Operation, some randomness of component shape after assembling.Another kind need to use dedicated corner brace riveting equipment using corner brace riveting assembling,
Processing efficiency is relatively low, and for reprocessing component, it is extremely difficult to remove frame ontology.In addition it is also connected using corner brace,
Such as:
CN102522440A discloses a kind of photovoltaic module corner brace clamping package assembly, and this corner brace clamping package assembly exists
When assembling with photovoltaic frame, by being arranged in the hole snapped on frame in corner brace, make to be located at corner brace adjacent both ends
Module frame fixed with corner brace.Above-mentioned corner brace clamping package assembly draws forming material using Aluminum extrusion, and connect with corner brace
Module frame it is consistent with the material of corner brace, therefore, module frame it is at high cost, do not have insulating properties, when installation, needs to consider
Ground connection, and the abilities such as the salt fog resistance of aluminium, aging, ultraviolet light are poor, cause the service life of module frame short, in addition, above-mentioned corner brace
Intensity it is low, structure is complicated, and installation and removal process is complicated.
Summary of the invention
This practical new purpose be to provide one kind avoid waste binder and increase photovoltaic laminate and composite material slot and
The composite material photovoltaic component frame of the effective contact area of binder.
Composite material photovoltaic component frame, including frame ontology, frame ontology are made of connecting component and support member, branch
Support part part is made of the first extension and the second extension, and one end intersection of one end of the first extension and the second extension makes to prop up
The section l-shaped of support part part, the other end and the connecting component of the first extension are fixed, and the other end of the second extension is freely
End, forms slot between support member and connecting component, the free end of the second extension or in face of the first of connecting component
Side wall surface is equipped with prevents the binder in slot from spilling into the protrusion outside slot when installing photovoltaic laminate.
Using above scheme, after the end of photovoltaic laminate is inserted into slot, the end of photovoltaic laminate is pressed from both sides
It holds between protrusion and second side wall surface of connecting component, since protrusion is to protrude from the first side wall face of support member, this
Sample, due to the presence in the gap, is avoided and is injected into so that forming gap between the end of photovoltaic laminate and the first side wall face
Suitable binder in slot overflows, and due to the presence of protrusion, blocking is formd to the excessive of binder, to increase
Photovoltaic laminate and composite material slot and the effective contact area of binder further increase photovoltaic laminate and frame installation
Reliability.
