However, some connectors must use a new connector due to various issues such as the use environment, appearance, shape, and technical requirements. At this time, it is very important for the user to test the electrical connection performance of the plug-in, and the first thing to test is the number of plug-in and unplugging tests.

[0003] Existing methods for testing the number of plug-in and plug-out times are generally multimeter measurement method and laboratory measurement. The multimeter method, as the name implies, uses a multimeter to measure the resistance value of the corresponding pins at both ends of the plug-in. This method is simple and fast and is suitable for plug-ins with fewer pins, but it is not practical for the CT18-82Z / T type connector of China North Industries Group Corporation with 82 pins; laboratory measurement is to use a computer and a professional plug-in and unplugging mechanism to measure in the laboratory. The electrical signal of the plug-in is converted through an IO (Input / Output) module and then input into a PC (personal computer). After being processed by special computer software, it is recorded and displayed on the screen. This method has high requirements for professional equipment and software and is not universal.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, the first embodiment of the utility model proposes a plug-in plug-in test device, including a plug 10, a socket 20, a controller 30 and an alarm circuit 40. The controller 30 is electrically connected to the plug 10, the socket 20 and the alarm circuit 40 respectively, and is used to detect the on / off state of the plug 10 and the socket 20, and control the alarm circuit 40 to perform sound and light alarm. In this embodiment, the controller 30 can be a PLC (Programmable Logic Controller) controller or a single-chip microcomputer. The plug 10 adopts a CT18-82T plug. The plug 10 is an 82-core plug. The socket 20 adopts a CT18-82Z socket. The socket 20 is an 82-core socket. The alarm circuit 40 can adopt an sound and light alarm circuit, all of which are within the protection scope of this patent.

[0026] Further, see Figures 1 to 4 The plug-in plug-in test device provided in this embodiment, the alarm circuit 40 includes a light-emitting diode and a buzzer, and the controller 30 is electrically connected to the light-emitting diode and the buzzer respectively. The multiple voltage output ports of the controller 30 are respectively connected to the positive poles of the corresponding multiple light-emitting diodes and the buzzer through wires, and the negative pole of the light-emitting diode is connected to the corresponding tail pins of the socket 20; the ground port of the controller 30 is connected to the corresponding tail pins of the plug 10. The plug-in plug-in test device also includes a power supply 50. Preferably, the power supply 50 adopts a 24V (volt) power supply. The plug-in plug-in test device provided in this embodiment is used to test the electrical connection reliability and short-circuit protection characteristics of some pins of the CT18-82Z / T type and similar connectors of the China National Aeronautics and Space Administration during multiple plug-ins. The output port with detection function on the PLC controller is used to convert the electrical connection state of the pins of the 82-core connector into sound and light modes and send them to the tester for observation and recording.

[0027] like Figures 1 to 4 As shown, the plug-in plug-in test device provided in this embodiment has the following working principle:

[0028] The plug-in and plug-out test device comprises a PLC controller 30, an 82-core plug 10, an 82-core socket 20, a light emitting diode, a buzzer and a 24V power supply.

[0029] The 24V power supply 50 supplies power to the PLC controller 30. Wires are led out from the voltage output port of the PLC controller 30 and connected to the positive poles of several light-emitting diodes and a buzzer respectively. The negative poles of the light-emitting diodes are respectively connected to the common tail pins No. 13-82 of the 82-core socket 20. Wires are led out from the corresponding tail pins of the 82-core plug 10 and connected to the ground port of the PLC controller 30. If the short-circuit protection function of the 82-core socket 20 is to be tested, a wire is led out from the voltage output port of the PLC controller 30 and connected to one end of the short-circuit pin (such as pin No. 2), and the other end (pin No. 1) is connected to the positive pole of the light-emitting diode, and then the negative pole of the light-emitting diode is connected to the ground port of the PLC controller 30.

[0030] Figure 2 and Figure 3 The figure shows the schematic diagram of the CT18-82Z / T plug-in of China North Industries Group Corporation. In the figure, the pins 1-2, 3-4, ..., 11-12 in the middle box of the socket CT18-82Z enter the on and off states as the plug-in is unplugged, and the remaining pins 13-82 are independent of each other.

[0031] In the figure, the voltage output of DO83 is related to the detection status of DO2-DO82. When the plug-in is disconnected, there is a path between pins 1-2, 2-3, ..., 11-12; L1-2, ..., L11-12 lights are on. When the plug-in is plugged in tightly and functions normally, the path between pins 1-2, 2-3, ..., 11-12 is disconnected, L1-2, ..., L11-12 are off, and DO13-DO82 outputs normally at this time, and the connected light-emitting diodes L13-L82 emit light normally; if the short-circuit protection of pins 1 and 2 of the plug-in fails, the corresponding DO2 port is detected as an open circuit state when the plug-in is disconnected, DO83 outputs an electrical signal, and the buzzer sounds; if pins 13-82 of the plug-in are in poor contact, the corresponding DO13-DO82 pins detect an open circuit state, the corresponding light-emitting diodes are off, DO83 outputs an electrical signal, and the buzzer sounds.

[0032] The plug-in plug-in test device provided in this embodiment, compared with the prior art, adopts a plug, a socket, a controller and an alarm circuit, and the controller is electrically connected to the plug, the socket and the alarm circuit respectively. This embodiment is used to test the electrical connection reliability and the short-circuit protection characteristics of some pins of the CT18-82Z / T type and similar connectors of the China Military Aviation Union during multiple plug-ins. The output port with detection function and the logic calculation ability on the PLC controller are used to convert the electrical connection state of the pins of the 82-core connector into sound and light modes and send them to the tester for the tester to observe and record. The plug-in plug-in test device provided in this embodiment can realize self-adaptation to different places and devices to be tested. The required test tools are very common and the electrical wiring is very simple; the test process is simplified. As long as the buzzer does not alarm, it can be considered that the plug-in is valid. When the buzzer alarms, the state of the light-emitting diode can be checked to quickly find the cause of failure and the corresponding pin; high-sensitivity detection of the access and disconnection states is realized, and the autonomous detection by the PLC controller takes less time, has high accuracy and fast feedback.
