SUMMARY OF THE INVENTION According to the present invention, an electronic component storage portion in which a plurality of recesses for storing electronic components are formed and a peripheral portion of the electronic component storage portion hangs down so as to surround the electronic component storage portion. A lower case having an outer peripheral wall, and a top plate that overlaps the upper surface of the lower case and covers the electronic component storage portion of the lower case, and an outer periphery that hangs from the peripheral edge of the top plate so as to surround the outer peripheral wall of the lower case. An upper case having a wall, and a case for storing electronic components, wherein the lower case and the upper case have outer peripheral walls formed with a plurality of protrusions protruding toward the outside of the case so as to overlap each other. Since the protrusions that overlap each other are formed on the outer peripheral walls of the lower case and the upper case, the rigidity of the outer peripheral walls of the lower case and the upper case is high. The outer peripheral wall even dropped while the casing vertically will not cause deformation as to reach the recess for accommodating the electronic component.

Further, the present invention is characterized in that a gap is formed between a tip of a protrusion formed on an outer peripheral wall of the lower case and a tip of a protrusion formed on an outer peripheral wall of the upper case. Thus, for example, when the case is dropped vertically, the impact of the drop is mainly applied to the protrusions formed on the upper case, and the lower case having the electronic part storage part for storing the electronic parts is provided. Is rarely applied.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of an electronic component storage case of the present invention, and FIG. 2 is a sectional view of the electronic component storage case.

As shown in FIGS. 1 and 2, the electronic component storage case of the present invention is made of a resin such as polystyrene resin and is formed by a vacuum molding method or the like, a lower case 1 and an upper case 2. It consists of and.

The lower case 1 acts as a support member for supporting the electronic component 3, and an electronic component storage portion 4 in which a plurality of recesses 4a for accommodating the electronic component are arranged is formed on the upper surface thereof. The electronic component 3 is housed inside each recess 4a of the housing portion 4.

In the lower case 1, a frame-shaped outer peripheral wall 5 is hung so as to surround the electronic component accommodating portion 4 from the periphery of the electronic component accommodating portion 4, and the outer peripheral wall 5 accommodates the electronic component. The electronic component 3 housed in the portion 4 is protected from an external impact.

On the other hand, the upper case 2 acts as a lid for preventing the electronic component 3 housed in the recess 4a of the electronic component housing 4 of the lower case 1 from jumping out from the recess 4a. A top plate 6 that covers the electronic component storage portion 4 of the lower case 1 and an outer peripheral wall 7 that hangs from the peripheral edge of the top plate 6 so as to surround the outer peripheral wall 5 of the lower case 1.
The top plate 6 serves to prevent the electronic component 3 housed in the recess 4a of the lower case 1 from jumping out of the recess 4a, and the outer peripheral wall 7 is provided on the lower case 1 and the upper case 2 respectively.
And the electronic parts storage section 4 of the lower case 1
The electronic component 3 accommodated in the above is protected from an external impact.

Further, the lower case 1 and the upper case 2 have projecting portions 5a, 7a projecting on a part of each side of the outer peripheral walls 5 and 7 so as to overlap each other toward the outside of the case.
Is formed plurally, and the rigidity of each side of the outer peripheral walls 5 and 7 is high due to the protrusions 5a and 7a. For example, when an impact force is applied to the outer peripheral walls 5 and 7 when the case is dropped. Also, the outer peripheral walls 5 and 7 are concave portions 4a for accommodating the electronic components 3.
Therefore, the electronic component 3 housed inside the recess 4a is not deformed or damaged.

In the case for storing electronic parts, the protrusion amount of the protrusion 5a formed on the outer peripheral wall 5 of the lower case 1 is smaller than the protrusion amount of the protrusion 7a formed on the outer peripheral wall 7 of the upper case 2. It is assumed that a gap G is formed between the tip of the protrusion 5a formed on the outer peripheral wall 5 of the lower case 1 and the tip of the protrusion 7a formed on the outer peripheral wall 7 of the upper case 2. Then, even if a shock is applied to the outer peripheral wall 7 of the upper case 2 when it is dropped, the shock is blocked by the gap G, and is almost never applied to the lower case 1 housing the electronic component 3. Therefore, the electronic component 3 housed inside can be protected more firmly. Therefore, in the electronic component storage case, a gap G is formed between the tip of the protrusion 5a formed on the outer peripheral wall 5 of the lower case 1 and the tip of the protrusion 7a formed on the outer peripheral wall 7 of the upper case 2. Preferably.

Thus, according to the electronic component storage case of the present invention, the electronic component 3 is stored in the recess 4a of the electronic component storage portion 4 of the lower case 1, and the upper case 2 is covered on the upper surface of the lower case 1. By fastening the lower case 1 and the upper case 2 with a rubber band, cellophane tape or other fastening means, the electronic component 3 is housed inside the electronic component housing case composed of the lower case 1 and the upper case 2. .

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the above-mentioned embodiment, the lower case 1 is used. Although the polystyrene resin is exemplified as the resin material forming the upper case 2, the resin material forming the lower case 1 and the upper case 2 may be, for example, a polyvinyl chloride resin, a polyolefin resin, or a polyester in addition to the polystyrene resin. Other resins such as resin, modified polyphenylene oxide resin, polyether sulfone resin, polysulfone resin, polyphenylene sulfide resin, phenol resin, epoxy resin may be adopted, and further, these resins may be powdered or fibrous. Is a mixture of scale-like inorganic insulator, metal, organic filler, antistatic agent, and colorant It may be employed.

Further, in the above-mentioned embodiment, the vacuum forming method is exemplified as the forming method of the lower case 1 and the upper case 2, but the forming method of the lower case 1 and the upper case 2 is other than the vacuum forming method. A molding method such as an injection molding method, a transfer molding method, a press molding method, or a blow molding method can be adopted.
