Why Do Parallel Grooved Wire Clamps Perform Poorly In Environments With Strong Vibration?

As a common wire connection device, the parallel groove clamp mainly relies on bolts and metal clips to fix two wires. In static or slightly mechanically disturbed scenarios, this design can serve a basic connection function, but in continuous and severe vibration environments, the parallel groove connector will face a significant risk of performance degradation.

Vibration causes repetitive loads on the fasteners in aluminium pg clamp. Unlike instantaneous impacts, these repetitive loads do not easily dissipate but continuously apply to the bolt preload, gradually weakening the friction at the connection point. bimetal pg clamp Under continuous vibration, the contact state between the fastener and the wire will change slightly, which will cause the contact surface to move relative to each other. Over time, this tendency for fretting can cause loosening within blackburn parallel groove clamp and even fluctuations in contact resistance, introducing instability into circuit operation.
