Junction box and set of junction boxes and solar cell arrangement

摘要

Junction box (1, 21) of a solar cell arrangement, wherein the junction box comprises a lower part (3) and a separate, mechanically connected to the lower part upper part (7) and in one (3) of lower part and upper part first contact elements (C1 to C5), of which one part in the assembled state are connected to the solar cells and two of which (C1; C5) are connected to a connecting cable (5a; 5b) of the solar cell arrangement, and in the other (7) of the lower part and upper part interconnected second contact elements (S1 to S5 ), which contact the first contact elements electrically in the mounted state and connect to each other, and at least one electronic functional element (25; 27; 29) are arranged for realizing at least one additional function for at least a portion of the solar cells such that the functional element in the mounted state in the Solar cell array is inserted at least functionally, wherein at least one of the outgoing of the solar cell array Ans drain cable (5a; 5b) is electrically connected to the solar cell arrangement only in the mutually mechanically connected state of lower part (3) and upper part (7).
