Description
Technical field
This utility model relates to the waterproof anticreep field of electrical connection, the sealing structure of a kind of electric connector.
Background technology
Along with the extensive application of electric power, increasing position need electric power as the source of the energy, particularly at some
Special working environment, electric power use there is special convenience and operability；And connection skill the most waterproof, anti-creeping
Art, uses and is wound around the mode Integral sealing such as insulating tape, gluing after connecting, use loaded down with trivial details, it is necessary to link airtight before entering water.?
Such as connect in the environment of colliery, gas station, gas station etc. are inflammable and explosive and may explode by generation spark, dangerous.Cause
This, existing electrical appliance yet suffers from following deficiency in interconnection technique: 1. pair airtight deficiency of connecting portion integral sealing；2. use
Loaded down with trivial details, difficult in maintenance, some the most disposably connects；3. can not hot line job in water or in conducting medium.
Now in electric connector, often there is many encapsulants, but, existing encapsulant cannot meet
The requirement of sealing function, encapsulant causes underlying reason is that of leakage to seal the pressure differential inside and outside position or concentration official post
Fluid flows, and has gap on sealing surface, makes fluid overflow.For different types of sealing, action principle is different.Quiet
Seal and be dependent on closing the gap between faying face to realize sealing function；And movable sealing cannot rely on merely between closing faying face
Gap realize sealing because gap is tightr, the frictional resistance during relative motion of antithesis surface is the biggest, causes faying face to be sent out
Heat, makes sealing be quickly invalidated, and therefore movable sealing action principle is characterized by and both can keep sealing and don't produce bigger friction resistance
Power, including reducing the pressure differential sealing both sides and making to keep between faying face fluid lubrication film etc..
Utility model content
Utility model purpose of the present utility model is: for the problem of above-mentioned existence, it is provided that a kind of electric connector close
Seal structure, utilizes and forms multiple reduced pressure zone at the sealing of electric connector, reduces conducting medium and answers pressure reduction to reveal；With
The combination in gap and conducting medium that Shi Liyong is in sealing contact place produces water-stop effect；Reduce the contact surface sealed, it is possible to anti-
In the case of only encapsulant deforms under stress situations, produce fold at the place of being in sealing contact because pressure is uneven and is formed
Gap, causes the situation that conducting medium penetrates into；Utilize the setting of cavity and utilize air in cavity flow conductivity, make at sealing
Pressure uniform, improve sealing effectiveness.
