the outside.When the stronger occasion of electromagnetic wave was used, the interference free performance of the coaxial cable of this structure was relatively poor, receives the interference of extraneous signals such as electromagnetic wave easily, so the signal transmission is very unstable, and image transmitted is also very unintelligible.
The utility model content
The technical problem that the utility model will solve provides a kind of high shielding coaxial cable, and interference free performance is stronger.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of high shielding coaxial cable comprises inner wire, insulating barrier,
Also comprise first foil shielding layer, second foil shielding layer, first braid, second braid, sheath internal layer, sheath skin,
Said inner wire, insulating barrier, second foil shielding layer, second braid, sheath internal layer, first foil shielding layer, first braid, sheath skin connect from the inside to the outside successively.
Preferably, said first braid of the utility model, second braid are copper wire mesh braided layer.
Preferably, the said sheath internal layer of the utility model is the pvc sheath internal layer, and said sheath skin is that pvc sheath is outer.
Therefore compared with prior art, the utility model has following beneficial effect:
The shielding of aluminium foil is fine, and interference free performance is stronger, and is more outer by first foil shielding layer that aluminum foil material is processed; Can be used as the first road barrier of shielding external disturbances, second foil shielding layer is more inner, can be used as the second road barrier; Further shield external disturbances; Strengthened the interference free performance of whole cable greatly, the signal transmission is highly stable, and image transmitted is also very clear.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Be illustrated in figure 1 as the embodiment of the described a kind of high shielding coaxial cable of the utility model; Comprise inner wire 1, insulating barrier 2; Comprise that also first foil shielding layer 6, second foil shielding layer 3, first braid 7, second braid 4, sheath internal layer 5, sheath are outer 8, inner wire 1, insulating barrier 2, second foil shielding layer 3, second braid 4, sheath internal layer 5, first foil shielding layer 6, first braid 7, sheath outer 8 connect from the inside to the outside successively.
Wherein, sheath internal layer 5 can separate second braid 4 and first foil shielding layer 6, avoids second braid 4 and first foil shielding layer 6 to be in contact with one another and weares and teares.
Preferably, in the present embodiment, first braid 7, second braid 4 are copper wire mesh braided layer, and the braid of being processed by copper mesh also can play certain shielding action except can be used as outer conductor, further improve the interference free performance of whole cable.
Preferably; In the present embodiment, sheath internal layer 5 is the pvc sheath internal layer, and sheath outer 8 is that pvc sheath is outer; The sheath internal layer of being processed by pvc material 5 can play the certain protection effect to cable inside with sheath outer 8, effectively prolongs the useful life of cable.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (3)
1. a high shielding coaxial cable comprises inner wire, insulating barrier, it is characterized in that:
