Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a corner bracket component for photovoltaic frames. Background Technology

[0002] When photovoltaic (PV) modules are installed outdoors, core components such as the PV glass and solar cells need to be fixed and protected by PV frames. PV frames are typically composed of four aluminum alloy profiles spliced ​​into a rectangular frame, with corner brackets used to connect adjacent profiles at right angles. Currently, most corner brackets for PV frames are single L-shaped metal pieces or ordinary plastic pieces. Metal corner brackets are heavy and prone to electrochemical corrosion with the aluminum alloy frame, while plastic corner brackets, due to their simple structure, are prone to deformation and breakage under the weight of the PV modules and outdoor wind pressure over long periods. Furthermore, ordinary plastic corner brackets are prone to aging and embrittlement under outdoor high temperatures and ultraviolet radiation, failing to meet the long-term lifespan requirements of PV modules. Additionally, the connection between the corner bracket and the frame lacks a dedicated sealing structure, allowing rainwater to easily seep into the frame through the installation holes, leading to oxidation and corrosion of the inner frame wall and affecting the lifespan of the PV modules. Therefore, we propose a new corner bracket assembly for PV frames. Utility Model Content
