Rudolf Widemann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A coil form or body for coils is disclosed particularly for use in printed circuits. The coil form has a flange provided with insertable perforations in order to accommodate one-piece soldering lugs having soldering lug legs aligned at a right angle relative to one another in order to solder the coil wires and particularly for soldering into the printed circuit. The soldering lugs are equipped with at least one clamping element which abuts against the surface of the coil member flange when the soldering lug is pushed in and secures the coil form from shifting. The perforations are designed at a right angle and at least one latch is arranged on at least one soldering lug leg. This latch abuts against the exterior side of the flange when the soldering lug is inserted into the perforation.
Abstract: An electronic coil assembly having a coil body with attached soldering elements having projecting tangs extending at right angles from one another forming, respectively, pins for attachment of the coil onto printed circuit boards and soldering lugs for attachment of the ends of the coil wire, the elements being formed with integral spring means and being snapped into place in openings through flanges of the coil body.
