Abstract

A device may comprise a housing having a straight rounded edge. A self-aligning connector at the straight rounded edge may comprise a cylindrical magnet oriented with its axis substantially parallel to the straight rounded edge. The cylindrical magnet is for magnetically engaging a magnet of another connector so as to align and connect the self-aligning connector with the other connector. The self-aligning connector may comprise mounting structure configured to mount the cylindrical magnet at the straight rounded edge of the housing with the axis of the cylindrical magnet being substantially parallel to the straight rounded edge of the housing. The device may include two such self-aligning connectors, spaced apart from one another, along a single straight rounded edge of the device housing.
