Embodiment Construction

[0071] according to Figure 1A to Figure 9BEmbodiments of the electromagnetic relay of the present invention will be described.

[0072] Such as figure 2 , image 3 As shown, the electromagnetic relay of the first embodiment has a base 10 , an electromagnet unit 30 , a movable contact unit 40 and a permanent magnet unit 50 .

[0073] Such as figure 2 As shown, the above-mentioned base 10 is a resin molded product viewed from above as a square shape, and two normally closed fixed contact terminals 21 and normally open fixed contact terminals 21 as a set are vertically provided at adjacent corners of the upper surface thereof. twenty two. A normally closed fixed contact 23 and a normally open fixed contact 24 are respectively riveted and fixed on the normally closed fixed contact terminal 21 and the normally open fixed contact terminal 22 . In addition, on the upper surface of the above-mentioned base 10, a horizontal groove portion 13 is provided between the above-mentio...

Abstract

An electromagnetic relay has a base (10); a first stationary contact terminal (22) having a first stationary contact (24) and fixed on the base (10); a first movable contact plate (42) having a first movable contact (43) mounted on the first movable contact plate (42); an electromagnet unit (30) mounted on the base (10) for moving the first movable contact plate (42) to make or break a contact with between the first stationary contact (24) and the first movable contact (43); and a permanent magnet (53) mounted on the base (10) so as to extend an arcing (61) to be generated between the first stationary contact (24) and the first movable contact (43) toward the base (10).

Description

technical field [0001] The present invention relates to an electromagnetic relay, and more particularly to an electromagnetic relay capable of effectively extinguishing arcs. Background technique [0002] In the past, as an electromagnetic relay that effectively extinguishes an arc, for example, there is an electromagnetic relay characterized in that it has a first fixed contact and a second fixed contact facing each other across a first gap, and a contact between the first fixed contact and the second fixed contact is provided. The first movable contact between the second fixed contacts also has a third fixed contact and a fourth fixed contact facing each other through a second gap, and the third fixed contact and the fourth fixed contact are located between the third fixed contact and the fourth fixed contact. The second movable contact between them also has a permanent magnet that imparts magnetic flux in the same direction to the first gap and the second gap, and also ha...
