Abstract:
We disclose a device for preventing the intrusion of water or other liquids into the interior of an automatic splice. The device includes of a series of fingers that contact the cable stranding and wick water away from the cable and out of the connector. These fingers could be integrally molded into the cable cone or molded as a separate piece and inserted. They could also be constructed of any typical brush material such as metal, plastic, rubber, or fiber. The fingers could be arranged in a variety of configurations.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention is generally directed toward automatic tension splice connectors. More particularly, it is directed toward a nose cone for such an automatic tension splice connector that removes liquids from cables before it can damage the automatic splice. 
       BACKGROUND OF THE INVENTION 
       [0002]    Automatic splices are commonly used to connect suspended cables, such as overhead power lines, together. The lineman can simply push the cable into each end of the automatic splice, and serrated jaws on the interior of the automatic splice will hold the cable in place. Greater tension on the cable will result in increased holding force of the cable within the automatic splice. 
         [0003]    A common issue with automatic splices is failure due to corrosion caused by water travelling down the cable strands and entering the connector body. 
       SUMMARY OF THE INVENTION 
       [0004]    An object of this invention is to provide a device for removing water from a cable so as to prevent corrosion of the automatic splice. The disclosed device consists of fingers that come into contact with the cable and are capable of wicking water away from the cable so that it may drip away from the automatic splice.

     DETAILED DESCRIPTION 
       [0010]    The following detailed description is presented to enable any person skilled in the art to make and use the invention. For purposes of explanation, specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that these specific details are not required to practice the invention. Descriptions of specific applications are provided only as representative examples. Various modifications to the preferred embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the scope of the invention. The present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest possible scope consistent with the principles and features disclosed herein. 
         [0011]    Referring to the drawings,  FIG. 1 . illustrates an automatic splice  100  as found in the prior art. The automatic splice  100  typically has a tubular body  102  with openings  101  and  103  at either end for receiving a cable. The tubular body  102  is widest in the middle and tapers to its narrowest points at tubular body ends  110  and  112 . Funnel guides  132  are disposed at both tubular body ends,  110  and  112 . 
         [0012]    Funnel guides  132  initially receive the cable end and guide all strands of the cable toward the interior cavity of the automatic splice  100 . As the cable is pushed toward the center of the automatic splice, pilot cup  134  surrounds the end of the cable and guides the cable between serrated jaws  114  or  130 . 
         [0013]    Serrated jaws  114  and  130  can move freely within tubular body  102 , but are pushed toward ends  101  or  103  by means of compression springs  126  or  128 . The cable can be pushed toward center  124 , but when the cable is pulled toward openings  101  or  103 , serrated jaws  114  or  130  engage the cable firmly. The tapering of tubular body  102  causes serrated jaws  114  or  130  to tighten more firmly around the cable as more tension is applied to the cable away from the center of the tubular body  102 . 
         [0014]    In automatic splices of the prior art, water may enter the automatic splice  100  by running along the cable. The water would then typically begin to corrode the metal parts of the interior mechanisms of automatic splice  100 , such as compression springs  126  and  128 , or serrated jaws  114  and  130 . However, the disclosed invention can be used to remove water from the cable before it enters the interior of tubular body  100 . 
         [0015]    As will be appreciated from  FIGS. 2 ,  3 , and  4 , water drip nose cone  200 , consists of an outer casing  204  surrounding an interior space  206 . Fingers  202  extend from outer casing  204  into interior space  206 . The interior space  206  extends through the length of the outer casing  204  and is sufficiently large for a cable to pass through. The fingers  202  are configured to come into contact with strands of the cable when it is inserted through the water drip nose cone  200 . Fingers  202  will then wick away any water from the cable, resulting in the water dripping out of the outer casing  204  away from the automatic splice  100 . 
         [0016]    Outer casing  204  is configured to generally interface with the opening of automatic splice  100 . It consists of nose cone  210  and an end piece  212 . End piece  212  may be narrower than funnel guide  132  and may enter the opening  101  or  103  of the automatic splice when the cable is being inserted into the automatic splice  100 . Stop wall  208  prevents the nose cone  210  from being inserted into the automatic splice  100 . Alternatively, end piece  212  may be slightly larger than funnel guide  132 , such that the automatic splice  100  slides into end piece  212 . Nose cone  210  can be any shape, although preferably it is designed such that gravity will cause water to collect at the lowest point of the nose cone  210  and drip out of the lower edge. 
         [0017]    Fingers  202  may be constructed of a typical brush material, such as plastic, rubber, fiber, or metal. Fingers  202  serve two purposes: first, they may brush off any debris from the cable, and, second, they wick water liquids from the strands of the cable. It should be appreciated that in instances where fingers  202  are made of metal, the fingers  202  additionally serve to act as an inverted wire bristle brush that can remove corrosion. In such a configuration, as the cable is pushed through the water drip nose cone  200 , the metal fingers  202  will also scrape off any corrosion that may have already formed on the cable strand. Although shown to be arranged in rows in the figures, fingers  202  may be arranged in any pattern or arrays, including spirals or fully cover the interior of the outer casing  204 . 
         [0018]    In a preferred embodiment, the water drip nose cone  200  is made of injected, molded plastic. The fingers  202  may be integrally molded into water drip nose cone  200 , or the fingers may be constructed of at least one separate piece that is then inserted into the water drip nose cone  200 . 
         [0019]    In one embodiment, the water drip nose cone  200  may be a separate component from the automatic splice  100 . In such case, the cable would first be inserted fully through the water drip nose cone  200 , such that the leading tip of the cable is within or protrudes just beyond end piece  212 . The cable and water drip nose cone  200  will, then, be pushed against the automatic splice opening until the water drip nose cone  200  comes to a stop. The cable will be pushed along farther, causing it to slide through the water drip nose cone  200  and into the automatic splice  100 . 
         [0020]    In another embodiment, the fingers  202  may be incorporated directly into the automatic splice such that fingers  202  protrude from the funnel guides  132 . 
         [0021]    In another embodiment, the water drip nose cone  200  may also be designed for a retrofit application where the cable has already been inserted into automatic splice  100 . In such case, the water drip nose cone would be constructed as a clamshell design with outer casing  204  constructed in two halves. The two halves would be closed around the cable to form a complete water drip nose cone  200 . The water drip nose cone  200  would then be pushed against funnel guide  132 . 
         [0022]    The water drip nose cone  200 , is simple to use. The cable is first inserted fully through the water drip nose cone  200  before it is pushed into the automatic splice  100 . Any water or debris will be brushed off by the water drip nose cone  200 . Once in place, as any other liquid, flows down the cable toward the automatic splice  100 , the fingers  202  will wick away the liquid from the cable and draw it toward the outer casing  204 . The water will collect at the bottom of the outer casing  204  and then will drip out of the lower edge of it.
