Description

Technical Field

[0001] The utility model relates to the technical field of low-pressure test boxes, in particular to a data line sealing device for a low-pressure test box. Background Art

[0002] Low-pressure test chambers are mainly used in aviation, aerospace, information, electronics and other fields to determine the environmental adaptability and reliability tests of instruments, electrical products, materials, components and equipment under the single or simultaneous effects of low pressure, high temperature and low temperature. Low-pressure test chambers are widely used in laboratories. When conducting low-pressure tests, the test equipment needs to lead the data cable to the outside of the test chamber through the circular hole reserved on the side wall of the test chamber to connect with the test instrument. After the data cable is arranged, the circular hole needs to be sealed to ensure that the test chamber can be reduced to the pressure value specified for the test. The data cable sealing device is used to seal the data cable.

[0003] However, the data cable sealing of the low-pressure test box currently on the market is done manually by using rubber plugs and putty to seal the circular hole. The sealing efficiency is low and it is easy to loosen. During the low-pressure test, as the air pressure in the test box gradually decreases, the air pressure difference between the inside of the test box and the external environment will gradually increase. At this time, if the manual sealing is not strong enough, air leakage will occur, resulting in the air pressure inside the test box being unable to continue to decrease and unable to reach the air pressure value required by the test. In severe cases, the rubber plug will be suddenly sucked into the test box. The huge air pressure difference will suck objects near the circular hole into the test box, causing safety hazards. The data cable arrangement is poorly organized, which is not conducive to the safety of the data cable. The data cable sealing device is an integral structure, which is inconvenient to install the data cable and is not conducive to the convenience of use. Therefore, those skilled in the art provide a low-pressure test box data cable sealing device to solve the problems raised in the above background technology. Summary of the Invention
