A kind of double; two glass solar module rosette

Technical field

This utility model relates to solar-photovoltaic technology field, particularly to a kind of rosette for double; two glass solar modules。

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, utilizes the solar cell technology that photovoltaic effect carries out generating electricity to enjoy 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, it is possible to luminous energy is changed into electric energy。Traditional silicon chip solar battery assembly, due to light tight, be commonly used in the remote outdoor sports ground composition photovoltaic generating system of comparison or be placed in the top of building, which limits the range of application of photovoltaic generation；Therefore, light transmission double; two glass solar modules preferably are just developed, solar double-glass assemblies is added, by two sheet glass, the photovoltaic module that the solar cell piece of centre forms, it can build up photovoltaic-architecture-integral project (BIPV) directly as building material product, for example 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。

Photovoltaic module actually used in, it is necessary to use the load that the electric energy that produced by photovoltaic module of photovoltaic component terminal box is drawn with outside to be connected。Therefore, photovoltaic component terminal box is the critical component that photovoltaic module builds various electricity generation systems, except as most basic electric energy leads component, rosette is also required for protecting photovoltaic module。Therefore, the quality of rosette itself and electrical reliability have important impact for the safe and stable operation of the even whole photovoltaic generating system of photovoltaic module, therefore, when rosette designs, it is necessary to consider the electrical connection protection problem of itself；Additionally, considering that solar double-glass assemblies needs good light transmission, the rosette of solar double-glass assemblies is generally all made more much smaller than common assembly junction box, and tray interior space is little, the high temperature of conductive copper sheet is easier impact parts around, can affect the overcurrent capability of conductive copper plate in box body；It addition, the creep age distance of the rosette of traditional slab construction is smaller, affect the safety of its use。

Utility model content

For the problem in existing application, the utility model proposes a kind of rosette being applicable to double; two glass solar module, it can have safer creep age distance and higher overcurrent capability, and manufacturing process is simpler。

For reaching the purpose of this utility model, the double; two glass solar module rosette of one of the present utility model includes base, upper cover with the lid shape that base fastens, high-temperature resistance plastice base plate it is provided with in described base, described base plate arranges 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 rosette is fixed by cable buckling and rosette。

Preferably, cover on described and be provided with multiple apopore。

Further preferably, described base and base plate are split-type design。

Further preferably, described baseboard material is nylon。

Further preferably, ultrasonic bonding is adopted to fix between described cable buckling and base。

The beneficial effects of the utility model are, the upper cover of described double; two glass solar module rosettees is lid shape, increases creep age distance, uses safer；Upper cover design has apopore that the water in rosette can be allowed to flow out from hole；Base plate and base adopt split-type design, and base plate uses high-temperature resistance plastice, improves the overcurrent capability of copper coin thereon；Ultrasonic bonding is utilized to make technique simpler reliably。

Detailed description of the invention

The schematic diagram of its building block structure shown in the overall structure exploded perspective view of a kind of pair of glass solar module rosette of a reference embodiment of the present utility model shown in Fig. 1 and Fig. 2 to Fig. 5, described rosette includes base 20, upper cover 10 with the lid shape that base 20 fastens, it is provided with high-temperature resistance plastice base plate 22 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 rosette is fixed by cable buckling 28 and rosette。

The upper cover of the rosette in the present embodiment is the lid shape of hollow rather than adopts tabular upper cover。In existing rosette, as shown in Figure 6A, upper cover 10 ' is essentially all the plate armature of employing, and the bonding gap between upper cover 10 ' and base 20 ' is on the top of lid, and creep age distance now is d ' (conductive copper plate electrode 24 ' to the distance of bonding gap)；And in this utility model, upper cover 10 adopts the structure of lid shape, the bonding gap of upper cover 10 and base 20 is in the bottom of rosette, creep age distance now is (d1+d2) (conductive copper plate electrode 24 to the distance of bonding gap), obviously, design of the present utility model increases creep age distance, safer when making rosette use。

One preferred embodiment in, described upper cover 10 is provided with multiple apopore 12, and so, the steam in rosette can flow out from apopore 12, improve rosette use safety。

Additionally, base plate 22 and the base 20 of rosette adopt split-type design, base plate 22 uses high-temperature resistance plastice such as nylon, it is possible to allows relatively larger temperature rise to be unlikely to generating heat of conductive copper plate and base generation infringement is caused scrapping of rosette, so strengthens the overcurrent capability of rosette。

Ultrasonic bonding is adopted to fix between described cable buckling 28 and base 20。Ultrasonic bonding is the surface utilizing dither wave loops need to weld to base and buckle, when pressurization, and the fusion making two body surface phase mutual friction and being formed between molecular layer。This welding procedure is simple and reliable, it is ensured that the intensity that cable is fixing。

Of the present utility model pair of glass solar module rosette adopts lid shape, increases creep age distance, uses safer；Upper cover design has apopore that the water entering rosette 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 rosette；Utilizing ultrasonic bonding to fix cable, technique is simpler reliably。

This utility model is not limited to described embodiment, and those skilled in the art, namely disclosing in scope without departing from spirit of the present utility model, still can make some and revises or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion。
