  • Strain relief for armored cable
    Patent number: 9720198
    Abstract: A strain relief device for armored fiber optic cable is described. The strain relief device can made up of a boot collet and a collet nut. The boot collet can have a collet, flexible boot, boot collet threads, and a camming surface. The collet nut can have collet nut threads and a collet nut slope. The strain relief device operates by having the camming surface engage the collet nut slope, causing the collet to compress onto the armor sheath when the boot collet threads engage the collet nut threads as the collet nut is tightened onto the boot collet.
