Description
Technical field
The present invention relates to solar-photovoltaic technology field, particularly a kind of terminal box for two glass solar module.
Background technology
Increasingly serious along with Global climate change and problem of environmental pollution, green regenerative energy sources is more and more paid attention to and fast-developing.Solar energy is a kind of renewable resource, and the solar cell technology utilizing photovoltaic effect to carry out generating electricity enjoys common people to pay close attention to.Solar cell is by the material that can produce photovoltaic effect, as the materials such as silicon, GaAs, indium selenium copper are made, light energy conversion can be become electric energy.Traditional silicon chip solar battery assembly, due to light tight, be generally used in the top that more remote outdoor sports ground forms photovoltaic generating system or is placed in building, which limits the range of application of photovoltaic generation; Therefore, light transmission preferably two glass solar module is just developed, the photovoltaic module that the solar cell piece that two glass assembly adds centre by two sheet glass forms, it directly can build up photovoltaic-architecture-integral project (BIPV) as building material product, such as constructure screen wall, glass sunlight house, bicycle shed etc., the effective area of building and space can be reasonably utilized to generate electricity, even also can large-scale application in city.
In the actual use of photovoltaic module, need the electric energy using photovoltaic component terminal box to be produced by photovoltaic module to draw and be connected with outside load.Therefore, photovoltaic component terminal box is the critical component that photovoltaic module builds various electricity generation system, and except as the most basic electric energy leads component, terminal box is also required for protection photovoltaic module.Therefore, the quality of terminal box itself and electrical reliability have important impact for the safety of the even whole photovoltaic generating system of photovoltaic module, stable operation, therefore, when terminal box designs, need the electrical connection protection problem considering itself; In addition, consider that two glass assembly needs good light transmission, the terminal box of two glass assembly is generally all done more much smaller than common assembly junction box, and tray interior space is little, the high temperature of conductive copper sheet affects parts around than being easier to, and can affect the overcurrent capability of conductive copper plate in box body; In addition, the creepage distance of the terminal box of traditional slab construction is smaller, affects the fail safe that it uses.
Summary of the invention
For the problem in existing application, the present invention proposes a kind of terminal box being applicable to two glass solar module, and it can have safer creepage distance and higher overcurrent capability, and manufacturing process is simpler.
To achieve the object of the present invention, the two glass solar module terminal box of one of the present invention comprises base, the upper cover of the lid shape fastened with base, high-temperature resistance plastice base plate is provided with in described base, described base plate is arranged conductive copper plate electrode, diode is connected between adjacent conductive copper plate electrode, and the two ends of base are provided with cable buckling, and the cable picked out from terminal box is fixed by cable buckling and terminal box.
Preferably, cover on described and be provided with multiple apopore.
Preferred again, described base and base plate are split-type design.
Preferred again, described baseboard material is nylon.
Preferred again, adopt ultrasonic bonding to fix between described cable buckling and base.
The upper cover of of the present invention pair of glass solar module terminal box is lid shape, increases creepage distance, uses safer; Upper cover design has apopore that the water in terminal box can be allowed to flow out from hole; Base plate and base adopt split-type design, and base plate uses high-temperature resistance plastice, strengthens the overcurrent capability of the copper coin on it; Ultrasonic bonding is utilized to make technique more simple and reliable.

Embodiment
With reference to the overall structure exploded perspective view of a kind of pair of glass solar module terminal box and the schematic diagram of its building block structure shown in Fig. 2 to Fig. 5 of the one embodiment of the invention shown in Fig. 1, described terminal box comprises base 20, the upper cover 10 of the lid shape fastened with base 20, high-temperature resistance plastice base plate 22 is provided with in described base 20, described base plate 22 arranges conductive copper plate electrode 24, diode 26 is connected between adjacent conductive copper plate electrode, the two ends of base 22 are provided with cable buckling 28, the cable 30 picked out from terminal box is fixed by cable buckling 28 and terminal box.
The upper cover of the terminal box in the present embodiment is the lid shape of hollow instead of adopts tabular upper cover.In existing terminal box, as shown in Figure 6A, upper cover 10 ' is all the plate armature adopted substantially, and the bonding gap between upper cover 10 ' and base 20 ' is on the top of lid, and creepage distance is now d ' (conductive copper plate electrode 24 ' is to the distance of bonding gap); And in the present invention, upper cover 10 adopts the structure of lid shape, the bonding gap of upper cover 10 and base 20 is in the bottom of terminal box, creepage distance is now (d1+d2) (conductive copper plate electrode 24 is to distance of bonding gap), obviously, design of the present invention increases creepage distance, safer when terminal box is used.
One preferred embodiment in, described upper cover 10 is provided with multiple apopore 12, and so, the steam in terminal box can flow out from apopore 12, improve terminal box use fail safe.
In addition, base plate 22 and the base 20 of terminal box adopt split-type design, base plate 22 uses high-temperature resistance plastice as nylon, can allow larger temperature rise and the heating that is unlikely to conductive copper plate produces infringement to base and causes scrapping of terminal box, so strengthen the overcurrent capability of terminal box.
Ultrasonic bonding is adopted to fix between described cable buckling 28 and base 20.Ultrasonic bonding is the surface utilizing dither wave loops need weld to base and buckle, when pressurizeing, makes the mutual friction of two body surface phases and the fusion that formed between molecular layer.This welding procedure is simple and reliable, ensure that the intensity that cable is fixing.
Of the present invention pair of glass solar module terminal box adopts lid shape, increases creepage distance, uses safer; Upper cover design has apopore that the water entering terminal box can be allowed to flow out from hole; Base plate and base adopt split-type design, and base plate uses high-temperature resistance plastice, enhances the current capacity of terminal box; Utilize ultrasonic bonding attached cable, technique is more simple and reliable.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
