Definitions

  • the present invention relates to an operating mechanism for a switch, and more particularly to an operating mechanism for a switch designed to have both functions of a disconnecting switch and an earthing switch and to be switched between three positions "CLOSED", "OPEN” and "EARTHED” by a single operating unit.
  • FR-A-1206991 relates to a multipolar electric switch for high tension currents. It discloses a mechanism in which a switch can be put instantaneously in a circuit, or out of the circuit by releasing a pawl. The mechanism comprises an axis, a lever ensuring the movement upwards and downwards and transforming the rotational movement and a roller attached to the lever. Furthermore, Japanese Patent Laid-Open Publication No. 2003-22735 (Patent Publication 1) discloses an operating mechanism for such a three-position switch.
  • the operating mechanism disclosed in the Patent Publication 1 is designed to rotate an output shaft using either a motor or a manual handle so as to operate the three-position switch between "CLOSED", “OPEN and “EARTHED”. More specifically, the operating mechanism comprises: a cam plate fixed to the output shaft and formed with three depressions at positions corresponding to the switch positions "CLOSED”, “ OPEN “and” EARTHED "; pins formed on a surface of the cam plate and adapted to be brought into contact with four limit switches for stopping the motor; a cam-follower lever which is provided with a locking roller and a on-cam rolling roller biasedly pressed onto and rolled along a circumferential edge of the cam plate, and adapted to be vertically moved according to a rotation of the cam plate; a retaining latch formed with a concave portion and adapted to allow the locking roller to be engaged with the concave portion when the on-cam rolling roller is located at each of the depressions of the cam plate corresponding to the switch positions "CLOSED", “OPEN” and "
  • the present invention is directed to provide a switch operating mechanism capable of achieving enhanced accuracy in a stop position of a switch during an electric motor-based operation and in a stop position of the switch (in detachable position of a manual handle) during a manual handle-based operation, while reducing the number of auxiliary relays to simplify a control system.
  • FIG 1 is a perspective view showing an operating mechanism according to one embodiment of the present invention.
  • the operating mechanism is designed to transmit a torque of a motor 1 to a grooved cam shaft 5 through a spur gear 3 of a motor shaft 2 and a spur gear 4 engaged with the spur gear 3.
  • a manual handle 6 may be connected to the motor shaft 2 to rotate the spur gear 4 so as to rotate the grooved cam shaft 5.
  • the manual handle 6 is formed with a groove 7, and an inhibition plate 8 for inhibiting the manual handle 6 from being inserted and pulled out from the motor shaft 2 is disposed adjacent to the groove 7 in an engageable manner relative to the groove 7.
  • the inhibition plate 8 is biased in a direction away from the groove 7 by a spring 9.
  • the grooved cam shaft 5 has an outer peripheral surface formed with a groove 10 axially extending continuously like a spiral.
  • the groove 10 receives therein a roller 13 which is attached to one end of a lever 12 having the other end fixed to an output shaft 11 associated with a switch.
  • the roller 13 is swung rightward or leftward (in FIG 1 ) about the lever 12 while being guided along the groove 10.
  • a cam plate 14 is fixed to one end of the grooved cam shaft 5.
  • the cam plate 14 is formed with a concave portion 15 adapted to be engageable with a bump roller 17 attached to a first end of a T-shaped cam-follower lever 16.
  • the cam-follower lever 16 is biased by a reset spring 18 attached to a second end thereof in such a manner as to allow the bump roller 17 to be engaged with the concave portion 15.
  • a limit switch 20 is activated by the pushed cam-follower lever 16 to detect this state and turn on a drive circuit of the motor 1.
  • the operating mechanism is in an intermediate position ("OPEN” position in the case of the switch has three positions “CLOSED”, “OPEN” and “EARTHED”). In this position, the bump roller 17 falls in the concave portion 15 of the cam plate to lock the rotation of the grooved cam shaft 5.
  • the release coil 19 is energized according to the control unit to push the cam-follower roller 16.
  • the cam-follower roller 16 is swung clockwise against the reset spring 18, and the bump roller 17 is moved to disengage from the concave portion 15 of the cam plate 14 so as to allow the grooved cam plate 5 to be rotated.
  • the limit switch 20 detects this state and turns on the drive circuit of the motor 1.
  • the motor 1 is rotated, and a torque of the motor 1 is transmitted to the grooved cam shaft 5 through the spur gears 3, 4 to rotate the grooved cam shaft 5 counterclockwise.
  • the roller 13 engaged with the groove 10 of the grooved cam shaft 5 is driven or swung leftward (in FIG 1 ), and the output shaft 11 is rotated through the lever 12 in a counterclockwise direction (direction to the "CLOSED" position).
  • the bump roller 17 is placed and rolled on a circular circumferential surface of the cam plate 14 to maintain the rotatable state of the grooved cam shaft 5.
  • the limit switch 20 detects this state to de-energize the release coil 19.
  • the limit switch 20 detects this state to turn off the drive circuit of the motor 1. While the motor 1 inertially rotates for a while, it will be completely stopped when the bump roller 17 bumps against a wall surface of the concave portion 15 of the cam plate.
  • FIG 2 shows one example of the configuration of the groove 10 of the grooved cam shaft 5
  • FIG 3 is a graph showing the groove configuration.
  • FIG. 4 is a graph showing a torque conversion rate in the groove configuration.
  • the groove 10 is configured to have no axial displacement around each of three positions corresponding to the three stop positions of the switch. Thus, even if the bump roller 17 is stopped at any position within the concave portion 15 of the cam plate 14, a stop position of the output shaft 11 is not varied.
  • an axial displacement rate relative to an angle of the groove 10 is arranged to become smaller on the side of the "CLOSED” and “EARTHED” positions and become larger on the side of the "OPEN” position.
  • a torque conversion rate output shaft torque/motor shaft torque
  • the bump roller 17 falls in the concave portion 15 of the cam plate 14 to lock the rotation of the grooved cam shaft 5, and the inhibition plate 8 is returned to its initial position to allow the manual handle 6 to be inserted and pulled out from the motor shaft 2.
  • the grooved cam shaft 5 When the manual handle 6 is rotated clockwise, the grooved cam shaft 5 is rotated counterclockwise. Thus, the roller 13 engaged with the groove 10 of the grooved cam shaft 5 is driven or swung leftward (in FIG 1 ), and the output shaft 11 is rotated through the lever 12 in a counterclockwise direction (direction to the "CLOSED" position).
  • the bump roller 17 In the state after the grooved cam shaft 5 is rotated at some degrees, the bump roller 17 is placed and rolled on the circular circumferential surface of the cam plate 14 to maintain the rotatable state of the grooved cam shaft 5.
  • the limit switch 20 detects this state to de-energize the release coil 19.
  • the inhibition plate 8 is engaged with the groove 7 of the manual handle 6 to inhibit the manual handle 6 from being pulled out of the motor shaft 2.
  • the bump roller 17 falls in the concave portion 15 of the cam plate 14, and the cam-follower lever 16 is swung counterclockwise.
  • the bump roller 17 bumps against the wall surface of the concave portion 15 of the cam plate 14 to completely stop the grooved cam shaft 5.
  • the inhibition plate 8 is returned to the initial position by the spring 9 to allow the manual handle 6 to be inserted and pulled out from the motor shaft 2.
  • the switch operating mechanism according to the above embodiment has the following effects.
