Description

Technical Field

[0001] This utility model relates to a coil, specifically a novel inductor coil. Background Technology

[0002] An inductor is a coil made by winding a conductor (usually enameled copper wire) one turn after another. To increase its inductance or achieve a specific function, a magnetic core of a specific shape (such as ferrite, silicon steel sheet, iron powder core, etc.) or a non-magnetic material core (such as plastic, ceramic, air) is often inserted inside the coil. The magnetic core can concentrate the magnetic field and significantly increase the inductance.

[0003] Existing inductor coils have complex structures and unreasonable designs, typically featuring only single-axis or dual-axis coils. In practical applications, they cannot achieve three-dimensional magnetic field control, and the accuracy of magnetic field control is generally poor, with limited ability to adjust the rate of change of magnetic flux. This results in poor adaptability to actual scanning requirements. Furthermore, the compatibility between the magnetic core and the base of the inductor coil is poor, leading to an unstable structure that fails to provide stable support for the coil during subsequent use. Therefore, the inventors have improved the structure of the inductor coil. Utility Model Content

[0004] The purpose of this invention is to provide a novel inductor coil. This inductor coil features a simple and reasonable structure. Thanks to the design of X-axis, Y-axis, and Z-axis coils, which are fixed to the magnetic core structure, it can independently or in combination generate gradient magnetic fields in any direction, achieving precise magnetic field control in three-dimensional space. By adjusting the current intensity and phase of each axis coil, the rate of change of magnetic flux can be adjusted in real time to adapt to different scanning requirements. Multiple metal terminals are arranged from top to bottom across the first groove and respectively in multiple second grooves. These metal terminals are welded to the bottom of multiple metal sheets, which perfectly fits the magnetic core structure with the base, making the two tightly connected and the structure more stable. During long-term use, it can provide stable support for the coil body, thus solving the problems mentioned in the above-mentioned technical background.
