Abstract: An anti-theft lock for a portable electronic device has a mounting shaft, two buckling units, a split-abutting unit, and a controlling unit. The two buckling units are moveably mounted around the mounting shaft. The split-abutting unit is moveable and has an engaging end and a split-abutting end. The split-abutting end selectively abuts the two buckling units via the movement of the split-abutting unit. The controlling unit has an annular curved surface. The annular curved surface slidably abuts the engaging end of the split-abutting unit. During the rotation of the controlling unit, the annular curved surface is capable of pushing the split-abutting unit to make the split-abutting end abut the two buckling units with inclined surfaces to move the two buckling units away from each other. The larger a distance the split-abutting unit moves, the larger a distance the two buckling units move away from each other.

Abstract: A mechanical latching device of an electromagnetic contactor eliminates a need to adjust a gap between portions mechanically preventing returning of a latch support. A latch support includes a protrusion protruding laterally and formed with a latch surface facing a released side. A rotating member has one end side rotatably supported and the other end side biased toward the protrusion. When the latch support is on the released side, an outer peripheral surface of the other end side contacts with a tip of the protrusion to allow the latch support to be displaced to a closed side. When the latch support is on the closed side, the other end side rotates according to a position of the latch support in a displacement direction, and a tip surface faces the latch surface to mechanically prevent the latch support from returning to the released side at plural positions along the displacement direction.
