Abstract
The utility model relates to an improved solar photovoltaic junction box which comprises a bottom box and a box cover arranged on the bottom box, wherein the box cover is provided with a ventilation hole, and a ventilation film is covered on the ventilation hole. By arranging the ventilation hole and the ventilation film, the high temperature in the box can be emitted through the ventilation film; and since the ventilation film is waterproof, the air temperature and the air pressure in the box are lowered, thereby protecting the diode and avoiding the phenomenon of box explosion.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box, relates in particular to the improvement of butted line box lid.
Background technology
When working in the photovoltaic junction box, can produce certain heat, heat causes temperature rising in the box; And photovoltaic junction box is a seal closure in the prior art, and heat can't discharge, and the phenomenon of thermal explosion box can take place; Not only damage terminal box, also produce certain danger.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of a kind of improved photovoltaic terminal box that can heat discharge in the box be gone out.
The technical scheme that the utility model solves its technical problem is:
A kind of improved photovoltaic terminal box comprises end box and is arranged on the lid on the end box that described lid is provided with air-vent, is coated with ventilated membrane on the described air-vent.
Be provided with crimp groove around the described air-vent, a crimp band can be pressed in the described crimp groove, and described ventilated membrane is fixed on the air-vent through crimp band.
Described air-vent is provided with several, is arranged in circle, and described crimp band is connected in the crimp groove through supersonic welding.
Air-vent is set on lid; And be coated with ventilated membrane on the air-vent, ventilated membrane can be with outside the heat delivery cassette, but hydrone can't get into again; It promptly is waterproof; The high temperature that the corresponding diode of photovoltaic junction box produces during through electric current is through ventilated membrane effectively outside the delivery cassette, thereby makes interior temperature of box and air pressure decline, effectively avoided the generation of thermal explosion box.Air-vent can be arranged to a plurality of and be arranged in circle according to certain rules, be fixed in the crimp groove through a crimp band, and crimp band and crimp groove is connected together through supersonic welding, and is solid and reliable.
The beneficial effect of the utility model is: the utility model is through the setting of air-vent and ventilated membrane; Make that the high temperature in the box can be through the ventilated membrane discharging, and ventilated membrane is waterproof, thereby makes the gentle drops of temperature in the box; The protection diode has been avoided the generation of quick-fried box phenomenon.
Description of drawings
Fig. 1 is that the solid of the utility model guarantees structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1; A kind of improved photovoltaic terminal box comprises end box and is arranged on the lid 5 on the end box that lid is provided with several air-vents 3; Air-vent 3 is arranged in circle according to certain rule; Be coated with ventilated membrane 2 on the air-vent, ventilated membrane 2 is circular, and one whole covers on all air-vents.Being provided with crimp groove 4, one crimp band 1 around the air-vent 3 can be connected in the crimp groove 4 through supersonic welding, and then ventilated membrane 2 is fixed on the air-vent through crimp band 1.
Air-vent 3 is set on lid; And be coated with ventilated membrane 2 on the air-vent 3, ventilated membrane can be with outside the heat delivery cassette, but hydrone can't get into again; It promptly is waterproof; The high temperature that the corresponding diode of photovoltaic junction box produces during through electric current is through ventilated membrane effectively outside the delivery cassette, thereby makes interior temperature of box and air pressure decline, effectively avoided the generation of thermal explosion box.Air-vent can be arranged to a plurality of and be arranged in circle according to certain rules, be fixed in the crimp groove 4 through a crimp band 1, and crimp band and crimp groove is connected together through supersonic welding, and is solid and reliable.
