Description

Technical Field

[0001] This invention relates to the field of interface mis-insertion prevention technology, specifically to an interface mis-insertion prevention protection device for information technology equipment. Background Technology

[0002] In today's digital age, information technology equipment is widely used in various fields, from personal offices to enterprise data centers and large research institutions. These devices are equipped with a variety of interfaces to connect to different external devices, enabling functions such as data transmission and charging. However, with technological advancements, the types of information technology equipment and their interfaces are increasing. Some interfaces are similar in shape and size, which can easily lead to misconnection and equipment malfunction or damage. Therefore, physical limits or signal recognition mechanisms are typically used to prevent incorrect insertion of different types of interfaces.

[0003] Mis-insertion of interfaces often occurs because the interface information cannot be clearly distinguished during connection. Existing interface mis-insertion protection devices typically prevent insertion to avoid mis-insertion, rather than directly indicating the interface information during connection to identify the interface and prevent mis-insertion.

[0004] To address the aforementioned issues, a device for preventing mis-insertion of information technology equipment interfaces is proposed. Summary of the Invention

[0005] 1. Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an interface mis-insertion protection device for information technology equipment. It has the advantages of directly indicating interface information during interface insertion, making it easy to identify interface information, and solves the problem of not being able to directly indicate interface information during interface insertion to identify the interface and avoid mis-insertion.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an anti-misinsertion protection device for an information technology equipment interface, comprising a protective shell made of rigid plastic and fixedly installed inside the information technology equipment interface by screws; an anti-misinsertion pressure plate made of elastic material is fixedly connected to the middle of the top of the protective shell; a push plate for transmitting power is engaged at the top of the anti-misinsertion pressure plate; an interface indicator piece for marking interface information is attached to one end of the push plate; an LED bead for illuminating the interface indicator piece is fixedly installed inside the interface indicator piece; the LED bead is electrically connected to a microelectronic chip for power supply and control; the microelectronic chip is signal-connected to a proximity switch for signal sensing; a sensing metal piece is fixedly installed inside the protective shell on one side of the proximity switch; and a stop ring made of elastic material is fixedly installed inside the protective shell.

[0007] Preferably, the top of the protective shell has a movable groove for storing the interface indicator piece, and the bottom of the movable groove has a squeezing movable groove for guiding the anti-misinsertion pressure piece.

[0008] Specifically, the protective shell (ABS rigid plastic injection molding) has a movable groove in the middle of its top to accommodate the interface indicator piece. A compression groove is also provided in the middle of the bottom of the movable groove to guide the movement of the anti-misinsertion pressure piece. The ABS material combines rigidity and toughness, protecting the internal structure from insertion and removal impacts. The movable groove provides expansion and contraction space for the interface indicator piece, ensuring smooth ejection and retraction. The angled design of the compression groove guides the tilting deformation of the anti-misinsertion pressure piece, allowing the pressure when the connector is inserted to be efficiently transmitted to the push plate. The overall structure integrates interface protection and anti-misinsertion indication, avoiding structural redundancy caused by separate protection.

[0009] Preferably, the anti-misinsertion pressure plate is inclinedly disposed inside the protective shell, the anti-misinsertion pressure plate is located below the interface indicator plate, the movable end of the anti-misinsertion pressure plate has a slot for positioning it, and the top end of the anti-misinsertion pressure plate has a locking groove for engaging the push plate.

[0010] Specifically, the anti-misinsertion pressure plate (made of silicone rubber) is installed at an angle inside the protective shell, below the interface indicator plate. The movable end has a slot for engaging with the guide block, and the top has a locking groove for engaging and fixing with the push plate. The high elasticity of the silicone rubber material ensures quick reset after the connector is pulled out. The tilt angle allows the pressure when the connector is inserted to be efficiently converted into lateral thrust. The slot engages with the guide block to position the interface indicator plate after it pops out, preventing the indicator plate from shaking and affecting observation. The locking groove engages and fixes with the push plate to ensure the stability of force transmission and prevent the push plate from falling off during insertion and removal. The tilt setting also makes the anti-misinsertion pressure plate have a buffering effect, reducing the impact when the connector is inserted.

[0011] Preferably, the push plate includes an extrusion plate made of elastic material and a smooth guide wheel for guiding. The extrusion plate is engaged inside the anti-misinsertion pressure plate. The top end of the extrusion plate is rotatably connected to a smooth guide wheel that fits into the protective shell. The end of the extrusion plate away from the anti-misinsertion pressure plate is fitted with an interface indicator plate.

[0012] Specifically, the extrusion plate (polyurethane elastic material) of the push plate engages with the locking groove of the anti-misinsertion pressure plate, and the top is rotatably connected to a smooth guide wheel (nylon material), which fits against the movable groove wall of the protective shell. The end of the extrusion plate away from the anti-misinsertion pressure plate is fitted with the interface indicator plate. The polyurethane extrusion plate has both elasticity and rigidity, which can buffer the pushing force of the anti-misinsertion pressure plate and avoid structural damage caused by rigid contact. The smooth guide wheel converts the sliding friction between the extrusion plate and the protective shell into rolling friction, reducing the resistance of the indicator plate popping out and retracting. The snap-fit ​​connection ensures that the push plate and the anti-misinsertion pressure plate move synchronously and there is no deviation during the force transmission process.

[0013] Preferably, the interface indicator includes a tension spring providing tension, an information piece marking interface information, and a guide block for guiding and positioning. The tension spring is fixedly installed inside the protective housing. One end of the tension spring is fixedly installed with a guide block that moves inside the protective housing. A guide block that moves inside the protective housing is fixedly connected to the middle of the guide block near the end of the tension spring. One end of the guide block has a protrusion that engages with a slot. During the process of the information piece being pushed out, the anti-misinsertion pressure piece is deformed horizontally by the joint, and the information piece... During movement, the guide block engages with the anti-misinsertion pressure plate inside the slot to lock and position it. When no indication is needed, the information piece is pushed to release the guide block from engaging the anti-misinsertion pressure plate, allowing the information piece to reset under the action of the tension spring. The anti-misinsertion pressure plate also resets under its own elasticity. The top of the information piece, away from the tension spring, has an information groove for writing interface information. The bottom of the information groove has several light-transmitting holes. Below the light-transmitting holes, there is an illumination groove for installing LED beads. One end of the illumination groove is fixed with a disassembly piece by screws.

[0014] Specifically, the tension spring (made of piano wire) of the interface indicator is fixed inside the protective shell, and the guide block is fixed to one end of the tension spring and can slide along the guide groove of the protective shell. One end has a boss to fit the slot. The information sheet (made of transparent PC material) has an information groove on the top of the end away from the tension spring to engrave the interface information, a light-transmitting hole at the bottom, and an illumination slot below. One end is fixed to the disassembly piece with a screw. The tension spring provides the reset force to ensure that the interface indicator automatically resets after popping out. The boss and the slot engage to position the indicator and prevent it from shaking after popping out. The information groove of the transparent PC information sheet clearly shows the interface type. The light-transmitting hole, together with the LED beads, provides illumination in dim environments. The disassembly piece facilitates the maintenance and replacement of the LED beads. The overall structure combines the visualization of interface information with the positioning to prevent misinsertion, improving the accuracy of insertion and removal.

[0015] Preferably, the LED beads are fixedly installed in the lighting slot inside the information sheet, the proximity switch is fixedly installed at the top of the information sheet, the proximity switch is located on the outside of the information slot near the tension spring, and the sensing metal sheet is fixedly installed at the top of the movable slot inside the protective shell on the side away from the tension spring.

[0016] Specifically, the LED beads (surface mount type) are fixed inside the lighting slot of the information chip, the proximity switch (Hall effect type, connected to the microelectronic chip signal) is fixed at the top of the information chip, located on the outside of the information slot near the tension spring, and the sensing metal plate (stainless steel material) is fixed at the top of the protective shell's movable slot on the side away from the tension spring. The distance between the sensing metal plate and the proximity switch is adjustable. The LED beads provide directional lighting, accurately illuminating the information slot, facilitating interface identification in dim environments. The Hall effect proximity switch controls the switching of the LED beads by changing the distance to the sensing metal plate, achieving automated lighting. The stainless steel sensing metal plate is corrosion resistant, ensuring the detection stability of the proximity switch. The microelectronic chip performs signal processing and power supply control, avoiding energy waste caused by the LED beads being constantly on.

[0017] Preferably, the stop ring is located at the end of the protective shell on the side where it is inserted into the interface of the information equipment. The cross-section of the stop ring is set as a conical structure, and the conical end of the stop ring faces the inside of the protective shell, and the size of the conical end face is smaller than the size of the inner wall of the protective shell.

[0018] Specifically, the retaining ring (made of silicone rubber) is fixed to the end of the protective shell that is inserted into the interface of the information equipment. The conical end face faces the inside of the protective shell, and the size of the conical end face is smaller than the size of the inner wall of the protective shell. The elasticity of the silicone rubber material allows the retaining ring to deform as the connector is inserted. When the interface is not confirmed, the conical structure provides pre-tightening resistance to prevent the connector from being fully inserted. After confirming that the interface is correct, increasing the insertion force can deform the retaining ring, allowing the connector to be fully inserted. The guiding effect of the conical end face guides the connector to accurately align with the interface, while the sealing performance prevents dust from entering the interface. The elastic material buffers the impact when the connector is inserted, protecting the interface pins.

[0019] (III) Beneficial Effects Compared with the prior art, the present invention provides an interface protection device for information technology equipment to prevent mis-insertion, which has the following beneficial effects: This is an interface mis-insertion protection device for information technology equipment. A protective shell is fixed inside the interface of the information technology equipment with screws, forming an interface connection protection ring within the shell. During interface connection, the connector, when inserted into the interface, first enters the protective shell and presses against the mis-insertion protection plate until it touches the stop ring. The anti-mis-insertion plate then pushes the interface indicator plate out of the protective shell via a push plate. The interface information on the indicator plate clearly identifies the interface, preventing the connector from being fully inserted before it is stopped by the stop ring. The device determines whether the connection is correct based on the interface information. If correct, the connection force is increased to press the connector against the stop ring, completing the connection. If the connection is incorrect, the connector can be pulled out.

[0020] This information technology equipment interface mis-insertion protection device has LED beads installed inside the interface indicator piece to illuminate the interface information, as well as a proximity switch to control its on / off state. By using the positional relationship between the proximity switch and the sensing metal piece, the LED beads are turned on to illuminate when the interface indicator piece is extruded for identification, and turned off when it is retracted into the protective shell and no longer indicating, thus extending the service life, facilitating the identification of interface information in dim environments, and improving the stability of the mis-insertion protection device.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5An information technology equipment interface anti-misinsertion protection device includes a protective shell 1 made of rigid plastic that is fixedly installed inside the information technology equipment interface by screws. An anti-misinsertion pressure plate 2 made of elastic material is fixedly connected to the middle of the top of the protective shell 1. A push plate 3 for transmitting power is engaged at the top of the anti-misinsertion pressure plate 2. An interface indicator plate 4 marked with interface information is attached to one end of the push plate 3. An LED bead 5 for illuminating the interface indicator plate 4 is fixedly installed inside the interface indicator plate 4. The LED bead 5 is electrically connected to a microelectronic chip that powers and controls it. The microelectronic chip is signal connected to a proximity switch 6 for signal sensing. A sensing metal plate 7 is fixedly installed inside the protective shell 1 on one side of the proximity switch 6. A stop ring 8 made of elastic material is fixedly installed inside the protective shell 1.

[0025] Preferably, the top of the protective shell 1 has a movable groove for storing the interface indicator 4 in the middle, and the bottom of the movable groove has a squeezing movable groove for guiding the anti-misinsertion pressure plate 2 in the middle.

[0026] Specifically, the protective shell 1 (ABS rigid plastic injection molding) has a movable groove in the middle of its top to accommodate the interface indicator 4. A compression movable groove is provided in the middle of the bottom of the movable groove to adapt to the guiding movement of the anti-misinsertion pressure plate 2. The ABS material has both rigidity and toughness, which can protect the internal structure from the impact of insertion and removal. The movable groove provides the interface indicator 4 with expansion and contraction space to ensure that the indicator 4 pops out and is stored smoothly. The tilt design of the compression movable groove guides the tilt deformation of the anti-misinsertion pressure plate 2, so that the pressure when the connector is inserted is efficiently transmitted to the push plate 3. The overall structure realizes the integration of interface protection and anti-misinsertion indication, avoiding the structural redundancy caused by separate protection.

[0027] Based on the structural limiting principle, the movable groove restricts the movement direction of the interface indicator 4 (extension and contraction only in the horizontal direction) through size matching. The inclination angle of the extrusion movable groove is based on the mechanical transmission principle, which converts the axial insertion force of the connector into the lateral thrust of the anti-misinsertion pressure plate 2. The protection principle of ABS material is based on material rigidity to resist mechanical damage during external insertion and removal. At the same time, the insulation avoids short circuits. When not inserted or removed, the interface indicator 4 is stored in the movable groove of the protective shell 1, and the anti-misinsertion pressure plate 2 is placed at an angle in the extrusion movable groove. When the connector is inserted, the anti-misinsertion pressure plate 2 is squeezed along the extrusion movable groove, causing it to deform and push the push plate 3, thereby pushing the interface indicator 4 out of the movable groove. After insertion or removal, the interface indicator 4 is reset under the action of the tension spring 41 and retracts into the movable groove. The inner wall of the movable groove is cleaned regularly (to prevent dust accumulation), and the groove wall wear is checked. The dimensions of the movable groove and the extrusion movable groove are measured with vernier calipers. If the deviation is out of tolerance, the injection mold is adjusted. The installation position of the protective shell 1 is calibrated with a laser rangefinder. The impact strength of the protective shell is tested regularly to ensure stable protective performance.

[0028] Preferably, the anti-misinsertion pressure plate 2 is inclinedly disposed inside the protective shell 1, the anti-misinsertion pressure plate 2 is located below the interface indicator plate 4, the movable end of the anti-misinsertion pressure plate 2 is provided with a positioning slot 9, and the top end of the anti-misinsertion pressure plate 2 is provided with a locking slot for engaging the push plate 3.

[0029] Specifically, the anti-misinsertion pressure plate 2 (made of silicone rubber) is installed at an angle inside the protective shell 1, below the interface indicator plate 4. The movable end has a slot 9 for engaging with the guide block 43, and the top has a locking groove for engaging and fixing with the push plate 3. The high elasticity of the silicone rubber material ensures that the connector can quickly reset after being pulled out. The angle allows the pressure when the connector is inserted to be efficiently converted into lateral thrust. The slot 9 engages with the guide block 43 to position the interface indicator plate 4 after it pops out, preventing the indicator plate from shaking and affecting observation. The locking groove engages and fixes with the push plate 3 to ensure the stability of force transmission and prevent the push plate from falling off during insertion and removal. The angled setting makes the anti-misinsertion pressure plate 2 also have a buffering effect, reducing the impact when the connector is inserted.

[0030] Based on the principle of elastic deformation, the anti-misinsertion pressure plate 2 undergoes tilting deformation when squeezed by the connector. The deformation force is transmitted to the push plate 3 through the clamping groove. The locking principle of the groove 9 is based on mechanical interlocking. After the guide block 43 is embedded in the groove, it restricts the pressure plate's reset, ensuring that the indicator plate remains in the popped-out state. The elastic recovery principle of silicone rubber allows the pressure plate to return to its initial tilted position through its own elasticity after the connector is pulled out, causing the indicator plate to be retracted. When the connector is inserted, pressure is applied along the tilted surface of the anti-misinsertion pressure plate 2, causing the pressure plate to deform and push the push plate 3 through the clamping groove. When the indicator plate pops out to its maximum stroke, the guide block 43 is inserted into the slot 9, fixing the deformation state of the pressure plate. After the connector is pulled out, the indicator plate is manually pushed to drive the guide block 43 out of the slot 9. The pressure plate resets under its own elasticity. The elastic recovery rate of the pressure plate is tested periodically, and the wear of the slot 9 is checked. The elastic recovery force of the anti-misinsertion pressure plate 2 is tested by a tensile testing machine. If it is insufficient, the silicone rubber formula is adjusted. The size of the slot 9 is inspected by a microscope to ensure the engagement gap with the guide block 43. The tilt angle of the pressure plate is calibrated by an angle gauge.

[0031] Preferably, the push plate 3 includes a compression plate 31 made of elastic material and a smooth guide wheel 32 for guiding. The compression plate 31 is engaged inside the anti-misinsertion pressure plate 2. The top end of the compression plate 31 is rotatably connected to the smooth guide wheel 32 that fits into the protective shell 1. The end of the compression plate 31 away from the anti-misinsertion pressure plate 2 is fitted with the interface indicator plate 4.

[0032] Specifically, the extrusion plate 31 (polyurethane elastic material) of the push plate 3 is engaged in the clamping groove of the anti-misinsertion pressure plate 2, and the top end is rotatably connected to the smooth guide wheel 32 (nylon material), which is in contact with the movable groove wall of the protective shell 1. The end of the extrusion plate 31 away from the anti-misinsertion pressure plate 2 is in contact with the interface indicator plate 4. The polyurethane extrusion plate 31 has both elasticity and rigidity, which can buffer the pushing force of the anti-misinsertion pressure plate 2 and avoid structural damage caused by rigid contact. The smooth guide wheel 32 converts the sliding friction between the extrusion plate 31 and the protective shell 1 into rolling friction, reducing the resistance of the indicator plate popping out and retracting. The snap-fit ​​connection ensures that the push plate 3 and the anti-misinsertion pressure plate 2 move synchronously and there is no deviation during the force transmission process.

[0033] Based on the principle of friction optimization, the rolling friction principle of the smooth guide wheel 32 reduces motion resistance, and the elastic buffer principle of the polyurethane extrusion plate 31 absorbs the thrust impact, avoiding structural deformation caused by excessive local pressure. The snap-fit ​​connection is based on the principle of mechanical fixation, ensuring that the deformation force of the anti-misinsertion pressure plate 2 is efficiently transmitted to the interface indicator plate 4, realizing the linkage of "squeezing-thrust transmission-indicator plate popping out". When the anti-misinsertion pressure plate 2 deforms, it drives the extrusion plate 31 to move through the snap-fit ​​groove, and the smooth guide wheel 32 rolls along the movable groove wall of the protective shell 1 to reduce movement resistance. The extrusion plate 31 pushes the interface indicator plate 4 to pop out, maintaining a close fit during the popping process to avoid interruption of force transmission. When the indicator plate is reset, the extrusion plate 31 moves with the indicator plate, and the smooth guide wheel 32 rolls in the opposite direction to assist in the reset. The surface of the smooth guide wheel 32 is cleaned regularly, and the wear of the extrusion plate 31 is checked. The friction coefficient of the smooth guide wheel 32 is tested by a friction tester. If the coefficient is out of tolerance, the guide wheel is cleaned or replaced. The snap-fit ​​strength of the extrusion plate 31 is verified by tensile test. If it is insufficient, the size of the snap-fit ​​groove is adjusted. The action response time of the push plate 3 is tested regularly to ensure smooth linkage.

[0034] Preferably, the interface indicator piece 4 includes a tension spring 41 providing tension, an information piece 42 marking interface information, and a guide block 43 for guiding and positioning. The tension spring 41 is fixedly installed inside the protective shell 1. One end of the tension spring 41 is fixedly installed with the guide block 43 that moves inside the protective shell 1. The middle part of the guide block 43 near the end of the tension spring 41 is fixedly connected to the guide block 43 that moves inside the protective shell 1. One end of the guide block 43 is provided with a protrusion that engages with the slot 9. During the process of the information piece 42 being squeezed out, the anti-misinsertion pressure piece 2 is deformed horizontally by the joint. During its movement, the information chip 42 drives the guide block 43 to engage with the anti-misinsertion pressure plate 2 inside the slot 9. When no indication is needed, the information chip 42 is pushed to cause the guide block 43 to release the anti-misinsertion pressure plate 2, so that the information chip 42 is reset under the action of the tension spring 41, and the anti-misinsertion pressure plate 2 is reset under its own elasticity. The top of the end of the information chip 42 away from the tension spring 41 has an information groove for writing interface information. The bottom of the information groove has several light-transmitting holes. Below the light-transmitting holes is a lighting groove for installing LED beads 5. One end of the lighting groove is fixed with a disassembly piece by screws.

[0035] Specifically, the tension spring 41 (made of piano wire) of the interface indicator piece 4 is fixed inside the protective shell 1, and the guide block 43 is fixed to one end of the tension spring and can slide along the guide groove of the protective shell 1. One end is provided with a boss to fit the slot 9. The information piece 42 (made of transparent PC) has an information groove on the top of the end away from the tension spring to engrave the interface information, a light-transmitting hole at the bottom, and an illumination groove below. One end is fixed with a screw to the disassembly piece. The tension spring 41 provides a reset pull to ensure that the interface indicator piece 4 automatically resets after popping out. The boss and the slot 9 engage to position the indicator piece and prevent it from shaking after popping out. The information groove of the transparent PC information piece 42 clearly displays the interface type. The light-transmitting hole, together with the LED beads 5, provides illumination in dim environments. The disassembly piece facilitates the maintenance and replacement of the LED beads 5. The overall structure combines the visualization of interface information with the positioning to prevent misinsertion, thus improving the accuracy of insertion and removal.

[0036] Based on the principle of elastic reset, the deformation of the tension spring 41 generates a restoring force, driving the interface indicator 4 to be housed. The positioning principle of the guide block 43 is based on mechanical engagement. After the boss is embedded in the slot 9, it restricts the movement of the indicator. The illumination principle of the information piece is based on optical conduction. The light from the LED beads 5 shines evenly into the information slot through the light-transmitting hole, enhancing the information recognition. The high light transmittance and wear resistance of the PC material ensure that the information is clearly visible after long-term use. When the push plate 3 pushes the information piece 42 to pop out, the tension spring 41 is stretched, and the guide block 43 slides along the guide groove. When it pops out to its maximum stroke... The boss of the guide block 43 is embedded into the slot 9 of the anti-misinsertion pressure plate 2 to fix the information piece. After observing the information slot to confirm that the interface is correct, continue to insert the connector to complete the connection. After pulling out the connector, push the information piece 42 to make the boss disengage from the slot 9. The tension spring 41 contracts and drives the information piece to reset. Clean the surface of the information piece regularly and check the elasticity of the tension spring. Test the tension of the tension spring 41 with a tension gauge. Replace the spring if it exceeds the tolerance. The sliding clearance of the guide block 43 is tested with a plug gauge. If it exceeds the tolerance, repair the guide groove. The light transmittance of the information piece 42 is tested with a light transmittance meter to ensure the lighting effect.

[0037] Preferably, the LED beads 5 are fixedly installed in the lighting slot inside the information sheet 42, the proximity switch 6 is fixedly installed at the top of the information sheet 42, the proximity switch 6 is located on the outside of the information slot near the tension spring 41, and the sensing metal sheet 7 is fixedly installed at the top of the movable slot inside the protective shell 1 on the side away from the tension spring 41.

[0038] Specifically, the LED bead 5 (surface mount type) is fixed in the lighting slot of the information chip 42, the proximity switch 6 (Hall effect type, connected to the microelectronic chip signal) is fixed at the top of the information chip 42, located on the outside of the information slot near the tension spring 41, and the sensing metal piece 7 (stainless steel material) is fixed at the top of the movable slot of the protective shell 1 on the side away from the tension spring 41, and the distance between it and the proximity switch 6 is adjustable. The LED bead 5 provides directional lighting, accurately illuminating the information slot, which is convenient for identifying the interface in dim environments. The Hall effect proximity switch 6 controls the switching of the LED bead 5 by the change in distance from the sensing metal piece 7, realizing lighting automation. The stainless steel sensing metal piece 7 is corrosion resistant, ensuring the detection stability of the proximity switch 6. The microelectronic chip realizes signal processing and power supply control, avoiding energy waste caused by the LED bead being constantly lit.

[0039] Based on the Hall effect principle, when the proximity switch 6 moves away from the sensing metal plate 7, it outputs a low-level signal, and the microelectronic chip controls the LED bead 5 to turn off. After the indicator plate pops out, when the proximity switch 6 moves closer to the sensing metal plate 7, it outputs a high-level signal, and the LED bead 5 turns on. The LED bead's lighting principle is based on semiconductor light emission; its low-power design reduces energy consumption, and its directional beam angle improves lighting efficiency. The overall circuit's control principle is based on automatic switching via distance sensing, requiring no manual intervention. When the interface indicator plate 4 is retracted, the distance between the proximity switch 6 and the sensing metal plate 7 increases, the LED bead 5 turns off, and the indicator... When the indicator sheet pops out, it moves the proximity switch 6 closer to the sensing metal sheet 7, reducing the distance. The LED bead 5 turns on, illuminating the information slot. After the indicator sheet resets, the proximity switch 6 moves away from the sensing metal sheet 7, and the LED bead 5 turns off. The brightness of the LED bead is tested periodically, the detection distance of the proximity switch 6 is calibrated, the surface of the sensing metal sheet 7 is cleaned, the power supply voltage of the LED bead 5 is tested with a multimeter, and the microelectronic chip is adjusted if it exceeds the tolerance. The response time of the proximity switch 6 is tested with an oscilloscope, and the switch is replaced if it exceeds the tolerance. The installation position of the sensing metal sheet 7 is calibrated with a laser rangefinder to ensure accurate detection distance.

[0040] Preferably, the stop ring 8 is located at the end of the protective shell 1 on the side where it is inserted into the information equipment interface. The cross-section of the stop ring 8 is set as a tapered structure, with the tapered end of the stop ring 8 facing the inside of the protective shell 1 and the size of the tapered end face being smaller than the size of the inner wall of the protective shell 1.

[0041] Specifically, the stop ring 8 (made of silicone rubber) is fixed to the end of the protective shell 1 on the side where it is inserted into the interface of the information equipment. The conical end face faces the inside of the protective shell, and the size of the conical end face is smaller than the inner wall size of the protective shell 1. The elasticity of the silicone rubber material allows the stop ring 8 to deform as the connector is inserted. When the interface is not confirmed, the conical structure provides pre-tightening resistance to prevent the connector from being fully inserted. After confirming that the interface is correct, increasing the insertion force can deform the stop ring, allowing the connector to be fully inserted. The guiding effect of the conical end face guides the connector to accurately align with the interface, while the sealing performance prevents dust from entering the interface. The elastic material buffers the impact when the connector is inserted, protecting the interface pins.

[0042] Based on the principle of elastic blocking, the conical structure of the stop ring 8 generates resistance through deformation. When the interface is not confirmed, it prevents the connector from penetrating deeper. After confirmation, a larger external force is applied to deform the stop ring, releasing the insertion channel. The sealing principle is based on elastic deformation, with the stop ring tightly fitting against the connector surface to fill the gap. The buffering principle is based on the elasticity of silicone rubber, absorbing the kinetic energy during insertion and reducing mechanical damage to the connector pins. When the connector is inserted, it first contacts the conical end face of the stop ring 8 and is subject to pre-tightening resistance, allowing it to be inserted only halfway into the interface. After confirming the correctness by observing the interface indicator 4, a larger insertion force is applied to deform the stop ring 8, allowing the connector to continue insertion and complete the connection. When the connector is pulled out, the stop ring 8 resets under its own elasticity. The recovery rate of the stop ring is checked periodically, and it is replaced when the wear exceeds the threshold. The surface of the stop ring is cleaned, and the pre-tightening resistance of the stop ring 8 is tested with a tension gauge. If the resistance exceeds the tolerance, the hardness of the stop ring is adjusted. The dimensions of the conical end face are measured with calipers to ensure the dimensional difference with the inner wall of the protective shell. The fatigue resistance of the stop ring is tested periodically.

[0043] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0044] When in use, and when the device is not in use, the protective shell 1 is fixed inside the interface of the information equipment with screws. The interface indicator 4 is housed in the movable groove of the protective shell under the action of the tension spring 41. The anti-misinsertion pressure plate 2 is tilted and placed in the compression movable groove. The compression plate 31 of the push plate 3 is engaged with the clamping groove of the anti-misinsertion pressure plate. The LED bead 5 is in the off state due to the distance between the proximity switch 6 and the sensing metal plate 7. The stop protective ring 8 maintains a conical structure to prevent the connector from being over-inserted. When the connector is inserted, the anti-misinsertion pressure plate 2 is first compressed along the inside of the protective shell 1, causing it to deform along the compression movable groove. The clamping groove pushes the push plate 3, and the compression plate 31 drives the smooth guide wheel 32 to roll along the protective shell wall, pushing the interface indicator 4 out of the movable groove. At the same time... When the interface indicator 4 moves, the proximity switch 6 approaches the sensing metal plate 7. The microelectronic chip controls the LED bead 5 to turn on, and the light shines through the light-transmitting hole of the information plate 42 to illuminate the information slot, allowing the operator to confirm the interface type. At this time, the connector is limited by the pre-tightening resistance of the stop ring 8 and is only partially inserted. After confirming that the interface is correct, a greater insertion force is applied to deform the stop ring 8, allowing the connector to be fully inserted. When the interface indicator 4 pops out, the guide block 43 is embedded in the slot 9 of the anti-misinsertion pressure plate 2 for positioning. After the connector is pulled out, the interface indicator 4 is pushed to make the guide block disengage from the slot, and the tension spring pulls the indicator 4 to reset. The proximity switch 6 moves away from the sensing metal plate 7 and turns off the LED bead. All structures work together to complete the anti-misinsertion protection and indication.

[0045] In summary, this information technology equipment interface mis-insertion protection device uses screws to fix a protective shell 1 inside the interface of the information technology equipment, forming an interface connection protection ring inside the interface. During the interface connection process, the connector is inserted into the interface and first enters the interior of the protective shell 1, pressing the anti-mis-insertion pressure plate 2 until it touches the stop protection ring 8. The anti-mis-insertion pressure plate 2 is then pushed by the push plate 3 to push the interface indicator plate 4 out of the protective shell 1. The interface information on the interface indicator plate 4 clearly identifies the interface, thus preventing the connector from being fully inserted into the interface by the stop protection ring 8. The interface information indicates whether the interface is connected correctly. If it is correct, the connection force is increased to deform the stop protection ring 8 and complete the connection. If the connection is incorrect, the connector can be pulled out.

[0046] This information technology equipment interface mis-insertion protection device has an LED bead 5 inside the interface indicator piece 4 to illuminate the interface information and a proximity switch 6 to control its on / off state. Based on the positional relationship between the proximity switch 6 and the sensing metal piece 7, the LED bead 5 turns on to illuminate when the interface indicator piece 4 is extruded for identification, and turns off when it is stored inside the protective shell 1 and does not indicate anything. This extends the service life, facilitates the identification of interface information in dim environments, and improves the stability of the mis-insertion protection device.
