The top of described box body can be provided with annular groove, is used to place described sealing ring.
The lead-out wire of photovoltaic module and conductive component connect back encapsulating encapsulation process, make output not have electric spark to occur fully; Simultaneously, the appearance structure of terminal box all has thickening and increases design, makes it firmer, safer, is applicable to the hazardous area.
Further technical scheme all is parallel with another diode on each diode in the described protective circuit of diode, constitutes the double diode protective circuit.If diode cisco unity malfunction wherein, another can guarantee under the hot spot state assembly to be played the bypass effect too, and it is minimum also to help the joint temperature of diode under in working order simultaneously.
In the technique scheme, described fluid sealant is an AB glue.As 1521 AB glue.
In the technique scheme, described radiator structure comprises at least 2 radiating ribs, and radiating ribs is distributed in the side of box body.Also can adopt other prior radiating structure,, help internal heat dissipating as radiator shutter.
Further technical scheme, a side of described box body is provided with 2 cable leadout holes, and the side that two other of box body is relative respectively is provided with 1 cable leadout hole.Thereby constitute 4 cable leadout holes, the outlet that is about to lead-out wire is distributed in the bottom and the left and right sides of box body, can carry out the lead-out wire direction according to client's needs and select.
In the technique scheme, the top of described box body is provided with screwed hole for four jiaos, and lid is provided with the screw of cooperation, and both are threaded.Adopt the mounting means of screw, and use the sealing of foamed silica gel sealing ring, reach the instructions for use of IP65 fully.
In the technique scheme, described electric conductor and box body are the branch body structures.Thereby make the mould structure of exploitation simple, long service life.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is provided with sealing ring between box body and lid, and after connecting, the lead-out wire of photovoltaic module and conductive component carry out the encapsulating encapsulation process, make and be filled with fluid sealant in the box body, thereby make photovoltaic module reach the instructions for use of IP65 fully, make output not have electric spark to occur fully, make this terminal box can be applicable to explosion-proof place, as hazardous areas such as oil field, gas station, gas stations.
, since the utility model in box body, be filled with fluid sealant, simultaneously, in order to increase the solidness of terminal box, its box body and lid all have thickening and increase design, cause the heat dispersion of terminal box relatively poor, influenced its normal use, therefore, on the side of box body, radiator structure is set, strengthens the volume of terminal box simultaneously, improve its heat dispersion, guarantee the normal use of terminal box.
, the utility model is provided with the double diode protective circuit, even therefore diode cisco unity malfunction wherein, another can guarantee under the hot spot state assembly to be played the bypass effect too, it is minimum also to help the joint temperature of diode under in working order simultaneously.
, the utility model is provided with 2 cable leadout holes in a side of box body, the side that two other of box body is relative respectively is provided with 1 cable leadout hole, thereby constitute 4 cable leadout holes, the outlet that is about to lead-out wire is distributed in the bottom and the left and right sides of box body, can carry out the lead-out wire direction according to client's needs and select.
, the utility model is simple in structure, is convenient to preparation, be suitable for applying.
