<p>PROBLEM TO BE SOLVED: To provide a terminal connection device which allows for easy visual confirmation of whether a bolt for directly fastening the conductive connection of a terminal block is in a state of sufficiently fastened.SOLUTION: On an insulating terminal block 11, terminal conductors 12, 13 to be connected each other are superposed, and then they are fastened directly by means of a bolt 15 and connected. In such a terminal connection device, a display body 17 capable of changing the display form, depending on the fastening state therebetween, is provided on the side of a portion of the terminal block 11 where the terminal conductors 12, 13 are connected. Between the tip of the bolt 15 and the display body 17, a drive mechanism 18 for changing the display form, when the bolt 15 reaches a predetermined fastening position for fastening between the terminal conductors with a specified pressure, is constituted.</p> |
