[0014] As Figures 1-4As shown, this utility model embodiment is an industrial adapter plug with a viewing window, including a housing 10, a screw cap 11 disposed on the housing 10, a locking nut assembly 20 disposed at the tail of the housing 10, and a plug assembly 30 disposed inside the housing 10. The plug assembly 30 includes a base 31 disposed inside the housing 10 and a plurality of plugs 32 disposed on the base 31. One end of each plug 32 has a plug portion 321 extending outside the base 31, and the other end of each plug 32 has a wiring groove 322. The insert 32 is provided with a wiring screw 33 corresponding to the wiring slot 322. The housing 10 is provided with two viewing windows 101 on both sides of the wiring screws 33 corresponding to the insert 32. Two transparent viewing sheets 12 are provided within the two viewing windows 101. Each transparent viewing sheet 12 has a protrusion 121 in its center that mates with the viewing window 101. The protrusion 121 fits into the viewing window 101, forming a sealed fit between the transparent viewing sheet 12 and the housing 10. Multiple protruding rings 122 are arranged in a ring array along the edge of the transparent viewing sheet 12. Multiple protruding strips 123 are respectively provided on the transparent viewing sheet 12, connecting the multiple protruding rings 122.
