Description

Hard disk drive testing clamp

[technical field]

The invention relates to field of hard disks, especially about a kind of test fixture of hard disk drive.

[background technology]

Existing hard disk drive the time generally is disposable a plurality of hard disk drives to be put into a testing jig simultaneously in test, connects testing apparatus then hard disk drive is tested.But there is following shortcoming in this kind test: 1) hard disk drive can not effectively be located, thereby makes test result inaccurate, even may damage hard disk drive; 2) do not have shock absorbing device, thereby when these testing jig vibrations, can cause damage hard disk drive.

[summary of the invention]

The object of the present invention is to provide a kind of test fixture that in test process, can effectively protect hard disk drive.

The object of the present invention is achieved like this: this hard disk drive testing clamp comprises pedestal, guide rail, X-axis clamping elements and be used to connect the connector of testing apparatus and hard disk drive to be measured, pedestal has upper surface and the lower surface that is oppositely arranged, guide rail, clamping element and connector all are installed in the upper surface of this pedestal, guide rail is provided with and is used for guide pass that hard disk drive to be measured is led, clamping element is positioned on the movement locus of hard disk drive to be measured, connector is positioned at the terminal point of this hard disk drive movement travel, and this connector is provided with the conducting terminal that connects with hard disk drive to be measured, every cover X-axis clamping element comprises one second clamping element of one first clamping element of rubber-like and rigidity, and this first, distance between second clamping element is less than the width of hard disk drive on directions X.

Described guide rail has two, and these two guide rails be arranged in parallel, and first, second clamping element lays respectively at the outside of two guide rails.

Described guide rail is " L " type, and it comprises first guide rail and horizontally disposed second guide rail of vertical setting, and this first guide rail has the first vertical guide pass, and second guide rail has the horizontal second guide rail face.

The top of described guide rail is equipped with and is used at the Z of the spacing hard disk drive to be measured of Z-direction axle locating part.

The lower surface of described pedestal is fixed with the shock-absorbing cushion block.

Also be installed with the Y-axis locating part on the described connector, this Y-axis locating part is positioned at the terminal point of hard disk drive movement travel.

Compared with prior art, the present invention has following advantage: the guide effect when guide rail can play hard disk drive inserted, clamping element can clamp hard disk drive, thereby prevents it from rocking in test process and cause damage.

[embodiment]

See also Fig. 1 to Fig. 4, hard disk drive testing clamp of the present invention comprises pedestal 1 and is fixedly mounted on guide rail 2,6, X-axis clamping elements 3 and connector 4 on this pedestal, this pedestal 1 is used to carry whole anchor clamps and hard disk drive to be measured 5, this guide rail 2,6 is used for playing the guiding role when hard disk drive 5 inserts, this X-axis clamping element 3 is used at X-direction clamping hard disk drive 5, and this connector 4 is used to connect testing apparatus and hard disk drive to be measured 5.

Pedestal 1 is tabular, it is placed on the testing jig, the lower surface 12 that this pedestal 1 has upper surface 11 and is oppositely arranged with it, and this upper surface 11 is parallel to surface level, and guide rail 2,6, clamping element 3 and connector 4 all are fixedly arranged on this upper surface 11, and this lower surface 12 is used to be supported on testing jig.Guide rail has two, these two guide rails 2,6 be parallel to each other and its bearing of trend consistent with the direction of insertion of hard disk drive 5.Guide rail 2,6 is " L " type, it comprises

first guide rail

21,61 of vertical setting and affixed with it and be horizontally disposed

second guide rail

22,62, this

first guide rail

21,61 has the first vertical guide pass 211,611, this

second guide rail

22,62 has horizontal second guide rail face 221,621, when hard disk drive 5 inserts this test fixture, hard disk drive 5 attaches first, second guide pass motion of this two couple, thereby the motion of hard disk drive 5 is played the effect of guiding by this first, second guide pass.

X-axis clamping element 3 has two covers, each overlaps second clamping element 32 that X-axis clamping element 3 includes a rubber-like first clamping element 31 and a rigidity, first clamping element 31 is positioned at the wherein outside of a guide rail 2, second clamping element 32 is positioned at the outside of another one guide rail 6, and this first,

second clamping element

31,32 all has at least part to stretch between two guide rails 2,6.When not inserting hard disk drive 5, distance between first,

second clamping element

31,32 in every cover is slightly less than the width of hard disk drive 5 on X-direction, thereby after hard disk drive 5 inserted, the elastic force by this first clamping element 31 made this first,

second clamping element

31,32 tight these hard disk drives 5 of clamping.In addition, tilt when preventing that hard disk drive 5 from inserting these test fixtures, the upper surface 11 of this pedestal 1 also is installed with Z axle locating part 33, this Z axle locating part 33 is positioned at the outside of guide rail 6, its along continuous straight runs stretches between two guide rails 2,6, and on Z-direction, distance between this Z axle locating part 33 and second guide pass 621 should be slightly larger than the thickness of hard disk drive 5, thereby under guaranteeing the situation that hard disk drive 5 can not tilt when inserting, this Z axle locating part 33 can not scratch hard disk drive 5 surfaces yet.

Connector 4 comprises body 41 and is located at conducting terminal 42 on this body 41, this body 41 is installed with Y-axis locating part 43 towards a side of guide rail 2,6, this Y-axis locating part 43 is positioned at the final position of hard disk drive 5 movement travels, movement travel when it is used for hard disk drive 5 insertions is carried out spacing, conducting terminal 42 is positioned at these Y-axis locating part 43 top certain altitudes and extends to guide rail 2,6 along negative Y-axis, and it is used for hard disk drive 5 insertion backs and pegs graft with its serial ports.

In the present embodiment, the following basal surface 12 of pedestal 1 also sticks by glue four shock-absorbing cushion blocks 7, and each cushion block 7 is evenly distributed on the lower surface 12 of pedestal, thereby after testing jig is impacted, by these shock-absorbing cushion block 7 shock-absorbings, thereby avoid hard disk drive 5 to be measured is caused damage.

The principle of work of this hard disk drive testing clamp is as follows: this test fixture is put on the testing jig, testing apparatus is connected with connector, then hard disk drive 5 is inserted this test fixture along first, second guide pass level of guide rail 2,6, when hard disk drive 5 moves to Y-axis locating part 43 position contacting, the motion of hard disk drive 5 stops, the conducting terminal 42 of connector 4 well connects with the serial ports and the power connection of hard disk drive 5 to be measured at this moment, promptly can test hard disk drive 5 by testing apparatus.
