Description

The boundling flat cable

Technical field

Utility model relates to a kind of flat type cable, especially integrates the boundling flat cable of multiple cable.

Background technology

The big-and-middle-sized engineering mechanical device that occasion such as bridge construction, port and pier is used, function is increasing, automaticity improves constantly, cable is proposed new requirement, not only require to realize multiple function, for example carry high and low pressure different dynamic power supply, therefore signal transmission such as remote intercommunication, picture control, data management need multiple cable to work simultaneously; But also require cable often to drag or be contained in retractable on the drum on the ground, therefore want to bear pulling force, torsion and good bending property.Realize above-mentioned functions in the prior art, employing be that the many cables of realizing corresponding functions are simply tied up combination.Cause and use trouble, because each cable tension performance, and stressed unbalanced, make disconnected core phenomenon takes place easily, the comprehensive tensile property of cable is poor, and use cost increases.Though the boundling flat cable is arranged in the prior art, function singleness all is for adapting to the specific occasion exploitation, still being not suitable for preceding purposes.For example:

The disclosed stacker-reclaimer flat cable of Chinese patent CN2618266, structure are two ends power line groups, and the centre is that 3 control line groups are formed.CN2655387 linear electric motors multicore flat cable, a side are the above control line conductors of three cores, and opposite side is the above holding wire conductor groups of three cores, between control conductor group and holding wire conductor group 3 above power line conductors is arranged.CN2836179 low-smoke non-halogen flame-retardant elevator control flat cable, there is strengthening core both sides, and the centre is arranged with stranded conductor core, video line.These flat cables, because at use object difference, and the overwhelming majority is powered for low electricity, the boundling function is comparatively simple, still inapplicable aforementioned use occasion still need improve, and develops a kind of flat type special cable of multi-functional more, suitable aforementioned instructions for use.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of boundling function many, and whole tensile property is good, does not disturb each other, boundling flat cable easy to use.

The utility model purpose realizes that main the improvement is to increase boundling function cable, and the multiple tracks shielding is set, reduce mutual electromagnetic interference between high voltage and telecommunication cable, and the low cable of tensile strength carried out reinforcement, thus overcome above-mentioned the deficiencies in the prior art, realize the utility model purpose.Specifically, utility model boundling flat cable, comprise the flat rubber sheath, the separated some function cables of built-in word order is characterized in that said function cable comprises high voltage power line group, control signal wire group, audio frequency and video line group, the low-voltage-powered line group of no sheath that is arranged in order from an end; Said high voltage power line group high pressure cable core has screen outward; Said control signal wire group by stranded composition of flexible steel cable strengthening core of rubber sheath, has screen by some insulated wire cores and center outward; Said audio frequency and video line group is made up of line is stranded with communicating by letter coaxial cable, and communication has screen outward to line.

For improving the bending property of forming bunched cable, the conductor in the said high voltage power line of utility model group, low-voltage-powered line group and the control signal wire group all adopts flexible conductor, and for example tinned conductor insulate and all adopts the good ethylene-propylene rubber of electrical property.

For further reducing the interference of high pressure core, the insulation shielding of each high pressure core adopts copper wire and dacron thread mixed weaving form, advantages of good shielding performance not only, all right double as earth connection function; In addition, the external shield of high pressure cable core, a kind of better employing metallic shield, for example copper wire braid shielded.

Order wire group audio frequency is to the line external shield, a kind of better employing metallic shield, for example copper wire braid shielded.

The low-voltage-powered line group of no sheath is made up of three insulation power cores and a Ground wire with insulation ocver core.

Utility model boundling flat cable, not only collect conveying of high and low pressure electric power and control signal and communication network and be transmitted as a cable, rated voltage 6/10kV and following high voltage power power supply can be provided, reach rated voltage 0.6/1kV and following low-voltage-powered power supply, strengthen the function of use of cable greatly; And better taken into account tension, the shielding of each cable, do not disturb each other.High voltage power cable core, control cable core always cover outside setting up outward, and communication increases screen outward to line, has reduced cable greatly to outside and mutual electromagnetic interference, guarantees the electric power transfer dependable performance, and it is accurate that the control signal instruction is transmitted, and the audio frequency and video effect is clear.Each core insulation shielding of high voltage power winding adopts copper wire and dacron thread mixed weaving form, and double as earth connection function has improved the security reliability that cable uses especially.The flexible steel cable strengthening core that has the rubber protection is placed by control signal wire group multicore small bore core central authorities, has both strengthened its tensile property, can guarantee continuous core in the cable use.Conductor adopts flexible conductor in high voltage power line group, low-voltage-powered line group and the control signal wire group, has effectively improved the cable bending property.Be spaced from each other between each line group, by the jacket rubber filling, make the construction of cable stable, overall performance is good, balanced each cable resistance to tension.Utility model boundling flat cable, also save discrete cable and needed sheath material separately, having installation than prior art lays conveniently, cable fabricating yard and expense have been saved, can be many for function, big-and-middle-sized engineering mechanical device that automaticity is high uses, and has well wear-resisting, corrosion resistant, weather-proof and tension and bending property.

Below in conjunction with a specific embodiment, further specify the utility model cable.
