The conductive principle of Copper-Aluminum Terminal and its role in reducing power loss in electrical connections mainly benefit from the following characteristics and design:1. Excellent electrical conductivityHigh electrical conductivity of copper: Copper is a metal with extremely high electrical conductivity and is the non-precious metal with the best electrical conductivity. Copper terminals take advantage of copper's high conductivity to effectively reduce resistance, thereby reducing power loss.Good electrical conductivity of aluminum: Although aluminum has slightly lower electrical conductivity than copper, its low density, light weight, and relatively low price make it widely used in some applications. Aluminum terminals can also achieve lower resistance and power loss through certain surface treatment and connection technology.2. Low resistance designReduced contact resistance: Copper-Aluminum Terminal focuses on reducing contact resistance during the design and manufacturing process. Through precision machining and surface treatment (such as silver plating, tin plating, etc.), the resistance at the interface is reduced to ensure that the current does not cause significant resistance loss when passing through the connection point.Large area contact: Copper-Aluminum Terminal is usually designed for large area contact to increase the conductive area of the contact point and reduce resistance. Large-area contacts can effectively disperse current and reduce local resistance, thereby reducing power loss.3. Corrosion resistanceAnti-corrosion treatment: Copper-Aluminum Terminal usually undergoes anti-corrosion treatment on the surface, such as nickel plating, zinc plating, etc., to prevent oxidation and corrosion. The oxide at the copper-aluminum interface will significantly increase the resistance. Through anti-corrosion treatment, the low resistance state can be effectively maintained and power loss reduced.Anti-oxidation materials: The welding materials or connection materials used in Copper-Aluminum Terminal usually have good anti-oxidation properties, ensuring that the connection points will not increase resistance due to oxidation during long-term use.4. Mechanical strength and stabilityHigh mechanical strength: Copper-Aluminum Terminal is designed with mechanical strength and stability in mind to ensure that the connection will not loosen or fall off during long-term use and vibration environments. Mechanically stable and high-strength connections maintain low resistance and reduce power loss due to poor contact.Thermal expansion coefficient matching: Copper-Aluminum Terminal takes into account the difference in thermal expansion coefficients of the two materials during the design and manufacturing process. Through appropriate structural design and material selection, it is ensured that the connection point can remain stable when the temperature changes, and the resistance will not increase due to thermal expansion mismatch.5. Low temperature rise designHeat dissipation design: The connection point design of Copper-Aluminum Terminal usually takes heat dissipation into consideration. Through reasonable heat dissipation structures, such as adding heat sinks and using thermally conductive materials, the heat accumulation at the connection points and temperature rise can be reduced, thereby reducing the increase in resistance and power loss caused by temperature rise.Temperature rise monitoring: Some high-end Copper-Aluminum Terminal systems are equipped with a temperature rise monitoring function to monitor the temperature of the connection point in real time, detect and handle abnormal high temperatures in a timely manner, and ensure the low resistance and low power loss status of the connection point.6. Reliable connection technologyUltrasonic welding: Copper-Aluminum Terminal often uses ultrasonic welding technology, which can achieve a strong connection between copper and aluminum without using solder. Ultrasonic welding ensures low resistance and high mechanical strength, reducing power loss at the connection.Cold-pressed connection: Cold-pressed connection technology uses mechanical pressure to press the Copper-Aluminum Terminal together to form a low-resistance connection. This connection method does not require high-temperature welding and avoids the problems of oxidation and increased resistance caused by welding.Copper-Aluminum Terminal effectively reduces power loss in electrical connections by taking advantage of copper and aluminum's high conductivity, low resistance design, corrosion resistance, mechanical strength and stability, low temperature rise design, and reliable connection technology. These features and designs ensure that Copper-Aluminum Terminal can provide stable, low-loss electrical connections in various application scenarios, meeting high performance and high reliability requirements.
