Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a fixture for testing a mid-plane of a blade server, and particularly to a fixture with a simplified configuration and convenient usability.

2. Background

A blade server is newly developed based on the high speed of the network. The blade server comprises a carrier enclosure, a fixture unit, and a mid-plane. The carrier enclosure comprises a number of motherboards in shape of blade. The fixture unit includes a number of power suppliers, a number of administration modules, and a rear bracket. The mid-plane is a printed circuit board, which connects the carrier enclosure and the fixture unit. The function of the mid-plane reflects the ability of data inter-communication. Therefore, a mid-plane test is of great importance. The conventional process of mid-plane test is to draw out the power suppliers, the administration modules, and the rear bracket from the cabinet of the blade server at first. Then mount the mid-plane to be tested to the rear bracket, and install all the other modules to the cabinet to form an information handling system to test the function of the mid-plane. When test another mid-plane, the process cited above is executed again, and the new mid-plane is mounted on the blade server for testing. The conventional mid-plane testing process is complicated and time-consuming.

Thus, an improved fixture for testing a mid-plane of a blade server which overcomes the above-mentioned problems is desired.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring to FIGS. I and 2, a fixture for testing a mid-plane of a blade server in accordance with a preferred embodiment of the present invention is shown. The fixture includes a carrier enclosure 100, a fixture unit 200, a base board 300, and a U-shaped handspike 400.

The carrier enclosure 100 is used for enclosing motherboards and cooling fans. The carrier enclosure 100 comprises a bottom plate 110, and two side plates 120 extending from opposite sides of the bottom plate 110. A sliding block 121 is formed outwardly from each side plate 120. A pair of sliding rails 111 is stamped outwardly on the bottom plate 110. Each sliding rail 111 has a U shape section.

The fixture module 200 is used for installing administration apparatus, connection apparatus, and a mid-plane. The fixture module 200 comprises a receiving location 210 for mounting a mid-plane thereon and two side walls 220. Two fasten members 211 are formed on the fixture module 200 at opposite sides of the receiving location 210 respectively. Two shafts 221 are respectively formed on the two sidewalls 220 for a locking unit 500 rotating thereof. A power protection switch 230 is attached on one of the two sidewalls 220 with a sensor 231 mounted thereon. The fixture for testing a mid-plane of a blade server is powered on when the sensor 231 is pressed down.

The base board 300 has two tabs 310 formed at opposite sides thereon. Each tab 311 comprises a post 311 stamped outwardly therefrom. A pair of guiding rails 320 is formed on the base board 300, corresponding to the sliding rails 111 of the carrier enclosure 100.

The handspike 400 comprises a crossbeam 410 and a pair of side arms 420 extending vertically from the crossbeam 410 respectively. Two handles 411 are formed on the crossbeam 410. A concave 421 is defined in a top edge of each of the two side arms 420. Each side arm 420 has a guiding slot 422 defined in a middle portion, and a through hole 423 defined in a bottom portion.

Referring also to FIG. 3, the carrier enclosure 100 is slidably mounted on the base board 300 by sliding the leader rails 111 along the guiding rails 320. The handspike 400 is attached to the carrier enclosure 100 with the slide blocks 121 received in the guiding slots 422, posts 311 of the tabs 310 are inserted into the through holes 423 of the handspike 400 respectively, such that the handspike 400 and the carrier enclosure 100 are combined together and rotatably attached to the base board 300.

The fixture unit 200 is fixed on the base board 300. A U-shaped locking member 500 is attached to the fixture unit 200 and rotated around the shafts 221 of the fixture unit 200. The locking unit 500 comprises a lever 510 thereon.

Referring also to FIG. 4, in use, a mid-plane 10 to be tested is attached to the receiving location 210 of the fixture unit 200 and is fastened by the fasten member 211. The handles 411 of the handspike 400 is pushed toward the mid-plane 10, the handspike 400 is thereby rotated around the posts 311, the sliding blocks 121 move upwardly in the guiding slots 422 to drive the carrier enclosure 100 slide along the guiding rails 320 toward the fixture unit 200, so that the carrier enclosure 100 and the fixture unit 200 connect together through the mid-plane 10. The locking unit 500 is then rotated toward the handspike 400, the level 510 is engaged in the concave 421 of the handspike 400, the locking unit 500 presses the sensor 231 on the power protection switch 230 to turn on the fixture, then the mid-plane 10 is tested. After the testing is completed, the locking unit 500 is rotated in a reverse direction to disengage the locking unit 500 from the handspike 400, the handspike 400 is slide away from the fixture unit 200, then draw out the mid-plane 10 so that the mid-plane 10 is removed from the fixture unit 200.

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