It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] In train operation, the reliability of electrical connection systems is crucial, and the clamping force of the connector pin is one of the key factors affecting the stability of electrical connections. Pin clamping force failure is random and insidious; insufficient clamping force can lead to operational accidents such as abnormal door interlocking and traction system malfunctions, seriously threatening the stable operation and safety of subway trains. Current pin positioning and clamping force testing tools generally suffer from low efficiency and high safety risks. The core problem lies in the manual operation of the male pin to test the connector pin clamping force, relying entirely on intuition and making it difficult to quantify and standardize the process.

[0019] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0020] Embodiments of this application provide a device for detecting the state of a female connector pin in a rail transit vehicle.

[0021] Reference Figure 1 A female pin status detection device for rail transit vehicle connectors includes: a female pin probe 100, a detection sensor 200, a converter 300, a data transmission module 400, and a host computer 500.

[0022] The female needle probe 100 is shaped to match the female needle 600 of the connector, and is used to connect with the female needle 600. The input end of the detection sensor 200 is connected to the female needle probe 100. The detection sensor 200 is disposed inside the flexible tube and is equipped with a pin and a pressure sensor circuit. The pressure sensor circuit is used to detect the radial positive pressure value applied by the female needle 600 to the pin. The converter 300 is connected to the output end of the detection sensor 200 and is used to convert the radial positive pressure value from an analog signal to an electrical signal. The host computer 500 is connected to the converter 300 and is used to display the radial positive pressure value.

[0023] In this embodiment, the female pin probe 100 is inserted into and fixed to the female pin 600 of the connector to detect the state of the female pin 600. Since the shape of the female pin probe 100 matches the shape of the female pin 600, poor contact during testing can be avoided, preventing inaccurate detection of the state of the female pin 600. The detection sensor 200 is disposed within a flexible tube, allowing the female pin probe 100 to bend based on the sensor 200, greatly adapting to the detection of the position of the female pin 600 on the vehicle connector, demonstrating the flexibility of the detection device. The pin of the detection sensor 200 is inserted into the female pin 600 of the connector, and the radial positive pressure value applied by the female pin 600 to the pin is detected by the pressure sensor circuit. The radial positive pressure value applied by the female pin 600 to the pin is the clamping force of the female pin 600. The converter 300 converts the radial positive pressure value from an analog signal to an electrical signal. The converter 300 sends the radial positive pressure value in the form of an electrical signal to the data transmission module 400, which then transmits the radial positive pressure value to the host computer 500. The host computer 500 processes and displays the radial positive pressure value.

[0024] The female needle probe 100 has multiple through holes 610, and a detection sensor 200 is slidably connected within each through hole 610. The inner wall of each through hole 610 has a groove, and the detection sensor 200 has a protrusion that is slidably connected to the groove. The female needle probe 100 can extend and retract based on the detection sensor 200, greatly adapting to the detection of the position of the female needle 600 on the vehicle connector, demonstrating the flexibility of the detection device.

[0025] Reference Figure 2 Multiple through holes 610 are arranged in an array. For example, there are 50 through holes 610, arranged in 5 rows and 10 columns. Of course, in other embodiments, the arrangement of the multiple through holes 610 is set according to the type of the female needle 600.

[0026] It is understandable that the number of through holes 610 corresponds to the number of female needles 600, and the number of detection sensors 200 corresponds to the number of female needles 600. Each through hole 610 is equipped with one detection sensor 200.

[0027] The operating female needle probe 100 is inserted into the female needle 600 of the connector and fixed. The through hole 610 corresponds one-to-one with the position of the female needle 600. The pin of the detection sensor 200 is moved so that the pin is inserted into the female needle 600 along the through hole 610.

[0028] The host computer 500 and the converter 300 are connected via a data transmission module 400. The data transmission module 400 is an I / O input / output module and is equipped with data lines.

[0029] Reference Figure 3The host computer 500 is a PLC touch screen all-in-one machine for easy operation. The host computer 500's control interface includes buttons for multiple modes, as well as test, reset, start, and stop buttons. The start button turns the device on, the stop button turns it off, the test button initiates the test of the clamping force of the female needle 600, and the reset button allows for resetting the test parameters.

[0030] Of course, in other embodiments, the host computer 500 may include a host, an input device, and an output device. The host, input device, and output device are different devices and are connected together through a transmission line.

[0031] In this embodiment, after the operating female needle probe 100 is inserted into the female needle 600 of the connector and fixed, and the pin is inserted into the female needle 600 along the through hole 610, the operator presses the test button on the operation interface of the host computer 500. The pressure sensor circuit of the detection sensor 200 collects the radial positive pressure value applied by the female needle 600 to the pin by monitoring the pressure on the surface of the pin.

[0032] The hose is made of insulating material, such as insulating plastic.

[0033] The rated voltage of the detection sensor 200 is DC 5V, which is provided by the host computer 500.

[0034] The voltage range of the electrical signal is 0 to 5V, which ensures the recognizability and stability of the electrical signal transmitted to the data line.

[0035] This rail transit vehicle connector female pin status detection device can comprehensively and accurately test and evaluate the performance of the connector female pin 600, thereby ensuring that the radial positive pressure applied by the female pin 600 to the male pin in the connector meets the standard, avoiding equipment failures such as loose connection and poor contact of the male and female pins 600 due to insufficient clamping force. Moreover, the male pin on the male pin linear tension sensor can be replaced according to the different types and specifications of the connector female pin 600 being detected, ensuring the convenience, safety, real-time performance, accuracy, flexibility, and practicality of the connector female pin 600 status detection.

[0036] The above is a detailed description of the preferred embodiments of this application, but this application is not limited to the embodiments.
