Title:
ALUMINUM TERMINAL AND COPPER-ALUMINUM TRANSITION CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2018/082486
Kind Code:
A1
Abstract:
An aluminum terminal and a copper-aluminum transition connector. An aluminum terminal (1) comprises an insertion cavity for the insertion of an aluminum wire (2); the insertion cavity comprises a first cavity (11) having an inner diameter matching an outer diameter of a core (21) of the aluminum wire (2), and a second cavity (12) having an inner diameter matching an outer diameter of an insulating layer (22) of the aluminum wire (2); a rear end of the first cavity (11) is connected to a front end of the second cavity (12); the minimum wall thickness (H) of the insertion cavity is not less than 1/6 of the wall thickness of the insulating layer (22). A copper-aluminum transition terminal comprises a copper terminal (3) and at least one aluminum terminal (1); the copper terminal (3) is fixed to the front end of the first cavity (11) of the aluminum terminal (1). The present solution can not only prevent cracks on the aluminum terminal (1) during a press bonding process and facilitate the rationalization of costs of a finished product, but also improve the conductive performance between the aluminum terminal (1) and the aluminum wire (2).
