Description

Be suitable for being mounted to the terminal box of photovoltaic module side

Technical field

The utility model belongs to sun-generated electric power component technology field, is specifically related to a kind of terminal box that is suitable for being mounted to photovoltaic module side

Background technology

The abbreviation (as follows) that above mentioned photovoltaic module is the photovoltaic modular assembly.Such as those of skill in the art the reason of knowledge, Wiring box for solar photovoltaic electrification component is the vitals of output sun-generated electric power, comprises the terminal box box body, is located at bypass diode, electric wire and cable connector in the box body.Terminal box is as the transition apparatus that solar cell lead is connected with external lead wire, in inside the effect of set aforesaid bypass diode be prevent reverse charging and undermine solar-energy photo-voltaic cell and prevent because of a solar-energy photo-voltaic cell short circuit causes whole solar photovoltaic battery component can't operate as normal.

can be no lack of in disclosed Chinese patent document around the technical scheme of solar photovoltaic assembly terminal box heat radiation and are seen in.The solar photovoltaic assembly terminal box that patent of invention publication number CN101442280A recommends has remedied the CN2716748Y in the prior art (structure-improved of solar assembly junction box), CN101138098A (terminal box of the output line of solar energy module and the installation method of this terminal box), CN200941388Y (solar components electrification component wiring box) and CN201075856Y existing logical frauds such as (solar energy photovoltaic metallic wiring boxes); Specifically can be referring to the 2nd page of the 2nd row of the 1st page of inverse 8-of specification of CN101442280A; This patent application scheme is that bypass diode is installed on one piece of fin; Both sides at the long side direction of box body constitute the box wing; Exterior bottom at the middle part of the long side direction of box body extends raised line at interval, is made up of and the extraneous air duct that communicates the space between the raised line.Has desirable result of ventilating heat dissipation when undoubtedly this patent application scheme is on being installed on solar photovoltaic cell panel.The solar photovoltaic metallic wiring box that CN101286626A discloses is between the shell of aluminium alloy and the nonmetal inner casing of ring-type, heat-dissipating cavity to be set, and uses and improves waterproof and dampproof and radiating effect.Through heat abstractor is set on the lid, heat abstractor is made up of some fin that tilt with respect to the lid upper surface with terminal box in the solar-energy photo-voltaic cell system that CN101459392A discloses, and the ventilating air permeability of butted line box has positive effect.

The photovoltaic module wiring that give an example above being not limited to all proposes around the radiating effect that improves terminal box, and all terminal box is considered and be installed on the photovoltaic module back side and design.Yet, when being installed on the photovoltaic module back side, terminal box need on the encapsulating material at the back side of solar photovoltaic cell panel or closed glass, punch, so that being caused terminal box, electrode wires connects.This mounting means not only bothers, and the degree on the photovoltaic battery panel that occupied is the area of terminal box size, and when solar photovoltaic assembly is installed on other carrier, tends to produce the problem that suffers the terminal box interference.

" junction box of solar module " that Chinese utility model patent Granted publication CN201742052U recommends can be eliminated aforesaid drawback, promptly can be installed to the side of photovoltaic module.But this patent scheme is because the structure of terminal box self remains shortcoming, therefore when mounted need be, otherwise can't be attached to the side of photovoltaic module by means of the sicker cementation, and specifically can be referring to the signal of specification Fig. 4 of this patent.Structure can be known thus, in the application of reality, can expose following technical problem: the one, and be that sicker is installed owing to need to rely on auxiliary material, therefore installation is loaded down with trivial details relatively, and installation cost is big; The 2nd, installation effectiveness is low, and erector's labour intensity is big; The 3rd, because the weatherability effect of sicker such as glue etc. is fragile, easy ageing, thereby be difficult to ensure that lasting common needs reach the firm effect of 20-25, in case loosening and even come off, then can seriously undermine the photovoltaic module; The 4th, in a single day owing to install, therefore suffer external impacts by means of sicker, just there is the anxiety that comes off.

In view of above-mentioned prior art, be necessary rationally to improve, for this reason, the applicant has done positive and useful exploration, and the technical scheme that will introduce below produces under this background
