Abstract

An electrical connection terminal includes a crimping part having a base with a front end and a rear end and a pair of opposite sides, a plurality of conductive teeth connected to the opposite sides of the base, and a plurality of fixing teeth connected to the opposite sides at the front end of the base. The electrical connection terminal has a main body connected to the rear end of the base. The conductive teeth pierce an insulator of a flexible electrical connection piece and are crimpable onto a conductor of the flexible electrical connection piece to be electrically connected to the flexible electrical connection piece. The fixing teeth pierce the insulator of the flexible electrical connection piece and are crimpable onto the insulator of the flexible electrical connection piece to fix the front end of the base to the flexible electrical connection piece.
