Abstract
The utility model relates to a novel solar energy junction box, which comprises a box body and a box cover, wherein a connecting hole is arranged at the side surface of the box body. The utility model is characterized in that the box body is internally provided with a printed circuit board with a solar power controller circuit, and the box cover is provided with an operating button and a display screen of the solar power controller. Compared with the prior art, since the solar energy junction box and the solar power controller are integrated by the utility model, the solar power controller and a power generation unit electrode of the solar cell panel which is led inside the junction box can be connected electrically in advance. During the on-site assembly, the only thing needed to be done is to connect the guide line led from the junction box to a storage battery and a load line, therefore, the utility model has the advantages that not only the structure is compact, but also the assembly speed is greatly quickened when a solar energy power device is arranged on the scene, thus the working efficiency is high; and the operation can be operated without professional staff, even an ordinary user can conveniently carry out the operation, thus the novel solar energy junction box is more enjoyable by the user.
Description
Technical field
The utility model relates to a kind of electrical junction box, specifically refers to a kind of solar junction box that is installed in Solar panel backside.
Background technology
Along with reducing of global warming and petroleum storage amount, solar energy power source apparatus is widely used in the different field as a kind of alternative eco-friendly power source.Existing solar energy power source apparatus generally comprises solar panel, controller and storage battery, wherein, the back side of solar panel is equipped with terminal box, this terminal box includes box body and lid usually, as Chinese patent mandate public rights accuse number " off-grid type solar panel control terminal box " for CN201327977Y just disclosed so a kind of terminal box, at least one side at the box body of this terminal box is distributed with wiring hole, each side of all the other of terminal box box body is distributed with the wiring preformed hole, be distributed with the wiring grid in the terminal box box body, be distributed with wire guide plate on the wiring grid, a termination of wire guide plate is inserted with anti-lock device.When dispatching from the factory assembling, after the electrode of the generator unit in the solar panel is integrated, cause on the end of the corresponding lead plate in this box body.And the wiring when the assembled in situ of the other end of wire guide plate, so that be connected in controller or other solar panel or the load.
Because present solar panel, controller and storage battery is separate installation, be electrically connected very irregular, when therefore assembling at the scene, not only need the professional to finish, and usually be subjected to the restriction of erecting bed, and causing difficult wiring, installation effectiveness is low, while is utmost point waste leading wire material also, thereby has increased installation cost to a certain extent.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, a kind of novel solar junction box is provided, this solar junction box can make the solar energy power source apparatus compact conformation, be electrically connected convenience during on-the-spot the installation, thereby can improve the installation effectiveness of solar energy power source apparatus significantly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this novelty solar junction box comprises box body and lid, have wiring hole on the side of box body, it is characterized in that: the printed circuit board of band controller for solar circuit also is installed in the described box body, and described lid is provided with the action button and the display screen of controller for solar.
In order to prevent to intake in the terminal box, can also be provided with sealing ring on the contact-making surface between described box body and the lid.And the sealing circle can be provided with as follows: be provided with seal groove on box body, sealing ring is embedded in the sealing groove.Certainly, also can design seal groove on lid, sealing ring is embedded in the seal groove on lid, such structure can realize the function that seals equally.
Practical is charging indicator light and discharge indicator light to be installed, so that know the operating state of storage battery intuitively on the described lid.
Compared with prior art, because the utility model has the printed circuit board of controller for solar, be that solar junction box and controller for solar unite two into one and make integral piece, therefore, can in advance controller for solar and the generator unit electrode that causes the solar panel in the terminal box be electrically connected, and when assembling at the scene, as long as the lead of drawing in the wiring hole is connected to storage battery and load, so the utility model not only makes compact overall structure, and when at the scene solar energy power source apparatus being installed, accelerated assembling speed widely, make the operating efficiency height, need not professional's operation again, connecting ordinary consumer can both conveniently implement, thereby more is subjected to liking of people.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this solar junction box comprises box body 1 and lid 2, have two wiring holes 3 on the side of box body, the printed circuit board 4 of band controller for solar circuit is installed in the box body, the panel 5 of lid is provided with the action button and the display screen 6 of controller for solar, wherein action button is formed by setting button 7 and on/off button 8, also is provided with charging indicator light 9 and discharge indicator light 10 simultaneously on lid.Controller circuitry on the printed circuit board of mentioning in the present embodiment can adopt prior art; have load short circuits protection and reverse connecting protection function; it and action button, display screen 6, charging indicator light 9 and being electrically connected between the indicator light 10 of discharging are routine techniques, launch explanation no longer in detail at this.
In order to prevent to intake in the terminal box, on the contact-making surface between box body and the lid, also be provided with sealing ring 11.Here, box body is provided with seal groove 12, and sealing ring 11 is embedded in seal groove.
Above-mentioned terminal box is bonded in the back side of solar panel 13 by silica gel, sees also Fig. 2, to play better waterproof action.Be electrically connected routinely between terminal box after the installation, controller for solar and the solar panel, and then from two wiring holes of box body side, draw cable respectively with two leads.When install at the scene, connect load 17 and get final product as long as first cable 14 is connect storage battery 16, the second cables 15, see also Fig. 3 and Fig. 4.
When the solar energy power source apparatus after the above-mentioned installation used, daytime, solar panel generated electricity under the irradiation of sunlight, and electric current charges to storage battery through the controller in the terminal box, and at this moment, charging indicator light is bright; When the voltage of storage battery is charged to a certain degree (in the present embodiment, storage battery overcharge a little to 13.8V the time), controller is just controlled solar panel and is stopped to charge a battery, at this moment, charging indicator light goes out.When load needs electricity consumption, the electricity of storage battery arrives load through controller, the indicator light that discharges this moment is bright, along with the electricity consumption of load, the voltage of storage battery descends gradually, when voltage drops to a certain degree (in the present embodiment, when the mistake of storage battery is put a little for 11.8V), controller is just controlled storage battery and is stopped powering load, and at this moment, the discharge indicator light goes out.Go round and begin again like this, be embodied as the purpose of electric.
