Abstract
The utility model relates to a mechanical amplitude-phase stable testing cable, which is composed of an inner conductor, an insulation layer, an outer conductor and a sheath, wherein the outer conductor is a composite screened outer conductor, namely a combination of an inner layer supplied silver-coated copper flat tape axially wrapping around the screened outer conductor, and the outer conductor of braid silver-coated copper wires of an outer layer. The utility model has simple integral structure, sound stability, low standing wave, stable amplitude and phase, which has wide application prospect in fields of radio communication, military radar, electronic countermeasure, internal equipment and instruments of airplanes and warship, satellite communications and the like.
Description
Technical field
The utility model belongs to field of cables, relates in particular to the steady phase test cable of a kind of mechanical fixed ampllitude.
Background technology
The steady phase test cable of employed in the market mechanical fixed ampllitude, it also is the form of coaxial cable, constitute by inner wire, insulating barrier, outer conductor and sheath, its outer conductor generally adopts the disc type around-packing technology, defective such as exist that tension force is inhomogeneous, unstable properties and processing length are short, vibration phase is stable and amplitude stabilization is all lower, causes its measuring accuracy also lower.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the steady phase test cable of mechanical fixed ampllitude that a kind of vibration phase stability and range stability are good, the line segment processing length is long is provided.
The purpose of this utility model is achieved through the following technical solutions:
The steady phase test cable of a kind of mechanical fixed ampllitude, constitute by inner wire, insulating barrier, outer conductor and sheath four parts, wherein outer conductor is comprehensive shielded outer conductor, i.e. the wrapped shielding outer conductor of silver-plated flat copper tape spool formula of internal layer and the assembly form of outer field braiding silver-coated copper wire outer conductor.
And described inner wire is real core or stranded silver-coated copper wire inner wire, and described sheath is the perfluoroethylene-propylene sheath.
Advantage of the present utility model and good effect are:
1. the inner wire of the steady phase test cable of this mechanical fixed ampllitude adopts real core or stranded silver-coated copper wire, has advantages such as temperature resistant grade height, oxidation resistance be strong; Outer conductor adopts the wrapped method of shaft type, and it is tightr that outer conductor is contacted with insulating barrier, and electrical structure is more stable, and can effectively improve the shield effectiveness of cable after weaving silver-coated copper wire again.The machining accuracy of this test cable obtains bigger raising, and the wrapped precision of the axial dimension of outer conductor reaches ± 0.08mm; The processing length of line segment extends to 150m by 80m, has improved continuous production length effectively, and Stability Analysis of Structures, and performance index are good, and the crooked phase stability of cable goods is ± 4 ° at 18G, vibration phase stability≤30 * 10
-6, range stability 5%.
2. the utility model overall simple, have that structural stability is good, standing wave is little, the outstanding feature of amplitude and phase stabilization is with a wide range of applications in radio communication, military radar, electronic countermeasures, aircraft and fields such as warship internal equipment, instrument and satellite communication.

Fig. 1 is a cross section of the present utility model cross-sectional schematic.
Embodiment
Below in conjunction with accompanying drawing, embodiment further specifies to the utility model; Following embodiment is illustrative, is not determinate, can not limit protection range of the present utility model with following embodiment.
The steady phase test cable of a kind of mechanical fixed ampllitude is made of inner wire 5, insulating barrier 4, outer conductor and sheath 1 four parts, and wherein, inner wire adopts real core or stranded silver-coated copper wire, makes inner wire have characteristics such as temperature resistant grade height, oxidation resistance be strong; Insulating barrier adopts PTFE polytetrafluoroethylmaterial material commonly used to make; Outer conductor is comprehensive shielded outer conductor, is the assembly form that adopts wrapped shielding outer conductor 3 of silver-plated flat copper tape spool formula and braiding silver-coated copper wire outer conductor 2, weaves the structure of silver-coated copper wire after promptly silver-plated flat copper tape spool formula is wrapped again; Sheath can adopt perfluoroethylene-propylene (FEP) material and extrude through thermoplastic and process.
In the utility model, the processing technology of each part is a prior art, does not repeat them here.
