摘要： A magnetic fastener comprising a permanent magnet member having first and second sides of opposite polarity, a first magnetic pole plate attached at the first side of the magnet member, a second magnetic pole plate removably attachable on the second side of the magnet member, the pole plates being magnetically attracted to the magnet member and to each other through the magnet member, the permanent magnet member being a dispersion of hard magnetic powder in a matrix of synthetic resin, and the first magnetic pole plate being integrally attached to the permanent magnet member by the permanent magnet member itself. The permanent magnet member may be comprised of a molded member made by casting wherein the first magnetic pole plate is at least partly incorporated in the molded magnetic member or may be embedded therein. A hole is provided through the permanent magnet member extending between the first and second sides, and projections on the first and second pole plates extend into the hole so that the projections are magnetically attracted to each other and to the corresponding pole plate. The permanent magnet member being comprised of hard magnetic powder bound together by a synthetic resin and the first pole plate being incorporated as a part of the permanent magnet itself obviates the necessity for a protective covering or casing over the permanent magnet member and a reduction in the magnetic reluctance between the permanent magnet member and the first and second pole plates.

摘要： A magnetic fastener has a fastening element and an attracted element. The fastening element has a permanent magnet with a hole substantially parallel to the direction of the magnetic poles and a ferromagnetic plate on one side of the magnet facing the hole. The attracted element also has a ferromagnetic plate adapted for connecting to the open side side of the magnet facing the hole. Either one or both of the first and second plate can have a ferromagnetic rod that extends into the magnet hole. If only one rod is formed, the length of it extends substantially the depth of the magnet so that when the attracted element is connected to the fastening element, the end of the rod is near or contacting the opposing ferromagnetic plate through the magnet hole. If a rod is formed on each plate, the combined length of the rods is such that the ends thereof are near or touching within the magnet hole when the attracted element is fully engaged to the fastening element. In any event, at least one of the rods has a blind hole extending from the respective plate toward the respective end of the rod. The blind hole cross-sectional area is at least 2.2% but no more than 88.9% that of the rod.
