US 6,135,398 A · Trunion clamp for optical fiber

Abstract

An easily installable, robust device capable of securing and supporting cable even under extreme weather and loading conditions. The device supports cable during and after stringing of the cable. The device is easily adaptable to accommodate a large range of cable diameters and can be mounted to a variety of support structures. The device includes a body and cap formed via die casting. A non-machined hinge mechanism that is die cast as a portion of both the body and the cap connects the same and allows the device to be mounted as a single unit to a support structure. A two piece grooved elastomer bushing seats in the body and cap to surround and cushion the cable extending through the device. By altering the size of the grooves of the bushing, various diameter cable can be accommodated. Side walls having windows formed on the body of the trunion help facilitate distribution of the load of the cable. The tunion body also includes a non-threaded hole that may be used in conjunction with a fastener such as a lag bolt or a double arming bolt to secure the trunion to a support structure.

Dependent claims

A cable support device for supporting a fiber optic cable comprising:

a body having an inner grooved surface defining a body groove extending longitudinally from a first end to an opposite end of said body;
a cap having an inner grooved surface defining a cap groove extending longitudinally from a first end to an opposite end of said cap;
a hinge mechanism for connecting and aligning said body and said cap prior to stringing said cable such that said body groove and said cap groove define a channel through which the cable extends, said hinge mechanism comprising a hinge integrally formed as part of said cap and a bracket integrally formed as part of said body;
a body bushing having an outer surface and an inner grooved surface, said outer surface configured to seat within said body groove;
and
a cap bushing having an outer surface and an inner grooved surface, said outer surface configured to seat within said cap groove such that when said body and cap are aligned and connected, said body bushing and said cap bushing define a channel for receiving the cable, wherein said body bushing and said cap bushing are formed from molded elastomer material having a dielectric constant close to the dielectric constant of said cable.
