Description
Technical field
A kind of efficient coaxial cable is the utility model is related to, belongs to technical field of communication equipment.
Background technology
Ultrathin coaxial cable generally refers to control the external diameter of cable in Min., while flexibility, bending characteristic
The coaxial cable being improved.With the miniaturization of notebook computer, thin type, the high-definition and mobile phone of liquid crystal display
High performance, the wiring of increasingly desirable connection liquid crystal display must save space, improve bending reliability, anti-interference and
The characteristics such as wideband transmission, also reduce cost, and this, which just gives, not only saves space, transmission reliability but also the offer of high Ultrathin coaxial cable
The wide market space.
But many coaxial cables are due to unreasonable, the unqualified and production work of materials'use of structure design at present
The defects of skill etc., used under long-term work or rugged environment, it is difficult to which guarantee continues higher mechanical strength, and stable electricity is absolutely
Edge performance and permanent efficient capability of electromagnetic shielding.
Utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and providing one kind has certain machine
Tool intensity, while the efficient coaxial cable that shield effectiveness is good, fire resistance is good, simple in construction.
The technical scheme in the invention for solving the above technical problem is：A kind of efficient coaxial cable, including inner wire,
Insulating barrier, screen layer and restrictive coating, uniform some spaces on the insulating barrier；The screen layer is that fine copper silk screen and PET film are answered
Close screen layer；It is additionally provided between the screen layer and restrictive coating and singly leads aluminum foil mylar belt layer, the aluminum foil mylar belt layer of singly leading
Conduction one is facing to screen layer.
The space being uniformly arranged on the insulating layer, one layer can be formed and special be combined into one with dielectric and air
Insulating barrier, the dielectric constant of insulating barrier is reduced, so as to reduce the decay of signal transmission, directly enhance the transmission work(of cable
Rate.Secondly as the setting in space, reduces the usage amount of insulating layer material, has saved cost, reduce weight.Wire
The screen layer that net and PET film composite construction are formed, while ensure that cable has higher shield effectiveness, woven wire increases
Certain mechanical strength is added so that cable is more easy to keep shape.The laminated conduction of aluminum foil mylar belt is singly led, another side insulate,
With excellent electric conductivity, electric discharge magnetic disturbance and fire-retardant performance.Insulating barrier with space, answered by woven wire and PET film
Close the screen layer formed, singly lead aluminum foil mylar belt layer three cooperation, form triple effect shield effectiveness so that the signal transmission of cable
Efficiency is guaranteed.
Further, the shielding thickness 0.5mm.
Further, described singly lead is additionally provided with messenger wire between aluminum foil mylar belt layer and restrictive coating.Messenger wire can be used as ground wire
Use so that cable has stronger anti-lightning effect, improves the security that cable uses.
Further, the messenger wire is Copper covered steel material.
Further, the restrictive coating is made up of poly- perfluoroalkoxy resin.
The utility model compared with prior art, has advantages below and effect：The utility model passes through with space
Insulating barrier, the screen layer being compounded to form from woven wire and PET film, singly lead with aluminum foil mylar belt layer three, form triple effect
Shield effectiveness so that the effectiveness of cable is guaranteed；It is good mechanical property, simple in construction and with certain fire-retardant
Property.
Brief description of the drawings
Fig. 1 is the utility model cross section structure schematic diagram.
In accompanying drawing：1 is inner wire, and 2 be insulating barrier, and 3 be screen layer, and 4 is singly lead aluminum foil mylar belt layer, and 5 be restrictive coating, 6
For messenger wire.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, and following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Referring to Fig. 1, the present embodiment includes inner wire 1, insulating barrier 2, screen layer 3, singly leads aluminum foil mylar belt layer 4 and restrictive coating
5。
Insulating barrier 2 is coated on outside inner wire 1 with one heart by being made up of polytetrafluoroethylene (PTFE).It is evenly provided with insulating barrier 2 vertical
To continuously distributed space, the special insulating layer 2 that dielectric is harmonious with air is formed, had both improved the efficiency of transmission of cable, together
When reduce cost and own wt.
Screen layer 3 is the fine copper silk screen and PET film composite shielding layer 3 that thickness is 0.5mm, is coated on outside insulating barrier 2, shape
Into visible transparent electro-magnetic screen layer 3, there is fabulous shield effectiveness, its microwave attenuation is 25-46dB.
It is conductive singly to lead the one side of aluminum foil mylar belt layer 4, another side insulation, have excellent electric conductivity, electric discharge magnetic disturbance and
Fire-retardant performance, wherein conductive one is set facing to screen layer 3, it is coated on outside screen layer 3.
Singly lead and messenger wire 6 is additionally provided between aluminum foil mylar belt layer 4 and restrictive coating 5.Messenger wire 6 is made up of Copper covered steel material, can make
Used for ground wire so that cable has stronger anti-lightning effect.
Restrictive coating 5 is made up of poly- perfluoroalkoxy resin, is coated on the outside for singly leading aluminum foil mylar belt layer 4 and messenger wire 6.
Although the utility model is disclosed as above with embodiment, it is not limited to protection model of the present utility model
Enclose, any technical staff for being familiar with this technology, do not departing from the change made in spirit and scope of the present utility model and profit
