Vertical connection structure of photovoltaic module and photovoltaic module thereof

Abstract

The invention discloses a vertical connection structure of a photovoltaic module and a photovoltaic module thereof. The vertical connection structure comprises a corner, which is provided with connecting arms, sawtooth surfaces and stop surfaces; the two connecting arms are vertically connected in an L shape, and each connecting arm is divided into an insertion section and a connection section along the length direction; the sawtooth surfaces are located on the insertion sections; the stop surfaces are located at the boundaries of the insertion sections and the connection sections, and are perpendicular to the length directions of the insertion sections and the connection sections; the insertion sections are in contact connection with the inner cavity of a profile, and the stop surfaces are in contact with the ends of the profile; and the corner guard is provided with a groove having an L-shaped length, the groove is in contact with the inner sides of the connection sections, and whenthe corner guard is assembled with the corner, the cross-sectional contours of the corner guard at the groove and the corner are the same as the cross-sectional contour of the profile. The corner clamps the periphery of the corner guard, the profile clamps the two ends of the corner guard, and the three are fixed tightly, so that the sharpness of the corner of the profile is eliminated, the repairof the profile is avoided and the assembly work of the personnel is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic module accessories, in particular to a vertical connection structure of a photovoltaic module and the photovoltaic module. Background technique [0002] Photovoltaic modules need to protect and connect their frames through profiles. At present, in the frame of traditional crystalline silicon solar modules, the adjacent aluminum materials are cut into 45° angles for butt joint. There may be burrs even after sanding. The grinding process also increases the waste of human resources, and there may still be burrs and protrusions after grinding, especially some aluminum materials with black anti-corrosion coating on the surface will reveal the silver-white internal structure after grinding, which is harmful to appearance and anti-corrosion. unfavorable. At the same time, conventional profiles are easy to accumulate dust near the edge banding area. After a long time, they will block the cells, resulting in ...
