Abstract: A high-leakage planar magnetic component such as an inductor, having a winding structure in which flat winding turns are oriented transverse to the plane of the winding structure, exhibits significantly lower winding losses than components having a stacked arrangement of flat winding turns parallel to the plane of the winding structure. A dense winding structure having such a transverse orientation can readily be made by forming a flat conductor into a coil using conventional wire winding techniques.

Abstract: Electrical connector for telephone wiring interface comprises dielectric base having four stamped and formed first terminals thereon which receive screws for terminating wires and have upright first mating members aligned with apertures in a dielectric cover latched to base. Each first terminal is formed with a stanchion normal to the base and a spring contact which are received in a dielectric jack mounted to the base to provide testing by inserting a plug inserted through an aperture in the cover. A plug member has four stamped and formed second terminals fixed thereon which receive screws for terminating wires and upright second mating members arranged to mate with first mating members in apertures. Plug member has a leg flanking each second mating member, the legs being profiled to fit closely in apertures to align respective mating members for mating, which retains plug member against cover. Base and cover accommodate lightning arrestor and circuitry as desired.
