Magnetic latch |
摘要 |
A magnetic latch includes a first member having a protrusion and a second member engaging the protrusion to prevent the first member and the second member from sliding relatively to one another. The second member includes a first magnet to attract the first member and a first solid non-magnetic member located inside a cavity of the first magnet to enhance attraction between the first member and the second member. The second member can be provided with a backing plate to facilitate a magnetic flux path from the magnet to the magnet aperture. The second member can also include a second magnet to attract the first member and a second solid non-magnetic member located between the first magnet and the second magnet. A third solid non-magnetic member can be provided on the outer periphery of the magnets. This design provides a latch with stronger holding power.
