Technical field
The utility model relates to a kind of photovoltaic module with diode and terminal box thereof.
Background technology
Along with the continuous consumption and the pollution of traditional energy, the new forms of energy advantage embodies gradually, and its development is also more and more faster.Application of Solar Energy is more and more general; And diode is absolutely necessary therein; Solar components must be equipped with diode at output; Its effect is the unidirectional on state characteristic that utilizes diode, prevents that photovoltaic cell that reverse charging damages photovoltaic cell and prevents a unit from opening circuit to cause whole photovoltaic battery pack all can't use.
Adopt traditional plug-in type diode in the solar components, the package pins of diode adopts the copper tin plated materials of diameter 0.5mm-1mm, and the mode that in solar components, adopts welding or terminal to compress is fixed.When photovoltaic cell breaks down; Diode current flow work, have electric current and flow through diode this moment, because the diode package pin is thinner; The resistance band place of confluxing relatively is bigger; The diode pin place will consume a large amount of electric energy, produces more heat transfer simultaneously, has so just reduced the power output of black box.Simultaneously; Diode is to keep in repair one of more element in the solar components; Owing to long-term work under the condition of heating or reason such as thunderbolt, diode very easily damages, because the damage of diode accounts for more than sixty percent of photovoltaic module total failare rate; Must change the diode of damage for the operate as normal that guarantees whole system; Because diode adopts traditional welding or terminal mounting means, cause inconvenience at photovoltaic generation field replacement diode, influenced the application of diode in solar cell.Conventional diode because service time permanent positive and negative electrode indicate fuzzyly, very easily cause pin positive and negative electrode reversal connection phenomenon.
The utility model content
The utility model technical problem to be solved provides a kind of mistake installation, good heat dissipation effect, photovoltaic module easy for installation of preventing with diode and terminal box thereof.
The technical scheme of the utility model is:
The dispel the heat photovoltaic module diode of anti-error installation of a kind of plug-in; Comprise body, pin; Pin is arranged on an end of body, and the end surface shape that body is provided with pin is a rectangle, and pin is the sheet inserted sheet; Comprise anodal inserted sheet and negative pole inserted sheet, anodal inserted sheet and negative pole inserted sheet are T font layout at the end face of body.
Anodal inserted sheet is parallel with the long limit of body rectangle end face, and the negative pole inserted sheet is parallel with the minor face of body rectangle end face.
The material of pin is that copper is zinc-plated or copper is silver-plated.
The dispel the heat matching used terminal box of photovoltaic module diode of anti-error installation of a kind of plug-in is provided with and the suitable draw-in groove of diode sheet inserted sheet pin, is provided with jump ring in the draw-in groove.
Beneficial effect: the utility model is with the below of diode pin as for body; Pin has adopted the sheet inserted sheet; And being the T font arranges; Can be under specific condition with the feel diode of pegging graft easily, stopped conventional diode because service time permanent both positive and negative polarity indicate fuzzyly, cause pin both positive and negative polarity mistake that phenomenon is installed.
Pin sheet inserted sheet structure has increased the volume of pin, has reduced resistance value, has increased the providing capability of electric current, has reduced the consumption of electric energy, has improved the power output of assembly; Pin sheet inserted sheet structure has also increased area of dissipation, has quickened the heat radiation of diode in use, prolongs its useful life.Improve the reliability of photovoltaic module, reduce failure rate, reach energy maximum using, prolonged the useful life of overall optical photovoltaic assembly.
The card shape slot structure is set in the terminal box equally, only needs during installation the diode pin chucking is got final product, easy for installation, and be convenient to later period maintenance, and after diode damages, only need extract bad diode, plug new diode and get final product, do not need other aid.Change the mounting means that the welding of conventional diode is connected with terminal, not only increased the diode contact area, also strengthened the mechanical strength of diode, improved the anti-vibration ability in the photovoltaic module transportation.
