The invention discloses an electromagnetic relay with relatively high anti-adhesion capability. The electromagnetic relay comprises a base, a movable spring component, a fixed spring component and a push card, wherein a moveable spring plate is of a sheet structure and a movable contact is arranged at one side of the movable spring plate; the push card is matched close to the other side of the movable spring plate; two push arms toward the movable spring plate protrude on the push card and correspond to two sides of the movable contact separately, wherein the protruding size of one push arm is greater than that of the other push arm, so that the part, close to one push arm, in the movable contact is firstly in contact with a fixed contact, and the part, close to the other push arm, in the movable contact is lagged and then is in contact with the fixed contact to form movable and fixed contact rolling contact when the push card pushes the movable spring plate and the movable contact is in contact with the fixed contact, thereby preventing contact adhesion under capacitive load. The electromagnetic relay has relatively high contact anti-adhesion capability, thereby effectively ensuring the usability of the relay.
Description
Technical field [0001] The present invention relates to the technical field of relays, in particular to an electromagnetic relay with strong anti-adhesion ability. Background technique [0002] The relay is a breaking and closing device that can frequently close, carry and break normal current and specified overload current. An existing electromagnetic relay is an electrical appliance that uses current to flow through a coil to generate a magnetic field and close the contacts to control the load. It is widely used in the fields of electric power, power distribution and electricity consumption. The basic working principle of electromagnetic relay is to convert electrical energy into magnetic energy and then into mechanical energy, and use mechanical energy to connect and break the controlled circuit to realize the function of "relay". [0003] The existing electromagnetic relay usually includes a base, a magnetic circuit part, a contact part and a pushing mechanism. The pushing me...
