Description
Technical field
The present invention relates to a kind of hermetically-sealed construction, the structure that especially wire of drawing in the closed structure or introducing is sealed.
Background technology
In many occasions, need to from hermetically-sealed construction, draw wire or in the hermetically-sealed construction lead-in conductor, this just need to seal conductor leading.Traditional conductor leading Sealing Technology, generally all adopt inside cable welding or hinge joint, wrap up in insulating tape or heat-shrink tube, it is swollen that cable squeezes it with sealing O type circle by pressure, with the 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 is in the state of a cold heat, be easy to and form the condensation phenomenon in inside, make the inner aqueous vapor that produces of hermetically-sealed construction cause the device damage such as electrical equipment.And cable joint through oxide etch after a while, also can produce the oxidation breaking phenomena because be stained with the reason of aqueous vapor and energising, causes the device damage in the hermetically-sealed construction normally to use.
The principle that condensation produces: take submersible machine and light fixture as example.When motor or light fixture are finished in indoor assembling, relative humidity is in 40-50% the inner chamber, when motor moves, can produce high temperature in the inner space, it is large that the air bulbs of pressure become, because equilibrium principle, the gas pressure in the cavity increases, need to overflow outward and 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, because interior cavity temperature raises, the relative humidity of air descends, such as dropping to 10% simultaneously, in order to reach inside and outside wetting balance, at the edge of rubber seal water, the place of cable adapter, very fast (can become dry) that water can evaporate at once, increase the absolute magnitude of steam, make relative humidity and the external world in the chamber can reach balance.When light fixture or motor do not move, to such an extent as to cavity temperature cooling, can in the chamber, form a negative pressure, so extraneous malaria flows in the cavity, and the state of the relative humidity balance that reaches because temperature raises in the original chamber, because the temperature cooling is broken, cooling makes suddenly change of relative humidity greatly in the chamber in, when surpassing when saturated or running into colder material, condensation just occurs.
Summary of the invention
The object of the invention is to: the hermetically-sealed construction of conductor leading in a kind of closed structure is provided, and it is simple in structure, and the installation occupy-place is little, easy-to-connect, good sealing effect, lasting stability.
For achieving the above object, the present invention can take following technical proposals:
The hermetically-sealed construction of conductor leading in a kind of closed structure of the present invention, comprise a wire perforation that connects with described closed structure, inner port capping in described wire perforation has a cover plate, the inboard of described cover plate is welded with inner lead, the outside of cover plate is welded with outer lead, described inner lead is connected corresponding connection of conductor on the cover plate with outer lead, be filled with fluid sealant in the wire perforation in the described cover plate outside.
Described cover plate is printed substrate, and the conductor on the described cover plate is the printed wire on the printed substrate, and this printed substrate is fixed on the inner port of wire perforation by fixed screw.
Described inner port place is provided with groove, and described printed substrate is embedded in this groove.
Described hermetically-sealed construction is the underwater sealing collector ring, and described wire perforation is arranged on the lug, and described lug is on the edge of this collector ring stator bottom end cover between collector ring stator and the collector ring stator bottom end cover.
Described hermetically-sealed construction is the underwater sealing collector ring, and described wire perforation is arranged on the lug, and described lug is arranged on the collector ring rotor.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme, be provided with the wire perforation that connects closed structure, inner port capping in described wire perforation has a cover plate, the inboard of described cover plate is welded with inner lead, the outside of cover plate is welded with outer lead, described inner lead is connected corresponding connection of conductor on the cover plate with outer lead, in the wire perforation in the described cover plate outside, be filled with fluid sealant, this structure, not only can utilize fluid sealant with the wire aperture seal, and because in, outer lead is to connect by the conductor on the cover plate is corresponding, this just so that in, the inner many bare copper wires of outside multiple conducting wires and wire are also separated by a seal, make closed structure inner chamber and the external world fully isolated, this has just stopped the circulation of closed structure inner air and outer air, and inner air and outer air can not produce circulation, steam just can't enter the closed structure inner chamber, the condensation phenomenon of closed structure inside just can't form, good sealing effect, lasting stability.
Further beneficial effect is: described hermetically-sealed construction is the underwater sealing collector ring, described wire perforation is arranged on the lug, described lug is on the edge of this collector ring stator bottom end cover between collector ring stator and the collector ring stator bottom end cover, this structure, realized arranging at collector ring stator and collector ring stator bottom end cover narrow space the hermetically-sealed construction of conductor leading, this hermetically-sealed construction, simple in structure, compact, occupy-place is little, good sealing effect has solved the technical barrier of music spring system conductor leading sealing under water.
