Description
Technical field
The utility model relates to field of cables, and especially a kind of have the function of transmission line and antenna duplicate transmissions and the parallel bunched cable of sewing developed according to leaky coaxial cable.
Background technology
Leaky cable had both had the signal transmitting effect, had antenna function again.By insulation outer rim orientation is opened the system leak, strengthen the space field intensity that needs emphasis detection space, with realization the guard key space is implemented accurately, monitored reliably.Along with development of science and technology, people are progressively improving for the safety precaution product requirement in important place, safety-protection system as important places such as military base, fortress, border, government bodies, police and judicial, prisons not only will give the alarm to intrusion behavior, also needs intrusion behavior is analyzed, judged.Sensitivity is low when the employed single leaky coaxial cable of these occasions is surveyed for intrusion behavior at present, comprehensively survey easy wrong report, and complexity is installed, laid, debugs to cable, can not satisfy higher requirement, therefore develop a kind of novel cable that can satisfy the instructions for use of above-mentioned field fully and be very important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of can survey and take precautions against specific emphasis orientation, the detectivity height, and rate of false alarm is low, Installation and Debugging are simple and convenient, can satisfy the parallel bunched cable of sewing of important events instructions for use fully.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of parallel bunched cable of sewing, constitute by insulated wire cores, screen and restrictive coating, the insulated wire cores outside is wrapped up screen and restrictive coating successively, insulated wire cores is made of inner wire and its outer insulating barrier of parcel, it is characterized in that: the insulated wire cores of being wrapped up in the screen is two that are arranged side by side, the plastic-aluminum combined rete of self-adhesion polyester that an orientation is opened the system leak is all wrapped up in each insulated wire cores outside, and these two made leaks of the plastic-aluminum combined rete of insulated wire cores self-adhesion polyester are opposing setting.
And, between described two insulated wire cores two gauze screens are set vertically, separate with semi-conductive layer in the middle of these two gauze screens.
And the insulating barrier of described insulated wire cores adopts skin-bubble-Pi three-layer insulated, and the center froth bed is a nitrogen inflation physical blowing polyethylene layer.
And the screen that described two insulated wire cores outside is wrapped up is made up of the gauze screen that vertically is provided with between the plastic-aluminum combined rete of the self-adhesion of insulated wire cores outer wrapping, two insulated wire cores and semiconductive shielding layer three parts of two common parcels in the insulated wire cores outside.
And described restrictive coating is fast light hot polymerization ethene restrictive coating.
Advantage of the present utility model and beneficial effect are:
1, two parallel leaky coaxial cable boundlings of this cable employing are one, because it opens the system leak in insulation outer rim orientation, therefore orientable to the space leakage signal, can implement to survey accurately, monitor to the guard key place, solved single leaky cable owing to its comprehensive radiation signal, the problem of low, the easy generation wrong report of detectivity.
2, the insulating barrier of this cable adopts skin-bubble-Pi physically foamed pe insulation, its center froth bed is a nitrogen inflation physical blowing polyethylene, therefore cable has characteristics such as low decay, low-loss, but transmitting high-frequency signal, realization is carried out intelligent decision to different objects such as animal, personnel, vehicles, confirms invasion or intention and the trend passed by; Its endodermis and exodermis have waterproof ability and certain physical intensity are arranged, and are applicable to underground laying.
3, the shielding action of this cable is mainly finished by three parts: at first, the plastic-aluminum combined rete of self-adhesion polyester with directed leak that the insulated wire cores outside is wrapped up can guarantee the site space signal abundance that the need emphasis detects, the spatial field strong stability; Secondly, the gauze screen that institute vertically is provided with between two insulated wire cores can reduce two interference and interference from outside signals that cable is mutual, the reliability behind the assurance cable boundling effectively; At last, adopt and extrude semiconductive shielding layer, can make insulated wire cores Electric Field Distribution on every side even, and can stop the interference of extraneous spacing wave.
4, this cable adopts the boundling form, cable is installed, laid, debug simplification, greatly reduces cost.
5, this cable adopts and buries installation underground, therefore is difficult for invaded person and finds and destroy, thereby played well and effectively supervisory function bit.
6, the restrictive coating of this cable adopts fast light hot polymerization vinyl material to make, so cable is good from heavy and light, moisture resistance, can be embedded in the open air for a long time.
7, the placement of can only tiling of the profile side of the employing flat pattern of this cable, cable can guarantee the stability of signal radiation and is convenient to install.
8, the utility model is a kind of safety-protection system private cable that is formed by two skin foam skin physical foam insulation leaky coaxial cable boundlings, it can be in conjunction with digital technology, high frequency technique and the computer technology realization intelligent decision to different objects, the intention of analyzing invasion or passing by, realize the intelligence warning, therefore can be widely used in important places such as military base, prison, museum, power station, government bodies and police and judicial.
