Electromagnetic relay

The invention discloses an electromagnetic relay, which comprises a shell, a load terminal extending outwards from the inside of the shell, and a screw used for connecting a customer installation copper bar or a wiring terminal to the part, outside the shell, of the load terminal, the screw is matched on the part, outside the shell, of the load terminal and locks the copper bar or the wiring terminal on the part, outside the shell, of the load terminal; the screw is also connected with an internal thread structure part; the internal thread structure part is matched with the screw in a screwed mode, and the internal thread structure part is matched with the shell in an anti-rotation mode. According to the invention, the stress concentration phenomenon in the installation process of the load terminal and the client installation copper bar or the wiring terminal can be eliminated, and the phenomenon that the relay loses efficacy due to the change of relay contact parameters caused by the deformation of the load
