Description
One, technical field:
The present invention relates to a kind of structure of radio frequency coaxial-cable, especially relate to a kind of novel structure that is suitable for the radio frequency coaxial-cable that test level uses.
Two, background technology:
In the last few years, fast development along with the microwave communication technology, whole set equipment has proposed many new requirements to the radio frequency transmission element, with regard to radio frequency (RF) coaxial connector and cable assembly, multifrnction connectors such as DC-Block connector, radio-frequency (RF) switch connector, signal lighting protection connector obtain widely applying in machine system, phase-compensated cable and cable assembly market are also in quick growth, and these new microwave devices play important effect to raising radio signal transmission quality, lifting machine system signal quality, simplification complete machine structure.
The structure of existing test cable is in the communication system test:
1) common flexible cable+stainless steel flexible hose+nylon wire braiding
The test cable of this structure now is widely used, and mainly is that the protection structure of cable outside is comparatively simple, and attaching is convenient.Stainless steel flexible hose is enclosed within cable outside, and the afterbody bracing means by connector combines both; Can not good antitorque commentaries on classics because the stainless steel flexible hose retractility is good, therefore overlapped one deck nylon mesh grid outside again, because the fastening effect of mesh grid, can reduce greatly because of reversing bending damage in the outside the inside cable, thus the reduction test error.
2) common flexible cable+spring+wire braid+sheath
The structure of this kind test cable is complicated than the former, need weave on stainless steel spring before the dress cable, squeezes one deck sheath after having woven again.The retractility of spring is more much bigger than the retractility of stainless steel flexible hose, the greatly then more effective inside cable of having protected of flexible scope can not pulled, prolonged the useful life of cable, can not reset, therefore woven one deck mesh grid outside in order to prevent spring from excessively being stretched; Same spring structure can not good antitorque commentaries on classics, so the outside has been squeezed one deck sheath again, has not only played protective effect but also has made whole cable feel more soft.
Present these two kinds of test cables that adopt; the inner cable that is adopted is the cable of common real core PTFE insulation system mostly; cable is not suitable for repeatedly crooked more firmly; and cable is bent, pulls through regular meeting in actual test process; in the course of time will influence the stability of amplitude-phase consistency of test cable own and phase difference; in order to eliminate the test error of self, added the protection of different structure in the outside of cable.What the former adopted is stainless steel flexible hose+nylon wire braiding, because the flexible scope of stainless steel flexible hose is less and harder, when firmly dragging test cable, if the words that inside cable length is shorter slightly than stainless steel flexible hose, stainless steel flexible hose does not just have the effect of sharing strength so, strength then all has been added on the inside cable, the long-term stressed excessive play that is easy to cause cable core, if inside cable is than stainless steel soft pipe range, then cable is inner at flexible pipe is not the nature elongation state just, the cable of often saying is being suppressed strength exactly, will influence the variation of test cable correlated performance index, finally influences the index of tested cable; The latter adopts stainless steel spring+metal wire knitted+sheath, the tension of the spring ability of dragging will be good with respect to stainless steel flexible hose many, and relative flexibility is fine, inside cable can not be subjected to the influence of external strength, the count of outer field woven wire cloth probably is about 70%, more sparse do not have the anti-twisting property of nylon mesh grid good, therefore one deck sheath has been squeezed in the outside, but still there is the gap between sheath and braid, crooked or still can produce relative displacement between the two when reversing when cable, can not eliminate crooked influence fully to inside cable.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology, and a kind of novel structure that is suitable for the radio frequency coaxial-cable that test level uses is provided, and it is poor that it has solved in the prior art measuring accuracy, the defective that useful life is short.
For achieving the above object, the technical solution used in the present invention is: a kind of novel structure that is suitable for the radio frequency coaxial-cable that test level uses, comprise core, it is characterized in that: be arranged with insulator, outer conductor one, outer conductor two, sheath one, spring, braid, sheath two, transition zone and sheath three on the described core successively.
Described core is the multiply core.
Described transition zone is band glue intermediate layer.
The material of insulator is a low density PTFE film band.
The material of described spring is high-intensity stainless steel material.
Compared with prior art; advantage and effect that the present invention has are as follows: employing be a kind of novel cable protection structure; this kind structure combines the advantage of two kinds of test cables of tradition; promptly adopted spring structure again with sheath and nylon mesh grid by band glue-line being connected together tightly; basically eliminated fully because outside stressed or reverse influence to inside cable; thereby guaranteed the precision of test cable and can reduce the performance index that influence institute's test cable owing to the test error of test cable own, because the protection structure of cable outer layer can also prolong the mechanical bend useful life of test cable.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention.
Five, embodiment:
Referring to Fig. 1: a kind of novel structure that is suitable for the radio frequency coaxial-cable that test level uses, comprise core 1, described core 1 is the multiply core, be arranged with insulator 2, outer conductor 1, outer conductor 24, sheath 1, spring 6, braid 7, sheath 28, transition zone 9 on the core 1 successively and close sheath 3 10, described transition zone 9 is band glue intermediate layer, the material of insulator 2 is a low density PTFE film band, and the material of described spring 6 is high-intensity stainless steel material.
The present invention is that spring 6 adopts high-intensity stainless steel material, the wire sheathing of outside winding, and its count reaches more than 90%, because the lay of braiding I is so that the torsional rotation force reinforcement of spring.Inner adopt spring+braid, though there is the constraint of braid the spring outside, certain clearance is arranged still between spring, not only resistance to bend(ing) is good, and resilience in time when being subjected to outside the pulling, has well protected inside cable not to be subjected to the external force function influence; What adopt is multiply heart yearn+low-density film lapped insulation, and the multiply heart yearn is more soft comparatively speaking, and flex life is more longer more durable; Insulator adopts that low-density film is wrapped to have a transmission rate height, loss is less, characteristics such as steady phasic property is good, be more suitable for being used as testing-level cable, the restrictive coating wall of outside is thin especially to be had only about 0.1～0.15mm, organically combine by transition zone and knit nylon layer and to become one, seem three layers and actually had only one deck, during in crooked and distortion this which floor between relative displacement can not take place when cable like this, improve the cable width of cloth in use greatly and reached phase stability mutually, guaranteed the accuracy of test.
