The utility model content
The technical problems to be solved in the utility model is, a kind of servomotor cable that is integrated with power line and encoder feedback line is provided.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of servomotor cable, comprise oversheath and be arranged on described oversheath interior power line and encoder feedback line, described power line and described encoder feedback line combination stranding, described power line or described encoder feedback line comprise heart yearn and are coated on successively insulating barrier and the gauze screen in the described heart yearn outside, the gauze screen outside of described power line is coated with inner sheath, the outside of described inner sheath is coated with the first screen, described servomotor cable also comprises the secondary shielding layer, described secondary shielding layer is coated on described power line and the described encoder feedback line outside, and described oversheath is coated on the described secondary shielding layer outside.
In servomotor cable described in the utility model, described heart yearn is formed by annealing oxygen-free copper tow strand.
In servomotor cable described in the utility model, described insulating barrier is extruded in the described heart yearn outside by the PVC material.
In servomotor cable described in the utility model, described gauze screen is worked out by tinned copper wire.
In servomotor cable described in the utility model, described inner sheath is PVC armour formula sheath.
In servomotor cable described in the utility model, described the first screen comprises aluminium foil and wrapped tinned copper wire mesh grid in the described aluminium foil outside.
In servomotor cable described in the utility model, described secondary shielding layer comprises aluminium foil and wrapped tinned copper wire mesh grid in the described aluminium foil outside.
In servomotor cable described in the utility model, described encoder feedback line is provided with many, is filled with aramid fiber yarn in the gap between many described encoder feedback lines.
In servomotor cable described in the utility model, described oversheath is made by the PUR material.
Implement servomotor cable of the present utility model, have following beneficial effect: power line and encoder feedback line combination stranding are integrated in the oversheath, dwindled the volume of cable, make things convenient for the cable cable laying operation, also reduced production process, saved production cost.Power line is coated with the first screen; can stop power line to the interference of encoder feedback line; be coated with again the secondary shielding layer in the outside behind power line and the encoder feedback line combination stranding; can stop external electromagnetic waves to the interference of encoder feedback line; the first screen and secondary shielding layer can effectively be protected the encoder feedback line, and code device signal can not be interfered.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model servomotor cable.
Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, servomotor cable of the present utility model comprises power line 2, encoder feedback line 3, inner sheath 4, oversheath 1, the first screen 5 and secondary shielding layer 6.
Wherein, power line 2 comprises heart yearn, insulating barrier and gauze screen, and insulating barrier and gauze screen are coated on the outside of heart yearn successively.Insulating barrier is wrapped in the heart yearn outside, plays the effect of insulation protection.Gauze screen plays the effect of shielding protection, tentatively avoids electromagnetic wave that it is produced and disturbs, and can prevent that also the electromagnetic wave in the heart yearn from leaking.The outside at gauze screen also is coated with inner sheath 4.Inner sheath 4 in the present embodiment is PVC(Poly Vinyl Chloride, polyvinyl chloride) armour formula sheath, be wrapped in the outside of gauze screen by the PVC material by the mode of armour formula extrusion modling, inner sheath 4 tear-proof, anti-cutting have strengthened the ability of antagonism mechanical stress.The first screen 5 is coated on the outside of inner sheath 4, the interference that can stop 2 pairs of encoder feedback lines 3 of power line.4 power lines 2 are arranged in the present embodiment, coat again the first screen 5 after the many power line 2 bundle strands.
Encoder feedback line 3 comprises heart yearn, insulating barrier and gauze screen, and insulating barrier and gauze screen are coated on the outside of heart yearn successively.Insulating barrier is wrapped in the heart yearn outside, plays the effect of insulation protection.Gauze screen plays the effect of shielding protection, tentatively avoids electromagnetic wave that it is produced and disturbs, and can prevent that also the electromagnetic wave in the heart yearn from leaking.Behind encoder feedback line 3 and the power line 2 combination strandings, secondary shielding layer 6 is coated on the outside, can stops external electromagnetic waves to the interference of encoder feedback line 3.Oversheath 1 is coated on power line 2 and encoder feedback line 3 outsides, plays the effect of further protection, avoids mechanical damage or chemical corrosion.Oversheath 1 in the present embodiment is by PUR(polyurethane) the material extrusion modling makes, guarantee to be not less than 1,000 ten thousand times the life-span that deflects, and oil resistance is good.Encoder feedback line 3 in the present embodiment has 14, be common to various encoders, has reduced the probability that the user falsely drops misuse.
Further, the heart yearn in encoder feedback line 3 or the power line 2 is formed by annealing oxygen-free copper tow strand, and elongation and resistivity properties are good.
