Description

Technical Field

[0001] This invention relates to the field of aviation cable testing technology, and more specifically, to a testing system and method for aviation cables. Background Technology

[0002] In related technologies, the inspection of aircraft connector cables is generally carried out manually using a multimeter and a ruler. Specifically, the multimeter needs to be plugged into each cable of the connector sequentially to check for correct soldering sequence and the presence of any loose or missing welds. The length of each cable needs to be measured with a ruler to ensure it is within acceptable limits. This method is cumbersome, time-consuming, and inefficient. Furthermore, checking each cable individually with a multimeter only allows for one cable to be tested at a time, making it impossible to simultaneously check for short circuits with other cables. Additionally, manual inspection requires referring to inspection tables to determine the connection relationships between cables for each type of aircraft connector, which is time-consuming and labor-intensive when there are many connector models. Summary of the Invention

Those skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods shown in the invention can be employed without departing from the principles of the invention.

[0058] An embodiment of the present invention describes a detection system for aviation connector cables, such as... Figure 1 and 3 As shown, the system includes:

[0059] The main housing 1 is used to install the test-tested aviation plug 3 and the docking aviation plug 4. The test-tested aviation plug 3 is installed on the top of the main housing 1, and the docking aviation plug 4 is installed inside the main housing 1.

[0060] A lifting control system is installed inside the main housing 1 and is used to drive the test probe 3 to move up and down in the vertical direction so that the test probe 3 can dock or separate from the docking probe 4.

[0061] An electrical testing system is used to make the core of the cable of the test connector 3 come into contact with the testing area after the test connector 3 is connected to the docking connector 4, and to test the cable of the test connector 3 through an electrical testing path.

[0062] The display and output system is connected to the electrical testing system and the lifting control system through the communication control unit. The display and output system is used to determine whether the test connector 3 and the docking connector 4 have completed docking or separation based on the signal output by the lifting control system. It is also used to determine the test result of the cable of the test connector 3 based on the test data output by the electrical testing system and output it to the display 5.

[0063] Display 5, mounted on the upright plate 2, is used to display the detection results in real time.

[0064] The system of this invention is designed with an electrical testing system. The core of the cable of the aircraft connector 3 under test is in contact with the detection area of ​​the electrical testing system. The electrical inspection path of the electrical testing system is connected, allowing sequential testing of each cable of the aircraft connector 3 under test through the electrical inspection path, and outputting the test data to the display and output system. The display and output system has a pre-written result generation program, which calculates the test results based on the test data and stores the test results in the inspection database of the display and output system. The test results include, for example, the welding status of the cable (e.g., correct welding, poor welding, or missing welding, etc.) and the length status (e.g., length within a reasonable range, length above a reasonable range, or length below a reasonable range, etc.). The display and output system also has a display driver device for driving the display 5. The display and output system is connected to the display 5 through a screen display interface, allowing the test results calculated by the display and output system to be output to the display 5 for display. It is understood that the display and output system of this invention is located outside the upright plate 2 and the main housing 1, and can be, for example, a computer device.

[0065] The system automatically detects each cable of the aircraft connector 3 under test. When there are many cables in the aircraft connector 3 under test, the detection steps can be significantly reduced, detection time can be saved, and detection efficiency can be greatly improved. In addition, when detecting each cable, it can simultaneously check whether there is a short circuit between the cable and other cables, which can better detect each cable of the aircraft connector 3 under test and improve the accuracy of the detection results.

[0066] Understandably, there can be multiple models of the aircraft connector 3 under test, and each model of aircraft connector 3 requires a matching aircraft connector 4 to achieve the mating of the two. The connection relationships between the various cables of each model of aircraft connector 3 under test have been pre-written into the result generation program, enabling the system to test multiple models of aircraft connector cables, saving time and effort in the testing process.

[0067] It should be noted that before testing, the docking connector 4 is already installed inside the main housing 1. When testing is required, the connector to be tested 3 is installed on top of the main housing 1. The lifting control system moves the connector to be tested 3 vertically downwards from the top of the main housing 1, thereby docking the connector to be tested 3 with the docking connector 4, and testing can begin. After testing is completed, the lifting control system moves the connector to be tested 3 vertically upwards, thereby separating the connector to be tested 3 from the docking connector 4, allowing the connector to be tested 3 to be removed from the main housing 1 for testing the next connector to be tested 3. The lifting control system makes the docking and removal process of the connector to be tested 3 time-saving and labor-saving, and will not damage the connector to be tested 3 or the docking connector 4. The output signal of the lifting control system is sent to the display and output system through the communication control unit. The display and output system can then determine whether the connector to be tested 3 and the docking connector 4 have completed docking or separation based on the result generation program.

[0068] In one optional implementation, the lifting control system includes: a lifting platform 6, a left motor and a lifting rod, a motor balance driver, a right motor and a lifting rod, and power supply equipment.

[0069] The docking probe 4 is located below the lifting platform 6, and the probe to be tested 3 is located above the lifting platform 6.

[0070] The power supply equipment is used to supply power to the motor balance driver, which is used to drive the left motor and the lifting rod and the right motor and the lifting rod to move up and down in the vertical direction at the same time, thereby driving the lifting platform 6 to move up and down in the vertical direction so that the test docking plug 3 and the docking docking plug 4 can be docked or separated.

[0071] like Figure 2As shown, the power supply equipment is a high-power power supply equipment that can provide 48V power to the motor balance drive. The motor balance drive provides 48V power to the left motor and the lifting rod motor, as well as the right motor and the lifting rod. The interface (RS485) signal (this signal is a digital signal) of the motor balance drive is sent to the communication control unit. The communication control unit sends the interface (RS232) signal (this signal is a digital signal) to the display and output system. The display and output system can then determine whether the lifting control system has completed the docking or separation of the test docking connector 3 and the docking connector 4 based on the received signal.

[0072] It is understood that the motor balance driver drives the left motor and the lifting rod motor, as well as the right motor and the lifting rod, to rotate at the same speed but in opposite directions. The left motor and the lifting rod, as well as the right motor and the lifting rod, move the lifting platform 6 vertically upwards or downwards at the same speed. By driving the left motor and the lifting rod motor, as well as the right motor and the lifting rod, through the motor balance driver, the lifting platform 6 can be smoothly moved up and down, thereby achieving accurate docking and separation of the test docking module 3 and the docking module 4.

[0073] In one optional implementation, the left motor and the lifting rod, as well as the right motor and the lifting rod, employ the same lifting mechanism, which includes:

[0074] The motor 7 and the connecting arm shaft 8 are connected at one end to the output shaft of the motor 7. The connecting arm shaft 8 moves axially upward or downward under the drive of the motor 7.

[0075] The top rod assembly is connected at one end to the other end of the connecting arm shaft 8 and at the other end to the lifting platform 6. The top rod assembly moves up or down under the drive of the connecting arm shaft 8 and drives the lifting platform 6 to move up or down, so that the test aircraft plug 3 and the docking aircraft plug 4 are separated or docked.

[0076] The bearing assembly is disposed adjacent to the push rod assembly and can move in the vertical direction, thereby causing the push rod assembly to move in the vertical direction.

[0077] This invention employs the same lifting mechanism for both the left motor and the lifting rod motor, as well as for the right motor and the lifting rod, ensuring smooth movement for both. Figure 4As shown, during testing, the test module 3 and the docking module 4 need to be docked. Motor 7 is started, driving the connecting arm shaft 8 to move downwards in an arc along the axial direction. The movement of the connecting arm shaft 8 causes the push rod assembly to move downwards in a similar arc. The push rod assembly then moves the lifting platform 6 downwards, and the test module 3 moves downwards along with the lifting platform 6, thus achieving docking between the test module 3 and the docking module 4. After testing, the test module 3 and the docking module 4 need to be separated. Motor 7 is started, driving the connecting arm shaft 8 to move upwards in an arc along the axial direction. The movement of the connecting arm shaft 8 causes the push rod assembly to move upwards in a similar arc, and the push rod assembly moves the lifting platform 6 upwards. The test module 3 moves upwards along with the lifting platform 6, thus pulling the test module 3 out of the docking module 4, achieving separation between the test module 3 and the docking module 4.

[0078] The connecting arm shaft 8 has a through hole at each end. One through hole is used to connect to the output shaft of the motor 7, and the other through hole is used to connect to the push rod assembly. The connecting arm shaft 8 can be designed as two rings of different sizes, integrally formed, with the larger ring serving as one end of the connecting arm shaft 8 and the smaller ring as the other end. After one end of the connecting arm shaft 8 is connected to the output shaft of the motor 7, that end is locked by a limiting ring to restrict the rotation of the connecting arm shaft 8.

[0079] The push rod assembly includes two arc-shaped rods symmetrically arranged on both sides of the motor 7, a first push rod 11, and a second push rod 12. One end of the first push rod 11 passes through one end of the first arc-shaped rod 9, and the other end of the first push rod 11 passes through the bracket at the bottom of the lifting platform 6 and one end of the second arc-shaped rod 10. One end of the second push rod 12 passes through the other end of the first arc-shaped rod 9 and the other end of the connecting arm shaft 8, and the other end of the second push rod 12 passes through the other end of the second arc-shaped rod 10. Both ends of the first push rod 11 and the second push rod 12 are exposed at one end of the two arc-shaped rods, respectively. Limiting rings are provided at the exposed ends of the first push rod 11 and the second push rod 12 to limit their rotation.

[0080] The bearing assembly controls the vertical movement of the lifting mechanism. The bearing assembly includes a vertical linear shaft 13, a linear bearing 14 mounted on the linear shaft 13, and a bearing seat 15 that matches the linear bearing 14. The linear shaft 13 is vertically positioned inside the main housing 1. The linear bearing 14 is mounted on the outside of the linear shaft 13, and the bearing seat 15 is also mounted on the linear bearing 14. The bearing seat 15 serves as a fixing element for the linear bearing 14, and the top of the bearing seat 15 is fixed to the lifting platform 6. When the linear shaft 13 moves upward vertically, the bearing assembly moves vertically upward along with it, without any movement in other directions. Conversely, when the linear shaft 13 moves downward vertically, the bearing assembly moves vertically downward along with it, without any movement in other directions.

[0081] In one optional implementation, the electrical testing system includes: a testing area, a test acquisition board, a level signal generation and acquisition device, and a communication interface module.

[0082] The detection area is used to contact the core of the cable of the connector 3 under test. The detection area includes a test metal strip 16 located on the surface of the upright plate 2 and an external test port 17 located on the main housing 1. The external test port 17 is provided with a metal contact area, so that the external test port 17 and the test metal strip 16 are electrically interconnected.

[0083] The acquisition and testing board, the level signal generation and acquisition device, and the communication interface module are housed inside the main enclosure 1. The level signal generation and acquisition device is connected to the communication control unit via the communication interface module.

[0084] The level signal acquisition device sends an IO signal to the acquisition test board. The acquisition test board generates a level signal, which passes through the test metal strip 16 and the external test port 17 in sequence, and then sends it to the level signal acquisition device and outputs it to the display and output system, so that the display and output system can determine the current cable test result based on the output level signal.

[0085] like Figure 2 As shown, the level signal generation and acquisition device sends an IO signal. The acquisition test board generates a 5V level signal based on the received IO signal and sends it to the test metal strip 16. Since the test metal strip 16 and the external test port 17 are electrically interconnected through a metal connecting wire, the 5V level signal can be sent to the level signal generation and acquisition device through the external test port 17. The test metal strip 16, the external test port 17, the acquisition test board, and the level signal generation and acquisition device can form a connected electrical test path.

[0086] Understandably, when the level signal acquisition device receives the 5V level signal, it indicates that the electrical test path is connected, and the testing of the cable of the connector 3 under test can begin. Conversely, if the level signal acquisition device does not receive the 5V level signal, it indicates that the electrical test path is not connected, and the system malfunctions and cannot be detected. This allows for timely understanding of the equipment status and troubleshooting. Furthermore, the electrical test path design reduces wiring and related cabling, for example, reducing the connection lines between the test metal strip 16 and the level signal acquisition device, and reducing the connection lines between the external test port 17 and the acquisition test board.

[0087] The level signal generation and acquisition device sends the interface (RS485) signal (which is a digital signal) to the communication interface module. The communication interface module sends the interface (RS485) signal (which is a digital signal) to the communication control unit. The communication control unit sends the interface (RS232) signal (which is a digital signal) to the display and output system. The display and output system can then determine the cable detection result based on the received signal.

[0088] It is understood that the present invention sets up a testing area in the electrical testing system, including a test metal strip 16 located on the surface of the upright plate 2 and an external test port 17 located on the main housing 1. After straightening each cable of the aircraft plug 3 to be tested as much as possible, the cable core is brought into contact with the test metal strip 16 for testing, and the test result of the cable can be displayed on the display 5. Since the cable is straightened during the testing process, the length of the cable can be determined by the contact position of the cable core on the test metal strip 16. The cable length calculation is completed by the built-in result generation program. Accordingly, by contacting the core of each cable of the aircraft plug 3 to be tested with the test metal strip 16 for measurement, the cable test of one aircraft plug 3 to be tested can be completed.

[0089] However, the exposed end of the cable core of the cable under test 3 may be too small, making it impossible to contact the test metal strip 16 and thus preventing cable testing. In this case, the cable can be inserted into the external test port 17, and the end of the cable can be pierced to expose the core. At the same time, the exposed core makes contact with the metal contact area built into the external test port 17. After contact, the test result can be displayed on the display 5.

[0090] During testing, the contact method between the current cable core and the testing area can be determined based on the current cable core exposure status: when the current cable core exposure is large, the current cable core is brought into contact with the test metal strip 16; when the current cable core exposure is small, the current cable is inserted into the external test port 17, so that the end of the current cable is pierced to expose the core and make contact with the metal contact area built into the external test port 17.

[0091] In one optional embodiment, the system further includes an aircraft insert locking device, which comprises a first locking device and a second locking device.

[0092] The first locking device is installed on the upper part of the main housing 1 and is used to loosen or clamp the test insert 3.

[0093] The second locking device is installed inside the main housing 1 and is used to loosen or clamp the docking connector 4.

[0094] This invention designs separate locking devices for the test docking plug 3 and the docking docking plug 4, enabling separate locking of the two plugs to better complete the docking and separation processes. The first locking device clamps the test docking plug 3 during testing; after testing, it is released to remove the plug 3. The second locking device clamps the docking docking plug 4 during testing; after testing, if a different type of docking docking plug 4 needs to be replaced, it is released.

[0095] In one optional embodiment, the first locking device includes:

[0096] Pull ring 18 and pull ring arm 19, wherein the pull ring 18 is fixed to the top of the main housing 1 (i.e., fixed to the top of the lifting platform 6), and the pull ring arm 19 extends from one side of the pull ring 18;

[0097] One end of the spring 20 is fixed to the top of the main housing 1, and the other end of the spring 20 is fixed to the other side of the pull ring 18.

[0098] Multiple clamping components are provided and connected to the inner wall of the pull ring 18. The multiple clamping components can open or close simultaneously to loosen or clamp the test insert 3. The multiple clamping components close under the rebound force of the spring 20.

[0099] like Figure 3 and 4 As shown, in the initial state, spring 20 is in a naturally extended state. When testing is required, pulling the ring arm 19 causes the ring 18 to rotate. The rotation of the ring 18 causes multiple clamping components to open, and at the same time, one end of spring 20 fixed to the ring 18 is stretched. At this time, the aircraft plug 3 to be tested can be clamped in the multiple clamping components and fixed to the top of the main housing 1. Releasing the ring arm 19 causes the stretched spring 20 to rotate the ring 18 in the opposite direction. The rotation of the ring 18 causes the clamping components to close, and the multiple clamping components clamp the aircraft plug 3 to be tested. After the test is completed, the ring arm 19 can be pulled again to rotate the ring 18. The rotation of the ring 18 causes the multiple clamping components to open, and the aircraft plug 3 to be tested can then be removed from the top of the main housing 1.

[0100] The clamping assembly includes a first clamping arm 21 and a second clamping arm 22. The first clamping arm 21 is designed with a slight arc to achieve arc-shaped movement. The first clamping arm 21 is rotatably connected to the pull ring 18. The second clamping arm 22 is designed in a swallow-like shape. The middle part of the second clamping arm 22 is rotatably connected to the first clamping arm 21. One end of the second clamping arm 22 is a fixed end, used for rotatable connection to the top of the lifting platform 6. The other end of the second clamping arm 22 is a movable end, used for opening and closing actions. Multiple clamping assemblies are evenly arranged on the inner wall of the pull ring 18. When the pull ring arm 19 is pulled, the pulling force drives the pull ring 18 to rotate. The rotation of the pull ring 18 causes the first clamping arm 21 to move in a parabolic arc. The movement of the first clamping arm 21 causes the second clamping arm 22 to move in a parabolic arc, causing the movable end of the second clamping arm 22 to open. Correspondingly, when the pull ring arm 19 is released, the rebound force of the spring 20 causes the pull ring 18 to rotate in the opposite direction. The rotation of the pull ring 18 causes the first clamping arm 21 to move in a parabolic arc. The movement of the first clamping arm 21 causes the second clamping arm 22 to move in a parabolic arc, so that the movable end of the second clamping arm 22 is closed.
