A connector wherein the connector has: a cover portion into which one end of a cable is configured to be inserted, and which is made of an insulating synthetic resin; a plug portion which is supported in a state where the plug portion is projected from a tip end of the cover portion , which is to be inserted into a mating connector , and which includes: an insulator ; a plurality of contact terminals that are supported by the insulator ; and a metal shell which covers an outer circumference side of the insulator ; and a printed circuit board which is placed in the cover portion , and on which a thermal protection circuit is mounted, the thermal protection circuit includes: an FET which is inserted in a power supply line of the printed circuit board ; and a temperature switch IC which detects a temperature, and which, when the detected temperature exceeds a predetermined temperature, outputs an abnormal heating signal for causing the FET to cut off the power supply line, and the connector further includes a metal bonding member which thermally couples the metal shell to the temperature switch IC , characterised in that the metal bonding member is configured by a metal plate member which is formed separately from the metal shell , which is integrated with the metal shell , and which extends from the metal shell to the temperature switch IC , and wherein the metal bonding member , otherthan a front end portion is covered by a bag shaped insulator with high thermal conductivity, secured by single-sided adhesive tape. a cover portion into which one end of a cable is configured to be inserted, and which is made of an insulating synthetic resin; a plug portion which is supported in a state where the plug portion is projected from a tip end of the cover portion , which is to be inserted into a mating connector , and which includes: an insulator ; a plurality of contact terminals that are supported by the insulator ; and a metal shell which covers an outer circumference side of the insulator ; and a printed circuit board which is placed in the cover portion , and on which a thermal protection circuit is mounted, the thermal protection circuit includes: an FET which is inserted in a power supply line of the printed circuit board ; and a temperature switch IC which detects a temperature, and which, when the detected temperature exceeds a predetermined temperature, outputs an abnormal heating signal for causing the FET to cut off the power supply line, and the connector further includes a metal bonding member which thermally couples the metal shell to the temperature switch IC , characterised in that the metal bonding member is configured by a metal plate member which is formed separately from the metal shell , which is integrated with the metal shell , and which extends from the metal shell to the temperature switch IC , and wherein the metal bonding member , otherthan a front end portion is covered by a bag shaped insulator with high thermal conductivity, secured by single-sided adhesive tape. an FET which is inserted in a power supply line of the printed circuit board ; and a temperature switch IC which detects a temperature, and which, when the detected temperature exceeds a predetermined temperature, outputs an abnormal heating signal for causing the FET to cut off the power supply line, and the connector further includes a metal bonding member which thermally couples the metal shell to the temperature switch IC , characterised in that the metal bonding member is configured by a metal plate member which is formed separately from the metal shell , which is integrated with the metal shell , and which extends from the metal shell to the temperature switch IC , and wherein the metal bonding member , otherthan a front end portion is covered by a bag shaped insulator with high thermal conductivity, secured by single-sided adhesive tape. <EOS>
