Silver Contact Riveted With Copper Terminal
Products Description
Silver Contact Riveted with copper terminals consist of two core functional components: silver-based contacts and brass/copper terminals. These are firmly joined through a cold riveting process, resulting in a compact structure, short conductive path, and low heat generation, ensuring long-term operation.
Key features include:
Bimetallic structure with excellent conductivity: The contact surface uses silver or a silver alloy, while the bottom terminal uses pure copper or a copper alloy, ensuring high conductivity, low contact loss, and uniform current distribution.
Mechanical locking riveting: The cold riveting process creates a mechanical lock between the metals, eliminating the need for solder, resulting in better vibration resistance and a longer service life.
Strong arc resistance and anti-welding properties: The silver-based material can withstand frequent opening and closing, arc impacts, and high-current transient impacts, significantly reducing the risk of Copper Contact Riveting adhesion.
Material and Functional Zoning for Precise Matching of Connection Needs
The product adopts a functional combination design of "silver contacts + copper terminals." The two materials each perform their specific functions while working synergistically to balance conductivity, connection reliability, and application adaptability:
Silver Contacts: Utilizing high-purity silver (≥99.9%) or customized silver alloys (silver-nickel, silver-tin oxide, etc.), the core advantages are "low contact resistance, high oxidation resistance, and resistance to arc erosion." As the direct current contact carrier, silver minimizes signal/current transmission loss, especially in high-frequency switching or high-current scenarios, effectively suppressing arc erosion of the In-Die Stakings and preventing signal distortion or circuit failure due to poor contact. Customized silver alloys enhance performance for special scenarios (such as corrosive environments and high-frequency vibration), improving product adaptability.
Copper Terminals: Utilizing TU2 high-conductivity copper or copper alloys, focusing on "high current carrying capacity, excellent ductility, and wiring adaptability." Copper terminals, as current conductors and wiring carriers, possess excellent electrical and thermal conductivity, can safely carry rated current, and quickly dissipate working heat. At the same time, the ductility of copper ensures that the terminals are not easily broken or deformed during wiring crimping or plugging. Furthermore, the Silver Contact Riveted Copper Stamping Parts structure can be customized according to the wiring method (crimping, welding, plugging) to adapt to different specifications of wires and equipment interfaces.
In-depth Technical Features
Perfect Pre-formed Integration
Riveting itself is a core technical feature. Riveting completed in a constant temperature, constant pressure, and clean production environment results in bonding strength and electrical performance far superior to manual or semi-automatic on-site operations. This is a "one-time investment, lifelong benefit" quality assurance.
Superior Heat Conduction Path
Heat generated at the Copper Pressed Components is seamlessly conducted through the perfectly formed riveted joint to the copper terminals, which have a larger surface area and heat capacity, and then rapidly dissipated. This optimised thermal management path is key to reducing switch temperature rise and improving equipment operational stability.
Integrated Traceability
Each batch of Custom Copper Stamping has a unique identification code, recording the batch number of the silver contacts, the batch number of the copper terminals, the production time, equipment parameters, and quality inspection data. This provides you with end-to-end quality assurance capabilities, tracing back from finished products to raw materials.
Design Advantages: The Ultimate Embodiment of Engineering Thinking
Optimised Stress Distribution
The contact surfaces of terminals and Copper Stamping for switches feature a gradual transition design, avoiding stress concentration points and extending product lifespan.
Self-Cleaning Effect
A minute mechanical interlocking structure generates slight displacement during each insertion and removal, creating a self-cleaning effect and preventing the accumulation of dust and oxides.
Precise Insertion and Removal Force Control
Through geometric design, insertion and removal forces are ensured to remain within the range of 0.5-1.2N, guaranteeing connection reliability while preventing damage to equipment from excessive forces.
Modular Design
Silver Electrical Riveted Components are Adaptable to various standard terminal sizes, supporting rapid switching to meet diverse customer customisation needs.
