Electromagnetic relays

Abstract

To provide an electromagnetic relay which can ensure an insulation distance between a yoke and a terminal while maintaining the width of the yoke as much as possible.SOLUTION: An electromagnetic relay comprises a base, a contact device, and an electromagnet device. The contact device is disposed on the base. The contact device includes a terminal supported by the base. The electromagnet device is disposed on the base. The electromagnet device includes: a coil; and a yoke disposed between the coil and the terminal. The yoke includes a first surface and a second surface. The first surface extends in a direction intersecting a first direction from the coil toward the terminal. The second surface extends from an end of the first surface in a second direction opposite to the first direction. The second surface includes an inclined surface. The inclined surface is disposed in the vicinity of the terminal and is inclined from the first surface in a direction away from an axis line of the coil.SELECTED DRAWING: Figure 3
