Description

Technical Field

[0001] The present application relates to the technical field of auxiliary plugging and unplugging, and in particular to a plugging and unplugging tool. Background Art

[0002] Gold fingers are a key part for data transmission and communication between pluggable hardware (such as memory sticks) and the motherboard. Gold fingers are very fragile parts. If they are damaged or contaminated, they are prone to oxidation and form an oxide layer, which hinders the transmission of electrical signals and affects the normal operation of server equipment. In related technologies, two plug-ins are usually used to ensure the connection stability between the memory stick and the motherboard slot. Summary of the invention

[0003] The present application provides a plugging and unplugging tool to at least solve the problem of low plugging and unplugging efficiency in the related art.

[0004] The present application provides a plug-in tooling jig for installing pluggable hardware into a slot, and the plug-in tooling jig includes:

[0005] A shell having openings at both ends, the shell being arranged above the slot, and the inner cavity of the shell being opposite to the slot;

[0006] A plug-in assembly, the plug-in assembly is movably connected in the housing, and the plug-in assembly includes a contact portion, the contact portion is used to contact the gold finger of the pluggable hardware; wherein the plug-in assembly can move along a first direction so that the contact portion encloses a size-adjustable accommodation area in the housing, and the accommodation area is used for the pluggable hardware to pass through;

[0007] The pluggable hardware enters the housing through the opening facing away from the slot, and the contact portion contacts the pluggable hardware, so that the accommodating area undergoes adaptive changes, and the pluggable hardware then penetrates the accommodating area and is inserted into the slot.

[0008] The present application additionally provides a plug-in tooling jig, which can cooperate with the slot. For example, the jig can be set above the slot and set corresponding to the slot. The pluggable hardware enters the shell through the opening away from the slot, and during the movement of the shell toward the slot, the contact portion contacts and rubs against the gold finger of the pluggable hardware to remove the oxide layer of the gold finger of the pluggable hardware. After that, the pluggable hardware continues to move toward the slot until it is inserted into the slot. In this way, the gold fingers of the pluggable hardware can be cleaned, and there is no need for secondary plugging and unplugging, which simplifies the operation steps of the pluggable hardware and improves the plug-in efficiency of the pluggable hardware.

[0009] In addition, the contact part can move in the first direction so that the contact part encloses a size-adjustable accommodating area inside the housing, enabling pluggable hardware of different sizes to pass through the accommodating area smoothly, thus expanding the application scope of the plugging and unplugging tooling fixture.

[0024] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The gold finger is a key part for data transmission and communication between pluggable hardware (such as memory modules, CPUs, SSD hard drives, or mechanical hard drives) and the motherboard. Among them, the thicker the gold layer of the gold finger, the higher the durability of the device and the lower the failure rate.

[0026] However, the gold finger is a very fragile part and is easily damaged or contaminated. During the transportation of electronic devices with gold fingers, due to the influence of humidity in the environment, the gold finger part is prone to oxidation, forming an oxide layer, which hinders the transmission of electrical signals and affects the normal operation of server equipment. For example, after the memory module is inserted into the memory slot, anomalies such as the memory not being detected may occur. In many cases, we may not be able to detect potential problems just by observing the gold finger with the naked eye, so some failures may occur. Failures of the gold finger may lead to serious consequences such as the server host being unable to start, crashing without a pattern, a blue screen, or being unable to enter the system.

[0027] Regarding the problem that the oxide layer on the surface of the gold finger causes poor contact between the pluggable hardware and the motherboard, in related technologies, usually two consecutive plugging and unplugging operations can be performed. That is, during the first insertion, the oxide layer on the surface of the gold finger can be rubbed to remove the oxide layer; then, the pluggable hardware needs to be pulled out again and inserted at the same position again to ensure the stability of the contact between the gold finger and the slot contacts by repeating the plugging and unplugging.

[0028] However, the above plugging and unplugging method requires employees to operate twice, increasing the working hours, and thus resulting in the defect of low plugging and unplugging efficiency.

[0029] Therefore, the embodiment of the present application provides a plugging and unplugging tooling fixture for installing the pluggable hardware 400 (please refer to Figure 2 shown) into the slot. It should be noted that the slot can be either a component on the motherboard for electrical connection and data transmission with the pluggable hardware, or a component with similar functions on other electrical components. The embodiment of the present application does not limit this.

[0030] Combined with Figure 1 、 Figure 4 and Figure 5As shown, the plug-and-play tooling fixture includes a housing 100. The housing 100 has openings at both ends, making the inner cavity of the housing 100 a through chamber. This design allows the pluggable hardware 400 to enter from one end of the housing 100 and finally dock with the slot from the other end of the housing 100, facilitating the housing 100 to allow the pluggable hardware 400 to pass through. In this embodiment, the material of the housing 100 includes but is not limited to bakelite material (phenolic resin). The bakelite material (phenolic resin) has excellent insulation properties. When the pluggable hardware 400 passes through the inner cavity of the housing 100, the bakelite material can effectively prevent the conduction of current, avoiding electric shock to the operator due to accidental leakage and other situations, and also preventing the current from interfering with the pluggable hardware 400 and surrounding electronic components, ensuring the electrical safety and stability of the pluggable hardware 400 during the plugging and unplugging operations. In addition, the bakelite material has appropriate hardness and strength, which can provide sufficient support and protection for the pluggable hardware 400. During the plugging and unplugging process, the housing 100 needs to bear a certain amount of external force. The hardness and strength of the bakelite material can ensure that the housing 100 does not deform, thereby ensuring that the pluggable hardware 400 will not be damaged due to extrusion or collision during the passing process.

[0031] In the embodiment of the present application, the housing 100 is used to be disposed above the slot, and the inner cavity of the housing 100 faces the slot 500. In other words, in the third direction (perpendicular to the direction of the slot 500), that is Figure 2 in the Z direction, the inner cavity of the housing 100 is disposed opposite to the slot 500, or rather, the inner cavity of the housing 100 is located directly above the slot 500. This can ensure that after the pluggable hardware 400 enters from one end opening of the housing 100, passes through the inner cavity of the housing 100, and then moves precisely in the direction of the slot 500 and finally is successfully inserted into the slot 500, realizing the effective connection between the pluggable hardware 400 and the slot 500.

[0032] It should be noted that the shape of the inner cavity of the housing 100 can match the shape of the pluggable hardware 400. Exemplarily, the pluggable hardware 400 is a sheet-like structure, and correspondingly, the inner cavity of the housing 100 is also a sheet-like structure. In addition, the housing 100 is disposed above the slot. It can be understood that the housing 100 and the slot can be directly connected or indirectly connected. Exemplarily, the housing 100 is directly detachably connected to the component forming the slot. When the plug-and-play tooling fixture needs to be used, the housing 100 can be connected to the component forming the slot. After the installation of the pluggable hardware 400 is completed, the housing 100 can be disassembled to facilitate its application to the installation process of the next pluggable hardware 400.

[0033] In some examples, such as Figure 1As shown, the housing 100 includes two first side plates and two second side plates. The two first side plates are arranged at intervals in the first direction, and the two second side plates are arranged in the second direction and are respectively connected to the two first side plates, so that the housing 100 forms a rectangular frame. It should be noted that the housing 100 can be integrally formed by an injection molding process, and there are no weak links caused by splicing or assembly. When inserting and removing the pluggable hardware 400, each part of the housing 100 can evenly bear the external force, avoiding structural damage caused by local stress concentration and improving the service life of the housing 100.

[0034] It should be understood that the setting of the first direction needs to be based on the shape of the pluggable hardware 400 and the relative position of the contact part with the pluggable hardware 400. In the following embodiments, it is assumed that the pluggable hardware 400 is rectangular and the contact part is located on one side of the large surface of the pluggable hardware. Accordingly, the first direction is the vertical direction between the two large surfaces of the pluggable hardware, that is Figure 1 the X direction in Figure 1 the Y direction in

[0035] The plugging and unplugging tooling fixture further includes a plugging and unplugging component 200, and the plugging and unplugging component 200 is movably connected in the housing 100. The plugging and unplugging component 200 includes a contact part, and the contact part is used to contact the gold fingers of the pluggable hardware 400. During the subsequent movement of the pluggable hardware 400 in the housing 100, the contact part can contact the pluggable hardware 400 and rub the gold fingers of the pluggable hardware 400 to remove the oxide layer on the surface of the gold fingers of the pluggable hardware 400, improving the cleanliness of the gold fingers of the pluggable hardware 400.

[0036] Wherein, the plugging and unplugging component 200 can move along the first direction, so that the contact part encloses an accommodation area with adjustable size in the housing 100, and the accommodation area is used for the pluggable hardware 400 to pass through.

[0037] Combined with Figure 1 and Figure 2 As shown, the pluggable hardware 400 enters the housing 100 through the opening of the housing 100 facing away from the slot, and the contact part contacts the pluggable hardware 400, so that the accommodation area changes adaptively, and then the pluggable hardware 400 passes through the accommodation area and is inserted into the slot. It should be noted that the opening facing away from the slot can be understood as the top opening of the housing 100. Exemplarily, along the direction perpendicular to the slot, the opening of the housing 100 includes a first opening and a second opening arranged opposite to each other, and the second opening is adjacent to the slot so that the second opening is the bottom opening and the first opening is the top opening.

[0038] The pluggable hardware 400 can enter the housing 100 through the first opening and move toward the slot until the pluggable hardware 400 passes through the accommodating area and is inserted into the slot. During the movement, the contact portion contacts and rubs against the gold fingers of the pluggable hardware 400 to remove the oxide layer of the gold fingers of the pluggable hardware, thereby improving the cleanliness of the gold fingers. Afterwards, the pluggable hardware 400 continues to move toward the slot until it is inserted into the slot. In this way, the gold fingers of the pluggable hardware 400 can be cleaned without the need for secondary plugging and unplugging, which simplifies the operating steps of the pluggable hardware 400 and thereby improves the plugging and unplugging efficiency of the pluggable hardware 400. In addition, after completing the cleaning process, the pluggable hardware 400 can be directly put into use, thereby reducing or even avoiding the risk of secondary oxidation.

[0039] Since the plug-in assembly 200 can move along the first direction, after the contact portion contacts the pluggable hardware, a force along the first direction and toward the inner wall of the shell 100 can be applied to the plug-in assembly 200. Driven by the force, the contact portion moves toward the inner wall of the shell 100, so that the accommodating area changes adaptively. In this way, pluggable hardware 400 of different sizes can be inserted into the slot by the plug-in jig, thereby improving the application range of the plug-in jig.

[0040] It should be noted that the plug assembly 200 can be an integral component. For example, the plug assembly 200 can be an elastic strip structure made of elastic material. The plug assembly 200 can be set on any inner wall of the shell 100 in the first direction. In this way, the part of the plug assembly 200 close to the center of the shell 100 constitutes the contact part.

[0041] The plug assembly 200 may also be a split structure, and the movement of the contact portion in the first direction may be achieved by a hinge or an elastic arm. Figure 1 and Figure 3 As shown, the plug assembly 200 includes an elastic member 210 and a contact member 220 connected to the elastic member 210. The end of the elastic member 210 facing away from the contact member 220 is connected to the inner wall of the housing 100. In other words, one end of the elastic member 210 is connected to the inner wall of the housing 100, and the other end is connected to the contact member 220. Among them, the end of the contact member 220 facing away from the elastic member 210 constitutes a contact portion. It should be noted that the connection mentioned in this embodiment can be a direct connection or an indirect connection.

[0042] Among them, the elastic member 210 can be a spring, and the connections between the elastic member 210 and the inner wall of the housing 100 and the contact member 220 can both be detachable connections. In this way, elastic members 210 with different elastic forces can be selected according to the model of the pluggable hardware 400, improving the compatibility of the plugging and unplugging tooling fixture. For example, for some relatively thin pluggable hardware (such as memory modules), low-elasticity springs can be selected to avoid excessive pressure on the contact member 220 causing deformation of the pluggable hardware 400. Another example is that for some relatively thick pluggable hardware (such as expansion cards), high-elasticity springs can be selected to ensure that the contact member 220 can be in close contact with the gold fingers of the pluggable hardware 400, effectively removing the oxide layer. In addition, if the spring becomes fatigued or damaged after long-term use, it can be replaced separately without scrapping the entire plugging and unplugging assembly 200, reducing the maintenance cost.

[0043] The contact member 220 is used to simulate the pins in the slot 500. Therefore, the contact member 220 has high hardness, good electrical conductivity and heat resistance. Exemplarily, the material of the contact member 220 includes but is not limited to tungsten carbide.

[0044] The elastic member 210 is used to drive the contact member 220 to move in the first direction. When the pluggable hardware 400 enters the housing 100 through the first opening and contacts the end of the contact member 220 away from the elastic member 210, at this time, the pluggable hardware 400 can apply a force in the first direction and towards the inner wall of the housing 100 to the elastic member 210, and this force can drive the contact member 220 to move towards the inner wall of the housing 100 to increase the size of the accommodating area. When the pluggable hardware 400 moves out of the housing 100, it can also rely on the elastic restoring force of the elastic member 210 to drive the contact member 220 to move towards the center of the housing 100 so that the contact member 220 returns to its initial position. It should be understood that during the process of the contact member 220 moving towards the inner wall of the housing 100, due to the maintaining function of the elastic member 210, the contact member 220 can always be in contact with the pluggable hardware 400.

[0045] In this embodiment, the contact member 220 is replicated one-to-one with the probe in the slot, and then cooperates with the elastic member 210 with adjustable elasticity, so as to simulate the force exerted by the probe in the slot on the pluggable hardware 400. When the pluggable hardware 400 enters the housing 100 through the first opening, the acting force exerted by the elastic member 210 on the contact member 220 is equivalent to the acting force exerted by the probe of the slot on the pluggable hardware 400. Therefore, the pluggable hardware 400 passing through this jig is equivalent to having its gold finger part cleaned once; afterwards, the pluggable hardware 400 can continue to move towards the slot 500 until it is inserted into the slot 500 and can be used normally. In this way, not only can the gold fingers of the pluggable hardware 400 be cleaned, but also secondary plugging is not required, which simplifies the operation steps of the pluggable hardware 400, thereby improving the plugging and unplugging efficiency of the pluggable hardware 400. In addition, after the pluggable hardware 400 completes the cleaning process, it is directly put into use, reducing or even avoiding the risk of secondary oxidation.

[0046] It should be noted that during the use process, the elasticity of the elastic member 210 can be adjusted at any time, and spot checks can be carried out regularly to ensure that the elasticity of the elastic member 210 is highly consistent with the acting force of the pins of the slot 500, so as to avoid excessive elasticity of the elastic member 210 from damaging the gold fingers of the pluggable hardware 400 and reducing the service life of the pluggable hardware 400, and to avoid too small elasticity of the elastic member 210 from being insufficient to clean the gold fingers of the pluggable hardware 400, ensuring that the oxides on the surface of the gold fingers are completely removed.

[0047] It should also be noted that the elastic member 210 and the contact member 220 can be directly connected. In some embodiments, the elastic member 210 and the contact member 220 are connected together to form an integral component, and the number of such integral components can be multiple. The multiple integral components are arranged at intervals along the second direction and are connected to the housing 100.

[0048] In other embodiments, the elastic member 210 and the contact member 220 can also be indirectly connected. As Figure 1 and Figure 3 shown, the plugging and unplugging assembly 200 further includes a connecting member 230 extending along the second direction; the second direction intersects the first direction, and exemplarily, the second direction is perpendicular to the first direction. Wherein, the connecting member 230 can be a strip-shaped body extending along the second direction, and there is a gap between the end of the connecting member 230 in the second direction and the corresponding inner wall, so as to ensure that the connecting member 230 can move in the first direction. As for the size of the gap between the end of the connecting member 230 in the second direction and the corresponding inner wall, it can be freely set according to the actual situation, and this embodiment will not elaborate on it here.

[0049] One end of the elastic member 210 is detachably connected to the housing 100, and the other end of the elastic member 210 is detachably connected to the connecting member 230; the contact member 220 is disposed on the connecting member 230 and is located on a side of the connecting member 230 away from the elastic member 210.

[0050] In this embodiment, the connection between the elastic member 210 and the contact member 220 is achieved through the connecting member 230. When the contact member 220 is worn or needs to be upgraded (such as replacing with a material having higher wear resistance), it can be replaced only by disassembling the connecting member 230 without adjusting the elastic member 210, which simplifies the maintenance process. In addition, as a rigid or semi-rigid structure, the connecting member 230 can uniformly transmit the elastic force of the elastic member 210 to the contact member 220, avoiding the problem of uneven local pressure caused by directly connecting the elastic member to the contact member 220, and ensuring the consistent overall cleaning effect of the gold fingers.

[0051] It should be noted that the number of the elastic members 210 in the embodiment of the present application can be multiple. The multiple elastic members 210 are arranged at intervals in the second direction (usually the length direction of the pluggable hardware 400) between the connecting member 230 and the inner wall of the housing 100. By providing the multiple elastic members 210, the connecting member 230 and the contact member 220 can apply more uniform pressure to the gold fingers of the pluggable hardware 400, avoiding the problem of excessive or too small local pressure. In addition, by increasing or decreasing the number of the elastic members 210, the gold fingers of different lengths can be flexibly adapted to ensure that the effective area of the gold fingers is fully covered by the contact member 220.

[0052] Please continue to refer to Figure 1 , the number of the contact members 220 is multiple, and the multiple contact members 220 are arranged at intervals in the second direction on the connecting member 230; the multiple contact members 220 are arranged in one-to-one correspondence with the multiple gold fingers of the pluggable hardware. This precise matching design can ensure that each contact member 220 can achieve good contact with the corresponding gold finger, effectively clean each gold finger, so as to ensure the cleanliness of each gold finger and improve the connection stability between the gold finger and the pin.

[0053] It should be noted that the number of contacts 220 and the number of elastic members 210 may or may not correspond. In some embodiments, the number of elastic members 210 is greater than the number of contacts 220. In addition, the contacts 220 and the connecting members 230 may be detachably connected, so that the number of contacts 220 can be freely set according to actual needs, enabling the number of contacts 220 to match the number of gold fingers of the pluggable hardware 400. For example, for some high-performance graphics cards with a large number of gold fingers, more contacts 220 are required to ensure stable electrical connection; while for some low-power memory cards with relatively fewer gold fingers, the number of contacts 220 can be reduced at this time. This precise matching ensures good contact between the contacts 220 and the gold fingers, improving the cleaning accuracy.

[0054] In some embodiments, along the first direction, the housing 100 has a first side wall and a second side wall that are oppositely arranged; Figure 1 Taking the shown orientation as an example, the first side wall is the left side wall of the housing 100, and the second side wall is the right side wall of the housing 100.

[0055] The plugging and unplugging assembly 200 includes a first plugging and unplugging assembly 240 and a second plugging and unplugging assembly 250. The first plugging and unplugging assembly 240 is disposed on the first side wall, and the second plugging and unplugging assembly 250 is disposed on the second side wall. A receiving area is formed between the first plugging and unplugging assembly 240 and the second plugging and unplugging assembly 250 for the pluggable hardware 400 to be inserted.

[0056] With such a setting, in the first direction, the first plugging and unplugging assembly 240 and the second plugging and unplugging assembly 250 are respectively disposed on the left and right sides of the pluggable hardware 400. The first plugging and unplugging assembly 240 cleans the surface corresponding to its gold fingers, and the second plugging and unplugging assembly 250 cleans the surface corresponding to its gold fingers, which can avoid poor cleaning effect on one side and further reduce the risk of residual oxide layer.

[0057] In addition, the first plugging and unplugging assembly 240 and the second plugging and unplugging assembly 250 apply balanced forces to the opposite sides of the pluggable hardware 400, avoiding the bending of the gold fingers of the pluggable hardware 400 caused by excessive pressure on one side and improving the service life of the pluggable hardware 400.

[0058] In some embodiments, the range of the elastic restoring force provided by the elastic member 210 when the pluggable hardware 400 is inserted is A, and A satisfies: 200g ≤ A ≤ 350g. Exemplarily, the elastic restoring force provided by the elastic member 210 when the pluggable hardware 400 is inserted is 200g, 250g, 300g, 350g, and the range formed by any two values. This embodiment will not be further limited here.

[0059] The types of the pluggable hardware 400 are different, or the models of the pluggable hardware 400 in the same type are different, so the insertion forces when inserting into the housing 100 are different. Therefore, the elastic restoring forces provided by the elastic member 210 when the pluggable hardware 400 is inserted are also different.

[0060] In the following embodiments, the pluggable hardware 400 will be described by taking a memory module as an example. The common models of memory modules usually include DDR4 memory modules and DDR5 memory modules. The thicknesses of DDR4 memory modules and DDR5 memory modules are different, so the insertion forces used to insert into the housing 100 are also different. For example, the insertion force for inserting a DDR4 memory module into the housing 100 is usually about 250 g. Another example, the insertion force for inserting a DDR5 memory module into the housing 100 is usually about 300 g.

[0061] In this embodiment, by limiting the elastic restoring force that the elastic member 210 can provide when the pluggable hardware 400 is inserted, the elastic restoring force is greater than or equal to 200 g and less than or equal to 350 g. In this way, the elastic restoring force range (200 g~350 g) of the elastic member 210 can cover the plugging and unplugging requirements of mainstream memory modules, ensuring smooth insertion and providing sufficient contact pressure.

[0062] At the same time, it can also prevent the elastic restoring force provided by the elastic member 210 when the pluggable hardware 400 is inserted from being too small, ensuring sufficient contact pressure to scrape the oxide layer on the surface of the gold fingers. It can also prevent the elastic restoring force from being too large to prevent damage caused by excessive pressure between the gold fingers and the contact member 220.

[0063] As Figure 3 shown, in some embodiments, the plugging and unplugging assembly further includes a cleaning member 260, and the cleaning member 260 is arranged in the housing 100. It should be noted that the cleaning member 260 can be directly arranged on the inner wall of the housing 100, or can be arranged on the connecting member 230 and on the same side as the contact member 220.

[0064] The opening includes a first opening and a second opening which are oppositely arranged. The second opening is adjacent to the pluggable hardware 400. That is, the first opening is the top opening and the second opening is the bottom opening. The cleaning member 260 is arranged on the connecting member 230, and along the direction from the first opening to the second opening, the cleaning member 260 and the contact member 220 are stacked in sequence. In other words, the cleaning member 260 is adjacent to the first opening of the housing 100 so that the cleaning member 260 is located above the contact member 220. It should be noted that in the third direction, the vertical distance between the cleaning member 260 and the contact member 220 can be freely set according to actual needs. Among them, the material of the cleaning member 260 can be rubber or alcohol cotton.

[0065] During use, the pluggable hardware 400 enters the housing 100 through the first opening. The gold fingers of the pluggable hardware 400 first touch the soft cleaning member 260, and the cleaning member 260 pre-cleans the gold fingers of the pluggable hardware 400 to remove some dirt or impurities on the surface of the gold fingers. After that, the pluggable hardware 400 continues to move towards the second opening and touches the harder contact member 220. The contact member 220 and the gold fingers of the pluggable hardware 400 rub against each other to remove the oxide layer on the surface of the gold fingers.

[0066] With such a setting, the cleaning member 260 and the contact member 220 can provide double cleaning guarantees. For example, the soft characteristic of the cleaning member 260 can avoid scratching the surface of the gold fingers, and at the same time effectively adsorb or wipe off loose dirt; the contact member 220 has a greater hardness and can effectively remove the oxide layer through the frictional action. This cleaning method with a clear division of labor greatly improves the cleaning efficiency and quality.

[0067] In some embodiments, the plugging and unplugging tooling fixture further includes a pressing component 300 for installing the pluggable hardware 400. Or rather, the pressing component 300 is a carrier for the pluggable hardware 400, facilitating the installation of the pluggable hardware 400 on the pressing component 300 and applying a force perpendicular to the housing 100 (or the slot) to the pressing component 300 and the pluggable hardware 400, ensuring that the pluggable hardware 400 can pass through the accommodating area of the housing 100 and be inserted into the slot.

[0068] As Figure 2 shown, the pressing component 300 at least includes a first pressing member 310, and the first pressing member 310 is at least disposed on one side of the pluggable hardware 400 in the second direction. In one example, the first pressing member 310 is disposed on one side of the pluggable hardware 400 in the second direction. In another example, the first pressing member 310 is disposed on both sides of the pluggable hardware 400 in the second direction. Among them, the second direction can be the length direction of the pluggable hardware 400.

[0069] The length of the first pressing member 310 in the third direction is less than the length of the pluggable hardware 400 in the third direction. In other words, the end of the first pressing member 310 facing the slot 500 is higher than the end of the pluggable hardware 400 facing the slot 500, so that the first pressing member 310 does not block the gold finger area of the pluggable hardware 400.

[0070] In this embodiment, the third direction, the second direction, and the first direction intersect pairwise. Among them, the third direction is the direction perpendicular to the slot, that is, the height direction of the pluggable hardware 400, that is Figure 2 the Z direction in

[0071] As Figure 4 and Figure 5As shown, along the third direction and in the direction pointing to the slot, the width of the first pressing member 310 in the first direction shows a decreasing trend. It should be understood that in this embodiment, the decreasing trend can be understood as a generally decreasing trend. The width of the part of the first pressing member 310 facing the slot 500 in the first direction is smaller than the width of the part away from the slot 500 in the first direction. It can also be understood that the width of the first pressing member 310 in the first direction shows a gradually decreasing trend.

[0072] Taking the pluggable hardware 400 as a memory module as an example, the following describes the specific operation steps of inserting the pluggable hardware 400 into the slot via the plugging tooling fixture. The steps include:

[0073] First, open the sea terminals at both ends of the memory module and install the memory module into the pressing assembly 300. It should be noted that the sea terminals are inherent components of the memory module and are related technologies, so this embodiment will not elaborate on them here.

[0074] After that, hold the pressing assembly 300 so that the memory module enters the housing 100 through the first opening. The gold finger position of the memory module first contacts the cleaning member 260 and the contact member 220. At this time, the area of the memory module above the gold finger has not yet contacted the cleaning member 260 and the contact member 220.

[0075] After that, as the memory module continues to move towards the slot, since the width of the first pressing member 310 in the first direction is relatively small in the direction close to the slot, it does not affect the cleaning member 260 and the contact member 220 from cleaning the memory module.

[0076] When the gold finger of the memory module moves to the lower part of the contact member 220, please refer to Figure 4 , the first pressing member 310 starts to contact the vertex position of the contact member 220. The first pressing member 310 applies a force towards the housing 100 and along the first direction to the contact member 220. This force will make the elastic member 210 in a compressed state, thereby increasing the size of the accommodation area in the first direction (please refer to Figure 5 ), so as to reserve space for the movement of the memory module.

[0077] After that, the memory module continues to move along the third direction and towards the slot. In this way, the area of the pluggable hardware 400 other than the gold fingers will not contact the contact member 220, which can prevent the components above the gold fingers of the memory module from being scratched, thus ensuring that the memory module can be smoothly and completely inserted into the slot.

[0078] It is not until the hippocampus heads at both ends of the memory module are completely snapped into the concave holes at both ends of the memory that the memory module is truly inserted into the memory slot. After that, the pressing component 300 can be lifted in the third direction and away from the slot 500. Since the force of the first pressing member 310 on the contact member 220 always exists, at this time, the housing 100 will be lifted together with the first pressing member 310, and only the memory module is inserted into the slot.

[0079] After the housing 100 and the pressing component 300 are lifted, the pressing component 300 can be manually withdrawn from the housing 100. When withdrawn, the elastic member 210 located in the housing 100 will slowly return to its initial state as the first pressing member 310 is lifted. Then, the housing 100 is placed at the memory slot position of the next location to be installed, and the above steps are repeated to complete the subsequent installation of the memory module.

[0080] During the installation process, since the length of the first pressing member 310 in the third direction is less than the length of the pluggable hardware 400 in the third direction. And along the third direction and in the direction pointing to the slot, the width of the first pressing member 310 in the first direction shows a decreasing trend. It can be ensured that the area of the pluggable hardware 400 other than the gold fingers does not directly contact the relatively hard contact member 220, effectively avoiding surface damage of the pluggable hardware 400 caused by rubbing, extending the service life of the pluggable hardware 400, and reducing equipment failures and maintenance costs caused by damage to the pluggable hardware 400.

[0081] To further define the length of the first pressing member 310 in the third direction and its relative position with the gold fingers of the pluggable hardware 400, this embodiment also uses the structure of the pluggable hardware 400 as a reference for explanation. Exemplarily, the pluggable hardware 400 includes a first part 410 and a second part 420. The first part 410 is connected to the first pressing member 310, and the second part 420 is provided with gold fingers. It should be noted that the second part 420 may not be connected to the first pressing member 310, or a part of the second part 420 may be connected to the first pressing member 310, and the connection at this time may be an abutment.

[0082] In the third direction, the length of the first pressing member 310 is less than the length of the pluggable hardware 400, and the length of the first pressing member 310 is greater than the length of the first part 410. In this way, part or all of the second part 420 can be exposed, facilitating the cleaning of the gold fingers of the pluggable hardware 400 by the contact member 220.

[0083] In some embodiments, such as Figure 2As shown, the number of the first pressing members 310 is two. The two first pressing members 310 are respectively located on both sides of the pluggable hardware 400 along the second direction and are detachably connected to the pluggable hardware 400.

[0084] With such a setting, when performing the plugging and unplugging operations, forces can be applied simultaneously from both sides of the pluggable hardware 400. Compared with applying force from a single side, applying force symmetrically from both sides can make the force distribution more uniform, effectively reducing problems such as tilting and shaking of the pluggable hardware 400 caused by uneven force, thereby significantly improving the stability and reliability of the plugging and unplugging process, ensuring that the pluggable hardware 400 can accurately and smoothly pass through the accommodation area, and largely preventing other areas of the pluggable hardware 400 except the gold fingers from coming into contact with and rubbing against the surrounding relatively hard contact members 220.

[0085] In some embodiments, the first pressing member 310 includes a first pressing section 311, a second pressing section 312, and an arc section 313 for connecting the first pressing section 311 and the second pressing section 312. Exemplarily, the first pressing section 311 and the second pressing section 312 are arranged at intervals along the first direction. One end of the arc section 313 is connected to one end of the first pressing section 311, and the other end of the arc section 313 is connected to one end of the second pressing section 312, and one end of the first pressing section 311 and one end of the second pressing section 312 are located on the same side, so that the first pressing member 310 forms a structure similar to a U shape.

[0086] The maximum dimension of the arc section 313 in the first direction is less than or equal to the vertical distance between the first pressing section 311 and the second pressing section 312 in the first direction. That is to say, the vertical distance between the end of the arc section 313 connected to the first pressing section 311 and the second pressing section 312 is the largest and is less than or equal to the vertical distance between the first pressing section 311 and the second pressing section 312 in the first direction. Then, the dimension of the arc section 313 in the first direction gradually decreases along the direction away from the first pressing section 311.

[0087] During the movement of the pluggable hardware 400, the arc section 313 of the first pressing member 310 plays a key role. Since its dimension gradually decreases along the direction away from the first pressing section 311, when interacting with the contact member 220, it can push open the contact member 220 in a progressive manner, enabling the contact member 220 to be smoothly pushed open, avoiding deformation or damage of the contact member 220 caused by sudden strong pushing open, and at the same time ensuring that other areas of the pluggable hardware 400 except the gold fingers do not rub against the contact member 220, protecting the integrity and electrical performance of the pluggable hardware 400, and improving the reliability and stability of the device.

[0088] In some embodiments, at least one of the two first pressing members 310 is provided with a first guiding portion, and the pluggable hardware 400 has a second guiding portion that cooperates with the first guiding portion. One of the first guiding portion and the second guiding portion is a guiding groove, and the other of the first guiding portion and the second guiding portion is a guiding protrusion.

[0089] The following takes the first guiding portion being a guiding groove as an example for description. When the pluggable hardware 400 is fully inserted into the slot, it is necessary to separate the housing 100 and the pressing assembly 300 from the pluggable hardware 400 to be. At this time, after the pressing assembly 300 is lifted by hand, the pluggable hardware 400 can move in the guiding groove. The guiding groove plays an accurate guiding and positioning role, ensuring that the pressing assembly 300 can move stably along a predetermined trajectory at the moment of separation, avoiding the position deviation of the pluggable hardware 400 or unnecessary external force impact caused by the separation action, thereby effectively protecting the physical structure and electrical connection of the pluggable hardware 400 and reducing the risk of damage to the pluggable hardware 400.

[0090] It should be understood that when the first pressing member 310 includes a first pressing section 311 and a second pressing section 312 arranged at intervals along the first direction, the guiding groove can be arranged on the first pressing section 311 and the second pressing section 312. The groove width of the guiding groove is equal to the width of the pluggable hardware 400.

[0091] It should be noted that in addition to the first pressing member 310, the pressing assembly 300 can also have other structures. Exemplarily, the pressing assembly 300 further includes a second pressing member 320. The second pressing member 320 is arranged on the side of the first pressing member 310 away from the housing 100 and is connected to the first pressing member 310. It should be noted that the connection between the first pressing member 310 and the second pressing member 320 in this embodiment can be a detachable fixed connection or a non-detachable fixed connection.

[0092] The first pressing member 310 and the second pressing member 320 surround to form an auxiliary accommodating area; the auxiliary accommodating area is used to place the pluggable hardware 400. That is to say, the auxiliary accommodating area can be similar to a U-shaped structure, and the pluggable hardware 400 can be installed in the auxiliary accommodating area. The structure of this pressing assembly 300 is highly adapted to the shape of the pluggable hardware 400. During the installation process, the operator can apply a force to the second pressing member 320 to accurately embed the pluggable hardware 400 into the auxiliary accommodating area, avoiding problems such as poor contact between the pluggable hardware 400 and the slot caused by installation position deviation, greatly improving the installation accuracy and reliability, and ensuring that the pluggable hardware 400 can work stably and efficiently.

[0093] It should be noted that the pluggable hardware 400 can be connected to the first pressing member 310 and the second pressing member 320 by plugging. Users do not need complex tools or professional skills. They only need to align the pluggable hardware 400 with the auxiliary accommodating area and insert it to complete the connection, which greatly shortens the installation time and improves work efficiency. At the same time, the plugging connection has a certain self-locking function, which can effectively prevent the pluggable hardware 400 from loosening and falling off during use, ensuring the stability of the connection.

[0094] In the embodiment of the present application, in the first direction, the width of the second pressing member 320 is B, and the width of the pluggable hardware is C, and B and C satisfy: 3C ≤ B ≤ 5C. Exemplarily, B is equal to 3C, 3.5C, 4C, 4.5C, 5C, and the area formed by any two of the above values.

[0095] In this way, the width of the second pressing member 320 is large enough to accommodate the pressing action, providing sufficient contact area for the operator's fingers. When the operator performs pressing, the fingers or pressing tool can be placed more comfortably on the second pressing member 320, with enough space for operation, reducing operation errors caused by insufficient space, and improving the accuracy and efficiency of the pressing operation.

[0096] In some embodiments, the pressing assembly 300 further includes a flexible member (not shown in the figure), and the flexible member is disposed on the side of the second pressing member 320 facing away from the first pressing member 310. Exemplarily, the flexible member can be bonded to the surface of the second pressing member 320 facing away from the first pressing member 310 by structural adhesive, and the material of the flexible member includes but is not limited to foam material. When the operator performs the pressing operation, the fingers will feel comfortable when contacting the foam, reducing the fatigue of the hand. Compared with a hard pressing surface, the foam material can provide better buffering, making the pressing process easier and smoother, and improving the comfort and pleasure of the operation. In addition, during the plugging and unplugging process, the instantaneous contact between the pluggable hardware 400 and the slot may generate minute vibrations. The porous structure of the foam can effectively absorb this part of mechanical energy, reducing the transmission of vibrations to the hand, thereby reducing the fatigue of the operator.

[0097] The above has introduced in detail a plugging and unplugging tool provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
