Abstract: An improved low cost and highly consistent inductive apparatus. In one embodiment, the low cost and highly consistent inductive apparatus addresses concerns with so called conductive anodic filament (CAF) that occurs within these laminate structures. These conditions include high humidity, high bias voltage (i.e. a large voltage differential), high-moisture content, surface and resin ionic impurities, glass to resin bond weakness and exposure to high assembly temperatures that can occur, for example, during lead free solder bonding application. In a variant, mixed mode coupling techniques are utilized in order to extend the underlying operating bandwidth of the substrate inductive device. Methods of manufacturing and using the aforementioned substrate inductive devices are also disclosed.

Abstract: A power supplying module includes a printed circuit board (PCB), a transformer, a circuit pattern, and an output terminal. The PCB includes a first socket connector protruded from a side toward a second direction. The side extends along a first direction different from the second direction. At least one corner portion of the first socket connector includes a chamfered edge connecting first and second edges respectively extending in the first and second directions. The transformer is formed on the PCB. The circuit pattern is formed on the PCB and connected to the transformer. The output terminal is formed at the first socket connector and connected to the circuit pattern.

Abstract: A network connector includes a housing, an integral printed circuit board in the housing, and a locking mechanism in the housing. The locking mechanism is operative for removably securing an assembled transformer component in operative relation to the integral printed circuit board. Contacts are provided on the integral printed circuit board for contacting contacts of the assembled transformer component when the assembled transformer component is secured in operative relation to the integral printed circuit board. Connector pins extend between a connector in the housing and the integral printed circuit board. Mounting pins extend through the housing from the integral printed circuit board to a position outside the housing for connection to an external printed circuit board. A number of the connectors can be arranged vertically, side-by-side, or both vertically and side-by-side.

Abstract: An electrical connector (1) has a base portion (22), a number of terminals (3) mounted to the base portion, a first circuit board (42) assembled to the base portion, a substrate paralleled with the base portion and a number of pins (212) mounted on the substrate and a second circuit board (41) electrically engaging with the number of pins. The first and the second circuit boards together defines a receiving space (6). The electrical connector further has a number of electrical elements (5) received in the receiving space and together electrically connecting with the first circuit board and the second circuit board.

Abstract: An electronic device includes an electronic circuit section, a case, and a connector housing. The electronic circuit section includes a connector terminal. The case seals the electronic circuit section in such a manner that the connector terminal protrudes to an outside of the case. The connector housing is integrated with the case and has an approximately cylindrical shape to surround an outer circumference of the connector terminal. The case and the connector housing are made of resin with a molding tool by filling resin into a case cavity and a connector-housing cavity of the molding tool in a state where the electronic circuit section is held by a holding portion of the molding tool.

Abstract: An electro-acoustic transducer, for example a microphone, with a holder is provided with a block-shaped holder having on the front face a housing chamber housing a microphone main body with its acoustic holes situated on the external face, the microphone main body housed in the housing chamber, a plurality of connection electrodes connected to a plurality of terminal electrodes formed on the microphone main body, respectively, and a plurality of mounting electrodes exposed at each of a front face, a back face and a rear end face in correspondence with the plurality of connection electrodes.

Abstract: A low profile microphone connector includes a dielectric housing and electrical terminals located in the housing. The housing has a generally cylindrical wall, a generally cylindrical microphone insertion cavity defined by the cylindrical wall, a supporting base formed at a lower portion of the cylindrical wall, and a plurality of ribs formed at an upper portion of the cylindrical wall. A PCB has a generally circular hole and a plurality of positioning slots defined along the periphery of the circular hole. In assembly, the cylindrical wall sinks into the circular hole of the PCB, the supporting base abuts against a bottom face of the PCB, and the ribs engage with the positioning slots to position the connector on the PCB. So the connector has a low profile over the PCB and reliably retained on the PCB.
