Abstract
Description
Technical Field
[0001] This utility model relates to the field of relay technology, specifically to a silent electromagnetic relay. Background Technology
[0002] Relays are a common electrical control component widely used in various electronic devices and circuits. When traditional relays are working, the closing and opening of their contacts will generate relatively obvious noise. In some environments with strict noise requirements, such as inside precision instruments and equipment, quiet offices, or smart home devices in home environments, this noise may interfere with the normal operation of the equipment or affect the quiet atmosphere of the surrounding environment.
[0003] Based on the above, the inventors have discovered the following problem: when using current relays, the closing of their contacts generates noticeable noise, affecting user experience.

[0008] Furthermore, the reset mechanism includes a first connecting plate, the bottom end of which is fixedly connected to the top end of the armature, a tension spring is installed on one end face of the first connecting plate, a second connecting plate is installed on one end of the tension spring, and the bottom end of the second connecting plate is fixedly connected to the top end of the yoke.
[0009] The beneficial effect of the above further scheme is that, through the setting of the first connecting plate, the tension spring and the second connecting plate, when the electromagnetic coil is powered off, the magnetic field disappears, and the armature can quickly return to the initial position under the elastic force of the tension spring.

[0012] Further, the bottom end of the base is installed with a pair of coil pins, and the coil pins are electrically connected with the electromagnetic coil through wires.
[0013] The beneficial effect of the above further scheme is that, through the setting of the first connecting plate, the tension spring and the second connecting plate, when the electromagnetic coil is powered off, the magnetic field disappears, and the armature can quickly return to the initial position under the elastic force of the tension spring.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This silent electromagnetic relay, by installing a buffer pad at one end of the iron core, plays a buffering role when the armature approaches or contacts the iron core, reducing the impact force and collision noise generated when the armature moves. The arrangement of the slide rod, retainer, and spring provides suitable elastic force for the stationary contact, which plays a buffering role when the moving contact contacts the stationary contact, reducing the impact force at the moment of contact, and reducing wear and noise. The arrangement of the first connecting plate, tension spring, and second connecting plate ensures that when the electromagnetic coil is de-energized, the magnetic field disappears, and the armature can quickly return to its initial position under the elastic force of the tension spring. The moving contact... Conductive silicone is installed on both the side of the stationary contact and the side of the stationary contact near the moving contact, ensuring good conductivity and stable circuit conduction during contact. It also acts as a buffer and reduces wear during contact. A shell is installed on the outer side of the top of the base to effectively protect the internal electromagnetic components. A pair of coil pins are installed at the bottom of the base to realize the external circuit of the electromagnetic coil. A moving contact pin is installed at the bottom of the base to realize the external circuit of the moving contact. A stationary contact pin is installed at the bottom of the base to realize the external circuit of the stationary contact. This utility model can effectively reduce noise during contact closure and avoid noise generation, and has high practical value. Attached Figure Description
