DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

FIG. 1, is an embodiment of a server assembly including a chassis 100 and a removable server module 200 mounted in the chassis 100.

The chassis 100 includes a bottom wall 10 and two sidewalls 20 perpendicularly extending from opposite sides of the bottom wall 10. A dividing plate 13 is uprightly set on the bottom wall 10 between the sidewalls 20 and parallel to the sidewalls 20. The dividing plate 13 and one of the sidewalls 20 cooperatively form a receiving space for receiving the server module 200. A backplane 14 is perpendicularly fixed on a rear end of the bottom wall 10. A connector 142 is set on the backplane 14 between the dividing plate 13 and the one of the sidewalls 20.

The server module 200 includes a bottom plate 201, two side plates 203 perpendicularly extending from opposite sides of the bottom wall 10, a mounting plate 20 fixed on an inner side of one of the side plates 203 near a rear end of the server module 200, and a connecting plate 30 mounted to the mounting plate 20. A plurality of function units, such as central processing units, is set on the bottom plate 201.

FIG. 2, shows the mounting plate 20 including a main plate 21 and two flanges 23 extending inward from opposite sides of the main plate 21 for reinforcing the main plate 21. Four supporting posts 24 protrude on an inner surface of the main plate 21. Each supporting post 24 defines a screw hole 242 along an axis. Two mounting rods 25 respectively protrude on the inner surface of the main plate 21, at a front end of the main plate 21 and near the flanges 23. Two upright positioning slots 26 are respectively defined in the main plate 21 near inner sides of the mounting rods 25. The main plate 21 defines a plurality of fixing holes 27, for fixing the main plate 21 on the side plate 203 with screws or bolts.

The connecting plate 30 defines four elongated through slots 31 along a front-to-rear direction. The diameter of each supporting post 24 is larger than the size of the through slots 31 along a width direction. A plurality of connecting portions, such as golden fingers (not labeled), are set on a rear end of the connecting plate 30, for electrical connection with the connector 142.

FIG. 3, shows the connecting plate 30 is resiliently attached to the mounting plate 20 via two resisting members 40, four flexible members 50, and four fasteners 60. Each resisting member 40 includes a mounting piece 41, a connecting piece 42 perpendicularly extending from one side of the mounting piece 41, a resilient and arc-shaped resisting piece 43 extending from a rear side of the connecting piece 42, and a U-shaped engaging piece 45 extending from a distal end of the resisting piece 43 opposite to the connecting piece 42. A through hole 411 is defined in a center of the mounting piece 41. An upright positioning tab 413 protrudes on a rear side of the mounting piece 41.

Each flexible member 50 is a column, and defines a ring shaped locking slot in a circumference of the column to form a neck portion 51 and two flange portions 52 formed at opposite ends of the neck portion 51. A through hole 53 is defined in the column along an axis of the column. Each flexible member 50 further defines four arc-shaped through apertures 54 around the through hole 53, to increase flexibility of the flexible member 50. The flexible members 50 are made of flexible material, such as rubber. Each fastener 60 includes a head 61 and a screw portion 63. The diameter of the head 61 is larger than the diameter of the through hole 53.

FIG. 3 and FIG. 4, show in assembling the connecting plate 30 to the mounting plate 20, the position tabs 413 are respectively inserted in the positioning slots 26. The mounting rods 25 respectively engage in the through holes 411, to fasten the mounting pieces 41 to the main body 21. The flexible members 50 are respectively pressed to be deformed to engage in the through slots 31. The screw portions 63 of fasteners 60 extend through the through holes 53 to respectively screw into the screw holes 242. The head 61 is blocked by the corresponding flexible member 50. The flange portions 52 of each flexible member 50 are blocked by two opposite side surfaces of the connecting plate 30. Therefore the connecting plate 30 is supported on the supporting posts 24. The engaging pieces 45 clamps a front end of the connecting plate 30. The resisting pieces 43 are deformed to push the connecting plate 30 rearward.

FIG. 5, shows in assembling the server module 200, is slid into the receiving space of the chassis 100, with the rear end aligning with the backplane 14, until the golden fingers of the connecting plate 30 are plugged into the connector 142.

In this embodiment, the resisting members 40 resiliently resist against the connecting plate 30 rearward, which can counteract the front-to-rear direction tolerance to prevent the connecting plate 30 from releasing from the backplane 14 in the front-to-rear direction. The neck portions 51 of the flexible members 50 engaging with edges of through slots 31 can counteract the up-to-down direction tolerance to prevent the connecting plate 30 from loosing in the up-to-down direction; the flange portions 52 of the flexible members 50 engaging with the side surfaces of the connecting plate 30 can counteract the left-to-right direction tolerance to prevent the connecting plate 30 from loosening in the left-to-right direction. In addition, ensuring that the golden fingers of the connecting plate 30 are movable to properly align with the connector 142, which can decrease damage to the connector 44 and the connecting plate 30 during the insertion of the server module 200 into the chassis 100.

It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
