The utility model provides a terminal block and an electrical equipment system connected with the terminal block in order to prevent bad conditions of heating and the like in a poor connected terminal block along with a cable terminal in wiring operation and enable an operator to uniquely recognize defects of the connection torque of a connecting screw which connects the cable terminal to the terminal block. A restricting component is configured between a conductive portion of the terminal block and the connecting screw, a main body portion of the restricting component is enabled to incline by an ascending grade from a fixed portion relative to the conductive portion, an open end of a driven piece of the restricting component falls near a shaking pivot of an enclosure under a circumstance that the connecting torque of the connecting screw reaches a set value, thereby being capable of closing the enclosure. On the other hand, under a circumstance that the connecting torque of the connecting screw does not reach the set value, insufficiency of the connecting torque of the connecting screw can be recognized because the open end of the driven piece of the restricting component pushes the reverse side of the enclosure and a force is applied in the direction of preventing the enclosure from being closed. |
