ABSTRACT:
This invention provides an improved cable clamp construction for telecommunication cables such as coaxial cables made from continuous filaments of optical glass fibers which are surrounded by an annulus of aramid material and contained within an outer plastic jacket. In order to provide intermediate gripping action on the continuous cable without its interruption, the gripping action must be carefully controlled and distributed over a relatively sizable intermediate area of the cable to prevent damage to the fragile fibers of the cable over a long useful life in varying climatic conditions. The gripping clamp is comprised of a limited number of components which are capable of surrounding and gripping the cable without undue flexure, the clamp being comprised essentially of a separable sleeve member and a separable plug member, both of which have tapered surfaces to positively secure the cable with compressive forces over a localized area. The complementarily tapered components of the sleeve and plug permit an increased gripping action on the cable without damage thereto for maintaining the cable in permanent tension between a pair of supporting points with an un-tensioned intermediate area of the cable retained between an adjacent pair of supporting points. The separable sleeve and plug members of the clamp firmly grip the cable, in distributed compression greater than the amount of tension.
