[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The core of the present invention is to provide a plug-in guide device, which has a simple and effective structure and can be applied to the field of server-related plug-in equipment. It can still ensure a good guiding effect when the component processing error is large, ensure reliable and accurate plug-in between structural parts, avoid component damage caused by improper plug-in of structural parts, and ensure the reliability of plug-in operation. Another core of the present invention is to provide a server including the above-mentioned plug-in guide device.

[0048] The plug-in guide device provided by the present invention comprises a first base shell 3, a second base shell 6, a guide groove 4, and a plug connector 5, wherein the first base shell 3 is electrically connected to the first board 1, and the second base shell 6 is electrically connected to the second board 2. The circuit conduction between the first board 1 and the second board 2 is achieved by plugging the guide groove 4 and the plug connector 5. Please refer to Figure 1 .

[0049] The guide groove 4 is arranged in the first base shell 3 and a floating space is provided between the guide groove 4 and the inner wall of the first base shell 3. The floating space is used to realize the operation requirement of the guide groove 4 floating in the first base shell 3. The guide groove 4 can float so that when it is plugged into the connector 5 in the second base shell 6, the two can have a floating adjustment space, so that the connector 5 and the guide groove 4 can be smoothly guided to ensure reliable plug-in.

[0050] In the case of large component processing errors, smooth guidance of the connector 5 and the guide groove 4 can be ensured during insertion, thereby avoiding damage to components due to inadequate guiding during insertion, ensuring reliable insertion of the connector 5 and the guide groove 4, and ensuring reliable circuit conduction between the first board 1 and the second board 2.

[0051] In a specific embodiment, floating spaces in multiple directions are provided between the guide groove 4 and the inner wall of the first base shell 3. When the connector 5 is plugged into the guide groove 4, the guide groove 4 can float in multiple directions when the connector 5 moves close to the guide groove 4. Through the floating of the guide groove 4, the connector 5 is guided to the correct position and reliably plugged into the guide groove according to the different force points when the connector 5 and the guide groove 4 are in contact.

[0052] Specifically, there are floating spaces in multiple directions, such as the upper side, lower side, left and right sides along the guide groove 4. Here, the upper, lower, left and right sides are based on the front and back of the plug-in direction of the guide groove 4 and the plug-in component 5. By setting the floating space, the plug-in component 5 and the guide groove 4 have greater flexibility when plugging, and the requirements for component processing accuracy are lower, thereby ensuring the reliability, flexibility and rapidity of the plug-in between the structural components.

[0053] The formation of a specific floating space can be achieved by using an elastomer, an elastic structure, etc., so that the guide groove 4 can move toward the floating space to form an adjustment space when the connector 5 is plugged in, thereby ensuring the smooth guiding effect of the guide groove 4 on the connector 5 when it is plugged in.

[0054] In a specific embodiment, if the connection between three structural members is realized, a reliable guiding effect can be achieved by two sets of guide grooves 4 and connectors 5. Specifically, if three structural members are arranged side by side, the structural member on the left is connected to the connector 5, the structural member in the middle is connected to the two guide grooves 4, and the structural member on the right is connected to the connector 5, and the left and right connectors 5 are respectively connected to the two guide grooves 4 on the middle structural member. Since the guide groove 4 can float, it can provide floating adjustment space during plugging, ensuring reliable contact and smooth guidance between the guide groove 4 and the connector 5, and ensuring the reliability of the connection between the structural members. These three structural members are only for illustration, and the structure of the guide groove 4 and the connector 5 of the present invention can also be applied to reliable guiding plug-in between four structural members or more structural members.

[0055] Furthermore, the relay controller electrically connects at least one of the guide slot 4 and the connector 5 to align and reliably connect the connector 5 and the guide slot 4 through magnetic force. The alignment here means inserting the connector 5 into the guide slot 4 in the guiding direction of the guide slot 4.

[0056] In a specific embodiment, the relay controller is connected to the guide slot 4, and the connector 5 is made of metal. The guide slot 4 is energized to make it magnetic to adsorb the connector 5, thereby ensuring the precise adsorption and combination of the guide slot 4 and the connector 5 during the contact process.

[0057] In another specific embodiment, the relay controller is connected to the connector 5 to make the connector 5 have magnetic force, and the guide groove 4 is made of metal. The connector 5 is energized to make it magnetic so as to adsorb the guide groove 4, thereby ensuring the precise adsorption and combination of the guide groove 4 and the connector 5 during the contact process.

[0058] In another specific embodiment, the relay controller connects the connector 5 and the guide slot 4. The connector 5 and the guide slot 4 have opposite magnetic poles. When the connector 5 and the guide slot 4 are energized, a mutual attractive force can be formed to ensure the precise adsorption and bonding of the guide slot 4 and the connector 5 during the contact process.

[0059] In another specific embodiment, the relay controller connects the connector 5 and the guide slot 4, and the connector 5 and the guide slot 4 have the same magnetic poles. When the connector 5 and the guide slot 4 are energized, a mutually repelling force can be formed. Either the connector 5 or the guide slot 4 is energized to ensure the precise adsorption and bonding of the guide slot 4 and the connector 5 during the contact process, and both the connector 5 and the guide slot 4 are energized to provide assistance for pulling out both.

[0060] In order to ensure reliable plugging of the guide groove 4 and the plug-in component 5, a spring sheet can be arranged in the guide groove 4. After the guide groove 4 and the plug-in component 5 are plugged in, the spring sheet is pressed to provide a pressing force to prevent the two from falling off during movement or transportation, which affects the transmission of signals and circuits. The specific position of the spring sheet can be set at the front end and / or the rear end of the guide groove 4, and can be set based on not interfering with the plug-in operation and providing a reliable pressing force.

[0061] The above-mentioned guiding device, through the setting of magnetic force and floating space, enables the guide groove 4 and the connector 5 to have a larger floating adjustment space when plugging together, thereby ensuring reliable and smooth guidance during the plugging operation, ensuring the reliability, speed and accuracy of the plugging, ensuring the reliability of the circuit conduction between the first board 1 and the second board 2, avoiding damage to components due to improper plugging or guiding errors, and avoiding signal or circuit transmission problems between structural parts due to misalignment of plugging; the plugging and unplugging of structural parts is achieved through a relatively simple structure, the structure is simple and has a reliable service life.

[0062] Based on the above embodiments, please refer to Figure 1 The relay controller connects the guide slot 4 and the connector 5 to control the on and off of the magnetic force, and the guide slot 4 and the connector 5 have the same magnetic poles.

[0063] When the guide groove 4 and the connector 5 are plugged in, the relay controller energizes the guide groove 4 to generate magnetic force to attract the connector 5. At this time, the connector 5 is in a power-off state. The magnetic force generated by the guide groove 4 can make the connector 5 quickly and accurately adsorbed into place. After being adsorbed into place, pushing the guide groove 4 or the connector 5 can make the two reliably and accurately plugged in, avoiding the situation where the components are damaged due to excessive insertion and extraction force.

[0064] When the guide groove 4 and the connector 5 are disconnected, the relay controller energizes both the guide groove 4 and the connector 5, so that the two produce a mutually repelling force, providing assistance for the removal of the component. The guide groove 4 and the connector 5 can be quickly separated by a small force, avoiding damage to the components due to excessive insertion and extraction force.

[0065] On the basis of providing a floating space between the guide groove 4 and the first base shell 3, combined with the relay controller to control the power supply of the guide groove 4 and the connector 5, reliable and smooth guiding of the guide groove 4 and the connector 5 during plugging is guaranteed, and low requirements on the processing accuracy of the components are set to avoid the problem of component damage caused by excessive plugging and unplugging force. The function of guiding to assist plugging and reverse pulling out can be provided, and plugging and unplugging can be saved time and effort.

[0066] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The guide slot 4 includes a first magnetic suction port 42 extending from the first base housing 3, and the first magnetic suction port 42 is connected to the relay controller; the first magnetic suction port 42 is made of a copper coil soft magnetic material, and the relay controller controls its power on and off to realize the presence or absence of magnetic force. After the relay controller controls the first magnetic suction port 42 to be powered on, the first magnetic suction port 42 can use magnetic force to reliably and accurately adsorb the plug-in component 5, ensuring reliable and accurate circuit connection between the first board 1 and the second board 2, and ensuring the docking effect.

[0067] The size and position of the first magnetic suction port 42 may be specifically configured in coordination with the connector 5 without any further restrictions.

[0068] A guide portion 43 is provided on one side of the first magnetic suction port 42 away from the first base housing 3, and the guide portion 43 gradually decreases in size in the direction close to the first magnetic suction port 42. When the plug-in component 5 and the guide groove 4 are plugged in, the guide portion 43 first contacts the plug-in component 5. The setting of the guide portion 43 and the elastic component 7 ensures that the plug-in component 5 has a larger floating range when assembled and matched, realizes more accurate guide limit, and ensures that the plug-in component 5 has a better guide effect when plugged in.

[0069] Taking a specific implementation as an example, the guide portion 43 has a guide angle of 60°, which facilitates the connector 5 to smoothly enter the first magnetic suction port 42 through this guide angle, thereby achieving reliable connection between the guide groove 4 and the connector 5, and ensuring effective circuit conduction between the first board 1 and the second board 2.

[0070] On the basis of any of the above embodiments, a second magnetic suction port 62 is provided in the second base shell 6 , and the relay controller controls the on and off of the magnetic force of the connector 5 by controlling the power supply of the second magnetic suction port 62 .

[0071] Please refer to Figure 4A second magnetic suction port 62 is provided in the second base shell 6. The second magnetic suction port 62 is made of a copper coil soft magnetic material. The second board 2 is energized by the relay controller, and then the second magnetic suction port 62 of the second base shell 6 electrically connected to the second board 2 is energized, and then the connector 5 is further made to generate magnetic force.

[0072] When both the first magnetic suction port 42 and the second magnetic suction port 62 are energized, the magnetic head 51 of the connector 5 has a magnetic suction force, which forms a repulsive and opposing effect with the anti-magnetic suction force of the first magnetic suction port 42, thereby providing a reverse thrust assisting force when the second board 2 is pulled out, saving time and effort.

[0073] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 An elastic member 7 is provided between the guide groove 4 and the first base shell 3. The guide groove 4 is floatingly connected to the first base shell 3 through the elastic member 7. Specifically, the elastic member 7 is arranged in the floating space. Through the expansion and contraction and floating functions of the elastic member 7, the guide groove 4 can be in a floating state. The plug-in connector 5 can be guided according to the different force points when the plug-in connector 5 is plugged in, ensuring that the guides of the plug-in connector 5 and the guide groove 4 are aligned, ensuring the reliable stability of the docking of the first board 1 and the second board 2, and avoiding poor plug-in.

[0074] Specifically, the elastic member 7 may be a spring, a rubber pad, a spring sheet, etc., and may have a certain elasticity to achieve a floating effect of the guide groove 4 .

[0075] Taking the elastic member 7 as a spring as an example, the expansion and contraction direction of the spring is perpendicular to the plugging direction of the guide groove 4 and the plugging member 5. If the plugging direction is the front-to-back direction ( Figure 1 The spring can be extended and retracted in the left-right direction or in the up-down direction.

[0076] In a specific embodiment, the expansion and contraction direction of the spring is left and right. For example, a spring can be arranged between the left side of the guide groove 4 and the first base shell 3, or between the right side of the guide groove 4 and the first base shell 3, or between the left and right sides of the guide groove 4 and the first base shell 3. The expansion and contraction function of the spring can realize that the guide groove 4 can be arranged in the first base shell 3 in a floating manner left and right, and a floating adjustment space can be provided when the guide groove 4 and the connector 5 are plugged in to ensure the alignment of the two, ensure that the guide groove 4 can provide a smooth and reliable guiding effect for the plug-in of the connector 5, and ensure that the guide groove 4 and the connector 5 are reliably and accurately plugged in.

[0077] In another specific embodiment, the expansion and contraction direction of the spring is the up-down direction, such as a spring can be arranged between the upper side of the guide groove 4 and the first base housing 3, or between the lower side of the guide groove 4 and the first base housing 3, or between the upper and lower sides of the guide groove 4 and the first base housing 3, and the effect that the guide groove 4 can be arranged in the first base housing 3 in an up-down floating manner is achieved through the expansion and contraction function of the spring. When the plug-in 5 and the guide groove 4 are plugged in, a smooth and reliable guiding effect can be provided to ensure reliable and accurate plugging of the guide groove 4 and the plug-in 5.

[0078] In another specific embodiment, the expansion and contraction directions of the spring are up and down and left and right directions, that is, springs can be set on the upper and lower, left and right sides of the guide groove 4, so that the guide groove 4 can float on the upper and lower, left and right sides, and can provide a smooth and reliable guiding effect when the connector 5 and the guide groove 4 are plugged in, thereby ensuring reliable and accurate plugging of the guide groove 4 and the connector 5.

[0079] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 A groove is provided in the circumference of the guide groove 4 or in the inner wall of the first base shell 3, one end of the elastic member 7 is provided in the groove, and the other end of the elastic member 7 is connected to the first base shell 3 or the guide groove 4. The connection between the two ends of the elastic member 7 and the corresponding parts can be welded, abutted or detachably connected, such as the elastic member 7 can abut the bottom surface of the groove, the elastic member 7 can be welded to the groove, and the elastic member 7 can be clamped in the groove.

[0080] The specific groove can be circular, square or irregular in shape, and the groove is set to provide space and position for fixing the elastic member 7. The depth of the groove can be set so as not to affect the strength of the shell and to provide installation space.

[0081] In a specific embodiment, a groove is provided in the circumference of the guide groove 4, one end of the elastic member 7 is provided in the groove, and the other end is connected to the first base housing 3, and the elastic member 7 is sleeved on the pin needle 41 provided in the groove. The groove, the pin needle 41, and the first base housing 3 jointly limit the extension direction of the elastic member 7 and fix the elastic member 7, thereby ensuring effective control of the floating direction of the guide groove 4 and ensuring reliable plugging of the guide groove 4 and the plug-in member 5.

[0082] In another specific embodiment, a groove is provided on the inner wall of the first base housing 3, one end of the elastic member 7 is provided in the groove, and the other end is connected to the guide groove 4, and the elastic member 7 is sleeved on the pin 41 provided in the groove. The elastic member 7 is fixed and limited by the groove, the pin 41, and the first base housing 3, so as to ensure effective control of the floating direction of the guide groove 4 and reliable plugging of the guide groove 4 and the plug-in member 5.

[0083] The height of the pin 41 is less than or equal to the depth of the groove, which has the effect of limiting the elastic member 7 and does not interfere with the compression process of the elastic member 7, thereby ensuring stability and reliability during the plug-in operation.

[0084] Based on any of the above embodiments, at least one of the connector 5 and the guide groove 4 is provided with a limiter for limiting the moving distance of the connector 5 relative to the guide groove 4. The limiter ensures the reliability of the plug-in process and avoids collision damage between components.

[0085] Specifically, in one embodiment, a limit piece is provided on the connector 5. When the connector 5 moves to be plugged into the guide groove 4, when the limit piece contacts the guide groove 4, it indicates that the connector has been plugged into place, thereby preventing collision or damage of components caused by excessive plugging.

[0086] In another embodiment, a limiting member is provided on the guide groove 4, and when the plug-in component 5 moves to be plugged into the guide groove 4, when the limiting member and the plug-in component 5 are in contact, it indicates that the plug-in is in place, thereby preventing the collision or damage of components caused by excessive plug-in. The limiting member can be specifically provided at the bottom of the guide groove 4, and the buffering and limiting effects are achieved by the limiting member.

[0087] In another embodiment, limit members are provided on both the connector 5 and the guide groove 4. When the connector 5 is inserted into the guide groove 4, the limit members on both sides contact each other, indicating that the connector is in place and no further movement is required, thereby preventing collision or damage of components caused by excessive insertion.

[0088] Based on any of the above embodiments, please refer to Figure 1 , Figure 4 The connector 5 is provided with a limit pad 8 and a stopper 9, that is, the limiter is specifically a limit pad 8 and a stopper 9, the limit pad 8 and the stopper 9 are respectively located in the front and rear directions of the second base shell 6, and the front and rear directions of the second base shell 6 are the plugging directions of the connector 5 and the guide groove 4, as shown in FIG. Figure 1 The direction indicated by the arrow is the front-to-back direction. By respectively arranging a limit pad 8 and a stop member 9 for limiting in the front-to-back direction of the second base shell 6, the plugging distance between the connector 5 and the guide groove 4 is limited to avoid wear or collision of components due to excessive plugging force or over-limit plugging, thereby ensuring the reliability of the plugging operation, ensuring the long-term reliable guiding effect of the guide device, and ensuring the service life of the guide device.

[0089] Specifically, the limiting pad 8 and the stop member 9 can be configured as components with buffering and limiting effects such as rubber pads, and their specific locations can be configured according to actual operating conditions without limitation.

[0090] Taking a specific implementation as an example, a mounting notch is provided on the connector 5 for mounting a limit pad 8 and a stop member 9. If the limit pad 8 and the stop member 9 are damaged, they can be replaced and repaired by themselves.

[0091] Taking another specific implementation as an example, the limiting pad 8 and the stopper 9 are both connected to the connector 5 by hot-melt, and the limiting pad 8, the stopper 9 and the connector 5 form an integrated structure.

[0092] Specifically, when the limiting pad 8 contacts the rear end surface of the guide groove 4 , the stop member 9 contacts the rear end surface of the second base shell 6 , corresponding to the state where the guide groove 4 and the connector 5 are plugged into place.

[0093] When the limiting pad 8 contacts the front end surface of the second base shell 6 , the stop member 9 leaves the contact with the rear end surface of the second base shell 6 , corresponding to the limit position of movement of the connector 5 after being pulled out from the guide groove 4 .

[0094] By setting the stopper 9 and the limiting pad 8, the guide groove 4 and the connector 5 are limited when they are plugged in, preventing the first board 1 and the second board 2 from collision and damage during insertion, and achieving the limiting effect when the connector 5 is pulled out of the guide groove 4.

[0095] Please refer to Figure 4 , a second magnetic suction port 62 is arranged in the second base shell 6. The second magnetic suction port 62 is arranged at the front end of the second base shell 6 and is made of a copper coil soft magnetic material. When the second magnetic suction port 62 is energized, the connector 5 obtains magnetic force. Through the connection between the relay controller and the second magnetic suction port 62, when the relay controller controls the second magnetic suction port 62 to be energized, the force of the second magnetic suction port 62 and the force of the first magnetic suction port 42 repel each other, providing assistance for the separation of the guide groove 4 and the connector 5, making it convenient for the operator to separate the two in a time-saving and labor-saving manner. When the relay controller controls the second magnetic suction port 62 to be powered off, the force of the first magnetic suction port 42 can reliably adsorb the connector 5 located in the second magnetic suction port 62, ensuring the reliable plug-in of the connector 5 and the guide groove 4.

[0096] Please refer to Figure 4 When the guide slot 4 and the connector 5 are plugged in, there is a distance between the limit pad 8 and the second magnetic suction port 62, which is the maximum moving distance of the connector 5 when it is pulled out from the guide slot 4, to avoid pulling out too much. Here, the connector 5 is pulled out from the guide slot 4, corresponding to the first board 1 and the second board 2 being disconnected.

[0097] Please refer to Figure 3 , Figure 4The first base housing 3 has a first welding pin 31 for connecting to the first board 1 at the bottom, and the second base housing 6 has a second welding pin 61 for connecting to the second board 2 at the bottom, so as to ensure reliable connection between the first base housing 3 and the first board 1, and between the second base housing 6 and the second board 2. Furthermore, the first base housing 3 and the second base housing 6 are both made of copper, so as to ensure the conductivity and reliability of the guide slot 4 and the connector 5.

[0098] The front end of the connector 5 is a magnetic head 51 which is plugged into the guide groove 4. The front end of the magnetic head 51 is provided with a guide surface corresponding to the guide portion 43. The guide surface is close to the guide portion 43 and the guiding effect of the guide portion 43 and the floating setting of the guide groove 4 ensure the reliability, flexibility and accuracy of the magnetic head 51 and the first magnetic suction port 42 when docking.

[0099] The diameters of the limiting pad 8 and the stopper 9 are both larger than the diameter of the second magnetic suction opening 62 , thereby ensuring reliable limiting of the connector 5 during plugging and unplugging, and avoiding collision damage of the components.

[0100] The diameter of the magnetic head 51 is smaller than or equal to the diameter of the second magnetic suction port 62 , so that the magnetic head 51 can move relative to the second magnetic suction port 62 for plugging and unplugging operations.

[0101] The groove corresponding to the elastic member 7 is specifically arranged in the circumference of the guide groove 4, one end of the elastic member 7 is connected to the groove, and the other end is connected to the first base shell 3. Under the premise that the first base shell 3 is a frame structure, at least one elastic member 7 is arranged on the inner wall of the upper, lower, left and right sides of the first base shell 3. If one of the elastic members 7 fails, the other elastic members 7 can still ensure normal and reliable operation; by arranging multiple elastic members 7, the guide groove 4 has a more flexible floating space, ensuring a reliable and smooth guiding effect on the plug-in of the plug-in 5.

[0102] Specifically, if two elastic members 7 are disposed on an inner wall of the first base shell 3 , the two elastic members 7 may be disposed in one groove, or two grooves may correspond to the two elastic members 7 .

[0103] Based on any of the above embodiments, please refer to Figure 4 The rear end of the connector 5 is a push-pull portion 52 , which is arranged away from the rear end surface of the second base housing 6 and is used to assist the plugging and unplugging operations of the connector 5 and the guide groove 4 .

[0104] Specifically, during the plug-in operation, the first board 1 remains stationary, and the second board 2 drives the connector 5 to move toward the guide slot 4. Under the action of the guide portion 43 and the floating space, the guide slot 4 and the connector 5 are aligned. Further, the guide slot 4 is powered to obtain magnetic force, so that the connector 5 is quickly adsorbed on the guide slot 4, and further the push-pull portion 52 is used to push the connector 5 to be quickly plugged into place.

[0105] During the unplugging operation, the first board 1 remains stationary, and obtains a repulsive force through the guide slot 4 and the connector 5 to provide an assist for unplugging, and further the guide slot 4 and the connector 5 are quickly separated by pulling the push-pull portion 52 to achieve the separation of the first board 1 and the second board 2.

[0106] Specifically, the push-pull portion 52 may be provided with a handle, anti-slip texture, a grip, etc., which is convenient for the operator to manually operate.

[0107] Based on any of the above embodiments, please refer to Figure 5 , Figure 1 , Figure 3 , Figure 4 The guide device also includes a front control panel 11 for signal connection between the first board 1 and the second board 2. The relay controller signal is connected to the front control panel 11. The front control panel 11 can be a control panel on the front side of the server. An operation key is set on the front control panel 11 to control whether the first magnetic suction port 42 and the second magnetic suction port 62 are powered to cooperate with the plugging and unplugging operations of the guide slot 4 and the connector 5.

[0108] Specifically, the front control panel 11 is provided with a button assembly 12 , and the button assembly 12 is used to control the on and off of the magnetic force of the first magnetic suction port 42 and the second magnetic suction port 62 .

[0109] In specific applications, when the guide groove 4 and the connector 5 are not in contact, when the second board 2 moves relative to the first board 1 for insertion, the second board 2 moves with the connector 5. When the connector 5 is about to contact the guide groove 4, the insertion may be misaligned due to insufficient precision of some processing dimensions or other processing reasons. The following three methods can be used to ensure reliable insertion in the case of misalignment. First, when the magnetic head 51 contacts the guide part 43, the 60° chamfer of the guide part 43 can be used to cover the error of its deviation; second, by pressing the button corresponding to the first magnetic suction port 42 on the button assembly 12, the first magnetic suction port 42 in the guide groove 4 has a magnetic suction force, which can adsorb the unpowered magnetic head 51 and cover the error of the deviation during the second insertion; third, under the action of the elastic member 7, comprehensive and precise guidance in multiple directions can be achieved, which can relax the standard of the machining accuracy of the structural parts, make it easier to accurately guide, and achieve good insertion; when the first magnetic suction port 42 attracts the magnetic head 51, the second board 2 continues to move forward, and under the action of the limit pad 8, it is stopped and anti-collision to avoid collision damage between components.

[0110] When the first board 1 and the second board 2 need to be separated, the button corresponding to the second magnetic suction port 62 on the button assembly 12 is pressed so that the second magnetic suction port 62 has a magnetic suction force opposite to that of the first magnetic suction port 42. At this time, the forces of the first magnetic suction port 42 and the second magnetic suction port 62 form a repulsive force. When the second board 2 is pulled out, there will be a reverse thrust force, so that the operator can easily pull it out.

[0111] Based on any of the above embodiments, the front control board 11 is connected to the first board 1 and the second board 2 through the main board 10 signal. Please refer to Figure 5 , Figure 5 The dotted line portion corresponds to the method of implementing circuit signal transmission by plugging in the plug-in board.

[0112] Or, the front control board 11 is connected to the first board 1 and the second board 2 through a signal line, please refer to Figure 5 , Figure 5 The solid line portion corresponds to the signal line transmission method to realize circuit control.

[0113] The above-mentioned plug-in guide device realizes reliable plugging and unplugging between structural parts through a simple and effective structure. Firstly, it can solve the problem of poor plugging and unplugging between structural parts; secondly, it can ensure accurate guidance during plugging and unplugging when the processing error is large; thirdly, it can realize the role of guiding assist and reverse thrust, assisting the operator to perform time-saving and labor-saving operations, improve the convenience of use, and enhance the user experience.

[0114] The present invention also provides a server, comprising the plug-in guide device described in any of the above embodiments, a first board card 1, and a second board card 2, wherein the circuit conduction and disconnection between the first board card 1 and the second board card 2 are both achieved through the plug-in guide device.

[0115] Specifically, when the guide slot 4 and the connector 5 are plugged in, the circuit between the first board 1 and the second board 2 is connected, and when the guide slot 4 and the connector 5 are separated, the circuit between the first board 1 and the second board 2 is disconnected.

[0116] When the guide slot 4 and the connector 5 are aligned by magnetic control, the first board 1 and / or the second board 2 are powered on by the electromagnetic controller in the server, so that the guide slot 4 and / or the connector 5 obtain magnetic force to assist the plugging and unplugging operation.
