Description

A kind of solar photovoltaic assembly terminal box
Technical field
The utility model relates to and a kind of solar energy converting is become the accessory of the equipment of electric energy, especially relates to a kind of solar photovoltaic assembly terminal box.
Background technology
In the prior art, bypass diode all is to be fixed on earlier on the metal terminal to be installed on the box body again, and being viscose glue, box body is fixed on the solar panel back, because bypass diode and binding post give out a large amount of heat, when being prone to problem comparatively speaking, take away lid, repair at outdoor on-the-spot solar panel back even the sled lower box body is changed, maintenance difficult and easily solar panel is caused damage.Therefore, the technical staff thirsts for this is improved.
The utility model content
For overcoming the deficiencies in the prior art, provide a kind of solar photovoltaic assembly terminal box of being convenient to bypass diode is installed, changed and can effectively protect solar panel.
For achieving the above object, the utility model is realized by following technical solution:
A kind of solar photovoltaic assembly terminal box comprises box body 1, box body assembly assembly 001, lid 10; Described box body 1 bottom is provided with 4 place's fixed grooves 12, and fixedly hole clipping 13 of 4 places is arranged in fixed groove 12; 4 elastic clips 2 pass corresponding fixedly hole clipping 13 and are fixed together with box body 1 and constitute box body assembly assembly 001 in fixed groove 12; Bypass diode 5 and connection fittings are fastened on the lid 10, and the box body barricade 19 of PPO material has been installed in the left and right sides of box body 1.
Compared with prior art: the beneficial effects of the utility model are: bypass diode 5 and connection fittings are fastened on the lid 10, are convenient to install, dismantle, keep in repair and change, effectively prolong the life-span of solar panel, and simple in structure, with low cost.
Description of drawings
For ease of understanding the utility model, the spy is further specified in conjunction with the accompanying drawings.
Fig. 1 is that box body of the present utility model is provided with the fixed groove and the fixing structural representation of hole clipping;
Fig. 2 is box body assembly assembly 001 structural representation of the present utility model;
Fig. 3 is a photovoltaic junction box overall structure schematic diagram of the present utility model.
Embodiment
For the ease of understanding the utility model patent, the spy is further described in conjunction with embodiment, but present embodiment should not regarded any restriction to the utility model patent as.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, a kind of solar photovoltaic assembly terminal box comprises box body 1, box body assembly assembly 001, lid 10; Described box body 1 bottom is provided with 4 place's fixed grooves 12, and fixedly hole clipping 13 of 4 places is arranged in fixed groove 12; 4 elastic clips 2 pass corresponding fixedly hole clipping 13 and are fixed together with box body 1 and constitute box body assembly assembly 001 in fixed groove 12; Bypass diode 5 and connection fittings are fastened on the lid 10, and the box body barricade 19 of PPO material has been installed in the left and right sides of box body 1.
Photovoltaic junction box of the present utility model has following 2 characteristics:
1, bypass diode 5 and connection fittings are connected on the lid 10, and box body 1 is fixed on the assembly as support, when terminal box breaks down, just repair or replace and can deal with problems as long as take off lid 10. 2, at the left and right sides of box body 1 house ornamentation the box body barricade 19 of insulation of PPO material, both sides also have been installed by the insulation barrier of PPO material up and down at box body, strengthen with this and to climb leakage distance, better prevented static, strengthen simultaneously the impact strength of terminal box.
