Mini high-power magnetic latching relay |
摘要 |
A mini high-power magnetic latching relay comprising a base seat, an insulation sleeve, a push rod, a magnetic circuit, and a contact part. The magnetic circuit comprises a magnetic enclosure, an iron core, a yoke, and a winding; the winding comprising a coil former and a coil wrapped on the coil former. One end of the yoke is a U-shaped end; the iron core penetrates through the coil for forming a fixed connection with the other end of the yoke; and one end of the iron core is located at the center of the U-shaped end to form an E-shaped gap. The magnetic enclosure is formed by magnetic steel and armature vertically located on both ends of the magnetic steel. |
