Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial connector, in particular to an industrial connector with voltage detection and a use method thereof. BACKGROUND

[0002] In the rapid development process of modern industrial automation and intelligent manufacturing, industrial connectors, as the core components of electrical systems to achieve stable connection and signal transmission, their performance directly determines the operation efficiency and safety of the entire industrial system. With the deepening of Industry 4.0, industrial production scenarios are becoming increasingly complex, and the integration and intelligence of equipment are constantly improving, which puts extremely strict requirements on the functionality, reliability and environmental adaptability of industrial connectors.

[0003] In terms of voltage detection function, traditional industrial connectors generally have low detection accuracy and weak anti-interference ability. Most products do not integrate professional voltage detection modules, and even if some are equipped with simple detection devices, they mostly use outdated principles such as resistance voltage division. This detection method is easily affected by factors such as environmental temperature changes and line aging, resulting in large deviations in detection results. In the complex electromagnetic environment workshop filled with high-frequency welding equipment, frequency converters and other high-power electrical equipment, the voltage detection module of the existing connector lacks effective electromagnetic shielding measures, and external electromagnetic interference can seriously distort the detection signal, making the detection data lose its actual reference value and unable to provide reliable basis for the precise control and safe and stable operation of the equipment. This not only affects the efficiency of industrial production, but also may cause equipment failure and even safety accidents, making it difficult to meet the needs of modern industry for real-time monitoring and intelligent control of electrical connections.

[0004] Defects in mechanical structure design also restrict the application of existing industrial connectors. In scenarios such as automated production lines that require frequent plugging and unplugging operations, the lack of buffering and guiding design in the plugging mechanism of the connector can cause deformation and wear of the conductive terminals during the plugging process, leading to poor contact problems. This not only reduces the accuracy of voltage detection, but also may cause electrical connection interruption, resulting in production line downtime and causing significant economic losses. For equipment working in vibrating environments such as engineering machinery and mining machinery, the existing connector anti-vibration structure is weak and cannot effectively isolate the influence of external vibration on internal electrical connections and detection modules. Long-term vibration can cause internal components to loosen, exacerbating poor contact and detection error problems. In addition, the interface size and electrical parameters of different industrial equipment differ greatly, and the existing connector has poor universality, making it difficult to quickly adapt, increasing equipment integration and maintenance costs, and limiting the flexibility and efficiency of industrial production.

[0005] The heat dissipation is also a short board of the existing industrial connector. In the high-power operation condition, the current through the conductive terminal of the connector will generate Joule heat due to the conductor resistance, and the components such as the internal voltage detection module and the signal processing module will also generate heat. However, the existing connector often lacks effective heat dissipation mechanism and cannot dissipate the internal accumulated heat in time. The high temperature will accelerate the aging of the parts and reduce the service life of the connector, and even may cause safety hazards. In summary, the existing industrial connector has many defects in voltage detection accuracy, mechanical structure rationality, heat dissipation and protection performance, which seriously restricts the efficient and safe operation of industrial production. The industrial connector with voltage detection and the use method thereof provided by the present application solve the above problems by innovative structure design, such as the cooperation of the sliding groove and the sliding block, the compression spring buffer, the efficient heat dissipation system, and the high-precision voltage detection module and signal processing module, as well as the all-around protection structure, and provide an effective solution to meet the urgent needs of modern industrial development.

[0014] An industrial connector with voltage detection and a use method thereof, comprising the following steps:

[0015] S1: In the use of the industrial connector with voltage detection, the operator first connects the plug shell with the socket shell. During the plug insertion process, the fixed frame, compression spring on the inside front and back of the plug shell work together to buffer and protect the plug conductive terminal. When the plug is subjected to insertion force, the plug conductive terminal will move towards the socket conductive terminal, at which time the compression spring connected with the plug conductive terminal is extruded. According to Hooke's law, the compression spring will generate an elastic force opposite to the direction of external force. As the insertion force increases, the compression amount of the compression spring increases, and the elastic force also increases accordingly. It converts part of the insertion force into the elastic potential energy of the compression spring, effectively reducing the damage to the plug conductive terminal caused by the plug-in impact force, avoiding its deformation or wear, and ensuring the stability and reliability of the electrical connection from the mechanical structure level. After the plug and socket are inserted into place, the power module starts to work to provide stable power supply for the voltage detection module and the signal processing module. The high-precision voltage transformer in the voltage detection module is connected with the plug conductive terminal, which monitors the voltage on the plug conductive terminal in real time. Through the principle of electromagnetic induction, high voltage is converted into low voltage, and then through the low-temperature coefficient sampling resistor, it is converted into a small voltage signal suitable for signal processing module processing, and transmitted to the signal processing module. The signal processing module processes the signal in turn. The low-noise amplifier efficiently amplifies the weak voltage signal, and at the same time of amplifying the signal, it minimizes the introduction of noise; the high-order active filter adopts a fourth-order Butterworth filter circuit, which deeply filters the interference of 20kHz and above; the high-speed analog-to-digital converter converts the filtered analog signal into a digital signal at a sampling rate of 1MSPS. The processed digital voltage data is transmitted to the external control system through the USB 3.0 data interface on the front of the plug shell at a high speed of 5Gbps. The external control system can master the electrical connection state in real time according to the received voltage data. Once the data is abnormal, such as overvoltage, undervoltage, etc., it can send out an alarm in time, and take corresponding control measures according to the preset program, such as cutting off the power supply, adjusting the equipment operating parameters, etc.

[0016] S2: In the working process of the industrial connector, when the current passes through the plug conductive terminal and the socket conductive terminal, due to the existence of resistance of the conductor, Joule heat will be generated, and the internal components such as the voltage detection module and the signal processing module will also generate heat, which will cause the temperature inside the connector to gradually rise. At this time, the first heat-conducting frame and the second heat-conducting frame play a key role in heat conduction. They are made of high-thermal-conductivity metal materials such as aluminum alloy or copper alloy, which can quickly absorb the heat generated by the plug conductive terminal, the socket conductive terminal and the internal components. The surface of the first heat-conducting frame and the second heat-conducting frame is uniformly distributed with several ventilation openings, and each ventilation opening is uniformly provided with a plurality of heat dissipation fins in a ring shape. This design greatly increases the contact area with air. When the cooling fan starts, the air flows forcibly, enters from the heat dissipation opening on the left side cover plate of the plug shell, flows through the ventilation openings and heat dissipation fins, then flows into the socket shell, and finally is discharged through the heat dissipation opening on the right side cover plate of the socket shell. During the air flow process, heat is transferred from the first heat-conducting frame and the second heat-conducting frame to the surface of the heat dissipation fins through heat conduction, and then the heat is transferred to the flowing air through heat convection. Because the heat dissipation fins greatly increase the heat dissipation area and speed up the exchange rate of heat and air, the air can quickly take away the heat. The hot air is discharged from the heat dissipation opening on the other side, forming a complete heat dissipation cycle. The temperature inside the connector is effectively reduced, avoiding the acceleration of the aging of parts due to high temperature, ensuring the stable work of the internal components such as the voltage detection module and the signal processing module in a suitable temperature environment, improving the accuracy and stability of voltage detection, prolonging the service life of the industrial connector, reducing equipment failures and maintenance costs caused by temperature problems, and having important significance for ensuring the continuity and stability of industrial production.

When the plug conductive terminal is plugged with the socket conductive terminal, the sliding block can slide smoothly in the sliding groove, effectively buffers the impact force generated in the plugging process, avoids the deformation or wear of the plug conductive terminal due to the excessive impact force, and guarantees the stability of the electrical connection from the mechanical structure level. At the same time, the setting of the first heat-conducting frame and the second heat-conducting frame, and the setting of the several ventilation openings on the surface and the heat dissipation fins inside, build an efficient heat dissipation system. In the working process of the industrial connector, the current passing through the plug conductive terminal and the socket conductive terminal will generate heat, the first heat-conducting frame and the second heat-conducting frame can quickly absorb the heat and exchange heat with the outside air through the ventilation openings, and the heat dissipation fins further increase the heat dissipation area and speed up the heat dissipation speed. The cover plates on both sides of the plug shell and the socket shell and the heat dissipation openings on the surface also provide a channel for heat dissipation, forming a complete heat dissipation cycle. This not only effectively reduces the temperature inside the connector, avoids the acceleration of the aging of the parts due to the high temperature, but also guarantees the working of the internal components such as the voltage detection module in a suitable temperature environment, improves the accuracy and stability of the voltage detection, prolongs the service life of the industrial connector, reduces the equipment failure and maintenance cost caused by temperature problems, and has important significance for guaranteeing the continuity and stability of industrial production. In addition, the voltage detection module adopts a high-precision voltage transformer and a low-temperature coefficient sampling resistor, the high magnetic permeability core material of the high-precision voltage transformer makes the transformation ratio error and phase error extremely small, and can realize high-precision isolation detection of high voltage; the low-temperature coefficient sampling resistor stably converts the secondary output voltage of the transformer, reduces the detection error caused by temperature change, and further guarantees the detection accuracy from the electrical detection level. The setting of the auxiliary conductive column increases the contact area of the plug conductive terminal and the socket conductive terminal, reduces the contact resistance, improves the reliability of the electrical connection, reduces the voltage fluctuation and detection error caused by poor contact, and further improves the overall performance of the industrial connector, the device has the advantages of ultra-high precision voltage detection, extremely stable mechanical connection and good heat dissipation effect. 2、The signal processing module and the power module integrated in the electrical box provide a solid guarantee for the voltage detection data processing and system operation of the industrial connector. The low-noise amplifier in the signal processing module can efficiently amplify the weak voltage signal output by the sampling resistor with an extremely low noise coefficient of less than 1dB, while amplifying the signal and minimizing noise introduction to ensure signal purity. The high-order active filter adopts a fourth-order Butterworth filter circuit, which has good frequency selectivity and can deeply filter the amplified signal to effectively remove the interference of 20kHz and above, further improving the signal quality.The high-speed analog-to-digital converter can quickly convert the filtered analog signal into a digital signal at a sampling rate of 1 MSPS, greatly improving the data processing efficiency. Through such a signal processing process, the industrial connector can obtain high-precision and reliable voltage data from the original signal collected by the voltage detection module through precise amplification, deep filtering and fast digital conversion. The power module provides stable power supply for the voltage detection module and the signal processing module to ensure the normal operation of each module. This integrated design avoids the connection of external signal processing equipment, reduces interference and loss in the signal transmission process, and also simplifies the system structure, improves the integration and stability of the system. In industrial production, whether it is real-time monitoring of voltage signals or providing accurate voltage data support for control systems, it can be quickly and accurately completed, effectively improving the functionality and reliability of industrial connectors in electrical connection systems, meeting the needs of modern industry for real-time monitoring and intelligent control of electrical connections.

[0029] Reference Figure 5The back surface of the inner wall of the plug shell 1 is fixedly connected with an electrical box 29, and the inside of the electrical box 29 is respectively provided with a signal processing module and a power module. The signal processing module includes a low-noise amplifier, a high-order active filter and a high-speed analog-to-digital converter. The noise coefficient of the low-noise amplifier is less than 1dB, which can efficiently amplify the weak voltage signal output by the sampling resistor.

[0030] As a technical optimization scheme of the present application, the signal processing module and the power module integrated in the electrical box 29 provide a solid guarantee for the voltage detection data processing and system operation of the industrial connector. The low-noise amplifier in the signal processing module has an extremely low noise coefficient of less than 1dB, which can efficiently amplify the weak voltage signal output by the sampling resistor, and at the same time, minimize the introduction of noise during signal amplification, ensuring the purity of the signal.

This integrated design avoids the connection of external signal processing equipment, reduces the interference and loss in the signal transmission process, and also simplifies the system structure, improves the integration and stability of the system. In industrial production, whether it is real-time monitoring of voltage signals or providing accurate voltage data support for control systems, it can be quickly and accurately completed, effectively improving the functionality and reliability of the industrial connector in the electrical connection system, meeting the needs of modern industry for real-time monitoring and intelligent control of electrical connections.

[0031] Reference Figure 1 The front surface of the plug shell 1 is provided with a data interface 30, which adopts a USB 3.0 interface standard and is electrically connected with the signal processing module, and can transmit the processed voltage data to the external control system at a transmission rate of up to 5Gbps, meeting the needs of real-time transmission of voltage data in industrial production.

[0032] As a technical optimization scheme of the present application, the USB 3.0 data interface 30 arranged on the front surface of the plug shell 1 provides a high-speed channel for the transmission of processed voltage data with its transmission rate up to 5Gbps. In the industrial production environment, the real-time requirement of the electrical system for voltage data is extremely high, and fast and accurate data transmission is the key to realize real-time monitoring and intelligent control of electrical connection. The traditional data interface 30 often has a slow transmission rate, which cannot meet the demand of fast transmission of a large amount of voltage data, resulting in data delay and affecting the timely judgment and adjustment of the control system on the state of electrical connection. However, the USB 3.0 interface standard adopted by the present application can quickly and stably transmit the digital voltage data generated by the signal processing module to the external control system. Whether in the industrial automation production line or in the complex electrical control system, the external control system can obtain the latest voltage data in a very short time in order to respond in time, such as adjusting the equipment operation parameters, issuing an alarm or taking protective measures, etc. This high-speed data transmission capability not only improves the interaction efficiency of the industrial connector and the external system, but also enhances the intelligent level and real-time control capability of the entire electrical connection system, making the industrial production process more efficient, safe and stable, effectively avoiding equipment failure and production accidents caused by data transmission delay, and providing a strong guarantee for the smooth progress of industrial production.

[0033] Reference Figure 4 The plug shell 1 and the socket shell 2 each include a base layer 14, an electromagnetic shielding layer 15 is arranged outside the base layer 14, a protective layer 16 is arranged outside the electromagnetic shielding layer 15, and an anti-skid and wear-resistant layer 17 is arranged outside the protective layer 16.

[0034] As a technical optimization scheme of the present application, the multi-layer structure design of the plug shell 1 and the socket shell 2 provides all-round protection for the industrial connector. The base layer 14 serves as the basic structure of the shell, providing the necessary mechanical strength and support to ensure the structural stability of the shell in various industrial environments and withstand certain external force impact and vibration. The electromagnetic shielding layer 15 is made of special material and can effectively shield complex external electromagnetic interference such as high-frequency electromagnetic signals and radio waves generated by high-power electrical equipment in industrial sites. If these electromagnetic interferences enter the connector, they will have a serious impact on the voltage detection signal and electrical connection, causing problems such as distorted detection data and unstable electrical connection. The presence of the electromagnetic shielding layer 15 blocks external electromagnetic interference outside the connector, ensuring the normal operation of the internal voltage detection module 28 and other electrical components, improving the accuracy and reliability of voltage detection, and the protective layer 16 further enhances the protective performance of the shell, which can resist external impact. The design of the anti-slip wear-resistant layer 17 not only allows the operator to hold the connector better when plugging and unplugging, preventing slipping and improving operational safety, but also effectively reduces the wear and tear of the shell surface during frequent use, maintaining the stability of the shell appearance and performance, and further improving the practicality and durability of the industrial connector.

[0035] Reference Figure 1 The surface of the plug shell 1 is fixedly connected with a limiting frame 18, the number of the limiting frame 18 is several, the cross section of the limiting frame 18 is L-shaped, the limiting frame 18 is attached to the socket shell 2, the front side and the rear side of the plug shell 1 are fixedly connected with a first connecting frame 19 and a second connecting frame 20 respectively, the surface of the first connecting frame 19 is fixedly connected with a guide cylinder 21, and the guide cylinder 21 is in the shape of a tapered cylinder.

[0036] As a technical optimization scheme of the present application, through the setting of the limiting frame 18, the first connecting frame 19, the second connecting frame 20 and the guide cylinder 21 and other structures, the convenience and accuracy of the industrial connector plugging operation are greatly improved. The L-shaped cross-section design of the limiting frame 18 enables it to precisely limit the plugging direction of the plug housing 1 when it is attached to the socket housing 2, avoiding the plug from deviating or tilting during insertion, ensuring that the plug conductive terminal 7 and the socket conductive terminal 8 can be accurately aligned and smoothly plugged. The first connecting frame 19 and the second connecting frame 20 are fixed on the plug housing 1 and the socket housing 2 respectively, providing stable structural support for the plugging of the connector. The conical design of the guide cylinder 21 is a highlight. During the process of plugging the plug into the socket, the conical opening of the guide cylinder 21 can be inserted into the opening of the second connecting frame 20, and the guide cylinder 21 plays a good guiding role. Even if there is a certain angle deviation during the plugging process, the guide cylinder 21 can automatically correct the plug to the correct position through its conical structure, reducing the difficulty of plugging operation and improving the operation efficiency. At the same time, this precise plugging structure design reduces the wear between the plug conductive terminal 7 and the socket conductive terminal 8, ensures the tightness and stability of electrical connection, improves the reliability of connection, reduces the problems of poor contact and voltage detection error caused by improper plugging, and makes the industrial connector still maintain good performance and longer service life in the industrial application scene of frequent plugging, providing reliable guarantee for the continuity and stability of industrial production. The operator can pass the screw through the first connecting frame 19, the second connecting frame 20 and the guide tube, then cooperate with the nut to connect the first connecting frame 19 and the second connecting frame 20, and then improve the stability of the connection between the plug housing 1 and the socket housing 2.

[0037] Reference Figure 6 The top of the plug housing 1 is fixedly connected with a mounting frame 22, and the front side and the rear side of the top of the socket housing 2 are both rotatably connected with a locking frame 23, the locking frame 23 is clamped with the mounting frame 22, the front side and the rear side of the top of the socket housing 2 are both fixedly connected with a support frame 24, the support frame 24 is rotatably connected with the locking frame 23, the top of the inner wall of the support frame 24 is fixedly connected with a torsion spring 25, the other end of the torsion spring 25 is fixedly connected with the support frame 24, and the top of the locking frame 23 is fixedly connected with a push rod.

[0038] As a technical optimization scheme of the present application, the combination of the mounting frame 22, the locking frame 23, the supporting frame 24, the torsional spring 25 and the lever realizes the functions of quick locking and convenient unlocking of the industrial connector. After the plug housing 1 and the socket housing 2 are inserted, when the operator needs to release the connection between the plug housing 1 and the socket housing 2, the lever is pulled to drive the locking frame 23 to rotate, at this time the torsional spring 25 stores energy, so that the locking frame 23 is separated from the mounting frame 22, and then the operator pulls the socket housing 2 to the right, and then the plug housing 1 and the socket housing 2 are separated. The setting of the torsional spring 25 provides stable elastic force for the locking frame 23, ensuring that the locking frame 23 can tightly fit the mounting frame 22, preventing the plug from loosening or falling off due to vibration or external force during use, and ensuring the stability and reliability of the electrical connection. This quick locking and unlocking structure is simple and convenient to operate, without the need for additional tools, greatly improving the installation and disassembly efficiency of the industrial connector. In industrial production, for scenes that need to frequently replace equipment or maintain equipment, this structure design can significantly shorten the equipment downtime and improve the production efficiency. At the same time, the stable locking structure also reduces the electrical faults and safety hazards caused by loose connection, ensuring the safe operation of industrial production, and providing strong support for the efficient and stable operation of industrial production.

[0039] Reference Figure 6 The right side of the socket housing 2 is fixedly connected with a sealing ring 27, and the sealing ring 27 is tightly fitted with the socket housing 2.

[0040] As a technical optimization scheme of the present application, the sealing ring 27 fixedly connected to the right side of the socket housing 2 provides good sealing protection performance for the industrial connector. In the industrial production environment, there are various complex factors, such as dust. Once the dust enters the connector, it will cause serious damage to the electrical connection and detection module, resulting in poor contact, short circuit, inaccurate detection data and other problems, affecting the normal operation and service life of the equipment. The sealing ring 27 is tightly fitted with the socket housing 2, and after the plug and the socket are inserted, an effective sealing barrier can be formed. The industrial connector of the present application can maintain the cleanliness of the internal electrical connection and ensure the normal operation of the voltage detection module 28 and other electrical components by the sealing effect of the sealing ring 27. This sealing design not only improves the environmental adaptability of the industrial connector, but also enhances its protection performance, prolongs the service life, reduces the cost of equipment maintenance and replacement caused by environmental factors, and provides reliable protection for the stable operation of industrial production in various complex environments. The inside of the heat dissipation hole 13 is fixedly connected with a dust screen for preventing dust from entering the plug housing 1 or the socket housing 2.

[0041] Reference Figure 1An industrial connector with voltage detection and a method of using the same, comprising the following steps:

[0042] S1: When using the industrial connector with voltage detection, the operator first connects the plug shell 1 with the socket shell 2. During the plug insertion process, the fixed frame 9 and the compression spring 10 inside the plug shell 1 cooperate to buffer and protect the plug conductive terminal 7. When the plug is subjected to an insertion force, the plug conductive terminal 7 will move towards the socket conductive terminal 8, at which time the compression spring 10 connected with the plug conductive terminal 7 is subjected to compression. According to Hooke's law, the compression spring 10 will generate an elastic force opposite to the direction of the external force. As the insertion force increases, the compression amount of the compression spring 10 increases, and the elastic force also increases accordingly, converting part of the insertion force into the elastic potential energy of the compression spring 10, effectively reducing the damage to the plug conductive terminal 7 caused by the insertion impact force, avoiding its deformation or wear, and ensuring the stability and reliability of the electrical connection from the mechanical structure level. After the plug and the socket are inserted into place, the power module starts to work to stably supply power to the voltage detection module 28 and the signal processing module. The high-precision voltage transformer primary coil in the voltage detection module 28 is connected with the plug conductive terminal 7, which monitors the voltage on the plug conductive terminal 7 in real time. Through the principle of electromagnetic induction, the high voltage is converted into low voltage, and then through the low-temperature coefficient sampling resistor, it is converted into a small voltage signal suitable for signal processing module processing, and transmitted to the signal processing module. The signal processing module processes the signal in turn. The low-noise amplifier efficiently amplifies the weak voltage signal while minimizing noise introduction; the high-order active filter adopts a fourth-order Butterworth filter circuit to deeply filter out interference above 20 kHz; the high-speed analog-to-digital converter converts the filtered analog signal into a digital signal at a sampling rate of 1 MSPS. The processed digital voltage data is transmitted to the external control system at a high speed of 5 Gbps through the USB 3.0 data interface 30 on the front of the plug shell 1. The external control system can master the electrical connection state in real time according to the received voltage data, and can issue an alarm in time and take corresponding control measures according to the preset program, such as cutting off the power supply, adjusting the equipment operating parameters, etc., once the data is abnormal, such as overvoltage, undervoltage, etc.

[0043] S2: In the working process of the industrial connector, when the current passes through the plug conductive terminal 7 and the socket conductive terminal 8, due to the resistance of the conductor, Joule heat will be generated, and the internal components such as the voltage detection module 28 and the signal processing module will also generate heat, causing the internal temperature of the connector to gradually rise. At this time, the first heat-conducting frame 3 and the second heat-conducting frame 4 play a key role in heat conduction. They are made of high-thermal-conductivity metal materials such as aluminum alloy or copper alloy, which can quickly absorb the heat generated by the plug conductive terminal 7, the socket conductive terminal 8, and the internal components. The first heat-conducting frame 3 and the second heat-conducting frame 4 are evenly distributed with several ventilation openings 5 on their surfaces, and each ventilation opening 5 is evenly provided with multiple heat dissipation fins 6 in a ring shape. This design greatly increases the contact area with air. When the heat dissipation fan 11 starts, the air flows from the left side cover 12 of the plug housing 1, enters the heat dissipation opening 13, flows through the ventilation openings 5 and the heat dissipation fins 6, and then flows into the socket housing 2. Finally, it is discharged through the heat dissipation opening 13 on the right side cover 12 of the socket housing 2. During the air flow process, heat is transferred from the first heat-conducting frame 3 and the second heat-conducting frame 4 to the surface of the heat dissipation fins 6 through heat conduction, and then the heat is transferred to the flowing air through heat convection. Because the heat dissipation fins 6 greatly increase the heat dissipation area and speed up the exchange rate of heat and air, the air can quickly take away the heat. Hot air is discharged from the other side of the heat dissipation opening 13, forming a complete heat dissipation cycle. This effectively reduces the internal temperature of the connector, avoids the accelerated aging of components due to high temperature, ensures the stable operation of the internal components such as the voltage detection module 28 and the signal processing module in a suitable temperature environment, improves the accuracy and stability of voltage detection, prolongs the service life of the industrial connector, reduces equipment failures and maintenance costs caused by temperature problems, and has important significance for ensuring the continuity and stability of industrial production.

[0044] The working principle and use process of the application: when using the industrial connector with voltage detection, the operator first connects the plug shell 1 with the socket shell 2. During the plug insertion process, the fixed frame 9 and the compression spring 10 inside the plug shell 1 cooperate to buffer and protect the plug conductive terminal 7. When the plug is subjected to an insertion force, the plug conductive terminal 7 will move towards the socket conductive terminal 8, at which time the compression spring 10 connected with the plug conductive terminal 7 is subjected to extrusion. According to Hooke's law, the compression spring 10 will generate an elastic force opposite to the direction of the external force. As the insertion force increases, the compression amount of the compression spring 10 increases, and the elastic force also increases accordingly. A part of the insertion force is converted into the elastic potential energy of the compression spring 10, effectively reducing the damage to the plug conductive terminal 7 caused by the insertion impact force, avoiding its deformation or wear, and ensuring the stability and reliability of the electrical connection from the mechanical structure level. After the plug and the socket are inserted into place, the power module starts to work, providing stable power supply for the voltage detection module 28 and the signal processing module. The high-precision voltage transformer primary coil in the voltage detection module 28 is connected with the plug conductive terminal 7, which monitors the voltage on the plug conductive terminal 7 in real time. Through the principle of electromagnetic induction, the high voltage is converted into low voltage, and then through the low-temperature coefficient sampling resistor, it is converted into a small voltage signal suitable for signal processing module processing, and transmitted to the signal processing module. The signal processing module processes the signal in turn. The low-noise amplifier efficiently amplifies the weak voltage signal, and at the same time, the noise introduction is minimized; the high-order active filter adopts a fourth-order Butterworth filter circuit, which deeply filters the interference of more than 20kHz; the high-speed analog-to-digital converter converts the filtered analog signal into a digital signal at a sampling rate of 1MSPS. The processed digital voltage data is transmitted to the external control system through the USB 3.0 data interface 30 on the front of the plug shell 1 at a high speed of 5Gbps. The external control system can master the electrical connection state in real time according to the received voltage data, and can issue an alarm in time and take corresponding control measures according to the preset program, such as cutting off the power supply, adjusting the equipment operation parameters, etc.

[0045] In the working process of the industrial connector, when the current passes through the plug conductive terminal 7 and the socket conductive terminal 8, Joule heat will be generated due to the resistance of the conductor, and heat will also be generated by the working of the internal components such as the voltage detection module 28 and the signal processing module, causing the internal temperature of the connector to gradually rise. At this time, the first heat-conducting frame 3 and the second heat-conducting frame 4 play a key role in heat conduction. They are made of high-thermal-conductivity metal materials such as aluminum alloy or copper alloy, which can quickly absorb the heat generated by the plug conductive terminal 7, the socket conductive terminal 8, and the internal components. The surface of the first heat-conducting frame 3 and the second heat-conducting frame 4 is evenly distributed with several ventilation openings 5, and each ventilation opening 5 is uniformly provided with multiple heat dissipation fins 6 in a ring shape. This design greatly increases the contact area with air. When the cooling fan 11 is started, the air flows from the cooling port 13 on the left side cover 12 of the plug housing 1, flows through the ventilation openings 5 and the heat dissipation fins 6, and then flows into the socket housing 2, and finally flows out through the cooling port 13 on the right side cover 12 of the socket housing 2. During the air flow, heat is transferred from the first heat-conducting frame 3 and the second heat-conducting frame 4 to the surface of the heat dissipation fins 6 through heat conduction, and then the heat is transferred to the flowing air through heat convection. Because the heat dissipation fins 6 greatly increase the heat dissipation area and speed up the exchange of heat and air, the air can quickly take away the heat. The hot air is discharged from the cooling port 13 on the other side, forming a complete heat dissipation cycle. This effectively reduces the internal temperature of the connector, avoids accelerated aging of parts due to high temperature, ensures the stable operation of the internal components such as the voltage detection module 28 and the signal processing module in a suitable temperature environment, improves the accuracy and stability of voltage detection, prolongs the service life of the industrial connector, reduces equipment failures and maintenance costs caused by temperature problems, and has important significance for ensuring the continuity and stability of industrial production.

[0046] The above-mentioned voltage detection module 28, signal processing module, power module, plug conductive terminal 7 and socket conductive terminal 8 are common existing technologies and are well known to those skilled in the art, and will not be described in detail.

[0047] The traditional connector only transmits current through the core contact surface of the plug conductive terminal 7 and the socket conductive terminal 8, while the addition of the auxiliary conductive column 26 expands the contact point from "single point" to "multiple points". The increase in contact area can reduce the current density and reduce local heating according to the Joule law Q=I 2 Rt. Reducing the resistance R will directly reduce the heat generation.
