Definitions

  • the present invention relates to an improved cable clamp, which can be used to terminate a cable, for example to a bus bar. It is known to provide cable clamps comprising a male jaw having a tail and an integral part-cylindrical head, and a female jaw having a tail and an integral yoke which defines a part-cylindrical socket, the head of the male jaw being received in the socket to permit relative pivotal movement between the jaws, a cable receiving opening extending diametrically through the head and a cable receiving opening extending radially through the yoke, the said openings being aligned in an open pivotal position of the jaws to permit insertion of the cable therethrough and substantially misaligned in a closed pivotal position of the jaws to clamp the cable, the tails being clamped together to hold the jaws in the closed position.
  • the cable clamps of this form shown in Cornell U.S. Patents 4,357,068, 4,479,694, 4,548,462 and 4,898,551 have been found to provide excellent operational characteristics. They can be easily installed without special tools; they provide high cable pull-out resistance and low electric resistance; and it may be arranged that the inner part of the clamp can be assembled into the outer part of the clamp in two separate orientations, each adapted to terminate a particular diameter cable.
  • clamps of this type are increasingly popular.
  • One high volume application for such clamps is at the point where power is taken from power transmission lines.
  • Such connections are usually made at the top of transmission poles with the clamp in a vertical orientation and the cable leaving the clamp vertically downwards.
  • This orientation presents problems, especially in outdoor situations, of moisture entering the upwardly pointing cable and penetrating inside the insulation. Such moisture penetration can cause electrical problems with the cables.
  • One object of the present invention therefore is to provide a cable clamp in which the cable may be protected from moisture penetration as described above.
  • the present invention provides a cable clamp having a first end, a second end, and a longitudinal axis extending therebetween, comprising a clamping structure adjacent said first end adapted to clamp the end of a cable, an attachment structure adjacent said second end adapted to permit attachment of said clamp to an external surface, characterized by further comprising a shield member between said clamping structure and said attachment structure, said shield member having a circumference defining a sealing surface positioned radially outwardly with respect to the attachment structure whereby in use to enable the clamping structure to be provided with a cover sealed to the sealing surface of said shield member to inhibit moisture penetration into a clamped cable.
  • the cover should ideally also extend over the end of the remaining insulation on the clamped cable.
  • a cable clamp as described in the preceding paragraph is used to clamp a cable, and then a moisture resistant cover is applied to the cable and the cable clamp so that the cover seals to the cable on one side of the clamping structure and to the shield number on the other side of the clamping structure.
  • the first jaw is positioned within the cover, and the cover resists moisture penetration into the clamped cable.
  • a fastener is provided to clamp the tails together to clamp the cable.
  • This is generally a nut and bolt assembly passing through holes in the tails. Therefore the profile of the clamps is increased by a bolt head on one side of the clamp and a nut on the other.
  • the fastener comprises a threaded hole in one of the tails, an unthreaded hole in the other tail which aligns with the threaded hole, and a bolt.
  • the clamping of the tails is achieved by passing the bolt through the unthreaded hole and engaging it in the threaded hole.
  • the threaded hole extends through a protruding boss, over which the unthreaded hole fits.
  • this arrangement provides the additional advantage that a shorter bolt may be used to clamp the tails together, which ensures that the end of the bolt does not protrude through the clamped tails.
  • Fig. 1 shows a perspective view of a cable clamp 10 which incorporates a presently preferred embodiment of this invention.
  • the cable clamp 10 includes a male jaw or clamping member 12 and a female jaw or clamping member 14.
  • the male jaw 12 is shown in greater detail in Figs. 3 and 3a, and it includes a cylindrical head 16 which defines a cylindrical surface 18 centered on a cylinder axis 2C (Fig. 1).
  • a first tail 22 extends radially away from the head 16, and the male jaw 12 is symmetrical about a plane of symmetry 24 (Fig. 3) which contains the cylinder axis 20.
  • the male jaw 12 includes a first cable receiving opening 26 that, as shown in Fig. 3, is oriented at a skew angle A with respect to the first tail 22 and the plane of symmetry 24.
  • the cable receiving opening 26 is adapted to receive the terminal portion of a cable, and the opening 26 opens out at both sides of the first tail 22 at a window 28 which passes completely through the tail 22.
  • the tail 22 defines a free end 30 and a pair of spaced, parallel, opposed first surfaces 32 adjacent the free end 30. Both of these first surfaces 32 are parallel to the plane of symmetry 24.
  • a fastener receiving opening 34 extends completely through the first tail 22 and receives a mounting fastener as described below.
  • Figs. 1, 2 and 2a provide a detailed illustration of the female jaw or clamping member 14, which includes a head receiving portion or yoke 36 which is generally C-shaped and defines a part-cylindrical socket 37 sized to receive the cylindrical head 16 for rotation about the cylinder axis 20.
  • the yoke 36 is integrally connected with a second tail 38 that includes a projection 40 positioned to extend into the window 28 when the first and second tails 22, 38 are clamped together.
  • a second cable receiving opening 42 extends through the yoke 36 and is positioned to align with the opening 26 when the jaws are in an open position, in which the first and second tails 22, 38 are separated from one another.
  • the second tail 38 defines an intermediate portion 44, an end portion 45 and two opposed parallel second surfaces 46.
  • a threaded boss or key 48 is fixed in an opening 51 passing through the intermediate portion 44 of the second tail 38 and is aligned with the opening 34 when the first and second tails 22, 38 are clamped together, such that the opening 34 fits over the upstanding part of the boss 48.
  • Figs. 4 and 5 show the manner in which the cable clamp 10 can be arranged to clamp a cable by a fastener 52.
  • the fastener 52 clamps the first and second tails 22, 38 together.
  • the fastener 52 is initially removed and the male jaw 12 is rotated to an open position (not shown) in which the first and second tails 22, 38 are spaced one from another. Then the terminal portion 54 of a cable is inserted through the cable receiving openings 26, 42 until it abuts against the extreme end of the window 28. Then the male jaw 12 is rotated toward the closed position shown in Figs. 4 and 5, and the fastener 52 is used to clamp the first and second tails 22, 38 together. This causes the projection 40 to enter the window 28 and the cable to be clamped at four clamping points as shown by the arrows in Fig. 4. In this way the male jaw 12 and adjacent portions of the female jaw 14 cooperate to form a cable clamping structure.
  • the jaws 12, 14 can be assembled in two different orientations to clamp cables of two different diameters.
  • the male jaw 12 is in a first orientation in which the angle B separates the open and closed positions.
  • the male jaw 12 has been rotated by 180° about an axis of symmetry that is contained in the plane of symmetry 24 and is perpendicular to the cylinder axis 20. Because of the skew angle A shown in Fig. 3, in this alternate position the angular separation between the open and closed positions of the male jaw 12 is B + 2A, and thus the cable clamp 12 when assembled as shown in Fig. 5 operates to clamp a smaller cable.
  • the cable clamp 10 functions in similar manner to the cable clamp described in detail in the above-identified Cornell patents.
  • the fastener 52 is in the form of a bolt 52 which passes through opening 34 in the tail 22 of the male jaw to engage with the threaded hole of the boss 48.
  • a washer 53 may be included if necessary or desirable.
  • bolt 52 should not protrude through the boss 48 in order to minimize the end-on profile of the assembled clamp.
  • the tails of the clamp must be closed, by some external force, sufficiently that a bolt positioned through opening 34 will reach and engage the thread of the opening through the other tail. After such engagement the clamp is closed further by tightening of the bolt.
  • the clamp does not have to be closed as much as it would be in the absence of the upstanding boss 48 before the bolt engages the thread, for a given length of bolt.
  • a shorter bolt can be used to close the clamp fully.
  • a bolt can be used which does not protrude through the clamped tails, even when the clamp is fully closed.
  • the preferred arrangement is to provide a boss 48 which protrudes above the surface of tail 38 by an amount approximately equal to, but slightly less than, the thickness of the tail 22, and to use a bolt having a length approximately equal to the combined thickness of the two tails.
  • the clamp may be attached to a support element such as a bus bar either before or after the cable is clamped as described above.
  • This attachment is preferably by way of an opening 47 in the end portion 45 of the second tail 38.
  • the opening 47 is aligned with a corresponding opening in the support element (not shown), and a nut and bolt assembly (not shown) is passed through the openings to secure the clamp.
  • the end portion 45 of the second tail 38 including the opening 47 forms an attachment structure.
  • either one of the openings may be threaded and attachment of the clamp can be by way of a single bolt in a manner similar to that described above for the clamping of the tails.
  • the shield member of the present invention is embodied in the clamp 10 by a planar member 49.
  • the shield member 49 is positioned above the clamping arrangement and the clamped cable.
  • the shield member 49 has a rounded profile and has a profile which generally coincides with the end-on profile of the rest of the clamp.
  • Fig. 6 illustrates the shield member 49 according to this preferred embodiment.
  • Shield member 49 is planar and has a rounded circumference 56 which forms a sealing surface and defines a profile which generally coincides with the end-on profile of the rest of the clamp.
  • Shield member 49 is also provided with a slot 55, which enables the shield member 49 to be slid over the end portion 45 of the tail 38 to the position shown in Figs. 1 and 2.
  • the edges of the slot 55 are preferably sealed to the tail 44 to prevent moisture penetration through the slot 55.
  • This seal is preferably formed by the use of a waterproof adhesive, such as an anaerobic engineering adhesive, which is impervious to moisture and of high strength.
  • the adhesive manufactured by the LocTite Company and identified as product number 648 has been found suitable.
  • the tail 44 may be provided with a protrusion or rib (not shown) against which the shield member 49 abuts when in position in order to facilitate positioning of the shield member to avoid interference with the operation of the clamp.
  • the shield member 49 is preferably sufficiently rigid to retain its shape when the waterproof cover is applied to the clamp.
  • the coefficient of thermal expansion of the shield member 49 is preferably matched to that of the tail 44 to reduce stress on the seal between the tail 44 and the shield member 49. This can be accomplished by forming the shield member 49 of the same conductive alloy as the tail 44.
  • the shield member 49 may have a thickness of 10 mm and a circumference substantially equal to the maximum circumference of the clamping arrangement.
  • the shield member 49 is preferably convex and smoothly rounded to enhance sealing with the waterproof cover. The illustrated embodiment retains its shape under the forces applied by the cover.
  • the end-on profile of the shield need not be exactly the same as that of the clamping arrangement. It is preferred that the profile of the shield should be rounded, which facilitates the sealing of the cover. Also the overall size of the shield may be different from that of the end-on profile of the clamping means, in particular it may be smaller, and still allow a cover to be applied forming a generally tubular unit.
  • the clamp In order to facilitate the use of the clamp in as many situations as possible it is preferably made as compact as possible. In particular the area of the end-on profile and the shield should be minimized as this affects the size of the final generally tubular sealed unit. In some applications there are standards for the size of the clamps which must also be met. Accordingly this invention is preferably incorporated into clamps having a small head profile. Also the profile can be reduced by the use of the fastener as discussed above.
  • Fig. 7 is a sketch illustrating the installation of the clamp 10 in a cover 60.
  • the only parts of the clamp 10 visible once the cover 60 is installed are the end portion 45 of the female jaw with the opening 47 to allow mounting of the clamp 10.
  • the cover 60 covers all the other parts of the clamp 10 and also extends over a length of the cable 61, thereby providing protection from moisture ingress for the clamped end of the cable.
  • the cover illustrated is a typical type of cover which may be used with this invention, having known electrical stress relieving discs around it.
  • the clamp of the present invention is particularly constructed to be usable with standard covers for this type of installation.
  • the invention may be used with heat shrink tubes, cold shrink tubes or with self-amalgamating tape wound around the clamp.
  • Figs. 8 and 9 show two steps in applying a second waterproof cover 60' to the clamp 10.
  • the clamp 10 is applied to the cable, using the bolt 52 to develop the required clamping force.
  • the cover 60' (an unrecovered length of heat shrink tube) is positioned as shown in Fig. 8 around a portion of the cable, the clamping arrangement, and the shield member 49.
  • the cover 60' is then shrunk in place in the conventional manner, as for example by applying heat or removing an expanding sleeve.
  • This causes the cover 60' to conform to the clamp 10 as shown in Fig. 9, and to form a moisture resistant seal against the sealing surface at the perimeter of the shield member 49 and at the cable adjacent to the clamp 10.
  • the cover 60' may include on its inner surface a layer of sealing material to enhance formation of a moisture resistant seal with the shield member 49 and the cable.
  • the corners of the clamp in particular the female jaw member, may be rounded. This is illustrated in the preferred embodiment as indicated at numeral 62 of Fig. 2a.
  • the jaws 12, 14 are preferably machined from extruded bar stock.
  • the bar stock is preferably an aluminum alloy having an electrical conductivity of not less than 46% of the International Annealed Copper Standard and a tensile strength of approximately 300 MPa.
  • the cable receiving openings should preferably be sized approximately 110% of the largest cable to be clamped.
  • the opening 47 is separately machined into jaw 14, as is the threaded opening.
  • the threaded opening is provided by first machining a second opening 51 of approximately the same size as the opening 47 and inserting and fixing the boss 48 into the second opening.
  • the boss 48 may be of a different material, metal or alloy to that used for the jaws.
  • the threaded opening may also be provided by machining a boss and a threaded hole directly in the material of jaw 14, as is presently preferred.
  • the invention is not limited to the described embodiment.
  • the means for mounting the clamp to another surface and the shield member may be provided on the tail of the male jaw member.
  • the threaded hole and/or boss for the first fastening means may be provided in the tail of the male jaw member.
  • the act of clamping the cable clamp to the end of the cable is separated from the act of attaching the clamp to the required bus bar or the like.
  • the opening 47 allows the clamp 10 to be bolted to a bus bar after the waterproof cover has been applied, and the opening 47 is physically separated from the fastener 52, which is inside the waterproof covering.
  • the clamp may be attached to the end of the cable and the waterproof cover applied to the clamp, for instance by shrink wrapping, at any time and position and before the attachment to the bus bar or the like is made.
  • the attachment to the bus bar is therefore facilitated because the installer effectively has a cable with a bolt hole at the end which simply requires attaching as required.
  • the alignment of the cable with the clamp and the application of the cover can be performed away from the actual place of installation, and need not be performed in relatively inaccessible places.
  • the boss 48 allows the clamp to be closed in many applications with a short bolt 52. In this way the need for special installation tools, such as hydraulic equipment or ratchet wrenches for determining bolt tightness, is reduced or eliminated. These clamps can therefore be easily installed on cables in difficult settings, such as on utility poles.
