Description

Technical Field

[0001] This invention relates to the field of server testing technology, and more specifically to a test fixture. Background Technology

[0002] Server motherboards typically support PCIe (Peripheral Component Interconnect Express) card slots. These slots are used to install expansion cards such as network adapters, RAID cards, and graphics cards. PCIe cards provide high-speed data transmission and low-latency interfaces, enabling servers to connect various external devices and expand functionality. A riser card (also known as an expansion slot adapter card) is an auxiliary device used to provide additional PCIe slots on the server motherboard. Due to limited space on server motherboards, riser cards can separate PCIe slots for better organization and placement of expansion cards. The riser card sits between the motherboard and the expansion cards, connected via cables or sockets, allowing expansion cards to be installed in different locations to meet the server's needs.

[0003] Before server products leave the factory, bare-board debugging of the motherboard is typically required. This process is conducted in a laboratory environment to verify the motherboard's functionality and performance, and to ensure that all components and interfaces are functioning correctly. Bare-board debugging allows for the early detection and resolution of potential motherboard problems, ensuring the server possesses good performance and stability before leaving the factory. This helps improve product quality and user satisfaction, while reducing subsequent failures and repair work.

[0004] In server testing projects, debugging adapter cards and PCIe cards is a necessary step. PCIe cards are suspended above the motherboard, posing a significant risk of damage to the card itself and its contacts. Currently, while some testing setups provide simple fixation for the adapter cards, there is still a possibility that the adapter card may detach and be damaged. Summary of the Invention

[0083] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0084] The following is combined Figures 1-8This describes a test fixture for embodiments of the present invention. It should be noted that server motherboards typically support PCIe (Peripheral Component Interconnect Express) card slots, which are used to install expansion cards such as network adapters, RAID cards, and graphics cards. PCIe cards provide high-speed data transmission and low-latency interfaces, enabling servers to connect various external devices and expand functionality. A riser card (also known as an expansion slot adapter card) is an auxiliary device used to provide additional PCIe slots on the server motherboard. Due to limited space on the server motherboard, the riser card can separate the PCIe slots for better organization and arrangement of expansion cards. The riser card is located between the motherboard and the expansion cards, connected via cables or sockets, allowing the expansion cards to be installed in different locations to meet the server's needs.

[0085] Before server products leave the factory, bare board debugging of the motherboard is usually required. Test fixtures can perform necessary functional and performance tests on the server's motherboard, PCIe cards, and adapter cards to ensure that the server can operate normally and meet the requirements.

[0086] like Figure 1 as well as Figure 3 As shown, the test fixture 100 according to an embodiment of the present invention includes a test platform, a connecting plate 120, a connecting structure 130, and a locking structure 140.

[0087] Specifically, the motherboard 101 is detachably mounted on the test platform (not shown in the figure), the adapter card 102 is vertically mounted on the motherboard 101, and the PCIe card 104 is detachably connected to the adapter card 102. For example, the adapter card 102 may have a card slot, and the PCIe card 104 is pluggably mounted in the card slot. The connection board 120 is connected to the test platform and the PCIe card 104, and the position of the PCIe card 104 relative to the connection board 120 is adjustable. It should be noted that the connection board 120 can serve as a support structure for the PCIe card 104, and the relative position between the PCIe card 104 and the connection board 120 can be adjusted according to the server model and type.

[0088] The position of the PCIe card 104 relative to the connector 120 is adjustable, typically achieved using adjustment mechanisms or brackets. These designs allow for adjustment of the PCIe card 104's position during installation to achieve optimal connectivity and performance. For example, a PCIe extension buffer can be used: a PCIe extension buffer is an adjustable-length connector that allows the PCIe card 104 to be pushed away from or pulled closer to the connector 120. By adjusting the length of the extension buffer, the distance between the PCIe card 104 and the connector 120 can be changed. It is important to avoid applying excessive force or causing unstable connections when adjusting the position of the PCIe card 104.

[0089] Combination Figure 1 and Figure 3 As shown, the connecting structure 130 has a telescopic function, and one end of the connecting structure 130 is fixedly connected to the connecting plate 120, while the other telescopic end of the connecting structure 130 is detachably connected to the adapter card 102. The telescopic connecting structure 130 allows for adjustment of the position and distance of the PCIe card 104 as needed. This makes installation and connection more flexible and meets specific requirements.

[0090] See Figure 3 and Figure 4 As shown, locking structure 140 is connected to connecting structure 130 to lock the extension / retraction of connecting structure 130. Locking structure 140 is used to lock the extension / retraction of connecting structure 130 to ensure the stability and security of the connection. These locking structures 140 are typically designed to reliably secure connecting structure 130 and prevent accidental movement or loosening during use. Locking structure 140 can provide a stable locking force to test fixture 100, ensuring that connecting structure 130 does not move or loosen accidentally during use.

[0091] According to the embodiment of the present invention, the test fixture 100, by setting the connecting structure 130 as a component with telescopic function and using the locking structure 140 to lock the telescopic amount of the connecting structure 130, can adjust the telescopic amount of the connecting structure 130 as needed, and use the locking structure 140 to fix the connecting structure 130, thereby connecting the connecting structure 130 to different types of adapter cards 102, and thus fixing the adapter card 102 and the PCIE card 104. This gives the test fixture 100 the advantages of high flexibility and adjustability.

[0092] See Figure 1 and Figure 3As shown, according to some embodiments of the present invention, the connecting structure 130 includes a first sleeve 131 and a second sleeve 132. One end of the first sleeve 131 is fixed to the connecting plate 120, and the other end is open. The second sleeve 132 is located at the other end of the first sleeve 131 and passes through the first sleeve 131. The second sleeve 132 is telescopic relative to the first sleeve 131. When fixing the adapter card 102, the length of the connecting structure 130 is adjusted by pushing or pulling the second sleeve 132 to slide relative to the first sleeve 131, thereby adapting to the size of the adapter card 102.

[0093] See Figure 4 As shown, according to some embodiments of the present invention, the locking structure 140 includes a fixing component 150, a movable component 160, a connecting rope 170, and a locking member 180. The fixing component 150 is fixedly connected to the connecting structure 130, and the fixing component 150 may be connected to a first sleeve 131, or the fixing component 150 may be connected to a second sleeve 132. The movable component 160 is connected to the connecting structure 130 and is used to fix the adapter 102. There may be multiple movable components 160 to improve the stability of the adapter 102, wherein at least one movable component 160 is connected to the retractable other end of the connecting structure 130 and is adapted to move with the retractable other end of the connecting structure 130. Understandably, when there is one movable component 160, it is adapted to connect to the retractable other end of the connecting structure 130, and the fixed component 150 is adapted to connect to the fixed end of the connecting structure 130. When there are multiple movable components 160, the fixed component 150 can be connected to the fixed end of the connecting structure 130, or the fixed component 150 can be connected to the retractable other end of the connecting structure 130. The movable component 160 is detachably connected to the adapter card 102, for example, the movable component and the adapter card 102 can be snapped together or connected by a threaded connection.

[0094] like Figure 3 and Figure 4 As shown, there can be two movable components 160, one of which is located on the first sleeve 131 and the other on the second sleeve 132. When the second sleeve 132 slides relative to the first sleeve 131, the distance between the two movable components 160 changes to connect with the adapter card 102. This allows the test fixture 100 to accommodate adapter cards 102 of different sizes, improving the applicability of the test fixture 100.

[0095] One end of the connecting rope 170 is connected to the fixed component 150, and the other end is connected to the movable component 160. As the movable component 160 moves with the second sleeve 132, the distance between at least one movable component 160 and the fixed component 150 changes. The connecting rope 170 is adapted to wrap around or release from the fixed component 150 to accommodate changes in the distance between the fixed component 150 and the movable component 160. The locking member 180 is switchable between a locked position and an unlocked position relative to the fixed component 150. When the locking member 180 is in the locked position, it locks the connecting rope 170 so that the connecting rope 170 is relatively stationary with respect to the fixed component 150, thereby limiting the distance between the movable component 160 and the fixed component 150. When the locking member 180 is in the unlocked position, the connecting rope 170 is movable relative to the fixed component 150, and the distance between the movable component 160 and the fixed component 150 is variable.

[0096] See Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the fixing assembly 150 includes a first fixing post 151, a winding barrel 152, and a housing 155. One end of the first fixing post 151 is fixedly connected to the connecting structure 130. For example, the first fixing post 151 can be welded to the connecting structure 130, or the first fixing post 151 and the connecting structure 130 can be integrally formed. Figure 3 As shown, the first fixing post 151 can be welded onto the first sleeve 131.

[0097] The winding drum 152 is rotatably connected to the other end of the first fixing post 151. For example, the first fixing post 151 may be provided with a rotating shaft, and the winding drum 152 is loosely fitted onto the rotating shaft. The connecting rope 170 is adapted to be wound around the outer periphery of the winding drum 152, and the connecting rope 170 is stored or released through the winding drum 152. The housing 155 covers the outer periphery of the winding drum 152 and is fixedly connected to the first fixing post 151 to protect the winding drum 152 and prevent the winding drum 152 from getting stuck. The connecting rope 170 passes through the housing 155, and the other end of the connecting rope 170 is located outside the housing 155. The housing 155 may be provided with a groove or through hole for the connecting rope 170 to pass through.

[0098] The inner peripheral wall of the winding drum 152 is provided with a first engaging portion 153, and the outer peripheral wall of the locking member 180 is provided with a second engaging portion 185 that engages with the first engaging portion 153. The locking member 180 is movably connected to the housing 155, and the locking member 180 is movable between a locked position and an unlocked position along the axial direction of the winding drum 152. When the locking member 180 is in the locked position, the second engaging part 185 engages with the first engaging part 153, locking the winding drum 152 and keeping it relatively stationary with respect to the housing 155. The connecting rope 170 restrains the movable component 160, locking the relative position of the movable component 160 and the fixed component 150, thereby achieving the extension and retraction of the locking connection structure 130. When the locking member 180 is in the unlocked position, the second engaging part 185 disengages from the first engaging part 153, and the winding drum 152 becomes movable relative to the housing 155 to release or rewind the connecting rope 170. The relative position between the movable component 160 and the fixed component 150 can change.

[0099] See Figure 5 As shown, according to some embodiments of the present invention, the locking member 180 includes a central rod 181, a locking block 183, and a rotating part 184. The central rod 181 passes through the housing 155, is movable relative to the housing 155, and is adapted to move along the axial direction of the winding drum 152. The central rod 181 is a straight rod and extends along the axial direction of the winding drum 152, and is coaxial with the winding drum 152. The locking block 183 is fixed to the outer periphery of the central rod 181 and is located outside the housing 155. The locking block 183 is used to limit the relative rotation angle between the central rod 181 and the housing 155. When the central rod 181 moves relative to the housing 155, it drives the locking block 183 to move until it engages with the housing 155, thereby fixing the relative position of the central shaft and the housing 155. The locking block 183 and the intermediate rod 181 can be integrally formed, or the locking block 183 can be inserted through the intermediate rod 181, and the outer periphery of the intermediate rod 181 can be provided with protrusions to circumferentially position the locking block 183.

[0100] A rotating part 184 is fixed to the outer periphery of the intermediate rod 181 and is located inside the housing 155. The rotating part 184 and the engaging block 183 are spaced apart along the axial direction of the intermediate rod 181, and the distance between the rotating part 184 and the engaging block 183 is the travel range of the intermediate rod 181 (the second engaging part 185). The second engaging part 185 is provided on the rotating part 184. By pushing the intermediate rod 181 to move relative to the housing 155, the second engaging part 185 is driven to engage or disengage with the first engaging part 153. It can be understood that when the intermediate rod 181 moves toward the winding drum 152, the second engaging part 185 engages with the first engaging part 153. At this time, the engaging block 183 is engaged with the housing 155 to restrict the rotation of the intermediate shaft relative to the housing 155, thereby restricting the rotation of the rotating part 184. Since the second engaging part 185 is engaged with the first engaging part 153, the winding drum 152 is fixed and cannot rotate.

[0101] like Figure 4 As shown, in some embodiments, there are two movable components 160 and two connecting ropes 170, with each connecting rope 170 connected to each movable component 160 in a one-to-one correspondence. One connecting rope 170 is wound on the winding drum 152, and the other connecting rope 170 is wound on the rotating part 184. When the first engaging part 153 and the second engaging part 185 engage, the locking member 180 can lock both connecting ropes 170 at the same time, thereby locking the position of the two movable components 160.

[0102] See Figure 8 As shown, according to some embodiments of the present invention, the outer periphery of the locking block 183 is provided with a third engaging portion 182, the housing 155 is provided with a through hole 156, the intermediate rod 181 passes through the through hole 156, and the wall of the through hole 156 is provided with a fourth engaging portion 157 that engages with the third engaging portion 182. When the intermediate rod 181 moves toward the winding drum 152, the locking block 183 moves to fit into the housing 155, and the third engaging portion 182 and the fourth engaging portion 157 engage to fix the locking block 183, thereby preventing the intermediate rod 181 from rotating.

[0103] In some embodiments, the third engagement portion 182 may be a protrusion formed on the outer peripheral wall of the engaging block 183. There are multiple third engagement portions 182, which are spaced apart along the circumferential direction of the engaging block 183. The fourth engagement portion 157 may be a protrusion on the wall of the through hole 156. There are multiple fourth engagement portions 157, which are spaced apart along the circumferential direction of the through hole 156. The structure of the fourth engagement portion 157 is adapted to that of the third engagement portion 182.

[0104] According to some embodiments of the present invention, the winding drum 152 is provided with a positioning groove for defining the winding position of the connecting rope 170. The positioning groove can be a groove or a recess, located on the surface of the winding drum 152. One end of the connecting rope 170 can be fixed in the positioning groove. When the connecting rope 170 is wound onto the winding drum 152, the connecting rope 170 can automatically wind into the positioning groove to ensure that the connecting rope 170 is fixed in the corresponding position. Through the positioning groove, the connecting rope 170 can be accurately positioned and fixed, preventing movement or loosening during use. The design of the positioning groove can be determined according to specific needs, and its shape and size can be optimized according to the diameter and material selection of the connecting rope 170.

[0105] According to some embodiments of the present invention, the connecting rope 170 is an elastic rope. Thus, when it is necessary to remove the restriction of the movable component 160 or shorten the elongation of the connecting structure 130, the connecting rope 170 can automatically retract, avoiding interference with the movement of other components of the test fixture 100. In some embodiments, a torsion spring may be provided between the winding drum 152 and the housing 155, the torsion spring being used to drive the winding drum 152 to rotate in order to wind up the connecting rope 170.

[0106] See Figure 6 As shown, according to some embodiments of the present invention, the movable component 160 includes a second fixing post 161, a connecting rod 162, and a limiting component 163. The second fixing post 161 is adapted to be connected to the connecting structure 130. One end of the second fixing post 161 is fixedly connected to the other retractable end of the connecting structure 130. The second fixing post 161 can be welded to the other retractable end of the connecting structure 130, or the second fixing post 161 and the connecting structure 130 can be integrally formed. One end of the connecting rod 162 is fixedly connected to the second fixing post 161, and the other end of the connecting rod 162 is adapted to pass through the adapter 102. Figure 2 As shown, the adapter card 102 is provided with a through hole for fixing. When fixing the adapter card 102, the other end of the connecting rod 162 passes through the through hole on the adapter card 102.

[0107] The limiting component 163 is connected to the other end of the connecting rope 170. The limiting component 163 is switchable between an extended state and a limited state, and the connecting rope 170 is used to control the switching of the limiting component 163 between the extended state and the limited state. The limiting component 163 is connected to the connecting rod 162. When the limiting component 163 is in the extended state, the limiting component 163 is adapted to follow the connecting rod 162 through the adapter 102. When the limiting component 163 is in the limited state, a portion of the structure of the limiting component 163 forms a raised structure, thereby fixing the adapter 102.

[0108] See Figure 6As shown, according to some embodiments of the present invention, the limiting assembly 163 includes a connecting ring 164, a push rod 165, a first limiting rod 166, and a second limiting rod 167. The connecting ring 164 is sleeved on the connecting rod 162 and is slidable along the connecting rod 162. The other end of the connecting rope 170 is connected to the connecting ring 164 to adjust the position of the connecting ring 164 on the connecting rod 162. One end of the push rod 165 is connected to the connecting ring 164, and the push rod 165 moves along the axial direction of the connecting rod 162. Thus, the position of the push rod 165 on the connecting rod 162 can be adjusted by the connecting rope 170 and the connecting ring 164. The push rod 165 is attached to the outer periphery of the connecting rod 162. In some embodiments, the outer periphery of the connecting rod 162 is provided with a groove extending along its axial direction, and the push rod 165 is disposed in the groove to limit the movement path of the push rod 165 and prevent the push rod 165 from rotating along the outer periphery of the connecting rod 162.

[0109] One end of the first limiting rod 166 is hinged to the other end of the push rod 165, one end of the second limiting rod 167 is hinged to the other end of the first limiting rod 166, and the other end of the second limiting rod 167 is hinged to the end of the connecting rod 162. When the push rod 165 moves along the connecting rod 162, the first limiting rod 166 and the second limiting rod 167 rotate. When the limiting assembly 163 is in the extended state, the push rod 165 drives the first limiting rod 166 and the second limiting rod 167 to abut against the outer peripheral wall of the connecting rod 162; when the limiting assembly 163 is in the limited state, the push rod 165 drives the first limiting rod 166 and the second limiting rod 167 to form a raised structure. Figure 2 As shown, when the connecting rod 162 passes through the adapter 102, the adjusting limiting component 163 is in the limiting state. The first limiting rod 166 is perpendicular to the connecting rod 162. The first limiting rod 166, the second limiting rod 167 and the connecting rod 162 form a triangular structure to limit the position of the adapter 102. The adapter 102 is clamped between the first limiting rod 166 and the second fixing post 161.

[0110] See Figure 6 As shown, in some embodiments, the limiting assembly 163 further includes a reset member 168, which is sleeved on the connecting rod 162 and sandwiched between the second fixing post 161 and the connecting ring 164. The reset member 168 is adapted to drive the connecting ring 164 to move toward the other end of the connecting rod 162, so that the first limiting rod 166 and the second limiting rod 167 form a raised structure. The connecting rope 170 can drive the connecting ring 164 to move toward the second fixing post 161, so that the first limiting rod 166 and the second limiting rod 167 fit against the outer periphery of the connecting rod 162, allowing the connecting rod 162 to disengage from the adapter 102. The reset member 168 can be a spring.

[0111] See Figure 6As shown, according to some embodiments of the present invention, there are multiple push rods 165, first limiting rods 166, and second limiting rods 167. These multiple push rods 165, first limiting rods 166, and second limiting rods 167 are distributed at intervals along the circumference of the connecting rod 162, and are connected one-to-one. This allows for fixation of the connection between the connecting rod 162 and the adapter 102 from multiple directions, improving the stability of the adapter 102.

[0112] During the process of fixing the adapter 102, the second sleeve 132 is adjusted to slide relative to the first sleeve 131, so that the position of the movable component 160 corresponds to the connection through hole on the adapter 102. Pressing the connecting ring 164 compresses the reset member 168 and generates a restoring force. At this time, the first limiting rod 166 and the second limiting rod 167 are both in contact with the outer circumferential surface of the connecting rod 162, allowing the connecting rod 162 to pass smoothly through the connection through hole on the adapter 102, connecting the adapter 102 to the movable component. Then, the connecting ring 164 is released. Driven by the reset member 168, the connecting ring 164 moves towards the other end of the connecting rod 162. The connecting ring 164 drives the push rod 165 to push the first limiting rod 166 and the second limiting rod 167 to rotate, so that the first limiting rod 166 and the second limiting rod 167 form a raised structure, thereby fixing the position of the adapter 102.

[0113] After the adapter 102 is fixed, push the intermediate rod 181 toward the winding drum 152. The locking member 180 is in the locked position. The first engagement part 153 and the second engagement part 185 engage, and the third engagement part 182 engages with the fourth engagement part 157 to prevent the intermediate rod 181 and the winding drum 152 from rotating. This prevents the connecting rope 170 from winding up and the connecting ring 164 from moving toward the second fixed post 161, which would cause the adapter 102 and the movable component 160 to detach or become unstable, thus affecting the testing process.

[0114] When the adapter card 102 needs to be removed, pull the middle rod 181 to move away from the winding drum 152. The locking member 180 is in the unlocked position. The first engagement part 153 disengages from the second engagement part 185, and the third engagement part 182 disengages from the fourth engagement part 157. Both the rotating part 184 and the winding drum 152 can be driven. The connecting rope 170 is wound up and the connecting ring 164 is pulled to move towards the second fixed post 161. The first limiting rod 166 and the second limiting rod 167 move to fit against the outer peripheral surface of the connecting rod 162. The connecting rod 162 can disengage from the connecting through hole on the adapter card 102, thereby allowing the adapter card 102 to be removed.

[0115] See Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the test fixture 100 further includes a reinforcing component 190, which can be connected to the adapter card 102 for further securing the adapter card 102 and preventing the adapter card 102 from shaking during testing. Specifically, see... Figure 1 As shown, the adapter card 102 is provided with a reinforcement hole 103, and the reinforcement component 190 is fixedly connected to the adapter card 102 through the reinforcement hole 103.

[0116] Here, the number of reinforcement holes 103 is not specifically limited. For example, in some examples, there can be multiple reinforcement holes 103 spaced apart. On the one hand, the reinforcement component 190 can be connected to one or more of the reinforcement holes 103, thereby improving the stability and flexibility of the connection between the reinforcement component 190 and the adapter card 102. On the other hand, when the adapter card 102 model is different, the position of the reinforcement holes 103 will change. By setting multiple reinforcement holes 103, the reinforcement component 190 can be better matched, so that any model of adapter card 102 can have a corresponding reinforcement hole 103 to connect with the reinforcement component 190, thereby facilitating the connection between the reinforcement component 190 and the adapter card 102.

[0117] Furthermore, it should be noted that the shape of the reinforcing hole 103 is not specifically limited here. For example, in some embodiments, the reinforcing hole 103 can be a round hole to facilitate drilling on the adapter card 102; of course, the reinforcing hole 103 can also be a square hole or an elliptical hole, etc. Among them, a square hole is a common shape, which can provide good support and rigidity, and is suitable for situations that need to withstand greater forces and pressures; an elliptical hole has a greater curvature than a square hole, which can provide better flexibility and extensibility in the connection structure 130. An elliptical hole can also provide different rigidity and strength in different directions, which is suitable for some specific assembly needs.

[0118] See Figure 2 and Figure 3As shown, according to some embodiments of the present invention, the reinforcement component 190 includes a reinforcement rod 191 and a snap-fit ​​rod 193. The reinforcement rod 191 is connected to the test platform and has a straight rod-like structure. The reinforcement rod 191 is attached to the adapter clip 102. The reinforcement rod 191 has an adjustment slot 192, and the snap-fit ​​rod 193 passes through the adjustment slot 192 and the reinforcement hole 103 in sequence. It should be noted that the snap-fit ​​rod 193 can slide within the adjustment slot 192 to adjust its position relative to the fixed rod. Simultaneously, while adjusting its position, the snap-fit ​​rod 193 can move to a position corresponding to the reinforcement hole 103, allowing it to pass through the adjustment slot 192 and the reinforcement hole 103 in sequence. Thus, the fixed rod can be fixed to the adapter clip 102 using the snap-fit ​​rod 193. To improve the connection stability between the fixing rod and the adapter 102, the clip rod 193 is connected to both the reinforcing rod 191 and the adapter 102.

[0119] To further improve the connection stability between the fixing rod and the adapter 102, see Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, one end of the snap-fit ​​rod 193 is provided with a first fixing member 194, which is fixedly connected to the reinforcing rod 191. The other end of the snap-fit ​​rod 193 is provided with a second fixing member 195, which is snapped into the adapter 102. In this way, both ends of the snap-fit ​​rod 193 can be fixed by the corresponding first fixing member 194 and second fixing member 195, thereby the reinforcing rod 191 can be fixed to the adapter 102 by using the snap-fit ​​rod 193.

[0120] Furthermore, the first fastener 194 is a magnetic component, and the magnetic connection can achieve connection and fixation through magnetic attraction and attraction. Additionally, in some embodiments, the second fastener 195 is an elastically deformable component. For example, the second fastener 195 is an elastically deformable component capable of deformation, utilizing its elastic deformation to provide a fixing effect. When selecting and using an elastically deformable component, the characteristics of the elastic material, such as material hardness, durability, and elastic recovery performance, need to be considered. Furthermore, the size and shape design of the elastically deformable component can match the shape of the reinforcing hole 103 to ensure the reliability and stability of the fixation.

[0121] According to some embodiments of the present invention, such as Figure 1 As shown, the connecting plate 120 has a strip-shaped adjustment hole 121. The connecting plate 120 is connected to the PCIe card 104 via a support platform 122. It can be understood that the support platform 122 can be used to support the PCIe card 104. In some examples, the support platform 122 can be an L-shaped plate, which facilitates both supporting the PCIe card 104 and connecting the support platform 122 to the connecting plate 120. Specifically, as... Figure 7 As shown, the connecting plate 120 has a fixed cylinder 123 on the side opposite to the PCIE card 104. The fixed cylinder 123 has a movable rod 126 inside. The movable rod 126 is movably inserted into the fixed cylinder 123. The movable rod 126 is fixedly connected to the support platform 122. The movable rod 126 is adapted to move along the strip-shaped adjustment hole 121 to drive the support platform 122 to move.

[0122] Further, see Figure 7 As shown, the fixed cylinder 123 has a first positioning hole, and the movable rod 126 has a second positioning hole 127. The test fixture 100 also includes a moving rod 129, which is adapted to pass through the first positioning hole and the second positioning hole 127 in sequence to fix the fixed cylinder 123 and the movable rod 126. In this way, the fixed cylinder 123 and the movable rod 126 can be positioned using the moving rod 129.

[0123] See Figure 7 As shown, according to some embodiments of the present invention, the fixed cylinder 123 is provided with a limiting perforation 125, and the movable rod 126 is provided with a fixing tooth 128. The fixing tooth 128 is rotatably disposed on the movable rod 126. When the movable rod 126 moves relative to the fixed cylinder 123, the fixing tooth 128 is adapted to extend through the limiting perforation 125. In this way, the fixing tooth 128 can be used to coarsely position the movable rod 126.

[0124] Specifically, since the fixed locking tooth 128 is rotatably mounted on the movable rod 126, when the movable rod 126 moves relative to the fixed cylinder 123, the fixed locking tooth 128 can move with the movable rod 126. When the fixed locking tooth 128 moves to the limiting cutout 125, the fixed locking tooth 128 rotates relative to the movable rod 126 and can pass through the limiting cutout 125, thereby positioning the movable rod 126. When the fixed locking tooth 128 passes through the limiting cutout 125, it can fix the movable rod 126 at the corresponding position on the fixed cylinder 123. At this time, a movable rod 129 can be taken and passed through the first positioning hole and the second positioning hole 127 in sequence, further fixing the fixed cylinder 123 and the movable rod 126. This improves the relative stability between the fixed cylinder 123 and the movable rod 126.

[0125] See Figure 7As shown, according to some embodiments of the present invention, the test fixture 100 further includes a height adjustment component 196. Part of the height adjustment component 196 is connected to the connecting plate 120, and another part is connected to the test platform. The height adjustment component 196 serves to support the connecting plate 120 and adjusts the vertical distance between the connecting plate 120 and the test platform. The height adjustment component 196 includes a mounting base 197 and a limiting post 198. The mounting base 197 is sleeved on the limiting post 198 and is movable along the limiting post 198. The mounting base 197 is connected to the connecting plate 120, and the limiting post 198 is connected to the test platform. By driving the mounting base 197 to move relative to the limiting post 198, the connecting plate 120 is moved to adjust the distance between the connecting plate 120 and the test platform. In some embodiments, the limiting post 198 can be a threaded rod, and the mounting base 197 has a threaded hole. By driving the limiting post 198 to rotate, the mounting base 197 is driven to move.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
