AI Technical Summary
The screw-fixing method of traditional sewing machine control panels results in low disassembly and assembly efficiency and the risk of component damage. The plug-in electrical connection structure is not reliable under frequent operation. The spatial separation design of the fixing module and the connecting module limits the optimization of the overall structure, affecting maintenance difficulties, shortening service life and product aesthetics.
It adopts an integrated structure of magnetic fixing unit and electrical connection unit. It achieves adsorption and fixation by setting corresponding magnet groups on the operation panel and the housing, and connects the conductive circuit through elastic contact parts, eliminating the defects of screw fastening and plug-in interface, and realizing convenient disassembly and assembly and permanent electrical connection.
It enables screwless assembly and disassembly and plug-and-play connections, improving assembly and disassembly efficiency, extending component life, enhancing the overall appearance and dustproof performance of the product, and maintaining the stability and reliability of electrical connections.
