In the scheme of the utility model, the diode is arranged on the first base; the packaging body is made of radiating material and has high radiating performance and high waterproofing level; the radiating aluminum is connected with the rear end of the bus bar clamping spring and can transfer heat out of the second base, thereby enhancing the radiating performance of the bus bar clamping spring; and the leakage current of the diode can be reduced so that the component loss is reduced by 5 percent.
Description
Technical field
The utility model relates to a kind of terminal box, and particularly a kind of photovoltaic junction box that electric energy transmitting is come out and heat dispersion is good that can conveniently become solar energy converting belongs to the power transmitting device technical field.
Background technology
In the photovoltaic industry, needs commonly used are used terminal box, and this terminal box is used for the power delivery of transform light energy one-tenth to power circuit; Luminous energy mainly is to rely on sunlight, because the unsteadiness of luminous energy, it is strong certain part sunray to occur on the solar panels of photovoltaic generation, a little less than certain part sunlight, even do not have, it is strong to produce certain part electric energy like this, and certain part electric energy is weak even do not have, for electric energy transmitting is come out, just need a kind of special terminal box; Generally, all circuit elements all are arranged in the base of terminal box in the terminal box, because base needs sealing, cause its heat dispersion not good.
The utility model content
The utility model purpose is to have proposed a kind of photovoltaic junction box that electric energy transmitting is come out and heat dispersion is good that can conveniently become solar energy converting in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of photovoltaic junction box comprises first base, busbar jump ring, first cable, second cable, loam cake, second base, diode, heat radiation aluminium flake, packaging body; Described first cable, second cable are arranged on first base; Described busbar jump ring has many groups, is arranged on side by side on first base, is communicated with by lead between described busbar jump ring; Described diode is arranged on first base; Described diode and described busbar jump ring are arranged in parallel; Described loam cake covers the front end of busbar jump ring; Described heat radiation aluminium flake is connected with the rear end of busbar jump ring; Described second base and first base wrap the installation end of rear end, diode, mounting panel, first joint and second joint of busbar jump ring; Described second base is provided with opening; Described packaging body injects parcel by the parts of first base and second base parcel from opening.
Preferably, described packaging body adopts silica gel material to make.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Photovoltaic module terminal box of the present utility model, described binding post connect the power supply that solar energy converting becomes, if a certain group of power supply do not have electricity, then can pass through diode arranged side by side, and the power supply that adjacent binding post is communicated with is communicated with, convenient output electric energy; Diode is arranged on first base simultaneously; Described packaging body adopts heat sink material to make, and heat dispersion is good, the classification of waterproof height; Described heat radiation aluminium flake links to each other with busbar jump ring rear end, with the outside of thermal energy conduction to second base, increases the heat dispersion of busbar jump ring; The Leakage Current that reduces diode makes Module Dissipation reduce by 5%.
