An electrical connector, comprising:
- a connector body, including a cavity and defining a contact aperture that provides an opening to the cavity through a connector surface;
- an electrical contact situated in the cavity, the electrical contact comprising:
- a ball comprising magnetic material;
- and
- a retainer that includes a planar spiral spring portion and a ring portion, wherein:
- the retainer comprises an electrically-conductive material;
- the ring portion has a ring diameter that is smaller than a diameter of the magnetic ball and is arranged to circumferentially contact the magnetic ball;
- the planar spiral spring portion is arranged to cause the ring portion to press the magnetic ball into the cavity and away from the contact aperture in an absence of magnetic interaction between the magnetic ball and a second magnetic ball of a peer electrical contact;
- and
- during interaction between the magnetic ball and the second magnetic ball, the planar spiral spring portion is strained and the magnetic ball protrudes partially from the connector body while maintaining electrical contact with the second magnetic ball.
An electrical connection including two electrical connectors, each of which includes a connector body with a contact aperture, each connector body defining a cavity in which an electrical contact is situated, the electrical contact comprising a magnetic ball and a retainer comprising a current-conducting material;
- wherein the retainer in each electrical connector is made as a spring shaped planar spiral and having a ring portion;
- wherein the ring portion has an internal diameter that is smaller than a diameter of the magnetic ball;
- wherein the retainer is arranged to bias the magnetic ball inward into the cavity and away from the contact aperture in an absence of interaction between the magnetic balls of the two electrical connectors;
- and
- wherein in a presence of an interaction between the magnetic balls of the two electrical connectors, each spring portion is strained and the respective magnetic ball of each of the two connectors protrudes from its corresponding connector body while remaining in electrical contact with the other magnetic ball of the other electrical connector.
