[0006] As a further improvement of the technical solution, a rubber gasket is provided on the fixing sleeve at the position of the plug post close to the fixing post, and the rubber gasket is used to connect the post and the rubber gasket to increase the sealing performance.

[0007] As a further improvement of the technical solution, the plug post is inserted into the connection slot, and the metal rod is inserted into the connection hole.

[0008] As a further improvement of the technical solution, the inner wall of the fixed circular shell is provided with a first thread, and the first thread on the inner wall of the fixed circular shell is consistent with the second thread on the outer side of the connecting column.

[0009] As a further improvement of the technical solution, the inner wall of the fixed circular shell extends inward near the fixed column, and the portion extending from the fixed circular shell is movably installed in the slide groove.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the signal line plug-in interface, the metal at the plug-in point can be isolated from the air by the rubber gasket, and the fixed round shell in the slide groove is threadedly connected to the connecting post. When the fixed round shell is rotated, the rubber gasket on one side of the fixed post is driven to squeeze the connecting post, thereby isolating the plug-in point from the air and achieving the effect of preventing the metal surface from being corroded.

[0023] The connector 2 includes a connecting post 21, and a connecting groove 23 is formed at one side of the connecting post 21. A plurality of metal rods 24 are fixedly installed in the connecting groove 23. The plug-in post 14 is inserted into the connecting groove 23, and the metal rod 24 is inserted into the connecting hole 15. The plug-in post 14 and the connecting groove 23 and the metal rod 24 and the connecting hole 15 can be inserted more firmly. A rubber gasket 18 is fixedly sleeved at a position of the plug-in post 14 near the fixed post 11.
