Problems solved by technology

The defect of the existing electromagnetic tripper is: because the armature of the electromagnetic tripper is in the process of attracting or separating from the yoke, the sudden recoil force of the spring will easily cause the armature to jump, deviate from the neutral position, and reduce the electromagnetic tripper. running stability

Embodiment Construction

[0022] like Figure 1-7 As shown, an electromagnetic tripper includes a housing 1 and a base 2 to form an accommodation space, and a coil 41 wound on a coil frame 4, a yoke 6, an armature 5, a magnetic steel 7, and a tension spring 10 are arranged in the accommodation space. , a push rod 3 placed on the top of the casing 1 can move upwards under the action of the armature 5, the yoke 6 is U-shaped, the first arm of the yoke 6 extends into the through hole of the bobbin 4, the yoke 6 The pressure reed 9 is fixedly installed on the second arm, the upper end of the pressure reed 9 forms shoulders 91 on both sides, and the shoulders 91 on both sides stretch into the hinge groove of the armature 5, and the top plate of the coil bobbin 4 is close to the positions on both sides of the front end of the armature 5 respectively. Bumps 42 are formed.

[0023] The top plate of the bobbin 4 is provided with an opening 43 , the bottom plate of the bobbin 4 is provided with a slot 44 opposi...

Abstract

The invention relates to an electromagnetic release which comprises a housing and a base which form an accommodating space. A coil wound on a coil framework, a yoke, an armature, magnetic steel and a tension spring are arranged in the accommodating space. An ejector rod penetrating through the top end of the housing can move upwards under the action of the armature. The yoke is U-shaped. A first arm of the yoke extends into the through hole of the coil framework. A pressure reed is fixedly mounted on the side surface of a second arm of the yoke, and two shoulder parts are formed at the upper end of the pressure reed and extend into a hinging groove of the armature. Lugs are respectively formed on the two sides, close to the front end of the armature, of a top plate of the coil framework. The lugs are arranged at the position close to the front end of the armature, so that the armature is prevented from generating transverse deviation, the armature is limited to rotate on a middle plane, and the stable rotation of the armature is effectively ensured.

Description

technical field [0001] The invention relates to an electromagnetic release. Background technique [0002] The electromagnetic release is a kind of release. When the coil is not energized, the magnetic circuit assembly is magnetized by the magnetic steel, so that the armature and the yoke are attracted. When the coil is energized, the magnetic field force induced by the coil is enough to overcome the force of the magnetic steel. Under the action of the tension spring, the armature quickly slaps the ejector rod, so that the ejector rod moves upwards to drive the mechanism to move, and then cut off the circuit. The defect of the existing electromagnetic tripper is: because the armature of the electromagnetic tripper is in the process of attracting or separating from the yoke, the sudden recoil force of the spring will easily cause the armature to jump, deviate from the neutral position, and reduce the electromagnetic tripper. operation stability.
