Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to the structure of a container used to house electronic components such as relays and fuses installed in automobiles, for example.

[Background of the idea]

As a conventional structure of this type of container, for example,
There is something like the one shown in the figure. This container 1 includes a housing member 3 made of synthetic resin for housing electronic components 2 such as relays and fuses, and this housing member 3.
It has a lower opening edge 5 that comes into contact with the upper opening edge 4, and a lid member 6 made of synthetic resin that is attached to the housing member 3, and further includes a lid member 6 made of synthetic resin that is attached to the housing member 3, A locking pawl 7 that connects to the lid member 6 is provided on the side surface, and a locking pawl 7 is provided on the lid member 6 to protrude downward from the lower opening edge 5 of the lid member 6 so that it can be locked with the locking pawl 7. After providing the locking tongue piece 8 and placing the lid member 6 on the housing member 3, the lid member 6 is fitted into the opening of the housing member 3 by locking the locking tongue piece 8 to the locking claw 7. It is removably attached.

However, in the case of the container 1 having such a conventional structure, the lid member 6 is placed over the storage member 3, and the locking claw 7 and the locking tongue piece 8 are locked to attach the lid member 6 to the storage member 3. When attached, a gap A is created between the opening edge 5 of the lid member 6 and the opening edge 4 of the housing member 3. It is desirable to design so that this gap A does not occur, but if this gap A is designed to be zero, the engagement between the locking pawl 7 and the locking tongue piece 8 will deteriorate, Furthermore, extremely high dimensional accuracy is required, resulting in high cost.

If the gap A occurs, the opening edge 5 of the lid member 6 and the opening edge 4 of the storage member 3 collide with each other due to the vibration of the container 1, causing a rattling sound (abnormal noise). Furthermore, there was a problem in that the locking claw 7 and the locking tongue 8 were disengaged due to the vibration.

[Purpose of invention]

The present invention has been developed by focusing on the problems of the conventional art. A triangular protrusion with an inclined surface that comes into elastic contact with the other opening edge in the thickness direction is provided, and the above-mentioned rattling noise can be reduced by utilizing the flexibility of these members in the thickness direction. The object of the present invention is to provide a container capable of suppressing the occurrence of this problem.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIGS. 1 to 3. The same parts between the structure of this embodiment and the structure shown in the conventional example will be designated by the reference numerals cited in the conventional example. The explanation of the same structure will be omitted.

That is, in this embodiment, the housing member 3 is smaller than the conventional example.
The difference is that a protrusion 9 is provided at a suitable position on the opening edge 4, and this protrusion 9 achieves the object of the present invention. The shape of the protrusion 9 is triangular in cross section, with the surface facing inward of the housing member 3 formed into an inclined surface 10 with a pointed top end, as shown in the figure. A plurality of locking pawls 7 are provided on the opening edge 4 of the opening edge 4 in correspondence with the locking pawls 7 described above.

Further, the opening edge 5 of the lid member 6 is provided with a notch 11 into which the projection 9 and the locking claw 7 can be locked.

When attaching the lid member 6 to the housing member 3 formed in this manner, the lid member 6 is positioned on the housing member 3 and the locking tongue piece 8 is locked by the locking claw 7. . At this time, since the inclined surface 10 of the protrusion 9 comes into contact with the outer corner 12 of the opening edge 5 of the lid member 6, the opening edges 4 and 5 of the lid member 6 and the housing member 3 are By being pressed elastically (see FIG. 1), rattling between the lid member 6 and the housing member 3 is prevented.

Further, due to the elastic contact force between the protrusion 9 and the outer corner 12 of the opening edge 5, the opening edge 5 of the lid member 6 is
The locking force between the locking pawl 7 and the locking tongue piece 8 is ensured because the pressing force is applied to the inner side and the opening edge 4 of the housing member 3 is applied to the outer side.
The engagement and retention of the housing member 3 and the lid member 6 is ensured.

As described above, according to this embodiment, the opening edge of the housing member 3 has a very simple structure in which the protrusion 9 having the inwardly inclined surface 10 is protruded, so that the engagement between the housing member 3 and the lid member 6 is achieved. This has the effect of eliminating the wobbling caused at times, and further ensuring the engagement between the housing member 3 and the lid member 6. In the above embodiment, the protrusion 9 for preventing rattling was provided protruding from the opening edge 4 of the housing member 3, but the invention is not limited to this, and the protrusion 9 may be provided protruding from the opening edge 5 of the lid member 6. good.

[Summary of the idea]

As described above, in the present invention, the lid member 6 that covers the housing member 3 is provided with the opening edge 5 that joins the opening edge 4 of the housing member 3, and the locking portions 7 and 8 that lock each other are provided on the housing member 3. 3. Provided on the lid member 6,
In the container that connects both members 3 and 6, at a suitable position on the edge of either one of the opening edges 4, 5,
A protrusion 9 is provided with an inclined surface 10 facing inward that contacts the other opening edge, and when the housing member 3 is closed with the lid member 6, the opening edge 5 and the outer corner 12 of the lid member are This container is characterized in that a notch 11 is provided on the other opening edge to serve as a relief part for the projection 9 which is pressed against the inclined surface of the projection 9 and is displaced by the contact pressure.

[Effect of idea]

Therefore, according to this container structure, when the lid member 6 is placed on the housing member 3 and the housing member 3 and the lid member 6 are attached by locking both the locking portions, the inclined surface 10 of the protrusion 9 is attached to the other side. Since it comes into contact with the outer corner 12 of the member and the opening edges of both members are pressed elastically in the thickness direction, no rattling occurs between the two members. Furthermore, the locking part 7
The locking force between and 8 is also ensured, and the connection between both members is also ensured, resulting in the following effects.
