CONTACTOR AND CONTACTOR SYSTEM

摘要

A contactor and a contactor system. A contactor (100) comprises: a fixed contact (10); a movable contact (3) which can move in a direction which is close to or far away from the fixed contact; two movable contact arc striking slices (5) which are respectively located on two opposite sides of the movable contact in a first direction and are fixed and electrically connected to the movable contact; two fixed contact arc striking slices (11) which are respectively located on two opposite sides of the fixed contact in the first direction and are fixed and electrically connected to the fixed contact; and two arc-extinguishing chambers (2, 9) which are arranged on an extension line extending from the movable contact and respectively passing through the two movable contact arc striking slices. According to an embodiment, the two movable contact arc striking slices form an incomplete enclosure for the movable contact, and the incomplete enclosure has a gap in a direction which is approximately orthogonal to the first direction. According to another embodiment, a contactor comprises a contact support (12), the contact support is internally provided with a cavity, and a movable contact and a fixed contact are arranged in the cavity.
