ABSTRACT:
Fittings are provided for use in terminating parallel yarn ropes containing one or more electrical conductors, and methods are disclosed for securing the fittings to the ropes to afford separation of the conductors from the rope and connection to electrical apparatus. One fitting has a frusto-conical body portion providing a tapered peripheral surface with an axial bore and a bail extending beyond the base of the body. The rope yarns are inserted into the bore at the narrow end of the fitting and divided into two pairs of bundles with each pair being splayed outward diametrically of the bore and returned along the outside of the fitting for wrapping helically in opposite directions for a predetermined distance about the periphery of the rope. The ends of the bundles are secured to the rope, so that when tension is applied between the bail and the rope, the wrapped bundles grip the outside of the rope to mount the fitting securely to the rope. In an alternate embodiment, the fitting includes a thimble having a narrow end located adjacent the end of the rope, and the rope yarns are divided into two bundles which extend in opposite directions in the channel around the thimble and which are wrapped helically about the rope similarly to the first embodiment. Both fittings and a short section of the rope adjacent thereto are encapsulated by a mass of polyurethane which rigidifies and protects the termination.
