What are Electric Vehicle Charging Riveting Contact Parts?
Electric Vehicle Charging Riveting Contact Parts provide the conductive interface used in EV charging circuits, battery management systems (BMS), and high-voltage power distribution units (PDU). The structure combines a copper substrate with a high-purity silver contact element and a mechanical riveting joint. Production covers stamping, contact riveting, dimensional control, and electrical or material inspection for charging-loop components requiring controlled current transmission and repeatable mechanical connection.
Core Product Structure For Custom Copper Stamping for EV Relays
Copper Substrate
The copper substrate forms the main conductive and mechanical body of the contact part. Its geometry can be produced by stamping and forming according to the relay, charging module, or PDU assembly drawing.
01
High-Purity Silver Contact Element
A high-purity silver insert forms the actual mating contact surface. Rather than producing the entire part from silver, the design places silver only at the electrical interface and uses another material for the structural body.
02
Mechanical Riveting Joint
Riveting mechanically fixes the silver contact element to the conductive substrate. The formed rivet must provide adequate retention without damaging the contact interface.
03
Stamped Support And Terminal Geometry
Depending on the assembly configuration, the stamped copper component can provide the electrical path, terminal connection, or mechanical spring function required by the contact structure.
04
Factory Manufacturing & Supply Capability of Copper Sheet Stamping for EV Relay
Stamping and Forming
Metal stamping supports production of the copper substrate, terminals, and structural contact components. Tooling can be configured around the customer's profile, hole pattern, bend geometry, and dimensional tolerance requirements.
Contact Riveting
Through contact riveting, the silver contact element is permanently joined to the stamped conductive body, forming a rigid, mechanically locked assembly. Engineers specify this process when the design demands fixed contact positioning, consistent geometry across production lots, and assured joint retention under repeated mechanical and thermal loading.
Tooling and Prototype Support
Engineering review can start from PDF, CAD, or 3D drawings. Tooling requirements, material selection, riveting sequence, and inspection points can be evaluated before sample production. Sample approval can then be used as the reference for subsequent production batches.
Production and Quality Systems
Manufacturing support includes stamping, contact riveting, material inspection, and finished-part testing. ISO 9001:2015 and IATF 16949 quality systems are available for applicable production programs, with RoHS and REACH requirements supported where specified.
Frequently Asked Questions about Moving Copper Contact Silver Plated for EV HVDC Contactor
What materials are used in Copper Sheet Stamping for EV Relay?
+
-
The source product uses a copper substrate combined with high-purity silver contacts. The copper provides the structural conductive body, while silver is positioned at the contact interface.
Can you substitute AgCdO with AgSnO2 to satisfy RoHS regulations?
+
-
Yes, we formulate high-density AgSnO2 compositions that match or exceed AgCdO arc-erosion resistance while remaining fully compliant with EU RoHS and REACH environmental directives.
How do you prevent oxidation on copper shanks during ocean transit?
+
-
All finished contact parts are passivated in an organic anti-tarnish inhibitor bath, sealed in anti-static vacuum nitrogen-flushed bags, and packed with silica gel desiccants.
What is the typical tooling and sampling lead time for a new shank geometry?
+
-
New cold-heading die development, sample forging, and metallographic validation require 10 to 15 calendar days from final CAD drawing approval.
