The present invention relates to a terminal block for earthing, and the block comprises: a conductive connecting strip, which comprises a first orifice; a conductive clamping piece, which is arranged on a conductive supporting guide rail and comprises a second orifice; a conductive clamping screw, which is arranged to fix the conductive clamping piece to the supporting guide rail. The clamping screw comprises a screw head of which diameter is greater than the diameter of a tapping of the first orifice of the connecting strip; a first portion, which comprises: the length is determined and extended from the screw head, the diameter of the first portion is less than the diameter of the tapping of the first orifice of the connecting strip, so that the first portion can freely slide in the first orifice; a second portion, which comprises: an end opposited to the screw head extends from the first portion to the screw, the length of the first portion is determined through the way therein, that is, when a tapping of the second orifice of the clamping piece is fitted to the screw of the second portion, the tapping of the first orifice of the connecting strip faces to the first portion of the clamping screw. The invention also relates to a method for assembling the terminal block for earthing. |
