A fixing frame for fixing at least a permanent magnet of a magnetic latching relay comprising:
- a body having a first surface and a second surface opposite to the first surface, and a shaft hole penetrating the first surface and the second surface, a rotating shaft of the permanent magnet being rotatably installed in the shaft hole;
- at least one longitudinal limit part arranged on the body;
- the longitudinal limit part comprising two vertical limit columns arranged oppositely along a longitudinal direction, the vertical limit column protrudes from the first surface away from the second surface, the two vertical limit columns being configured to clamp a yoke of the magnetic latching relay, and fit with the yoke without clearance in the longitudinal direction;
- and
- at least one transverse limit structure arranged on the body, and the transverse limit structure is configured to fit with a transverse fit structure of the magnetic latching relay without clearance in a transverse direction;
- wherein the transverse direction is perpendicular to the longitudinal direction.
A magnetic latching relay, comprising:
- a base;
- a permanent magnet installed on the base, the permanent magnet having a rotating shaft;
- two yoks fixedly installed on the base and located on opposite sides of the permanent magnet;
- a transverse fit structure located on the yok;
- and
- a fixing frame, comprising:
- a body having a first surface and a second surface opposite to the first surface, and a shaft hole penetrating the first surface and the second surface, a rotating shaft of the permanent magnet being rotatably installed in the shaft hole;
- at least one longitudinal limit part arranged on the body;
- the longitudinal limit part comprising two vertical limit columns arranged oppositely along a longitudinal direction, the vertical limit column protrudes from the first surface away from the second surface, the two vertical limit columns are configured to clamp a yoke of the magnetic latching relay, and fit with the yoke without clearance in the longitudinal direction;
- and
- at least one transverse limit structure arranged on the body, and the transverse limit structure is configured to fit with a transverse fit structure of the magnetic latching relay without clearance in a transverse direction;
- wherein the transverse direction is perpendicular to the longitudinal direction.
