High-thrust electromagnet for low-voltage apparatus

Abstract

The invention relates to a high-thrust electromagnet for a low-voltage apparatus. A closed shell is mounted on a base of the low-voltage apparatus; a magnet exciting coil is mounted in the closed shell; a movable iron core and a static iron core are arranged in the magnet exciting coil; a magnetic conducting end cover is mounted on one side of the closed shell; the movable iron core penetrates through the magnetic conducting end cover; the static iron core is fixedly mounted on the other side wall of the closed shell; the movable iron core is fixedly connected with one end of a moveable push rod; the other end of the moveable push rod penetrates through an inner hole of the static iron core and is hinged to a connecting rod; a resetting spring sleeves the moveable push rod; the two ends of the resetting spring are respectively jacked between the movable iron core and the static iron core; a sliding sleeve sleeves in a skeleton of the magnet exciting coil; an outer circle of the movable iron core sleeves in the sliding sleeve in a sliding form; the moveable push rod penetrates through the inner hole of the static iron core in a sliding form. The high-thrust electromagnet for the low-voltage apparatus has the advantages of higher working efficiency, excellent stability and longer service life.

Description

technical field [0001] The invention relates to an electromagnet, in particular to a high-thrust electromagnet used for low-voltage electrical appliances, and belongs to the field of low-voltage electrical appliances. Background technique [0002] An electromagnet is a widely used electrical component, mainly used as a power component or an actuator. Its working principle is to use the magnetic field generated by the energized coil to attract the magnetically conductive material placed in the coil, so as to achieve the purpose of work. Since the moving iron core needs to move inside the coil, it is necessary and the coil frame inside the coil is made of insulating materials, and the deformation caused by the excessive temperature rise will be considered accordingly, so there will be a gap between the iron core and the coil during design. Leave a large gap, which will cause the effective attraction of the electromagnetic field to the iron core and reduce the working efficienc...
