  • Higher frequency switch mode transformer
    Patent number: 5982263
    Abstract: Transformer (1) for switched-mode power supply, equipped with a former (6) having chambers (9), each chamber (9) containing windings (15, 16), each winding (15, 16) having an outer side surface (18) generated by a straight line moving parallel to an axis (AA') of the former, and characterized in that the generatrices of all the outermost surfaces (18) of the windings (15, 16) contained in each of the chambers (9) are identically the same for all the outermost surfaces (18) of the windings (15, 16) of each of the chambers, these generatrices thus forming a unique cylindrical surface parallel to the axis (AA') of the former (6).

  • Device for fitting and gripping of a flexible cable in a cylindrical orifice and high-voltage transformer euipped with this device
    Patent number: 5773758
    Abstract: The disclosure is a device for mechanical assembly of a flexible cable in a cylindrical orifice, including a cable grip member slotted axially and carrying at least two helical threads on the outside and protuberances on the inside. The cylindrical orifice has a thread that engages the threads of the cable grip member. To fit the cable, the cable grip member is pushed axially into the cylindrical orifice, then the flexible cable is inserted axially in the cable grip member. Removal of the cable is achieved by unscrewing the cable grip member from the cylindrical orifice. The protuberances and the compression effect produced by the helical threads pulling on the thread in the cylindrical orifice when axial tension is applied to the cable assure efficient gripping of the cable.
