Abstract

An electromagnetic relay includes a yoke having both ends bent in first direction, a coil portion wound onto a central part between the ends of the yoke, a permanent magnet arranged between the ends of the yoke, an armature formed to have a greater length than that between the ends of the yoke and provided on the first side of the permanent magnet and a hinge spring capable of causing both end sides of the armature to be toggle with respect to the ends of the yoke, and the hinge spring integrally fixing the permanent magnet and the armature.

Description

technical field [0001] The invention relates to an electromagnetic relay. The relay is composed of a yoke, a coil part, an armature, a movable contact and a fixed contact. The coil part is wound on the yoke, and the armature is fixed relative to the yoke. The action makes the movable contact and the fixed contact in contact and separation state. Background technique [0002] Figure 1 to Figure 3 A conventional type of electromagnetic relay is shown. The electromagnetic relay consists of a yoke c having a winding space divided by a bobbin A, on which a coil B is wound, and provided with pole parts C1 and C2 at both ends, which are attracted to the pole parts C1 and C2 of the yoke C. A pair of armatures D1 and D2 in and separated from C2 rotate according to the excitation state of the coil B; a fixed contact piece E provided with a fixed contact E1; a movable spring F provided with a movable contact opposite to the fixed contact E1 F1; and the card G connected to the armatu...
