Abstract

The invention discloses a magnetic force system of an electromagnetic relay. The magnetic force system comprises a coil, an iron core, a yoke and an armature. The yoke comprises a first portion and a second portion which are connected to each other, the second portion of the yoke is connected to a first end of the iron core, and the first portion of the yoke extends along the length direction of the iron core and is spaced from the coil. The armature comprises a main body portion which faces the end surface of a second first end of the iron core, and a bending portion which bends at a predetermined angle from the main body part; and the surface of a section, arranged on the first portion of the yoke, of the bending portion of the armature faces the inner side of the iron core, and is opposite to the tail end part of the first portion of the yoke. According to the magnetic force system, the sectional area of a magnetic gap between the armature and the yoke is defined by the surface, facing the yoke, of the bending portion of the armature, thus the sectional area of the magnetic gap between the armature and the yoke can be enlarged by enlarging the surface area of the bending portion, so that the electromagnetic attraction of the yoke to the armature can be conveniently increased.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to a magnetic force system of the electromagnetic relay. Background technique [0002] The magnetic system of an electromagnetic relay generally includes an iron core, a coil, a yoke and an armature. The iron core passes through the coil, the yoke is connected with one end of the iron core, and the armature is arranged at the other end of the iron core and opposite to the end face of the other end of the iron core. [0003] In the existing electromagnetic relay, the surface of the armature is opposite to the end face of the yoke and is in contact with the edge of the yoke. Therefore, in the magnetic circuit of the existing electromagnetic relay, the magnetic gap between the armature and the yoke The cross-sectional area is limited by the area of ​​the end face of the yoke, that is to say, the cross-sectional area of ​​the magnetic gap between the armature and the yoke is limited by the t...
