Electrical terminal fastening dies for fastening a conductor to a terminal

摘要

Electrical terminal fastening dies are provided, which includes: an electric wire; an electrical terminal having the electric wire; a couple of dies to press the electrical terminal a substantially hexagon in cross section; an abutting plane provided on each of the couple of dies; a pressing groove provided on the abutting plane and having a section to be formed by dividing a hexagon symmetrically with a diagonal; a pair of terminal pressing planes formed on a surface of the pressing groove of at least either one of the couple of dies for pressing the electrical terminal; and a pair of flash preventing planes formed on the surface of the pressing groove having the pair of terminal pressing planes, and each connected to the abutting plane, for pressing the electrical terminal to form thin portions thereon so as to prevent a flash from arising on the electrical terminal. Further, an electrical terminal fastening method is provided, which includes the steps of: inserting an electric wire into an electrical terminal; putting the electrical terminal between pressing grooves formed on a couple of dies; and pressing the electrical terminal a substantially hexagon in cross section by the couple of dies so as to fastening the electrical terminal to the electric wire.
