Description
Technical field
The present invention relates to collector ring, especially a kind of multiconductor shell fragment collector ring.
Background technology
Traditional collector ring, is mainly made up of copper ring and the pressure carbon brush touched in copper ring outer round surface.There is following defect in the collector ring of this structure: one is complex structure, and carbon brush needs to be contained in carbon brush sleeve, and needs spring top pressure; Two is that wearing and tearing are very fast, needs often to change carbon brush; Three is there is hidden danger, and the carbon dust that carbon brush abrasion produces easily causes short circuit.
Summary of the invention
The object of the invention is to: provide a kind of multiconductor shell fragment collector ring, conduction is got an electric shock many, and resistance is little, and can prevent beating of metal clips in rotating operation process, good stability, and structure is simple, wear-resistant, safe and reliable.
For achieving the above object, the present invention can take following technical proposals:
A kind of multiconductor shell fragment of the present invention collector ring, comprise and be arranged on epitrochanterian becket, described becket is connected with epitrochanterian wire, the inner periphery of stator is evenly equipped with four insulation fixture blocks, also comprise multiple corrugated metal clips, each its two ends of described metal clips are fixedly arranged on adjacent two insulation fixture blocks respectively and it has at least one end to be connected with the wire on stator, and its trough pressure touches the outer round surface in described becket.
Each described insulation fixture block is equipped with the through hole of inclination, each described metal clips is arranged in this inclined via-hole corresponding.
Each described insulation fixture block is strip, arranges vertically, and described inclined via-hole has multiple and is distributed in vertically on corresponding insulation fixture block.
The cross section of each insulation fixture block is circular arc.
Separate by being fixedly arranged on epitrochanterian insulation ring plate between metal clips adjacent vertically.
Each described metal clips all has at least two troughs.
Described multiconductor shell fragment collector ring is arranged under water in numerical control nozzle, and the lower end of stator is by being arranged on lower oil sealing on stator bottom end cover and rotor forms water-stop, and the upper end of stator is by being arranged on upper oil sealing on stator upper end cover and rotor forms water-stop.
The edge of this stator bottom end cover between stator and stator bottom end cover is provided with lug, described lug is provided with wire perforation, the inner port capping of boring a hole at described wire has one piece of cover plate, the inner side of described cover plate is welded with inner lead, this inner lead is the wire on described stator, the outside of cover plate is welded with outer lead, and described inner lead is connected by the conductor correspondence on cover plate with outer lead, is filled with fluid sealant in the wire perforation outside described cover plate.
Described cover plate is printed substrate, conductor on described cover plate is the printed wire on printed substrate, this printed substrate is fixed in the inner port of wire perforation by fixed screw, and described inner port place is provided with groove, and described printed substrate is embedded in this groove.
Compared with prior art the invention has the beneficial effects as follows: owing to adopting technique scheme, the inner periphery of stator is evenly equipped with four insulation fixture blocks, also comprise multiple corrugated metal clips, each its two ends of described metal clips are fixedly arranged on adjacent two insulation fixture blocks respectively and it has at least one end to be connected with the wire on stator, its trough pressure touches the outer round surface in described becket, this structure, simpler than traditional carbon brush structure, and metal clips resistance to wear is better, metal clips two ends are fixedly arranged on two adjacent insulation fixture blocks, beating of metal clips in rotating operation process can be prevented, contact point is more stable, conducting effect is better.
Further beneficial effect is: the trough of metal clips all has two two or more, can strengthen contact area like this, improve conducting effect further.
Further beneficial effect is: traditional conductor leading Sealing Technology, inside cable is generally all adopted to weld or hinge joint, wrap up in insulating tape or heat-shrink tube, it is swollen that cable sealing O type circle makes it squeeze by pressure, by cable sheath press seal, this structure, can accomplish waterproof action really, but hermetically-sealed construction inner chamber and external environment condition still communicate, because in, the inner many bare copper wires of external cable line multiple conducting wires and each root wire or UNICOM, the inner electrical equipment of the hermetically-sealed construction that this stops for working for a moment for a moment, be in the state of a cold heat, be easy to form dew condensation phenomenon in inside, make hermetically-sealed construction inside produce aqueous vapor and cause the device damage such as electrical equipment.And cable joint is because be stained with aqueous vapor and the reason of energising, through oxide etch after a while, also can produce oxidation breaking phenomena, cause the device damage in hermetically-sealed construction normally to use.The principle that condensation produces: for submersible machine and light fixture.Motor or light fixture are when indoor assembling completes, in inner chamber, relative humidity is at 40-50%, when motor runs, high temperature can be produced in inner space, the air bulbs of pressure become large, because equilibrium principle, gas pressure in cavity increases, need to overflow outward to reach internal and external pressure balance, at this moment, because in, the inner many bare copper wires of external cable line multiple conducting wires and each root wire or UNICOM, gas will overflow, inner and outer air pressure is until balance, simultaneously because interior cavity temperature raises, the relative humidity of air declines, such as drop to 10%, in order to inside and outside wetting balance can be reached, at the edge of rubber seal water, the place of cable adapter, what water can evaporate quickly (can become dry) at once, increase the absolute magnitude of steam, the relative humidity in chamber and the external world is made to reach balance.When light fixture or motor do not run, to such an extent as to cavity temperature cooling, a negative pressure can be formed in chamber, so extraneous malaria flows in cavity, and the state of the relative humidity balance reached because temperature raises in original chamber, because temperature cooling is broken, cooling makes relative humidity in chamber become suddenly large, when exceeding saturated or encounter colder material, just there is condensation.The edge of this stator bottom end cover of the present invention between stator and stator bottom end cover is provided with lug, described lug is provided with wire perforation, the inner port capping of boring a hole at described wire has one piece of cover plate, the inner side of described cover plate is welded with inner lead, this inner lead is the wire on described stator, the outside of cover plate is welded with outer lead, described inner lead is connected by the conductor correspondence on cover plate with outer lead, fluid sealant is filled with in wire perforation outside described cover plate, this structure, fluid sealant can not only be utilized wire aperture seal, and due to interior, external cable line is connected by the conductor correspondence on cover plate, in this just makes, outer lead multiple conducting wires and wire inside many bare copper wires are also separated by a seal, make closed structure inner chamber and the external world completely isolated, this has just stopped the circulation of closed structure inner air and outer air, inner air and outer air can not produce circulation, steam just cannot enter closed structure inner chamber, the dew condensation phenomenon of closed structure inside just cannot be formed, good sealing effect, lasting stability.And achieving the hermetically-sealed construction that conductor leading is set at stator and stator bottom end cover narrow space, structure is simple, compact, and occupy-place is little, good sealing effect, solves the technical barrier of music spring system conductor leading sealing under water.
