The invention relates to the technical field of relays and particularly relates to a moving iron core built-in relay which comprises a base and also comprises an electromagnet, a static terminal and an elastic terminal arranged on the base. The electromagnet comprises a frame, a coil, a fixed iron core and a moving iron core. One end of the fixed iron core extends into the frame, and the moving iron core is movably arranged in the frame. One end of the fixed iron core is used for attracting one end of the moving iron core, and the other end of the moving iron core protrudes out of the frame. The moving iron core of the relay of the invention is movably arranged in the frame, after the coil is electrified, one end of the fixed iron core generates magnetism to attract one end of the moving iron core, thus the moving iron core moves relative to the frame, and the moving iron core in movement drives the elastic terminal to switch on the static terminal. In the process that the moving ironcore moves, the frame is used to limit the moving iron core, the extra set of a structure for limiting the moving iron core in the relay is not needed, the structural design of the relay is simplified, and the manufacturing cost of the relay is reduced.
Description
technical field [0001] The invention relates to the technical field of relays, and in particular discloses a relay with a built-in moving iron core. Background technique [0002] As the "automatic switch" in the circuit, the electromagnetic relay is already one of the essential basic components in many electronic devices; most electromagnetic relays include magnetic components, armatures and contact components. When the magnetic components are energized, the magnetic components generate magnetic Then drive the armature to move, and the moving armature drives the contact assembly to realize the conduction or disconnection of the contact assembly; in the manufacturing process of the electromagnetic relay, it is necessary to additionally design a limit structure for the limit armature to prevent the armature from excessively moving. In order to realize the stable conduction or disconnection of the contact assembly. The structure of the limiting mechanism used for limiting the ...
