Magnetic inductively-coupled connector
First Claim
1. An inductive connector comprisinga pair of mating metallic housing units within each of which is mounted a metallic support plate respectively having a plurality of closely spaced recesses arranged in the same pattern,a plurality of transformer couplings each made in two separable sections which are received in opposing recesses in said support plates,each two-section transformer coupling comprising a ferrite magnetic core composed of two substantially identical, one-piece, opposing cup-type core halves each including a center member about which one transformer winding is disposed and also an outer member, said core halves when assembled having a magnetic gap therebetween with the transformer windings and center members collinear and magnetically coupled and further substantially enclosed by said outer members.a protective coating over at least exposed areas of said core halves and transformer windings, andmeans for releasably clamping together said housing units with the two sections of each transformer coupling in alignment.

Abstract
An electrical connector for applications where reliability and safety are needed uses transformer couplings made in two separable sections. Upon clamping together the surrounding metal housing halves, each inductively coupled pair of transformer windings is enclosed by the associated cup-type ferrite magnetic core to minimize undesired interference and result in good magnetic coupling.
