A transformer has an insulator interposed between respective primary and secondary coils wound on a coil bobbin which has an axial winding part and opposing radially extending flanges. The insulator is made from a continuous sheet of material which is corrugated to provide an insulating base having a width larger than the width of the winding part of the coil bobbin and from a continuous, plastic insulating sheet member having substantially the same width as the winding part. The corrugated insu...

A transformer with twelve cores, a first six arranged in parallel rows of three, a second six, in parallel rows of three at right angles to the first six and positioned between the first and second, and second and third cores of each row of the first six; four coil assemblies each comprising a primary winding and a secondary winding, each of the coil assemblies embracing legs of four cores, the primary and secondary coils being electrically connected in parallel to like coils in other coil assem...

A transformer having primary and secondary windings on a conductive non-magnetic bobbin. A pot-type core surrounds the bobbin and windings and has a central magnetic core extending axially into the bobbin and windings. Flanges on the bobbin separate the primary from the secondary, and the flanges and bobbin have a slot to limit induction current losses. The secondary is center-tapped, and the flanges and conductive, non-magnetic outer case prevent electric field coupling and suppress leakage at ...

A transformer comprising an insulating body between the relatively parallel coil formers, said body being formed by a rectangular plate having upright edges on either side, the edges located in the core frame being slipped into incised parts of the coil former flanges.

A transformer is to be electrically connected to a circuit board. The transformer has a bobbin, a copper sheet assembly and a coil assembly. The bobbin has two side plates and a winding core on which a primary winding, a secondary winding and a magnetic core assembly are mounted. The copper sheet assembly as the primary or the secondary winding has multiple copper sheets. Each copper sheet is an inverted U-shape with two legs, and is mounted on a groove defined on the winding core. Engaging stru...

A transformer includes an end, and electrical insulator bushings are attached to and extend away from the end of the transformer. Conductors extend from the electrical insulator bushings. A cover has openings and an attachment end affixed to the transformer. The cover shields the end of the transformer and the electrical insulator bushings preventing animals from alighting on the end of the transformer and the electrical insulator bushings. The conductors each extend through one of the openings ...

A transformer core assembly in a transformer comprises a coil having a primary winding and a secondary winding which are successively wound about a hollow coil bobbin, in division, with respect to a longitudinal direction of the hollow coil bobbin, and a pair of E-type cores in which central core sections of respective three core sections extending in parallel relation to each other are inserted respectively from both ends of the coil bobbin into a hollow section therewithin. The core sections o...

A rotary motion transformer particularly adapted to provide continuous rotary motion to a driven member in response to an intermittently rotated driving member is provided. The driven member and the driving member are oppositely poled magnetic permeable members disposed proximate to each other to provide a flux field therebetween. The driven rotary member is disposed in a viscous damping reservoir, the viscous damping reservoir effecting smooth and continuous rotation of the driven member.

A transformer comprises a core formed by laminations, each having a rectangular plate with two spaced windows for receiving a set of coils passing through the windows in turn; a pair of terminal supports made of dielectric material, the supports extending through the core laminations down to the bottom thereof and being terminated by L-shaped brackets for mounting on the surface of the circuit board, the brackets spanning the width of the transformer and carrying two arrays of pins extending fro...

A high voltage current transformer, and method of constructing same, including a primary winding having concentric leads, and a secondary winding on a magnetic core which is inductively linked with the primary winding. The magnetic core is a wound, two part core, with the two core parts being joined by stepped-lap joints. The secondary winding is a distributed winding having turns which are uniformly distributed about the complete magnetic circuit of the magnetic core. The conductor of the secon...
