Novel intelligent junction box

The invention discloses a novel intelligent junction box which comprises a box body (1) and a box cover (2) and is characterized in that a printed circuit board (PCB) (3) with an intelligent chip is arranged in the box cover (2), an input/output lead (31) of the PCB can be connected with a card interface (4) on the box body, the card interface (4) is connected to a bus bar (5), the box body (1) and the box cover (2) are detachably connected, and a sealing structure (6) is arranged between the box body (1) and the box cover (2) and can be used for internal water sealing of the junction box. By the novel intelligent junction box, the technical problems of slow cooling of the intelligent junction box, high working temperature inside the chip and difficulty in replacing the PCB after damage in the prior art are solved. The novel intelligent junction box has the advantages of favorable cooling performance and high reliability and is easy to maintain and replace.
