Cable passage is stretched in described accommodating cavity and electrically connected with described operating circuit module, and described line card has multiple cards
Muscle, described line card fix connection cables in cable passage through described fixation passage, are filled in described accommodating cavity
There is the second colloidal silica with insulating radiation performance, the second described colloidal silica is completely coated in operating circuit module.
According to further improvement of the present invention, the first described colloidal silica is single component silica gel, and the second colloidal silica is double groups
Divide silica gel.
According to further improvement of the present invention, there is space, the second described silicon between each card muscle of described line card
Colloid is flowed into form cable passage in the space by cable passage and sealed.
According to further improvement of the present invention, described cable passage is shaped in described wiring box body, described
Fixation passage be arranged on the back side of described wiring box body.
By adopting the above-described technical solution, it is not difficult to find out that full encapsulating photovoltaic component terminal box of the invention connects compared to tradition
For line box, there is simple structure, connection is reliable, sealing effectiveness is preferable.
