(Configuration of embodiment)
Referring to FIG. 1, housing 100 of the present invention has rear cover 10 and upper cover 20 as a pair of covers. The housing 100 fixes and accommodates a substrate 30 as a member to be fixed between a pair of covers. That is, the housing 100 fixes and accommodates the board 30 between the rear cover 10 and the upper cover 20 .

The rear cover 10 is an example of one of the pair of covers. Rear cover 10 includes a support portion 11 and a claw portion 12 .

The support portion 11 is erected on the inner surface of one of the pair of covers and supports the member to be fixed. Specifically, the support portion 11 is erected on the inner surface of the rear cover 10 and supports the substrate 30 at a position spaced apart from the inner surface of the rear cover 10 . Although two supporting portions 11 are shown in FIG. 1, the number may be one or three or more.

The claw portion 12 is erected on the inner surface of one of the pair of covers, and protrudes through an opening (hole portion 31) provided in the member to be fixed. Specifically, the claw portion 12 is erected on the inner surface of the rear cover 10 and protrudes through a hole portion 31 provided in the substrate 30 .

The upper cover 20 is an example of the other cover of the pair of covers. Upper cover 20 includes pins 21 .

The pin 21 is erected on the inner surface of the other cover of the pair of covers, and engages with the claw portion 12 while the inner surfaces of the pair of covers face each other. Specifically, the pin 21 is erected on the inner surface of the upper cover 20 and engages with the claw portion 12 of the rear cover 10 when the inner surfaces of the rear cover 10 and the upper cover 20 face each other.

The plurality of support portions 11 of the rear cover 10 are columnar or tubular bosses, and stand on the inner surface of the rear cover 10 . The plurality of support portions 11 of the rear cover 10 support the substrate 30 at positions spaced apart from the inner surface of the rear cover 10 . In other words, the plurality of support portions 11 of the rear cover 10 support the member to be fixed from below while floating from the inner surface of the rear cover 10 . FIG. 1 shows, as an example, a state in which two support portions 11 are erected.

The claw portion 12 of the rear cover 10 shown in FIG. 1 is arranged at a position between the plurality of support portions 11 . The claw portion 12 of the rear cover 10 includes a pair of elastically deformable locking claws having hook portions at their ends. The pair of locking claws has a substantially conical shape, a substantially pyramidal shape, a substantially truncated conical shape, or a substantially truncated pyramidal shape as a whole, and has a tapered surface on its surface. When the hole portion 31 of the substrate 30 is pushed from above the tapered surfaces of the pair of locking claws, the pair of locking claws are elastically deformed so as to narrow the distance from each other, and the hole portion 31 of the substrate 30 climbs over the hook portion. At this point, the pair of locking pawls returns to its original state.

In this manner, the substrate 30 is fixed between the top surface of the plurality of support portions 11 of the rear cover 10 and the hook portions of the claw portions 12 of the rear cover 10, and the substrate 30 is lifted from the inner surface of the rear cover 10. 30 is fixed.

As described above, the member to be fixed by the housing method according to the embodiment of the present invention is, for example, the substrate 30 having the hole 31 as an example of the opening shown in FIG. The substrate 30 is an example of a member to be fixed, and is a plate-shaped member in FIG.

2A to 2C show the appearance of a housing configured by combining the rear cover 10 and the upper cover 20. FIG. In FIGS. 2A to 2C, the outline of the substrate 30 fixed between the rear cover 10 and the upper cover 20 is indicated by dotted lines. FIG. 2A shows a mode in which the upper cover 20 is provided with a display section and an operation section.

(Operation of embodiment)
Next, as the operation of the embodiment of the present invention, the procedure for assembling the housing of the embodiment of the present invention and the fixation of the member to be fixed (substrate 30) will be described.

Referring to FIG. 4, first, the rear cover 10 is placed on the floor, for example, and the board 30 is incorporated into the rear cover 10 from above. At this time, the hole portions 31 of the substrate 30 are pushed into the claw portions 12 of the rear cover 10 to assemble. Then, the elastically deformable claw portion 12 deforms inward along the hole portion 31 of the substrate 30, and when the substrate 30 reaches the lower side of the claw portion 12, the claw portion 12 returns to its original shape. In other words, the pair of locking claws is elastically deformed so as to narrow the gap between the pair of locking claws. return. As a result, the substrate 30 is fixed inside the housing 100 at positions between the top surfaces of the plurality of support portions 11 of the rear cover 10 and the hook portions of the claw portions 12 of the rear cover 10 . The pair of locking claws is included in the claw portion 12 and has a hook portion at its tip.

In this state, the board 30 is generally fixed to the rear cover 10 by the claw portions 12 and the support portions 11 of the rear cover 10 . This fixation is sufficiently stable under normal conditions, but when an external impact is applied, the claw portions 12 of the rear cover 10 are deformed inward, the fixed state is released, and the substrate 30 is disengaged. It is also possible that they may fall off. Therefore, the upper cover 20 is further combined with the rear cover 10 , and the pins 21 of the upper cover 20 are inserted between the pair of claw portions 12 of the rear cover 10 . By doing so, the claw portion 12 of the rear cover 10 is prevented from being deformed inward, the substrate 30 is prevented from coming off, and internal parts such as the substrate 30 are securely fixed between the upper cover 20 and the rear cover 10. .

(Effect of Embodiment)
The housing according to this embodiment has the following effects.

A first effect is that the member to be fixed can be stably fixed to either one of the pair of covers without preparing a separate part other than the pair of covers, such as fixing screws. This is because the member to be fixed is fixed between the top surfaces of the plurality of support portions 11 of the rear cover 10 and the hook portions of the claw portions 12 of the rear cover 10 . Further, by combining the upper cover 20 with the rear cover 10 and inserting the pins 21 of the upper cover 20 between the pair of claw portions 12 of the rear cover 10, the upper cover 20 and the rear cover 10 can be securely connected. This is because the member to be fixed is fixed. This eliminates the need for screw fixing, and only a pair of covers such as upper and lower covers are required for fixing.

A second effect is that the assembling method is simple. Since the supporting portion 11 and the claw portion 12 are erected on one cover, the elastically deformable claw portion 12 is pushed into the hole portion of the substrate 30 by pushing the hole portion 31 of the substrate 30 into the claw portion 12 . 31, and when the substrate 30 reaches the lower side of the claw portion 12, the claw portion 12 returns to its original shape, and the substrate 30 can be fixed to one cover. Further, in this embodiment, the assembly is realized by pressing and moving only in the vertical direction perpendicular to the inner surface of one cover without having a complicated hook shape. Further, when the upper cover 20 is combined with the rear cover 10 to form a housing, the tip of the pin 21 provided upright on the inner surface of the upper cover 20 engages with the claw portion 12 of the rear cover 10, and the claw portion of the rear cover 10 is engaged. 12 and the hole portion 31 of the substrate 30 can be maintained more stably. Further, when the claw portions 12 are arranged between the plurality of supporting portions 11, the substrate 30 to be fixed can be stably fixed both in the horizontal direction and the vertical direction of the main surface thereof. can.

A third effect is that cost reduction can be expected. This is because the members to be fixed such as the substrate 30 can be fixed by the functions of the supporting portions 11, the claw portions 12, the pins 21, and the like integrally arranged on the inner surfaces of the covers constituting the pair of covers. As described above, screw fixation is unnecessary, and the only parts required for fixation are the upper and lower covers, so a significant reduction in parts cost is expected.

A fourth effect is that the member to be fixed can be fixed without damaging the peripheral portion or side end face of the member to be fixed. In this embodiment, a supporting portion 11 and a claw portion 12 are provided on one cover, and the internal component is fixed by engaging the claw portion 12 with a hole provided in the internal component to be fixed. This is because the member to be fixed can be fixed without contacting the peripheral portion or the side end surface of the fixing member.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto. For example, although FIG. 1 and FIG. 3 show the case where there are two supporting portions 11, the number of supporting portions 11 erected on the rear cover 10 is not limited to two, and three or more may be erected. good. 1 and 3 show the case where the claw portion 12 including a pair of locking claws is provided at one location, but the location at which the claw portion 12 is provided is not limited to one location, and two or more claws may be provided. A portion may be provided to fix the member to be fixed. 1 and 4 show the case where the claw portion 12 of the rear cover 10 includes two locking claws, but the number of locking claws constituting the claw portion 12 is not limited to two. It may consist of one or more. For example, the substantially cone-shaped, substantially pyramid-shaped, substantially truncated cone-shaped, or substantially truncated-pyramid-shaped locking claws included in the claw portion 12 are divided into three or four, and three locking claws are included in the claw portion 12. Alternatively, the claw portion 12 may include four locking claws. It can be appropriately selected in consideration of the ease of manufacturing the shape of the claw portion 12 of the rear cover 10, the stability of fixing the parts against impact, and the like. Various modifications are possible within the scope of the invention described in the claims, and it goes without saying that they are also included in the scope of the present invention.
