Title:
ELECTRIC ENERGY TRANSMISSION ALUMINUM PART AND MACHINING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/197422
Kind Code:
A1
Abstract:
Disclosed are an electric energy transmission aluminum part and a machining process therefor. The electric energy transmission aluminum part comprises an aluminum conductive device (1) and an aluminum cable, wherein the aluminum cable comprises an aluminum conductive core (2) and an insulating layer (3) wrapped around a surface of the aluminum conductive core (2), and a section of the aluminum conductive core (2) of the aluminum cable which is exposed where the insulating layer (3) is stripped, and the aluminum conductive core (2) at least partially provided with the insulating layer (3) are crimped in the aluminum conductive device (1); and a transition section (4) with a trapezoidal axial section is arranged at a junction between the insulating layer (3) and the exposed aluminum conductive core (2) in the aluminum conductive device (1). Taking the transition section (4) as a demarcation point, an inner diameter of an end of the aluminum conductive device (1) that is crimped with the insulating layer (3) is greater than an inner diameter of an end of the aluminum conductive device (1) that is crimped with the aluminum conductive core (2), and at least one concave structure is arranged on the periphery of the aluminum conductive device (1). The concave structure is arranged on a surface of the aluminum conductive device (1), such that the aluminum conductive device (1) can be effectively prevented from moving relative to a clamp, the problem of the aluminum conductive device (1) being displaced or rotated in the clamp during welding is solved, and the welding efficiency and the yield are improved.
