Abstract
The utility model is regarding an improvement of spring cable, and especially relates to a spring cable with good safety and long service life, which is characterized in that the spring steel wire adheres on the inside of the peripheral screw of the cable. The utility model overcomes the shortage of the prior art, effectively guarantees that the spring steel wire not to abrade or pierce the insulating coat of the conductor, and greatly increases the safety of the cable. The spring steel wire is arranged on the inside of the cable screw and does not effect normal use. The gaps among the core wires adopt rubber filling and the core wires are once formed with the sheath by squeezing. Not only that the suppleness of the cable is increased, but also the integrality of the wire core is good. When the cable bears torsional moment, each core wire does not shift and cause the distortion of the cable. Also, when the cable is vertically used and the lower end bears relatively great torsional force, the phenomena of torsional deformation, bulging, skin abrading, and core wire breaking off do not occur, and thus the safety of cable is greatly increased.
Description
Technical field
Utility model is about the improvement to spring cable, and it is good to relate in particular to a kind of fail safe, the spring cable of long service life.
Background technology
Chinese patent 95216796.4 discloses a kind of being used at vertical, the round Spiral spring cable that reaches on the slewing that moves of level, and its structure is that (center) is equipped with a helical spring steel wire in cable cover(ing).Though this core wire Spiral spring cable has with the moving and rotating of action parts, can not twine, tie a knot, the action of obstruction equipment.But this structural cable, because helical spring steel wire and insulated wire cores twist together, the invar silk has higher hardness, along with the frequent of cable moves or rotation, the core wire galling very easily occurs or pierces through insulating layer of conductor; Secondly, this version cable, especially when vertical the use, the stack of cable lower end discharges the twisting resistance that transmits above bearing, thus the twisting resistance maximum, therefore after the use several months, can be distorted distortion, bulge, break skin, until the heart yearn that fractures.These are not only easily accidents caused, cause cable short circuit or damage equipment; And cause cable useful life to shorten.Therefore still having is worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, providing a kind of both can satisfy vertical, level and come and go and move and the rotation occasion is used, the wire spring galling can not take place again or pierce through insulating layer of conductor, safe and reliable, the spring cable of long service life.
The utility model purpose realizes, the main improvement is that the helical spring steel wire is moved to cable periphery spiral inboard by the center, so both can guarantee the spring cable that forms, moving and rotate capable of expansion and contraction along with action component, can not twine, tie a knot, the action of obstruction equipment, can guarantee that again spring steel wire can not fray or pierce through insulating layer of conductor, fail safe is good.Specifically, the utility model spring cable comprises cable and attached to the composition of the spring steel wire on the cable, it is characterized in that said spring steel wire is attached to cable periphery spiral inboard.
Secondly, utility model is further to improve cable flexibility and fail safe, in each heart yearn slit of cable, adopt rubber to fill, said filling and cable cover(ing) once extrude and form, filling is integral with sheath like this, and when cable bore torsional moment, the unlikely generation displacement of each heart yearn caused distortion of the cable, when cable vertically used the lower end to bear big twisting resistance, the distortion that also can not be distorted, bulge, broken skin, heart yearn fractureed.
Utility model moves to cable periphery spiral inboard owing to will form the spring steel wire of Spiral spring cable by the center, spring steel wire and core distance have been widened, thereby guaranteed that effectively spring steel wire can not fray or pierce through insulating layer of conductor, the fail safe that has improved cable greatly; Secondly because spring steel wire in cable spiral inboard, can not influence normal use; Besides, adopt rubber to fill in each heart yearn slit, and with extrusion forming of sheath, make to fill to be integral with sheath, not only improved the flexibility of cable, and core good integrity, when cable bore torsional moment, the unlikely generation of each heart yearn displacement caused distortion of the cable, and when cable vertically uses the lower end to bear big twisting resistance, also can not be distorted distortion, bulge, broken skin, the heart yearn that fractures, thereby the fail safe that has improved cable greatly.
Below in conjunction with an embodiment, further specify utility model structure and advantage.
Description of drawings
Fig. 1 is a utility model Spiral spring cable structural representation.
Fig. 2 is a utility model Spiral spring cable cross section structure schematic diagram.
Embodiment
Embodiment: referring to accompanying drawing, Spiral spring cable 2, form the stranded stranding of conductor wire core by many conductors 6 outsourcing insulation rubbers 5, at cable periphery spring steel wire 3 in parallel, once extrude rubber 4 moulding, by specific purpose tool cable is made coil spring shape at last, and make the spring steel wire 1 that is coated with rubber insulation be positioned at the spiral inboard.
Utility model cable, its conductor radical can be any root as required.
The described cable of utility model comprises electric wire.
