The housing 110 is opened on one side, and a housing space for accommodating electronic components, a circuit board, and the like is formed therein. In the first embodiment of the present invention, a rectangular parallelepiped having one side opened is shown. The material of the housing 110 may be a metal material such as aluminum or a synthetic resin material. Even if a slight deformation is applied to the housing 110, the elasticity can be restored to a circular shape due to the characteristics of the material.

At least one first coupling structure 112 may be formed on the inner surface of the housing 110, for example, four as shown in the figure. In this embodiment, the first coupling structure 112 is installed at the end of a 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 a shape of a donut-tailed inverted trapezoid, a circle, a tee (T), or a rhombus. The first coupling structure 112 thus formed may be coupled in a sliding manner with the second coupling structure 122 formed on the lid 120 so that the housing 110 and the lid 120 are coupled.

1 and 2, the first coupling structure 112 includes a column-shaped protruding structure 111 (FIG. 1) protruding from an inner surface of the housing 110 by a predetermined length or more, ) Formed in the shape of a dovetail. At this time, the protruding structure 111 having a column shape protruding beyond a predetermined length can prevent the cover 120 from being inserted into the inside of the housing 110 by a predetermined depth or more even if the cover 120 is seated inside the side wall of the housing 110. This is for supporting the lid 120 when the size of the lid 120 is equal to or smaller than the size of the open surface of the housing 110.

The cover 120 is formed in a plate shape as shown in FIGS. 1 and 2, and has a second engagement structure 122, as described above. In this embodiment, since the coupling protrusion 112, which is the first coupling structure 112, is formed in a dovetail shape, the second coupling structure 122 is formed in a keyhole-like shape so that the dovetail shape of the coupling protrusion can be inserted and slidably engaged. Lt; / RTI >

As shown in FIG. 1, the key engagement groove is formed to include an inlet having a size to which a dovetail shape can be inserted, and a portion that is slidably engaged with the dovetail shape. 1 and 2, the left portion of the second coupling structure 122 corresponds to the entrance where the dovetail shape is inserted, and when the sliding coupling is completed corresponding to the right-handed portion, the first coupling structure 112 Is engaged with a portion of the second joining structure 122 where the joining imaginary line (one-dot chain line) ends.

2, the size of the lid 120 is such that when the first engagement structure 112 and the second engagement structure 122 are engaged, the circumference of the lid 120 and the inner surface of the side wall of the housing 110 And may be formed to have the same size as that of the housing 110 so as to face the side face. At least a portion of the circumference of the cover 120 located behind the sliding direction may be formed to face an inner surface of the corresponding portion of the sidewall of the housing 110. This is a structure for preventing the lid from moving backward in the opposite direction of sliding in a state where the first engagement structure 112 and the second engagement structure 122 are slidably engaged without a separate stopper.

3, the electronic device case 200 according to the second embodiment includes a first coupling structure 212 provided at an end of a column-shaped protruding structure 211, Is formed as a keyhole-shaped coupling groove, and the corresponding second coupling structure 222 has a dovetail-shaped coupling protrusion. The description of the remaining parts of the housing 210 and the lid 220 is the same as in the first embodiment and therefore will be omitted.

FIGS. 4 and 5 illustrate a third embodiment of the present invention. In the electronic device case 300 according to the third embodiment, the housing 310 is the same as the first embodiment, and the circuit board 320 is coupled to the housing 310. To this end, the first coupling structure 312 formed in the housing 310 is formed on the protruding structure 311 of a lower height than that formed in the first embodiment.
