Abstract

A magnetic coupling having two or more elements for providing a conduit. The coupling provides high retention of conduit elements with minimum size magnetic components, while also providing for intentional detachment of the magnetically coupled elements. The coupling is configured to facilitate detachment with applied loads that are substantially less than operational retention force (i.e., breakaway force) of the magnetically coupled elements. The magnetic coupling device includes a connecting male element and a female element and at least one internal conduit integral to at least one of the connecting male and female elements. Magnetic attraction is accomplished via a magnetic circuit where the magnetic circuit includes ferromagnetic material and at least one permanent magnet.

Dependent claims

A magnetic coupling device for providing removable-attachment of a conduit comprising;

a male element and a female element and at least one internal conduit within;
said male element comprising an anterior end and a posterior end;
said anterior end of said male element comprising a first magnetic armature;
said first magnetic armature comprising at least one magnetic material forming a substantially closed ring around the periphery of said at least one conduit;
said female element comprising an anterior end and a posterior end;
said anterior end comprising of said female element comprising a second magnetic armature near said anterior end;
said second magnetic armature comprising at least one magnetic material forming a substantially closed ring around the periphery of said at least one conduit;
said anterior ends of said male element and said female element being adapted for interfitting in a plug and socket type arrangement whereas said first magnetic armature is magnetically attracted to said second magnetic armature when said anterior end of said male element is fitted within said anterior end of said female element;
said first magnetic armature and said second magnetic armature adapted to attract together to form a magnetic circuit;
said magnetic circuit comprising ferromagnetic material and at least one permanent magnet.
