Abstract
Disclosed are interposer electrical connector embodiments including magnetic components used to facilitate interconnection of peripheral devices to standard input/output, or “I/O”, connectors (such as USB connectors) of devices such as mobile communications products (e.g. smart phones, tablets, and personal computers). The interposer connector embodiments disclosed include those in which a plurality of discrete permanent magnets are arranged with magnetic poles aligned in the same orientation perpendicular to and on one side of the electrical interface. Other embodiments include a plurality of bar permanent magnets located on opposite sides of the interface with all poles of the same type directed at the interface, but each one opposing a ferromagnetic element. These arrangements provide self-aligning capabilities useful for electrical connections that have restrictions on visibility or connection approach geometries. Other embodiments have a single magnet per mated connector pair and magnetic pole pieces and/or actuators to concentrate magnetic flux providing the magnetic attractive force for a plurality of electrical connections.
