Abstract

A server structure includes a transfer board, a connecting backplane, a first bridge circuit board and a second bridge circuit board. The transfer board has oppositely at least one first connector and at least one second connector. The connecting backplane has at least one third connector located correspondingly to the at least one first connector and at least one fourth connector located in correspondingly to the at least one second connector. To electrically couple the transfer board and the connecting backplane, the first bridge circuit board is inserted between the first connector and the third connector, while the second bridge circuit board is inserted between the second connector and the fourth connector. The communication bandwidth between the transfer board and the connecting backplane can be extended by the combination of the first bridge circuit board and the second bridge circuit board.

First claim

What is claimed is:

1. A server with dual-side bridge circuit boards, comprising:
a transfer board, having a first top surface and a first bottom surface opposing to the first top surface, one end of the first top surface having at least one first connector, another end of the first bottom surface having at least one second connector;
a connecting backplane, having a second top surface and a second bottom surface opposing to the second top surface, the second top surface having at least one third connector located correspondingly to the at least one first connector, the second bottom surface having at least one fourth connector located in correspondingly to the at least one second connector;
a first bridge circuit board, inserted between the at least one first connector and the at least one third connector, electrically coupled with the transfer board and the connecting backplane; and
a second bridge circuit board, inserted between the at least one second connector and the at least one fourth connector, electrically coupled with the transfer board and the connecting backplane;
wherein a bandwidth for a communication between the transfer board and the connecting backplane is extended by a combination of the first bridge circuit board and the second bridge circuit board.

2. The server with dual-side bridge circuit boards of claim 1 , wherein the transfer board further includes a supportive frame fixed at the first bridge circuit board, the first bridge circuit board and the supportive frame being integrated as a unique a piece prior to being inserted to couple the at least one first connector.

3. The server with dual-side bridge circuit boards of claim 2 , wherein the supportive frame further includes two opposing lateral slippery grooves for sliding and guiding the first bridge circuit board in between thereof so as to be fixed inside the supportive frame.

4. The server with dual-side bridge circuit boards of claim 2 , wherein the supportive frame further includes at least one first fixation pillar fixed at the first bridge circuit board.

5. The server with dual-side bridge circuit boards of claim 2 , wherein the supportive frame further includes at least one hook protrusion for constraining the first bridge circuit board.

6. The server with dual-side bridge circuit boards of claim 2 , wherein the supportive frame further includes at least one observation hole for serving an observation purpose of checking an engagement state of the first bridge circuit board and the at least one first connector of the transfer board under the supportive frame.

7. The server with dual-side bridge circuit boards of claim 2 , wherein the supportive frame further includes at least one second fixation pillar fixed at the first bottom surface.

8. A method for assembling a server with dual-side bridge circuit boards, comprising the steps of:
(a) sending a first bridge circuit board into a supportive frame by sliding along two lateral slippery grooves of the supportive frame, and having at least one first fixation pillar of the supportive frame to fix the first bridge circuit board in the supportive frame;
(b) inserting a combination of the first bridge circuit board and the supportive frame to engage at least one first connector on a first top surface of a transfer board;
(c) having the supportive frame to be fixed by at least one second fixation pillar applied from a first bottom surface of the transfer board so as to fix the supportive frame and the first bridge circuit board on the transfer board;
(d) inserting a second bridge circuit board to engage at least one second connector on the first bottom surface;
(e) fixing the second bridge circuit board and the transfer board on a base casing; and
(f) engaging at least one third connector and at least one fourth connector of a connecting backplane respectively with the first bridge circuit board and the second bridge circuit board so as to allow the first bridge circuit board to be coupled between the at least one third connector and the at least one first connector and the second bridge circuit board to be coupled between the at least one fourth connector and the at least one second connector.

9. The method for assembling a server with dual-side bridge circuit boards of claim 8 , wherein, in the step (a), while the first bridge circuit board slides into the supportive frame along the two lateral slippery grooves, the first bridge circuit board is to contact and thus be constrained by at least one hook protrusion of the supportive frame.
