WIPO Patent Application WO/2021/088193
Kind Code:
A1
Abstract:
Disclosed are a connection structure (100) of a mutual inductor (1) and a wiring terminal (3), a manufacturing method therefor, and an instrument (40) therewith. The connection structure comprises the mutual inductor (1), a primary current line (2) and the wiring terminal (3). One axial end of the wiring terminal (3) is provided with a connection hole (321) used for being in abutment joint with the primary current line (2), the other axial end of the wiring terminal (3) is provided with a wiring hole (315) used for external electrical connection, and an inner side wall (322) of the connection hole (321) of the wiring terminal (3) is provided with meshing teeth (323); the mutual inductor (1) is sheathed outside the primary current line (2); and the primary current line (2) is inserted into the connection hole (321), the hardness of the meshing teeth (323) is greater than the hardness of the primary current line (2), and after the connection hole (321) of the wiring terminal (3) is pressed by an external mechanism, the meshing teeth (323) are pressed inward and then the primary current line (2) is completely embedded therein, thereby achieving or being close to zero resistance contact.
