The invention relates to the technical field of relays, and particularly discloses an electromagnetic relay with an improved magnetic circuit. The circuit comprises a terminal module, a magnetic circuit module and an armature module, the magnetic circuit module is detachably connected with the terminal module, and the armature module is detachably connected with the magnetic circuit module; the armature module comprises a limiting piece and an armature piece, and the limiting piece is detachably connected to the magnetic circuit module; the limiting piece is provided with a sliding hole, the armature piece rotates and is movably located in the sliding hole, and the armature piece is provided with an arc-shaped part; the limiting piece is provided with a protruding piece which abuts againstthe armature piece so that the arc-shaped part can abut against the magnetic circuit module in a rolling mode. In the using process of the electromagnetic relay, the magnetic circuit module drives the armature piece to rotate, the rotating armature piece rolls relative to the magnetic circuit module through the arrangement of the arc-shaped part, abrasion and friction noise between the armature piece and the magnetic circuit module are reduced, it is ensured that the armature piece can rotate easily, and the reaction sensitivity of the electromagnetic relay is improved.
Description
technical field [0001] The invention relates to the technical field of relays, and in particular discloses an improved magnetic circuit electromagnetic relay. Background technique [0002] The relay is a commonly used basic component as an automatic switch in the circuit. There are many types of relays, and the electromagnetic relay is a commonly used one. The electromagnetic relay needs to be equipped with an armature. During the use of the electromagnetic relay, the electromagnetic relay needs to use the magnetic force to drive the armature to move. , the moving armature drives the terminal assembly on or off. The armature installation structure design of the electromagnetic relay in the prior art is unreasonable, which causes the movement of the armature to be laborious, which will greatly cause the hysteresis of the armature movement, cause the sensitivity of the electromagnetic relay to be greatly reduced, and seriously cause safety hazards. Contents of the invention ...
