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, but diode is a heater members, in order to ensure the useful life of terminal box, must resolve the heat dissipation problem of junction box; In addition, along with the fierceness all the more of market competition, product not only will focus on quality and the Cost Problems of terminal box self, also need to consider Cost Problems when it uses, Ji Yaoshi assembly factory is more convenient when installing terminal box, save the time of technological operation, so improve the production efficiency of assembly factory.
Summary of the invention
The object of the invention is, for the consideration improving product competitiveness, provide a kind of being convenient to install and the photovoltaic component terminal box of excellent radiation performance.
To achieve the object of the present invention, concrete, of the present invention a kind of be convenient to install and the photovoltaic component terminal box of excellent radiation performance comprises box body and cable link, multiple binding post be connected with the solar battery convergent current bar of photovoltaic module is provided with in described box body, electrical connection is formed by chip diode between described binding post, and described chip diode is arranged on the surface of a binding post, be connected with adjacent binding post by pin, wherein, 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, and described multiple binding posts are provided with busbar solder pad, be provided with the hatch frame for busbar location in the front end of described pad.
Preferably, described binding post is four, and the area of plane of two binding posts is wherein greater than the area of plane of the binding post of both sides.
Preferred again, two binding post one of described centre is L-type, and one is Z-type, and these two binding posts are in being crisscross arranged.
Preferred again, described in be arranged on middle in the arragement direction of the diode between the binding post be crisscross arranged and the arragement direction of other diodes vertical.
Photovoltaic component terminal box of the present invention adopts the good chip diode of thermal diffusivity as bypass diode and is arranged on the surface of connecting terminal of junction box, and make the area of plane of the binding post which is provided with diode not be provided with greatly the area of plane of the binding post of diode thereon thus make the rapid heat dissipation of terminal box and dispel the heat evenly, by presetting pad and busbar location hole on binding post, the installation of terminal box and assembly can be made more convenient, Simplified flowsheet.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
What Figure 1 shows that one embodiment of the invention is convenient to installation and the photovoltaic component terminal box of excellent radiation performance;
Figure 2 shows that the structural representation of the part line terminal of the terminal box of Fig. 1.
Embodiment
By feature of the present invention and advantage, details are as follows by reference to the accompanying drawings.
One embodiment of the invention shown in Figure 1 be convenient to install and the photovoltaic component terminal box of excellent radiation performance, described terminal box comprises box body 10 and cable link 20, multiple binding post 102 be connected with the solar battery convergent current bar of photovoltaic module is provided with in described box body 10, 104, 106 and 108, electrical connection is formed by chip diode 14 between described binding post, and described chip diode 14 is arranged on the surface of a binding post, be connected with adjacent binding post by pin, wherein, 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, and described multiple binding posts are provided with busbar solder pad 1020, be provided with the hatch frame 1022 (as shown in Figure 2) for busbar location in the front end of described pad.
Then with reference to figure 1, in one preferably execution mode, the binding post of described photovoltaic component terminal box has 4, considers that the heat radiation in the middle part of terminal box is more difficult, arranges larger than the area of plane of the binding post of both sides by the area of plane of two binding posts of centre; More excellent, two binding post one mediated is designed to L-type, another is designed to Z-type, and these two binding posts are in being crisscross arranged, so these two binding post areas of plane both can have been made roughly the same, and the diode between these two binding posts can be arranged with the arragement direction being different from other diodes, the heat dissipation direction also by junction box binding post is adjusted to different directions, so, the heat radiation of junction box can be made more all efficiently even.
Of the present invention being convenient to shown in Figure 2 is installed and the project organization schematic diagram of the binding post of the tray interior of the photovoltaic component terminal box of excellent radiation performance, for the ease of the installation of terminal box on assembly, simplify mounting process, the binding post of terminal box of the present invention in box body pre-sets pad 1020 and busbar location hole 1022, when terminal box be installed to module backside carry out busbar and binding post be welded to connect time, busbar is crossed from assembly front and is directly inserted in hatch frame 1022 through rear, then directly can heat and busbar and pad are welded to connect, that so can conveniently weld carries out smoothly, operating personnel are without the need to the contraposition work carrying out busbar of effort.
Photovoltaic component terminal box of the present invention adopts the good chip diode of thermal diffusivity as bypass diode and the metal covering be arranged on by binding post on the surface of connecting terminal of junction box dispels the heat, and makes the area of plane of the binding post which is provided with diode not be provided with greatly the area of plane of the binding post of diode thereon thus make the not only rapid heat dissipation of terminal box and dispel the heat evenly; By presetting pad and busbar location hole on binding post, the installation of terminal box and assembly can be made more convenient, Simplified flowsheet, improving the production efficiency of assembly factory.
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.
