Title (EN) ELECTROMAGNETIC RELAY
(FR) RELAIS ÉLECTROMAGNÉTIQUE
(JA) 電磁継電器
Abstract:
(EN) Provided is an electromagnetic relay having improved cut-off capacity and which is capable of stably cutting off an arc. The electromagnetic relay (1) is provided with a fixed contact holder (12), a movable contact holder (14), an electromagnet device (A10), and magnets (17, 18). The fixed contact holder (12) extends in a prescribed direction, and is provided with a fixed contact (11). The movable contact holder (14) extends in a prescribed direction, and is provided with a movable contact (13). The magnets (17,18) are arranged in a direction orthogonal to the opening/closing directions of the fixed contact (11) and the movable contact (13). An extension space (E1) in which a generated arc is extended between the fixed contact (11) and the movable contact (13) is provided in front of the tip ends of the fixed contact holder (12) and the movable contact holder (14) in a prescribed direction. Furthermore, the extension space (E1) is provided respectively facing a surface (12b) of the fixed contact holder (12), and a surface (14b) of the movable contact holder (14).
(FR) L'invention concerne un relais électromagnétique ayant une capacité de coupure améliorée et qui est capable de couper de manière stable un arc. Le relais électromagnétique (1) est pourvu d'un support de contact fixe (12), d'un support de contact mobile (14), d'un dispositif électromagnétique (A10) et d'aimants (17, 18). Le support de contact fixe (12) s'étend dans une direction prescrite, et est pourvu d'un contact fixe (11). Le support de contact mobile (14) s'étend dans une direction prescrite, et est pourvu d'un contact mobile (13). Les aimants (17, 18) sont agencés dans une direction orthogonale aux directions d'ouverture/fermeture du contact fixe (11) et du contact mobile (13). Un espace d'extension (E1) dans lequel un arc généré est étendu entre le contact fixe (11) et le contact mobile (13) est disposé devant les extrémités de pointe du support de contact fixe (12) et du support de contact mobile (14) dans une direction prescrite. En outre, l'espace d'extension (E1) est disposé respectivement en face d'une surface (12b) du support de contact fixe (12), et d'une surface (14b) du support de contact mobile (14).
(JA) アークを安定して遮断することができ、遮断能力を向上した電磁継電器を提供する。電磁継電器(1)は、固定接点保持体(12)と、可動接点保持体(14)と、電磁石装置(A10)と、磁石(17,18)とを備える。固定接点保持体(12)は、所定の方向に延在し、固定接点(11)を設けている。可動接点保持体(14)は、所定の方向に延在し、可動接点(13)を設けている。磁石(17,18)は、固定接点(11)と可動接点(13)との開閉方向に直交する方向に配置されている。固定接点(11)と可動接点(13)との間で生じるアークが引き伸ばされる伸張空間(E1)が、所定の方向における固定接点保持体(12)と可動接点保持体(14)の先端の先方に設けられている。さらに、伸張空間(E1)は、固定接点保持体(12)の面(12b)に、及び可動接点保持体(14)の面(14b)に、それぞれ面して設けられている。
