Copper Holder For Knife Blade Type Fuse Link
Products Description
The Copper Holder for Knife Blade Type Fuse Link uses high-purity T2Y2 copper as the main conductive material, integrally formed through precision stamping and tapping processes. Combined with optimised structural design, it achieves engineering-grade application standards in terms of mechanical strength, electrical performance, and assembly compatibility.
The product features a compact overall structure and optimised contact surfaces, enabling a large-area, tight fit with blade fuses, significantly reducing contact resistance and temperature rise. Simultaneously, the base has pre-drilled standard mounting holes and threaded interfaces for convenient system integration and field installation, suitable for various electrical architectures.
Its structural features include:
High-precision dimensional control in the blade insertion area ensures fuse insertion and removal stability.
Integral stamping of the copper body eliminates welding points, reducing the risk of discontinuous conductive paths.
Key Technical Features: Dual Redundancy of Electrical and Mechanical Elements
High-Precision Flexible Clamping
For the insertion and removal cycles of the Fuse Holder for NH Fuse, we precisely control the springback of the stamped parts, ensuring that the clamping force remains within the rated range after multiple fuse replacements, preventing thermal runaway caused by increased contact resistance.
Integrated Tapping Structure
Employing synchronous tapping technology, both thread depth and perpendicularity are precisely calibrated. Compared to traditional welded nuts, integrated tapping provides a better heat conduction path and stronger resistance to torque damage for NH Fuse Holder Silver-plated Contacts.
Optimised Electromagnetic Loss
The non-magnetic properties of copper avoid hysteresis losses in high-frequency or alternating current environments, reducing the temperature rise of the base itself.
Application Advantages: Proven Mechanical Reliability in Harsh Conditions
| Photovoltaic and Energy Storage Inverters | In harsh outdoor environments with high and low temperature cycles and high salt spray, the elasticity of ordinary fuse holders easily deteriorates. Our NH Fuse Base Square Pipe Knife's high resistance to stress relaxation ensures that the DC and AC fuse holders do not overheat or loosen throughout the inverter's 25-year lifespan, eliminating the need for frequent maintenance of high-altitude equipment. |
| Heavy Industrial Drives and Metallurgical Power Distribution | In the distribution cabinets of rolling mills or cranes with frequent start-stop cycles and significant mechanical vibrations, the Square Pipe Knife-Shape Contact for NH Fuse need to withstand continuous mechanical impacts. Our one-piece, thick-material stamping structure demonstrates a seismic life far exceeding that of spliced components, ensuring absolute stability of contact resistance under strong vibrations. |
| High Current Distribution and Reactive Power Compensation | In power distribution systems with capacities of several thousand amperes, the connection between the Blade Contact for Ceramic Fuse Base and the external busbar is a major area prone to thermal runaway. Our base features a large, flat back surface and high-precision tapping, ensuring 100% surface fit with the external tin-plated copper busbar and eliminating localised hot spots caused by uneven mounting surfaces. |
Detailed Display and Quality Control
Crank Arm Rounded Transition
At the root of the clamping arm, the corner formed by stamping should be a rounded transition, not a sharp corner. Sharp corners cause stress concentration and are prone to cracking after repeated insertion and removal. Our moulds ensure that all corner radius (R) is ≥0.5mm.
Contact Surface Imprinting
In the area in contact with the Knife Type Contact for Fuse Link Base Holder, fine imprinted textures or pitting can be added to increase the actual number of contact points, reduce contact resistance, and provide a certain degree of self-cleaning (friction removes the oxide film during insertion and removal).
Thread Depth Marking
After tapping, the thread specification and depth markings are imprinted on the side of the base for quick identification by on-site installers.
Chamfered Anti-Scratch
All entry edges (fuse insertion port, mounting hole edges) are chamfered or rounded to prevent scratching the cable insulation or operator gloves during installation.
