Tin-plated Copper End Cap
Tin-plated copper end cap is a precision stamped conductive internal component designed specifically for various circular fuses and fuses. As the core connection and structural support component inside the fuse, it undertakes key functions such as melt conductive connection, tube positioning, sealing adaptation, and assembly positioning. The product is made of 99.99% high-purity T2Y2 copper as the substrate, combined with tin plating surface treatment process. With precise size control, excellent conductivity and stable assembly compatibility, it has become the core supporting choice for global fuse manufacturers and new energy equipment manufacturers.

Product Introduction
Tin-plated copper end cap is a key internal contact component in fuse assemblies, and its core value lies in solving oxidation, poor welding, and compatibility issues during fuse assembly through high-purity substrates and customized surface treatments. The core features of the product are built around three dimensions: assembly compatibility, long-term reliability, and batch consistency. As the "intermediate bridge" connecting the melt and the outer cap, the conductivity, corrosion resistance, and fitting accuracy of the inner cap directly determine the long-term reliability of the fuse.
Application Scenarios
photovoltaics (PV fuses)
Tin-plated copper end cap is suitable for photovoltaic combiner boxes, string inverters, and front-end protection fuses. It can withstand DC1000V/1500V high voltage, withstand outdoor high and low temperature, humid and hot environments, and ensure stable power supply for photovoltaic systems.
01
new energy vehicles (EV fuses)
It equipped with on-board PDUs, battery packs, high-voltage distribution circuit fuses, in compliance with IATF16949 automotive grade standards, suitable for vibration, high and low temperature cycling conditions, ensuring the safety of the on-board power system.
02
Energy storage field (energy storage fuse)
Outer end cap is used for energy storage cabinets, battery clusters, BMS system fuses, suitable for DC high current transmission, controlling abnormal temperature rise, and avoiding the risk of short circuit in energy storage systems.
03
industry and industrial control
End cap copper is compatible with PDU distribution units, UPS DC links, NH series, BS series, and fast fuses to meet the long-term stable operation needs of industrial plants, communication rooms, and industrial control equipment.
04
Core selection parameters
Core substrate parameters (mandatory)
Our Copper metal end cap substrate is made of 99.99% copper T2Y2 (SECu/C1100) high-purity purple copper, with a conductivity of% IACS ≥ 97 and a Vickers hardness of HV 80-110s. It balances excellent conductivity and stamping formability, ensuring product assembly compatibility and long-term reliability from the source.
