Abstract
The utility model relates to a data bus cable for transmitting the differential signal, comprising an insulation electric wire composed of a FEP foam insulation layer outside an inner conductor, a flat wire woven shield, a round wire woven shield and a FEP sheath, wherein the four insulation electric wires are star quad structures and the flat wire woven shield, the round wire woven shield and the FEP sheath are arranged outside the insulation electric wire in turn. The beneficial effects are that: high temperature resistance: the product resists the temperature of 200 DEG C; low temperature resistance: working temperature of -65 DEG C for long time; small attenuation: because the insulation uses the foam FEP material, the medium loss is greatly reduced; good fire resistance property: because the FEP material has the very high flame retardant property and is flame-proof; strong shielding property: the flat wire woven structure greatly increases the electromagnetic interference performance of the product and the shielding attenuation of the product achieves 100dB; small outer diameter: because of the star type structure design, the outer diameter of the product is greatly reduced.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of data bus cable that is used for differential signal transmission that is used for fields such as Aero-Space, electronics.
Background technology
Along with the develop rapidly of Aeronautics and Astronautics and electronics industry and defence engineering, the cable of signal transmission usefulness is proposed higher requirement, cable develops to directions such as miniaturization, in light weight, high temperature resistant, anti-electromagnetic interference.General data cable is third rare with polyethylene foamed, polyethylene, perfluoroethylene, polytetrafluoroethylene is as insulating material, all poor aspect fire-retardant, intensity, signal attenuation index and the high and low temperature resistance, can not satisfy the job requirement of complete machine with these materials.
Summary of the invention
In view of the deficiency that prior art exists, it is a kind of high temperature resistant, low temperature resistant, in light weight that the utility model provides, the data bus cable that is used for differential signal transmission (LVDS) that external diameter is little.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of data bus cable that is used for differential signal transmission, it is characterized in that: the conductor that included is provided with insulated electric conductor, lenticular wire woven shield, circle line woven shield and the FEP sheath that one deck FEP foaming insulation layer constitutes outward, four described insulated electric conductors are star-quad construction, are provided with lenticular wire woven shield, circle line woven shield and FEP sheath outside it successively.
The beneficial effects of the utility model are: high temperature resistant: insulating barrier, sheath all adopt the FEP material, and the high temperature resistant heatproof of product that can make reaches 200 ℃; Low temperature resistant: the low temperature resistant temperature that works long hours can reach-65 ℃.It is little to decay: because foaming FEP material has been adopted in insulation, greatly reduce the loss of medium.Good flame resistance: because the FEP material has very high fire resistance, difficult combustion.Shielding is strong: the structural design of lenticular wire braiding can improve the anti-electromagnetic interference capability of product greatly, and the shielding attenuation of product can reach 100dB.External diameter is little: owing to adopted star-like structural design, so reduced the external diameter of product greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, be used for the data bus cable of differential signal transmission, the conductor 1-1 that included is provided with insulated electric conductor 1, lenticular wire woven shield 2, circle line woven shield 3 and the FEP sheath 4 that one deck FEP foaming insulation layer 1-2 constitutes outward.
With the stranded silver-plated copper monofilament of electric wire bunch of cables line machine as inner wire 1-1, constitute insulated electric conductor 1 at inner wire 1-1 external application high-temperature physics foam extrusion machine extrusion foaming FEP insulating barrier 1-2, thoroughly do away with edge electric wire 1 to four with star quadding machine and twist together the formation star-quad construction, outside it, adopt lenticular wire braiding machine braiding one deck silver-plated copper lenticular wire woven shield 2, outside lenticular wire woven shield 2, weave the silver-plated copper round wire woven shield 3 of one deck with 16 ingot high-speed knitters again, outside circle line woven shield 3, extrude FEP sheath 4.
