Abstract
Description
Technical Field
[0001] The utility model relates to a troubleshooting tool kit, and more specifically, mainly relates to a measuring line device used for aircraft troubleshooting. Background Art
[0002] At present, when an aircraft fails, electronic maintenance personnel need to confirm the source of the fault. They often need to use various multimeters, milliohmmeters, loop meters, megohmmeters and other equipment, and use their own probes to touch or even violently insert them into expensive aircraft computers or electrical actuators. Due to loose fixation such as virtual connections, the measured error value is large, affecting the troubleshooting efficiency. Moreover, if an inappropriate probe is inserted into the computer SOCKET (socket), it may cause the computer socket to expand, which in turn aggravates the damage to the aircraft computer components and even affects flight safety. In current practice, only special tools such as BMC (bleed air leakage tester) are usually equipped, and the scope of use is limited to troubleshooting the bleed air loop, and the tool is expensive. Therefore, it is necessary to study and improve the structure of portable troubleshooting tools with a wide coverage area for troubleshooting. Utility Model Content

And the head end of the aforementioned pin and slot line 4 is provided with a pin, and the end is provided with a slot, and the pin and the slot are matched with each other, so as to facilitate the end-to-end plug-in connection of multiple wires; the head end of the aforementioned connecting line 5 is provided with a male plug connector, and the end is provided with a female plug connector, the male plug connector is used to connect with the acquisition interface of the multimeter 3, and the female plug connector is used to connect with other connecting wires or the terminal of a computer, and the connecting wire 5 can also be connected together by connecting the head and the tail.
[0016] like Figure 2 and Figure 3As shown, the inner cavity of the box 1 is also provided with a placement slot for placing the short-circuit wire 6. The short-circuit wire 6 has two specifications, namely the first short-circuit wire 61 and the second short-circuit wire 62. The first short-circuit wire 61 has a pin at its head and a slot at its head and a slot at its head. Further, the connecting wire 5 also has two specifications, namely the first connecting wire 51 and the second connecting wire 52. The first connecting wire 51 is the same as the above, with a male plug connector at its head and a female plug connector at its end, which can be connected end to end; and the second connecting wire 52 has an alligator clip at its head and a pin or a slot at its end, which is convenient for clamping and connecting with the terminal.
