Abstract: The present invention presents an improved clip and an improved block wherein the material requirements for the clip are reduced and transmission performance for the assembly is improved. The present invention also presents a method of manufacturing the improved clip. The clips are of the type generally referred to in the art as 66 type clips. The clip of this invention has an oval opening with parallel sides between the base and that portion of the clip which holds the wire; and the oval aperture is flanked by arm portions of diverging width from the top of the aperture to the bottom of the aperture. In other words, the sides of the arms adjacent to the aperture are parallel, and the sides of the arms remote from the aperture diverge outwardly. This makes the arms thicker in width as they approach and join the base. This construction achieves the important advantage of a tapered beam element, which is well known to result in superior stress distribution than beams whose thickness is uniform.

Abstract: A device for connecting to the end of a cable, having stranded wires including a sleeve nut. The sleeve nut has threads at one end. The cable is placed through the sleeve nut with the threads facing towards the end of the cable. A sleeve is provided with gripping means. The cable is placed through the sleeve after the sleeve nut. The gripping means are in contact with the outer insulated surface of the cable and prevent the cable from sliding out of the sleeve. An outer support ring having threads and including a pointed contact is provided. The pointed contact penetrates the stranded wires of the cable as the sleeve nut threads and the outer support ring threads engage and are rotated. This causes the sleeve nut and the outer support ring to move together, radially compressing the sleeve, so that the gripping means prevent the cable from sliding out of the sleeve.

Abstract: A method for terminating an electrical conductor, comprises an outset step of defining a housing having an open end and a closed end and at least one passage therethrough for entry of the conductor into the housing to permit a termination end of the conductor to be resident interiorly in the housing. Next, the housing passage is closed and the housing is disposed with the housing open end vertically above the housing closed end. With the housing so disposed, sealant gel is introduced in liquid state interiorly of the housing. While the sealant gel is in the liquid state, there is secured with the housing, through the housing open end, apparatus for subsequent use in terminating the conductor, Upon transition of the sealant gel to a cured state, the housing passage is opened. To complete the conductor terminating method, at the installation site, the conductor is inserted into the housing passage and into registry with the terminating apparatus.
