1. Strengthen Connection Reliability and Solidify the Safety Foundation
The primary goal of industrial maintenance is to reduce unplanned downtime. A low-quality or failed terminal is one of the main sources of electrical faults.
Eliminate overheating hazards at the source: This is the most critical point. Low-quality terminals are often made of copper with insufficient purity, which has higher resistance and is prone to local overheating under high current. This not only wastes electrical energy but also accelerates the aging of insulation materials and can even cause fires.
Specific measures: High-conductivity copper (such as pure copper) should be used with high-quality plating (such as silver or tin plating) for terminals. Research shows that an appropriate silver plating process can significantly reduce contact resistance, thereby controlling temperature rise.
Specific benefits: Preventing failures caused by heating at connection points from the source minimizes fire risk and ensures production safety.
Improve durability in extreme environments: Under harsh conditions such as humidity, salt spray, and vibration, ordinary terminals are prone to oxidation or loosening, resulting in increased contact resistance up to failure.
Specific measures: Using corrosion-resistant plating (such as tin-nickel-silver triple plating) and multi-point contact terminal designs can ensure long-term stable connections. For example, some products maintain protection levels even after rigorous testing and achieve years of zero failures in high-salt environments.
Specific benefits: Significantly extend the maintenance cycle of equipment in harsh environments, reduce inspection and maintenance frequency, and enhance overall system reliability.
2. Reduce Energy Loss and Improve Energy Efficiency
In the context of achieving the "dual carbon" goals, it is crucial to explore energy-saving potential in every detail.
Directly reduce line loss: According to Joule's law, contact resistance is a direct cause of energy loss. A high-quality terminal means lower resistance, which means less electrical energy wasted in the line.
Specific measures: Using high-conductivity materials and optimizing the contact structure are key to reducing loss. Additionally, ensuring that connections are completely filled with no gaps (such as hot-melt solder devices) can also significantly reduce joint resistance.
Specific benefits: By directly reducing line losses, electrical energy is saved, and energy efficiency improvements are realized down to every connection point.
Support lightweight energy saving: In some emerging fields, terminal innovation offers new ideas for system-level energy saving.
Specific measures: For example, after upgrading to a 48V electrical architecture, thinner wires and innovative aluminum core or composite cable terminals can be used. Advanced plating technology eliminates electrochemical corrosion, ensuring performance while significantly reducing copper use and weight.
Specific benefits: By "lightening" the equipment, overall energy consumption is reduced. In some cases, simply replacing one type of high-performance terminal can save about 1,400 kWh per year per device.
