Title (EN) PROTECTION ELEMENT
(FR) ÉLÉMENT DE PROTECTION
(JA) 保護素子
Abstract:
(EN) In order to provide a protection element that can achieve both the improvement of a current rating and the provision of a rapid current shutoff during an abnormality, and also improve insulation reliability after the current shutoff, the present invention is provided with: an insulation substrate (10); first and second electrodes (11, 12) provided on the insulation substrate (10); a heating element (14) formed on the insulation substrate (10); a heating element extracting electrode (16) electrically connected to the heating element (14); a first fusible conductor (31) mounted from the first electrode (11) across to the heating element extracting electrode (16); and a second fusible conductor (32) mounted from the second electrode (12) across to the heating element extracting electrode (16).
(FR) Afin de réaliser un élément de protection qui peut atteindre aussi bien une amélioration d’un courant nominal que l’application d’une coupure rapide de courant pendant une anomalie, et également améliorer la fiabilité d’isolation après la coupure de courant, la présente invention comporte : un substrat d’isolation (10) ; de première et deuxième électrodes (11, 12) disposées sur le substrat d’isolation (10) ; un élément chauffant (14) formé sur le substrat d’isolation (10) ; une électrode d’extraction (16) d’élément chauffant connectée électriquement à l’élément chauffant (14) ; un premier conducteur fusible (31) monté depuis la première électrode (11) à travers l’électrode d’extraction (16) d’élément chauffant ; et un deuxième conducteur fusible (32) monté depuis la deuxième électrode (12) à travers l’électrode d’extraction (16) d’élément chauffant.
(JA) 電流定格の向上と異常時の迅速な電流遮断の両立を図り、かつ電流遮断後の絶縁信頼性を向上する保護素子を提供する。絶縁基板(10)と、絶縁基板(10)に設けられた第1、第2の電極(11、12)と、絶縁基板(10)に形成された発熱体(14)と、発熱体(14)と電気的に接続された発熱体引出電極(16)と、第1の電極(11)から発熱体引出電極(16)にわたって搭載された第1の可溶導体(31)と、第2の電極(12)から発熱体引出電極(16)にわたって搭載された第2の可溶導体(32)とを備える。
