Electrical Moving Contact Rivets
Products Description
Electrical moving contact rivets are composite conductive components used in the movable ends of electrical contact systems. They consist of a contact material layer, a rivet base, a riveting structure, and a movable elastic element (if applicable).
Their main functions include:
Achieving circuit switching
Withstanding mechanical shocks
Resisting arc erosion during interruption
Maintaining long-term low contact resistance
Extremely high mechanical fatigue resistance
They are not merely a contact point, but a crucial "operating core" of the entire electrical system.
Key Features: Structural and Performance Characteristics Adapted to Dynamic Scenarios
Dynamic Contact Stability
The contact interface between the contacts and conductive components is dynamically optimized, maintaining stable contact even under high-frequency switching (more than 10 times per second) and vibration environments, eliminating the risk of poor contact.
Integrated Structural Design
Contacts, rivet substrates, and connecting clips (or welding bases) are integrally molded, eliminating the need for customers to assemble discrete components, reducing assembly errors and processes.
Wear and Fatigue Resistance
Both the contact surfaces and structural substrates are made of wear-resistant and fatigue-resistant materials, meeting the lifespan requirements of more than one million dynamic switching cycles.
Multi-Dimensional Adaptability
Compatible with different voltage levels (AC/DC 12V-800V) and current ranges (5A-150A), supporting multiple installation methods such as direct insertion, riveting, and welding, and adapting to the structural designs of different equipment.
Kinematic Engineering: Designed for Perfect Trajectories
Optimization of Inertia and Response Speed
In applications such as high-speed relays, we minimize the rotational inertia of moving components through topology optimization and lightweight design, thereby achieving faster response speeds and less contact bounce, maximizing the overall system performance.
Precise Control of Contact Trajectory
Through precise design of the head and rod geometry, we ensure that the contacts achieve minute "wiping" or "rolling" movements during closure. This not only breaks down the surface micro-oxide film, ensuring low contact resistance, but also effectively prevents welding caused by adhesion.
Stress Concentration Elimination
All our designs follow the principle of "smooth transitions," avoiding any sharp internal angles or abrupt changes in cross-section. Through FEA analysis, we ensure that stress is evenly distributed throughout the component, fundamentally preventing the initiation of fatigue cracks.
Deeply Adapted to Application Scenarios
High-Reliability Rotary Switches and Selectors
In instruments, test equipment, and control panels requiring frequent position switching, our components offer smooth operation and long-term stable contact performance. Especially in applications requiring multiple positions and fine resolution, our precision motion design ensures accurate positioning and a clear feel for each position.
01
Sliding Contacts and Busbar Systems
For applications such as linear motors, pantographs, and sliding connectors, our components solve the problems of rapid wear and unstable contact inherent in traditional sliding contacts. Through optimized contact surface geometry and self-cleaning design, we significantly extend maintenance intervals and improve the continuity of power transmission.
02
Limit Switches and Safety Interlocks
In industrial equipment safety systems, moving contact rivet assemblies are commonly used for position detection, door lock interlocks, and travel limit switches. Our products offer extremely high reliability and resistance to misoperation in these critical safety applications, meeting stringent safety standards through redundant design and failure mode control.
03
Miniaturized Precision Instruments
With the trend towards equipment miniaturization, traditional contact systems face space constraints. Our miniaturized mobile contact components integrate all the necessary functions in a tiny space, supporting the precision electrical control needs of next-generation portable devices, medical instruments, and aerospace equipment.
