Abstract
The utility model discloses a solar energy photovoltaic terminal box which comprises an upper cover, a shell, a diode and a conductive bar, wherein the upper cover is provided with a breathable film which is fixed on the upper cover by a breathable film sealing plug. The solar energy photovoltaic terminal box has the benefits of being good in radiation, preventing a solar energy battery plate from generating hot spot effect, tightly locking a busbar without the help of tools, having large lock force, being low in contact resistance and convenient in operation, buckling the upper cover by utilizing the diagonal bracing principle so as to avoid thermal deformation in long-term use, and preventing a water-proof screw nut from loosening in long-term use through locking the water-proof screw nut by utilizing the upper cover.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box.
Background technology
The photovoltaic terminal box is the critical component of solar panel energy output, the quality of its quality and performance directly has influence on the conversion efficiency of its energy, produce the product of the manufacturer production of photovoltaic terminal box at present, there is backward in technique, unstable product quality, the outstanding problem of its existence is: 1, terminal box internal temperature height, water resistance are poor, damage owing to the internal temperature height causes solar panel to produce hot spot effect, influenced the useful life of solar panel; The installation of the band that 2, confluxes need be big by instrument and the little contact resistance of contact area, causes heating to damage easily and increase resistance; 3, loam cake adopts loam cake to connect as the buckle of deformable body with being connected of housing mostly, is easy to just can open or loosening without instrument after thermal deformation after a while, causes the reduction or the inefficacy of water resistance; 4, the waterproof nut can not strike with the hand open easily in self-locking.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of photovoltaic terminal box.
To achieve these goals, technical solution adopted in the utility model is:
The photovoltaic terminal box comprises the fixed form of loam cake, housing, diode and busbar, and loam cake is provided with ventilated membrane, and ventilated membrane covers by stifled being fixed on of ventilated membrane sealing;
Photovoltaic terminal box bottom is provided with air-vent and heat dam;
Loam cake is provided with the heat radiation wing;
Diode by diode fixedly jump ring directly be fixed on the busbar, install simple, easy to maintenance, good heat dissipation effect;
The band that confluxes is fixed on the busbar by the conflux tight clip spring seat with lock and the tight jump ring with lock that confluxes, and coupling mechanism force is big, contact resistance is little;
Housing is provided with and is used for loam cake is fastened, avoids thermal deformation diagonal brace in long-term the use.
The beneficial effects of the utility model: good heat dissipation, can avoid solar panel to produce hot spot effect; Not need by instrument just can with conflux with lock tight, coupling mechanism force is big, contact resistance is little, easy to operate; Utilize the diagonal brace principle to fasten, avoided thermal deformation in the long-term use to cause the loosening disengagement of loam cake loam cake.Utilize loam cake to pin, avoided in the long-term use nut loosening on the waterproof nut.

Embodiment
See also its implementation process of description of drawings: the photovoltaic terminal box, comprise loam cake 1, housing 2, diode 32 and solar panel, loam cake 1 is provided with ventilated membrane 12, ventilated membrane 12 is fixed on the loam cake 1 by silicone rubber O-ring 11, ventilated membrane sealing ring 13 is arranged on the ventilated membrane 12, ventilated membrane protector 121 is arranged outside the ventilated membrane 12; Increase the ventilated membrane device, solved the high pressure cooker effect that forms of air pressure inside, utilize the exchange of inner air and outer air to reduce the interior temperature of terminal block housings.The solar panel bottom is provided with air-vent and heat dam 122.The bottom increases gas port and heat dam, stops the conduction of heat to solar panel, avoids solar cell to produce hot spot effect.Loam cake 1 is provided with heat radiation wing 5.Increased the area of dissipation good heat dissipation effect of loam cake.Diode by diode fixedly jump ring 31 can directly be plugged on busbar 3, and the height of busbar can effectively protect diode not to be damaged, and increases the thermal radiation capability of diode, reduces diode temperature (seeing Fig. 2-2); Busbar fixed screw 33, busbar fixedly camphane spare 23 are fixed on busbar in the housing.Conflux and be with 20 to be fixed on the busbar by the conflux tight clip spring seat with lock 21 and the tight jump ring 22 with lock that confluxes.Diode by diode fixedly jump ring 31,
Novel busbar structural design, protection diode are avoided accidental damage, reduction contact resistance, are strengthened the radiating effect of diode.Unique band chucking mode of confluxing, not need by instrument just can with conflux with lock tightly, coupling mechanism force is big, contact resistance is little, easy to operate.Housing has and is used for loam cake has been fastened, avoided thermal deformation diagonal brace 14 in the long-term use.Avoided the thermal deformation in the long-term use.Housing 2 is provided with waterproof lock nut 4.Utilize loam cake to pin, avoided in the long-term use nut loosening on the waterproof nut.
The protection range of this patent not only is confined to present embodiment, and some other simple modification and replacement all are the protection ranges of this patent.
