[0002] After the production of the solid-state drive is completed, it is necessary to perform a performance test on the solid-state drive to detect the read, write and storage capabilities of the solid-state drive. The solid-state drive is usually plugged into a test fixture for performance testing. The test fixture usually includes a circuit board, and the circuit board is provided with an interface that can be connected to and plugged into the solid-state drive. Directly plugging in the solid-state drive through the interface on the circuit board has poor stability, especially when superimposed environmental testing. That is, when the test fixture is placed in a high and low temperature box and environmental testing is performed at the same time, air will be blown in the high and low temperature box. At this time, the solid-state drive is fixed only by the interface, which obviously cannot meet the performance test under blowing. Therefore, a test fixture is needed that can improve the stability of the solid-state drive clamping and can meet the testing of solid-state drives of different sizes. Utility Model Content

[0040] 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.

[0041] See attached Figure 1 As shown, different models of SSDs 1 are usually the same in width (X direction), but different in length (Y direction). All SSDs 1 have a plug 11 at one end along the length direction, which needs to be plugged into the socket 21, and a circular groove 12 at the other end.

[0042] The test fixture for the solid state hard disk 1 of the utility model can be used to fix solid state hard disks of different sizes and can stably clamp the solid state hard disk 1. Figure 2 As shown, the test fixture includes a circuit board 2, on which at least one socket 21 for plugging with a solid state drive 1 is provided, and the sockets 21 are arranged at intervals along the Z direction, that is, a plurality of solid state drives 1 can be plugged into one circuit board 2. During testing, the plug 11 of the solid state drive 1 needs to be inserted into the socket 21, and the external controller sends a test instruction toward the solid state drive 1 through the socket 21.

[0043] See attached Figure 2As shown, the test fixture also includes a jig 3 and an elastic positioning member 4, the jig 3 is arranged corresponding to the socket 21, and each of the jigs 3 is detachably connected to the circuit board 2. The jig 3 includes a plug-in portion 31 extending along the length direction of the solid state drive 1, and the plug-in portion 31 is provided with a plurality of fixed sockets 311 spaced apart along the first direction. The elastic positioning member 4 is detachably connected to the plug-in portion 31 and can be fixed in the fixed socket 311, and the elastic positioning member 4 fixed in the fixed socket 311 can abut against the end of the solid state drive 1, and the solid state drive 1 is pressed tightly at the socket 21.

[0044] In this embodiment, the test fixture is additionally provided with a jig 3 and an elastic positioning member 4. The plug-in portion 31 of the jig 3 provides a fixed socket 311 for the elastic positioning member 4. The elastic positioning member 4 is detachably connected to the fixed socket 311, but when fixed in the fixed socket 311, the solid-state hard disk 1 can be confined between the elastic positioning member 4 and the circuit board 2. At the same time, due to the flexible material of the elastic positioning member 4, it is easy to deform and will not have a hard contact with the solid-state hard disk 1, which can effectively protect the solid-state hard disk 1. Furthermore, a plurality of fixed sockets 311 are spaced apart in the first direction, and the elastic positioning member 4 is plugged into different fixed sockets 311 to achieve the limitation of fixed hard disks of different sizes.

[0045] In one embodiment, see the attached Figure 3 As shown, the elastic positioning member 4 includes a cylindrical fixing portion 41, which passes through the fixing plug hole 311 and is plugged into the fixing socket 21. The fixing portion 41 is provided with a first annular groove 411 along the circumferential direction, and the end of the solid state drive 1 is embedded in the first annular groove 411.

[0046] The position of the fixing portion 41 is fixed by plugging the fixing slot with the top portion. The first annular groove is provided to increase the contact area between the elastic positioning member 4 and the solid state hard disk 1. The solid state hard disk 1 can be limited in both the Z direction and the Y direction.

[0047] In one embodiment, the fixing portion 41 is further provided with a second annular groove body 412 spaced apart from the first annular groove body 411 along the circumferential direction, and a portion of the plug-in portion 31 at the fixing plug hole 311 is embedded in the second annular groove body 412. The second annular groove is provided to increase the contact area between the elastic positioning member 4 and the plug-in portion 31, and the elastic positioning member 4 can be limited in the Z direction, the Y direction, and the X direction.

[0048] See attached Figure 4As shown, the diameter of the fixing portion 41 is larger than the diameter of the fixing slot, the first annular groove and the second annular groove are arranged along the Z direction, and the fixing portion 41 is divided into an upper portion 413, a middle portion 414 and a lower portion 415. The first annular groove is located between the upper portion 413 and the middle portion 414, and the second annular groove is located between the middle portion 414 and the lower portion 415. The vertical distance between the upper portion 413 and the middle portion 414 is equal to the thickness of the groove 12 of the solid state drive 1. The solid state drive 1 is clamped between the upper portion 413 and the middle portion 414, and the groove 12 abuts against the bottom of the first annular groove. The vertical distance between the middle portion 414 and the lower portion 415 is equal to the thickness of the plug-in portion 31, and the plug-in portion 31 is clamped between the middle portion 414 and the lower portion 415. The bottom diameter of the second annular groove is smaller than the diameter of the fixing slot.

[0049] See attached Figure 3 As shown, the elastic positioning member 4 further includes an introduction portion 42 of a conical structure, and the introduction portion 42 is located at the end of the fixing portion 41 close to the second annular groove body 412. The introduction portion 42 and the fixing portion 41 are arranged along the Z direction, and the diameter of the large circular surface of the introduction portion 42 is the same as the diameter of the fixing portion 41. The introduction portion 42 of the conical structure is easy to insert into the jack.

[0050] In one embodiment, the elastic positioning member 4 is provided with a clearance groove 43 along the end of the introduction portion 42 away from the fixing portion 41 toward the fixing portion 41, the clearance plug is coaxially arranged with the fixing portion 41, and the clearance plug extends to the second annular groove body 412 and is located below the first annular groove body 411. That is, for the second annular groove body 412 and the introduction portion 42 that need to be formed, there is a clearance groove 43 in the center, and the elastic positioning member 4 is easily deformed and reduced in the second annular groove body 412 and the tapered portion under external force. However, for the first annular groove that needs to provide support force, there is no need for the clearance groove 43, and the clearance groove 43 will not extend upward to the first annular groove.

[0051] In one embodiment, the elastic positioning member 4 is a silicone member, which has elasticity and is easy to be processed by injection molding.

[0052] In one embodiment, see the attached Figure 5 As shown, the plug-in portion 31 is also provided with an introduction hole 312, which is arranged corresponding to the fixed hole 311 and is larger than the diameter of the corresponding fixed hole 311. The introduction hole 312 may have the same diameter as the fixed portion 41 or slightly larger than the diameter of the fixed portion 41. The introduction hole 312 is connected to the corresponding fixed hole 311 and is located on the side of the fixed hole 311 close to the solid state drive 1. The elastic positioning member 4 is inserted from the introduction hole 312 and moves and is fixed in the corresponding fixed hole 311.

[0053] See attached Figure 6As shown, the introduction socket 312 and the fixed socket 311 form an 8-shaped structure, and the connection between the two forms a connecting channel 313. The connecting channel 313 includes two vertical surfaces, and the two vertical surfaces are spaced along the X direction. The vertical distance between the two vertical surfaces is less than the diameter of the fixing portion 41 and greater than the diameter of the bottom of the second annular groove. In this way, the elastic positioning member 4 is inserted from the introduction socket 312, and then moved from the connecting channel 313 to the fixed socket 311. Due to the size limitation, the elastic positioning member 4 is fixed in the fixed socket 311. At this time, when it is necessary to fix the solid-state hard disk 1 of different sizes, it is necessary to remove the elastic positioning member 4 from the introduction socket 312, and then insert it into the introduction socket 312 of another size corresponding to the solid-state hard disk 1, and then move the flexible fixing member to the corresponding fixed socket 311.

[0054] In one embodiment, see the attached Figure 7 and attached Figure 8 As shown, the plug-in portion 31 is also provided with an introduction hole 312, which is located between two adjacent fixed holes 311, and the diameter of the introduction hole 312 is larger than the diameter of the fixed holes 311. The introduction hole 312 is connected to the fixed holes 311 on both sides, and the elastic positioning member 4 is inserted from the introduction hole 312 and can be moved and fixed in any one of the fixed holes 311.

[0055] At this time, the fixed sockets 311 are connected to each other, and the user can move from one fixed socket 311 to any other fixed socket 311 .

[0056] In one embodiment, the introduction socket 312 may not be provided, and only the fixing socket 311 may be provided, and the elastic positioning member 4 may be plugged in and out of the fixing socket 311 by utilizing its own elasticity.

[0057] See attached Figure 8 and attached Figure 5 As shown, the fixture 3 also includes a limiting portion 32, which is located on the side of the plug-in portion 31 close to the circuit board 2. The limiting portion 32 includes a lifting surface 321 for lifting the solid state drive 1, and the lifting surface 321 is provided with limiting surfaces 322 that can abut against the side walls of the solid state drive 1 on both sides along the width direction of the solid state drive 1.

[0058] The lifting surface 321 is responsible for lifting the solid state drive 1, and the limiting surface 322 limits the position of the fixed hard disk in the X direction. Since the solid state drive 1 enters the limiting portion 32 from the top, the limiting surface 322 includes a vertical portion and an inclined portion 3221 located above the vertical portion. The two inclined portions 3221 are away from each other from bottom to top, that is, the inclined portions 3221 of the two limiting surfaces 322 form a flared structure, which is convenient for placing the solid state drive 1.

[0059] See attached Figure 5 and attached Figure 8 As shown, the lifting surface 321 is provided with at least one heat dissipation groove 3211 downward. That is, the lifting surface 321 is not a plane, and there is a gap between the lifting surface 321 and the lower end surface of the solid state drive 1 to facilitate heat dissipation of the solid state drive 1. This does not affect the lifting function, but is conducive to heat dissipation.

[0060] See attached Figure 5 As shown, the fixture 3 also includes a guide portion 33, which is located on the side of the limiting portion 32 close to the circuit board 2. The guide portion 33 is arranged around the socket 21, and the guide portion 33 forms a guide cavity 331 with openings at both ends along the length direction of the solid state drive 1.

[0061] In the embodiment, the fixture 3 is a whole and can be fixed on the circuit board 2 by bolts. The fixture 3 is made of antistatic material.

[0062] When fixing the solid-state hard disk 1, first insert the flexible fixing part into the fixing socket 311 corresponding to the size of the solid-state hard disk 1, and then place the solid-state hard disk 1 from top to bottom. The groove 12 at the end of the solid-state hard disk 1 is first inserted into the first annular groove, and then the other end of the solid-state hard disk 1 moves downward along the inclined portion 3221. At this time, the solid-state hard disk 1 is not inserted into the guide cavity 331. The flexible fixing part is formed by the extrusion of the solid-state hard disk 1 and swings toward the side away from the circuit board 2. After the solid-state hard disk 1 is docked with the guide cavity 331, the solid-state hard disk 1 is pushed horizontally (in the Y direction) toward the socket 21, and the flexible fixing part resets itself using its own elastic force. When the solid-state hard disk 1 is inserted into the socket 21, the flexible fixing part is also in a vertical state, pressing the solid-state hard disk 1 toward the circuit board 2, thereby fixing the solid-state hard disk 1.

[0063] 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.
