Reliable welded solar PV modules terminal box

The utility model relates to a reliable welded solar PV modules terminal box, including the terminal box body, this internal sheetmetal lead -out wire that is equipped with of terminal box is equipped with the recess on the sheetmetal lead -out wire, be equipped with the solder joint in the recess. When need be with solar cell's output during with the welding of sheetmetal lead -out wire, the solder joint after the melting be deposited and is put in the recess, can be along the trickling of sheetmetal lead -out wire, make the abundant welding of solder joint take welding, firm connection solar cell's output and sheetmetal lead -out wire, avoided rosin joint and welding spot drop's phenomenon, messenger circuit connection is more reliable.
