The inventor finds that the materials commonly used for terminal screws, such as iron-plated zinc, stainless steel, copper-plated zinc and aluminum, have the following differences in application: the iron galvanized screw has stronger magnetism; the stainless steel screw is generally made of 304 stainless steel, and does not have magnetism, but the stainless steel can generate phase change due to deformation in the processes of stamping, stretching, rolling and dane cold working, so that certain magnetism is generated, and the 304 stainless steel which is not demagnetized can have weak magnetism; the copper galvanized screw has the best performance and is not easy to rust, when the coating is damaged and rusted, copper oxide formed is still good in conductivity, the copper galvanized screw is non-magnetic, and the color of the internal copper simple substance is purple red or golden yellow after being sheared; the aluminum screw has the defects of poor structure, soft material, easy fracture, poor conductivity of generated aluminum oxide, small volume and mass, and fast formation of an aluminum oxide protective layer in a dark gray state.

The utility model provides a terminal screw is material differentiateed appearance commonly used can differentiate the screw of terminal box fast, judges the screw material that the terminal box of firm production used. When the device is used, the test probe 2 is close to the terminal screw, if the display module 4 displays a larger numerical value, the pressure sensor 21 is indicated to be subjected to a larger pressure value, and the terminal screw is an iron galvanized screw; if the display module 4 displays a smaller numerical value, the terminal screw is a stainless steel screw; if the value displayed by the display module 4 is zero, the display module is a copper galvanized screw or an aluminum screw. That is, the terminal screw common material discriminator provided by the application can rapidly distinguish the screw material types, and iron screws and stainless steel screws are excluded; the copper galvanized screw and the aluminum screw can be distinguished by observing the internal color after the surface coating is damaged.
