Split type conductive cylinder, round copper arm and aluminum arm connecting structure

The utility model relates to a split type conductive cylinder, round copper arm and aluminum arm connecting structure, which comprises a conductive copper sleeve and a water through block, the conductive copper sleeve is of a hollow structure, a plurality of strip-shaped grooves are arranged on the peripheral side of the conductive copper sleeve, the strip-shaped grooves are circumferentially distributed around the central axis of the conductive copper sleeve, a boss is arranged at the front end of the water through block, and the boss is in threaded connection with the rear end of the conductive copper sleeve. A circulating water channel is arranged in the water passing block, the split type conductive barrel is formed by connecting the conductive copper sleeve and the water passing block which are machined separately in a threaded mode, and compared with an integrated structure in the prior art, the conductive copper sleeve and the water passing block can be machined by selecting different materials and the
