Abstract
Official abstract text for this publication.
A temperature protection device of an electronic device according to the present technology is inserted and connected in a current-carrying circuit between a power supply unit and an electronic device main body in which a temperature detecting element is installed, and includes a first switch inserted and connected in series in the current-carrying circuit from the power supply unit to the electronic device main body, a cutoff unit for controlling on/off of the first switch, a current fusing element of which one end is connected to the current-carrying circuit to the electronic device main body, a second switch connected to the other end of the current fusing element, and a controller for controlling on/off of the second switch based on a temperature detection signal from the temperature detecting element.
First claim
Opening claim text (preview).
What is claimed is: 1. A temperature protection device of an electronic device, the temperature protection device to be inserted and connected in a current-carrying circuit between a power supply unit of the electronic device and an electronic device main body in which a temperature detecting element is installed, the temperature protection device comprising: a first switch inserted and connected in series in the current-carrying circuit from the power supply unit to the electronic device main body; a cutoff unit for controlling on/off of the first switch; a current fusing element of which one end is connected to the current-carrying circuit to the electronic device main body and to the first switch; a second switch connected to an other end of the current fusing element; and a controller for controlling on/off of the second switch based on a temperature detection signal from the temperature detecting element of the electronic device main body, wherein when the temperature detection signal shows an abnormal condition, the controller turns on the second switch for supplying electric current to the current fusing element to cause a blowout; and the cutoff unit turns off the first switch for cutting off the current-carrying circuit in response to the blowout of the current fusing element. 2. The temperature protection device of the electronic device according to claim 1 , wherein the second switch is a normally-off switch. 3. The temperature protection device of the electronic device according to claim 1 , wherein the current fusing element has a normally-off third switch connected in parallel with the current fusing element; and the third switch is turned on by a user after the current fusing element blows out.
