Description

Technical Field

[0001] This application relates to the field of electronic measurement technology, and in particular to a device for detecting the resistance value of an aviation socket. Background Technology

[0002] Testing the resistance value of an aviation socket refers to checking that the resistance between the connected terminals is <1Ω, and the insulation resistance between each terminal phase and to the housing is ≥20MΩ. Resistance testing is generally performed in two situations: first, a re-inspection of the resistance between the connected terminals after the socket is purchased; and second, a final inspection of the socket after assembly. The purpose is to ensure that the socket maintains continuity with the plug terminals both before and after assembly.

[0003] Due to the unique internal structure of aviation sockets, some terminals are shorted by a shorting mechanism. Resistance testing of these shorted terminals is impossible when the socket is not plugged in. A plug must be crimped into the socket to open the internal shorting mechanism before resistance testing can be performed. When crimping the plug into the socket, because the internal shorting mechanism is a spring structure, at least 300N of force is required to overcome the spring force and the friction between the pins and the socket core to press the plug and socket together. After fully crimping, because the friction between the pins and the socket core exceeds the spring force, a force of 100N is required to separate the plug and socket.

[0004] In traditional testing, the operator first needs to fix the plug, then use pliers to crimp the plug and socket together. Next, a multimeter is connected to the terminals of both the aviation plug and socket for measurement, followed by measurements of the terminals between the plug and socket. Because the terminals to be tested are located in the recesses of the plug and socket, the operator needs to carefully check both sides of the wiring terminals after each connection to ensure correct wiring. For example, an 82-pin aviation socket requires a total of 3731 measurements. After testing, the operator then uses tools or manually to separate the plug and socket. The disadvantages of traditional testing are high labor intensity for operators, low testing efficiency, and the risk of errors and omissions. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application provides a device for detecting the resistance value of an aviation socket, which solves the problem in related technologies that it is laborious to manually press and remove the plug and socket when measuring the resistance value of an aviation socket, and the measurement efficiency is low.

[0034] See Figures 1 to 4 As shown in the figure, this application embodiment provides a device for detecting the resistance value of an aviation socket, including a fixing device 1. The fixing device 1 includes a surrounding plate 3 and a mounting platform 7 disposed on the top of the surrounding plate 3. The mounting platform 7 is used to fix the aviation plug 23. A plurality of locking members 5 are disposed on the outer wall of the surrounding plate 3. The locking members 5 are used to connect or separate the aviation socket 31 from the aviation plug 23.

[0035] In use, the mounting platform 7 of the fixing device 1 fixes the aviation plug 23. Multiple locking parts 5 are provided on the outer wall of the enclosure 3 of the fixing device 1. Using the locking parts 5, the aviation socket 31 and the aviation plug 23 can be connected or separated quickly and effortlessly. When measuring the resistance value of the aviation socket 31, it is necessary to crimp and separate the aviation socket 31 and the aviation plug 23. This process is time-consuming and laborious when done by hand. Using the locking parts 5, the aviation socket 31 and the aviation plug 23 can be connected and separated more quickly and effortlessly, which is convenient for measurement and can improve measurement efficiency.

[0036] When testing the circuit resistance, one probe of a multimeter 32 is connected to the terminal to be tested on the aviation socket 31, and the other probe is in contact with the screw 22 on the test box 2 to obtain the circuit resistance measurement value. When testing the insulation resistance, the multimeter 32 is used to test the insulation resistance between the terminals and to the shell on the corresponding terminals of the test box 2. The test is convenient, improves the test efficiency, and helps to avoid errors in the test.

[0037] In some alternative embodiments, see Figures 2 to 6 As shown, this application embodiment provides a device for detecting the resistance value of an aviation socket. The locking member 5 is a manual clamp, including a quick-clamp handle 27 and a zigzag hook 28 connected to the quick-clamp handle 27. A positioning pin 8 is sleeved on the top of the hook 28, which can pass through a through hole opened in the bottom plate of the aviation socket 31 to position the locking member 5. A fastener nut 30 is provided on the manual clamp to lock the manual clamp.

[0038] In practical use, the enclosure 3 has an octagonal prism structure, with the hooks 28 and the four corners of the base plate of the aviation socket 31 located on the same vertical plane. A mounting base 9 is welded to the side wall of the enclosure 3, and the manual clamp is fixed to the mounting base 9 by the first screw 12. A first spring washer 14 and a first flat washer 16 are provided between the mounting base 9 and the manual clamp.

[0039] Specifically, such as Figure 2 As shown, four locking parts 5 manual clamps can be installed. Two of the manual clamps have locating pins 8 fitted onto the tips of their hooks 28. When connecting the aviation plug 23 and the aviation socket 31, the tips of the hooks 28 can be placed on the upper surface of the base plate of the aviation socket 31, and the locating pins 8 can be passed through the through holes in the base plate of the aviation socket 31 to position the manual clamps. Figure 6 As shown, pressing down the quick-clamp handle 27 on the manual clamp allows for relatively effortless pressing of the aviation socket 31 to connect with the aviation plug 23. At this time, the aviation plug 23 is secured by the fixing device 1, ensuring uninterrupted connection between the aviation socket 31 and the aviation plug 23.

[0040] When it is necessary to separate the aviation socket 31 from the aviation plug 23, the hooks 28 of the other two manual clamps can be placed on the lower surface of the base plate of the aviation socket 31, and then the quick clamp handle 27 on the manual clamps can be lifted up with less effort, so that the aviation socket 31 and the aviation plug 23 can be separated.

[0041] In some alternative embodiments, see Figures 2 to 6As shown, this application embodiment provides a device for detecting the resistance value of an aviation socket. The bottom of the fixing device 1 is connected to a placement platform 4 that partially protrudes from the ground. A detection cable assembly 10 is disposed inside the mounting platform 7. One end of the detection cable assembly 10 passes through the bottom of the placement platform 4 and the internal cavity of the fixing device 1 in sequence and is connected to the aviation plug 23. The other end of the detection cable assembly 10 is connected to the detection box 2.

[0042] The testing box 2 includes a box body 17 and multiple sockets 18 fixed around the box body 17, and multiple screws 22 are fixedly installed on the panel surface of the box body 17. The testing cable assembly 10 includes multiple cables 26, each cable 26 is connected to a plug 24, and the plug 24 can be connected to the socket 18.

[0043] The test cable assembly 10 is fixed to the mounting platform 7 by the second screw 11, and a second spring washer 13 and a second flat washer 15 are provided between the second screw 11 and the mounting platform 7.

[0044] In practical use, see Figure 1 As shown, after the aviation socket 31 and aviation plug 23 are connected in place, plug 24 of cable 26 is plugged into the corresponding socket 18 on the test box 2. Use multimeter 32 to connect the terminals of aviation socket 31 to the corresponding screws 22 on the test box 2. The value obtained at this time can represent the resistance value when aviation plug 23 and aviation socket 31 are connected. Similarly, a megohmmeter can also be used to complete the test.

[0045] When testing the circuit resistance, connect one probe of a multimeter 32 to the terminal to be tested on the aviation socket 31, and contact the other probe with the screw 22 on the test box 2 to obtain the circuit resistance measurement value. When testing the insulation resistance, use a multimeter 32 to test the insulation resistance between the terminals and to the shell on the corresponding terminals of the test box 2. The test is convenient, improves the test efficiency, and helps to avoid errors in the test.

[0046] After the test is completed, place the hook 28 of the manual clamp on the lower surface of the base plate of the aviation socket 31, and then lift the quick clamp handle 27 on the manual clamp. This will allow you to lift the aviation socket 31 upwards with relatively little effort, thus separating the aviation socket 31 from the aviation plug 23.

[0047] In practical use, for example, when using an 82-pin aviation socket 31, these 82 pins can be numbered A11-A23, B1-B23, C1-C23, and D1-D23 respectively. A11-A23 are connected to pins 1-13 of the 14-pin plug 24 (pin 14 is left unconnected), while B1-B23, C1-C23, and D1-D23 are connected to pins 1-23 of the three 32-pin plugs 24 respectively.

[0048] The testing box 2 has four 14-pin sockets 18 and fourteen 32-pin sockets 18 installed around its perimeter (the 14-pin and 32-pin sockets 18 are of different models), numbered sequentially from XS1 to XS18. In addition, the panel of the testing box 2 has 368 screws 22 evenly distributed, numbered vertically in 16 columns (AaBbCcDdEeFfGgHh), with each row numbered 1-23. During testing, the 14-pin plug 24 connects to socket XS2 18 on the testing box 2, and the three 32-pin plugs 24 25 connect to sockets XS3, XS4, and XS5 on the testing box 2, respectively.

[0049] The 368 screws 22 on the panel of the test box 2 are numbered so that each test screw 22 has a fixed and unique number. The connection relationship between the wiring core inside the socket 18XS1-XS18 and the corresponding numbered screws 22 is given in sequence.

[0050] For example, XS1 corresponds to 14-pin socket 18. Pins 1-10 on socket 18 are connected to screws 22 numbered A1-A10 on test box 2, and the same applies to XS2-XS18.
