Abstract

A connection assembly (100) includes a base structure (110); a backplane (120) coupled to the base structure (110), the backplane (120) including a first circuit board (122); and a tray module (140) configured to couple to the backplane (120). The tray module (140) includes a tray body (160) including a second circuit board (162); and a bridge member (150) to which the tray body (160) is moveably coupled. The tray body (160) moves relative to the backplane (120) while the bridge member (150) remains stationary relative to the backplane (120). Managed connectivity components (250) on the second circuit board (162) remain connected to the first circuit board (122) even while the tray body (160) is pivoting relative to the backplane (120).

Claims

a. a base structure;

b. a backplane coupled to the base structure, the backplane including a first circuit board;

c. a tray module configured to couple to the backplane, the tray module including;

i. a tray body including a second circuit board and at least one managed connectivity component; and

ii. a bridge member to which the tray body is moveably coupled so that the tray body is moveable relative to the backplane when the tray module is coupled to the backplane, the bridge member being coupled to the backplane in a fixed orientation when the tray module is coupled to the backplane so that the bridge member does not pivot relative to the backplane, and the bridge member providing a secure electrical connection between the second circuit board and the first circuit board to connect the managed connectivity component to a data management network even while the tray body is moved relative to the backplane.

2. The connection assembly of claim 1, wherein the tray body is configured to pivot relative to the bridge member.

3. The connection assembly of claim 1, further comprising a connector electrically connected to the second circuit board, the connector being configured to mate with the first circuit board to electrically connect the second circuit board to the first circuit board.

4. The connection assembly of claim 1, wherein the base structure includes a drawer.

5. The connection assembly of claim 1, wherein the base structure includes a chassis.

6. The connection assembly of claim 1, further comprising a plurality of optical adapters mounted to the tray body, each adapter defining at least one port at which the managed connectivity component is disposed.

7. The connection assembly of claim 1, wherein the tray body includes a cable storage region.

8. The connection assembly of claim 1, wherein the backplane includes a plurality of contact pads;

and wherein the connection assembly further comprises a plurality of tray modules, each tray module including a connector that is configured to touch at least one of the contact pads.

9. The connection assembly of claim 1, further comprising a plurality of tray modules configured to couple to the backplane, wherein each tray module is separately removable from the backplane.

10. The connection assembly of claim 1, wherein the backplane is angled relative to the base structure.

11. The connection assembly of claim 1, further comprising an adapter holder arrangement disposed on the tray body for retaining at least one optical adapter, the adapter holder arrangement including latching arms arranged in rows and columns, wherein the latching arms in each column face in a common direction for that column.

12. The connection assembly of claim 2, wherein the tray body is configured to pivot at least about 45°

relative to the backplane.

13. The connection assembly of claim 2, wherein the tray body is configured to pivot at least about 60°

relative to the backplane.

14. The connection assembly of claim 3, further comprising a flexible circuit arrangement having a first end and a second end, the first end of the flexible circuit arrangement being coupled to the second circuit board, and the second end of the flexible circuit arrangement being terminated by the connector.

15. The connection assembly of claim 11, wherein each optical adapter is held by a latching arm disposed in a first row and facing in a first direction and by a latching arm disposed in a second row and facing in an opposite second direction.

16. The connection assembly of claim 14, wherein the connector does not move relative to the bridge member.

17. The connection assembly of claim 14, wherein the bridge member includes a latch pin arrangement that fit with a mounting arrangement disposed on the backplane when the tray module is coupled to the backplane;
