Abstract

A server casing includes a frame and a plate connecting structure disposed in the frame and including a plate and a board. A first rivet hole of the plate has a first outer hole edge and a first inner hole edge greater than the first outer hole edge. A first guide surface connects the first outer hole edge and the first inner hole edge. The board has a board edge corresponding to the first rivet hole. A first arm is formed on the board edge. After the first arm is pressed to abut against the first guide surface, the pressed first arm deforms along the first guide surface to be located in the first rivet hole, so as to fix the board to the plate.

First claim

What is claimed is:

1. A server casing comprising:
a frame; and
a plate connecting structure disposed in the frame, the plate connecting structure comprising:
a plate having a first rivet hole and a second rivet hole, the first rivet hole being symmetrical to the second rivet hole, the first rivet hole having a first outer hole edge located on an outer surface of the plate and a first inner hole edge located on an inner surface of the plate, the first outer hole edge being longer than the first inner hole edge, a first guide surface connecting the first outer hole edge and the first inner hole edge, the second rivet hole having a second outer hole edge located on the outer surface of the plate and a second inner hole edge located on the inner surface of the plate, the second outer hole edge being longer than the second inner hole edge, a second guide surface connecting the second outer hole edge and the second inner hole edge; and
a board having at least one board edge corresponding to the first rivet hole, a first arm and a second arm, the first arm and the second arm bending in opposite directions and being spaced apart from each other, the first arm being symmetrical to the second arm, the first arm having a first arm portion and a second arm portion, the first arm portion being connected between the at least one board edge and the second arm portion to make the second arm portion protrude from the at least one board edge, the second arm having a third arm portion and a fourth arm portion, the third arm portion extending from the at least one board edge, the fourth arm portion extending from the third arm portion, the second arm portion and the fourth arm portion being configured to deform along the first guide surface and the second guide surface respectively to make the first arm and the second arm be located in the first rivet hole and the second rivet hole respectively and be engaged with the first guide surface and the second guide surface by surface-to-surface contact respectively so as to fix the board to the plate after an end of the second arm portion away from the first arm portion and an end of the fourth arm portion away from the third arm portion ares configured to be pressed to abut against the first guide surface and the second guide surface respectively.

2. The server casing of claim 1 , wherein after the second arm portion is configured to be pressed to abut against the first guide surface, the second arm portion is configured to deform with the first arm portion along the first guide surface to be located in the first rivet hole so as to make a first pressed surface of the second arm portion coplanar with the outer surface of the plate.

3. The server casing of claim 2 , wherein a length of the first arm portion is less than a length of the second arm portion.

4. The server casing of claim 1 , wherein a flash groove is formed on the at least one board edge corresponding to at least one side of the first arm to contain a deformed portion of the first arm when the first arm is configured to deform along the first guide surface to be located in the at least first rivet hole.

5. The server casing of claim 1 , wherein after the fourth arm portion is configured to be pressed to abut against the second guide surface, the fourth arm portion is configured to deform with the third arm portion along the second guide surface to be located in the second rivet hole, so as to make a second pressed surface of the fourth arm portion coplanar with the outer surface of the plate.

6. The server casing of claim 1 , wherein an area of the first outer hole edge is greater than an area of the first inner hole edge, and an area of the second outer hole edge is greater than an area of the second inner hole edge.

7. The server casing of claim 1 , wherein the at least one board edge has a support platform for supporting a bridge structure located between the first rivet hole and the second rivet hole.

8. A plate connecting structure for partitioning at least one containing space in a server casing, the plate connecting structure comprising:
a plate having a first rivet hole and a second rivet hole, the first rivet hole being symmetrical to the second rivet hole, the first rivet hole having a first outer hole edge located on an outer surface of the plate and a first inner hole edge located on an inner surface of the plate, the first outer hole edge being longer than the first inner hole edge, a first guide surface connecting the first outer hole edge and the first inner hole edge, the second rivet hole having a second outer hole edge located on the outer surface of the plate and a second inner hole edge located on the inner surface of the plate, the second outer hole edge being longer than the second inner hole edge, a second guide surface connecting the second outer hole edge and the second inner hole edge; and
a board having at least one board edge corresponding to the first rivet hole, a first arm and a second arm, the first arm and the second arm bending in opposite directions and being spaced apart from each other, the first arm being symmetrical to the second arm, the first arm having a first arm portion and a second arm portion, the first arm portion being connected between the at least one board edge and the second arm portion to make the second arm portion protrude from the at least one board edge, the second arm having a third arm portion and a fourth arm portion, the third arm portion extending from the at least one board edge, the fourth arm portion extending from the third arm portion, the second arm portion and the fourth arm portion being configured to deform along the first guide surface and the second guide surface respectively to make the first arm and the second arm be located in the first rivet hole and the second rivet hole respectively and be engaged with the first guide surface and the second guide surface by surface-to-surface contact respectively so as to fix the board to the plate after an end of the second arm portion away from the first arm portion and an end of the fourth arm portion away from the third arm portion are configured to be pressed to abut against the first guide surface and the second guide surface respectively.

9. The plate connecting structure of claim 8 , wherein after the second arm portion is configured to be pressed to abut against the first guide surface, the second arm portion being configured to deform with the first arm portion along the first guide surface to be located in the first rivet hole, so as to make a first pressed surface of the second arm portion coplanar with the outer surface of the plate.

10. The plate connecting structure of claim 9 , wherein a length of the first arm portion is less than a length of the second arm portion.

11. The plate connecting structure of claim 8 , wherein a flash groove is formed on the at least one board edge corresponding to at least one side of the first arm to contain a deformed portion of the first arm when the first arm is configured to deform along the first guide surface to be located in the first rivet hole.

12. The plate connecting structure of claim 8 , wherein after the fourth arm portion is configured to be pressed to abut against the second guide surface, the fourth arm portion is configured to deform with the third arm portion along the second guide surface to be located in the second rivet hole, so as to make a second pressed surface of the fourth arm portion coplanar with the outer surface of the plate.

13. The plate connecting structure of claim 8 , wherein an area of the first outer hole edge is greater than an area of the first inner hole edge, and an area of the second ou
