Abstract
A cable comprises a signal wire, an electrical power wire, an aluminum foil mylar layer, a metal braid layer and an oversheath. The signal wire and the electrical power wire are wrapped by the aluminum foil mylar layer, the aluminum foil mylar layer is wrapped by the metal braid layer, and the metal braid layer is wrapped by the oversheath. The cable also comprises a wave-absorbing plastic cement granular layer which is made with magnetic wave-absorbing material and plastic cement material and arranged between the metal braid layer and the oversheath. The wave-absorbing plastic cement granular layer can prevent the signal wire from external electromagnetic interference when signals are transmitted by the signal wire, thereby guaranteeing reliability of signal transmission and increasing pliability of the wire.
Description
[technical field]
The utility model relates to a kind of cable, refers to a kind of cable that is used for transmitting high-frequency signal especially.
[background technology]
Along with the development of electronics technology product is popularized, cable as a kind of instrument of transmission signals be widely used in electronic equipments such as household electrical appliances, instrument and meter, electric tool and automation equipment connection.Yet in signals transmission, especially in the high-frequency signal transmission process, cable very easily is subjected to the interference of external electromagnetic ripple signal, thereby thereby often need to adopt the design of cover magnet ring on cable to eliminate or reduce the interference of external electromagnetic field to absorb outside noise, this design is obvious to the noise effect that low-frequency range produces, but electromagnetic wave signal DeGrain to higher frequency band, the area that covers cable is little, thereby influence the reliability of signal transmission, and the processing procedure complexity of magnet ring, thickness is thicker, and it is big to take up room.
So, be necessary to provide a kind of and have stronger anti-electromagnetic interference performance, stable signal transmission and make simple novel cable.
[utility model content]
The purpose of this utility model is to provide a kind of cable that improves anti-electromagnetic interference performance.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of cable, it comprises that holding wire, power line, aluminium foil wheat draw layer, wire sheathing and oversheath, the aluminium foil wheat draws layer that holding wire and power line are coated in it, wire sheathing is coated on the aluminium foil wheat and draws outside the layer, oversheath is coated on outside the wire sheathing, and described cable also comprises mix the suction ripple plastic cement stratum granulosum that constitutes with plastic plastic material between wire sheathing and oversheath and by the magnetic absorbing material.
Compared to prior art, when making the signal wire transmits signal, suction ripple plastic cement stratum granulosum of the present utility model avoids the external electromagnetic wave interference, guarantee the reliability of signal transmission, improve the pliability of cable.
[description of drawings]
Fig. 1 is the viewgraph of cross-section of the utility model cable.
[embodiment]
Please refer to shown in Figure 1ly, cable 100 of the present utility model comprises that holding wire 5, two power lines 6, aluminium foil wheats draw layer 4, wire sheathing 3, magnetic plastic cement stratum granulosum 2 and oversheath 1.Holding wire 5 comprises two leads 51 and is positioned at outer field insulating barrier 52.Two power lines 6 are positioned at the both sides of holding wire 5.The aluminium foil wheat draws layer 4 to be coated on holding wire 5 and power line 4 outsides, and wire sheathing 3 is coated on the aluminium foil wheat and draws layer 4 outside with the shielding external electromagnetic waves.Magnetic plastic cement stratum granulosum 2 is to combine the micelle of making by the magnetic absorbing material with the plastic soft plastic cement, and it is coated on outside the wire sheathing 3 in the extrusion mode.Oversheath 1 is positioned at the internal structure of outermost layer with protection cable 100.
Compare with the magnet ring of prior art, magnetic plastic layer 2 is clad metal braid 3 fully, the magnetic absorbing material can absorb the electromagnetic wave of different frequency range, especially thereby frequency electromagnetic waves there is the electromagnetic wave that good assimilation effect can absorption signal line 5 outsides, then can reduces the coverage rate of wire sheathing 3, save cost, the plastic soft plastic cement makes the flexible enhancing of cable 100, Stability Analysis of Structures is cracky not, and the processing procedure of magnetic plastic layer 2 to compare magnet ring simple, it is little to take up room.
