stackable lugs with interlocking, anti-rotation mechanism applications: multiple terminations on a singular stud in a high vibration environment such as: starter motors on diesel engines and electrical motors on compressors or pumps customer concern: a manufacturer of industrial trucks needed to improve the long-term reliability of electrical components. a typical application includes multiple lugs stacked on a single stud. the inherent vibration caused the multiple stacked lugs to rotate and become loose, which created poor electrical connections resulting in failures, electrical shorts and warranty claims. panduit solution: stackable lugs with interlocking, anti-rotation mechanism panduit developed a tubular terminal with an interlocking mechanism that allows the terminals to be stacked and oriented in 45 increments. when a fastener is tightened down on the stud, the assembly securely locks together preventing rotation of the parts. in-house reliability testing verified the enhanced performance of the anti-rotation feature. stackable lugs use the same barrel dimensions as standard parts and do not require special crimp tooling. application considerations: consult factory to determine if the stackable feature is available for your current size of lug. ensure that interlocking anti-rotation mechanisms between lugs are fully engaged before securing the fastening nut. these lugs can be used in non-stacking applications and are interchangeable with lugs that do not have the interlocking anti-rotation feature. stackable lugs showing top and bottom features of interlocking, anti-rotation mechanism three stackable lugs fastened to a bolt in different orientations
