Embodiment
For the ease of understanding the utility model, the spy is further described in conjunction with embodiment, but present embodiment should not regarded as any restriction of the present utility model.
In conjunction with each accompanying drawing, a kind of terminal box that is used for solar module comprises housing 14, loam cake 13, diode 3, is arranged at binding post 11 and support arm 9 and inner support 10 in the housing 14; Around the edge, inside of loam cake 13, a sealing ring 1 is arranged, be fixedly connected on the inner support 10 with screw 5 again after described binding post 11 adopts flat inserting mode to be connected support arm 9.Described diode 3 adopts pin to peg graft with last spring 6 and the scolding tin welding manner is connected on the inner support 10.Described support arm 9 and inner support 10 have up an open slot, support arm 9 with inner support 10 clampings in aggregates after, housing 14 is close in the bottom of inner support 10.Described housing 14 has groove, is inlaid with radiator 12 at this groove.
When mounted, radiator 12 connects together with housing 14 by injection moulding; Then U type shell fragment 7 is contained in the triangular spring 8, then the triangular spring 8, support arm 9, the inner support 10 that install is installed on the housing 14; Binding post 11 inserts binding post 11 in the support arm 9 by connecting together with cable 4 punching presses again, fixes by screw 5 again; Then last spring 6 is put into respectively in support arm 9, the inner support 10; The pin of diode 3 is plugged between spring 6 support arms 9, the inner support 10; Then load onto T RunddichtringO 2, the gaily decorated basket 15, on cover 16, nut 17; At last the loam cake 13 of loading onto sealing ring 1 is incorporated on the housing 14, promptly finishes the assembling of terminal box.
When mounted:
1. terminal portions adopts flat grafting, is fixedly coupled mode with screw again.The conductor contact-making surface is increased, reduce contact resistance, increase heat transfer property.
2. the connection of diode adopts pin to peg graft and the scolding tin welding manner, avoided because of the vibrations in the handling process, or work in the open air for a long time, and make bypass diode the situation of loose contact occur, improved the functional reliability of this terminal box, increase contact area simultaneously, promoted electric conductivity and heat transfer property.
3. the terminal box base is inlayed radiator; radiator and box body bottom are injection molded into one; being designed to the trip form on the radiator simultaneously prevents under the radiator high-temperature condition bad in conjunction with effect; on the basis of existing photovoltaic terminal box, set up radiator; so that in time reduce the temperature of box internal heat generation device; prolonged the useful life of terminal box, more effective protection solar panel.
