In electrical control systems, relays are crucial components for circuit switching and signal control, and the stability of their internal structure directly impacts the reliability of equipment operation. Among these components, the moving reed assembly is a key element in the relay's conduction and disconnection actions. In recent years, with the miniaturization, high-frequency operation, and high reliability of electrical equipment, the traditional moving reed structure has gradually revealed limitations in stability and durability. Therefore, optimizing the moving reed assembly structure has become a key focus in the industry.
During the actual operation of a relay, when the coil is energized, it generates an electromagnetic force that attracts the armature downwards, causing the moving contact to contact the stationary contact and form an electrical circuit. When the coil is de-energized, the electromagnetic force disappears, and the moving reed, relying on its own elasticity or spring structure, resets the armature. During this repetitive motion, the armature's trajectory must remain stable; otherwise, problems such as poor contact, accelerated wear, or even electrical failure can easily occur. Therefore, achieving precise limiting while ensuring structural strength has become an important technical direction in the design of moving reed assemblies, and it directly affects the performance of key components such as Electrical Stamping Contact Components and Stamping Electrical Contacts.
The new structural design incorporates a reinforcing shim between the moving spring body and the armature, and a folded structure forms a limiting protrusion that precisely engages with the limiting groove on the armature. This design not only enhances the overall strength of the riveted structure but also achieves precise armature positioning. In actual operation, the limiting protrusion, embedded in the groove, effectively reduces movement offset and improves contact consistency. This structural improvement is significant for components requiring high-reliability conductivity, such as Electrical Stamping Contact for Relay and Metal Parts Silver Contact.
In addition to strengthening the structure, this moving spring assembly also features a limiting block at the other end of the armature, which engages with the internal support structure of the relay to laterally constrain armature movement. Combined with the guide structure on the yoke, the armature maintains a stable trajectory during vertical movement, reducing sway. This design concept is becoming increasingly common in modern relay manufacturing, particularly in high-precision conductive components such as Silver/Copper Metal Parts for Switches and Relays, where it significantly contributes to stable contact pressure and extended service life.
Regarding the connection method, the moving spring body adopts a multi-point riveting structure, fixed to the armature through triangularly distributed riveting points, making the overall structure more stable. Multi-point connection effectively disperses stress, maintaining reliable connection even under frequent operation. This structural form is widely used in precision contact assemblies such as Riveted Electrical Connection Components and Silver Contact Riveted Assemblies. Furthermore, optimizing the structure of the riveting area improves production consistency, making the product more suitable for automated manufacturing environments.
To further improve assembly accuracy, a receiving groove structure is designed on the armature surface, allowing the moving spring body to be embedded and positioned within it. The riveting post is located at the bottom of the groove and is fixed through hole fitting. This design prevents the assembly from rotating or shifting after riveting, thereby improving overall stability. In precision relay manufacturing, this type of structure is common in the production processes of high-consistency products such as In-Die Electrical Riveting Contacts and Electrical In-Die Riveted Connections.
Furthermore, to reduce forming resistance during riveting, a countersunk hole structure is designed on the back of the armature, providing sufficient space for the riveting post to deform, thereby reducing processing stress and improving riveting smoothness. This structure not only improves production efficiency but also reduces material fatigue. Similar technology is also commonly used in the manufacturing process of In-Die Rivet Electrical Contacts and In-Mold Riveting Components to meet the demands of high-speed stamping production.
Regarding the moving spring structure, the design of reinforced convex edges on both sides further enhances overall rigidity and provides reliable support for riveting. The accompanying beryllium copper elastic material maintains conductivity while providing good springback capability, and is therefore commonly used in critical components such as Beryllium Copper Stamping Springs and Beryllium Copper Punch Contact Riveted Terminals. In the automotive electronics field, this structure is also suitable for high-reliability scenarios such as Moving Spring Assemblies for Automotive Relays.
With the development of precision stamping and automated assembly technologies, an increasing number of relay components are being manufactured using in-mold riveting processes. By integrating stamping and riveting, a stable in-mold riveting electrical contact structure can be formed, while simultaneously improving production efficiency and reducing manual intervention. This technology has become an important development direction for contact components such as Copper Beryllium Riveting Silver Contacts, which require mass production.
Overall, riveted components, through reinforced gasket limiting structures, multi-point riveting methods, and guiding designs, ensure the armature maintains a stable movement trajectory during operation, while improving structural strength and assembly accuracy. This technology not only improves the reliability of relay contact systems but also provides new ideas for the development of precision stamped contact components. As the requirements for reliability and lifespan of electrical equipment continue to increase, this type of structural innovation will be more widely applied in the field of relays and related electronic components.
