Description

Solar photovoltaic assembly rosette
Technical field
This utility model belongs to solar photovoltaic battery component technical field, is specifically related to a kind of solar photovoltaic assembly rosette.
Background technology
Solar photovoltaic assembly rosette is the vitals of output sun-generated electric power, is the transition apparatus enforcement of solar cell lead and external lead wire being connected, generally by box body, lid, the bypass diode being arranged in cassette holder be conductively connected mechanism and constitute.The effect of aforesaid bypass diode is to avoid reverse charging undermine solar-energy photo-voltaic cell and prevent from affecting the normal work of whole solar photovoltaic battery component system because of a solar-energy photo-voltaic cell short circuit.
nullThe technical information about solar photovoltaic assembly rosette it is no lack of in disclosed Chinese patent literature,As: CN201639227U(solar photovoltaic assembly terminal block housings)、CN101944546B(solar photovoltaic assembly rosette)、CN101442280A(solar photovoltaic assembly rosette)、The structure-improved of CN2716748Y(solar assembly junction box)、The rosette of the output lead of CN101138098A(solar energy module and the installation method of this rosette)、CN200941388Y(Wiring box for solar photovoltaic electrification component)、CN201075856Y(solar energy photovoltaic metallic wiring box)、CN101286626A(solar photovoltaic metallic wiring box) and CN101459392A(solar-energy photo-voltaic cell system rosette),Etc..
