[0084] Change the copper tube in Example 1 into a copper alloy tube, and change the aluminum rod into an aluminum alloy rod. Because the hardness of the alloy is relatively high, the aluminum alloy rod can be stored for a period of time (5 minutes) in a low temperature environment (5 degrees). ), and the copper alloy tube is stored in a high temperature environment (80 degrees) for a period of time (5 minutes), with the help of thermal expansion and contraction effect, the inner diameter of the copper alloy tube can be slightly larger, while the outer diameter of the aluminum alloy rod is slightly smaller , and then conveniently assemble the aluminum alloy rod into the copper alloy tube. After the assembled connecting column returns to normal temperature, the copper alloy tube and the aluminum alloy rod can achieve interference fit. The diameter and length of the coupling column disclosed in the present invention have different specifications to meet the needs of different busb...
