Abstract
The utility creatively provides a signal cable with resistance to compression blocking function, include by interior and enhancement inner core, conductor, insulating layer, outer conductor shield, buffer layer and oversheath outer setting, the conductor includes by the electrically conductive group of isolation layer divided, photosignal group, data signal group and analog signal group. The buffer layer is the rubber layer. The buffer layer with be equipped with steel band longitudinal welding's armor between the oversheath. The utility model discloses creating to have simultaneously and electrically conducting and the signal transmission function, the integrated level is high, convenient to use, and occupation space is little simultaneously, consequently practices thrift secret piping space. Signal cable inside has the enhancement inner core, and structural strength is high, shocks resistance, anti extrusion ability reinforce, and consequently, this signal cable is not fragile, long service life. Simultaneously, separate through the isolation layer between each electrically conductive group, data signal group and analog signal group, independent separately, shielding property is good, no signal interference.
Description
Technical field
The invention belongs to field of cable technology, especially relates to a kind of signal cable with resistance to compression function of shielding.
Background technology
Signal cable is widely used in the wire transmission network systems such as cable TV transmission network network system, closed-circuit television system, monitoring system, safety and protection system, it is as backbone, main line or service main, the information such as transmission television image, sound, data, symbol, it is also applied in the wire transmission network of other impedance matchings of similar applications, it is more suitably applied in the environment of laid condition rather harsh, reaches good laser propagation effect. Along with the living standard of people improves constantly, transmit information more really for obtaining, the requirement of coaxial cable is also more and more higher. Radio frequency coaxial-cable of the prior art, owing to cable designs existing defects, in work progress, often occur sheath after puncturing, directly to injure outer conductor and cable hits the flat serious quality problems such as weigh wounded, and the existing usual function singleness of radio frequency coaxial-cable, cannot realizing multi-purpose, difference in functionality needs different cables, causes underground piping space crowded in utter disorder.
Innovation and creation content
In view of this, the invention is directed to a kind of signal cable with resistance to compression function of shielding, has several functions, and integrated level is high, it is possible to be applied to the control of multiple signals, and the pipeline space of stringing is saved in easy construction simultaneously.
For reaching above-mentioned purpose, the technical scheme of the invention is achieved in that
A kind of signal cable with resistance to compression function of shielding, including the reinforcement inner core arranged from inside to outside, conductor, insulating barrier, outer conductor screen layer, cushion and oversheath; Described conductor includes some conductor wire groups, and described conductor wire group includes the photosignal line group, digital signal line group and the analog signal line group that separate by sealing coat.
Further, described cushion is rubber layer.
Further, it is provided with high intensity reinforcement in described cushion.
Further, described reinforcement inner core is polyvinyl plastic core or nylon core.
Further, described sealing coat is high density polyethylene (HDPE) foaming layer.
Further, the armor of steel band longitudinal measure it is provided with between described cushion and described oversheath.
Relative to prior art, a kind of signal cable with resistance to compression function of shielding described in the invention has the advantage that
1) having conduction and signal transfer functions, integrated level is high, easy to use, it is possible to be applied to the control of multiple signals, takes up room little simultaneously, therefore descends pipeline space frugally simultaneously.
2) this signal cable has reinforcement inner core, and structural strength is high, shock resistance, and anti-extrusion ability is strong, and therefore, signal cable is hardly damaged, long service life.
3) being separated by sealing coat between each conductor wire group, digital signal line group and analog signal line group, each independent, shielding is good, and no signal is disturbed.
Accompanying drawing explanation
The accompanying drawing constituting the part of the invention is used for providing being further appreciated by the invention, and the schematic description and description of the invention is used for explaining the invention, is not intended that the improper restriction to the invention. In the accompanying drawings:
Fig. 1 is the structural representation of the invention.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in the invention and the feature in embodiment can be mutually combined.
Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of signal cable with resistance to compression function of shielding, as it is shown in figure 1, include the reinforcement inner core 1, conductor 1, insulating barrier 3, outer conductor screen layer 4, cushion 5 and the oversheath 6 that arrange from inside to outside; Described conductor 1 includes some conductor wire groups 7, and described conductor wire group 7 includes the photosignal line group 8, digital signal line group 9 and the analog signal line group 10 that separate by sealing coat 2.
Described cushion 5 is rubber layer. There is the effect of protection inner conductor, cable long service life.
Wherein, being provided with high intensity reinforcement in described cushion 5, structural strength is high, durable, is hardly damaged, long service life.
Wherein, described reinforcement inner core 1 is polyvinyl plastic core or nylon core, it is possible to arbitrarily bends and does not rupture, it is possible to be applicable to the wiring environment that bending is complicated.
Wherein, described sealing coat 11 is high density polyethylene (HDPE) foaming layer.
Wherein, it is provided with the armor of steel band longitudinal measure between described cushion 5 and described oversheath 6, and on armor, is provided with embossing so that this signal cable is firm in structure, is unlikely to deform.
It should be noted that the steel band of above-mentioned armor is high magnetic conduction galvanized steel strip, having good anticorrosion and shielding properties, structural strength is high, it is possible to protect its internal cable core to damage from external impacts.
The coaxial cable that the invention provides has conduction and signal transfer functions simultaneously, integrated level is high, easy to use, the control of multiple signals can be applied to, and cable takes up room little, therefore, poling pipeline space can be saved, once connect up, can be applicable to multiple signals control, convenient construction. And cable has reinforcement inner core 1, structural strength is high, and shock resistance, anti-extrusion performance is good, is hardly damaged, long service life. Meanwhile, each photosignal line group 8, separated by sealing coat 2 between digital signal line group 9 and analog signal line group 10 so that each line group is all each independent, and shielding is good, and no signal is disturbed.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment of making, equivalent replacement, improvement etc., should be included within the protection domain of the invention.
