Description
Technical field
Sensor cable field is the utility model is related to, more particularly to a kind of special-shaped photoelectric compound cable.
Background technology
Electric unit in the photoelectric compound cable of existing in the market uses circular configuration, and the cable one of this structure is shape
Irregularly, easily there is lines in appearance, second, the contour structure size of cable is larger, occupancy installation space is more, third, cable is not because
Rule need to be filled cable core gap, increase processing technology difficulty, and besides the contour structure size of cable is big and gap
The addition of filler, product weight also will increase, this requirement to cable tensile strength is also a test.
Utility model content
Problem to be solved in the utility model is, overcomes the deficiencies of the prior art and provide a kind of reduction core gap
And filler, the high special-shaped photoelectric compound cable of structural strength.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of abnormal shape photoelectric compound cable, including allotype insulation conducting wire, optical cable, oversheath, the allotype insulation conducting wire
Including the three groups of fan for being enclosed with special-shaped insulating layer wire cores, three groups of fan wire cores are equal using concentric stranding structure
The even composition allotype insulation conducting wire that is intertwined, the inner wire of fan wire core are twisted using strand copper wire；It is described
Optical cable be located at the center of allotype insulation conducting wire, allotype insulation conducting wire is wrapped with protective layer, and protective layer is externally provided with shielded layer, screen
Cover layer and be externally provided with oversheath；The protective layer and the crevice place of allotype insulation conducting wire adjacent two-by-two are equipped with strengthening core, strengthen
Core material selects aramid fiber silk；Arc-shaped partition is equipped between the optical cable and each allotype insulation conducting wire.
Preferably, the protective layer is using the double-deck thin-film material with insulation performance.
Preferably, the thin-film material is polyester film.
Preferably, shielded layer is woven using tinned copper wire.
Preferably, the oversheath is to be coated on cable outermost layer by polyvinyl chloride hot extrusion to be formed.
The utility model has significant advantages and beneficial effects compared with prior art：Conducting wire forms sector structure, has
The gap reduced between traditional rule circle cable core of effect, strengthening core are arranged between segment conductor-core and circular protective layer only
Some cracks in, maximumlly using space, optical cable is integrated in sector conductor center, and integrated level is high, space hold is small；Optical cable
Obstructed between Special wire by arc-shaped partition, protect optical cable, improve service life.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to embodiment provided by the utility model, structure, feature
And its effect, describe in detail as after.
A kind of special-shaped photoelectric compound cable as shown in Figure 1, including allotype insulation conducting wire, optical cable 2, oversheath 5, it is described
Allotype insulation conducting wire includes three groups of fan wire cores 1 for being enclosed with special-shaped insulating layer 11, and three groups of fan wire cores are adopted
With the composition allotype insulation conducting wire that is intertwined of concentric stranding even structure, the inner wire 12 of fan wire core uses multiply
Copper wire is twisted；The optical cable 2 is using central tubular multi-core optical fiber, the center being arranged between three groups of fan wire cores,
Allotype insulation conducting wire is wrapped with protective layer 3, and protective layer is externally provided with shielded layer 4, and shielded layer is externally provided with oversheath 5；The guarantor
The crevice place of sheath and allotype insulation conducting wire adjacent two-by-two is equipped with strengthening core 6, strengthening core material selection aramid fiber silk；It is described
Optical cable and each allotype insulation conducting wire between be equipped with arc-shaped partition 7 made of steel band.
The protective layer 3 is using the double-deck thin-film material with insulation performance.
The thin-film material is polyester film.
The shielded layer 4 is woven using tinned copper wire.
The oversheath 5 is to be coated on the layer that cable outermost layer formed by polyvinyl chloride hot extrusion.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
