The photovoltaic junction box for roof construction comprises a box body, the box body is internally provided with a protection module, the protection module is connected with assembly cables and assembly buses, the other ends of the 8 assembly cables and the 2 assembly buses extend out of the box body, and the surface of the box body is provided with a buckle rail matched with the buckle. The photovoltaic junction box for roof construction has the advantages of high connection efficiency and convenient installation and maintenance.
Description
Technical field
The present invention relates to photovoltaic module technical field, especially relate to a kind of roof building photovoltaic junction box.
Background technology
Photovoltaic junction box is a vitals of solar photovoltaic assembly; can simultaneously for the connection of the bypass diode module of the polysilicon photovoltaic PV panel of multiple assembly, its energy protecting illumination assembly to produce when there is hot spot effect can not the battery component of crested consume.Usually, 1 photovoltaic junction box is directly fixed on 1 piece of photovoltaic module, thus efficiency is lower, and installs and maintenance all comparatively inconvenience.
Summary of the invention
The object of this invention is to provide a kind of roof building photovoltaic junction box, it is high that it has joint efficiency, and install and keep in repair conveniently feature.
The technical solution adopted in the present invention is: roof building photovoltaic junction box; it is fixed on the main joist of building; this main joist is provided with buckle; this roof building photovoltaic junction box comprises box body, is provided with protection module in this box body, and this protection module is connected with assembly cable and component bus; the other end of this assembly cable and component bus all stretches out this box body; described assembly cable is 8, component bus is 2, meanwhile, and the buckle track that the surface of this box body is provided with and this buckle matches.
Described 8 assembly cables and 2 component buses are distributed in the left and right sides of this box body uniformly, simultaneously, the pass of the assembly cable and component bus that are positioned at the same side of this box body is: this component bus is positioned at centre, and the both sides of this component bus have 2 assembly cables respectively.
The present invention is advantageously: joint efficiency is high, and install and maintenance more for convenience.Roof building photovoltaic junction box of the present invention can be connected 4 pieces of photovoltaic modulies simultaneously, and is fixed on the main joist on roof by box body by buckle, thus install and maintenance all comparatively simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
In figure: 10, box body; 20, assembly cable; 30, component bus; 40, buckle track; 50, protection module; 60, buckle, 70, main joist.
Embodiment
Embodiment, as shown in Figure 1: roof building photovoltaic junction box, it is fixed on the main joist 70 of building, and this main joist 70 is provided with buckle 60.Concretely, this roof building photovoltaic junction box comprises box body 10, is provided with protection module 50 in this box body 10, and this protection module 50 is connected with assembly cable 20 and component bus 30.Concrete, the avris of this box body 10 is provided with 8 assembly cables 20 and 2 component buses 30, and the other end of this assembly cable 20 and component bus 30 all stretches out this box body 10.Like this, every 2 assembly cables 20 can connect 1 photovoltaic module, thus this terminal box can connect 4 pieces of photovoltaic modulies simultaneously, has higher joint efficiency.Meanwhile, the buckle track 40 that the surface of this box body 10 is provided with and this buckle 60 matches.That is, this buckle 60 is buckled in this buckle track 40.Like this, this terminal box passes through the cooperation of this buckle 60 and buckle track 40, this box body 10 can be fixed on easily on this main joist 70 or from this main joist 70 and take off, more for convenience.
Optimize, these 8 assembly cables 20 and 2 component buses 30 are distributed in the left and right sides of this box body 10 uniformly.That is, the both sides of this box body 10 have 4 assembly cables 20 and 1 component bus 30 respectively.Meanwhile, the pass of the assembly cable 20 and component bus 30 that are positioned at the same side of this box body 10 is: this component bus 30 is positioned at centre, and the both sides of this component bus 30 have 2 assembly cables 20 respectively.Like this, the distribution comparatively science of this assembly cable 20 and this component bus 30, is convenient to the distribution that photovoltaic module that this terminal box connects is comparatively neat.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
