In the first embodiment of the present invention it is shown that one surface is formed in an open rectangular parallelepiped shape. The material of the housing 110 may be made of a metal material such as aluminum or a synthetic resin material. Through this, even if a slight deformation is applied to the housing 110, it may have elasticity that is restored to its original shape due to the characteristics of the material.

At least one first coupling structure 112 may be formed on an inner side surface of the housing 110, for example, four may be formed as shown in the drawing. In the present embodiment, the first coupling structure 112 is installed at the end of the column-shaped protruding structure 111 protruding from the bottom surface of the housing by a predetermined length or more. The first coupling structure 112 may be formed in any one of an inverted trapezoidal shape having a dove tail shape, a circular shape, a tee shape, and a rhombus shape. The first coupling structure 112 formed as described above may be coupled to the second coupling structure 122 formed on the cover 120 in a slide manner so that the housing 110 and the cover 120 are coupled to each other.

That is, in the present embodiment, as shown in FIGS. 1 and 2, the first coupling structure 112 has a columnar protrusion structure 111 protruding beyond a predetermined length from the inner surface of the housing 110. ) Is a coupling protrusion formed in the shape of a dovetail at the end. At this time, the column-shaped protruding structure 111 protruding beyond a predetermined length may serve to prevent the cover 120 from being inserted more than a predetermined depth inside even when the cover 120 is seated inside the side wall of the housing 110. This is to support the cover 120 when the size of the cover 120 is the same as or smaller than the size of the open surface of the housing 110.

1 and 2, the cover 120 is formed in a plate shape, and as described above, has a second coupling structure 122. In the present embodiment, as the coupling protrusion, which is the first coupling structure 112, is formed in a dovetail shape, the second coupling structure 122 has a keyhole-shaped coupling groove so that the dovetail shape of the coupling protrusion can be inserted and slide-coupled.

At least a portion of the circumference of the cover 120 that is located at the rear side with respect to the sliding direction may be formed to face an inner side surface of the sidewall of the housing 110 corresponding thereto. This is a structure for preventing the cover from being separated back by sliding backwards in the opposite direction in the state in which the first coupling structure 112 and the second coupling structure 122 are slidingly coupled without a separate stopper.

3 is a view showing a second embodiment of another embodiment of the present invention, in which the electronic device case 200 according to the second embodiment of the present invention has a first coupling structure 212 installed at an end of a column-shaped protruding structure 211. ) Is formed as a keyhole-shaped coupling groove, and the dovetail-type coupling protrusion is formed in the second coupling structure 222 corresponding thereto. Descriptions of the rest of the housing 210 and the cover 220 are the same as in the first embodiment, and thus will be omitted.

This is to accommodate the circuit board 320 in the accommodation space inside the housing 310. Therefore, as shown in FIG. 5, the height of the protruding structure 311 is formed to be lower than the depth of the receiving space of the housing 310.

In addition, the size of the circuit board 320 may be formed to have a small size to be accommodated in the accommodation space of the housing 310. However, due to this, the first coupling structure 312 and the second coupling structure 322 formed on the circuit board 320 are coupled, and then the first coupling structure 312 and the second coupling structure 322 due to external impact or the like. ), There is a risk that the coupling may be separated.
