Corner connector, photovoltaic module and photovoltaic system

Abstract

The utility model provides a corner connector, a photovoltaic assembly and a photovoltaic system, and relates to the field of photovoltaic technology. The corner connector comprises two mounting parts of which the end parts are connected together; each mounting part comprises an upper plate, a limiting convex plate, a side plate and a lower plate which are connected in sequence; the upper plate and the limiting protruding plate are both located at the first end of the side plate. In the first direction, one end of the limiting protruding plate is fixed to the first end of the side plate, and the other end is fixed to the upper plate. The lower plate is fixed to the second end of the side plate, the first end and the second end of the side plate are opposite in the second direction, and the limiting protruding plate protrudes towards the lower plate; a notch is formed in the limiting protruding plate of each installation part, and each installation part further comprises a square fixing plate filled in the corresponding notch. The limiting protruding plate and the square fixing plate are both connected with the bent plate of the frame in a clamped mode, the square fixing plate is square in shape and clear in corner angle, the bent plate is strongly limited, the corner connector can be prevented from sliding out of a cavity of the frame, and assembling is easy.
