1. Technical Field
The present disclosure relates to a testing apparatus for an expansion card.
2. Description of Related Art
Expansion cards includes a plurality of conditions that need to be tested, and different testing conditions need a different testing angles. When the expansion card being tested, the expansion card is sandwiched between a mounting clamp and a supporting mechanism, which is inconvenient to adjust the testing angle.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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.
Referring to
The testing desk 10 includes a base 11 and two securing portions 13 extending from an edge of the base 11. Each of the two securing portion 13 defines a securing hole 131. The base 11 is rectangular shaped. Each of the two securing portions 13 is slanted relative to the base 11, and an obtuse angle is defined between the base 11 and each of the two securing portions 13. A lifting device 50 is secured to the base 11. The lifting device 50 includes a positioning post 51, a lifting post 53 received in the positioning post 51, and two operating poles 55 attached to the lifting post 53. An inner screw thread (not shown) is defined in an inner surface of the positioning post 51. An outer screw thread 531 corresponding to the inner screw thread is defined in the lifting post 53. The outer screw thread 531 is engaged with the inner screw thread, to move the lifting post 53 up and down relative to the positioning post 51 in a direction substantially perpendicular to the base 11. A driving portion 57 is attached to the lifting post 53 and located between the two operating poles 55. In one embodiment, the driving portion 57 is a ball bearing.
The supporting tray 20 includes a supporting panel 21 and two retaining portions 23 extending from an edge of the supporting panel 21. The supporting panel 21 can be rectangular in shape. Each of the two retaining portions 23 is slanted relative to the supporting panel 21, and an obtuse angle is defined between the supporting panel 21 and each of the retaining portions 23. A plurality of positioning blocks 211 are attached to the supporting panel 21. In one embodiment, a size of each of the plurality of positioning blocks 211, or an arrangement of the plurality of positioning block 211 can be adjusted according to a size or an arrangement of the expansion card 40, so that the expansion card 40 can be stably secured to the supporting panel 21 by the plurality of positioning block 211. A fixing hole 214 is defined in the supporting panel 21 away from the retaining portions 23. A retaining hole 231, corresponding to the securing hole 131, is defined in each of the two retaining portions 23.
The clamp 30 defines a mounting hole 31, corresponding to the fixing hole 214. A gasket 33 is attached to the clamp 30 for preventing the clamp 30 from abutting the expansion card 40. In one embodiment, the gasket 33 is a plastic and is directed towards expansion card 40.
Referring to
The clamp 30 is above the supporting tray 20, and the mounting hole 31 is aligned with the fixing hole 214. A fixing member 70 is engaged in the mounting hole 31 and the fixing hole 214, to moveably secure the clamp 30 to the supporting panel 21.
When the expansion card 40 needs to be tested, the fixing member 70 is adjusted. The clamp 30 is moved away from the supporting panel 21, and the expansion card 40 is located between the clamp 30 and the supporting panel 21. The clamp 30 is moved towards the supporting panel 21, and the clamp 30 is pressed on the expansion card 40. Therefore, the expansion card 40 is steady nipped between the supporting panel 21 and the clamp 30, to be tested.
Referring to
When the expansion card 40 need to be moved downward, the two operating poles 55 are operated in the clockwise direction, and the lifting post 53 is moved downward relative to the base 11 in the first direction. The driving portion 57 is rotated to move the supporting panel 21 downward, and each of the two retaining portions 23 is rotated about the stud 61 relative to each of the two securing portions 13, until the expansion card 40 is moved to a predetermined angle.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
