In other words, IP65 grade means dust-proof performance with little ingress of solids including dust (standard of IP dust-proof grade 6) and waterproof performance against low-pressure water flowing between the door and the enclosure (standard of IP waterproof grade 5) refers to the case of providing

The present invention is technically characterized in that when the door is closed in the switchboard, the sealing member is compressed between the protruding piece and the inner circumferential surface of the door to seal the inside of the switchboard, thereby providing IP65 dustproof and waterproof performance.

2 is a schematic illustration of a switchboard having an IP65 waterproof and dustproof rating according to the present invention, and the present invention includes a protruding piece 100 and a sealing member 200 .

The protruding piece 100 is vertically protruded forward from the inner edge of the rim 12 surrounding the opening 11 in the front of the housing.

The protruding piece 100 preferably has a predetermined length so that the sealing member can be smoothly compressed by supporting the sealing member to be described later when the door 20 is closed. It is preferable to have a predetermined thickness so that it does not occur.

The sealing member 200 is fixed along the inner circumferential surface of the door 20 in a form facing the end of the protruding piece 100, and is compressed between the protruding piece and the door when the door is closed. Seal the inside.

In the present invention made as described above, when the sealing member 200 is fixed to the inner circumferential surface of the door 20 and the door is closed, the entire end surface of the protruding piece 100 is in close contact with the sealing member 200 inside the enclosure 100 . can be effectively sealed, and through this, it is possible to prevent moisture or dust from entering from the four corners of the door 20 .

Next, FIG. 3 is a schematic illustration showing a protruding piece according to a preferred embodiment of the present invention. In the present invention, the protruding piece includes a vertical piece and an inclined piece.

The vertical piece 110 is formed to protrude vertically from the inner edge of the rim.

The vertical piece 110 is preferably formed to have an appropriate length so as to be spaced apart from the inner circumferential surface of the door by a predetermined distance.

The vertical piece 110 preferably has a predetermined thickness to prevent bending deformation or short circuit due to external force applied when the sealing member is compressed by the inner circumferential surface of the door when the door is closed.

The inclined piece 120 is inclined at a predetermined angle along an outer diagonal direction from an end of the vertical piece.

Preferably, the inclined piece 120 may be inclined at an angle of 120 to 150° with respect to the vertical piece.

In addition, the inclined piece 120 is made of a material having excellent strength and elasticity, and provides a buffering effect against external force acting while being in close contact with the sealing member when the door is closed, and supports the sealing member to provide a cushioning effect for the door. By allowing the sealing member to be compressed by the external force acting from the door, the airtightness of the door is more reliably maintained.

Next, in the present invention, the sealing member 200 may be a semi-circular packing.

When the packing 200 is pressed by the inner circumferential surface of the door, it is compressed while being finely crushed along the inclined surface of the inclined piece, thereby providing the effect of improving the sealing efficiency of the inside of the housing.

In addition, the packing 200 is made in the form of a semi-circular filled inside to absorb the impact when in contact with the sealing member, thereby minimizing the impact transmitted to the inclined and vertical pieces, there is a remarkable effect that can secure the durability of the protruding piece.

5 is an exemplary view showing a conventional general switchboard.

5, in the conventional switchboard, an opening 2 is formed in the center of the front panel 1a of the housing 1, and the entire edge of the opening 2 is bent at right angles to protrude the protruding piece 11 and the protrusion. A protrusion 10 including a protruding end 12 is formed by bending the end of the piece outward so as to be parallel to the front panel 1a.

In such a conventional switchboard, one side of the housing (1) and one side of the door (3) are connected and mounted with a hinge device (4) by fitting and fixing the sealing packing (6) to the protruding end (12), and the hinge device (4) ), the door 3 opens and closes the opening 2 of the housing 1, and when the door is closed, the sealing packing is compressed by the door to seal the inside.

However, in the switchboard, as the sealing packing 6 is mounted on the protrusion 10 constituting the edge of the opening 2, the sealing packing 6 provided in the lower part of the opening 2 is peeled off or damaged by the occupants. There was a problem that occurred frequently.

In addition, since the part in close contact with the door is made of a hollow structure with an empty interior, the impact applied from the door is transmitted to the protruding end 12 when the door is closed, so that the protruding end 12 and the protruding piece 11 are durable. This was bound to continue to decline.

In contrast, in the present invention, the packing 200 is fixed to the inner circumferential surface of the door, so that the contact area with the inclined piece is remarkably widened, thereby maximizing the sealing function, as well as minimizing separation or damage caused by repeated opening and closing of the door.

In addition, as the packing 200 is fixed to the inner circumferential surface of the door, it is possible to prevent the case of applying pressure to the packing when performing maintenance, repair, etc. through the opening in the open state of the door, thereby preventing damage to the packing Through this, it is possible to maintain the sealing function continuously and stably by prolonging the life of the packing.

Furthermore, by using the packing 200 in the form of a filling inside as a sealing member, the effect of extending the life of the entire enclosure can be expected by ensuring the durability of the protruding piece by making a buffer action against the impact applied when the door is closed.

The present invention as described above can satisfy the IP65 rating by effectively sealing the inside of the housing while the sealing member is compressed between the protruding piece and the door.

Meanwhile, although not shown in the drawings, it goes without saying that the protruding piece and the sealing member according to the present invention can be applied to a switchboard in which a plurality of doors are mounted in the housing.
