Expansion device and Anti-slip bracket thereof

Abstract

An expansion device includes a backplate, a circuit board arranged parallel to the backplate, and an anti-drop bracket. The circuit board includes a base and an electrical connection portion protruding downward from a bottom edge of the base. The electrical connection portion is for insertion into an expansion slot. The anti-drop bracket includes a connector for mounting on the backplate and a hook plate connected to and located below the connector. When the connector is mounted on the backplate and the electrical connection portion of the circuit board is inserted into the expansion slot, the hook plate is engaged by a latch in the expansion slot.

Claims

1. An expansion device, comprising: A backplate; a circuit board, parallel to the backplate, including a base and an electrical connection portion protruding downward from a bottom edge of the base, the electrical connection portion being inserted into an expansion slot; and an anti-drop bracket, including a connector for mounting on the backplate and a hook plate connected to the connector and located below the connector, wherein when the connector is mounted on the backplate and the electrical connection portion of the circuit board is inserted into the expansion slot, the hook plate can be locked by a latch of the expansion slot, the connector of the anti-drop bracket including: a body, a first protrusion protruding from an inner side of the body, a first stop protruding downward from the first protrusion and facing the inner side of the body, and a first limiting groove formed between the first protrusion, the inner side of the body and the first stop, the inner side of the body being used to abut against a frame strip of the backplate, and the first limiting groove being used to receive a top edge of the frame strip.

2. The expansion device as claimed in claim 1, wherein, The first stop has a first inclined edge that gradually slopes toward the body.

3. The expansion device as claimed in claim 2, wherein, The connector includes a second protrusion that protrudes from the inner side of the body and is directly opposite the first protrusion, a second stop that protrudes upward from the second protrusion and is directly opposite the first stop, and a second limiting groove formed between the second protrusion and the second stop, the second limiting groove being used to receive a bottom edge of the frame strip.

4. The expansion device as claimed in claim 3, wherein, The second stop has a second oblique edge that gradually slopes toward the body.

5. The expansion device as claimed in claim 4, wherein, The anti-fall bracket includes a lever that protrudes upward from the body of the connector and gradually bends outward.

6. The expansion device as claimed in claim 5, wherein, The inner surface of the body of the connector has an arc-shaped recess.

7. The expansion device as claimed in claim 5, wherein, The anti-fall bracket includes an elastic metal sheet embedded in the body of the connector and the lever plate.

8. The expansion device as claimed in claim 5, wherein, The anti-fall bracket includes an extension plate extending from the second protrusion of the connector and an insert plate protruding downward from the extension plate and aligned with the hook plate. The insert plate can be inserted into the expansion slot together with the electrical connection portion of the circuit board.

9. The expansion device as claimed in claim 8, wherein, The extension plate has a notch at one end for receiving one side of the electrical connection portion of the circuit board.

10. The expansion device as claimed in claim 8, wherein, The anti-fall bracket includes a support plate that extends rearward from the body of the connector and is connected to the extension plate, and an inner side of the support plate is used to abut against the back plate.

11. The expansion device as claimed in claim 10, wherein, The support plate has an arc-shaped recess on one inner side.

12. The expansion device as claimed in claim 11, wherein, The anti-fall bracket includes an elastic metal sheet embedded in the body of the connector, the lever plate, and the support plate.

13. The expansion device as claimed in claim 10, wherein, The back panel has one or more magnetic attachment points in a predetermined area, and the anti-drop bracket has one or more magnetic attachment points.

14. The expansion device as claimed in claim 1, wherein, The anti-fall bracket includes a support plate for abutting against the back plate, and an inner side of the support plate has a groove. The connector also includes a slider that protrudes from the body and slides in the groove.

15. The expansion device as claimed in claim 14, wherein, The anti-fall bracket includes an extension plate connected to the support plate and an insert plate protruding downward from the extension plate and aligned with the hook plate. The insert plate can be inserted into the expansion slot together with the electrical connection portion of the circuit board.

16. The expansion device as claimed in claim 15, wherein, The extension plate has a notch at one end for receiving one side of the electrical connection portion of the circuit board.

17. The expansion device as claimed in claim 15, wherein, The anti-fall bracket includes a second protrusion extending from the extension plate, a second stop protruding upward from the second protrusion, and a second limiting groove formed between the second protrusion and the second stop, the second limiting groove being used to receive a bottom edge of the frame strip.

18. The expansion device as claimed in claim 14, wherein, The back panel has one or more magnetic attachment points in a predetermined area, and the anti-drop bracket has one or more magnetic attachment points.
