Abstract
The utility model provides a sensor cable for tow chain, including insulation core, shielding layer, oversheath, its characterized in that: the outer cladding of shielding layer have the oversheath, be equipped with the cable core that forms by 4~25 insulation core transposition in the shielding layer, insulation core form by inner conductor and the insulating layer of cladding outside the inner conductor, shielding layer inboard and insulation core between still be equipped with the enhancement core. Compared with the prior art, the utility model apparent advantage and beneficial effect have: reasonable, the technical maturity of this cable design has good compliance, bendability, intensity is high, the wearability is good, the cable has the feature of environmental protection, can not cause the corruption to precision equipment, has guaranteed the personal safety and can not cause the pollution to the atmospheric environment simultaneously, can satisfy machine -building tow chain trade and high -speed portable machine part's operation requirement.
Description
Technical field
The utility model belongs to sensor cable field, particularly a kind of drag chain sensor cable using at machine-building drag chain industry, Robotics or the removable machine part of high speed.
Background technology
Along with social development, also progressively increase progressively for the cable demand of sensor field, frequently move at machine-building drag chain industry requirement cable, bending. Current drag chain cable general structure is to adopt soft PVC insulation and soft PVC jacket insulation, and its shortcoming is in the time working long hours, heart yearn extrusion, insulated hull breakage, braid shielded net is damaged affects shielding properties, and service life is short, and has a strong impact on electric property.
Summary of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of machine industry instructions for use that can meet is provided, and has the environmental sensor cable of good bendability, frequent mobile, bending, long service life.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of drag chain sensor cable, comprise insulated wire cores, screen layer, oversheath, it is characterized in that: described screen layer is coated with oversheath, in screen layer, be provided with by 4 ~ 25 stranded cable cores that form of insulated wire cores, described insulated wire cores is made up of inner wire and the insulating barrier being coated on outside inner wire, between described screen layer inner side and insulated wire cores, is also provided with strengthening core.
Further, described strengthening core material selection aramid fiber silk, is twisted into aramid fiber strengthening core by structure with machine when stranding, can strengthen the endwise tensile strength of cable.
Further, described inner wire adopts the incorgruous stranded ultra-fine bare copper wire of multilayer to make, and this structure makes this sensor cable have good flexibility and less bending radius, is applicable to frequently motion repeatedly of drag chain.
Further, the outer painting of described insulating barrier is shaped with separation layer, and this separation layer can be avoided adhesion between core, makes to produce between insulated wire cores relative sliding, and can play the effect that strengthens cable flexibility, makes cable more soft compared with common cable.
Further, inside and outside the enclosing of described screen layer is equipped with nonwoven layer.
Further, described screen layer adopts tin-coated copper braiding structure, can effectively protect from inner and outside interference.
Further, described insulating barrier adopts polypropylene material.
Further, described oversheath adopts flame retardant polyurethane.
The utility model compared with prior art has significant advantage and beneficial effect: this cable design rationally, technical maturity, there is good flexibility, bendability, intensity is high, wearability good; Cable has the feature of environmental protection, can not cause corrosion to precision equipment, has ensured personal safety and can not pollute atmospheric environment simultaneously, can meet the instructions for use of machine-building drag chain industry and the removable machine part of high speed.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model;
Wherein 1, strengthening core, 2, inner wire, 3, insulating barrier, 4, nonwoven, 5, screen layer, 6, oversheath.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to the detailed description of the invention providing according to the utility model, structure, feature and effect thereof, be described in detail as follows.
A kind of drag chain sensor cable as shown in Figure 1, comprise insulated wire cores, screen layer 5, oversheath 6, described screen layer 5 is coated with oversheath 6, in screen layer, be provided with by 4 ~ 25 stranded cable cores that form of insulated wire cores, described insulated wire cores is made up of inner wire 2 and the insulating barrier 3 being coated on outside inner wire, between described screen layer inner side and insulated wire cores, is also provided with 6 strengthening cores 1.
Described strengthening core 1 material selection aramid fiber silk, is twisted into aramid fiber strengthening core by structure with machine when stranding, can strengthen the endwise tensile strength of cable.
Incorgruous stranded the making of bare copper wire multilayer that described inner wire 2 is 0.1mm by multiply ultrafine diameter, this structure makes this sensor cable have good flexibility and less bending radius, is applicable to frequently motion repeatedly of drag chain.
The described outer painting of insulating barrier 3 is shaped with separation layer, and this separation layer can be avoided adhesion between core, makes to produce between insulated wire cores relative sliding, and can play the effect that strengthens cable flexibility, makes cable more soft compared with common cable.
Inside and outside the enclosing of described screen layer 5 is equipped with nonwoven 4.
Described screen layer 5 adopts tin-coated copper braiding structure, can effectively protect from inner and outside interference.
Described insulating barrier 3 adopts polypropylene material.
Described oversheath 6 adopts flame retardant polyurethane.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model. All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
