Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly terminal box, belongs to the photovoltaic solar technical field.
Background technology
The solar photovoltaic assembly terminal box is the Overbridge device that the lead-in wire with solar photovoltaic assembly is connected with external lead wire, and diode is equipped with in inside.
Existing solar photovoltaic assembly terminal box adopts the integral type casting mostly, is to adopt the structure processing of lid and box body even the minority model is arranged, but also adopts the encapsulating integral sealing after being shaped, can't realize separating, in case break down, must wholely excise old terminal box, cause great waste.The general band binding post that confluxes that adopts of terminal box connects diode, this binding post is carrier with the terminal box, integrated level own is not high, and diode can produce certain fatigue strength with being connected of this binding post in the long-term use, is unfavorable for the switching performance of diode.
When solar photovoltaic assembly generates electricity, bigger electric current can flow through the diode in the solar photovoltaic assembly terminal box, make the diode heating, as if untimely heat is left, under the continuous high temperature state, the diode behavior that works long hours can descend gradually, the lost of life, also can cause the circuit open circuit when serious, finally influence the work of solar photovoltaic assembly, even damage expensive solar photovoltaic assembly.The general solar photovoltaic assembly terminal box of using does not have reliable heat abstractor, and heat dispersion is relatively poor, the long-term use life-span that can influence diode.
The utility model content
The purpose of this utility model is: the problem at above-mentioned prior art exists, the good solar photovoltaic assembly terminal box of a kind of heat dispersion is proposed, and be beneficial to production, be convenient to maintenance.
In order to reach above purpose, solar photovoltaic assembly terminal box of the present utility model comprises box body and the lid that matches with it, described box body outside is connected with cable and cable connector, its improvements are, described terminal box also comprises the circuit board that is placed in the box body, described circuit board is the printed circuit board of one group of diode of welding, and the outside of described each diode is fixed with radiator respectively.
The utility model further improves, and described printed circuit board is provided with the band location hole that confluxes, and is used for welding the band that confluxes.
The utility model further improves.Described lid is provided with trip, and box body is engaged with snap fit with lid.
Diode of the present utility model is welded on the printed circuit board, dispels the heat in the space that can make full use of in the terminal box, and each diode is furnished with radiator respectively, more helps reducing the temperature of diode heating in the course of work, prolongs diode useful life.
The utility model does not use the band binding post that confluxes, and the band that will conflux directly is welded on the printed circuit board, has not only improved the product integrated level, can also avoid using the problem of confluxing and being with binding post to bring.
Box body of the present utility model adopts snap fit to combine with lid, not only can guarantee sealing, also is convenient to dismounting, helps maintenance; In addition, the box body front end cut zone that the import department of band has added the band that confluxes of confluxing, the every band that confluxes all has an own distinct area, has guaranteed conflux in transportation, assembling process independence between the band of assembly.
After adopting structure of the present utility model, the heat dispersion of terminal box is good, long service life, and cost is lower, is beneficial to production, is convenient to maintenance.
