Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to the anti-drag chain cable that circumnutates of a kind of industrial machine human, is used for power supply and signal control line that industrial robot moves the position.
Background technology
Drag chain cable with anti-gentle Qu Xiaoguo is widely used in the electrical source of power and control circuit of the frequent plant equipment that moves, particularly automated machine assembly line such as industrial robot.About industrial machine human drag chain cable, existing report in Chinese patent literature, the anti-robot drag chain cable that circumnutates typical as practical novel license notification number CN201126732Y provides, a plurality of insulated wire cores and reinforcement are twisted into cable core, outside cable core successively in conjunction with lapping layer, inner covering, screen and oversheath.The structure of CN201126731Y and the structural similarity of CN201126732Y.A kind of robot that CN201532802U recommends shield type warp resistance cable, it is that two-layer conductor is separated by twining package tape, the rubber filled core that contains the aramid fiber long filament is set in the central core of cable core, outside cable core, sets gradually lapping layer, screen, inner sheath and oversheath.The robot that CN201622874U discloses is with the three-dimensional property reversed flexible cable, by cable core be located at cable core lapping layer, inner covering, screen and restrictive coating outward successively and constitute.
The common strong point of the cable that above-mentioned patent scheme is related has good anti-circumnutating property, can be suitable for the frequent plant equipment that moves is that robot uses, but have common shortcoming: one, owing to the function singleness of cable causes in that to be applied to industrial machine man-hour installing space big, because above-mentioned patent is only as electric energy transmitting and can not the double as signal controlling, signal controlling needs corresponding signal controlling cable again; They are two years old, the whole flexibility of cable still can not show gratifying effect, and whether the quality of flexibility has determined anti-the circumnutating property of cable to a great extent, although CN201126732Y has instructed a plurality of insulated wire cores and reinforcement are twisted into cable core, but do not disclose rational twisting pitch, and reasonably twisting pitch ensures a key factor of cable flexibility just, prior art strand pitch determine to have blindness and subjective random; Its three, to squeezing the tensile strength be overlying on the outer insulating barrier of conductor and be positioned at the outmost restrictive coating of cable necessity of raising is arranged still because, if there is not desirable tensile strength, then be difficult to embody good travelling performance, finally influence the useful life of cable.
Summary of the invention
Task of the present utility model is that the signal control line that will provide a kind of energy will be used to introduce the power line of power supply and be used for signal controlling is gathered overall weight and the volume of using the minimizing cable in one and saved installing space; Help to promote flexibility and use and improve the anti-performance that circumnutates; Help improving tensile strength and use the anti-drag chain cable that circumnutates of industrial machine human that embodies excellent mobility and ensure the useful life of cable.
Task of the present utility model is finished like this, the anti-drag chain cable that circumnutates of a kind of industrial machine human, comprise cable core and be positioned at the outer separator of cable core successively, braid and oversheath, be characterised in that: described cable core comprises the power lead group and the same signal control line group of configuration in pairs of paired configuration, each power lead group comprises a pair of power lead core, overlayed on the outer power lead core coating of each power lead core and squeezed first sheath that protects outside power lead core coating, each signal control line group comprises a pair of signal controlling lead core, overlayed on the outer signal controlling lead core coating of each signal controlling lead core and squeezed second sheath that protects outside signal controlling lead core coating, wherein, the 7-10 pitch doubly of power lead group and the signal control line group outside diameter of cable after with stranding is stranded, and described first, second sheath and oversheath are polyester or polyurethane.
In a specific embodiment of the present utility model, described separator is a barrier paper.
In another specific embodiment of the present utility model, the width of described barrier paper is 30mm, and thickness is 0.04mm.
In another specific embodiment of the present utility model, described braid is made of zinc-plated thin copper wire braiding.
In another specific embodiment of the present utility model, described cable core also includes a ground wire.
The technical scheme that the utility model provides is owing to gather power lead group and signal control line group in same cable core, thereby can reduce the overall weight and the volume of cable and save installing space; Because the 7-10 pitch doubly of power lead group and the signal control line group outside diameter of cable after with stranding is stranded, thereby can make drag chain cable have the flexibility of excellence; Because first, second sheath and oversheath are adopted polyester or polyurethane, so tensile strength＞25MPa, can reach more than 5,000,000 times useful life.
Description of drawings
Fig. 1 is the cross sectional representation of example structure of the present utility model.
Embodiment
Ask for an interview Fig. 1, the anti-bent drag chain cable of the industrial machine human that the utility model scheme provides comprises cable core 1 and the separator 2 that is arranged on outside the cable core 1, separator 2 is a barrier paper, barrier paper preferably uses width to be 30mm, thickness is the barrier paper of 0.04mm, setting weaves the braid 3 that forms by the zinc-plated thin copper wire that diameter is preferably 0.1-0.3mm outside separator 2, by 3 shielding actions of braid, the technological means that adopts wires and cables industry generally to use outside braid 3 is squeezed the oversheath 4 of cover material material as polyester or polyurethane.
In order to make cable core 1 have excellent warp resistance performance, therefore doubly the pitch of (present embodiment is 8 times) is stranded with the 7-10 of the external diameter behind the stranding each other with aforesaid power lead group 11 and signal controlling lead group 12, and this pitch is the optimum range that draws after the applicant's repetition test.In addition because first, second sheath 113,123 and oversheath 4 have all used polyester or polyurethane, therefore the drag chain cable that obtains by the utility model scheme after tested tensile strength reached 25MPa, and can reach more than 5,000,000 times useful life.And, need not as prior art: will be used to provides the cable of power supply and is used to provide signal controlling to make respectively, be that the utility model scheme will be used for the cable of power supply being provided and providing the cable of signal controlling to gather in a cable, embodied the applicant at the technique effect described in the technique effect hurdle.
