Abstract:
A surface mountable coil is provided with a drum-shaped core including a body portion and raised portion each raised portion having a peripheral surface and an end surface, a winding wire wound around the body portion, an encapsulating member, base electrodes, and terminal electrodes. The encapsulating member exposes some portions of the base electrodes on the peripheral surfaces and substantially the whole base electrodes on the end surfaces. By exposing the portions of the base electrodes on the peripheral surfaces and whole base electrodes on the end surfaces, the contact strength between the base electrodes and the terminal electrodes can be substantially increased.
Abstract:
A functional material—composite structural magnetic core is the magnetic core mainly consisting of magnetic material and having regular geometric form. It includes a box with a slot cavity and through hole. The inner magnetic core is installed inside the cavity of the box. It is characterized by: there are multiple inter-layers inside of the cavity of the slot. The inter-layers divide the slot cavity into the multiple continued ring slot and inside the ring slot many inner magnetic cores are installed respectively. The advantages are: wide application frequency band, large application temperature range, expanded electromagnetic compatibility. The continued stability and sudden change of the electromagnetic characteristics can meet requirements of the electronic technology. The sensing and sending of power transferred signal and control of noise wave etc. showed its composite excellent performance, corresponding and matching characteristics.
Abstract:
The present invention relates to a choke coil utilized in a variety of electronic products both for industrial use and consumer use, and aims to provide a choke coil that is thinner in size, accommodates a larger current, provides better efficiency in assembly and higher reliability. The choke coil of the present invention comprises a closing magnetic core having a center magnetic leg, an outer magnetic leg 36 and a common magnetic yoke. A coreless coil winds a plate-type wire around the center magnetic leg of the closing magnetic core to form itself, and is mounted to the closing magnetic core. At least one terminal coupled to an inner turn of the coreless coil out of terminals coupled to both ends of the plate-type wire of the coreless coil is led out from a notch provided on one side of the common magnetic yoke of the closing magnetic core.

A toroidal transformer enclosure is disclosed. The toroidal transformer enclosure includes a first housing member and a second housing member structured and arranged to receive the first housing member. The first housing member includes a first end, a first wall and a second wall. The first and second walls are connected to the first end, and the second wall surrounds the first wall. The second housing member includes a second end, a third wall and a fourth wall. The third and fourth walls are connected to the second end, and the fourth wall surrounds the third wall and defines a spacing therebetween. The first and second walls are disposed in the spacing between the third and fourth walls when the first housing member is received by the second housing member.
Abstract:
An ignition apparatus includes a central core extending along a main axis, and a primary winding disposed radially outwardly thereof. The ignition apparatus further includes a secondary winding. The primary winding has a greater axial length than the secondary winding, this additional axial length being implemented on the low-voltage axial end of the ignition apparatus, relative to the main axis. The extended primary winding provides an increased leakage inductance spike, which may be used by an ion sense system to (i) obtain increased bias voltages, and, (ii) increase the effective turns ratio, thereby reducing the amount of wire required for the secondary winding.
Abstract:
A housing for an electronic component has a set of walls for surrounding the component. The component is snap-fitted into the housing to retain it in the housing through snap-fit features in the housing and snap-fit features on the component. The housing can incorporate springs which, in use, bias the component into contact with the snap-fit features. If the component is a transformer, the springs can act on the transformer laminations to press the stack of laminations together while biasing the component into contact with the snap-fit features.
Abstract:
A method for forming a resin molding on a coil of a transformer is disclosed. The method comprises the steps of inserting a coil into an auxiliary spacing apparatus, inserting the auxiliary spacing apparatus into a mold, and forming a resin molding for the auxiliary spacing apparatus with the coil by putting a resin into the mold. According to the methods, the coil is not damaged and a resin molding is formed with a uniform thickness.
Abstract:
In an individual ignition type ignition coil for use in an internal combustion engine in which a center core 1, a secondary coil 3 wound on a secondary bobbin 2 and a secondary coil 5 wound on a primary bobbin 4 are installed concentrically from an inner side of a coil case 6 in order. Among these interior constituting members, insulation resins 17 and 8 are filled up. Each of the primary bobbin 4 and the secondary bobbin 2 is made of a synthetic resin and at least a skin layer on an inner surface of the primary bobbin 4 and a skin layer on an outer surface of the secondary bobbin 2 are removed, and to the surfaces of the bobbins, the insulation resin 8 is adhered closely. By heightening a close adhesion strength (a bonding strength) of a bobbin and an insulation resin in an individual ignition type ignition coil, an anti-heat shock is improved and an insulation performance of the coil is attained.
