Abstract
Inner conductor extrusion molding FEP's half gentle coaxial cable of high impedance includes inner conductor, PTFE insulating layer, outer conductor, the restrictive coating of coaxial setting in proper order from inside to outside, be equipped with the FEP layer between inner conductor and the PTFE insulating layer, just the thickness on FEP layer is less than or equal to 0.1mm. The utility model discloses novel structure, reasonable in design through set up the FEP layer between inner conductor and PTFE insulating layer, have strengthened anchoring strength between the two, the automatic wire stripping of being convenient for, and do not influence the holistic performance of cable.
Description
[technical field]
The utility model relates to field of cable technology, particularly the high impedance semi-flexible coaxial cable of a kind of inner wire extrusion molding FEP.
[background technology]
In existing high impedance semi-flexible coaxial cable, the impedance 75 Ω cable inner conductor wire diameter of 141 half soft series is 0.53mm, the impedance 100 Ω cable inner conductor wire diameter of 141 half soft series is 0.28mm, because inner wire is thin, the adhesion of inner wire and insulating barrier is very little, the unfavorable effect brought thus is, in the wire stripping process of cable, insulating barrier is easy to depart from from inner wire, causes being difficult to outer conductor just to be peeled off from insulation.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the high impedance semi-flexible coaxial cable of a kind of inner wire extrusion molding FEP, both ensure that the continuity of insulation, and in turn enhanced the adhesion between inner wire and PTFE insulating barrier, be convenient to automatic stripping.
For solving the problems of the technologies described above, the utility model have employed following technical proposals:
The high impedance semi-flexible coaxial cable of inner wire extrusion molding FEP, comprise inner wire, PTFE insulating barrier, outer conductor, the restrictive coating of coaxial setting successively from inside to outside, be provided with FEP layer between described inner wire and PTFE insulating barrier, and the thickness of described FEP layer is less than or equal to 0.1mm.
Preferably, the thickness of described FEP layer is 0.05mm.
Preferably, be also provided with separator between described PTFE insulating barrier and outer conductor, described separator is FEP layer.
Preferably, the thickness of described separator is 0.05mm.
Preferably, described outer conductor is silver-plated copper strips outer conductor.
Preferably, described inner wire is silver-plated copper conductor.
Compared with prior art, the beneficial effects of the utility model are: in the high impedance semi-flexible coaxial cable of inner wire extrusion molding FEP described in the utility model, by setting up FEP layer between inner wire and PTFE insulating barrier, enhance adhesion between the two, be convenient to automatic stripping, and do not affect the performance of whole cable.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation two of the utility model embodiment.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is described further.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, the high impedance semi-flexible coaxial cable of inner wire extrusion molding FEP, comprise inner wire 1, PTFE insulating barrier 3, outer conductor 4, the restrictive coating 5 of coaxial setting successively from inside to outside, be provided with FEP layer 2 between described inner wire 1 and PTFE insulating barrier 3, and the thickness of described FEP layer 2 is less than or equal to 0.1mm.
The utility model is rational in infrastructure, novel in design, the outer first extrusion molding one deck FEP layer 2 of inner wire 1, subsequently at FEP layer 2 outer extrusion molding PTFE insulating barrier 3, because the adhesion of FEP layer 2 and inner wire 1 is beaten, the adhesion of FEP layer 2 and PTFE insulating barrier 3 is also large, thus solves by setting up FEP layer 2 problem that between inner wire 1 and PTFE insulating barrier 3, adhesion is little, and in the wire stripping process of cable, PTFE insulating barrier 3 is easy to the problem departed from from inner wire 1, facilitates automatic stripping.
In addition, because FEP layer 2 is outer and PTFE insulating barrier 3 electrical property is very close, the adhesion so both enhancing cable facilitates automatic stripping, in turn ensure that the continuity of insulation, and the overall performance of cable is constant.
The thickness of described FEP layer 2 can be 0.1mm, also can be 0.05mm.
Say from structure, preferably, also separator is had additional between described PTFE insulating barrier 3 and outer conductor 4, described separator is add the carefully thin FEP layer being attached to PTFE insulating barrier 3 outer surface, its thickness is 0.05mm, and like this, soft PTFE insulating barrier 3 does not directly contact with outer conductor 4, the substitute is the smooth and FEP layer that fragility is high, thus prevent outer conductor 4 to be difficult to peel off from PTFE insulating barrier 3.Because outer conductor 4 sticks on FEP layer, and PTFE insulating barrier 3 can not adhere to each other with FEP layer, thus in wire stripping process, outer conductor 4 is peeled off from PTFE insulating barrier 3 together with the FEP layer as separator.
In above-mentioned preferred embodiment, between increase FEP layer 2 and PTFE insulating barrier 3 while adhesion, weaken the adhesion between PTFE insulating barrier 3 and outer conductor 4, wire stripping convenience, efficiency are high, and are convenient to the automation realizing wire stripping.
In addition, described outer conductor 4 is silver-plated copper strips outer conductor, and described inner wire 1 is silver-plated copper conductor.Certainly, above material, only with for example, when not departing from the utility model protection range, can select other materials be applicable to substitute.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to the utility model claims.
