| A signal transmission arrangement includes input terminals for receiving an input signal and output terminals for providing an output signal. A first transformer has a primary winding and a secondary winding, the primary winding being coupled to the input terminals. A second transformer has a primary winding and a secondary winding, the primary winding being coupled to the secondary winding of the first transformer, and the secondary winding being coupled to the output terminals. | ||||||

| Methods, systems, and devices are described for integrating multiple transformers on a shared core, while avoiding interference between the transformers and other potentially undesirable effects of the integration. In one embodiment, multiple transformers are wound on a shared core. Each transformer is wound on the core, so that its primary and secondary windings are magnetically coupled to each other through the core without being coupled to the windings of other transformers sharing the core. The multiple integrated transformers may then be provided in a circuit arrangement by placing only a single core element in the arrangement. | ||||||

| A transformer comprises a rectangular insulative housing, a plurality of inductive coils received in the insulative housing, and a plurality of soldering tails. The insulative housing includes a bottom wall and four sidewalls, and forms a plurality of partitions therein for receiving the inductive coils. Each inductive coil has a first wire and a second wire. The soldering tails are provided at two opposing sidewalls of the insulative housing. Each soldering tail has a soldering end at exterior of the insulative housing for electrically connecting with a PCB of a communication connector, and a wiring end at interior of the insulative housing for connecting with the first wire and the second wire of the inductive coils. The transformer is modularly produced, and is tested before it is assembled to a communication connector. Thus the manufacture process is flexible and the communication connector provides stable signal transmission. | ||||||
| 85 | Flat matrix transformer | US825230 | 1986-02-04 | US4665357A | 1987-05-12 | Edward Herbert |
| A flat matrix transformer or inductor is made of a plurality of interdependant magnetic circuits, arranged in a matrix, between and among which electrical conductors are interwired, the whole cooperating to behave as a transformer or inductor. The flat matrix transformer or inductor has several advantageous features, among them compact size, good heat dissipation and high current capability. A flat matrix transformer or inductor can be very flat indeed, nearly planar, and can be built using printed circuit board techniques. A flat matrix transformer can insure current sharing between parallel power sources, and/or between parallel loads. The flat matrix transformer can be configured to have a variable equivalent turns ratio. | ||||||

| In a transformer for use in a receiver set, a non-magnetic material arranged in part of a closed magnetic path established by a magnetic core is made of a plastic material such as paper mash or silicon putty. The non-magnetic material is pressurized and deformed so as to set the inductance of a coil mounted on the magnetic core to a predetermined value. | ||||||
| 87 | Wire coil assembly for an electrical circuit | US54094 | 1979-07-02 | US4229722A | 1980-10-21 | Perry C. Olsen |
| A wire coil assembly including a form for supporting a wire wound thereon, a base for the wire form, and terminals attached to the base and to which the ends of the wire are respectively connected. The base includes a number of exposed grooves through which the wire ends are routed from the wire form to the terminals. The grooves are configured to contain the wire ends, thereby eliminating exposed wire ends which would otherwise be susceptible of stress breakage when the coil assembly is handled. | ||||||
| 88 | Transformer | US3717833D | 1971-08-23 | US3717833A | 1973-02-20 | AGAWA S; KUBOTA Y |
| 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, nonmagnetic outer case prevent electric field coupling and suppress leakage at the center tap.
