Patent No.: 200910305097.6 201020203781.1


I. The integrated connector of the junction box has been adopted their own materials to double back and form the two circular grooves which could close contact with the cylindrical diode pin. That's another important invention and breakthrough in PV junction box field.
II. Better meeting the diode's pins, closer integration, more extensive contact surface, these minimize the contact resistance, and the product voltage drop and degree of output power lossing could be lower.
III. With full-fit mechanical retaining mechanism, its service life is much longer than the one with point-like linear connection and welded connection.
IV. The integrated connector system as a unity, is a stereo conductive transmission system with the diodes' pins plug into the holes to be together as one piece, so the performance of the transmitted power is greater.
V. The integrated junction box connectors mold as the one, instead of three or more, which has saved more non-ferrous metals
