There is clad, the clad is cured organic casting glue.
Further, the clad is the organic casting glue of cured two-component.
Further, the upper housing or lower case offer fitting groove, and the electronic system is assemblied in fitting groove, institute
It states gypsum obturator to be filled in fitting groove, the clad coats the outer surface of exposed gypsum obturator.
By technical solution provided by the utility model, have the following beneficial effects:
It first passes through the filling of gypsum obturator and coats the electronic system, the gypsum material of gypsum obturator is at low cost, market
It is easy to get, safety is good and is easy to modulate the advantage of processing；Mechanical irrigation sealing is coated in the outer surface of gypsum obturator again
Clad, overall sealing structure can reach the requirement of IEC61215 standard, and sealing grade reaches IP68, meets sealing demand, produces
Product airtight quality is guaranteed.This kind of structure can reduce by 1 yuan compared with the prior art, cost, be allowed to more competing for market
Strive advantage.
It is by gypsum raw material (CaSO meanwhile using gypsum obturator4.4H2O after) being let down in proportion with diluent, encapsulating
In solidification in terminal box into (step is the prior art), the solidified forming time of the structure of this programme has compared with conventional two-component
The curing time of machine silicon casting glue is short, and production efficiency can be improved；And by adjusting the proportion of gypsum raw material and diluent
So that the curing time of gypsum is controllable, can more accurately grasp.
Detailed description of the invention

A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
It is shown in reference picture 1, Fig. 2, a kind of terminal box of solar cell module provided in this embodiment, including box body 10 with
And it is integrated in the intracorporal electronic system 21 of the box, the box body 10 is equipped with terminals 22 and is electrically connected the electronic system 21；
Filler plaster obturator 30 in the box body 10, the gypsum obturator 30 coat the electronic system 21, the gypsum filling
The outer surface of body 30 is coated with coating layer 40, and the clad 40 is cured organic casting glue.
This programme first passes through the filling of gypsum obturator 30 and coats the electronic system 21, the gypsum material of gypsum obturator 30
At low cost, market is easy to get, safety is got well and is easy to modulate the advantage of processing；It is coated again in the outer surface of gypsum obturator 30
The clad 40 of organic casting glue, overall sealing structure can reach the requirement of IEC61215 standard, and sealing grade reaches IP68, accords with
Sealing demand is closed, product airtight quality is guaranteed.This kind of structure can reduce by 1 yuan, be allowed to compared with the prior art, cost
More for market competition advantage.
It is by existing gypsum raw material (CaSO meanwhile using gypsum obturator 304.4H2O it) is let down in proportion with diluent
Afterwards, in solidification in terminal box 10 into (step is the prior art), the solidified forming time of the structure of this programme is more normal for encapsulating
The curing time for advising bi-component organic silicon casting glue is short, and production efficiency can be improved；And by adjusting gypsum raw material with it is dilute
