Description
Technical Field
[0001] The utility model relates to the technical field of hard disk testing equipment, in particular to a hard disk testing fixture. 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 advantages such as 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 necessary to manually align the SSD with the test socket, insert it into the test socket after confirmation, and then unplug the SSD after the test is completed. However, the SSD is directly plugged into the test socket, which is not convenient for alignment, and the stability of the SSD clamping is poor. At the same time, because different models of SSDs have different thicknesses, a test fixture is required that can meet the testing of SSDs of different thicknesses. Utility Model Content
[0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide a hard disk test fixture that can stably clamp hard disks of different sizes.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a hard disk test fixture, including a circuit board, the circuit board is provided with at least one test socket, the hard disk test fixture also includes:
[0005] A guide frame, the guide frame is fixed to a side of the circuit board where the test socket is provided, and the guide frame is provided with a guide channel corresponding to the test socket;
[0006] A clamping assembly, the clamping assembly is used to clamp the hard disk onto the test socket, the clamping assembly comprises:
[0007] A fixing frame, wherein the fixing frame is fixed on one side of the guide frame;
[0008] A swing frame, the swing frame is hinged to an end of the fixed frame away from the circuit board, and the swing frame can swing along the fixed frame;
[0009] A torsion spring is sleeved on the fixing frame, and the torsion spring provides a force for the swing frame to swing toward the hard disk, so as to press the hard disk tightly against the test socket.
[0010] The beneficial effect of the utility model is that a clamping assembly is added, and the clamping assembly is a swinging structure, which uses the elastic force of the torsion spring to drive the swingable swing frame to swing toward the hard disk. When the swing frame abuts against the hard disk, the torsion spring is still in a compressed state, providing a force to press the swing frame on the hard disk, thereby confining the hard disk between the swing frame and the circuit board.
[0011] Furthermore, the swing frame comprises:
[0012] A connecting arm, wherein the connecting arm is sleeved on the swing frame and can swing along the swing frame;
[0013] A clamping plate is fixed to the end of the connecting arm away from the swing frame, and the clamping plate can abut against the hard disk.
[0014] The swing frame is hinged to the fixed frame through a connecting arm, and the clamping plate is used for clamping the hard disk.
[0015] Furthermore, a groove corresponding to the test socket is formed on the clamping plate, and when the clamping plate clamps the hard disk, the end of the hard disk is embedded in the groove.
[0016] The groove can limit the position of the hard disk in the direction of the hard disk thickness and the direction of the hard disk length.
[0017] Furthermore, at least one torsion spring is provided, and each torsion spring comprises a torsion spring body and support arms at both ends of the torsion spring body, the torsion spring body is sleeved on the guide frame, and the two support arms are respectively abutted against or fixed to the fixed frame and the swing frame.
[0018] Furthermore, each of the guide channels is symmetrically arranged relative to the vertical plane where the pressing plate is located. At this time, the force application point of the pressing plate on the hard disk is located at the center of the hard disk end, so that the pressure is more uniform and the hard disk is prevented from tilting.
[0019] Furthermore, each of the guide channels is slidably connected with a partition, which partitions the guide channels in the thickness direction of the hard disk. The partition can leave the guide channel under the pressure of the hard disk and enter the guide channel under the push of the reset member.
[0020] The addition of dividers allows a guide channel to provide guidance for hardware of varying thicknesses.
[0021] Furthermore, two partitions are arranged in one of the guide channels, and the two partitions are arranged at intervals along the width direction of the hard disk and can move along the width direction of the hard disk;
[0022] The guide frame is provided with a clearance groove which is in communication with the guide channel, the partition slides along the clearance groove, and the reset member is embedded in the clearance groove.
[0023] When the partition extends to the guide channel, it divides the guide channel, and a hard disk with a smaller thickness can be inserted at this time, and the partition is located above the hard disk. However, when a hard disk with a larger thickness is inserted, the partition can be directly pushed to move, and the partition leaves the guide channel and is completely embedded in the clearance groove, which will not interfere with the thick hard disk.
[0024] Furthermore, the partition has an inclined surface, which can abut against the hard disk and slide toward a side away from the hard disk under the pressure of the hard disk.
[0025] The inclined surface facilitates the insertion of the hard disk on the one hand, and can also be used to push the partition to move on the other hand.
[0026] Furthermore, the reset member is a spring, one end of the spring abuts against the bottom of the yield groove, and the other end abuts against the partition, and the spring is in a continuously compressed state when the hard disk squeezes the partition. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] 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.
[0036] See attached Figure 1 As shown, a hard disk 4 test fixture of the utility model includes a circuit board 1, and at least one test socket 11 is provided on the circuit board 1. When the hard disk 4 is inserted into the test socket 11 and docked with the test socket 11, data interaction between the test socket 11 and the hard disk 4 can be realized.
[0037] However, if the test socket 11 is relied on alone, the connection between the circuit board 1 and the hard disk 4 is unstable, especially when the hard disk 4 needs to be tested in an incubator, the hard disk 4 is easily loosened due to the wind in the incubator, affecting the test. Therefore, in this embodiment, the hard disk 4 test fixture also includes a guide frame 2 and a clamping assembly 3. The guide frame 2 provides guidance for the insertion of the hard disk 4, facilitates the docking of the hard disk 4 and the test socket 11, and reduces the deviation during the connection. The clamping assembly 3 is used to clamp the hard disk 4 on the test socket 11. At this time, the hard disk 4 can be stably plugged into the test socket 11 and is not easy to loosen.
[0038] See attached Figure 1 and attached Figure 3 As shown, the guide frame 2 is fixed to a side of the circuit board 1 where the test socket 11 is provided, and a guide channel 21 corresponding to the test socket 11 is provided on the guide frame 2. The hard disk 4 slides along the guide channel 21 and then plugs into the test socket 11.
[0039] See attached Figure 1 As shown, the pressing assembly 3 includes a fixed frame 31, a swing frame 32 and a torsion spring 33. The fixed frame 31 is fixed to one side of the guide frame 2. The swing frame 32 is hinged to one end of the fixed frame 31 away from the circuit board 1, and the swing frame 32 can swing along the fixed frame 31. The torsion spring 33 is sleeved on the fixed frame 31, and the torsion spring 33 provides a force for the swing frame 32 to swing toward the hard disk 4, so as to press the hard disk 4 against the test socket 11.
[0040] In this embodiment, a clamping assembly 3 is added. The clamping assembly 3 is a swinging structure, and uses the elastic force of the torsion spring 33 to drive the swinging frame 32 to swing toward the hard disk 4. When the swinging frame 32 abuts against the hard disk 4, the torsion spring 33 is still in a compressed state, providing a force for the swinging frame 32 to press on the hard disk 4, so as to confine the hard disk 4 between the swinging frame 32 and the circuit board 1.
[0041] See attached Figure 2 As shown, the fixing frame 31 is fixed to the outside of the circuit board 1. The fixing frame 31 is a door-shaped structure, including two cross bars 311 and a vertical bar 312. The cross bars 311 are connected to the external structure, and the vertical bar 312 is fixed to the side of the cross bars 311 away from the circuit board 1. Figure 2 As shown by the arrow in , the swing frame 32 swings along the vertical rod 312, that is, the swing frame 32 swings with the vertical rod 312 as the central axis.
[0042] The swing frame 32 includes a connecting arm 321 and a pressing plate 322. The connecting arm 321 is sleeved on the swing frame 32 and can swing along the swing frame 32. The pressing plate 322 is fixed to the end of the connecting arm 321 away from the swing frame 32. The pressing plate 322 can abut against the hard disk 4. The swing frame 32 is hinged to the fixed frame 31 through the connecting arm 321. The pressing plate 322 is used to press the hard disk 4.
[0043] See attached Figure 2 As shown, two connecting arms 321 are provided, and the clamping plate 322 is fixed between the two connecting arms 321, and the two connecting arms 321 are sleeved on the fixing frame 31. The clamping plate 322 is arranged along the vertical direction (Z direction), and the two connecting arms 321 provide stable support for the clamping plate 322 along the extension direction of the clamping plate 322.
[0044] In one embodiment, the number of connecting arms 321 may be one, three, etc., depending on actual needs.
[0045] In one embodiment, see the attached Figure 2 As shown, the clamping plate 322 is provided with a groove 3221 corresponding to the test socket 11, but when the clamping plate 322 clamps the hard disk 4, the end of the hard disk 4 is embedded in the groove 3221. The arrangement of the groove 3221, the groove bottom and the hard disk 4 abut against each other, can limit the position of the hard disk 4 in the length direction (X direction) of the hard disk 4, and at the same time, due to the upper side wall and the lower side wall of the groove 3221, the position of the hard disk 4 is limited in the thickness direction (Z direction) of the hard disk 4.
[0046] Because the test fixture can be used to test hard disks 4 of different thicknesses, the length of the groove 3221 in the Y direction is not less than the maximum thickness of the hard disk 4 that can be tested. At this time, even the end of the hard disk 4 with the largest thickness can be inserted into the groove 3221, and of course the end of the hard disk 4 with a smaller thickness can also be inserted into the groove 3221.
[0047] At least one torsion spring 33 is provided, and each torsion spring 33 includes a torsion spring body 331 and arms 332 at both ends of the torsion spring body 331. The torsion spring body 331 is sleeved on the guide frame 2, and the two arms 332 are respectively against or fixed to the fixed frame 31 and the swing frame 32. When the hard disk 4 needs to be inserted, the external force pulls the swing frame 32 to swing toward the circuit board 1. At this time, the torsion spring 33 is continuously compressed. When the hard disk 4 is inserted, the external force is cancelled, and the swing frame 32 quickly resets under the elastic force of the torsion spring 33, swings toward the circuit board 1, and the pressing plate 322 is pressed against the hard disk 4.
[0048] The connecting arm 321 is sleeved on the vertical rod 312, one arm 332 is plugged on the vertical rod 312, and the other arm 332 is plugged on the connecting arm 321. At this time, the torsion spring 33 can also limit the position of the swing frame 32 to prevent the swing frame 32 from moving up and down along the vertical rod 312.
[0049] In one embodiment, each of the guide channels 21 is symmetrically arranged relative to the vertical plane where the clamping plate 322 is located. That is, the clamping plate 322 is pressed against the middle position of the end of the hard disk 4. At this time, the clamping plate 322 applies a force to the middle position of the hard disk 4, and the insertion of the hard disk 4 is more stable.
[0050] In one embodiment, see the attached Figure 2 As shown, the guide frame 2 includes two guide plates 22 spaced apart along the width direction (Y direction) of the hard disk 4, and the two guide plates 22 are stacked. A U-shaped guide groove is provided on the guide plate 22, and a pair of guide grooves form a guide channel 21.
[0051] In one embodiment, because the guide channel 21 needs to guide hard disks 4 of different thicknesses, it is used for testing hard disks 4 of different thicknesses. Each guide channel 21 is slidably connected with a partition 23, and the partition 23 partitions the guide channel 21 in the thickness direction of the hard disk 4. The partition 23 can leave the guide channel 21 under the pressure of the hard disk 4, and enter the guide channel 21 under the push of the reset member 24.
[0052] See attached Figure 3 and attached Figure 4 As shown, two separators 23 are arranged in one guide channel 21, and the two separators 23 are arranged at intervals along the width direction of the hard disk 4 and can move along the width direction of the hard disk 4. The guide frame 2 is provided with a clearance groove 221 that is in communication with the guide channel 21, and the separator 23 slides along the clearance groove 221, and the reset member 24 is embedded in the clearance groove 221. That is, the guide groove of each guide plate 22 corresponds to a clearance groove 221, and the separator 23 is slidably connected in the clearance groove 221.
[0053] When the partition 23 extends to the guide channel 21, the guide channel 21 is divided. At this time, a hard disk 4 with a smaller thickness can be inserted, and the partition 23 is located above the hard disk 4. However, when a hard disk 4 with a larger thickness is inserted, the partition 23 can be directly pushed to move. At this time, the partition 23 leaves the guide channel 21 and is completely embedded in the clearance groove 221, which will not interfere with the hard disk 4 with a larger thickness. Through the setting of the partition 23, the guide channel 21 can guide two hard disks 4 of different thicknesses. Usually, there are two thicknesses, so a pair of partitions 23 can meet the use requirements.
[0054] See attached Figure 3 and attached Figure 4As shown in FIG. 1 , the partition 23 has an inclined surface 231, which can abut against the hard disk 4 and slide toward the side away from the hard disk 4 under the pressure of the hard disk 4. The inclined surfaces 231 of the two partitions 23 form a flared structure, which is convenient for inserting the hard disk 4. The insertion direction of the hard disk 4 is shown in FIG. Figure 4 As shown by the hollow arrow in FIG. Utilizing the cooperation between the inclined surface 231 and the hard disk 4, the hard disk 4 can push the partition 23 to move horizontally.
[0055] In one embodiment, the reset member 24 is a spring, one end of which abuts against the bottom of the clearance groove 221, and the other end abuts against the partition 23. The spring is in a continuously compressed state when the hard disk 4 presses the partition 23. When the partition 23 is not pressed by the hard disk 4, the elastic force of the spring drives part of the partition 23 to extend into the guide channel 21 to separate the guide channel 21. When the partition 23 completely enters the clearance groove 221 under the pressure of the hard disk 4, the spring is continuously compressed, and the spring accumulates force to drive the partition 23 to reset.
[0056] 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.
