る。 However, in such conventional technology, when there is engine vibration e, the terminal bolt b, round terminal A, and nut d vibrate together, but the electric wire c is attached to the round terminal A. Since the terminal A is connected, it does not vibrate in the same direction, but rotational torque acts around the terminal bolt b. In this case, the nut d is tightened, so do not turn it in the direction to tighten it further. , it has the disadvantage that it rotates only in the direction in which it loosens together with the terminal bolt b.

る。Effects of the Invention As described above, the present invention provides a terminal bolt inside a supporting part having a locking protrusion for preventing rotation around the periphery, and the electrical connection of a terminal having a wire connection part and an electrical contact part. A locking cap is provided with a coupling hole for the terminal bolt in the part thereof, and a detent cap capable of accommodating the electrical contact part therein and having a wire draw-out part on the peripheral wall that engages with the wire connection part. Since it is equipped with a joint and a nut for tightening, the anti-rotation cap prevents the terminal from rotating even in the event of vibration, preventing the nut from loosening, thereby preventing poor contact of the terminal. By changing the circumferential position of the anti-rotation cap, the wire extraction position at the terminal can be easily changed, and features include no need to provide a special anti-rotation structure for the bolt. has.
