Abstract
The utility model provides a kind of connector, is used in filter and is structure as a whole with the shell of filter.The connector includes the external screw thread for being located at periphery, if the through-hole communicated in its center and with the inside of filter, internally positioned inner surface and set inside it, close to the through-hole middle part anti-decylization.The anti-decylization is made of the inclination annulus that the inclined direction and tilt angle of a vertical annulus and an inclined direction and tilt angle and the second contact surface of nut match.Two sealing surfaces are formed when the connector is connect with the screw cap closures, one be the inner surface and the nut the primary sealing area that is formed of the first contact surface, the other is the secondary sealing area that the second contact surface of the anti-decylization and the nut is formed.Under the filtering operating condition of negative pressure, the secondary sealing area can prevent the inner surface of the first contact surface disengaging connector of nut, and the inclination annulus of anti-decylization can prevent nut from being detached from connector.
Description
Technical field
The utility model relates to a kind of connectors for filter, more particularly to one kind also can under negative pressure filtration operating condition
The connector of good sealing property is kept with nut, and then guarantees the good exhaust performance of filter and strainability.
Background technique
Liquid crystal is very important material in photoelectric display technology, and cleanliness has weight to the display performance of electronic component
It influences.For the purity requirements for meeting electronics industry manufacture, needs to be filtered liquid crystal before use, remove wherein included
Impurity.The top of the existing filter housing for liquid crystal filtering is equipped with mesogen feed liquid port, and outer casing bottom is equipped with cleaning
Liquid crystal exports, and is equipped with exhaust outlet close to top on side wall of outer shell, and filter core is located at filter interior, filter core upper end and filter housing
Top is connected to there are a gas storage space with exhaust outlet, with easy to exhaust.When filtering, generally by adding at filter inlet
The mode of pressure is by liquid crystal filling to filter interior or will be in liquid crystal filter by suction by the way of filter interior negative pressure
Portion.But existing filter is when using the feeding manner of filter interior negative pressure, it may appear that the connector on filter housing
The phenomenon that being detached from the sealing surface of nut.The leakproofness decline of filter is thereby resulted in, the exhaust performance decline of filter causes
The gas volume for being trapped in filter interior increases, and liquid crystal to be filtered is difficult to enter back into filter interior, filter interior
The liquid level of liquid crystal declines, and bubble is attached to filter membrane surface and generates air-resistance phenomenon, the decline of filter membrane effective filtration area, the mistake of filter
Performance decline is filtered, and is easy to appear the phenomenon that bubble reaches downstream electronic element with clean liquid crystal, causes imaging defect.
Accordingly, it is desirable to provide a kind of connector that can also keep good sealing property with nut under negative pressure filtration operating condition, comes
The exhausting problem of filter is solved, and improves the strainability of filter.
Summary of the invention
To solve the exhausting problem of filter and improving the strainability of filter, the utility model provides one kind and was used for
The connector of filter.The connector also can keep good leakproofness with nut under negative pressure filtration operating condition, so that it is guaranteed that filter
Good exhaust performance and normal feed liquor, provide effective filtering.
Connector provided by the utility model, is an integral structure with filter housing.
The connector includes the external screw thread for being located at periphery, the through-hole for being located at center and communicating with the inside of filter, position
In the inner the inner surface in portion and set inside it, close to the through-hole middle part anti-decylization.
The connector is tightly connected by the internal screw thread of the external screw thread and nut.
The nut has the first contact surface and the second contact surface that two sealing surfaces are formed with the connector.
The anti-decylization is an integral structure with the connector, by a vertical annulus and an inclined direction
The inclination annulus to match with the inclined direction and tilt angle of tilt angle and the second contact surface of the nut is constituted.
When the connector is connect with the screw cap closures, two sealing surfaces are formed with the nut, one is institute
The primary sealing area that first contact surface of the inner surface for the connector stated and the nut is formed, the other is the anti-decylization
The secondary sealing area formed with the second contact surface of the nut.
Connector in the prior art only forms a sealing surface with nut, i.e., connector is interior due to not having anti-decylization
The primary sealing area that first contact surface of surface and nut is formed, under negative pressure filtration operating condition, be easy to appear nut first is connect
Contacting surface is detached from the problem of inner surface of connector, causes the leakproofness of filter to decline, so as to cause filter exhaust and filterability
It can decline, influence the quality of liquid crystal.Compared with prior art, connector provided by the utility model and nut can be additionally formed one
The secondary sealing area that second contact surface of a sealing surface, i.e. anti-decylization and nut is formed.Under the filtering operating condition of negative pressure, anti-decylization
The secondary sealing area formed with the second contact surface of nut can prevent the first contact surface of nut from being detached from the inner surface of connector, prevent
The inclination annulus of decylization can prevent nut from being detached from connector, thus connector and nut are also able to maintain well under negative pressure filtration operating condition
Leakproofness, guarantee that filter can reach normal liquid level inside normal feed liquor and filter cylinder, and then ensure filter
Good exhaust and strainability.
