Problems solved by technology

However, most of the existing permanent magnet relays rely on the leakage magnetic field of the magnet to cooperate with the external excitation magnetic field, which greatly reduces the use efficiency of the magnet and cannot make full use of the magnetic properties of the magnet, and in the released state The holding force of the lower armature is not enough, and the anti-vibration and shock performance is relatively weak

Abstract

The invention discloses a permanent-magnet-containing balance armature relay electromagnetic structure and belongs to the technical field of relays. An armature is arranged at one side of an upper yoke and a lower yoke, the middle part of the armature is rotatably supported on an outer frame through a rotating shaft, the two ends of the armature are arranged with the upper yoke and the lower yoke in an opening and closing manner respectively, the magnetic steel is arranged on the lower yoke and is connected with the middle part of the armature through a magnetic conductive piece, and the magnetic steel is close to the armature close to one end of the lower yoke. The magnetic flux generated by the magnetic steel can be effectively utilized, so that magnetic leakage waste is avoided, the magnetic circuit efficiency is improved, the relay power is reduced, the environment resistance of the relay is improved, and the problems that an existing relay is low in release retention, poor in vibration and impact resistance, high in power consumption and the like are solved.

Description

Technical field [0001] Technical Field The present invention belongs to the relay, in particular, it relates to a permanent magnet balanced armature structure having an electromagnetic relay. Background technique [0002] The relay itself by the electromagnetic system and the contact spring system components, an electromagnetic relay system input portion receiving an external voltage or current excitation motion so as to drive the whole relay; contact spring system relay output portion, so that close and open the contacts through control contacts off both ends of the signal. Currently available can be divided into small relay and relay-free relay comprising two permanent magnets, electromagnetic systems are mainly containing magnets. [0003] An electromagnetic relay system does not contain a permanent magnetic field inside the magnetic circuit is completely generated by the external excitation configuration, operation of the electromagnetic energy provided by the system is compl...
