摘要: A high voltage transformer for a video display apparatus includes a bobbin-wound tertiary winding (24). The bobbin (41) incorporates integral nonmetallic terminal posts (43) about which the winding segment wire (51) is wound and terminated. The winding segments (19, 26-30) are interconnected by electrical components (31-33, 45, 46, 52). The component leads (53) incorporate a solder coating (54) and are flattened to provide a large bonding area with the wire (51) on the terminal posts (43). The component lead (53) overlays the winding segment wire (51) and is joined thereto preferably by a fusion bonding process. The fusion bonding removes the wire insulation (60) and melts the component lead solder coating (54) to form a reflow solder joint.

摘要: A video apparatus includes a cathode ray tube (10) and a igh voltage transformer (11). The high voltage transformer 11) incorporates a high voltage winding (24) having a tap 27) which provides a focus voltage for the electron gun ssembly (12) of the cathode ray tube. The transformer (11) lso includes a supply winding (31) which provides power to le electron gun assembly drive circuit (13). The supply vinding (31) is wound so as to be closely coupled to the ortion of the high voltage winding not associated with the eneration of focus voltage, so that increasing beam current roduces nonuniform loading of the high voltage winding 24).

摘要: Bei einem Diodensplit-Zeilen-Transformator ist vorgesehen, daß zwischen dem Fokussierungs-Siebkondensator (K) und der Kathode der ersten Diode (D1) der Hochspannungswicklung (W) ein Widerstand (R) vorhanden ist. Der Widerstand (R) entkoppelt den Fokussierungs-Siebkondensator (K) von der Hochspannungswicklung (W), so daß diese besser abgestimmt werden kann.

摘要: Transformator für einen Fernsehempfänger, dessen Kern die Wicklung eines Schaltnetzteils und die Wicklung des Zeilentransformators trägt. Durch einen E-Kern (1,2) mit speziell bemessenen Luftspalten (6, 7) wird eine gute Entkopplung der beiden Wicklungen (8, 9) erreicht.

摘要: 57 A core gap spacing arrangement for a transformer (10) includes a length of twisted wire (31, 32). The twisted wire has a relatively low packing density and is therefore compressible over a large range by using relatively low compression forces, resulting in greater ability to accurately adjust the inductance of the transformer primary winding (12).

摘要: A high voltage transformer (21) such as for a video display apparatus incorporates a bobbin (10) on which a primary winding (201) is wound. Transformer auxiliary coils (202, 203, 204), preferably wound directly over the primary winding (201) with no intermediate layers of insulation other than an insulating coating on the wire, each comprise wire turns which are evenly distributed over the full traverse of the primary winding (201) to improve magnetic coupling and simplify tuning of the transformer (21).
