Said method for manufacture of toroidal transformers has properties superior for automated mass production and comprises the steps of arranging a coil around the periphery of at least one first bobbin of elongated shape and of flexible material, providing at least one second bobbin, said second bobbin being essentially shaped as a circular segment and having at least one first inner cavity and at least one second inner cavity arranged around and along said at least one first inner cavity, feeding said at least one first bobbin, together with said coil, into said at least one second bobbin around said at least one first inner cavity, so that said coil is packed in said at least one second inner cavity, forming a component being essentially shaped as a circular segment, wherein at least one of said component ends defines an opening, joining at least two of said components together, so that a combined component is formed, wherein at least one of said combined component ends defines an opening, and feeding a ribbon of magnetic material through said opening, so that said ribbon is being wound a required amount of tightly packed winding turns inside said at least one first inner cavity until essentially the whole at least one inner cavity of said combined component is filled, said ribbon thereby forming a core .
Abstract:
An inductive device comprises a coil (10) having a winding (12) and extending along and spaced from an axis, and a pair of lead wires (18, 20) extending internally between the ends of the coil. The lead wires (18, 20) extend externally from one of said ends for connection to an electrical circuit, and form start (22) and finish posts (24) at the other of said ends. The respective ends of the winding (26, 28) are wound on and electrically connected to the posts (22, 24), for which purposes the posts extend axially away from the coil in spaced relationship.
Abstract:
A method for high speed spin winding a coil on a continuous lamination core. A two piece or hinged bobbin (26) having two flanges (30, 34) is placed around a leg of the transformer core (22) and snapped together. Both flanges include an outwardly facing surface which defines a concentric groove (46). One flange includes passages (54) for receiving printed circuit board terminating pins (58) which are installed prior to winding the coil. The other flange has a circumferential gear (30) located in its outwardly facing surface. The core with bobbin and terminating pins installed is placed into a spin winding fixture. A bobbin bearing (62) having a bearing surface including a circumferential ridge (74) is placed adjacent the outwardly facing surfaces of the two flanges (30, 34) such that the circumferential ridges (74) are partially received within the concentric grooves (46) of the outwardly facing surfaces of the two flanges (30, 34). A wire feeder terminates the leading end of the coil wire on one of the terminating pins (58). A drive gear engages the circumferential gear (30) on the flange and rotates the bobbin at high speed drawing wire from the wire feeder. The wire feeder moves back and forth between the two flanges to uniformly wind the coil wire on the bobbin. The wire feeder terminates the trailing end of the coil wire on the other terminating pin and then cuts the wire off. The terminating pins are pressed further into the flange until the desired length for printed circuit board connection extends outwardly from the opposite side of the flange.

Abstract:
A method provides a radial drop winding for an open wound transformer. A plurality of non-electrically conductive posts (10) are arranged to define an interior space. Each post is of generally L-shape having a main body (14) and a leg (16) extending from a bottom end of the main body. During an open winding process, conductive wire (54) is dropped to build up lengthwise along the posts to define at least one generally cylindrical winding segment (56, 58) supported by the legs of the posts.
