BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment Corresponding to Claim 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a schematic configuration of a first embodiment of the present invention, which has the following configuration. FIG.
As in the conventional example shown in FIG. 1, a switch gear 1 having a power supply terminal (not shown) at a predetermined position on the back side, and a main circuit terminal which can be inserted into and removed from the switch gear 1 and which can be connected to and separated from the power supply terminal ( A storage device 5 having 14) of FIGS.
A guide rail 3 installed on the floor of the switch gear 1 for defining the moving direction of the storage device 5 and having lock pin insertion grooves 4 at positions corresponding to the connection position and disconnection position of the storage device 5; An interlock pin 6 that is vertically movably supported by the device 5 and falls when the storage device 5 is located at the connection position and the disconnection position and fits into the lock pin insertion groove 4 to prevent the storage device 5 from moving. I have. The configuration so far is the same as the conventional one, and a new interlock pin 6 is provided.
When the storage device 5 is at the connection position or the disconnection position, it is stored inside the storage device 5 and when the storage device 5 is at a position other than the connection position or the disconnection position.
Is provided with an indicator comprising a plate 9 protruding to the outside and a nameplate 10 attached to the plate 9.

FIG. 2 is a detailed view of the interlock pin 6 and the display.
It may be either (a) or FIG. 2 (b). FIG.
(A) is a plate in which a plate 9 is welded to a metal T-shaped round bar 7 and a name plate 10 is attached to the plate 9. FIG. 2B shows a case where the plate 9 is welded to the plate 8 and the name plate 10 is attached to the plate 9.

3 and 4 are side views of the storage device 5. FIG.
As shown in FIG. 3, in the normal state (interlock pin 6
Is not in the lock pin insertion groove 4 of the guide rail 3), the name plate 10 of the plate 9 is
Projecting outside. From this state, it can be seen that the storage device 5 is at a position other than the connection position and the disconnection position.

However, as shown in FIG. 4, the interlock pin 6 enters the lock pin insertion groove 4 of the guide rail 3, and when the interlock pin 6 operates, the nameplate 10 attached to the plate 9 becomes invisible. Thereby, the operation state of the interlock pin 6 can be easily determined and confirmed.

(Embodiment Corresponding to Claim 2) Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a perspective view showing a schematic configuration of the second embodiment, and FIG. 6 is a perspective view showing a detailed view of an interlock pin and a display.

The second embodiment differs from the first embodiment in the configuration of the storage device 5, the interlock pin 6, and the display. That is, a display window 11 for displaying the state of the interlock pin is provided on the front panel of the storage device 5. The plate 9 and the nameplate 10 constituting the display are mounted on the center of the interlock pin 6 as shown in FIG.

The interlock pin 6 is made of either a round bar 7 made of metal as shown in FIG. 6A or a plate 8 as shown in FIG. The name plate 10 is attached to the plate 9 by welding. In this case, the nameplate 10 is almost the same size as the display window 11, and when the interlock pin 6 is completely dropped into the lock pin insertion groove 4 or in a normal state, The nameplate 10 attached to the interlock pin 6 can be seen from the display window 11. Thereby, the state of the interlock pin 6 can be easily confirmed.

(Embodiment Corresponding to Claim 3) A third embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a perspective view showing a schematic configuration of the third embodiment of the present invention. The difference from the first embodiment is the configuration of the storage device 5, the interlock pin 6, and the display.

A display window 11 is provided at the center of the front panel of the storage device 5. Also, an interlock pin 6,
The plate 9 and the nameplate 10 constituting the display are shown in FIGS.
Is supported by the rotating device 12 configured as described above.

The rotating device 12 welds the plate 9 to a metal L-shaped round bar 7 as shown in FIG. 8A or an L-shaped plate 8 as shown in FIG. A name plate 10 is attached to the plate 9, and a support bar 13 is fixed to the bent portion of the round bar 7 or the plate 8 by welding. This rotating device 1
2 is fixed by welding the support rod 13 to the back side of the front panel of the storage device 5 and has its own weight that is not influenced by vibration when the storage device is moved.

The center of gravity is one side of the round bar 7 or the plate 8 a
Side, and always tilts to the side a with the support rod 13 as an axis. When the interlock pin 6 is lowered, it rotates in the direction B, and the nameplate 10 is attached to the display window 11 provided in the storage device 5.
Is displayed. The nameplate 10 is horizontal in this state.

When the interlock pin 6 returns to the normal state, the interlock pin 6 is supported by the interlock pin 6 and attempts to rotate in the direction C. Therefore, the nameplate 10 is hidden by the front panel of the storage device 5 and is not displayed. . Thereby, the state of the interlock pin 6 can be easily confirmed.
