Abstract:
(EN) Provided are a contact device, an electromagnetic relay and electrical equipment capable of suppressing deterioration between a fixed contact and a movable contact by facilitating movement of a generated arc. The contact device (A1) is provided with a movable contactor (10), a pair of movable contacts (11) aligned in one direction, a pair of fixing terminals (12, 13), and a pair of fixed contacts (14, 15). At least one fixing terminal of the pair of fixing terminals (12, 13) has a contact holding part (12a, 13a). The contact holding part (12a, 13a) has a first fixed extension part (120a, 130a), and a second fixed extension part (120b, 130b). Regarding a current component flowing into a fixed contact in one direction or a current component flowing out from a fixed contact in one direction, the amount of current of the current component of the first fixed extension part (120a, 130a) side is greater than that of the current component of the second fixed extension part (120b, 130b) side.
(FR) L'invention concerne un dispositif de contact, un relais électromagnétique et un équipement électrique susceptibles de supprimer la détérioration entre un contact fixe et un contact mobile en facilitant le mouvement d'un arc généré. Le dispositif de contact (A1) est pourvu d'un contacteur mobile (10), d'une paire de contacts mobiles (11) alignés dans une direction, d'une paire de bornes de fixation (12, 13) et d'une paire de contacts fixes (14, 15). Au moins une borne de fixation de la paire de bornes de fixation (12, 13) comporte une partie de maintien de contact (12a, 13a). La partie de maintien de contact (12a, 13a) a une première partie d'extension fixe (120a, 130a) et une seconde partie d'extension fixe (120b, 130b). Concernant une composante de courant circulant dans un contact fixe dans une direction ou une composante de courant circulant hors d'un contact fixe dans une direction, la quantité de courant de la composante de courant du côté première partie d'extension fixe (120a, 130a) est supérieure à celle de la composante de courant du côté seconde partie d'extension fixe (120b, 130b).
(JA) 発生したアークの移動を促進させることにより固定接点と可動接点との劣化を抑制することができる接点装置、電磁継電器及び電気機器を提供する。接点装置(A1)は、可動接触子(10)と、一方向に並ぶ一対の可動接点(11)と、一対の固定端子(12,13)と、一対の固定接点(14,15)とを備える。一対の固定端子(12,13)の少なくとも一方の固定端子は、接点保持部(12a,13a)を有する。接点保持部(12a,13a)は、第1固定延長部(120a,130a)と、第2固定延長部(120b,130b)とを有する。一方向において固定接点に流入する電流成分又は一方向において固定接点から流出する電流成分について、第1固定延長部(120a,130a)側の電流成分の電流量の方が、第2固定延長部側(120b,130b)の電流成分より大きい。
