Abstract
The invention relates to a signal cable. The signal cable comprises a protection layer, a protection sleeve and a plurality of cables, wherein the protection sleeve is arranged on the outer side of the protection layer; the protection layer comprises insulation layers, a wave absorbing layer and a shielding layer; the insulation layers are arranged on two sides of the cables; a tensile material layer covers the wave absorbing layer; the wave absorbing layer is arranged between the insulation layer and the shielding layer; and the protection sleeve is cylindrical and covers the external part of the protection layer. The signal cable absorbs electromagnetic waves by using a wave absorbing material layer on the wave absorbing layer, eliminates the electromagnetic waves reflected to and fro in a shielding cavity, reduces electromagnetic radiation interference, has a good shielding effect and high electromagnetic compatibility, and is safe and practical; the protection sleeve covers the external part of the signal cable; and the signal cable is safe and environment-friendly.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of signal cable.
Background technology
In order to block the harassing and wrecking in external interference source, perhaps prevent other equipment of electromagnetic interference of transmission signals in the transfer of data, the blue general employing of holding wire adds measures such as aluminium foil, Aluminum-plastic composite bag, metal knitted net electromagnetic interference is shielded.Yet, development along with mechanics of communication, the speed of transfer of data is more and more faster, the frequency of transmission is more and more higher, the irradiation of electromagnetic waves amount also increases thereupon, in the field of data transmission of high frequency, hyperfrequency, traditional shielding material such as aluminium foil, Aluminum-plastic composite bag, metal knitted net etc. have not reached desirable shield effectiveness, can't satisfy the requirement of Electro Magnetic Compatibility.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and strengthen electromagnetic shielding, weaken interference, good looking appearance, safe effect is good, practicality is good signal cable.
In order to overcome the defective that exists in the background technology; the technical solution adopted for the present invention to solve the technical problems is: a kind of signal cable; comprise protective layer, protective sleeve and some cables; described protective sleeve is arranged on the protective layer outside; described protective layer comprises insulating barrier, inhales ripple layer and shielding layer; described insulating barrier is arranged at the both sides of cable; be coated with the tensile material bed of material on the described suction ripple layer; described suction ripple layer is arranged between insulating barrier and the shielding layer; described protective sleeve is the cylinder protective sleeve, and described protective sleeve is coated on the protective layer outside.
According to another embodiment of the invention, a kind of signal cable comprises that further described shielding layer is netted litzendraht wire.
According to another embodiment of the invention, a kind of signal cable comprises that further described shielding layer is a wire sheathing.
According to another embodiment of the invention, a kind of signal cable comprises that further described absorbing material layer thickness is 0.015-0.15mm.
According to another embodiment of the invention, a kind of signal cable comprises that further described insulating barrier is an insulation film.
The invention solves the defective that exists in the background technology, its advantage is: utilize the absorbing material layer of inhaling on the ripple layer to absorb electromagnetic wave, eliminate the electromagnetic wave that comes back reflective in the shielding cavity, reduce electromagnetic interference, shield effectiveness is good, and Electro Magnetic Compatibility is good, and is safe and practical.

In addition, described shielding layer 4 is netted litzendraht wire.
In addition, described shielding layer 4 is a wire sheathing, and screen has been strengthened shielding action, to eliminate electromagnetic interference.
In addition, described suction ripple layer 3 thickness are 0.015-0.15mm.
In addition, described insulating barrier 2 is an insulation film.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
