Description
The application is filing date on July 25th, 2013, and Application No. 201310314654.7 is invention entitled " airtight
The sealing structure of conductor leading in structure " divisional application.
Technical field
The present invention relates to a kind of sealing structure, the knot especially wire drawn in closed structure or introduce sealed
Structure.
Background technology
In many occasions, need from sealing structure, draw wire or to sealing lead-in conductor in structure, this is accomplished by right
Conductor leading seals.Traditional conductor leading Sealing Technology, the most all uses inside cable welding or hinge joint, wraps up in insulation
Adhesive plaster or heat-shrink tube, it is swollen that cable sealing O makes it squeeze by pressure, is compressed by cable sheath and seals, this structure,
Can accomplish waterproof action really, but seal structure inner chamber and external environment condition still communicates, because inside and outside portion cable is many
Root wire and the internal many bare copper wires of each wire or UNICOM, this sealing structure for a moment stopped for working for a moment
For internal electrical equipment, it is in the state of a cold heat, it is easy to dew condensation phenomenon can be internally formed, make sealing inside configuration produce
Aqueous vapor causes the device damage such as electrical equipment.And cable connector is because be stained with aqueous vapor and the reason being energized, through after a while
Oxide etch, also can produce oxidation breaking phenomena, causes the device damage sealed in structure normally to use.
The principle that condensation produces: as a example by 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, can produce high temperature in inner space, and air expansion pressure becomes big, because balance
Principle, the gas pressure in cavity increases, needs to overflow outward to reach internal and external pressure balance, at this moment, because inside and outside portion cable
Multiple conducting wires and the internal many bare copper wires of each wire or UNICOM, gas will overflow, inner and outer air pressure until balance,
Simultaneously as interior cavity temperature raises, the relative humidity of air declines, and such as drops to 10%, puts down to be able to reach inside and outside humidity
Weighing apparatus, at the edge of rubber seal water, the place of cable adapter, very fast (at once can become dry) that water can evaporate, increase water and steam
The absolute magnitude of gas, makes the relative humidity of intracavity and the external world can reach balance.When light fixture or motor do not run, to such an extent as to intracavity temperature
Degree cooling, meeting forms a negative pressure at intracavity, and then extraneous malaria flows in cavity, and original intracavity is because of temperature liter
The state that relative humidity that is high and that reach balances, because temperature cooling is broken, cooling makes intracavity relative humidity become suddenly big, when
When exceeding saturated or encounter colder material, just there is condensation.
Summary of the invention
It is an object of the invention to: the sealing structure of conductor leading in a kind of closed structure, its simple in construction are provided, install
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: conductor leading in one closed structure of the present invention
Sealing structure, including through with a described closed structure wire perforation, the inner port capping bored a hole at described wire has one
Block cover plate, the inner side of described cover plate is welded with inner lead, and the outside of cover plate is welded with outer lead, and described inner lead is with outer
Portion's wire is connected by the conductor correspondence on cover plate, is filled with fluid sealant in the wire perforation outside described cover plate.
Described cover plate is printed substrate, and the conductor on described cover plate is the printed wire on printed substrate, this printing
Wiring board is fixed in the inner port of wire perforation by fixed screw.
Being provided with groove at described inner port, described printed substrate is embedded in this groove.
Described sealing structure is underwater sealing collector ring, and the perforation of described wire is arranged on lug, and described lug is positioned at collection
On the edge of this collector ring stator bottom end cover between electricity ring stator and collector ring stator bottom end cover.
Described sealing structure is underwater sealing collector ring, and the perforation of described wire is arranged on lug, and described lug is arranged at
On collector ring rotor.
Compared with prior art the invention has the beneficial effects as follows: owing to using technique scheme, be provided with through airtight
The wire perforation of structure, the inner port capping bored a hole at described wire has one piece of cover plate, and the inner side of described cover plate is welded with inside
Wire, the outside of cover plate is welded with outer lead, described inner lead and outer lead and connects by the conductor on cover plate is corresponding,
It is filled with fluid sealant, this structure in wire perforation outside described cover plate, fluid sealant can not only be utilized to be bored a hole by wire
Seal, and owing to inside and outside portion wire is to be connected by conductor correspondence on cover plate, this allow for inside and outside portion multiple conducting wires with
And the internal many bare copper wires of wire are the most separated by a seal, make closed structure inner chamber and the external world completely cut off completely, this has just stopped airtight
The circulation of structure inner air and outer air, inner air and outer air can not produce circulation, and steam cannot propagate into closed structure inner chamber, closed structure
Internal dew condensation phenomenon just cannot be formed, good sealing effect, lasting stability.
Further providing the benefit that: described sealing structure is underwater sealing collector ring, the perforation of described wire is arranged at convex
On ear, the edge of the described lug this collector ring stator bottom end cover between collector ring stator and collector ring stator bottom end cover
On, this structure, it is achieved that the sealing of conductor leading is set at collector ring stator and collector ring stator bottom end cover narrow space
Structure, this sealing structure, simple in construction, compact, occupy-place is little, good sealing effect, solves music spring system wire under water
The technical barrier that lead-in wire seals.
