Electromagnetic relay

An electromagnetic relay, comprising:

• a base, at least one fixed conductive sheet assembly, at least one movable conductive sheet assembly, at least one arc blow component, an electromagnet and an outer cap, and the fixed conductive sheet assembly being disposed at the base and comprising a fixed connecting plate and a fixed contact, and the fixed contact being disposed at the fixed connecting plate and in the base;
• the movable conductive sheet assembly being configured to be corresponsive to the fixed conductive sheet assembly and disposed in the base and comprising a movable plate and at least one movable contact, and the movable contact being disposed at the movable plate and configured to be corresponsive to the fixed contact;
• the arc blow component being installed on an outer side of the base and disposed on a side of the fixed contact and the movable contact;
• the electromagnet being installed on a side of the movable conductive sheet assembly for driving the movable plate, so that the movable contact and the fixed contact form an electrical connection or disconnection by an electromagnetic effect;
• the outer cap being covered on the base, and the electromagnet being disposed in the outer cap, and the electromagnetic relay is characterized in that:
• the base is made of a polymer thermal conductive material, and the fixed connecting plate has a first heat conduction part and a second heat conduction part, which are provided for dissipating the heat generated during the electrical connection or disconnection of the movable contact and the fixed contact, wherein the first heat conduction part is disposed in the base, and the second heat conduction part is coupled to an end of the first heat conduction part and extended to an outer side of the base;
• and
• the electromagnetic relay further comprises at least two thermal conduction components, installed in the base and symmetrically configured with each other, and disposed on the two opposite sides of the fixed contact and the movable contact for dissipating heat.
