FIG. 6 shows the detailed connection structure of the slide lever of the operating device, from (a) the normal cut position to (d) the slide lever pulled-out position.

  In FIG. 1A, a lock plate 21 is disposed on the front surface of the operating device, and the handle insertion port 22 is closed. The lock plate 21 is fixed with a padlock 23. Inside the front cover, a micro switch 27 is arranged on the top for the purpose of detecting motion. A slide lever 30 is arranged in a direction perpendicular to the operation shaft 29, and a stopper 24 for fixing the slide lever 30 at an end portion and a stopper base 25 for preventing the slide lever 30 from being pulled out are arranged. Yes. Further, on the horizontal plane of the stopper 24, a stopper fixing bolt 27 for fixing the stopper 24 and an indicator pin 26 for knowing the position of the stopper are arranged.

  As shown in FIG. 1B, when the slide lever 30 is pulled out, a guide plate 31 for fixing the slide lever 30 is also arranged. A handle guide 32 is disposed in a hole in which the end portion of the slide lever 30 is processed, and is fixed by a stopper bolt 28 and a plunger 29 via the slide lever 30 from the outside.

  FIG. 2A shows the state before and after the steering operation, and the state is off. The operation procedure will be described. First, the padlock 23 is removed and the lock plate 21 is opened. The stopper fixing bolt 27 is loosened, and the operation handle 35 of (b) is inserted into the handle insertion port 22 as far as possible, and is rotated about 90 ° in the clockwise direction. Due to the rotation, the stopper 24 is disengaged from the stopper base 25, the fixation of the slide lever 30 is released, and the drawer 24 can be pulled out.

  FIG. 6A shows a detailed structure of the slide lever portion in the normal cut position. The relay boss 40 connected to the operation shaft 29 of the operation device is disposed on the left side with respect to the slide lever 30 and is engaged with the fixing groove 38. A relay shaft 42 arranged with the slide lever 30 on the opposite side of the relay boss 40 is also engaged with the fixed groove 38. The operation shaft 29 is connected to the connecting lever 43 via the relay boss 40, the slide lever 30, the bearing 41, and the relay shaft 42.

  FIG. 2B shows a state where the operation handle 35 is inserted into a groove formed in the slide lever 30. At the time of insertion, the pin 36 at the tip of the operation handle 35 engages with a notched portion (escape groove 37) of the handle guide 32 so that the slide lever 30 can be pulled out.

  FIG. 6B shows a detailed structure of the slide lever portion at the normal position. 6A, when the operation shaft 29 is rotated, the relay boss 40, the slide lever 30, the relay shaft 42, and the connecting lever 43 are integrally rotated. In the groove arranged on the left side with respect to the slide lever 30, the operation shaft 29 side becomes the fixed groove 38 together with the relay shaft 42 side. Thereby, when the operating device itself operates, the connected load also operates.

  FIG. 3A shows a state where the slide lever 30 is pulled out. In FIG. 3B, the handle guide 32 is restricted to rotate about 45 ° by the stopper bolt 33, and a plunger 34 is provided for positioning the handle guide 32. For this reason, even if the stopper fixing bolt 27 in FIG. 3A is forgotten to be tightened, the stopper 24 is prevented from moving to prevent malfunction.

  FIG. 6C shows the cut position when the slide lever is pulled out. The relay boss 40 connected to the operation shaft 29 is disposed on the right side with respect to the slide lever 30, and the engagement between the operation shaft 29 and the slide lever 30 is released by the action of the escape groove 37. Of the grooves arranged on the opposite side of the relay boss 40 via the slide lever 30, the operation shaft 29 side is the escape groove 37 and the relay shaft 42 side is the fixed groove 38.

  Here, the relationship between the operation handle 35 and the handle guide 32 will be described with the slide lever 30 pulled out. With the operation handle 35 rotated by about 90 ° in the clockwise direction, the slide lever 30 is pulled out and placed in front of the notch portion of the guide plate 31. In this state, the handle insertion port 22 and the pin 36 at the distal end of the operation handle 35 interfere with each other so that the operation handle 35 is not pulled out.

  FIG. 4A shows a state where the slide lever 30 is fixed after the slide lever 30 is pulled out. This time, the operation handle 35 is rotated counterclockwise by about 90 °, and the stopper 24 is engaged with the guide plate 31 to fix the slide lever 30. By rotating the stopper 24, it is possible to output a signal to the outside by operating the micro switch 28.

  FIG. 4B shows the relationship between the operation handle 35 and the handle guide 32 when the stopper 24 is fixed after the slide lever 30 is pulled out. The position of the pin 36 at the distal end of the handle insertion opening 22 and the operation handle 35 is matched, and the operation handle 35 can be pulled out.

  FIG. 6D shows the entry position when the slide lever is pulled out. 6C, when the operation shaft 29 rotates, it rotates to the relay boss 40, but the relay shaft 42 and the connecting lever 43 ahead do not rotate. Thereby, even if the operating device itself rotates, the connected load does not operate.

  FIG. 5A shows the state of operation completion. The stopper fixing bolt 27 is tightened to fix the stopper 24 to the slide lever 30. Return the lock plate 21 to its original position and lock it with a padlock 23. The lock plate 21 prevents the operation by closing the handle insertion opening 22, and prevents the indicator pin 26 from rotating erroneously. In addition, the indicator pin 26 protrudes to the front, thereby enabling display during operation.

  FIG. 5B shows the relationship between the operation handle 35 and the handle guide 32 after the operation is completed. The normal state can be restored by performing the reverse operation of the above contents.

  As described above, in this embodiment, the slide lever 30 is provided in the operation shaft portion inside the operation device, and the operation shaft 29 and the slide lever 30 are normally engaged with the fixing groove 38 formed in the slide lever 30. The structure moves at the same time. By moving the slide lever 30 to the left side, when the operation shaft 29 is disposed in the escape groove 37 formed in the slide lever 30, the engagement between both is disengaged, and the operation shaft 29 and the slide lever 30 are separated from each other. The operating device can operate even when the shaft 29 is fixed.

  According to this, the disconnector and grounding switch mechanism are fixed without disconnecting the connection mechanism of the disconnector and grounding switch, the controller side is free, and the test for each line is easy even when the bus is charging. The test work efficiency and safety can be improved.
