Description

Terminal box cover with bending prevention structure {A TERMINAL BOX COVER HAVING WARPAGE PREVENTION STRUCTURE}

The present invention relates to a terminal box cover mounted on a case embedded in the wall of the building.

In general, many terminal boxes are buried inside walls when all buildings are constructed. In particular, in apartments, terminal boxes are installed every second and sixth generation.

The terminal box consists of a box-shaped case and a cover of which one side is open. The case of the terminal box is embedded in the wall, the cover is installed on the front of the case in order to beautifully protect the appearance or the terminal block (not shown) installed inside the case.

With the recent launch of large terminal boxes, the following problems arise in product quality.

In general, the terminal box cover and case are made of plastic injection molding. The case is a part that is embedded in the wall surface, and even if a small deformation (bending phenomenon) occurs due to shrinkage, it is not a big problem, but the cover exposed to the outside is very sensitive to the small deformation. In the case of a product having a width of 300 mm or more in general, a warpage phenomenon occurs in the cover.

In more detail, a phenomenon in which the center portion of the door 14 of the terminal box cover 10 is lifted (bending) occurs, so that the center portion of the door 14 protrudes from the frame 12 as shown in FIG. 5. .

As such, since the door 14 is not closed smoothly to the frame 12 of the cover 10, there is a disadvantage that the quality of the product is greatly reduced, and the appearance is not beautiful.

The present invention is to solve such a problem, an object of the present invention is to provide a new type of terminal box cover to prevent the door is closed to be closed to the frame.

According to a feature of the present invention for achieving the above object, the terminal box cover has a door formed with at least one protrusion formed on the edge, and a frame formed with a fitting groove to be coupled to the protrusion at a position corresponding to the protrusion of the door. .

In a preferred embodiment of the present invention, the protrusion may be formed in a hook shape.

In a preferred embodiment of the present invention, the frame has a through hole consisting of an arc-shaped long hole having a concentric circle with respect to the center of the frame.

For example, embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited by the embodiments described below. This embodiment is provided to more completely describe the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings and the like are exaggerated to emphasize a clearer description.

Hereinafter, an embodiment of the present invention will be described in more detail with reference to FIGS. 1 to 4. In the drawings, the same reference numerals are given to components that perform the same function.

1 is a perspective view showing a terminal box cover according to an embodiment of the present invention. 2 is a front view of a terminal box cover according to a preferred embodiment of the present invention. 3 is a cross-sectional view taken along the line A-A shown in FIG. 4 is a view showing another modified example of the projection.

1 to 3, the terminal box cover 120 of the present invention includes a rectangular frame 122 and a door 128 hinged to the frame 122.

Through-holes 126 are formed in the flange 124 of the frame 122 to correspond to the screw holes of the terminal box case. These through holes 126 are made of an arcuate long hole. The frame 122 is fixed to the case by screws that are fastened to the screw holes through the through holes 126.

On the other hand, the door 128 is hinged to the frame 122 of the cover 120. A plurality of grid-shaped ribs 129 are formed on the rear surface of the door 128 to prevent deformation and reinforce strength due to shrinkage. Two protrusions 130 are formed at upper and lower edges 128a and 128b of the door 128 of the door 128, respectively. For example, the protrusion 130 is preferably located close to the center portion of the door. In addition, the flange 124 of the frame 122 corresponding to the protrusion 130 is provided with a fitting groove 132 into which the protrusion 130 is fitted.

When the door 128 is closed to the frame 122, the protrusion 130 is fitted into the fitting groove 132 formed in the flange 124 of the frame 122, the center portion of the door 128 is lifted Will be prevented.

Here, the structural feature of the present invention is to have a lifting prevention structure of the door consisting of a projection and a fitting groove in the door and the frame, respectively. The terminal box cover of the present invention is very usefully applicable to a large size cover having a length of 300 mm or more because the door is closed to the frame and the protrusion of the door is blocked while the protrusion is inserted into the fitting groove.

The cover 120 according to a preferred embodiment of the present invention can be modified in the size or shape of the terminal box within the technical scope of the present invention.

The present invention is not limited only to the structure of the illustrated embodiment, and it is well known to those skilled in the art that the covers mounted on the contents of wall-mounted electric dust boxes, TV amplifier boxes, fire hydrant boxes, etc. are all within the scope of the present invention. The technicians will know.

Applying the present invention, it is possible to prevent the phenomenon that the center portion of the door of the terminal box cover lifting (bending phenomenon). In other words, the door is smoothly closed to the frame of the cover not only to increase the reliability of the product, but also has the advantage of beautiful appearance.
