s3: and (3) detection: connecting a 15V power supply to the transverse copper sheet (18) and the longitudinal copper sheet (19), measuring the supporting legs (2) by using a universal meter, and detecting whether current passes through;
s4: punching: four corners of a cross intersection of the transverse copper sheet (18) and the longitudinal copper sheet (19) are provided with first threaded holes (20), the first threaded holes (20) are formed in the cabinet body (1), a first through hole (21) is formed in the U-shaped cold-rolled hard plate (11), second through holes (22) are formed in the periphery of the front surface of the conductive post (10), and the middle end of the front surface of the conductive post (10) is provided with a second threaded hole (23);
s5: installation: placing a conductive column (10) at the joint of a transverse copper sheet (18) and a longitudinal copper sheet (19) and contacting with the transverse copper sheet (18) and the longitudinal copper sheet (19), aligning a second through hole (22) on the conductive column (10) with a first threaded hole (20), fixing the conductive column (10) in the second through hole (22) by penetrating through the second through hole (22) and the first threaded hole (20) through a bolt, contacting the outer side surface and the bottom surface of a U-shaped cold-rolled hard board (11) with the conductive column (10), aligning a first through hole (21) on the U-shaped cold-rolled hard board (11) with a second threaded hole (23) on the conductive column (10), and fixing the U-shaped cold-rolled hard board (11) on the conductive column (10) by penetrating through the first through hole (21) and the second threaded hole (23) through an inner hexagonal bolt;
s6: film covering: the left side surface, the right side surface and the bottom surface of the inner cavity of the U-shaped cold-rolled hard plate (11) are covered with a layer of anti-static paster (12).
