Claims

[Scope of utility model registration request]

In the mold case, one end is open and a linear groove is provided inside two opposing sides perpendicular to the open end, and both ends of a printed circuit board on which electronic components are mounted are inserted into the groove and fixed. A molded case characterized in that at least one protrusion is provided which comes into contact with the printed circuit board and prevents the printed circuit board from being inserted when the printed circuit board is inserted with its front and back reversed.
