Abstract

A retention device includes a holder and an extractable casing mounted to the holder. The retention device includes a base, a cover opposite to the base, and a lateral plate extending from the base and interconnecting the base and the cover. The base, the side plates, and the cover cooperatively define a rectangular first cavity with an opening at a lateral side. The casing and the holder cooperatively define a second cavity. A size of the second cavity is less than that of the first cavity.

Claims

1. A retention device comprising:

a holder comprising a base, a cover opposite to the base, and a lateral plate interconnecting the base and the cover, wherein the base, the side plates, and the cover cooperatively define a first cavity with an opening at a lateral side of the holder; and

an extractable casing mounted to the holder through the opening, the casing and the holder cooperatively defining a second cavity, a size of the second cavity being smaller than that of the first cavity.

2. The retention device of claim 1, wherein the casing comprises a bottom plate, a first side wall and a second side wall extending from two opposite lateral sides of the bottom plate, a third side wall extending from the bottom plate and interconnecting the first side wall and the second side wall, and a first notch defined in an area where the first side wall joins the third side wall, the first notch engaging with the holder to define the second cavity.

3. The retention device of claim 2, wherein the undercut is rectangular and defined by a first side plate, a second side plate, and a top plate.

4. The retention device of claim 3, wherein the first side plate of the undercut is substantially parallel to the third side wall of the casing, the second side plate of the undercut is substantially parallel to the first side wall of the casing, and the top plate of the undercut is substantially parallel to the bottom plate of the casing.

5. The retention device of claim 1, further comprising a side cover pivotably connected with the holder and covering the opening of the holder.

6. The retention device of claim 5, wherein the side cover comprises a slidable latch thereon, a projection is arranged at the cover of the holder, and the projection engages with the latch to fix the side cover on the holder.

7. The retention device of claim 6, wherein the latch is U-shaped.

8. The retention device of claim 6, wherein the latch defines a notch at a top potion thereof, a tab extends out form the latch to semi-close the notch, and the projection engages with the tab of the latch.

9. An electronic device, comprising:

a retention device comprising;

a holder comprising a base, a cover opposite to the base, and a lateral plate extending from the base and interconnecting the base and the cover, wherein the base, the side plates, and the cover cooperatively define a rectangular first cavity with an opening at a lateral side of the cavity;

an extractable casing mounted to the holder, the casing and the holder cooperatively defining a second cavity, a size of the second cavity being smaller than that of the first cavity; and

a storage module selectively fixed in the first cavity and the second cavity of the retention device.

10. The electronic device of claim 9, wherein the casing comprises a bottom plate, a first side wall and a second side wall extending from two opposite lateral sides of the bottom plate, a third side wall extending from the bottom plate and interconnecting the first side wall and the second side wall, and a first notch being defined in an area where the first side wall joins the third side wall, the first notch engaging with the holder to define the second cavity.

11. The electronic device of claim 10, wherein the undercut is rectangular and defined by a first side plate, a second side plate, and a top plate.

12. The retention device of claim 11, wherein the first side plate of the undercut is substantially parallel to the third side wall of the casing, the second side plate of the undercut is substantially parallel to the first side wall of the casing, and the top plate of the undercut is substantially parallel to the bottom plate of the casing.

13. A retention device for supporting a storage device, the retention device comprising:

a holder defining a first cavity therein and an opening at a lateral side of the holder;

a casing detachably mounted in the first cavity of the holder through the opening, the casing defining a second cavity less than that of the first cavity; and

a cover rotatably connected to the holder for covering the opening.
