Description

Technical Field

[0001] This application relates to the field of magnet technology, and in particular to a neodymium iron boron magnet assembly. Background Technology

[0002] A magnet is a magnetic stone that can attract metals. The magnets we usually refer to are permanent magnets. Permanent magnets can be natural products or artificially manufactured. Among artificially manufactured magnets, neodymium iron boron (NdFeB) magnets are the most widely used. Currently, NdFeB magnets are widely used due to their strong magnetic properties, including in various electronic products and various magnetic connection structures.

[0003] The processing of neodymium iron boron magnets includes sintering and cutting. Large pieces of neodymium iron boron magnets need to be cut into sheets or strips before magnetization. Their structure is generally simple, and they are fixed by slots during installation.

[0004] The existing magnet structure also has some problems. For example, due to the uniform shape of neodymium iron boron magnets, it is impossible to determine their polarity and positive and negative sides during installation, making the installation process cumbersome. At the same time, the existing magnet connection uses a simple slot fixation, which can easily cause the magnet to loosen after a certain period of time, affecting the connection effect. Therefore, the inventor believes that a neodymium iron boron magnet assembly with stable connection and convenient installation and fixation should be designed. Utility Model Content
