Title (EN) CHIP-TYPE FUSE
(FR) FUSIBLE DE TYPE PUCE
(JA) チップ型ヒューズ
Abstract:
(EN) The present invention provides a chip-type fuse including: a main body part comprising an insulating material; a fuse conductor disposed in the interior of the main body part and having two end sections exposed from the main body part; and a pair of external electrodes respectively covering two edge sections of the main body part and respectively connected to the two end sections of the fuse conductor. There is a hollow section in the interior of the main body part, and the fuse conductor has a fusing section formed along a wall surface of the hollow section.
(FR) La présente invention concerne un fusible de type puce comprenant : une partie de corps principal comprenant un matériau isolant ; un conducteur de fusible disposé à l'intérieur de la partie de corps principal et ayant deux sections d'extrémité exposées à partir de la partie de corps principal ; et une paire d'électrodes externes recouvrant respectivement deux sections de bord de la partie de corps principal et respectivement connectées aux deux sections d'extrémité du conducteur de fusible. Il y a une section creuse à l'intérieur de la partie de corps principal, et le conducteur de fusible a une section de fusion formée le long d'une surface de paroi de la section creuse.
(JA) 本発明は、絶縁性材料から成る本体部と、本体部の内部に配置され、かつ本体部から露出した両端部を有するヒューズ導体と、本体部の両端部を各々被覆し、かつヒューズ導体の両端部に各々接続された一対の外部電極とを含むチップ型ヒューズであって、本体部の内部に空洞部が存在し、ヒューズ導体が、空洞部の壁面に沿って形成されている溶断部を有する、チップ型ヒューズを提供する。
