Title:
ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2018/040872
Kind Code:
A1
Abstract:
An electromagnetic relay, comprising a movable spring (1), a yoke (2), and a coil (3). An iron core (7) is provided in the coil (3); the yoke (2) is L-shaped and has horizontal edges and vertical edges; the yoke (2) is provided outside the coil (3); the horizontal edges of the yoke (2) are fixedly connected to the bottom of the iron core (7), and the vertical edges of the yoke (2) are parallel to the axis of the iron core (7); one side of the vertical edges of the yoke (2) facing towards the coil (3) is provided with a plastic layer (61) formed by means of injection molding, such that the plastic layer (61) is provided between the yoke (2) and the coil (3) in an insulating manner. The solution can improve the insulation degree between the yoke (2) and the coil (3), ensure position precision of an insulating component, and effectively reduce assembly processes, without influencing winding space. On the other hand, when the yoke (2) and the movable spring (1) are fixed, no stress will be applied on the movable spring (1) to deform the movable spring (1), such that the dimensional uniformity of the movable spring (1) is improved.
