Ceramic Fuse Holder
Products Description
Ceramic fuse holders with copper contacts, as core safety protection components of electrical systems, undertake four core missions: overload fuse triggering, high-temperature insulation isolation, low-resistance stable conduction, and fault-safe isolation. They are crucial for ensuring circuit systems achieve rapid overload response, no arcing risk, and long-term stable operation. Essentially, through the integrated design of a high-insulation ceramic shell and high-conductivity copper contacts, they achieve precise fuse mounting while addressing the pain points of traditional fuse and fuse holder under high-voltage, high-temperature, and vibration conditions, such as excessive contact resistance, insulation ageing, and arcing ignition.
Product Materials and Structure
High-Purity Ceramic Body
Utilising high-temperature sintered alumina ceramic, its temperature resistance far exceeds that of plastic parts, maintaining electrical insulation even under sustained high temperatures.
The ceramic surface has high hardness, wear resistance, and does not age, making fuse and holder suitable for long-term use.
Low water absorption ensures excellent electrical performance even in humid and hot environments.
High insulation strength effectively prevents arcing along the surface and breakdown.
High-Conductivity Copper Fuse Base
Made from high-purity copper through stamping or precision CNC machining, offering excellent conductivity and extremely low contact resistance.
Good flexibility, able to withstand installation stress and mechanical impact.
The surface can be protected with tin, silver, etc., to improve oxidation resistance and conductivity stability.
Robust Structural Design
The ceramic body and fuse holder fuse structure fit tightly together, maintaining high strength and mechanical stability.
Multiple mounting slots, clips, and positioning structures improve assembly efficiency.
The internal cavity structure can be customised according to fuse specifications to ensure a tight fit of the fuse element and enhance conductivity reliability.
Manufacturing Advantages: Fusing Precision Craftsmanship into Every Detail
Ceramic Precision Moulding and Sintering Technology
We employ isostatic pressing and high-temperature sintering processes to manufacture ceramic matrices that are high-density, high-strength, and free of micro-cracks. Precision moulds ensure dimensional accuracy, providing a perfect foundation for subsequent metal component assembly.
High-Precision Metal Component Machining and Electroplating
fuse holder with fuses are machined using high-precision stamping or CNC machining, ensuring consistency in size and shape. Automated electroplating production lines provide uniform, highly adhesive tin or silver plating layers, ensuring long-term conductivity and oxidation resistance.
Automated Assembly and Testing
Key assembly processes, such as the pressing or riveting of metal holder fuses to ceramics, are completed by automated equipment, ensuring that the contact pressure and assembly precision of each product meet design requirements. The production line integrates electrical performance, withstand pressure, and insertion/extraction force testing.
Rigorous reliability verification
Before mass production, every new product must pass rigorous life tests, temperature rise tests, vibration tests, and salt spray tests to ensure that fuse with holder performs excellently in various simulated real-world applications.
