Description
Technical field
The present invention relates to a kind of direct current closed type contactor, more particularly to a kind of encapsulation knot of direct current closed type contactor
Structure.
Background technology
The encapsulating structure of existing direct current closed type contactor is to use epoxy resin cup-shaped into a seal cavity with iron,
Seal cavity inside includes coil block etc..Because the internal environment requirement of seal cavity is relatively outside more clean, so
Can guarantee that the performance of sealed product.But the coil of existing direct current closed type contactor is sealed in inside cavity, due to line
Circle is made up of enamel-covered wire, and the enamel-covered wire work regular hour can generate heat, and such enamel-covered wire will give out necessarily has pollution
Gas so that coil block forms pollution sources maximum in seal cavity, so as to influence the performance of D.C. contactor.
The content of the invention
In order to overcome drawbacks described above, the invention provides a kind of encapsulating structure of direct current closed type contactor, by coil group
Part is arranged on outside the seal cavity that epoxy resin is formed with cup, so that effective isolate pollution sources from the inner space of cavity
Out, the performance of sealed product is improved.
The technical scheme that is used to solve its technical problem of the present invention is：A kind of encapsulation of direct current closed type contactor
Structure, including both ends open shell body, the bottom port of the shell body is provided with bottom end cover, and iron cup group is provided with the shell body
Part and coil block, the iron cup assembly include forming the annular seal space for installing each component of the contactor in addition to coil block
The iron cup housing of body and the inner support frame in iron cup housing upper port, are fixed with a butted line on the inner support frame
Post, in sealing contact between the middle part of the iron cup housing and the shell body, the radius of the bottom of the iron cup housing reduces
And coil installing space for installing the coil block is formed between the shell body；The lateral surface of the inner support frame
Epoxy resin is equipped with space between the upper end periphery of the upper and iron cup housing and the shell body, the asphalt mixtures modified by epoxy resin
Fat will form a seal cavity between iron cup housing and inner support frame.
As a further improvement on the present invention, the bottom of the iron cup framework is cylinder, the line of the coil block
Ring box is set up in the bottom outside of the iron cup framework, and the coil of the coil block is wound on the magazine.
As a further improvement on the present invention, the inside middle portion of the shell body is inwardly convexly equipped with engaging side, the engaging side
In sealing contact with iron cup housing, the epoxy resin is at least encapsulated to the engaging side position.
As a further improvement on the present invention, the engaging upper port center side of the side towards the shell body of the shell body
To inclination.
As a further improvement on the present invention, the upper port of the shell body is externally provided with upper end positioned at the epoxy resin
Lid.
The beneficial effects of the invention are as follows：The encapsulating structure of the direct current closed type contactor passes through epoxy resin by iron cup assembly
Iron cup housing seal the other assemblies to be formed for installing contactor in addition to coil block, so as to by coil block from inside it is close
Envelope cavity is isolated, and effectively pollution source coil can be so isolated from seal cavity, is mitigated in seal cavity
The pollution of environment, so as to improve the performance of sealed product.In addition, the present invention can also save content of epoxy resin, epoxy resin
Only need to that the part of iron cup housing is packaged the effect that can reach sealing.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
With reference to accompanying drawing, make the following instructions：
1 --- shell body 2 --- iron cup assembly
3 --- coil block 4 --- bottom end covers
5 --- iron cup housing 6 --- inner support frames
7 --- binding posts 8 --- engage side
9 --- upper end cover 10 --- epoxy resin
Specific embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the invention is elaborated.But protection scope of the present invention is not
Be limited to following embodiments, i.e., the simple equivalence changes made with scope of the present invention patent and description in every case with repair
Decorations, all still belong within patent covering scope of the present invention.
Refering to the encapsulating structure that Fig. 1 is a kind of direct current closed type contactor of the present invention, including both ends open is outer
Housing 1, the bottom port of the shell body is provided with bottom end cover 4, and iron cup assembly 2 and coil block 3, iron cup assembly are provided with shell body
It is used to install the iron cup housing 5 of the seal cavity of each component of the contactor in addition to coil block including formation and located at iron cup
Inner support frame 6 in housing upper port, is fixed with a pairs of posts 7, the middle part of iron cup housing and shell body on inner support frame
Between it is in sealing contact, the radius of the bottom of iron cup housing reduces and line for installing coil block is formed between shell body
Circle installing space；On the lateral surface of inner support frame and iron cup housing upper end periphery and shell body between space in be all provided with
There is epoxy resin, the epoxy resin will form a seal cavity between iron cup housing and inner support frame.
Wherein, the bottom of the iron cup framework is cylinder, and the magazine of coil block is under iron cup framework
End outside, the coil of coil block is wound on magazine.The inside middle portion of shell body is inwardly convexly equipped with engaging side 8, should
Engaging side is in sealing contact with iron cup housing, and epoxy resin is at least encapsulated to the engaging side position, that is, engage planar shaped where side
Into the encapsulation boundary line of epoxy resin.
Preferably, the engaging side of the shell body inclines towards the upper port center position of the shell body, the shell
The upper port of body is externally provided with upper end cover 9 positioned at the epoxy resin.
It can be seen that, the encapsulating structure of the direct current closed type contactor is sealed the iron cup housing of iron cup assembly by epoxy resin
The other assemblies for installing contactor in addition to coil block are formed, so as to coil block be isolated from inner sealing cavity
Come, effectively pollution source coil can be so isolated from seal cavity, mitigate the pollution of annular seal space vivo environment, from
And improve the performance of sealed product.In addition, the present invention can also save content of epoxy resin, epoxy resin only needs to iron cup is outer
The part of frame is packaged the effect that can reach sealing.
