The granted patent US12046434B2 describes an innovative arc path generation unit designed to enhance the functionality of direct current relays. Central to this invention is a magnetic frame that houses a space accommodating multiple fixed contacts and a movable contact. The unit incorporates a Halbach array, strategically positioned within the magnetic frame to create a magnetic field, alongside a separate magnet part. The design features a space part that is elongated in one direction, with the magnetic frame comprising four surfaces that enclose this space. The Halbach array consists of multiple blocks made from magnetic material, arranged side by side, and can be positioned adjacent to various surfaces of the magnetic frame. The configuration allows for multiple Halbach arrays and magnet parts to be arranged in a manner that optimizes magnetic interactions.

The claims further detail the specific arrangements and polarities of the Halbach arrays and magnet parts. For instance, the surfaces of the Halbach arrays facing each other are magnetized with the same polarity, while those of the magnet parts exhibit differing polarities. The patent also outlines various configurations of the Halbach arrays, including the arrangement of blocks within them, which can be biased toward specific surfaces of the magnetic frame. This intricate design aims to improve the efficiency and reliability of the arc path generation unit, making it a significant advancement in the field of direct current relay technology.
