Description

Technical Field

[0001] The utility model relates to the technical field of solid state hard disk testing, in particular to a testing fixture for solid state hard disks. Background Art

[0002] A solid state drive (SSD), also known as a solid-state drive, is a hard disk made of an array of solid-state electronic storage chips. SSDs are popular in the market due to their fast reading speed, light weight, and low power consumption, and the demand is increasing. However, there are certain limitations in the efficiency of producing SSDs. For example, in the way of testing SSDs, it is usually manually aligned with the test socket, and the SSD is inserted into the test socket after confirmation, and then the SSD is unplugged after the test is completed. When the SSD is functionally tested, environmental testing is usually superimposed, that is, the test fixture is placed in a high and low temperature box. At this time, the high and low temperature box will blow air, and the stability of the fixed hard disk and the fixture plug-in is particularly important. At the same time, because SSDs have different lengths due to different models, existing test fixtures are usually not compatible with the testing of fixed hard disks of different lengths. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a test fixture for solid-state hard disks, which can provide stable clamping for solid-state hard disks of different lengths.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a test fixture for a solid state hard disk, including a circuit board, on which at least one test socket is provided, the test fixture also includes a clamping device corresponding to the test socket, and each of the test fixtures includes:

[0005] A fixing rod, the fixing rod is located below the test socket and fixed on the circuit board;

[0006] A sliding rod, which is inserted into the fixed rod and can slide axially along the fixed rod;

[0007] A locking assembly, which is used to lock the fixed rod and the sliding rod to achieve the fixation of the fixed plate and the sliding rod;

[0008] A clamping assembly, wherein the clamping device is located at the end of the sliding rod, and the clamping device includes a clamping plate, which can rotate along the axis of the sliding rod and clamp the solid state hard disk at the test socket. The clamping plate is connected to the sliding rod through a fixing portion, and can be fixed to the sliding rod through the fixing portion after the clamping plate is rotated into place.

[0009] The beneficial effect of the utility model is that the fixed rod and the sliding rod form a telescopic structure with adjustable length, and the two are quickly fixed by a locking assembly to achieve relative fixation of the sliding rod and the fixed rod. Then, a rotatable pressing plate is used to press the solid state hard disk toward the circuit board. The solid state hard disks of different lengths can be fixed, and the utility model has high versatility.

[0010] Specifically, the fixing portion includes:

[0011] A rotating shaft, the rotating shaft is coaxial with the sliding rod and inserted into the end of the sliding rod, the rotating shaft can rotate along its own axis, and the end of the rotating shaft passes through the part of the sliding rod and is fixedly connected to the pressing plate;

[0012] A limiting rod, wherein the limiting rod is located inside the sliding rod, and the end of the rotating shaft away from the pressing plate can abut against the limiting rod;

[0013] A first spring is sleeved on a rotating shaft located in the sliding rod, and the first spring is always in a compressed state to press the rotating shaft tightly against the limiting rod.

[0014] The fixing part uses a first spring to limit the rotation of the rotating shaft (pressing plate), and has a compact structure and low cost.

[0015] Furthermore, a limiting portion is arranged inside the rotating shaft of the sliding rod, one end of the first spring abuts against the end of the sliding rod, and the other end of the first spring abuts against the limiting portion.

[0016] The limiting portion prevents the rotating shaft from completely separating from the sliding rod and provides a supporting surface for the first spring.

[0017] Furthermore, the pressing plate includes a plate body and a flexible member, the plate body is connected to the fixing portion, and the flexible member is attached to the side of the plate body facing the circuit board.

[0018] Because when the external force is removed, the first spring will drive the clamping plate to move and reset quickly. In order to protect the fixed hard disk, a flexible part is provided to prevent the clamping plate from having rigid contact with the solid state hard disk during movement, thereby effectively protecting the solid state hard disk.

[0019] Furthermore, the sliding rod has a plurality of positioning holes spaced apart along its axial direction;

[0020] The locking assembly is arranged on the fixed rod, and the locking assembly includes an insertion rod which can reciprocate axially vertically on the sliding rod.

[0025] When there is no external force acting on the pressing sleeve, the second spring generates elastic force due to compression, pushing the insertion rod into the positioning hole. However, when the insertion rod needs to be removed from the positioning hole, the pressing sleeve only needs to be pressed to drive the insertion rod to be removed from the positioning hole through the connecting piece.

[0026] Furthermore, both ends of the connecting member passing through the fixing rod are provided with a first inclined surface, and the pressing sleeve is provided with a second inclined surface matching and abutting against the first inclined surface;

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0042] See attached Figure 1 As shown, the test fixture for the solid-state hard disk 200 of the utility model includes a circuit board 100, on which at least one test socket is arranged, and the test fixture also includes a clamping device corresponding to the test socket, and the clamping device is used to clamp the solid-state hard disk 200 at the test interface to prevent the solid-state hard disk 200 from loosening.

[0043] See attached Figure 1 As shown, each of the test fixtures includes a fixed rod 1, a sliding rod 2, a locking assembly 3 and a clamping assembly 4. The fixed rod 1 is located below the test socket, and the fixed rod 1 is fixed on the circuit board 100. The sliding rod 2 is inserted into the fixed rod 1 and can slide axially along the fixed rod 1. The locking assembly 3 is used to lock the fixed rod 1 and the sliding rod 2 to achieve the fixation of the fixed plate and the sliding rod 2. The clamping assembly 4 is located at the end of the sliding rod 2, and the clamping device includes a clamping plate 41, and the clamping plate 41 can rotate along the axis of the sliding rod 2 and press the solid state hard disk 200 at the test socket. The clamping plate 41 is connected to the sliding rod 2 through a fixing portion, and the clamping plate 41 can be fixed to the sliding rod 2 through the fixing portion after being rotated into place.

[0044] In this embodiment, the fixed rod 1 and the sliding rod 2 form a telescopic structure with adjustable length, and the two are quickly fixed by a locking assembly 3 to achieve relative fixation of the sliding rod 2 and the fixed rod 1. Then, a rotatable pressing plate 41 is used to press the solid state drive 200 toward the circuit board 100. The solid state drives 200 of different lengths can be fixed, and the versatility is high.

[0045] In this embodiment, the rotation angle of the clamping plate 41 is 90°. Initially, the clamping plate 41 extends horizontally and is located at the insertion position, which does not hinder the insertion of the solid state drive 200. When the fixed hard drive is inserted into the test socket, the clamping plate 41 rotates upward by 90° to the clamping position, at which time the clamping plate 41 extends upward and abuts against the fixed hard drive.

[0046] The position of the sliding rod 2 can be flexibly adjusted according to the size of the fixed hard disk, that is, the length of the telescopic structure can be changed. In one embodiment, a clearance hole for the sliding rod 2 to pass through is opened on the circuit board 100. Because the sliding rod 2 is long, the fixed rod 1 is set to a hollow structure with openings at both ends, and the sliding rod 2 can pass through the fixed rod 1 from the openings at both ends.

[0047] In one embodiment, see the attached Figure 2 As shown, the fixing part includes a rotating shaft 42, a limiting rod 43 and a first spring 44. The rotating shaft 42 is coaxial with the sliding rod 2 and inserted into the end of the sliding rod 2. The rotating shaft can rotate along its own axis. The end of the rotating shaft 42 passes through the part of the sliding rod 2 and is fixedly connected to the clamping plate 41. The limiting rod 43 is located in the sliding rod 2, and the end of the rotating shaft 42 away from the clamping plate 41 can abut against the limiting rod 43. The first spring 44 is sleeved on the rotating shaft 42 located in the sliding rod 2, and the first spring 44 is always in a compressed state to press the rotating shaft 42 against the limiting rod 43.

[0048] Because it is necessary to ensure that the clamping plate 41 can rotate, but can be positioned after it rotates to a specified position and no longer rotates. Therefore, in this embodiment, the fixing portion uses a first spring 44 to limit the rotation of the rotating shaft 42 (clamping plate 41). When there is no external force, the first spring 44 is still in a compressed state, and the first spring 44 presses the rotating shaft 42 on the limiting rod 43 due to the elastic force. At this time, the rotating shaft 42 will not rotate. However, when the clamping plate 41 needs to rotate, an external force is applied to the clamping plate 41, pulling the clamping plate 41 to move toward the side away from the sliding rod 2 and rotating the clamping plate 41. At this time, the first spring 44 is continuously compressed. When the clamping plate 41 rotates to the specified position, the external force is removed, and the first spring 44 pushes the rotating shaft 42 to quickly reset to be pressed on the limiting rod 43. At this time, the clamping plate 41 and the rotating shaft 42 will not rotate by themselves.

[0049] See attached Figure 2As shown, the rotating shaft 42 is provided with a limiting portion 421 inside the sliding rod 2, and one end of the first spring 44 abuts against the end of the sliding rod 2, and the other end abuts against the limiting portion 421. The limiting portion 421 prevents the rotating shaft 42 from completely separating from the sliding rod 2 and provides an abutting surface for the first spring 44.

[0050] In one embodiment, the clamping plate 41 includes a plate body and a flexible member, the plate body is connected to the fixed portion, and the flexible member is attached to the side of the plate body facing the circuit board 100. The flexible member directly contacts the solid state drive 200, because when the external force is removed, the first spring 44 will drive the clamping plate 41 to move and reset quickly. In order to protect the fixed hard disk, the flexible member is provided to prevent the clamping plate 41 from having a rigid contact with the solid state drive 200 during the movement, thereby effectively protecting the solid state drive 200.

[0051] In one embodiment, see the attached Figure 3 As shown, the sliding rod 2 has a plurality of positioning holes 21 spaced apart along its axial direction. The locking assembly 3 is disposed on the fixed rod 1, and the locking assembly 3 includes an insertion rod 34 that can reciprocate vertically along the axial direction of the sliding rod 2, and the insertion rod 34 can be inserted into the positioning hole 21 to lock the sliding rod 2 and the fixed rod 1, or slide out of the positioning hole 21 to unlock the fixed rod 1 and the sliding rod 2.

[0052] In one embodiment, the insertion rod 34 can be manually inserted into the positioning hole 21 or slid out of the positioning hole 21. When the sliding rod 2 is moved into position, the insertion rod 34 is manually inserted through the fixed rod 1 and into the corresponding positioning hole 21. When the sliding rod 2 needs to be moved, the insertion rod 34 is manually pulled out of the positioning hole 21.

[0053] In one embodiment, in order to reduce manual operation, the locking assembly 3 further includes a pressing sleeve 31, a second spring 32 and a connecting piece 33. The pressing sleeve 31 can reciprocate along the moving direction of the insertion rod 34, and part of the insertion rod 34 is located in the pressing sleeve 31. The second spring 32 is located in the pressing sleeve 31 and abuts against the insertion rod 34. The second spring 32 provides a force for the insertion rod 34 to move toward the sliding rod 2 to insert into the positioning hole 21. The connecting piece 33 is inserted into the insertion rod 34. When the pressing sleeve 31 moves toward the fixed rod 1, the insertion rod 34 is pulled by the connecting piece 33 to move toward the side away from the sliding rod 2 to disengage from the positioning hole 21.

[0054] In this embodiment, when no external force acts on the pressing sleeve 31, the second spring 32 generates elastic force due to compression, pushing the insertion rod 34 into the positioning hole 21. However, when the insertion rod 34 needs to be separated from the positioning hole 21, the pressing sleeve only needs to be pressed, and the insertion rod 34 can be driven to separate from the positioning hole 21 through the connecting member 33.

[0055] See attached Figure 3 and attached Figure 4 As shown, both ends of the connecting member 33 passing through the fixing rod 1 are provided with a first inclined surface 331, and the pressing sleeve 31 is provided with a second inclined surface matching and abutting against the first inclined surface 331. The insertion rod 34 has a through hole for the connecting member 33 to pass through, and the portion of the connecting member 33 located inside the insertion rod 34 is provided with a third inclined surface 332, the third inclined surface 332 is perpendicular to the second inclined surface, and the through hole includes a fourth inclined surface matching and abutting against the third inclined surface 332.

[0056] In this embodiment, the reverse movement of the pressing sleeve 31 and the inserting rod 34 is achieved by the cooperation of the inclined surfaces. Figure 3 As shown, when the pressing sleeve 31 moves toward the fixed rod 1, due to the cooperation between the first inclined surface 331 and the second inclined surface, the connecting member 33 will move in the direction of the arrow in the figure. During the movement of the connecting member 33, due to the cooperation between the third inclined surface 332 and the fourth inclined surface, the insert rod 34 can only move toward the side away from the fixed rod 1 under the limitation of the fixed rod 1 to disengage from the positioning hole 21.

[0057] In one embodiment, a guide groove for guiding the moving direction of the pressing sleeve 31 is provided on the fixing rod 1 .

[0058] In one embodiment, a guide assembly is also fixed to the fixing rod 1, and the guide assembly includes a first guide plate 51, a distance is left between the first guide plate 51 and the circuit board 100, and a first guide groove is provided on the first guide plate 51 for the solid state drive 200 to pass through. The guide assembly also includes a second guide plate 52, the second guide plate 52 is fixed to the circuit board 100, and a second guide groove surrounding the test socket is provided on the second guide plate 52.

[0059] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
