Definitions

  • the present invention relates to a securing component for a rotationally fixed electrical connection of a cable, such as a high voltage jumper cable, comprising a coupling designed to be linked with a first terminal end of the connection in a rotationally fixed manner.
  • the present invention further relates to a terminal end for a rotationally fixed electrical connection of a cable, such as a high voltage jumper cable, having a terminal body comprising a coupling element designed to be electrically and mechanically coupled with a first terminal end of the connection.
  • a cable such as a high voltage jumper cable
  • the present invention relates to a kit for a rotationally fixed electrical connection, such as a high voltage jumper cable, comprising a terminal end of the connection designed to be electrically connected with a first terminal end of the connection.
  • the present invention relates to an electrical connection assembly for a rotationally fixed electrical connection of a cable, such as a high voltage jumper cable, comprising a first terminal end of the connection and a terminal end of the connection that is electrically connected with the first terminal end.
  • a cable such as a high voltage jumper cable
  • Jumper cables are used for example between the locomotive, rail-road cars and cab cars for multiple-unit train control and the transmission of high voltage electricity.
  • a further application of jumper cables is the electrical connection between an automobile or a road tractor with a trailer.
  • jumper cables electrically connect two coupled, however individually moveable, units and are thus exposed to rigorous forces acting on the cable connection.
  • jumper cables are provided with a terminal end designed as a termination lug, which is placed on a bolt or rod of the other terminal end of the connection. By screwing a nut on the bolt, the cable connection is secured. Uncontrolled rotation of the termination lug may lead to a loosening of the nut and an interruption of the electrical connection.
  • the termination lug of the cables can be designed with flat parts that may sit on corresponding flat sides of the bolt at the other terminal end. The corresponding flats avoid rotation of the lug around the bolt.
  • the termination lug of the cable needs to be specifically designed with flat parts.
  • the direction of the flat parts of the lug defines the angular arrangement of the termination lug with respect to the other terminal end. So, it is necessary to have available many different kinds of lugs and kinds of jumper cables in order to be able to establish the electrical connection of a cable at a specific angle of rotation between the termination lug of the cable and the other terminal end of the electrical connection to meet specific projection requirements of the cable.
  • the securing component of the present invention solves this problem by comprising a fixation member capable of securing a terminal end of the connection at various angles of rotation in relation to the securing component.
  • the terminal end of the initially mentioned type according to the present invention solves the above technical problem by a terminal body comprising a mounting organ for securing the terminal body at a desired angle of rotation in relation to a first terminal end of the connection, wherein the mounting organ is spaced apart from the coupling element.
  • the terminal body of the inventive terminal end can be connected at various different angles of rotation. Since the mounting organ is spaced apart from the coupling element, there is no constraint to be able to mount the terminal end only at one specific angle of rotation. Using the terminal end according to the present invention thus allows to secure the terminal body at various different angles of rotation in relation to the first terminal end of the connection.
  • the kit of the initially mentioned type as well as the electrical connection assembly of the originally mentioned type solve the above-mentioned problem by comprising a securing component according to the present invention.
  • the coupling of the securing component is linked with the first terminal in a rotationally fixed manner, and the fixation member secures the second terminal end at a selected angle of rotation, i.e. selected from the various predetermined angles of rotation, in relation to the first terminal end.
  • the inventive securing component can be linked with the first terminal end of the connection in a rotationally fixed manner via its coupling.
  • "Rotationally fixed”/"rotationally fixed manner” in the sense of the present application means that the two link components, such as the securing component and the first terminal, cannot be rotated with respect to each other around a rotational axis (also referred to as axis of rotation).
  • the rotational axis is the axis around which a cable, such as a jumper cable, tends to rotate.
  • the longitudinal axis of the rod corresponds to the axis of rotation.
  • the fixation members of the securing component allow to secure the other terminal end of the connection, for example the cable terminal end, such as a termination lug, at various predetermined angles of rotation in relation to the securing component.
  • the cable terminal end such as a termination lug
  • This way, different kinds of lugs and jumper cables can be avoided, leading to a reduction in material required, reduction of development time, simplifying manufacturing and installation processes and hence cost reduction.
  • the "angle of rotation” is a distinct angle, with respect to the rotational axis, at which the two terminal ends of the electrical connection are electrically and mechanically coupled in a rotationally fixed manner with each other.
  • the angle of rotation might be compared to the position of the pointer on the clock, the termination rod being the centre of the clock.
  • Various angles of rotation means that the terminal end of the connection may be secured on the fixation member at a minimum of two, preferably three or more, different angles of rotation.
  • the different predetermined angles of rotation may lie in the range of 0°to 360°, for example 0° to 180°, or any arbitrary interval therebetween.
  • the securing component of the present invention may be a washer comprising the coupling and the fixation member.
  • a washed can be easily mass-produced, for example from stamping from a sheet of metal, and is easily designed as required and provided with the coupling and the fixation member.
  • the securing component of the present invention has a coupling comprising a fitting profile shaped to interlock with the first terminal end rotationally fixed.
  • a fitting profile for example a specific contour or a pin, latch, catch, protrusion or recess, is easy to manufacture and design corresponding to a complementary counterpart on the first terminal end of the electrical connection.
  • the fitting profile may be designed as a profiled hole, which is easy to manufacture yet capable of efficiently interlocking with the first terminal end rotationally fixed.
  • the profiled hole of the coupling from the securing component may be a through-hole with a circular border, whose circularity is disrupted by flat sections, which can be coupled with the termination flats of a termination rod being the first terminal end.
  • the fixation member of the securing component may comprise an array of fixation elements arranged in a predefined pattern.
  • each fixation element corresponds to a specific angle of rotation.
  • An easy way to achieve this is to arrange the different fixation elements of the array in a curved pattern, for example a curve pattern corresponding to a circular path having the axis of rotation in its centre, wherein the distance from the centre to each fixation element on the circular path is always the same.
  • the distance between adjacent fixation elements in the array of the fixation elements may be constant. This allows for a regular series of predetermined angles of rotation provided by the fixation members.
  • the different angles of rotation may be equidistantly spaced apart from each other, for example by 5°, 10°, 15°, or an arbitrary degree between 1° and 120°.
  • At least one of the fixation elements in the array is formed as a fixation recess and/or a fixation protrusion.
  • the recess may be formed for example as a hole, such as a through-hole, and the fixation protrusion may be designed as a pin or pall projecting out of the body of the securing component.
  • a series of holes is arranged in a predetermined pattern.
  • the securing component of the present invention may further comprise a guiding structure for routing the second terminal end along the various predetermined angles of rotation.
  • a guiding structure for example a curved guide rail or a curved guide groove that may be concentrically arranged around the axis of rotation, facilitates selecting one of the various predetermined angles of rotation.
  • the fixation member is arranged adjacent to or is arranged on the guiding structure.
  • This proximity/conformity of the fixation member and the guiding structure allows for a very compact design of the securing component, while at the same time having the advantage of easily reaching the selected angle of rotation from the various predetermined angles of rotation at the fixation member.
  • the securing component may comprise a guide rail with various protrusions and/or recesses in the rail.
  • the mounting organ comprises an anchorage recess or anchorage protrusion.
  • the terminal end of the present invention may comprise a lead structure for moving the mounting organ to the desired angle of rotation. This facilitates the arrangement of the terminal end at the desired angle of rotation with respect to the first terminal end, such as a terminal rod.
  • the lead structure may comprise a lead groove and/or a lead rail.
  • the lead structure of the terminal end may be complementary to the guiding structure of the securing component. This way, the guiding structure of the securing component and the lead structure of the terminal end may constitute a guidance defining the rotational movement of the terminal end with respect to the securing component.
  • the terminal end may be a terminal end according to the present invention.
  • the mounting organ of the terminal end may be complementary to the fixation member, preferably the fixation elements from the array of fixation elements.
  • the terminal end may be provided with an anchorage recess as a mounting organ and the securing component may comprise an array of fixation protrusions which may be inserted into the anchorage recess for a rotationally fixed connection at a specific angle of rotation.
  • the mounting organ may comprise an anchorage protrusion and the fixation member of the securing component may comprise an array of fixation recesses arranged in a defined pattern, into which the anchorage protrusion may be inserted.

  • Said termination rod comprises a coupling section 8 having a substantially circular cross-section, however with two flats 9.
  • the two flats 9 are arranged opposite to the coupling section with respect to the longitudinal axis L of the termination rod 7.

  • a nut 16 is screwed on the distal section 14 of the termination rod 7.
  • An electrical connection 3 of a cable 1, such as a high voltage jumper cable as depicted in Fig. 1 has to sustain the rigors of the high voltage rail environment.
  • One problem of such electrical connection 3 is that uncontrolled rotations of the termination lug 5 around a rotation axis R, which coincides with the longitudinal direction L of the termination rod 7, are to be avoided because such uncontrolled rotations may lead to the loosening of the nut 16 and the interruption of the electrical connection 3.

  • the fixation elements are designed as fixation recesses 26 to 26j in the third embodiment of the securing component 10 as well.
  • the fixation recesses to 26 to 26j are designed in areas of the body 19 of the securing component 10, having an improved thickness, so the holes of the recesses 26 to 26j can be made longer providing an improved stability of the securing component 10 as well as an electrical connection assembly 17 comprising said component 10.
  • the array of fixation elements 25 to 25j in the third embodiment comprises more elements, namely a total of 11 fixation elements 25 to 25j, compared to the five fixation elements 25 to 25d of the first embodiment.
  • the array of fixation elements 25 to 25j according to the securing component 10 of the third embodiment thus spans more of the circumference of the disc-shaped body 19, allowing to secure the terminal end 4 at more possible angles of rotation ⁇ in relation to the securing component 10.
  • the individual fixation elements 25 to 25j are at constant distance between adjacent fixation elements.
  • the securing component 10 of the third embodiment even though not essential, further comprises a guiding structure 27.
  • the securing component 10 may route the terminal end 4 along the various different angles of rotation, at which the terminal end 4 may be secured in relation to the securing component 10 using the fixation member 24.
  • the guiding structure 27 is designed as a guide rail 31 projecting from the front side 28 of the disc-shaped body 19 of the securing washer 18.
  • the guide rail 31 stands up from the front side 28 close to the outer edge 29 of the disc-shaped body 19.
  • One face of the guiding structure 29 is forming a slide face 30, which serves as a guidance for routing the terminal end 4 along the fixation member 24.
  • the guide rail 31 is formed in that area of the securing component 10 where the fixation member 24 with its array of fixation elements 25 to 25j is designed.
  • the fixation recesses 26 to 26j are holes extending through the guide rail 31 in a direction parallel to the rotational axis R.
  • the fixation member 24 is arranged on the guiding structure 27, which facilitates to direct the terminal end 4 to a specific fixation element 25 to 25j from their array of fixation members, in order to select a specific angle of rotation ⁇ , under which the terminal end 4 is to be secured in relation to the securing component 10.
