Description
Technical field
This utility model is related to a kind of instrument waterproof construction, and in particular to a kind of instrument structure of IP68 degree of protection.
Background technology
The barrier propterty and degree of protection of panel instrument is an important indicator of instrument design.When instrument and meter is in one
In the individual closed environment filled with certain air, when temperature is raised, gas expansion, when instrument housing inner and outer air pressure is fastened more than housing
During power, gas can be extruded from sealing；In the same manner, when temperature is reduced, contraction of gas, when the outer interior air pressure of housing exceedes housing fastening force
When, gas and extraneous steam can be penetrated into from housing seal；Several times repeatedly after, although gas can be passed in and out, steam only enters not
Go out.Instrument is affected by ambient temperature, and inside repeatedly enters steam, and stemming moisture accumulation can affect instrument internal electricity to a certain amount of
Line structure, causes instrument service behaviour to reduce even damaging.
For the electronic instrument for needing IP67 degree of protection, in addition to necessary sealing, can also be using in instrument housing
It is upper that two-way ventilative, the pressure balance vent valve of Unidirectional water permeable vapour is installed, carry out the pressure of balance shell inside and outside and intercept steam to enter
Housing；But if this instrument needs to duck in drink for a long time, and ambient temperature is when changing greatly, and is only breathed freely by installing pressure balance
Valve, when there's a sudden fall in temperature, steam can be by, at sealing, making a forcible entry into enclosure interior, cannot still play protective action.Therefore,
The degree of protection of IP68 is reached, that is, reaches the purpose that equipment can soak for a long time, in addition to reducing confined space, in addition it is also necessary to right
Enclosure interior carries out fill sealing process, makes to fill sealing, encapsulating in space of the enclosure interior in addition to some particular devices
When not only to be ensured that the instrument after encapsulating has good protection effect, to also avoid LCD display portions and infrared electro joint
Glue is touched Deng part and its performance is affected.
In addition, the IP68 degree of protection in order to reach instrumentation, not only it is noted that preventing to discrete housing parts
Shield process, in addition it is also necessary to be fixed design to the cable through housing, ties to the sealing of internal encapsulating during preventing cable from loosening
Structure produces destruction.
