Abstract
The utility model relates to a miniature foamed-skin insulation coaxial cable, which comprises insulating cores. Each insulating core is formed by extruding a composite insulating layer outside a single solid copper conductor, each coaxial outer conductor is formed by lapping a layer of tinned copper wires outside the insulating core, each unit coaxial core is formed by extruding a layer of low-smoke halogen-free materials outside the outer conductor closely, and multiple unit coaxial cores are integrated to form a cable core which is covered by a polyester film covering layer and a low-smoke halogen-free sheath in sequence. The miniature foamed-skin insulation coaxial cable has the advantages that 1, the cores are fine in intensity and not easy to deform after multiple manufacturing procedures; 2, the inner layer of the cable guarantees index of communication and transmission, the outer layer of the cable functions as a supporting frame, and the integrated cable is fine in extensibility, high in coaxiality and stable in electrical performance; 3, solid skin serves as a frame so that low frequency index is stabilized properly; 4, the cable is high in screening density, small in size after processing of the outer conductors and fine in electromagnetic interference shielding effect; 5, the cable is remarkable in inflaming resisting performance and suitable for occasions with requirements on environmental protection and safety; and 6, the cable can be processed by common communication cable producing equipment, accordingly the cable is high in universality, convenient, simple and high in effectiveness.
Description
Technical field
The utility model relates to a kind of miniature diameter coaxial cable, particularly a kind of bubble skin insulation miniature diameter coaxial cable that is applicable to following transmission of analogue signal of frequency 30MHz and high-speed digital signal.This cable is mainly used in the transmission of radiofrequency signal in the electronic installation of fixing or mobile radio telecommunications and similar techniques.
Background technology
Along with the fast development of world today's telecommunication technology, communication equipment and electronic installation are more and more higher to the quality of signal transmission, for the cable of transmission channel, and high target, the design difficulty of high stability product highlights all the more.At present, domestic most of miniature diameter coaxial cable product adopts single chemical foaming technology can not satisfy the instructions for use that improves day by day.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of bubble skin insulation miniature diameter coaxial cable.Choosing structure Design and can reach the market customer requirements fully from composition material.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of bubble skin insulation miniature diameter coaxial cable, it is characterized in that: be included in single real core copper conductor and extrude the insulation heart yearn that one deck composite insulation layer constitutes outward, outside insulated wire cores, twine one deck tinned wird as coaxial outer conductor, be close to outer conductor and extrude one deck low smoke and zero halogen material outward and do inner sheath and constitute the coaxial core in unit; The coaxial core of many root units assembles cable conductor, its outer polyester film coating layer and low smoke and zero halogen oversheath of being provided with successively.
The beneficial effects of the utility model are: 1, construction of cable good stability: insulating barrier adopts the composite insulation layer of polyethylene foamed and real core polyethylene material promptly to steep the general chemical blowing individual layer insulation of skin insulation replacement, core rigidity intensity is good, and processing is difficult for deforming through multiple operation.2, insulating barrier good percentage elongation: composite insulation structure, internal layer have guaranteed the communications index, and skin has played the skeleton supporting role, combination back good-extensibility, axiality height, electric performance stablity.3, the low-frequency range singal reporting code is stable: general chemical blowing miniature diameter coaxial cable, and when 1MHz and 2MHz,, cable insulation cause impedance and decay leading indicator to distort often because of easily deforming, and there has been real core skin to do skeleton and well stablized the low-frequency range index.4, the outer conductor size is little: adopt tinned wird to twine shielding, and shielding density height, outer conductor processing back cable dimension is little, and electromagnetic interference shield is effective, is suitable for the occasion high quality digital signal transmission of the multiple cable of intensive layout.5, the feature of environmental protection is good: the cable inner sheath adopts the low smoke and zero halogen material, and fire resistance is superior, is fit to the Environmental Safety occasion and uses.6, easy to process: as to use general communication cable manufacturing equipment processing, highly versatile, convenient and simple high efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, bubble skin insulation miniature diameter coaxial cable, be included in single real core copper conductor 1-1 and extrude the insulation heart yearn that one deck composite insulation layer 1-2 constitutes outward, outside insulated wire cores, twine one deck tinned wird as coaxial outer conductor 1-3, be close to outer conductor 1-3 and extrude one deck low smoke and zero halogen material outward and be inner sheath 1-4 and constitute the coaxial core 1 in unit; The coaxial core 1 of many root units assembles cable conductor, its outer polyester film coating layer 2 and low smoke and zero halogen oversheath 3 of being provided with successively.Composite insulation layer 1-2 is the double-decker that sticks to one, and internal layer adopts polyethylene foamed material, the real core polyethylene material of outer employing.
