Description

Technical Field

[0001] The utility model relates to a measuring tool, in particular to an insulation measuring tool for a control section of an underwater vehicle, which is mainly used for insulation measurement before debugging of the underwater vehicle and belongs to the technical field of auxiliary tools for installation, adjustment and detection of underwater vehicles. Background Art

[0002] Generally speaking, during the installation and testing of an underwater navigation body, it is necessary to use a multimeter to perform insulation testing on the inner core wire pin of the cable plug of a pressure component of a control section of the product before the test. Since the measuring plug of the control section is on the inside of the control section and the pins inside the plug are thin, and there is no dedicated measuring connector, the testing process is cumbersome and slow. The testing principle is as follows: Figure 1 At present, there are mainly the following problems:

[0003] On the one hand, it is difficult to connect the measuring plug. When measuring the insulation of the control section, the measuring plug is inside the control section and the inner space is limited so the plug position cannot be directly seen. In order to measure the accurate value, a simple jack is usually welded on the multimeter probe. When measuring, the welded simple jack needs to be accurately inserted into the measuring pin of the control section to perform insulation measurement;

[0004] On the other hand, the measurement reliability is poor. When the jack is used to assist in measuring the control section, due to the long-term wear of the jack and the easy breakage of the welding point between the jack and the multimeter probe, there will be poor contact with the measuring pin, and the measured value will be inaccurate when measuring the control section, resulting in multiple measurements to determine whether the insulation of the control section meets the requirements;

[0005] Another problem is that the measuring efficiency is low. The existing measuring aid is only a socket welded on the multimeter probe. Since the pins inside the control section measuring plug are thin, two people are required to complete the measuring work. In addition, each measurement requires the simple socket to be inserted into the 1-25 cores of the measuring plug in sequence to complete the insulation measurement work. The working efficiency is low. In short, it is often very inconvenient.

[0006] Therefore, the key to solving the above technical problems is to develop an underwater vehicle control section insulation measurement tool that is convenient to measure and has accurate measurement values. Summary of the invention
