Definitions

  • the present invention relates generally to the connection and disconnection of high voltage electrical connector elements in the field and pertains, more specifically, to an assembly tool for facilitating the installation of a bushing assembly within an electrical connector and the subsequent appropriate seating of the electrical connector upon a terminal of an electrical apparatus, preferably from a remote location through the use of an insulated implement, such as a hot-stick.
  • US-A-4,202,591 there is described a high voltage electrical connector of the type employed to connect a high voltage cable to the terminal of an electrical apparatus, such as a transformer, in a power distribution circuit.
  • the electrical connector is provided with a bushing assembly which enables a ground connection to be made so as to ground the terminal without disconnecting the electrical connector.
  • Also disclosed in US-A-4202591 is a tool for grounding the electrical connector and then disconnecting the electrical connector from the terminal.
  • EP-A-0092616 describes an attachment arrangement which facilitates attachment and securing of a bushing assembly to an electrical connector to a terminal of an electrical apparatus, the attachment arrangement including sequentially operated threaded elements and minimum torque responsive devices for assuring that the sequence of operation of the threaded elements will secure the bushing assembly appropriately to the electrical connector and then will secure the electrical connector to the terminal.
  • US-A-2984133 describes a torque limiting tool wherein the shaft of a screw driver is drivably coupled to a handle by means of a torque limiting device. When a predetermined torque is exceeded, the shaft rotates relative to the handle to avoid overtightening.
  • Objects of the present invention are to provide a tool which:-
  • direct coupling means further drivably couple the first and second members to enable the latter relative rotation to take place in one direction, but also to ensure that the first and second members rotate as a unit in the opposite direction when the drive is reversed.
  • a tool constructed in accordance with an embodiment of the invention is shown at 10 and is seen to include an operating member in the form of elongate rod 12 having a wrenching configuration in the form of a hexagonal key 14 at the lowermost end 16 of the rod 12 and wrenching means in the form of a hexagonal drive head 18 adjacent the uppermost end 20 of rod 12.
  • a projection 22 at the uppermost end 20 of rod 12 has a square cross-sectional configuration and is received within a complementary square socket 24 within a cylindrical first body member 26 of tool 10.
  • a pin 28 secures the rod 12 to the first body member 26.
  • Pad eye 30 enables tool 10 to be attached to an insulated implement, such as a hot-stick, in the manner explained fully in US-A-4,202,591, so that tool 10 may be operated by an operator (not shown) from a remote location.
  • a bushing assembly 40 is attached and secured within an electrical connector in the form of a T-shaped receptacle 42, and the receptacle 42 is connected to a terminal 44 (see Figs. 6 and 7) of a high voltage apparatus, such as a transformer (not shown).
  • a high voltage apparatus such as a transformer (not shown).
  • the installation procedure is described in detail in the aforesaid European patent application, serial No. EP-A-0092616 and portions of the procedure are repeated herein to illustrate the use of tool 10 in the procedure.
  • receptacle 42 is affixed to the terminus of a high voltage cable, in the manner illustrated in the aforesaid patent, and an electrical terminal contact 50 having an integral lug 52 is attached to the conductor of the cable. Lug 52 is to be connected to the terminal 44 to complete a distribution circuit.
  • a composite body 54 surrounds the contact 50 and provides an axially extending receptacle recess 56 within which terminal 44 is to be received.
  • a second axially extending recess 58 is to receive interface bushing assembly 40 which is constructed to enable direct connection between the terminal 44 and a commonly available electrical connector, such as an elbow receptacle (not shown).
  • Bushing assembly 40 includes a generally tubular housing 60 having a body member 62 of dielectric material, such as an insulating elastomer, and a central tubular member 64 of conductive material, such as copper or aluminum.
  • the upper end portion 66 of the bushing assembly 40 is essentially the same as that shown in the aforesaid patent.
  • a female contact assembly 68 is located within the tubular member 64 and includes a female contact element 72 which can receive a complementary male contact element (not shown) for completing an electrical circuit to tubular member 64 is provided with an extension in the form of an axially extending tubular extension of a threaded connection 82 at the upper end 84 of tubular extension member 80.
  • the lower end 86 of tubular extension member 80 includes a land 88 for purposes which will be described in greater detail below.
  • a coupling member 90 is received within extension member 80, adjacent lower end 86, and is coupled to extension member 80, adjacent lower end 86, and is coupled to extension member 80 by means of an external thread 92 which extends axially to upper end 94, of coupling member 90 and engages a complementary internal thread 96 in extension member 80.
  • a further external thread 98 extends along the coupling member 90 adjacent the lower end 100 thereof and a collar 102 is located axially between the external threads 92 and 98.
  • coupling member 90 projects beyond the lower end 86 of extension member 80, and the lower end 104 of body member 62 of bushing assembly 40, with collar 102 spaced axially from lower ends 86 and 104, as illustrated in Fig. 3.
  • external thread 98 is spaced far enough downwardly from the tapered portion 106 of the body member 62 of bushing assembly 40 to enable external thread 98 to be engaged with a complementary threaded aperture 108 in lug 52 of contact 50, as seen in Fig. 3, without resistance which might otherwise occur if the tapered portion 106 of the body member 62 were to contact the corresponding tapered portion 110 of recess 58.
  • external thread 98 of coupling member 90 may be threaded into threaded aperture 108 merely by turning bushing assembly 40 manually to advance external thread 98 into threaded aperture 108. Such advancement is continued until a sufficient axial length of thread 98 is engaged within threaded aperture 108 to provide the holding strength necessary to complete the installation of bushing member 40, as described below, and preferably until a stop shoulder 112 on collar 102 is seated against lug 52, as seen in Fig. 4.
  • bushing assembly 40 will advance the coupling member 90 into threaded aperture 108 until stop shoulder 112 is seated properly against lug 52.
  • a locking means is provided between the external thread 92 and the internal thread 96 to lock the coupling member 90 and the tubular extension member 80 against movement relative to one another during threading of the coupling member 90 into the lug 52, at least until the aforesaid sufficient axial length of thread 98 is engaged within threaded aperture 108.
  • the locking means is in the form of a pellet 114 of synthetic resin material, such as nylon, placed within a recess 116 in the wall 118 of coupling member 90 and compressed against internal thread 96 of tubular extension member 80 to establish a prevailing torque which preferably is great enough to preclude the unwanted relative movement.
  • a pellet 114 of synthetic resin material such as nylon
  • the pellet 114 provides a locking means which is responsive to a minimum torque, the minimum torque being of a predetermined value which will assure that the coupling member 90 is sufficiently engaged with lug 52, and preferably engaged up to the position where stop shoulder 112 is seated against the lug 52 before tubular extension member 80 will move relative to coupling member 90.
  • Pellet 114 assures that the minimum torque necessary to engage coupling member 90 properly in lug 52 and preferably to seat coupling member 90 against lug 52 will. be reached before extension member 80 moves relative to coupling member 90.
  • bushing assembly 40 Since the body member 62 of bushing assembly 40 is constructed of elastomeric materials, it becomes impractical to grip the bushing assembly externally to exert the forces necessary to continue turning the bushing assembly as the resistance to turning increases with downward movement. Thus, an internal wrenching means is provided for facilitating the continued rotation of the bushing assembly 40, as follows.
  • coupling member 90 has a control bore 120 passing through the coupling member 90 from end 94 to end 100.
  • a threaded fastener in the form of a bolt 122 extends axially within the bore 120 and has a head 124 and a thread 126.
  • a securing means in the form of a pin 130 extends radially through an aperture 132 in the wall of tubular member 64 and into a corresponding hole 134 in the head 124 of bolt 122, the 130 having a flanged end 136 which serves to locate the pin 130 radially within aperture 132.
  • Tubular extension member 80 overlaps the aperture 132 thereby capturing flanged end 136 of pin 130 within aperture 132.
  • Bolt 122 thus is fixed in the retracted position illustrated in Figs. 4 and 5.
  • a socket 138 in head 124 of bolt 122 provides a hexagonal wrenching configuration located along the central axis A of the bushing assembly 40.
  • Tool 10 having elongate rod 12 with complementary hexagonal key 14, is lowered through the female contact assembly 68 and tubular member 64, along axis A, as seen in Fig. 5, and key 14 is inserted into socket 138.
  • a wrench 150 is engaged with drive head 18 to effect rotation of rod 12 about axis A. Concomitant rotation will be imparted to bushing assembly 40 by virtue of the fact that bolt head 124 is secured to tubular member 64 by pin 130.
  • the bushing assembly 40 It is important that the bushing assembly 40 not be overtightened; that is, the land 88 must not gaul the lug 52 and excessive forces should not be developed along the interface between the complementary tapered portions 106 and 110. At the same time, it is important that at least a minimum torque is applied sufficient to assure proper seating of bushing assembly 40 within receptacle 42. In order to preclude the application of excessive wrenching forces upon the bushing assembly 40, while assuring that the necessary minimum wrenching forces are applied, the shear strength of pin 130 is chosen so that pin 130 will shear in response to the application by tool 10 of a torque in excess of a given value determined by the minimum torque required for the appropriate seating of bushing assembly 40 within receptacle 42 and the maximum torque which can be tolerated.
  • pin 130 serves as a securing means for securing the head 124 of bolt 122 to tubular member 64 for applying wrenching torque, and the securing means releases in response to exceeding a given torque to preclude the application of an excessive torque to the connection between the bushing assembly 40 and the lug 52 while assuring that the necessary minimum torque is applied.
  • bolt 122 is free to move axially downwardly within tubular extension member 80 and coupling member 90, as seen in Fig. 6. It is noted that axially upward movement of bolt 122 is restricted by a lip 156 which projects radially inwardly to preclude movement of bolt 122 upwardly into tubular member 64 beyond lip 156.
  • the bolt 122 Upon freeing of the bolt 122 by shearing of the pin 130, the bolt 122 will drop to the position illustrated in Fig. 6, in preparation for connection of the receptacle 42 to terminal 44.
  • pin 130 has been sheared by the torque applied by wrench 150 directly through drive head 18 to rod 12 and consequently to pin 130 through bolt head 124.
  • bolt 122 is threaded into aperture 158 of terminal 44, as shown in Fig. 7.
  • the head 124 of bolt 122 bears against washers 159 which rest upon the upper end 94 of coupling member 90 such that bolt 122 lamps lug 52 in place upon terminal 44 with an appropriate interference fit established at the interface between the recess 56 of the receptacle 42 and the corresponding outer surface 160 of the terminal 44.
  • Tool 10 is operated to complete the connection between the receptacle 42 and the corresponding outer surface 160 of the terminal 44.
  • Tool 10 is operated to complete the connection between the receptacle 42 and the terminal 44 and to assure the operator that the appropriate interference fit has been established.
  • the operator will remove wrench 150 from drive head 18 and will attach an insulated implement, such as a hot-stick, (not shown) to pad eye 30 so that the tool 10 can be rotated about axis A through manipulation of the insulated implement.
  • Pad eye 30 is affixed to second body member 34 of tool 10 which, in turn, is coupled to first body member 26 so that, ordinarily, rotation of pad eye 30 will result in concomitant rotation of rod 12 and hexagonal key 14 to move receptacle 42 downwardly into engagement with terminal 44.
  • tool 10 provides a torque responsive coupling device between pad eye 30 and rod 12 for indicating to the operator when the predetermined torque has been reached.
  • first body member 26 includes therein a torque limiting mechanism 170 which is coupled to second body member 36 and allows second body member 36 to rotate relative to first body member 26 when the torque applied to pad eye 30 exceeds the aforesaid predetermined torque.
  • the operator knows that he must continue to apply more and more torque to the pad eye 30 as long as both the first and second body members 26 and 36 continue to turn together.
  • the connection is completed, with the appropriate contact made between the receptacle 42 and the terminal 44, and rotation can be discontinued.
  • the same torque limiting mechanism 170 also serves to preclude overtightening of the connection.
  • Torque limiting mechanism 170 is best illustrated in Fig. 1.
  • First body member 26 includes a cylindrical bore 172 having a bottom 174.
  • a plurality of load bearing elements, shown in the form of balls 176 are located in a ring around the bottom 174, each ball ordinarily being seated within a complementary recess 178 in the bottom 174 of bore 172.
  • a drive disk 180 rests upon balls 176 and includes a plurality of recesses 182 corresponding to the number of balls 176 and being complementary thereto so that each ball 176 ordinarily is seated within a recess 182, as well as within a recess 178.
  • Resilient biasing means in the form of a spring washer 184 is urged against the drive disk 180 by a retainer 186 which is threaded axially into bore 172 and against the spring washer 184 to bias the drive disk 180 against the balls 176.
  • a drive shaft 190 is integral with drive disk 180 at lower end 192 of the drive shaft 190 and extends upwardly to an upper end 194 where the drive shaft 190 is received within a complementary socket 196 in second body member 36 and is affixed to the second body member 36, as by a spring pin 198.
  • drive shaft 190 Upon rotation of pad eye 30 and second body member 36, drive shaft 190 will be rotated and will cause drive disk 180 to rotate. As long as the torque necessary to rotate rod 12 remains below the predetermined torque, drive disk 180 will be coupled to first body member 26 by virtue of balls 176 in recesses 178 and 182. However, when the torque necessary to rotate rod 12 exceeds the predetermined torque, further rotation of drive disk 180 will be resisted by balls 176 and drive disk 180 will be urged axially upwardly against the bias of spring washer 184 to enable drive disk 180 to ride over the balls 176 to continue to be rotated in response to rotation of second body member 36 and drive shaft 190, while the first body member 26, and rod 12, remain stationary.
  • the value of the torque at which relative rotation is permitted between the first and second body members 26 and 36 is determined by the axial biasing force of spring washer 184 and may be set by appropriate adjustment of the axial position of retainer 186. Once the axial position is determined, retainer 186 is locked into place by a threaded locking member 188 which is threaded into bore 172 and abutted with retainer 186 to lock retainer 186 in place. A set screw 199 assures that locking member 188 is fixed in place relative to first body member 26.
  • tool 10 When it is desired to employ tool 10 to remove bolt 122 from threaded aperture 158 of terminal 44, it may become necessary to exert a torque upon bolt 122 greater than the predetermined torque with which the bolt 122 was tightened. Since such removal also should be accomplished from a remote location through the manipulation of tool 10 with an insulated implement, such as a hot-stick, tool 10 is provided with means for directly coupling the first body member 26 with the second body member 36 when the pad eye 30 is rotated in a direction opposite to the direction of rotation employed during the above-described installation procedure.
  • the direct coupling means includes a drive tooth 200 located within a hole 202 in second body member 36 and resiliently biased by a helical spring 204 downwardly into a groove 206 located in a plate 208 placed between the first and second body members 26 and 36.
  • Plate 208 is secured for rotation with first body member 26 by virtue of a post 210 projecting upwardly from locking member 188 and engaging a complementary drive aperture 212 in plate 208.
  • Post 210 is integral with locking member 188 and has a square cross-sectional configuration which engages a complementary square plan configuration of drive aperture 212 so that plate 208 and first body member 26 will rotate as a unit.
  • groove 206 has a ramp 214 at one circumferential boundary and an axial shoulder 216 at the opposed circumferential boundary.
  • tool 10 provides a relatively simple, yet rugged device for use in the field by a workman for attaching and securing a bushing assembly 40 to a receptacle 42, for connecting the receptacle with a terminal 44 with the desired interference fit, from a remote location utilizing an insulated implement, such as a hot-stick, and for disconnecting the receptacle from the terminal from a remote location.
