Abstract
A strain relief for distributing strain along an outer surface of an optical fiber cable is disclosed. The strain relief is shaped to surround and tangentially grip the cable via friction between the outer surface of the cable and an inner surface of the strain relief. The strain relief also includes a pulling eye to protect the cable (and a connector) from pulling force (i.e. strain), water and dust. The strain relief is relatively small, low cost and easy to use.
Claims15
An apparatus for distributing strain along an outer surface of an optical fiber cable comprising:
- a single-piece strain relief having an elongated slot along its entire length for receiving the cable and being shaped to surround and tangentially grip the cable via friction between the outer surface of the cable and an inner surface of the strain relief, wherein the shape of the strain relief is an S-curve, and wherein the strain relief attaches to a pulling eye and via a dust cap.
