Abstract

A shock mount assembly is provided for mounting a circuit board in a housing of a handheld computer. The shock mount assembly comprises a frame, configured to receive the circuit board, and a clamp, configured to secure the frame to the housing. The frame comprises a plurality of tabs, each of the tabs sheathed in a shock-absorbent material and configured to be received by corresponding pockets in the housing. The clamp comprises receiving portions shaped to receive a corresponding tab of the frame. When the frame is secured to the housing by the clamp, the pocket of the housing and the receiving portion of the clamp encapsulate the corresponding tab of the frame, thereby restricting its movement. A frame and a housing are also provided.

Claims

1. A shock mount assembly for mounting a circuit board in a housing of a computer, the shock mount assembly comprising:

a frame configured to receive the circuit board, the frame comprising a plurality of tabs, each of the tabs sheathed in a shock-absorbent material and configured to be received by corresponding pockets in the housing; and

a clamp configured to secure the frame to the housing, the clamp comprising receiving portions shaped to receive a corresponding tab of the frame;

wherein when the frame is secured to the housing by the clamp, the pocket of the housing and the receiving portion of the clamp encapsulate the corresponding tab of the frame, thereby restricting its movement.

2. The shock mount assembly of claim 1, wherein the frame comprises four tabs.

3. The shock mount assembly of claim 2, wherein two of the four tabs are located on one side of the frame and two of the four tabs are located on an opposite side of the frame.

4. The shock mount assembly of claim 1, wherein the shock-absorbent material is rubber.

5. The shock mount assembly of claim 1, wherein the receiving portions of the clamp are located at opposing ends of the clamp.

6. The shock mount assembly of claim 1, wherein the pockets in the housing and the receiving portions of the clamp are c-shaped.

7. The shock mount assembly of claim 1, wherein the housing further includes a plurality of stops configured to restrict movement of the frame within the housing.

8. The shock mount assembly of claim 7, where the stops is configured in each of the six axes of potential movement.

9. The shock mount assembly of claim 7, wherein the stops comprise a hard plastic or a semi-hard plastic.

10. A frame configured to support a circuit board for mounting in a housing of a computer, the frame comprising a plurality of tabs, each of the tabs positioned away from the corners of the frame and configured to be received by corresponding pockets in the housing.

11. The frame of claim 10, wherein the frame comprises four tabs.

12. The frame of claim 11, wherein two of the four tabs are located on one side of the frame and two of the four tabs are located on an opposite side of the frame.

13. The frame of claim 10, wherein each of the tabs is configured to be attached to the housing via a screw.

14. The frame of claim 10, wherein each of the tabs is sheathed in a shock-absorbent material.

15. The frame of claim 13, wherein the shock-absorbent material is rubber.

16. A housing of a computer for receiving a circuit board mounted on a frame, the housing comprising:

a plurality of pockets configured to receive a corresponding plurality of tabs of the frame, and a receiving means configured to secure the frame to the housing.

17. The housing of claim 16, wherein the receiving means is configured to secure the frame to the housing using a screw.

18. The housing of claim 16, wherein the receiving means is configured to secure the frame to the housing using a clamp.

19. The housing of claim 18, wherein each of the tabs of the frame is sheathed in a shock-absorbent material.

20. The housing of claim 16 further comprising a plurality of stops configure to restrict motion of the frame within the housing.

21. The housing of claim 19, where the stops are configured in each of the six axes of potential movement.

22. The housing of claim 19, wherein the stops comprise a hard plastic or a semi-hard plastic.
