Solar cell junction box

The invention discloses a solar cell junction box, which comprises a bus bar clamp spring, a diode clamp spring and at least two conducting brackets, wherein the cross sections of the conducting brackets are inversed-U-shaped; two side faces of a front part are provided with two symmetric holes; the middle parts of the conducting brackets are provided with accommodating cavities; the bus bar clamp spring is formed by bending an elastic sheet; at least a gap part is formed at the junction of the top surface and the side face of the back part of each conducting bracket; the diode clamp spring is formed by bending an elastic sheet and comprises an end face and a side face; the side face is provided with a convex part and a concave part; the diode clamp spring is clamped into the back part ofeach conducting bracket; the concave part is superposed with a part of the gap part of each conducting bracket; adjacent conducting brackets are connected with each other through a diode; a diode pinis inserted into the gap part of each conducting bracket; and the concave part of the diode clamp spring is tightly pressed against the diode pin, so that the diode pin is tightly jointed to each conducting bracket. The solar cell junction box has a simple structure, high compatibility and high maintainability, and is convenient to operate.
