Feb. 14, 1950 Filed July '15, 1945 J. L. KIELLAND CABLE CLAMP 2 Sheets-Sheet 2 Joh/AN L mi /sLLAM/J d TTORNEY Patented Feb. 14, 1950 CABLE CLAMP Johan L. Kielland, Montreal West, Quebec, Canada, assignor to The Shawinigan Water & Power Co., Montreal, Quebec, Canada, a corporation of Quebec Application July 13, 1945, Serial No. 604,901 In Canada. May 1, 1945 (i Claims.

This invention relates to cable connectors and more particularly to connectors for large electrical stranded conductors.

Large stranded conductors are commonly used for electrical circuits transmitting energy at high voltages or heavy currents. The effective joining and branching of these circuits presents mechanical and electrical problems due to the ductility of copper and, in particular, of aluminum, which metals are most commonly used as elecv trical conductors.

Existing types of compression clamps, where the metal of the clamp is forced under extreme pressure into the stranding so as to form one homogeneous continuous piece of metal, are, when correctly applied, highly effective connectors. For branch connections and parallel joints both the conventional T clamp and parallel groove clamps have been used. The tension on these connectors is applied by means of ordinary bolts and nuts.

These types of clamp were originally designed for copper rods and tubes, later for small copper and aluminum stranded conductors. As the need for connectors for larger and larger stranded cables became evident, the conventional design was simply enlarged upon with little thought of the characteristics of the large cable.

Accordingly, these clamp connectors have a number of disadvantages among which are the following:

(1) The outside diameter of the cable is progressively reduced with newly applied pressure.

(2) The cable is deformed transversely.

(3) It is necessary to tighten the clamps periodically in order to maintain effective contact pressure.

(4) The clamp becomes loose due to temperature changes.

It is a principal object of the present `invention to provide a cable clamp which does not have the disadvantages of prior clamps. It is a furtherobject of the invention to provide a clamp which has certain positive advantages as will become clear from the following.

Having regard to the foregoing, a preferred embodiment of my clamp includes a iiller adapted to lie between a pair of cables, a cover adapted to engage one of the cables, a spring support engaging the cover, a saddle adapted to engage the other cable and a spring acting between the support and the saddle whereby the cables are held under compression between the filler and the cover and the saddle respectively. An opening in the spring support accommodates a tapped shank on the saddle and a nut on the shank enables the saddle to be retracted against the action of the spring to facilitate the application of the clamp tothe cables.

The invention will now be further explained Figure l is a side elevation of a preferred connector of the parallel groove type.

Figure 2 is a vertical cross section partly in elevation along the line 2-2 of Figure 1.

Figure 3 is a. cross section, partly in elevation, of a connector of the T type.

Figure 4 is a cross section, partly in elevation, through an alternate form of parallel groove connector.

Referring more particularly to Figures 1 and 2 of the drawings, A and B represent the ends of two cables clamped together with the preferred clamp. Between the cables is a filler I I grooved as at IIa and IIb to provide elongated cableengaging surfaces. A cover member I5 extends over the top cable and is provided with a groove I5a presenting a surface engaging the cable A as indicated. The cover constitutes a xed jaw member. The cover includes projections I2 extending along each side thereof. Extending downwards from the cover is a support 2l)` substantially U-shaped in cross section and having at the upper edge of each side, projections 25 engaging the projections t2 of the cover. cover is provided with a hole I8 and each side of the support 20 with holes 22 adapted to register with the hole I8. A set screw 21 extends through the hole I8 and engages a tapped portion of one of the holes 22.

A head 3I grooved as at 3Ia to engage the cable B, and a set of downwardly extending Shanks 35 constitute a saddle. The head constitutes a movable jaw member.

through a hole 23 in the base of the support 20. A coil spring 4B encircles each shank 35 engaging the head 3| and the base of the support,v A nut 38 20 which constitutes a seat member. is screwed onto the threaded portion 31 and is adapted to work against the base of the support4 20 when it is desired to compress the spring. The sides of the support 20, which constitutes spaci ing means are provided with registering holes 24 into which an implement may be thrust to facilitate handling the clamp.

Before climbing the tower or the line,vtheY line-man assembles the two springs 40, the spring housing 2 0, the saddle 3l) and compresses the two after climbing to the points of installation, the line man lays the cover I5 over the line and slides the installation is complete.

The

The lower end., of each shank 35 is threaded as at 31 and extends The second i cable is then introduced and finally the illeiy-- The line-man then slackens the nuts 38, removes them, and z Any reduction in the diameter of the cable by the usual shrinkage is compensated for by the spring forcing the/cover I5 closer to the saddle l 3| so that the cables are always kept rmly clamped between the surfaces of the grooves |5a and lla, and 31a and lib.

The characteristic of the spring is such that it gives su'licient per-area pressure to secure current-carrying capacity without exceeding safe temperature limits. Under consideration of the shrinkage involved in the stranded cables, the length and strength of the springs are such that they always maintain necessary pressure to insure safe temperature limits.

The connector shown in Figure 3, is a T type clamp in which parts similar to those of vFigures 1 and 2 are employed in the run part, with the exception that only one cable C is clamped in this part. The parts are numbered similarly to Figures 1 and 2 with the exception that they are eachy one hundred higher. The tap part |15 can be any type of a conventional clamp, for instance of the compression type as shown. The operation of this clamp will be evident from the foregoing.

The type of clamp illustrated in Figure 4 is again a parallel groove type, but with a somewhat different housing assembly to that of Fig ures 1 and 2. The resilient spring 240 is compressed andthe housing parts 225 and 22|] kept together by separate bolts 250 and nuts 25|. It will be e'vident that the principle of maintaining floating pressure on the cables is the same as for the above-described designs. However, in order to obtain the necessary pressure on the cables, the bolts and nuts 250 and 25| must be tightened as no threaded Shanks and nuts (31 and 38 respectively, Figures 1 and 2) exist in this design.

The following are among the advantages of the invention. The connectors are quickly and easily installed. In the case of the types of connector illustrated in Figures l to 3, an installation can be checked by the foreman or superintendent from the ground merely by ascertaining that the two nuts are removed. The springs are powerful enough to maintain pressure between the cables sufliciently to transmit full cable current, and long enough to follow up any diminishing di ameters and changes due to temperature variations. The connectors have a modern appearance and improved Corona characteristics compared to conventional clamps. The parts of the connector are preferably made of strong highly conductive light metals, for instance aluminium, copper, magnesium or alloys. 4

It will be understood that, without departing from the spirit of the invention or the scope of the claims, various modications may be made in the specic expedients described.
