Problems solved by technology

Generally, the reeds of electromagnetic relays are suspended beam structures with low natural frequency. Vibration and impact can cause resonance, resulting in a drop in relay contact pressure, which is prone to instantaneous disconnection or jittering of contacts. In severe cases, structural damage can be caused. The armature part may cause malfunction and affect the reliability of the relay

Abstract

The invention discloses a novel relay iron core, which comprises a mounting shell, wherein the mounting shell is of a cuboid structure, a static contact plate, an armature, a connecting plate and a movable contact plate are arranged in the mounting shell, the static contact plate is close to one side of the mounting shell in the length direction, a coil is arranged in the mounting shell, the connecting plate is arranged at the top of the mounting shell and is close to the other end of the mounting shell in the length direction, one end of the armature is hinged with the connecting plate, a contact rod is arranged at the other end of the armature, and the contact rod penetrates through the top of the mounting shell. According to the invention, when the relay vibrates up and down, the counterweight ball swings up and down, and the contact head on the communication assembly I and the contact head on the communication assembly II move downwards, so that the number of turns of connection ofthe coil can be increased so as to increase the current intensity of the coil, the attraction of the coil to the armature is increased, the contact stability of the movable contact plate and the static contact plate is improved, and the relay can work more stably.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a novel relay iron core. Background technique [0002] Relays are widely used in home appliances, such as automobiles, air conditioners, color TVs, refrigerators, washing machines, etc.; they are also used in industrial automation controls and instruments. At present, mechanical stress has a great influence on relays on the market and materials, and mechanical stress refers to stress factors such as vibration, impact, and collision. Generally, the reeds of electromagnetic relays are suspended beam structures with low natural frequency. Vibration and impact can cause resonance, resulting in a drop in relay contact pressure, which is prone to instantaneous disconnection or jittering of contacts. In severe cases, structural damage can be caused. The armature part may cause malfunction and affect the reliability of the relay. Contents of the invention [0003] In order to solve th...
