<p>PURPOSE:To provide an earth terminal which is resistive to damage and assures loading and unloading of electrode portions only with one small screw and easier leading of an earth wire. CONSTITUTION:A cylindrical frame body 1 having apertures at both foreard and backward portions is formed by coupling a conic trapezoidal longitudinal cylindrical part 2 to cylindrical aperture receptable 3 for insertion of a disk type terminal cap 6. Thereby the frame body 1 is buried in communication with the hollowed inside of a concrete pole P and a terminal 7' for engaging with the earth wire A' is provided at the rear surface of the terminal cap 6. Moreover, one small screw is inserted to the terminal cap 6 from the front surface and it is then screwed with a nut 16 at the rear surface of the terminal cap 6. Simultaneously, the control pieces 17, 17 projected in both sides are applied to the nut 16, these control pieces open following the tightness of nut 16 until these are elastically engaged, by its spring function, with the internal wall opposed to the frame body 1, thus fixing the terminal cap 6 to the aperture receptacle 3.</p> |
