Abstract
The utility model relates to a towline cable in the cable field. The cable sequentially comprises an outer protective layer, an insulated layer, a cable core from the outer to the inner, the inner of the insulated layer is uniformly distributed with the cable core; wherein, the wire core comprises an intertexture conductor and an inner conductor being coaxial with the intertexture conductor; the inner conductor comprises a brass wire and a spin silk twisted. The integrated structure of the towline cable is uniform, and the design is reasonable; the long service life provides security and economy; the inner conductor adopts the structure of that the brass wires and the spin silks are twisted in a small pitch; in the precondition of ensuring carrying flux, the structure enables the conductor has the stated retractility and intensity, good flexibility and bending, good tensile strength, the towline cable can be suitable to different radius towline bending motion and frequent movement.
Description
Technical field
The utility model belongs to field of cables, especially a kind of drag chain cable.
Background technology
Common cable is not owing to need to possess any pulling force and inner twist, and therefore the performance index aspect motions such as flexibility, retractility, tensile strength are relatively poor.In a single day this class cable is stretched or produces inner strand power, tends to take place lead fracture of wire, broken string, wrapped phenomenon such as break.Along with the fast development of science and technology, it is perfect that the plant industrial expansion has been tending towards, and the cable demand that is used for this field also progressively increases progressively.Especially in commercial Application such as robot, generally adopt drag chain cable, and the stroke of drag chain cable may reach 10m.Present drag chain cable is malfunctioning owing to machinery will take place when being everlasting 2～3m reasons in structure, or can not reach the transmission range of length like this owing to lack flexibility, thereby has influenced industrial machinery people's development.Therefore, a kind of drag chain cable that has high flexibility and can bear certain bending stress of research has important practical significance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, reasonable in design, can satisfy frequent moving and the crooked drag chain cable that moves, be applicable to the bending stress occasion of flexible rail motion, the motion of plant equipment drag chain and frequent mobile apparatus.
The utility model is achieved through the following technical solutions:
A kind of drag chain cable, this cable is made of outer jacket, separator, cable core from outside to inside successively, uniform installation cable core in separator is characterized in that: cable core is made of knitted conductor and the inner wire coaxial with it, and this inner wire is by copper wire and spin the synthetic fibre skein silk and knit and form.
And, the composite material that described outer jacket adopts rubber and polyvinyl chloride to constitute.
And described knitted conductor is the Polyamide Yarns knitted conductor.
Advantage of the present utility model and good effect are:
1. inner wire of the present utility model adopts copper wire and spins synthetic fibre silk fine pith braiding structure, under the prerequisite that guarantees ampacity, this structure makes conductor have certain retractility and intensity, have good flexibility, bendability, good tensile strength makes drag chain cable can adapt to the bending motion and frequent the moving of different radii drag chain.
2. separator is isolated cable core and outer jacket, and cable core evenly is arranged in the separator inner edge closely, makes outer jacket shell head easily according to user's service condition.
3. outer jacket can adopt rubber and polyvinyl chloride composite materials, this material not only has high flexibility, also have oil resistant and characteristics such as wear-resisting simultaneously, make obtained drag chain cable be applicable to the bending stress occasion of flexible rail motion, the motion of plant equipment drag chain and frequent mobile apparatus.
4. this drag chain cable overall structure is even, reasonable in design, and working life provides fail safe and economy for a long time, is applicable to that Robotics and machine manufacturing and other need the occasion of high flexibility drag chain cable.
Description of drawings
Fig. 1 is that subjective figure is analysed and observe in cross section of the present utility model;
Fig. 2 is the structural representation of the inner wire of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.
This drag chain cable is made of outer jacket 1, separator 2, cable core from outside to inside successively, the composite material that outer jacket adopts rubber and polyvinyl chloride to constitute, uniform installation cable core in separator, separator is isolated cable core and outer jacket, cable core evenly is arranged in the separator inner edge closely, be furnished with seven cable cores in the present embodiment in separator, the quantity of this cable core can be set as required.Cable core is made of knitted conductor 3 and the inner wire 4 coaxial with it, and this knitted conductor is the Polyamide Yarns knitted conductor; Inner wire (referring to Fig. 2) by copper wire 5 with spin synthetic fibre silk 6 strands and knit and form; The interval strand that this strand mode of knitting can be a fine pith is knitted, and also can be that many compound strands of fine pith are knitted, and knits for twisting at interval in the present embodiment, and its pitch is T.
Claims (3)
