Background technology
At present, in the electric connection technology of solar power system, usual employing solar photovoltaic cell junction box realizes the electrical connection between photovoltaic module and inverter, metallic conductor and diode is also had in conventional photovoltaic cell junction box installation cavity, wherein several diodes in bulk are welded on several sheet metals by complicated procedures of forming, very easily produce hidden danger and the waste such as failure welding, diode pin breakage in process of production.
The electric property that diode in installation cavity and metallic conductor are covered to prevent the impurity such as rainwater from entering into by the form of filling with fluid sealant in terminal box installation cavity inside cavity affects photovoltaic cell junction box by conventional photovoltaic battery connecting box completely, but the amount of uncontrollable encapsulating in actual encapsulating process, thus the lex primaria of encapsulating and cannot being guaranteed to the consistency of the cladding thickness of " movement ".
During photovoltaic cell junction box work, diode can produce a large amount of heats, and conventional photovoltaic battery wire box plate directly contacts with photovoltaic component back plate, heat photovoltaic cell junction box base plate can be made to produce distortion by the mode of heat trnasfer and photovoltaic component back plate burns by temperatures involved and lost efficacy.
Summary of the invention
Technical problem to be solved by this invention is that to provide a kind of for above-mentioned prior art take diode integration module as the full encapsulating photovoltaic special junction box of " movement ", can effectively control encapsulating amount, guarantee the lex primaria of encapsulating and the consistency of movement cladding thickness, can prevent the heat produced because of internal body diodes from causing distortion to base plate or burning simultaneously, improve the useful life of photovoltaic module.
The present invention's adopted technical scheme that solves the problem is: a kind of take diode integration module as the full encapsulating photovoltaic special junction box of " movement ", it comprises the upper cover and housing that can mutually cover together, and diode integration module, in the surrounding of described housing is provided with, the interior enclosure wall of outer layout and outer enclosure wall, described interior enclosure wall is as the calibrated altitude of encapsulating, and its height is lower than the height of outer enclosure wall, the housing bottom being positioned at enclosure wall inside is provided with high-temperature resistance plastice part, mutual clamping between described high-temperature resistance plastice part and housing, the housing of described diode integration module is fixed on high-temperature resistance plastice part, the back side of described high-temperature resistance plastice part is offered groove and is formed hanging structure, cable on described diode integration module is installed on pin and is provided with cable core, cathode plug and anode plug is connected in the end of described cable core.
Preferably, described high-temperature resistance plastice part is provided with multiple hasp for fixing diode integration module, the housing of described diode integration module is fixed on high-temperature resistance plastice part by hasp.
Preferably, on the downside of described housing, enclosure wall and outer enclosure wall offer the draw-in groove be interconnected, described cable core is passed outside housing through draw-in groove by enclosure interior, and coordinates fixing with draw-in groove by wire pressing block.
Compared with prior art, the invention has the advantages that:
1) adopt diode integration module to replace original diode and sheet metal welded structure body as photovoltaic junction box " movement ", " movement " is directly installed in several prefabricated hasps of terminal box box chamber, makes it be fixed in junction box body.The cable " movement " carried is installed pin and is effectively connected with cable core.Installing cables fixes wire pressing block again.Photovoltaic special junction box has been assembled, and terminal box assembling is simple to operate, reliable.
2) in order to after ensureing that this terminal box is installed on photovoltaic component back plate, inject casting glue lex primaria and to " movement " cladding thickness consistency, the inside and outside twice enclosure wall of set of terminal box, outer enclosure wall plays firm and external form effect as box body outer wall, interior enclosure wall is lower than outer enclosure wall, play and control the effect that encapsulating amount and unnecessary glue overflow cofferdam, guarantee the accuracy of encapsulating amount, effectively prevent the very few or too much lid that affects of encapsulating amount from installing.
3) in order to avoid in terminal box use procedure, because of the heating of diode integration module, bottom deformation and photovoltaic component back plate is made to burn by temperatures involved and lose efficacy through terminal box base plate heat trnasfer.Terminal box base plate of the present invention, be made up of the high-temperature resistance plastice part embedded, and be unsettled design bottom this base plate, high temperature resistant base plate is installed with diode integration module, the high temperature of diode integration module can be born indeformable and high temperature is not directly conducted to photovoltaic component back plate.
