[0035] The lower part of the vacuum extraction joint 2 is provided with an external thread 21 and is installed in the mounting hole 11 through the external thread 21. The mounting hole 11 is a stepped hole. After the vacuum extraction joint 2 is installed, the head does not protrude from the top surface of the plug 1.

[0041] The plug 1 is the key core structure of the present utility model, and its structure is as Figure 3 and Figure 4 shown. The plug 1 is fixed on the product housing by three groups of screws and gaskets.

[0042] The working principle is as follows:

[0043] When evacuating the product housing, remove the vacuum extraction joint 2, and install the vacuum extraction tube joint in the installation hole 11 to perform the operation; when detecting the cable performance of the product, remove both the plug 1 and the vacuum extraction joint 2 to perform the operation.
