  • Patent number: 4246562
    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.
