Latest Patents

Taniguchi's latest patents include a plug connector and adapter with a thermal protection circuit designed to discontinue current supply when overheating occurs. This invention provides a plug connector that can sensitively cut off the current supply in the event of abnormal heating in the fitting portion with a counter connector. The plug connector consists of contacts, a body that holds the contacts, a metal shell that covers the body, and a printed circuit board on which the contacts are solder-connected. The body features a fitting portion with a counter connector, and the board is equipped with a thermal protection circuit. This circuit includes a temperature switch that detects temperature and an FET that is disposed in the power supply wiring of the board. When the detected temperature exceeds a predetermined threshold, the power supply wiring is cut off by the FET. Additionally, the board has a heat conduction pattern that conducts heat from the metal shell to the temperature switch.

Another significant patent by Taniguchi is a connector that includes a thermal protection circuit capable of detecting abnormal heating to cut off the power supply. This connector features a cover portion, a plug portion, and a printed circuit board. The thermal protection circuit comprises an FET inserted in the power supply line of the printed circuit board and a temperature switch IC that detects temperature. When the detected temperature exceeds a predetermined level, it outputs an abnormal heating signal that causes the FET to cut off the power supply line. The connector also includes a metal bonding member that thermally couples the metal shell to the temperature switch IC, ensuring high sensitivity in cutting off power supply in response to abnormal heating.
