Description

TECHNICAL FIELD

[0001] The utility model belongs to computer hardware protection technical field, concretely is a durable type stable protection device for computer interface. BACKGROUND

[0002] In the design and application of computer interface protection device, durability and stability are one of the important indicators to measure its performance. At present, some interface protection devices based on mechanical fixation or single electronic protection have appeared in the market, but these devices often fail to fully meet the actual needs when facing complex working conditions. For example, although some devices can provide a certain degree of dustproof effect or connection stability, they are prone to wear and tear during long-term high-frequency plugging, thereby affecting the durability of the interface. In addition, these devices also have limitations in electrical protection capability and are difficult to effectively respond to sudden electrical faults.

[0003] For example, the "intelligent computer power interface protection device" disclosed in Chinese invention patent (publication number: CN112397939B) has a T-shaped slider, a fixed cylinder and a convex dustproof plate. The T-shaped slider cooperates with the fixed cylinder to fix the power line connector, and the convex dustproof plate is used to prevent dust from entering the interface. This application improves the dustproof and connection stability through mechanical fixation. However, the above-mentioned patent can be used as evidence of the defects existing in the prior art, which mainly relies on mechanical structure and is prone to wear and tear in long-term high-frequency use, and does not fully consider the electrical protection capability under abnormal current or voltage.

[0004] For another example, the "dustproof and easy-to-fix joint interface protection device for computer host" disclosed in Chinese invention patent (publication number: CN109116935B) has a cooling fan, a filter screen and a fixing mechanism. The cooling fan and filter screen are used to reduce dust accumulation and improve heat dissipation effect, and the fixing mechanism is used to physically fix the interface. This application realizes the dustproof and heat dissipation function through physical shielding. However, the above-mentioned patent can be used as evidence of the defects existing in the prior art, which fails to completely solve the corrosion problem in humid environment and lacks dynamic monitoring and protection mechanism for interface loosening or accidental falling off.

[0005] Therefore, we improve it and propose a durable and stable computer interface protection device. UTILITY MODEL CONTENTS

[0029] The multifunctional protection assembly 3 is distributed on the periphery of the interface, which includes a dustproof mechanism 7, an anticorrosion mechanism 8 and a heat dissipation mechanism 9. The dustproof mechanism 7 includes a baffle 14 and a micro motor 15, the baffle 14 is connected with the front end of the outer frame body 19 through a hinge, and the micro motor 15 drives the opening and closing action of the baffle 14 through a gear transmission mechanism. The micro motor 15 is fixed on the inner wall of the outer frame body 19 through a screw, and the output shaft is engaged with the rack on the baffle 14 through a gear, so that the automatic opening and closing of the baffle 14 is realized. The inner side of the baffle 14 is also provided with a magnetic attraction switch, which is fixed on the inner surface of the baffle 14 by adhesive method, and is used for detecting the opening and closing state of the baffle 14. The signal output end of the magnetic attraction switch is connected with the control unit 13 through a wire, when the baffle 14 is opened or closed, the magnetic attraction switch sends a signal to the control unit 13, and the control unit 13 adjusts the working mode of the interface according to the state of the baffle 14. The anticorrosion mechanism 8 includes a sealing ring 16, which is sleeved on the periphery of the interface and is fixed on the inner wall of the outer frame body 19 through a buckle. The sealing ring 16 is made of silica gel material, and the surface is coated with a nano coating, which has hydrophobicity and corrosion resistance, and can effectively block the invasion of water and corrosive gas. The inner diameter of the sealing ring 16 matches the outer diameter of the interface, and the elastic deformation of the buckle realizes the close fit.

When the interface encounters sudden electrical failure, the overvoltage protection circuit 10 and the overcurrent protection circuit 11 can quickly respond and cut off the power supply, so as to ensure the safe operation of the interface and the equipment.

[0031] In addition, the multifunctional protection assembly 3 further comprises a humidity sensor fixed on the inner wall of the outer frame body 19 by screws for detecting the humidity change around the interface. The signal output end of the humidity sensor is connected with the control unit 13 through wires, and the control unit 13 adjusts the working mode of the anti-corrosion mechanism 8 according to the humidity data.

At the same time, the sealing ring 16 in the anti-corrosion mechanism 8 protects the interface in all directions, avoiding corrosion problems in humid environments. The heat-conducting sheet 17 and the micro fan 18 in the heat dissipation mechanism 9 work together to quickly dissipate the heat generated by the interface through heat-conducting silicone grease and air guide channels. When the interface encounters sudden electrical failure, the overvoltage protection circuit 10 and the overcurrent protection circuit 11 in the electrical protection unit 4 respond quickly and cut off the power supply, ensuring the safe operation of the interface and the equipment.

[0033] In actual application scenarios, the device is suitable for industrial computer interfaces that are frequently plugged and unplugged or interface equipment that is long-term exposed to harsh environments. For example, on an industrial production line, the interface needs to be frequently plugged and unplugged and may be exposed to high humidity or corrosive gas environments. The device can effectively improve the durability and stability of the interface, prolong its service life, and reduce maintenance costs. In order to better enable relevant personnel in the technical field to fully understand and implement the present utility model, the following supplementary explanation of the specific implementation principle of the present utility model is made in conjunction with a specific application scenario.

[0034] On an industrial production line, the computer interface needs to be frequently plugged and unplugged and may be exposed to high humidity or corrosive gas environments. At this time, the device can effectively improve the durability and stability of the interface, prolong its service life, and reduce maintenance costs through the cooperative work of its core functional modules. The following detailed description of the specific operation process is made in conjunction with the drawings and part numbers.

[0035] Firstly, during the process of inserting the interface plug, the displacement sensor 5, which is fixed on the inner wall of the outer frame 19 by bolts, starts to detect the insertion depth of the plug and transmits the collected data to the control unit 13 in real time. At the same time, the pressure sensor 6, which is connected to the contact surface of the outer frame 19 through an elastic gasket, senses the fixing pressure of the plug and transmits the data to the control unit 13. The control unit 13 analyzes and processes the two sets of data to determine whether the plug has reached the standard insertion state. When both the insertion depth and the fixing pressure of the plug meet the preset threshold, the control unit 13 displays the current state as "normal connection" through the LED indicator light and adjusts the working mode of the multifunctional protection assembly 3 to enter the next stage through the signal line.

[0036] Secondly, when the plug insertion is completed, the baffle 14 in the dustproof mechanism 7 is driven to close by the micro motor 15. Specifically, the micro motor 15 drives the rack of the baffle 14 through a gear transmission mechanism to achieve automatic closure of the baffle 14. The inner side of the baffle 14 is provided with a magnetic switch, which is fixed on the inner surface of the baffle 14 by adhesive for detecting the opening and closing state of the baffle 14. When the baffle 14 is completely closed, the magnetic switch sends a signal to the control unit 13, and the control unit 13 confirms that the dustproof mechanism 7 has entered the working state according to the signal to prevent dust from entering the interface internal area.

[0037] At the same time, the sealing ring 16 in the anti-corrosion mechanism 8 protects the interface in all directions. The sealing ring 16 is sleeved on the periphery of the interface and is fixed on the inner wall of the outer frame 19 by a buckle. Since the sealing ring 16 is made of silica gel material and its surface is coated with a nano coating, which has hydrophobicity and corrosion resistance, it can effectively block the invasion of moisture and corrosive gases. In addition, the humidity sensor in the multifunctional protection assembly 3 is fixed on the inner wall of the outer frame 19 by screws to detect the humidity change around the interface. When the humidity sensor detects that the surrounding environment humidity is high, the control unit 13 will adjust the working mode of the anti-corrosion mechanism 8 according to the humidity data, for example, to enhance the close-fitting degree of the sealing ring 16, to further improve the protection effect.

[0038] Then, the heat-conducting sheet 17 and the micro fan 18 in the heat dissipation mechanism 9 work together to quickly dissipate the heat generated by the interface through heat-conducting silicone grease and air guide channels. The heat-conducting sheet 17 is fixed on the bottom of the interface by screws, and its bottom surface is in contact with the metal shell of the interface through heat-conducting silicone grease, and its top surface is connected with the air guide channel of the micro fan 18. The micro fan 18 is installed on the rear end of the outer frame 19 through a bracket, and the air guide channel is connected with the interface area to form a complete heat dissipation path. The heat-conducting sheet 17 is made of graphene composite material, and its surface is provided with a microporous structure to enhance the heat conduction efficiency, thereby significantly improving the heat dissipation performance.

[0039] Finally, when the interface encounters a sudden electrical failure, the overvoltage protection circuit 10 and the overcurrent protection circuit 11 in the electrical protection unit 4 respond quickly and cut off the power supply. The overvoltage protection circuit 10 is composed of a series of voltage stabilizing diodes and current limiting resistors, with its input end connected to the power supply pin of the interface and its output end integrated through the PCB board and connected to the main control circuit of the device. The overcurrent protection circuit 11 is composed of a parallel connection of a fuse and a current detection element, and its output end is also integrated through the PCB board and connected to the main control circuit. When detecting abnormal voltage or current, the overvoltage protection circuit 10 and the overcurrent protection circuit 11 cut off the power supply through the action of the voltage stabilizing diode and the fuse respectively, ensuring the safe operation of the interface and the device.

[0040] During the entire operation described above, the high-strength aluminum alloy outer frame 19 and the inner support frame 20 of the main frame 1 provide reliable structural support. The anti-slip texture on the surface of the outer frame 19 increases the stability during operation, and the sliding grooves on both sides of the inner support frame 20 are embedded with ball bearings, reducing the friction when the module slides, thereby improving the durability of the overall device.

[0041] In summary, through the cooperative work of the dynamic monitoring module 2, the multifunctional protection assembly 3 and the electrical protection unit 4, the device realizes precise detection of the insertion state of the interface plug, comprehensive protection under complex working conditions and rapid response to sudden electrical failures, thereby meeting the high-performance requirements of interface protection devices in harsh environments such as industrial production lines.

[0042] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
