Description

Technical Field

[0001] This application relates to the field of multi-core cable testing technology, and in particular to a multi-core cable wiring sequence testing device. Background Technology

[0002] Multi-core cables are cables with two or more cores, achieving parallel transmission through concentric twisting or group shielding. One end of a multi-core cable has a connector, and each core is connected to a corresponding pin on the connector according to wiring rules. Each core and each pin is numbered. When wiring is correct, the core number matches the pin number. However, due to the close proximity of the pins, wiring errors can occur. To prevent accidents caused by incorrect wiring, a wiring sequence test is performed on the multi-core cable before use, verifying the correctness of the core numbers.

[0003] The current wiring sequence testing process is roughly as follows: First, one person is stationed at each of the first and second ends of the cable. Second, the person at the first end connects any two wires in the cable, disconnecting all the remaining wires, and then notifies the person at the second end via walkie-talkie. Third, the person at the second end uses a test probe to test each wire one by one until they find the two connected wires (identified by the beeping sound of the test probe), marks them, and then notifies the person at the first end. Fourth, the person at the first end assigns a wire number to the remaining wire, connects it to the two previously connected wires, and then notifies the person at the second end. Fifth, the person at the second end connects one test probe to the previously connected wires and uses the other probe to test each of the remaining wires until they find the connected wire, assigns a wire number, and then notifies the person at the first end. Steps four and five are repeated until all wires have been tested. Finally, separate the two core wires that were connected first. The person at the first end connects one of them to the wire that has already been calibrated and notifies the person at the second end. The person at the second end uses a test probe to find this core wire and assigns it a core wire number.

[0004] It is evident that the above testing method requires two people to work together, the testing steps are very cumbersome, resulting in low testing efficiency. Moreover, many human factors (such as incorrect communication between the two people, incorrect observation, mishearing the beeping sound of the test instrument, etc.) can lead to incorrect test results, so the accuracy of the test results is low.

[0005] Therefore, how to improve testing efficiency and the accuracy of test results is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The measurement and control module has multiple test circuits;

[0008] A cable connector is used to mate with the end connector of the cable under test. In the mating state, each pin of the end connector of the cable under test is electrically connected to a different test circuit.

[0026] This application provides a multi-core cable wiring sequence testing device. In order to enable those skilled in the art to better understand the technical solution of this application, the flow channel element and thermal management system provided in this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3 As shown, the multi-core cable wiring sequence testing device provided in this application includes a measurement and control module, a cable connector, a test probe interface 400, and an output component.

[0028] The measurement and control module includes multiple test circuits. Additionally, it has control circuits to manage the output components. Specifically, the test and control circuits can be integrated onto a chip as integrated circuits.

[0029] The cable connector is used to mate with the end connector of the cable under test. In the mating state, each pin of the end connector of the cable under test is electrically connected to a different test circuit. Specifically, only one cable connector can be provided, or two or more different types of cable connectors can be provided to test different types of cables. For example, in the illustrated embodiment, two cable connectors are provided: the first cable connector 200 is an aviation connector, and the second cable connector 300 is a DB25 connector.

[0030] The test probe interface 400 is used to connect one end of a test probe. The other end of the test probe (hereinafter referred to as the test end) is used to sequentially contact one core wire of the cable under test to sequentially close different test circuits. In other words, during testing, one end of the test probe is inserted into the test probe interface 400, and the test end of the test probe contacts the conductive part of one core wire of the cable under test. At this time, the test probe closes the test circuit located at the pin connected to that core wire. The test probe interface 400 is compatible with multimeter probes. By setting the test probe interface 400, test probes can be flexibly replaced, avoiding situations where test probe damage leads to the scrapping of the entire testing device or delays in maintenance.

[0031] The output component communicates with the measurement and control module, specifically through any connection method capable of signal transmission, such as electrical or wireless connection. The measurement and control module is configured to control the output component to output the pin numbers of the currently closed test circuit. Specifically, the output component may include a display screen 500 and a voice announcer. The display screen 500 displays the pin numbers, and the voice announcer plays the pin numbers, allowing testers to confirm the correct numbers by both sight and sound, avoiding misjudgments due to inaccurate visual or auditory perception. Specifically, the display screen 500 can be a touchscreen. When it is a touchscreen, the measurement and control module can be configured to control the touchscreen's display settings and cable connector type options. The settings include brightness adjustment for the display screen 500, on / off adjustment for the voice announcer, and volume adjustment for the voice announcer. This allows testers to adjust the brightness of the display screen 500, the volume of the voice announcer, and the on / off state of the voice announcer according to the actual test environment. The cable connector type options on the touchscreen allow users to select and enable a cable connector compatible with the end connector of the currently tested cable.

[0032] During testing, a tester holds the test probes and touches the conductive parts of different cores of the cable under test in sequence. If the circuit connection is correct and the testing device is working properly, each test circuit will close in sequence, and the output component will output the pin numbers of the closed test circuits in sequence under the control of the measurement and control module. If there is no output, it means that there is a problem with the circuit connection or the testing device is faulty.

[0033] If the pin number output by the output component is the same as the pin number on the current core wire, it means the pin number on the current core wire is correct. If the pin number output by the output component is different from the pin number on the current core wire, it means the pin number on the core wire is incorrect. In this case, the tester can manually mark the correct pin number on the core wire. For example, if the pin number on the current core wire is 2, but the pin number output by the output component is 3, it means that the current core wire is actually core wire 3 connected to pin 3, and the pin number on the core wire needs to be corrected to 3.

[0034] As can be seen, when using the above-mentioned testing device for wire sequence testing, only one tester is required, instead of two testers working together, thus reducing personnel costs. Furthermore, the correct serial number is output through the output component, eliminating the need for the tester to visually identify the serial number from the pins, verify the serial number with another tester, or determine the circuit closure based on the beeping of the test probes. This reduces the possibility of human error and improves testing efficiency and accuracy. Moreover, the serial number can be displayed on the screen 500 and announced via voice broadcast, further ensuring the accuracy of the serial number obtained by the tester.

[0035] Specifically, in the illustrated embodiment, the multi-core cable sequence testing device includes a housing 100, which is generally rectangular. A display screen 500 is mounted on a larger area of ​​one side wall of the housing 100, while cable connectors and test probe interfaces 400 are mounted on another larger area of ​​the housing 100. This arrangement does not affect the layout of the display screen 500, allowing it to be larger for easier viewing by the tester. A speaker hole 700 is located on the smaller area of ​​the housing 100's side wall, and a voice announcer is located inside the housing 100, allowing the voice announcer's audio to be emitted from the speaker hole 700. The housing 100 integrates the entire testing device into a single, unified structure, making the testing device easier to move and use.

[0036] Specifically, in the illustrated embodiment, the multi-core cable sequence testing device also includes a battery, which serves as the power source for the testing device. The battery is housed inside the housing 100. The battery can be a rechargeable battery (e.g., a lithium battery), or a non-rechargeable battery (e.g., a dry cell battery). Alternatively, an external power interface can be provided to power the testing device from an external power source, or the external power source and the battery can complement each other.

[0037] Specifically, in the illustrated embodiment, the housing 100 is also provided with a power switch 900, a battery charging interface 700, and a power indicator light 800. The battery charging interface 700 can also serve as the aforementioned external power interface. The power indicator light 800 is used to indicate the power on / off status. Before testing, the power switch 900 is turned on, and the power indicator light 800 illuminates. After the test is completed, the power switch 900 is turned off, and the power indicator light 800 goes out.

[0038] Specifically, in the illustrated embodiment, the measurement and control module also includes a battery protection circuit. The battery protection circuit is connected between the battery charging interface 700 and the battery, and plays a role in stabilizing voltage during the charging process, which helps to extend the battery's service life.

[0039] Specifically, in the illustrated embodiment, the measurement and control module further includes a test protection circuit and a current-limiting resistor, which are connected between the power switch 900 and the test circuit. Specifically, the current-limiting resistor can be connected between the test protection circuit and the power switch 900. The current-limiting resistor and the test protection circuit respectively serve to limit current and stabilize voltage, ensuring the safety of the testing process.

[0040] The above examples illustrate the principles and implementation methods of this application. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
