Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perforated handle provided on a rear plate of a switchboard. 2. Description of the Related Art FIG. 2 shows the structure of a switchboard. The inside of the casing 1 is partitioned by a partition wall 2, 3, 4, 5 into a power bus room 6, a load bus room 7, and circuit breaker rooms 8.9. 10a is a main bus, 10 is a power bus, 11a and 11b are load buses,
12 and 13 are circuit breakers, and 14 is a cable. Current transformers (CT) 15a, 15b are provided on the load buses 11a, 11b, respectively. [0003] A rear plate 16 is detachably provided on the rear surface of such a switchboard. The rear plate 16 is attached such that the upper part is hooked on the housing 1 and hung. In addition, a perforated handle (not shown) is configured to configure a handle for lifting the back plate 16. The perforated handle is such that the back plate 16 is lifted by inserting a hand through the hole, and a cushioning material for protecting the hand is attached around the hole. [0004] However, since air enters and exits through the hole of the perforated handle, a large amount of external dust enters the housing after a long period of time and accumulates. I do. In some cases, it may adhere to conductors and cables and cause a fire. [0005] Therefore, an object of the present invention is to provide a switchboard which solves such a problem. According to a first aspect of the present invention for achieving the above object, an opening is provided in a housing, and the opening is closed with a closing plate. In a switchboard provided with a perforated handle, an elastic member for closing the hole is attached to the inside of the perforated handle, and a slit is formed on the elastic member to allow a finger to pass therethrough. It is characterized. Normally, the hole of the perforated handle is closed by the elastic member, so that dust is prevented from entering the inside of the housing. On the other hand, when removing the closing plate, the hand can be penetrated through the elastic member by putting a hand through the slit, and the closing plate can be lifted with a large force. Hereinafter, embodiments of a switchboard according to the present invention will be described. (A) Embodiment FIG. 1 shows an embodiment. FIG. 1A is a view of the back plate (blocking plate) 16 as viewed from the back of the switchboard. A handle guard 19 serving as a cushioning material is adhered around the hole 18a constituting the perforated handle 18, and when the back plate 16 is lifted by putting a hand in the hole 18a, the weight of the back plate 16 depends on the weight. The hand is not scratched. Inside the back plate 16, a rectangular sponge (expandable member) 20 having a size sufficiently larger than the hole 18a is attached so as to close the hole 18a. A slit 21 that penetrates the sponge 20 at a position where it is divided into two
Is formed. In such a switchboard, the hole 18a is normally closed by the sponge 20, and external dust does not enter the switchboard. When the back plate 16 is to be removed or mounted in reverse, a hand is inserted into the hole 18a and the slit 21 is removed.
Is passed through the sponge 20 and the rear plate 16 is lifted. The elastic member is not limited to a sponge, but may be a rubber sheet or various sheet members made of an elastic material. As can be seen from the above description, claim 1
According to the switchboard according to the above, on the inside of the perforated handle, an elastic member that closes the hole is attached, and the elastic member is formed with a slit for allowing the passage of a finger. The hole is closed by the presence of the hole, and when removing the closing plate, the hand can be penetrated from the slit to a position penetrating the elastic member, so that a large force can be exerted when lifting the closing plate.
