Wiring copper bar with stable connection

Abstract

The utility model relates to the technical field of wiring copper bars, in particular to a wiring copper bar stable in connection, which comprises a plurality of fixing columns in screwed connection with the bottom end of a threaded column through bearings, and sliding grooves are formed in the side walls of the fixing columns. The plurality of positioning columns are fixedly arranged below the copper bar body respectively, the fixing columns are movably inserted into the positioning columns, and buckles are arranged at openings of the positioning columns and arranged in the sliding grooves in a sliding mode; the limiting blocks are fixedly arranged at the bottom end of the fixing column, the limiting rods are movably inserted into the side wall of the positioning column at equal intervals through first springs, the two ends of the first springs are connected with the side wall of the positioning column and the limiting rods respectively, the ends of the limiting rods movably abut against the top faces of the limiting blocks, and inserting holes are formed in the side walls of the limiting rods. The limiting rod and the limiting block are matched to fix the limiting block in the positioning column, so that the movement of the threaded column is limited, the threaded column is prevented from loosening, and the stability of wiring connection is improved.
