Abstract
Official abstract text for this publication.
This protective element includes a fusible conductor (1a), three or more electrodes (2a), (2b), (2c) electrically connected to each other via the fusible conductor (1a), and a heating element configured to heat and fuse the fusible conductor (1a).
First claim
Opening claim text (preview).
What is claimed is: 1. A protective element comprising: a fusible conductor; three or more electrodes electrically connected to each other via the fusible conductor; and a heating element configured to heat and fuse the fusible conductor, wherein two or more electrodes among the three or more electrodes are electrically connected to each other via a single fusible conductor, wherein the fusible conductor comprises the single fusible conductor, wherein the heating element is electrically insulated from the fusible conductor, wherein the three or more electrodes that power having different phases in polyphase alternating current are supplied, and wherein the three or more electrodes do not overlap in plan view. 2. The protective element according to claim 1 , wherein the fusible conductor and at least part of the heating element overlap each other in a plan view. 3. The protective element according to claim 1 , which is configured to supply power to the heating element when an abnormality in power supplied to some or all of the three or more electrodes is detected. 4. A protective element comprising: a fusible conductor; three or more electrodes electrically connected to each other via the fusible conductor; and a heating element configured to heat and fuse the fusible conductor, wherein two or more electrodes among the three or more electrodes are electrically connected to each other via a plurality of fusible conductors that are electrically connected to each other via a connection wiring, wherein the fusible conductor comprises the plurality of fusible conductors, wherein the three or more electrodes that power having different phases in polyphase alternating current are supplied, and wherein the three or more electrodes do not overlap in plan view. 5. The protective element according to claim 4 , wherein the connection wiring and at least part of the heating element overlap each other in a plan view. 6. The protective element according to claim 4 , wherein the heating element is electrically insulated from the fusible conductor. 7. The protective element according to claim 4 , wherein the heating element is electrically connected to the fusible conductor. 8. A protective circuit comprising: a fusible conductor; three or more electrodes electrically connected to each other via the fusible conductor; and a heating element configured to heat and fuse the fusible conductor, wherein two or more electrodes among the three or more electrodes are electrically connected to each other via a single fusible conductor, wherein the fusible conductor comprises the single fusible conductor, wherein the heating element is electrically insulated from the fusible conductor, and wherein the three or more electrodes that power having different phases in polyphase alternating current are supplied. 9. The protective circuit according to claim 8 , wherein the fusible conductor and at least part of the heating element overlap each other in a plan view. 10. The protective circuit according to claim 8 , which is configured to supply power to the heating element when an abnormality in power supplied to some or all of the three or more electrodes is detected. 11. A protective circuit comprising: a fusible conductor; three or more electrodes electrically connected to each other via the fusible conductor; and a heating element configured to heat and fuse the fusible conductor, wherein two or more electrodes among the three or more electrodes are electrically connected to each other via a plurality of fusible conductors that are electrically connected to each other via a connection wiring, wherein each of the plurality of fusible conductors is the fusible conductor, and wherein the three or more electrodes that power having different phases in polyphase alternating current are supplied. 12. The protective circuit according to claim 11 , wherein the connection wiring and at least part of the heating element overlap each other in a plan view. 13. The protective circuit according to claim 11 , wherein the heating element is electrically insulated from the fusible conductor. 14. The protective circuit according to claim 11 , wherein the heating element is electrically connected to the fusible conductor.
