Abstract

An electronic device includes: a case including a wall portion including an opening, and a pair of longitudinal grooves, wherein each of the longitudinal grooves includes a first groove portion that is disposed with the opening between the first groove portions; a second groove portion that is contiguous to the first groove portion through an inclined groove wall; a lid that moves along the longitudinal grooves, and that is brought closer to the wall portion by the inclined groove wall under an action of moving the lid to the first groove portion; a resilient member that is provided at the lid, and that is compressed by the wall portion and the lid by the action of moving the lid closer to the wall portion; and a connection member that is connected to an electronic component inside the case, and that is exposed from the opening when the opening is opened.

First claim

What is claimed is:

1. An electronic device comprising:
a case including
a wall portion including an opening, and
a pair of longitudinal grooves extending along a side face of the wall portion,

wherein
each of the longitudinal grooves includes
a first groove portion that is disposed with the opening between the first groove portions;
a second groove portion that is disposed at a position separated from the opening and is contiguous to the first groove portion through an inclined groove wall;

a lid that moves along the longitudinal grooves, and that is brought closer to the wall portion by the inclined groove wall under an action of moving the lid to the first groove portion;
a resilient member that is provided at the lid, and that is compressed by the wall portion and the lid at the periphery of the opening by the action of moving the lid closer to the wall portion; and
a connection member that is electrically connected to an electronic component inside the case, and that is exposed from the opening when the opening is opened.

2. The electronic device of claim 1 , wherein each of the longitudinal grooves further includes a wide width groove portion that has a greater groove width than the groove widths of the first groove portion and the second groove portion and that is formed with the inclined groove wall.

3. The electronic device of claim 1 , wherein:
the lid includes a projection that moves inside the longitudinal groove; and
the lid is brought closer to the wall portion under an action of moving the projection to the first groove portion.

4. The electronic device of claim 3 , wherein:
the projection includes a first projection that moves inside the longitudinal groove, and a second projection that is provided separated from the first projection and moves inside the longitudinal groove.

5. The electronic device of claim 4 , wherein an overall length of the first groove portion is a length from an outer end of the first projection to an outer end of the second projection, or greater.

6. The electronic device of claim 4 , wherein a face on the wall portion side of the first projection and a face on the wall portion side of the second projection are in the same plane as each other.

7. The electronic device of claim 4 , wherein:
a thickness of the first projection is a thickness so as to engage with the first groove portion and the second groove portion; and
a third groove portion of smaller groove width than the groove width of the first groove portion is formed to the first groove portion at a terminal end of the first groove portion on an opposite side to the wide width groove portion side.

8. The electronic device of claim 7 , wherein:
an overall length of the third groove portion is a length of the second projection or greater.

9. The electronic device of claim 7 , wherein:
the inclined groove wall is formed at a connection portion between the first groove portion and the second groove portion;
a first inclined face is formed at a connection portion between the first groove portion and the third groove portion; and
the first projection and the second projection are configured as plate tabs, and a second inclined face is formed at the first projection and the second projection along a direction of the inclined groove wall and the first inclined face.

10. The electronic device of claim 4 , wherein:
the resilient member is disposed inside a region corresponding to from an outer end of the first projection to an outer end of the second projection.

11. The electronic device of claim 2 , wherein:
a wall face on the wall portion side of the first groove portion and a wall face on the wall portion side of the wide width groove portion are in the same plane as each other; and
a wall face of the second groove portion on the opposite side to the wall portion side and a wall face of the wide width groove portion on the opposite side to the wall portion side are in the same plane as each other.

12. The electronic device of claim 1 , wherein a covering portion, that covers a portion of the lid in an open state in which the opening is opened, is provided to the case.

13. The electronic device of claim 2 , wherein a length of the lid is a length so as to cover the wide width groove portion in a closed state in which the opening is closed.

14. The electronic device of claim 1 , wherein:
a protrusion portion that protrudes in an intersecting direction that intersects with the protrusion direction of the projection is formed at the lid; and
a contact portion is provided to the case so as to be disposed with a separation from the wall portion and so as to make contact with the protrusion portion in a closed state in which the opening is closed.

15. The electronic device of claim 1 , wherein the resilient member includes:
a fixed portion that is fixed to the lid; and
a peripheral edge portion that protrudes from a peripheral edge of the fixed portion further to the wall portion side than the fixed portion.
