K. PFIST'ERER Jan." 2 1934.
111115 SPAN CABLE GONNECTER FOR HIGH VOLTAGE LINES Filed Oct. 29. 192 9 Patented Jan. 2, 1934 UNITED STATES WIDE SPAN CABLE CONNEC'IER FOR HIGH- VOLTAGE LINES Karl Pfisterer, Stuttgart-Unterturkheim, Germany Application October 29, 1929, Serial No. 403,285, and in Germany April 3, 1929 The present invention relates to a wide span cable connecter for high-voltage lines.
Cable connecters, especially of the wide span type, must not only make good contact but possess also great tensile strength. To attain these objects slotted clamp sleeves are in general use which are spread apart by the pull of the cable and thus pressed against the wall of the connecter. In lines involving great tensile stresses electrolytic copper and the like, which otherwise would be excellent material, cannot be employed for the body, because the spreading pressure of the sleeve would break it. This constitutes a grave danger, especially in high-tension lines, the more so as the use of electrolytic copper for connecters, in which this spreading pressure does not take place, is out of the question owing to the working method to which it must be subjected.
The present inventioneliminates completely these drawbacks by emp oying a closed sleeve having only a very slight pitch up to 2 within the connecting body which is further provided with a corresponding hollow cone so that the wider opening is outside. When this sleeve is pressed firmly into the conical opening of the connecter body, which can be done by means of a nut screwed on outside, it cannot be pulled out even if great force be used, owing to its slight pitch, and it will not burst. Furthermore, the contact is much better than that made by slotted sleeves, as the entire circumference of the sleeve hugs the body of the connecter and serves as contact surface. Another feature of the connecter assembly constructed according to the present invention is that it can be mounted outside the body and the cable end with the sleeves slipped on need merely be introduced. This does not only facilitate fitting but makes it possible to convince oneself of the proper fitting of the parts without the usual windows.
It is further possible to employ electrolytic copper for the body of the connecter, because the inner cone can be made by a reamer and the other working methods unsuited for copper dispensed with.
One embodiment of the invention is illus- Figure 1 is a side view of the connecter; Fig. 2
a longitudinal section thereof; Fig. 3, a diagrammatic'view of acsleeve; and Fig. 4 is a cross section taken on line H of Fig. 2.
Referring to the drawing, the body member a of the connecter has the shape of a sleeve and is suitably made from electrolytic copper. To
6 in the opposite direction. Each cable end I: is
trated in the accompanying drawing, in whichsurrounded by a slotted sleeved which-is drawn in still more into the sleeve 0 by the pull of the cable b.
The body member a of the connecter is reamed conically corresponding to the cone of the sleeve 0 so that the wider opening is located outside. There are two conical internal surfaces each extending from the center thereof to the outer end and each surface being a slight conical surface.
To mount the connecter, an outer sleeve c is slipped over each cable end b and a slotted sleeve d pressed firmly into the sleeve 0 in the cable end which, with the sleeves c and d, is then introduced into the body a and pressed into the hollow cone of the body a by a nut e. Then mounting is finished.
I claim:-
1. A wide span cable connecter for high-voltage lines, comprising an integral outer body member having solid walls and a pair of slight and smooth conical internal surfaces, each conical surface extending from the center of the body to approximately the end thereof; a slotted sleeve mounted on each cable end and having an outer conical surface; an outer conical sleeve fitting over and cooperating with the slotted sleeve and having a slight external conical smooth surface cooperating with one of the conical surfaces of the outer body member; and means cooperating with each end of the body member to force the outer sleeve on the slotted sleeve and the latter to the cable and to engage the slight conical surfaces to thereby secure the -fitting over and cooperating with the slotted sleeve and having a slight external conical smooth surface cooperating with one of the conical surfaces of the outer body member; and a nut screwthreaded in each end of the body member to force the outer sleeve on the slotted sleeve and the latter to the cable and to engage the slight conic'al surfaces to thereby secure the ends of the cable in the connecter, the tension in the cable being carried by the body member and the sleeves around the ends fix each cable b within the body a, a totally enof the cable.
