Abstract

According to one embodiment, a connection device includes an engaging claw extending in a first direction from a first member, and a receiving portion provided in a second member. The engaging claw includes a pair of first side surfaces, and a pair of engaging protrusions projecting out from the respective side surface. Each engaging protrusion includes an inclined surface continuous from the first side surface and inclined to the first direction. The receiving portion includes a pair of slopes extending in the first direction and each including a second side surface engaging the first side surface, and an engaging projection connected to the second side surface, the engaging projection engaging the engaging protrusion.

First claim

What is claimed is:

1. A connection device comprising:
an engaging claw extending in a first direction from a cover;
the engaging claw comprising a pair of first side surfaces each extending in the first direction, and a pair of engaging protrusions provided in an extending end portion of the engaging claw and each projecting out from the respective first side surface in a direction intersecting the first direction, and
a housing comprising a side wall, a pair of slopes on the side wall, the pair of slopes extending in the first direction and each including a second side surface engaging the first side surface, and an engaging projection connected to the second side surface, the engaging projection engaging the engaging protrusion.

2. The connection device of claim 1 , wherein
an angle made between the first side surface of the engaging claw and the inclined surface is greater than 90°.

3. The connection device of claim 2 , wherein
the angle is 120° to 150°.

4. The connection device of claim 1 , wherein
the housing comprises a pair of slopes each including a guide surface extending to be inclined from the bottom surface towards the projecting end of the engaging projection along the first direction, and
an interval between the pair of slopes is greater than an interval between the pair of first side surfaces of the engaging claws and is less than an interval between the pair of engaging projections.

5. The connection device of claim 4 , wherein
the engaging claw comprises a first main surface intersecting the pair of first side surfaces and a second main surface opposing the first main surface.

6. The connection device of claim 5 , wherein
the engaging claw is formed of synthetic resin and is elastically deformable in a direction intersecting the first main surface.

7. The connection device of claim 5 , wherein
the engaging claw comprises a reinforcement rib provided to overlap the first main surface and the pair of the engaging protrusions.

8. The connection device of claim 1 , wherein
the engaging claw comprises a first main surface intersecting the pair of first side surfaces and a second main surface opposing the first main surface.

9. The connection device of claim 1 , wherein, each of the engaging projections comprises an engaging surface inclined to the first direction, the engaging surface engaging the inclined surface of the engaging protrusion.

10. The connection device of claim 1 , wherein, the engaging protrusions each comprises an inclined surface continuous from the first side surfaces and extending to be inclined to the first direction.
