Abstract:
1. A two-part electrical connector, comprising: a first part including a tongue portion having a base and a tongue extending longitudinally therefrom; a second part including a socket portion having a base and walls extending therefrom defining a socket for slidably receiving the tongue, the tongue portion and socket portion having locking means to permit releasable mutual engagement, said locking means including a locking member moveable between a first position in which the tongue is held in the socket and a second position in which the tongue is removable from the socket; a primary coupling element located in the tongue; and a secondary coupling element located in at least one of the socket walls, which elements provide a contact-less electromagnetic coupling when the tongue is engaged in the socket, wherein the primary and secondary coupling elements are primary and secondary inductors, respectively, and each includes a conductive coil wound around a ferromagnetic core, and the secondary conductive coil is located in the socket base and the secondary inductor core has two elongate arms extending into the socket walls so that when the tongue is engaged in the socket, the primary inductor is located between the two arms.
