Abstract
An aluminum terminal includes an insertion cavity for inserting the aluminum wire. The insertion cavity includes a first cavity with an inner diameter matching with an outer diameter of the conductor core of the aluminum wire, and a second cavity with an inner diameter matching with an outer diameter of the insulation layer of the aluminum wire. The rear end of the first cavity is connected to the front end of the second cavity. The minimum wall thickness of the insertion cavity is not less than ⅙ times the wall thickness of the insulation layer. The copper-aluminum transition connector includes the copper terminal and at least one aluminum terminal. The copper terminal is fixed on the front end of the first cavity of the aluminum terminal.
