Abstract
The invention relates to a photoelectricity integrated mixed cable which comprises a power transmission line (1), a signal transmission line (2), an aramid yarn core (3), a constraint layer (5) and an aramid yarn braid layer (7). The constraint layer (5) is arranged in the aramid yarn braid layer (7). At least one power transmission line (1), the aramid yarn core (3) and at least one signal transmission line (2) are arranged in the constraint layer (5). The aramid yarn core (3) is placed at the center of the aramid yarn braid layer (7). The power transmission line (1) and the signal transmission line (2) are evenly distributed in the sealed space formed by the aramid yarn core (3) and the constraint layer (5). An inflaming retarding belt layer (6) is arranged between the aramid yarn braid layer (7) and the constraint layer (5). The photoelectricity integrated mixed cable has the advantages of being small in outer diameter, light in weight and small in occupied space, good compressive property and great bending property are achieved, and the cable can be used in an narrow environment where the cable needs to be bent for multiple times.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of optoelectronic integration is mixed cable.
Background technology
Existing optical fiber cable is mainly used in the signal transmission of telecommunications, computer and television network broadcast, mostly can not conduct electricity, and is difficult to satisfy the user demand that communication terminal device is powered simultaneously.In order to strengthen the use function of optical cable, satisfy the needs that optical cable some occasion in transmission course requires supply of electric power, also lay resource in order to save simultaneously, had at present photoelectric mixed cable.But present common photoelectric mixed cable, it is outside generally the oversheath of the macromolecular material that one deck extrudes by expressing technique.Jacket material commonly used is generally polyethylene or polyvinyl chloride, because the character of material itself, the bending property of this oversheath is not high; Reach the requirement of anti-strong pressure for the barrier propterty that makes oversheath, that generally all will do is very thick, and the size of mixing like this cable can be very large, has further reduced the bending property of mixing cable.
And when under the environment such as some occasion such as aircraft, steamer, mainframe computer inside, using, because the inner space of these environment itself is very narrow and small, and required telecommunication apparatus is very various again, so the path of cable is very complicated, need to be repeatedly crooked in narrow space, existing photoelectric mixed cable size is large, and bending property is large, can not meet the requirements.
Chinese patent application number: 200620165440.3 disclose a kind of New Photoelectricity Mixed Cable, comprise central reinforce member, central reinforce member be provided with an optical cable and Duo Gen shielded power supply line, the outer waterstop that is arranged with of optical cable and shielded power supply line, the outer fire retardant jacket that is arranged with of waterstop all around.Such structural bending performance is not high, when repeatedly crooked in small space, can not meet the demands.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of optoelectronic integration with bending property of good compressive property and excellence to mix cable, external diameter is little, lightweight, it is little to take up room, and can and need cable repeatedly to use in the crooked environment at narrow space.
Purpose of the present invention is achieved through the following technical solutions: a kind of optoelectronic integration is mixed cable, it comprises power transmission line, signal transmssion line, the aramid fiber yarn core, bond course and aramid yarn braid, it is inner that bond course is arranged at the aramid yarn braid, be provided with at least one power transmission line in the bond course, aramid fiber yarn core and at least one signal transmssion line, the aramid fiber yarn core is positioned at the center of aramid yarn braid, power transmission line and signal transmssion line are uniformly distributed in the enclosure space of aramid fiber yarn core and bond course formation, also are provided with fire-retardant belt between aramid yarn braid and the bond course.
The cross section of described aramid yarn braid is annular.
Described power transmission line and signal pipeline are wrapped in respectively the inside of insulating barrier.
The count of described aramid yarn braid is not less than 90%.
Described insulating barrier is made by the fire-proof insulation material.
The present invention has the following advantages:
1, the use of aramid yarn and insulating barrier has improved the fire resistance that mixes cable, can work under harsh environment.
2, external diameter is little, and is lightweight, takes up room little, has superior bending property and good anti-pressure measurement performance, easy construction.
3, the count of aramid yarn braid is not less than 90%, has powerful barrier propterty.
