Abstract
The utility model relates to a split type junction box assembly comprising a plurality of cell strings arranged inside the assembly. The split type junction box assembly is characterized in that the cell strings, at the left, among the plurality of cell strings (1) are connected by a bus bar (21); ones, in the middle, of the plurality of cell strings (1) are connected by one or a plurality of bus bars II (22); and ones, at the right, of plurality of cell strings (1) are connected by a bus bar III (23). Besides, a junction box I (31), one or more junction boxes II (32) and a conjunction box III (33) are respectively installed at the left, middle and right of the top of the back of the assembly. According to the utility model, materials for insulated bars and EVAs are saved and the cable length during the using is also saved. The overlapping portions of the bus bars are reduced; and thus the assembly resistance and the output resistance are reduced. Therefore, the provided split type junction box assembly has the following advantages: not only is the cost saved but also the finished assembly power is not reduced.
Description
Technical field
The utility model relates to a kind of split junction box assembly.
Background technology
Solar power generation is to utilize semi-conductive interface that photovoltaic effect takes place, and luminous energy is directly changed into a kind of technology of electric energy.Solar components is by solar cell string series connection back encapsulation, cooperates various parts to assemble again, so the generating efficiency of solar components not merely is the influence of solar cell string, the influence of miscellaneous part is also very important.
Referring to Fig. 1 and Fig. 2, traditional solar components, be 1 series connection of a plurality of battery strings after, coupled together by busbar 2, encapsulate again, lamination frames up, and a terminal box 3 is installed.Such mounting means, terminal box 3 will be installed in centre position, top, the assembly back side, guarantee that busbar 2 and terminal box join, and busbar 2 just has lap, causes waste of material and increases assembly resistance.In order to guarantee not short circuit between two battery strings, a bigger insulation strip and EVA4 be arranged.Waste material increases cost.When solar components is installed, serial or parallel connection together, in order to guarantee normal linking to each other, the cable of terminal box is wanted long enough, and cable resistance is increased, and not only causes waste of material but also increases the assembly output resistance, thereby the finished product component power is descended.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of not only saving cost is provided, and the finished product component power split junction box assembly that can not descend.
The purpose of this utility model is achieved in that
A kind of split junction box assembly, it comprises a plurality of battery strings of component internal, a plurality of battery strings of left part connect by a busbar I, a plurality of battery strings at middle part connect by a busbar II, a plurality of battery strings of right part also connect by one or more busbar III, left part, middle part and the right part on top, the assembly back side installed terminal box I, one or more terminal box II and terminal box III respectively, and the component internal of described terminal box I, one or more terminal box II and terminal box III corresponding position respectively arranges an insulation strip and EVA.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has been saved the material of insulation strip and EVA and the length of cable when using, reduce the lap of busbar, reduce assembly resistance and output resistance, make this split junction box assembly have and not only save cost, and the finished product component power advantage that can not descend.
Description of drawings
Fig. 1 is the internal structure schematic diagram of traditional wired case assembly.
Fig. 2 is the structure schematic diagram of traditional wired case assembly.
Fig. 3 is the internal structure schematic diagram of the utility model split junction box assembly.
Fig. 4 is the structure schematic diagram of the utility model split junction box assembly.
Wherein:
Battery strings 1
Busbar 2, busbar I21, busbar II22, busbar III23
Terminal box 3, terminal box I31, terminal box II32, terminal box III33
Insulation strip and EVA4.
Embodiment
Referring to Fig. 3 and Fig. 4, a kind of split junction box assembly that the utility model relates to, it comprises inner a plurality of battery strings 1, a plurality of battery strings 1 of left part connect by a busbar I21, a plurality of battery strings 1 at middle part connect by one or more busbar II22, a plurality of battery strings 1 of right part also connect by a busbar III23, in order to guarantee left part, 1 not short circuit of two battery strings of middle part and right part, left part on top, the assembly back side, middle part and right part are installed terminal box I31 respectively, one or more terminal box II32 and terminal box III33, the left part of each terminal box corresponding position, middle part and right part all arrange an insulation strip and EVA4, traditional relatively insulation strip and EVA, the material that this utility model is used is less.
During use, be connected by cable between the terminal box I31 of adjacent two split junction box assemblies and the terminal box III33 and get final product, reduced the length of cable.
Claims (1)
