High-insulation small-sized hinged electromagnetic relay

A high-insulation small-sized hinged electromagnetic relay, comprising:

• a bobbin having an upper flange, a lower flange, and a cylindrical portion connected between the upper flange and the lower flange and used for winding a coil, and an axis of the cylindrical portion being vertically arranged;
• an iron core comprising a mandrel and a magnetic pole portion arranged on an upper end of the mandrel;
• the mandrel of the iron core being fitted into a central hole of the cylindrical portion of the bobbin, the magnetic pole portion of the iron core being positioned on the upper flange of the bobbin and positioned in a middle position in the width direction of the bobbin;
• coil terminals being assembled on the lower flange of the bobbin and positioned on one side in the width direction of the bobbin, and a part of the coil terminals being positioned in a winding window of the bobbin;
• and
• a fixed contact block being interposed in the upper flange and the lower flange of the bobbin and positioned on the other side of the bobbin in the width direction,
• wherein an axis of the cylindrical portion deviates to a direction away from the fixed contact block with respect to the central line of the width of the bobbin by a preset distance, so that an axial symmetric center of the mandrel of the iron core is offset from the axial symmetric center of the magnetic pole portion of the iron core by the preset distance, to increase a distance between the coil and the fixed contact block, increase a creepage distance between the coil and the fixed contact block, and improve insulation capability.
