Description
Technical Field
[0001] The utility model relates to the technical field of solid state hard disk testing equipment, in particular to a fixing device used for solid state hard disk testing. Background Art
[0002] At present, after the production of solid-state drives is completed, it is necessary to perform performance tests on the finished solid-state drives to detect their read and write capabilities and storage capabilities, so as to determine whether the produced solid-state drives meet the requirements. When testing solid-state drives, they are usually plugged into a circuit board, and the test machine sends read and write data to the solid-state drive for performance testing. However, on existing circuit boards, the solid-state drive is directly plugged in through the interface on the circuit board, which has poor stability and is prone to deviation during plugging, affecting operation. Even if a guide structure is set on some circuit boards, the existing guide structure is prone to damage the solid-state drive, or it only serves as a guide and cannot fix the solid-state drive. Utility Model Content
[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a fixing device for solid state hard disk testing, adding a fixing component that can guide the solid state hard disk, effectively protect the solid state hard disk and limit the fixed hard disk.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a fixing device for solid state hard disk testing, comprising:
[0005] A circuit board, wherein at least one interface is provided on the circuit board, and the interface can be connected and conducted with the solid state drive;
[0006] A fixing component, wherein the fixing component is arranged corresponding to the interface, the fixing component seat is connected to the circuit board and surrounds the corresponding interface, the fixing component includes a support member and a flexible member sleeved outside the support member, the flexible member forms a fixing cavity with openings at both ends along a first direction, part of the side wall of the fixing cavity can contact the solid state drive, and when the solid state drive is inserted into the fixing cavity, the flexible member can be squeezed to produce deformation.
[0007] The beneficial effects of the utility model are:
[0008] 1. Add a fixing component to guide the solid-state hard disk before inserting it into the interface and to limit the solid-state hard disk after insertion to prevent it from falling.
[0009] 2. The fixing component adopts a combined structure of a support member and a flexible member. The support member supports the flexible member, and the flexible member is in flexibly contact with the solid state drive, which will not damage the solid state drive. At the same time, the flexible member uses its own elastic deformation energy to compress and fix the solid state drive.
[0010] Furthermore, the fixed cavity includes an upper side wall and a lower side wall spaced apart along the second direction, and the flexible member is provided with a clearance groove located directly above the upper side wall. The solid state hard disk abuts against the lower side wall and can squeeze the upper side wall toward the position of the clearance groove to cause deformation.
[0011] A clearance groove is arranged above the upper side wall to provide space for deformation of the upper side wall. When the solid state hard disk is inserted into the fixing cavity, the upper side wall can be squeezed, and the upper side wall moves toward the clearance groove to deform, and because of its own elastic force, it always has a downward reset force, so it can clamp the solid state hard disk in the second direction.
[0012] Furthermore, the upper side wall includes a clamping portion and connecting portions located on both sides of the clamping portion, the height position of the clamping portion is lower than the height position of the connecting portion, and there is an arc transition between the clamping portion and the connecting portion.
[0013] The upper side wall forms an elastic arm structure, the solid state hard disk will squeeze the pressing part to deform, and the connecting part will pull the pressing part to reset.
[0014] Furthermore, the minimum vertical distance between the contact surface between the pressing portion and the solid state hard disk and the contact surface between the lower side wall and the solid state hard disk is not greater than the thickness of the solid state hard disk;
[0015] The minimum vertical distance between the contact surface between the connecting portion and the solid state hard disk and the contact surface between the lower side wall and the solid state hard disk is greater than the thickness of the solid state hard disk.
[0016] To ensure that when the solid state drive is inserted into the fixed cavity, the clamping part will be squeezed but will not contact the connecting part. The connecting part stores force for the clamping part to reset downward, and always applies downward pressure on the upper end surface of the solid state drive to ensure that the solid state drive is fixed between the upper side wall and the lower side wall.
[0017] Furthermore, the side wall further includes a left wall and a right wall spaced apart and parallel to each other along the third direction, and the distance between the left wall and the right wall is equal to the width of the solid state drive. When the solid state drive is inserted into the fixing cavity, it can abut against the left wall and the right wall, and the left wall and the right wall limit the solid state drive in the third direction.
[0018] Furthermore, a groove is provided at the connection between the left and right walls and the lower wall, and the groove is connected to the fixed cavity. On the one hand, the groove provides space for the extension of the fixed cavity, which is convenient for the insertion of the solid state drive. On the other hand, the corner of the solid state drive is inserted into the groove position without contacting the flexible part, thereby avoiding damage to the flexible part.
[0019] Furthermore, the flexible member is made of silicone material, which is elastic and has good thermal conductivity, thus facilitating heat dissipation of the solid state drive.
[0020] Furthermore, the support member is detachably connected to the circuit board, and the flexible member is provided with a plug-in slot matching the support member. After the support member is fixed on the circuit board, the flexible member is sleeved on the support member.
[0021] Furthermore, the support member comprises:
[0022] A fixing plate, the fixing plate is fixedly connected to the circuit board, and the fixing plate is provided with a through slot for the interface to pass through;
[0023] A bottom plate, the bottom plate is fixed to the fixing plate and is located below the fixing plate;
[0024] The side panels are provided with two and both are fixed to the fixing plate, and the two side panels are spaced apart along the third direction.
[0025] The support member provides a supporting force for the flexible member, and no support member is arranged above the fixed plate, so that the arrangement of the give way groove is not affected while the supporting force is met. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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.
[0038] See attached Figure 1 and attached Figure 6 As shown, the fixture for testing a solid state drive of the utility model includes a circuit board 100, on which at least one interface 1a is provided, and the interface 1a can be connected and conducted with a solid state drive 300, and a plug is provided at the end of the solid state drive 300, and a gold finger is provided on the plug, and when the plug is inserted into the interface 1a, the solid state drive 300 is conducted through the gold finger. However, since the solid state drive 300 usually has a certain length (Y direction), the solid state drive 300 is not very stable if it only relies on the plug-in connection with the interface 1a. Moreover, when the solid state drive 300 is directly inserted into the interface 1a, it may not be aligned with the interface 1a, causing damage to the interface 1a or the gold finger.
[0039] Therefore, the fixing device in this embodiment further includes a fixing component 200 , and the fixing component 200 is used to guide and limit the solid state hard disk 300 plugged into the circuit board 100 .
[0040] See attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the fixing component 200 is arranged corresponding to the interface 1a, the fixing component seat is connected to the circuit board 100 and surrounds the corresponding interface 1a, the fixing component 200 includes a support member 1 and a flexible member 2 sleeved on the outside of the support member 1, the flexible member 2 forms a fixing cavity 21 with openings at both ends along a first direction (Y direction), part of the side wall of the fixing cavity 21 can contact the solid state drive 300, and when the solid state drive 300 is inserted into the fixing cavity 21, the flexible member 2 can be squeezed to produce deformation.
[0041] In this embodiment, a fixing component 200 is added to guide the solid state drive 300 before being inserted into the interface 1a, and to limit the solid state drive 300 after being inserted to prevent the solid state drive 300 from falling. The fixing component 200 adopts a combined structure of a support member 1 and a flexible member 2. The support member 1 supports the flexible member 2, and the flexible member 2 is in flexible contact with the solid state drive 300, which will not damage the solid state drive 300. At the same time, the flexible member 2 can compress and fix the solid state drive 300 by its own elastic deformation.
[0042] See attached Figure 4 and attached Figure 5As shown, the fixed cavity 21 includes an upper side wall 211, a lower side wall 212, a left side wall 213 and a right side wall 214, and the upper side wall 211, the lower side wall 212, the left side wall 213 and the right side wall 214 are sequentially connected to form the fixed cavity 21. The upper side wall 211 and the lower side wall 212 are spaced apart along the second direction (Z direction), and the upper side wall 211 is located above the lower side wall 212. The flexible member 2 is provided with a clearance groove 22 located just above the upper side wall 211, and the solid state drive 300 abuts against the lower side wall 212 and can squeeze the upper side wall 211 toward the position of the clearance groove 22 to produce deformation.
[0043] In this embodiment, a clearance groove 22 is provided above the upper side wall 211 to provide space for deformation of the upper side wall 211. When the solid state hard disk 300 is inserted into the fixing cavity 21, the upper side wall 211 can be squeezed, and the upper side wall 211 moves toward the clearance groove 22, deforms, and because of its own elastic force, it always has a downward return force, so it can clamp the solid state hard disk 300 in the Z direction.
[0044] In one embodiment, see the attached Figure 5 As shown, the upper side wall 211 includes a pressing portion 211a and connecting portions 211b located on both sides of the pressing portion 211a. The height of the pressing portion 211a is lower than the height of the connecting portion 211b, and there is an arc transition between the pressing portion 211a and the connecting portion 211b. The upper side wall 211 forms an elastic arm structure, the solid state drive 300 will squeeze the pressing portion 211a to deform, and the connecting portion 211b will pull the pressing portion 211a to reset. The lower side wall 212 is a flat plate structure.
[0045] The minimum vertical distance h1 between the contact surface of the pressing part 211a and the solid state drive 300 and the contact surface of the lower side wall 212 and the solid state drive 300 is not greater than the thickness of the solid state drive 300; the minimum vertical distance h2 between the contact surface of the connecting part 211b and the solid state drive 300 and the contact surface of the lower side wall 212 and the solid state drive 300 is greater than the thickness of the solid state drive 300. That is to ensure that when the solid state drive 300 is inserted into the fixing cavity 21, it will inevitably squeeze the pressing part 211a, but will not contact the connecting part 211b. The connecting part 211b accumulates force for the pressing part 211a to reset downward, and always applies a downward pressure F (attached) on the upper end surface of the solid state drive 300. Figure 4 As shown), the solid state drive 300 is ensured to be fixed between the upper side wall 211 and the lower side wall 212, and the solid state drive 300 is limited in the Z direction.
[0046] The left side wall 213 and the right side wall 214 are parallel and spaced apart along the third direction (X direction), and the distance between the left side wall 213 and the right side wall 214 is equal to the width of the solid state drive 300. When the solid state drive 300 is inserted into the fixing cavity 21, it can abut against the left side wall 213 and the right side wall 214, and the left side wall 213 and the right side wall 214 limit the solid state drive 300 in the X direction.
[0047] A groove 215 is provided at the connection between the left side wall 213 and the right side wall 214 and the lower side wall 212, and the groove 215 is in conduction with the fixed cavity 21. The groove 215 is arc-shaped, and on the one hand, the groove 215 provides space for the extension of the fixed cavity 21, which is convenient for the insertion of the solid state drive 300, and on the other hand, the corner of the solid state drive 300 is inserted into the groove 215 position without contacting the flexible member 2, thereby avoiding damage to the flexible member 2 by the corner.
[0048] The flexible member 2 is made of silicone material, which is elastic and has good thermal conductivity, thus facilitating heat dissipation of the solid state drive 300 .
[0049] In one embodiment, the support member 1 is detachably connected to the circuit board 100, and the support member 1 can be connected to the circuit board 100 by bolts. The flexible member 2 is provided with a plug-in slot 23 matching the support member 1. After the support member 1 is fixed on the circuit board 100, the flexible member 2 is mounted on the support member 1. The flexible member 2 now forms a double-layer structure, with the outer layer located outside the support member 1 to protect the support member 1, and the inner layer wraps the solid state drive 300 to protect and limit the position of the solid state drive 300.
[0050] See attached Figure 6 As shown, the support member 1 includes a fixed plate 11, a bottom plate 12 and a side plate 13. The fixed plate 11 is fixedly connected to the circuit board 100, and a through slot for the interface 1a to pass through is provided on the fixed plate 11. The bottom plate 12 is fixed to the fixed plate 11 and is located below the fixed plate 11. Two side plates 13 are provided and are both fixed to the fixed plate 11. The two side plates 13 are spaced apart along the X direction. The support member 1 provides a supporting force for the flexible member 2. At the same time, there is no support member 1 above the fixed plate 11. While satisfying the supporting force, the setting of the clearance slot 22 is not affected.
[0051] See attached Figure 1 As shown, a plurality of interfaces 1a are arranged at intervals along the Y direction on the circuit board 100, and a fixing component 200 surrounding the interface 1a is arranged at each interface 1a, which is used to provide guidance for the insertion of the solid state drive 300 and to limit the inserted solid state drive 300. The structure of the flexible component 2 in the fixing component 200 effectively protects the solid state drive 300, and facilitates the heat dissipation of the solid state drive 300 while being able to guide and limit the solid state drive 300.
[0052] 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.
