Description

Technical Field

[0001] The utility model belongs to the field of relays, and in particular relates to an armature unit. Background Art

[0002] The armature is a key component in a relay that connects the moving and stationary irons. It converts the magnetic force generated by the electromagnet into mechanical motion through mechanical transmission. When the relay's control circuit is energized, the coil in the electromagnet generates a current, which in turn generates a magnetic field. This magnetic field attracts the armature, causing it to overcome the spring's pull and move the moving iron toward the stationary iron until it contacts the iron. At this point, the relay's contacts close or open, changing the on / off state of the controlled circuit. When the control circuit is de-energized, the electromagnet's magnetic field disappears, and the armature is no longer magnetically attracted. The spring's pull then returns the armature to its original position, separating the moving iron from the stationary iron. This restores the relay's contacts to their initial state, and the on / off state of the controlled circuit changes accordingly. In the relay industry, the armature unit is a key component, and its performance directly impacts the relay's reliability and lifespan. Traditional armature unit designs often suffer from unstable resetting and severe wear, particularly in high-frequency, high-load operating environments. These issues not only reduce relay efficiency but also increase maintenance costs. Therefore, developing an armature unit that ensures stable resetting is crucial. Summary of the Invention

[0003] The purpose of the utility model is to provide an armature unit, aiming to solve the problem of stable resetting of the armature unit.

[0004] To achieve the above objectives, the present invention provides an armature unit that is rotatably connected to an iron frame and comprises a main body, a support unit, a contact portion, and a hook member. The main body is provided with a support unit at each end, and the two support units are embedded in the iron frame and rotatably connected thereto. A hook member is provided at the upper end of the main body, extending downward, one end of which is connected to a spring for resetting. One end of the main body further extends upward to form an extension portion, which is bent to form a contact portion. The contact portion is located above the hook member, and a wear-resistant layer is provided on the side of the extension member proximal to the hook member.

[0005] Furthermore, the support unit is bent to form a raised portion, and a cylinder protruding outward is provided on the raised portion, and a communication port is formed by sequentially penetrating the raised portion and the cylinder.

[0006] Furthermore, the main body is provided with a plurality of riveting interfaces, which are designed to facilitate subsequent maintenance and replacement work.

[0007] Furthermore, one end of the hook is connected to the upper end of the body, and the other end is bent and extended outward to form a bent portion, on which a plurality of notches are arranged, and a clearance groove is provided in the hook. On the bent portion, a plurality of notches are arranged along its length.

[0019] In an embodiment of the present utility model, this case provides an armature unit that is rotatably connected to an iron frame, and includes a main body 100, a support unit 110, a contact portion 140, and a hook member 120. Support units 110 are provided at both ends of the main body 100, and the two support units 110 are embedded in the iron frame and rotatably connected thereto. A hook member 120 is provided at the upper end of the main body 100, and the hook member 120 extends downward, and one end thereof is connected to a spring for resetting. One end of the main body 100 also extends upward to form an extension portion 130, and the extension portion 130 is bent to form a contact portion 140. The contact portion 140 is located on the upper side of the hook member 120, and a wear-resistant layer 150 is also provided on the side of the extension portion 130 close to the hook member 120.

[0020] Specifically, support units 110 are provided at both ends of the main body 100. These support units 110 are embedded in the iron frame and rotatably connected thereto, ensuring the stable positioning and flexible rotation of the armature unit in the iron frame. The hook member 120 at the upper end of the main body 100 extends downward, one end of which is connected to a spring. The elastic force of the spring is used to achieve rapid resetting of the armature, thereby improving the response speed and stability of the relay. The extension portion 130 formed by the upward extension of one end of the main body 100 is bent into a contact portion 140. The contact portion 140 is connected and conductive to the stationary iron. This design optimizes the contact structure and reduces wear. At the same time, a wear-resistant layer 150 is provided on the side of the extension portion 130 close to the hook member 120, further enhancing the wear resistance.

[0021] Power-on stage: The electromagnet is energized, generating a magnetic field that attracts the armature unit, causing it to rotate and drive the moving contact to contact the static contact, and the circuit is turned on.

[0022] Working stage: The relay remains energized, the circuit continues to conduct, and the corresponding control tasks are performed.

[0023] Power-off stage: The electromagnet is powered off, the magnetic field disappears, the elastic force of the spring causes the armature unit to quickly reset, the moving contact and the static contact separate, and the circuit is disconnected.

[0024] In another embodiment of the utility model, the support unit 110 is bent to form a raised portion 160, which is provided with an outwardly protruding cylinder 170, which extends through the raised portion 160 and the cylinder 170 to form a communication port 180. The structure of the raised portion 160 and the cylinder 170 formed by the bending of the support unit 110 increases the contact area, connection strength, and smoothness between the armature unit and the iron frame, making the entire unit more stable and reliable.

[0025] In another embodiment of the utility model, the body 100 is provided with a plurality of rivet joints 190, and gaps are not formed at the rivet joints. The design of the rivet joints 190 facilitates subsequent maintenance and replacement work. When a component of the armature unit needs to be replaced or repaired, it can be quickly separated and reassembled by removing the rivets.

[0026] In another embodiment of the utility model, one end of the hook member 120 is connected to the upper end of the main body 100, and the other end is bent and extended outward to form a bending portion 200. A plurality of notched grooves 220 are arranged on the bending portion 200, and an air avoidance groove 210 is provided in the hook member 120. On the bending portion 200, a plurality of notched grooves 220 are arranged along its length. These notched grooves 220 can be rectangular, circular or other shapes, and the specific shape and size depend on the subsequent use requirements and process requirements. The design of the notched groove 220 can reduce the weight of the hook member 120, while providing a certain amount of elastic deformation space, which helps to absorb vibration and impact. The notched groove 220 can be combined with a spring, and the spring is wound around the notched groove 220 to form an elastic reset, so the notched groove 220 provides a space for the spring. The design of the air avoidance groove 210 can reduce the stress concentration phenomenon of the hook member 120 when it is subjected to external force, reduce the risk of fatigue damage, and increase its service life.

[0027] In another embodiment of the utility model, an upwardly extending expansion portion 230 is provided at the upper end of the contact portion 140 to increase the contact area with the stationary iron and enhance the connection stability.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
