Description

Solar assembly junction box

Technical field

The utility model relates to terminal box, relates in particular to a kind of solar assembly junction box.

Background technology

Traditional solar assembly junction box generally is made up of box body, lid and sealing ring, adopts screw to twist between box body and the lid and closes connection, and whole terminal box is a complete seal.Though such junction box structure has guaranteed favorable waterproof property, but also has big hidden danger, because absorbing sunlight, the solar components panel is converted into electric energy, surface temperature is very high, and be positioned at the solar assembly junction box at the solar components back side, especially when the interior diode adstante febre of box, it is very frequent that gas in the box expands with heat and contract with cold, if can not in time dispel the heat, terminal box distortion or the phenomenon of breaking just appear easily, badly influence the useful life of terminal box, and traditional solar components plastic junction box is difficult to bear the pressure imbalance that shock heating quenching causes; On the other hand, in case cause thermal damage appearred in the diode in the box, just have to whole terminal box is disassembled the replacement maintenance of carrying out diode from the solar components panel, because box body and lid screw syndeton make that the dismounting of terminal box is too loaded down with trivial details, also cause wearing and tearing easily in disassembly process.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of solar assembly junction box is provided.

Solar assembly junction box comprises wiring master box A and diode seal box B, wiring master box A comprises lead-out wire, buckle, lower contact, groove, lead-in, conductive copper sheet, screw, structural plastic, wiring master box housing, plastics pylon, sealing ring and metal joint, the conductive copper sheet of wiring master box enclosure interior is screwed on structural plastic, and the both sides of wiring master box housing are respectively equipped with lead-in and lead-out wire; Wiring master box back side of shell has groove, and the groove inwall is provided with buckle, and groove floor is distributed with lower contact, and this lower contact is made up of plastics pylon, sealing ring and metal joint; Diode seal box B comprises fixture block, fin, top connection, diode, insulating radiation layer, following heat-conducting plate, goes up heat-conducting plate, sealing lid, diode seal box housing and circular groove; Diode seal box hull outside is distributed with two row fin, and be provided with the fixture block that docks with buckle, diode seal box housing bottom surface is provided with the top connection that matches with lower contact, diode seal box enclosure interior diode is surrounded by one deck insulating radiation layer outward, and the insulating radiation layer is embedded in down in the circular groove between heat-conducting plate and the last heat-conducting plate; Case bonding becomes seal to the sealing lid with the diode seal box.

The utility model combines the characteristics of existing solar assembly junction box, and improve the deficiency of its existence, solar assembly junction box is designed to separate type, i.e. solar components wiring master's box and diode seal box can disassembled and assembled freelies, connect by the fixture block buckle structure.The main heat generating components of solar assembly junction box is diode, and the junction box structure after the improvement makes diode seal box controllability is strengthened that the maintenance dismounting is convenient, and has improved the heat dispersion of terminal box.In case the cause thermal damage phenomenon occurs, only need unload the diode seal box keeps in repair replacement, and needn't pull down wiring master box, has effectively avoided the wearing and tearing of dismounting solar assembly junction box to parts.In addition, in case after terminal box master box and solar panel were adhesively fixed, terminal box master's box was sealed-for-life, effectively strengthened the sealing of terminal box master's box.The utility model is simple in structure, easy to operate, be convenient to keep in repair dismounting, its cleverly structural design improved the heat dispersion of solar assembly junction box, and prolonged the useful life of solar assembly junction box.
