Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a container for storing electronic components used, for example, in automobile wire harnesses.

[Conventional technology]

Examples of conventional containers for storing electronic components include those shown in FIGS. 4 and 5. This is provided with locking claws 3 on both end faces of a body member 2 that stores electronic components 1 inside, and a lid member 4 for waterproofing and dustproofing at the upper opening of this body part 2. is now being covered. This lid member 4
Lock arms 5 are provided on both sides of the
The upper opening of the body part 2 is closed by being locked by a locking claw 3 provided on the body part 2. In addition, the lower opening of the body member 2 is also waterproof.
A dustproof bottom cover 5 is locked to the body member 2 by the engagement between a lock arm 7 provided on the bottom cover 6 and a locking pawl 6 provided on the body member 2. Further, a drain hole 9 is provided on the bottom surface of the bottom cover 6, as shown in FIG. Reference numeral 10 denotes a perforation formed around the body part 2, and when the opening edge of the lid member 4 comes into contact with the protrusion 10, the body member 2
The opening edge of the lid member 4 is configured not to come into contact with the top plate of the lid member 4. 11 is an outlet for a lead wire 12 connected to an electronic component.

[Problem that the invention aims to solve]

However, in the case of such a conventional container for storing electronic components, the shape is such that there is no large gap between the lid member 4 and the body member 2, in order to prevent moisture from entering from the upper part. Because of the settings, when the electronic component 1 housed in the body member 2 generates heat due to its operation (energization), this heat is trapped inside the container, and this causes the electronic component to There was a problem that the performance and life of the product were adversely affected.

Further, although a drain hole 9 is formed in the bottom surface of the bottom cover 6, the exhaust effect of the drain hole 9 cannot be expected because the drain hole 9 is located at the bottom surface.

[Means to solve the problem]

The present invention has been devised by focusing on such conventional problems, and by forming a vertically penetrating gap between the lid member and the body member, the gap between the lid member and the body member is
To provide a storage container for electronic parts that can effectively discharge hot air inside the container by a synergistic action with a drain hole.

〔Example〕

The present invention will be explained in detail below based on the embodiment shown in Figs. , and the explanation of the same structural parts will be omitted.

That is, in this embodiment, the shape of the lid member 20 is different from that of the conventional example, but the other structure is the same as that of the conventional example.

In the embodiment shown in FIGS. 1 and 2, a passage 21 is provided at a corner of the side wall surface of the lid member 20 having the lock arm 5, which communicates the inside and outside between the lid member 20 and the body member 2. A projecting portion 22 is formed in order to form this structure.

Therefore, according to this embodiment, the passage 21 for ventilation is formed between the lid member 20 and the body member 2 by the projecting portion provided on the lid member 20. As a result, hot air generated within the container is immediately discharged to the outside, and electronic components within the container can be protected from heat.

Further, in the embodiment shown in FIG. 3, two protruding portions 22 similar to those described above are formed on each side wall surface of the lid member 20 that does not have the lock arm 5. (It may be one strip.) In this embodiment, in order to prevent the opening area of the passage 21 formed by the projecting portion 22 from being pinched, the body member 2 is A notch 10' is formed at a position corresponding to the protruding portion 22 of the protrusion 10 provided.

[Effect of idea]

This device is as described above, and a protrusion 10 is provided on the outside of the opening of the body member 2 at a distance from the opening edge and extends along the opening edge, and the lid is deeper than the spacing. In the container, which is closed by placing the member 20 over the opening of the body member 2 so that the edge of the opening of the lid member 20 comes into contact with the protrusion 10, the body member 2 of the lid member 20 is closed.
One end is attached to the part corresponding to the opening of the body member 2.
Since the projecting part 22 is provided to form a passageway that communicates with the inside of the container and the other end communicates with the outside, the passageway 21 effectively exhausts the hot air generated from the electronic components inside the container to the outside. As a result, the performance and life of the electronic components inside the container can be maintained under favorable conditions.

Claims (1)

[Scope of utility model registration request] A protrusion 10 is provided on the outside of the opening of the body member 2 at a distance from the opening edge and extends along the opening edge, and the lid member 20, which is deeper than the distance, is attached to the opening of the body member 2. In a container that is closed by the opening edge of the lid member 20 coming into contact with the protrusion 10, one end is placed on a portion of the lid member 20 corresponding to the opening of the body member 2. A container characterized by being provided with an overhang 22 forming a passageway communicating with the inside of the body member 2 and the other end communicating with the outside.
