Abstract

A magnetic connector apparatus may comprise one or more magnet housings, each of which may comprise one or more magnets positioned therein to rotate within the magnet housing(s). The apparatus may be configured using one or more safety features in order to prevent access and/or removal of the magnet(s). In some embodiments, the apparatus may further comprise an inner retainer piece coupled with the one or more magnet housings, a first outer housing piece coupled with the inner retainer piece, and a second outer housing piece coupled with the inner retainer piece. The first outer housing piece may be positioned on an opposite side of the connector apparatus from the second outer housing piece such that the inner retainer piece is positioned in between the first outer housing piece and the second outer housing piece. Novel methods for manufacturing a magnetic connector apparatus are also disclosed.
