摘要
介绍铝线在汽车蓄电池线中应用时解决电偶腐蚀、保证其拉脱力和压接电阻、提高铝强度的方法。通过摩擦焊接、超声波焊接或铜端子压接端表面蒸发镀铝的方法可以防止铜铝接触电偶腐蚀的发生。通过铝线与铜铝端子的四方双压接、六方双点压接能保证端子的拉脱力及压接电阻符合标准要求,铜铝端子铝内表面结构变化对压接电阻有一定的影响,铝合金代铝能够提高铝芯蓄电池线的强度。
The method of the anti-galvanic corrosion,crimping,and strengthening of the automobile aluminum storage battery harness is introduced.The friction welding,ultrasonic,and aluminum-plating can prevent the galvanic corrosion.The putout force and crimping resistance can meet the standard requirement employing the method of the square and double crimping,and hexagonal double crimping with two points.The structure of the inner surface of the copper aluminum terminal also affects the crimping resistance.The aluminum alloy can strengthen the automobile aluminum storage battery harness.
