The photoelectric composite cable can bear repeated stretching, bending and twisting force. The sheath disclosed by the invention is durable, and can bear high-speed start and brake. The photoelectric composite cable is light in weight, small in volume and suitable for a skillful and efficient crane. The photoelectric composite cable has good signal transmission performance in mechanical movement such as frequent movement and bending.
Description
Technical field
The present invention relates to the optoelectronic composite cable of a kind of simultaneously transmitting optical signal and electric power.
Background technology
Along with the 4000000000000 progressively enforcements of planning that country expands domestic demand, the development of the big machinery enterprise of China has welcome wide development space, and particularly the material carrying machine demand obviously increases.Handling machinery is of a great variety, wherein comprises from the small-scale bridge crane for the production of line, to the large-scale bank crane (STS) of deep water harbour, and is used for rail-mounted gantry crane (RMG), ship unloaders, bucket-wheel stacker reclaimer of intermodal freight terminal etc.According to the statistics of mechanical industry federation, it is 30% that in first trimester, 2009, domestic material carrying machine and associated components quantity on order increase by on a year-on-year basis, and the same period in 2008, amplification only was 0.75%.Mechanical industry federation carries out the kind expression of deputy chairman Cai Wei, and the situation that situation in 2009 was estimated than the beginning of the year is better.
But, with the critical component of the material carrying machine of fiber unit, need by external import such as moving electric power transmission and control communication cable (optoelectronic composite cable), cause the device fabrication cycle long, cost is expensive.Enterprise is in a disadvantageous position in the competition in market.Because this type of optoelectronic composite cable service condition very severe, larger pulling force, distortion power are born in the folding and unfolding that in use often need to drag or reel; Also because operational environment is complicated, expose to the sun and rain simultaneously, often be subject to the pounding of ore, goods fragment and foreign material, bump, scrape, mill etc., make cable cover(ing) be easy to mechanical damage occurs and scrap.
Summary of the invention
The objective of the invention is to provide a kind of optoelectronic composite cable, to solve problems of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of optoelectronic composite cable, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, it is characterized in that: described cable inner core comprises shielding core, optical cable and ground core, and shielding core, optical cable and ground core twist together, and extrude inner sheath at the cable inner core; Cable outer layer is followed successively by fibrage armour, oversheath from inside to outside.
In one embodiment of the invention, described shielding core has three, and the ground core has two, one on optical cable, and three shielding cores are 120 ° of phase angle circle distribution, and two ground cores and an optical cable are separately positioned among the gap of adjacent two shielding cores.
In one embodiment of the invention, described shielding core is followed successively by conductor, inner semiconductor layer, insulating barrier, out semiconductor layer from inside to outside.
In one embodiment of the invention, the conductor of described shielding core and ground core is Cu-CATH-1 line by wire drawing and annealing, the zinc-plated processing of environment-friendly type with single line.
In one embodiment of the invention, closely sticking glutinous between described oversheath, fibrage armour and the inner sheath three.
The present invention can tolerate stretching, the bending and torsion power of repetition; Sheath of the present invention is durable in use, can bear high-speed starting and braking; The present invention is lightweight, volume is little, is applicable to dexterity and efficient crane; The present invention should have good signal transmission performance in the frequent Machine Movement Process such as mobile, crooked.
Characteristics of the present invention can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, further set forth the present invention below in conjunction with specific embodiment.
As shown in Figure 1, a kind of optoelectronic composite cable comprises the cable inner core and wraps in the outer cable outer layer of cable inner core.The cable inner core comprises shielding core 10, optical cable 1 and ground core 9, in the present embodiment, shielding core 10 has three, ground core 9 has two, optical cable 1 has one, three shielding cores 10 are 120 ° of phase angle circle distribution, and two ground cores 9 and an optical cable 1 are separately positioned among the gap of adjacent two shielding cores, and shielding core, optical cable and ground core twist together.Shielding core 10 is followed successively by conductor, inner semiconductor layer 3, insulating barrier 4, out semiconductor layer 5 from inside to outside.The conductor of shielding core 10 and ground core 9 is Cu-CATH-1 line 2 with single line, the Cu-CATH-1 line adopts " double end " big drawing machine of the production of German NIEHOFF company to carry out wire drawing and annealing, the zinc-plated processing of environment-friendly type, make behind the wire drawing and annealing wire diameter and elongation comparatively unified, stable, ensured the production of cable conductor with single line.After the Cu-CATH-1 line is stranded, press and the school circle, prevent the strand wire jumper.
Extrude inner sheath 6 at the cable inner core; Cable outer layer is followed successively by fibrage armour 7, oversheath 8 from inside to outside.Closely sticking glutinous between oversheath 8, fibrage armour 7 and inner sheath 6 threes.Fibrage armour 7 effectively raises the braid mechanical performance by the angle of weave of reasonable control braid, the control weaving quality, guarantee that braid is smooth, nothing is jumped silk, the particularly processing of joint, can effectively avoid the impact of weaving quality on the mechanical performance of cable.
The present invention can tolerate stretching, the bending and torsion power of repetition; Sheath of the present invention is durable in use, can bear high-speed starting and braking; The present invention is lightweight, volume is little, is applicable to dexterity and efficient crane; The present invention should have good signal transmission performance in the frequent Machine Movement Process such as mobile, crooked.
Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and the specification is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the present invention.The protection range that the present invention requires is defined by appending claims and equivalent thereof.
