Description

Conductive fabric shields encoder cable

Technical field

The utility model is related to field of cable technology more particularly to encoder cables.

Background technology

Current developed country and developing country all are endeavouring to accelerate " reindustrialization " and process of industrialization, with industry It continues to develop, the use of encoder is also more and more extensive, and encoder is to work out signal or data, be converted to and can be used to lead to The laser propagation effect of the equipment of the signal form of news, transimission and storage, the signal or data that how to improve cable becomes a needs The technical issues of continuously improving and solving.

Utility model content

In order to improve the signal of cable or the laser propagation effect of data, the utility model provides a kind of conductive fabric shielding coding Device cable.

The utility model technical solution used for the above purpose is：Conductive fabric shields encoder cable, insulation 2 outside of core wire is band 3, and 3 outside of band is conductive fabric 4, and 4 outside of conductive fabric is equipped with sheath 1.

Drain wire 5 is equipped between the conductive fabric 4 and band 3.

The conductor of the insulation core wire 2 is that oxygen-free copper is twisted copper wire.

The conductive fabric of the utility model shields encoder cable, as connection and control Special flexible cable, cable itself Structure and encoder high-resolution, run at high speed, the runnings requirement perfection knot such as cross-talk resistant, anti-interference and long distance transmission It closes, cable increases the electric conductivity of cable, flexibility and the performances such as resistant to bending using conductive fabric shielding.

Description of the drawings

Fig. 1 is the utility model conductive fabric shielding encoder construction of cable figure.

In figure：1, sheath, 2, insulation core wire, 3, band, 4, conductive fabric, 5, drain wire.

Specific implementation mode

The conductive fabric shielding encoder construction of cable of the utility model is as shown in Figure 1,2 outside of insulation core wire is band 3, packet 3 outside of band is conductive fabric 4, and 4 outside of conductive fabric is equipped with sheath 1, drain wire 5 is equipped between conductive fabric 4 and band 3.Two insulation Core wire 2 is twisted to form stranded core.

Insulation core wire 2 is twisted copper wire as conductor using super soft, high tenacity oxygen-free copper, so that the entirety of cable is had good Flexibility, the performances such as resistant to bending and signal transmission；Cable is internally provided with four groups of stranded cores.The insulation of insulation core wire 2 Part be high resiliency, high intensity, low-k elastomeric material, there is high conductivity, excellent chemical stability, good Anti-flammability and electrical insulating property, these excellent performances so that cable is suitable for high frequency signal transmission, and the stream of insulating materials Dynamic property is good, it is easier to processing and production.Wrapped one layer of outer layer after twisted synthesizing cable or direct twisted synthesizing cable after stranded core pair twist Band 3 is isolated, and keeps the structure of cable closer, the whole more rounding of cable, while increasing its intensity and hardness.3 outer layer of band Wrapped one layer of conductive fabric 4 plays the role of shielding outside electromagnetic interference and insulation blocking electric wire layer structure, while conductive fabric sheet There is body high conductivity, anticorrosive property, the performances such as tear-resistant to have been widely used for national defence, space flight, aviation, communication, doctor at present The industrial department with many applied microwaves, high frequency is treated, pollution of the electromagnetic wave to environment is reduced.Add one between conductive fabric 4 and band 3 Root drain wire shielding 5, such double layer screen can make cable have higher shield effectiveness, while drain wire can provide low electricity Hinder Grounding.The outermost layer of electric wire be sheath, sheath material have high resiliency, high-temperature resistant, it is tear-resistant the advantages that, meet simultaneously The standards such as CCC, UL, CSA, RoHS.And cable overall appearance rounding uniform and smooth.The conductive fabric shields encoder cable and is applicable in In high frequency signal transmission and the encoder system of reciprocating movement.
