Whether they work reliably directly affects the normal operation of the aircraft circuit and involves the safety of the entire host. Electrical connectors are often connected in the form of USB to conduct electricity. USB means universal serial bus, which is mostly used for computer peripherals, such as keyboards, mice, etc. It is easier to use than traditional USB.

This patent makes the USB electrical connector more stable during installation, avoids the phenomenon of poor connection caused by looseness of the USB electrical connector, and makes data transmission more stable and accurate.

[0004] The above patent discloses a USB electrical connector, which solves the above problems. In the existing known USB 3.0 transmission conductor, the terminals Vbus and GND for providing power are too far apart to be coupled adjacently, so that Vbus is coupled with the adjacent high-frequency differential signal pair SSRX+ / SSRX-, or is coupled with the adjacent low-frequency differential signal pair D+ / D-, which easily causes the high-frequency or low-frequency differential signal to have a common mode, resulting in power supply noise, electromagnetic wave radiation, and thus electromagnetic wave interference. The high-frequency or low-frequency differential signal is therefore not coupled, resulting in high-frequency or low-frequency noise, which is also easy to cause resonance with the radio frequency signal, causing radio frequency interference, and even mixing of power supply noise and low-frequency or high-frequency noise, resulting in more difficult to solve electromagnetic wave and radio frequency interference problems.

[0061] In this embodiment, if Fig. 9As shown, the front surface of the circuit connector housing 1 is provided with an opening 2 104, and the resistance plate group 10 is arranged in the opening 2 104. The resistance plate group 10 includes a plate 1 1001, a plate 2 1002 and a plurality of straight rods 1003. A bridge plate is provided between the plate 1 1001 and the plate 2 1002. The plurality of straight rods 1003 are fixedly connected to the back of the plate 1 1001 and the plate 2 1002. The rear ends of the plurality of straight rods 1003 are all threadedly connected with the threaded rod 11. When the control module receives the leakage information sent by the resistance module, the plate 1 1001 and the plate 2 1002 in the resistance plate group 10 are controlled. 2 and the bridge plate play an electric resistance role on the connection, and the electric resistance plate group 10 is moved out of the second opening 104 under the action of the straight rod 1003, and the straight rod 1003 is threadedly connected to the threaded rod 11 at the rear end. Therefore, after the threaded rod 11 is rotated by the control module, the straight rod 1003 is controlled to move out of the second opening 104, and the surrounding of the connection is isolated to play an electric resistance role to avoid unnecessary safety hazards. The structure of the electric resistance plate group 10 is shown in the figure, and the bridge plate is located between the plate one 1001 and the plate two 1002, and the bridge plate is located on the front surface of the circuit connector housing 1.

[0062] In this embodiment, if Fig.11 As shown, the resistance module includes a control module; the control module is used for: the resistance module monitors whether there is leakage at the connection port attached by the electric detection plate, if leakage is detected nearby, the resistance module sends the leakage to the control module, and the control module detects the specific data of the leakage and the amount of electricity; the control module includes the resistance module and the main control module; the resistance module is used for: the control module controls the resistance module with the leakage data, the resistance module controls the movement of the resistance plate group 10 and the threaded rod 11, the threaded rod 11 rotates and controls the straight rod 1003 to drive the resistance plate group 10 at the front end to block electricity near the connection port; the main control module is used for: the control module transmits the leakage data and whether there is leakage to the main control module to indicate an alarm.

[0063] Working principle: Rearrange the terminals in the USB electrical connector and combine Figure 3 and Figure 4 , Fig.10As shown, the front-end conductors of the 4P terminal 6 and the 5P terminal 7 are arranged into a first high-frequency differential signal transmission conductor pair, a power supply loop transmission conductor pair, a low-frequency differential signal transmission conductor pair, and a second high-frequency differential signal transmission conductor pair, each of which is arranged in pairs by two terminals to achieve respective coupling, and through the arrangement sequence of the first high-frequency differential signal transmission conductor pair, the power supply loop transmission conductor pair, the low-frequency differential signal transmission conductor pair, the ground transmission conductor and the second high-frequency differential signal transmission conductor pair, the power supply loop transmission conductor pair is prevented from improperly coupling with the adjacent first high-frequency differential signal transmission conductor pair or the low-frequency differential signal transmission conductor pair to cause a common mode phenomenon, thereby improving the signal quality, avoiding the common mode of the radio frequency signal, and further reducing the electromagnetic interference and radio frequency interference. The 4P terminals 6 and 5P are respectively fixed on the circuit board 4 by the conductor shell 5, and the structure of the conductor shell 5 is fixed by riveting the plates and covers at the front and rear ends, which is convenient for disassembly and maintenance. When the metal sleeve 2 is inserted into the conductor In the electrical connection port, at this time, the two control buttons 8 on the front surface of the outer circuit connector shell 1 are pushed inward along the opening 103 due to the extrusion force of the plug-in, so that the control button 8 pushes the movable plate 801 backward, so that the movable plate 801 pushes the two control hooks 802 connected at the rear end to move backward, so that the control hook 802 and the hook at the upper end are moved out from the socket 904 in the rotating rod 902. Since both ends of the rotating rod 902 in the connecting rotating block 901 are connected to the spring 2 903, the rotating rod 902 can be rotated toward the connection port along the rotation direction of the spring under the action of elastic force, so that the current detection plate 9 is attached to the connection, and the connection is monitored for leakage. The resistance module monitors whether there is leakage at the connection port attached by the electric detection plate. If leakage is detected nearby, the resistance module sends the leakage to the control module, and then the control module controls the threaded rod 11 to rotate and drive the straight rod 1003 at the front end to move forward and extend. Fig. 9 As shown, the resistance plate group 10 is moved out from the second opening 104 under the action of the straight rod 1003, so that the resistance plate group 10 is attached to the periphery of the electrical connection port to block electricity, and the leakage situation is sent to the main control based on the control module to alert. If it is necessary to unplug the USB electrical connection from the interface, the front end plug-in metal sleeve 2 can be unplugged first, and then the current detection plate 9 is pressed back into the groove 102, so that the control hook 802 rebounds under the elastic force of the spring 1 803 connected to the front end of the movable plate 801, and the control hook 802 is inserted into the corresponding socket 904.

[0064] Specifically, the control module also includes:

[0065] A first real-time monitoring module is used to monitor in real time the data acquisition time when the resistance module acquires leakage data corresponding to the leakage situation;

[0066] A second real-time monitoring module is used to monitor in real time the data sending time when the resistance module sends the leakage data to the control module;

[0067] A data transmission response duration acquisition module, used to acquire the data transmission response duration by using the data acquisition time and the data transmission time;

[0068] A reference data sending response duration acquisition module is used to retrieve the data sending response duration corresponding to the last data sending when the current data sending response duration exceeds the preset first response duration threshold value as the reference data sending response duration when the data sending response duration exceeds the preset first response duration threshold value but does not exceed the preset second response duration threshold value;

[0069] The first data transmission response coefficient acquisition module is used to obtain the first data transmission response coefficient by combining the data transmission response time corresponding to each leakage data transmission of the resistance module with the reference data transmission response time, wherein the first data transmission response coefficient is obtained by the following formula:

[0070]

[0071] Among them, F x represents the first data transmission response coefficient; F max Indicates that the data transmission response time corresponding to the preset first response time threshold is exceeded, but the data transmission response time corresponding to the preset second response time threshold is not exceeded; F 01 and F 02 Respectively represent the first response time threshold and the second response time threshold; f 01 represents the first adjustment coefficient, and the first adjustment coefficient is obtained by the following formula:

[0072]

[0073] Among them, f 01 represents the first adjustment coefficient; n represents the total number of times the resistance module sends leakage data; F i Indicates the data transmission response time corresponding to the i-th leakage data transmission; F c Indicates the time it takes to send a response to the reference data; F max Indicates that the data transmission response time corresponding to the preset first response time threshold is exceeded, but the data transmission response time corresponding to the preset second response time threshold is not exceeded;

[0074] The first abnormality determination module is used to determine that the resistance module has a data transmission response abnormality and issue an abnormality alarm when the first data transmission response coefficient does not exceed a preset first coefficient threshold.

[0075] The technical effect of the above technical solution is that through the first and second real-time monitoring modules, the system can track in real time the time when the resistance module obtains leakage data (data acquisition time) and sends these data to the control module (data sending time). This real-time monitoring mechanism helps to timely discover and deal with potential problems in the data transmission process, and improves the response speed and fault detection capability of the system.

[0076] The data transmission response time acquisition module can accurately calculate the time difference from data acquisition to transmission, that is, the data transmission response time. This provides an important basis for the subsequent analysis of the status of the resistance module or data transmission link.

[0077] The reference data sending response time acquisition module and the first data sending response coefficient acquisition module work together to build a dynamic evaluation system. When the data sending response time exceeds a certain threshold but is still within an acceptable range, the system will retrieve historical data (reference data sending response time) to evaluate the current state. This mechanism enables the system to more flexibly and accurately judge the performance changes of the resistance module, rather than relying solely on a single fixed threshold.

[0078] By introducing the first data transmission response coefficient and its calculation formula, the system can intelligently evaluate the performance of the resistance module during data transmission. When the first data transmission response coefficient is lower than the preset threshold, the system can automatically determine that the resistance module has an abnormal data transmission response and trigger an abnormal alarm. This intelligent evaluation and early warning mechanism greatly improves the reliability and maintenance efficiency of the system.

[0079] Through detailed analysis and evaluation of the data transmission response time, the system can more accurately locate the source of the problem that causes data transmission delay or failure, such as the resistor module itself, the data transmission link or the control module, etc. This provides strong support for subsequent troubleshooting and repair work.

[0080] In summary, this technical solution effectively improves the reliability of data transmission of the resistance module and the overall performance of the system through real-time monitoring, dynamic adjustment, intelligent evaluation and precise positioning, providing a strong guarantee for power safety monitoring and fault warning.

[0081] Specifically, the control module also includes:

[0082] The data transmission response time calling module is used to call the data transmission response time corresponding to each leakage data transmission of the resistance module when the data transmission response time exceeds the preset second response time threshold.

[0083] The second data transmission response coefficient acquisition module is used to obtain the second data transmission response coefficient by using the data transmission response duration corresponding to each leakage data transmission of the resistance module, wherein the second data transmission response coefficient is obtained by the following formula:

[0084]

[0085] Among them, F y represents the second data transmission response coefficient; F maxy Indicates that the data transmission response time corresponding to the preset second response time threshold value exceeds; F 02 represents the second response time threshold; f 02 represents the second adjustment coefficient, and the second adjustment coefficient is obtained by the following formula:

[0086]

[0087] Among them, f 02 represents the second adjustment coefficient; n represents the total number of times the resistance module sends leakage data; F i Indicates the data transmission response time corresponding to the i-th leakage data transmission; F 01 and F 02 Respectively represent the first response time threshold and the second response time threshold; F maxy Indicates that the data sending response time corresponding to the preset second response time threshold is exceeded;

[0088] The second abnormality determination module is used to determine that the resistance module has a data transmission response abnormality and issue an abnormality alarm when the second data transmission response coefficient exceeds a preset second coefficient threshold.

[0089] The technical effect of the above technical solution is: by introducing the data transmission response time acquisition module and the second data transmission response coefficient acquisition module, when the data transmission response time exceeds the preset second response time threshold (this threshold is usually higher than the first response time threshold, indicating a more serious delay or potential problem), the system can fully retrieve the response time of each leakage data transmission of the resistance module and conduct in-depth analysis. This deep detection mechanism helps to discover those data transmission problems that occur occasionally but have a significant impact, and improves the system's fault detection capability.

[0090] The calculation of the second data transmission response coefficient takes into account the response time of multiple data transmissions of the resistance module, and introduces a second adjustment coefficient to dynamically adjust the evaluation result. This design enables the system to more accurately reflect the performance change trend of the resistance module in long-term operation, especially in the face of extreme or abnormal situations.

[0091] The second abnormality determination module makes an accurate abnormality determination based on the comparison result between the second data transmission response coefficient and the preset second coefficient threshold. When the second data transmission response coefficient exceeds the threshold, the system can immediately determine that there is an abnormal data transmission response in the resistance module and trigger an abnormality alarm. This mechanism ensures that the system can respond quickly and handle serious data transmission problems, avoiding potential safety hazards.

[0092] Through a series of measures such as real-time monitoring, in-depth detection, dynamic evaluation and precise judgment, this technical solution helps to optimize the overall stability of the system. It can not only detect and deal with problems in the data transmission process in a timely manner, but also predict and prevent potential failures through historical data analysis and performance evaluation, thereby improving the reliability and maintenance efficiency of the system.

[0093] For systems that rely on resistance modules for power safety monitoring and fault warning, this technical solution can significantly improve the user experience. By reducing data transmission delays and failure rates, the system can more accurately reflect the operating status of power equipment, provide users with more reliable and timely fault warning information, and enhance users' sense of security and trust.

[0094] In summary, this technical solution effectively improves the stability of data transmission of the resistance module and the overall performance of the system through measures such as deep fault detection, dynamic evaluation and adjustment, and precise abnormality judgment, providing more reliable technical support for power safety monitoring and fault warning.
