Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing the vicinity of the front panel of the housing of the present invention.

The front panel 30 is composed of a decorative plate 31 formed by molding plastic and an elastic metal plate 32, and the metal plate 32 is provided with four latching levers 33. A hook portion 33a bent inward is formed at the tip of the latch lever 33. The latch lever 33 is a metal plate 32.
Although it can be formed by bending, it may be fixed by caulking an elastic latching lever 33 to the metal plate 32 as shown in FIG. 2, or by welding. Here, since the metal plate 32 is disposed on the inner surface side of the front panel 30, the electromagnetic wave shielding property is improved as compared with the one formed of only plastic.

Further, a hooking hole 41a is opened in the side panel portion 41 of the base panel 40, and the hooking lever 33 has a hook portion 3a.
The base panel 40 is hooked by inserting 3a into the hooking hole 41a.
Further, as shown in FIG. 3, the side panel 41 of the base panel 40 is provided with a latch lever 42, and the metal plate 32 of the front panel 30 is provided with a latch hole 32a. 32a may be hooked.

FIG. 4 is an exploded perspective view showing the vicinity of the rear panel of the housing of this embodiment.

The back panel 50 is formed by bending a metal plate having elasticity and has four latching levers 51 similar to those of the front panel 30. Further, the side panel portion 41 has a latch hole 41a which is latched by the latch lever 51.

When assembling the housing of this embodiment, the latch lever 33 is attached to the side panel 41 as shown in FIGS. 5 (a) and 5 (b).
When the front panel 30 is pressed against the base panel 40 along the outer surface of the, the latch lever 33 elastically deforms outward. Then, when the latch lever 35 reaches a predetermined position, as shown in FIG.
As shown in (c), the hook lever 33 restores its original shape so that the hook portion 33a is inserted into the hook hole 41a, and the base panel 40 is hooked. Next, the latching hole 51a of the base panel 40 is also latched by the latching lever 51 of the rear panel 50. As a result, the front panel 30 and the rear panel 50 are temporarily fixed to the base panel 40, respectively.

FIG. 6 is a plan sectional view of the storage case of this embodiment.

The outer cover 60 has a substantially U-shaped cross section, and is fitted into the base panel 40 to which the front panel 30 and the rear panel 50 are temporarily fixed from the rear side. When the outer cover 60 reaches the fixed position, the front end surface of the outer cover 60 is pressed against the front panel 30 without a gap as shown in FIG. This prevents the front panel 30 from moving due to rattling with the base panel 40. Further, the exterior cover 60 is fixed to the base panel 40 by the screw 8, and at this time, the rear panel 50 is also fixed by the common screw 8 together with the exterior cover 60.

At the fixed position, the inner surface of the exterior cover 60 abuts the latch lever 33 of the front panel 30 and the latch lever 51 of the rear panel 50. This prevents the latch lever 33 and the latch lever 51 from being deformed in the direction in which they are pulled out of the latch hole 41a, and even when an unreasonable force is applied to the front panel 30 or the rear panel 50 by mistake. The front panel 30 or the rear panel 50 is prevented from falling off.

Bent portions 62, which are substantially parallel to the one side panel portion 41, are formed at both end portions of the exterior cover 60, and the front end surface and the rear end surface of the pair of bent portions 62 respectively project forward. The protrusions 62a and 62b are formed. The front panel 30 also includes a pair of upper and lower L-shaped guide portions 34.
Is formed by bending a part of the metal plate 32, and from the side end surface of the rear panel 50, a pair of upper and lower flat plate-shaped guide portions 52 are formed.
Is protruding.

When the exterior cover 60 is fitted and inserted in the fixed position, the pair of protrusions 62a are fitted and inserted between the pair of guide portions 34 and held by the pair of guide portions 34 from above and below, as shown in FIG. Similarly to the protrusion 62a, the pair of protrusions 62b are also fitted between the pair of guide portions 52 and held by the pair of guide portions 52 from above and below. This prevents the outer cover 60 from being deformed so that the pair of bent portions 62 expands in the arrow direction shown in FIG.
Even if the number of screws 8 required for fixing to 40 is reduced, the outer cover 60 can be securely fixed without rattling.

In addition, the metal plate 32 of the front panel 30 is shown in FIG.
5, a pair of upper and lower urging plates 35 projecting inside the housing are formed, and a pair of upper and lower urging plates 53 protruding inside the housing are also formed on the rear panel 50 as shown in FIG. Has been done. These urging plates 35 and 53 have elasticity and are formed in a substantially V shape.

With the outer cover 60 fixed to the base panel 40, as shown in the side sectional view of FIG.
35 and 53 are pressed against the inner surface of the base panel 40, and the upper biasing plate 3
5, 53 are pressed against the inner surface of the outer cover 60. As a result, the front end portion of the outer cover 60 is pressed and held by the guide portion 34 and the urging plate 35 of the front panel 30, and the rear end portion of the outer cover 60 is connected to the guide portion 52 and the urging plate 53 of the rear panel 50. Is held under pressure. The outer cover 60 is reinforced by being pressed and held by the guide portions 34, 52 and the biasing plates 35, 53, so that the outer cover 60 can be prevented from being deformed and the base panel 40. Since the front panel 30, the rear panel 50, and the exterior cover 60 are surely grounded to each other, the electromagnetic shielding of the housing can be improved.
