Embodiment Construction

[0036] Embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

[0037] For the sake of brevity, the same reference numbers will be used for the same or equivalent elements of construction.

[0038] Such as figure 2 and image 3 As shown, the electromagnetic switching device according to the embodiment of the present invention may include: a housing 210; a first contact 220 coupled to the housing 210; a second contact 240 in contact with the first contact 220 and with the The first contact 220 is separated; and the actuator 120 is used to drive the second contact 240 so that the second contact 240 is in contact with and separated from the first contact 220 . Any one of the first contact 220 and the second contact 240 may include an elastic deformation part 242 elastically deformed when the first contact 220 and the second contact 240 are in contact.

[0039] The case 210 may include an accommodation space ther...

Abstract

An electromagnetic switching device includes: a housing (210); first contacts (220) coupled to the housing (210); a second contact (240) which is brought into contact with the first contacts (220) and separated from the first contacts (220); and an actuator (120) for driving the second contact (240) such that the second contact (240) is brought into contact with the first contacts (220) and separated from the first contacts (220), wherein any one of the first contacts (220) and the second contact (240) includes an elastic deformation portion (242) elastically deformed when the first contacts (220) and the second contact (240) are brought into contact. Vibration and noise generated when contacts are brought into contact can be suppressed.

Description

technical field [0001] The present invention relates to an electromagnetic switching device, and more particularly to an electromagnetic switching device capable of limiting vibration and noise generated when contacts come into contact. Background technique [0002] As known, an electromagnetic switching device is an electrical contact opening and closing device for supplying or breaking electric current, which may be used in various industrial facilities, machinery, vehicles, and the like. [0003] figure 1 is a cross-sectional view of a prior art electromagnetic switching device. [0004] Such as figure 1 As shown, the electromagnetic switching device 100 includes an arc extinguishing unit 110 and a driving unit 120 . [0005] The arc extinguishing unit 110 may include a fixed contact 111 and a movable contact 112 . [0006] The housing 114 may be disposed outside the fixed contacts 111 and the movable contacts 112 . [0007] The driving unit 120 may be configured as,...
