In actual use, need the electric energy using photovoltaic component terminal box to be produced by photovoltaic module to draw to be connected with outside load.Therefore, photovoltaic component terminal box is the critical component that photovoltaic module builds various electricity generation system.In terminal box, generally will use diode, first can play bypass effect, and protection solar components normal power generation, can not affect whole electricity generation system because a certain piece of cell panel damages; Second can play the effect making electric current following current, can not puncture cell panel because of the adverse current of storage battery.
Separately, compared to traditional crystal-silicon solar cell photovoltaic module, membrane photovoltaic component occupy more beautiful outward appearance, has wider applicable situation, such as, can as the photovoltaic curtain wall of heavy construction, both attractive in appearancely also can make full use of wall area to generate electricity.This membrane photovoltaic component Area comparison is large, if use the terminal box that design comparison is as shown in Figure 1 traditional, the Area comparison of terminal box needs to connect with longer cable greatly and between terminal box on the one hand, is used in cost that is not too attractive in appearance on transparent or semitransparent membrane photovoltaic component and cable also higher.Another, because the diode in terminal box is heater members, also should consider the heat dissipation problem of terminal box, extend its useful life.Because Vehicles Collected from Market competition is fierce all the more, except the quality of product, the price of product is also important competitive method, therefore, needs to propose the little more attractive in appearance and lower-cost terminal box of a kind of volume being applicable to membrane photovoltaic component.
Summary of the invention
The object of the invention is, for the consideration improving product competitiveness, provide the little cost of a kind of volume lower and the composite type photovoltaic component terminal box of excellent radiation performance.
To achieve the object of the present invention, concrete, a kind of composite type photovoltaic component terminal box of the present invention comprises negative terminal box, halfway junction box and positive terminal box, described halfway junction box is located between negative terminal box and positive terminal box, and described halfway junction box is electrically connected by the busbar of photovoltaic module with described negative terminal box and positive terminal box; Two binding posts are provided with in the box body of each terminal box, one chip diode to be located between two binding posts and to be connected with binding post, in the plane of the binding post that wherein said chip diode is disposed therein, and the area of plane being provided with the binding post of diode does not arrange greatly the area of plane of the binding post of diode thereon; Described positive terminal box and negative terminal box also has cable link.
Preferably, the binding post in each terminal box body of described composite type photovoltaic component terminal box is provided with busbar solder pad, is provided with the hatch frame for busbar location in the front end of described pad.
Composite type photovoltaic component terminal box of the present invention, volume is little, and the stube cable of use is also less, improves aesthetics when it uses; Inner binding post adopt the better chip diode of heat dispersion and the area of plane of the binding post which is provided with diode is arranged larger, both having ensure that good radiating effect also can ensure the uniformity that tray interior dispels the heat; Separately on binding post, pre-set pad and busbar location hole, make the installation of terminal box more convenient.
