  • an enlarged view of a partition plate 7 is shown in part A
  • an enlarged view of a shutter cover 8 is shown in part B.
  • the horizontal direction of the board of the control center 100 is designated as the X direction, the depth direction as the Y direction, and the vertical direction as the Z direction.
  • the partition plate 7 serves to separate the busbar room 5 in which the busbars 6 of the control center 100 are arranged from the functional unit room 4 in which the functional units 1 are inserted.
  • the shutter cover 8 is attached to this partition plate 7. Since the shutter cover 8 needs to move laterally when the functional unit 1 is inserted, it is not fixed to the partition plate 7 with screws or the like, but is attached by clamping the upper and lower parts of the partition plate 7 with stoppers 15 provided on the top and bottom of the shutter cover 8. Furthermore, a spring 12 is attached between the partition plate 7 and the shutter cover 8 so that the shutter cover 8 returns to its original position (the position hiding the bus bar 6) by elastic force when the functional unit 1 is pulled out of the functional unit chamber 4.
  • the shutter cover 8 has a front protrusion 9 at one end, either left or right (X direction).
  • X direction a case will be described in which the front protrusion 9 is provided at the left end of the shutter cover 8 when the functional unit 1 is viewed from the front panel.
  • This front protrusion 9 is structured to protrude in the front direction (i.e., in the Y direction toward the front panel of the functional unit 1) from the bottom side of the shutter cover 8, and is positioned so that it can be slipped under the bottom plate 13 of the functional unit 1 when it is inserted into the functional unit chamber 4.
  • the front protrusion 9 is provided with a test position protrusion 10 so that the functional unit 1 feels a catch when it is inserted or pulled out to the test position.

  • FIGS. Fig. 2 is a front view of the state in which the shutter cover 8 is attached to the partition plate 7 and before the functional unit 1 is inserted
  • Fig. 4 is a top view of this state.
  • the shutter cover 8 Before the functional unit 1 is inserted into the functional unit chamber 4, the shutter cover 8 has not yet moved sideways, so the busbar 6 in the busbar chamber 5 is not exposed as shown in Fig. 2.
  • Fig. 3 shows the state after the functional unit 1 has been fully inserted and the shutter cover 8 has moved sideways. In this state, the positions of the busbar openings 14 provided on the shutter cover 8 and the partition plate 7 are aligned, so the busbar 6 in the busbar chamber 5 is exposed and the junction 2 attached to the functional unit 1 can be connected to the busbar 6.

  • Part A in Fig. 5 is an enlarged view of the spacer 11. 5
  • a spacer 11 is provided on the underside of the bottom plate 13 of the functional unit 1.
  • the spacer 11 in order to avoid the risk of the spacer 11 becoming stuck due to friction when it comes into contact with the front protrusion 9, it is preferable that the spacer 11 be flat and circular in shape and parallel to the front protrusion 9. It is also preferable that the spacer 11 be made of metal rather than resin so that it is not damaged when it comes into contact with the front protrusion 9.
  • the spacer 11 rotatable about its circular central axis, no friction occurs between the spacer 11 and the front protruding portion 9, so that the functional unit 1 can be inserted and pulled out more smoothly.

At the same time that the functional unit 1 is inserted into the functional unit chamber 4, the spacer 11 presses against the front protrusion 9 of the shutter cover 8, and in conjunction with this, the shutter cover 8 moves sideways.
  • Figures 6 to 8 each show a cross-sectional view of the functional unit 1 as seen from above.
  • Figure 6 shows the functional unit 1 in a position where the spacer 11 comes into contact with the front protrusion 9 of the shutter cover 8 when it is inserted into the functional unit chamber 4.
  • Figure 7 shows the functional unit 1 inserted up to the test position.
  • Figure 8 shows the functional unit 1 inserted further, with the junction 2 of the functional unit 1 connected to the busbar 6.
  • the elastic force of the spring 12 attached to one end of the shutter cover 8 causes the shutter cover 8 to move laterally as the functional unit 1 is pulled out from the functional unit chamber 4, thereby preventing the busbar 6 from being exposed.
  • a shutter mechanism of a control center of a comparative example will be described with reference to Figures 9 to 11.
