[0034] Embodiment:

[0035] As Figure 1-2 shown, this embodiment proposes a highly sealed coaxial connector, including a male connector 20, and a female connector 10 is provided on the male connector 20;

[0036] A connecting pipe 12 is provided on the female connector 10, a connecting sleeve 21 is provided on the male connector 20, an external thread wall 121 is provided on the outer wall of the connecting pipe 12, an internal thread wall 211 is provided on the inner wall of the connecting sleeve 21, the internal thread wall 211 is adapted to the external thread wall 121, a sealing sleeve 11 is provided on the outer wall of the connecting pipe 12, a connecting sealing ring 15 is provided between the inner wall of the sealing sleeve 11 and the outer wall of the connecting pipe 12, and the connecting sleeve 21 is threadedly connected to the outer wall of the connecting pipe 12, so that the connecting sleeve 21 extends into the inner cavity of the sealing sleeve 11 to squeeze the connecting sealing ring 15 for sealing.

[0037] In this embodiment, when the male connector 20 and the female connector 10 are connected, the connecting sleeve 21 on the male connector 20 is aligned with the connecting pipe 12, and then the male connector 20 is manually displaced to insert the connecting sleeve 21 into the sealing groove 14. Then, the connecting sleeve 21 is rotated through the thread fit between the internal thread wall 211 and the external thread wall 121, so that the connecting sleeve 21 is connected to the outer wall of the connecting pipe 12 until the connecting sleeve 21 contacts the connecting sealing ring 15 and squeezes the connecting sealing ring 15, thereby completing the sealing process;

[0038] By providing a connection sleeve 21 and a connection pipe 12 between the male connector 20 and the female connector 10, and respectively providing an external thread wall 121 and an internal thread wall 211 on the outer wall of the connection pipe 12 and the inner wall of the connection sleeve 21, the two can be tightly connected through thread fitting, thereby improving the connection stability and reliability of the connector. At the same time, when the connection sleeve 21 is threadedly connected to the outer wall of the connection pipe 12 and extends into the inner cavity of the sealing sleeve 11, the connection sealing ring 15 can be squeezed, achieving a high sealing effect, effectively preventing interference from the external environment (such as dust and water vapor) to signal transmission, ensuring signal stability and transmission quality. Moreover, when the connection sleeve 21 contacts the connection sealing ring 15, the outer wall of the connection sleeve 21 contacts the inner wall of the sealing sleeve 11, which can further improve the sealing performance and also protect the connection sealing ring 15, greatly improving the overall sealing performance.

[0039] Specifically, a fixed pipe 25 is provided on the male connector 20, and a fixed ring plate 27 is provided on the outer wall of the fixed pipe 25;

[0042] Of course, when the connection sleeve 21 is connected to the connection pipe 12, the contact between the barrier ring plate 22 and the fixed ring plate 27 can further improve the sealing performance.

[0043] Specifically, a barrier sleeve 222 is provided on the barrier ring plate 22;

[0044] An annular sealing and fixing groove 271 is formed on the fixed ring plate 27, and a barrier sealing ring 272 is provided in the annular sealing and fixing groove 271. The barrier sleeve 222 extends into the annular sealing and fixing groove 271 and contacts the barrier sealing ring 272 for sealing.

[0045] In this embodiment, when the barrier ring plate 22 contacts the fixed ring plate 27, the barrier sleeve 222 extends into the fixed sealing groove 14, and the barrier sleeve 222 contacts the barrier sealing ring 272 for sealing, which can further improve the sealing effect and ensure the airtightness and waterproof performance of the connection part.

[0046] Specifically, a plurality of groups of first connection holes 212 are evenly formed in the connection sleeve 21, and a plurality of groups of second connection holes 221 are evenly formed in the barrier ring plate 22. The positions of the first connection holes 212 and the second connection holes 221 are matched, and a connection bolt 23 is arranged between the first connection holes 212 and the second connection holes 221.

[0047] In this embodiment, by arranging the connection bolt 23 between the first connection holes 212 and the second connection holes 221, it is convenient to disassemble the connection sleeve 21 from the male connection head 20 for maintenance, improving the overall practicality.

[0048] Specifically, a plurality of groups of reinforcing sealing rings 213 are arranged between the barrier ring plate 22 and the connection sleeve 21.

[0049] In this embodiment, the reinforcing sealing rings 213 can improve the sealing performance between the barrier ring plate 22 and the connection sleeve 21.

[0050] Specifically, the sealing sleeve 11 is provided with a guiding inclined surface 111;

[0051] The connection sleeve 21 is provided with an annular contact surface 28, and a contact sealing ring 24 is arranged on the annular contact surface 28. The connection sleeve 21 is connected to the connection pipe 12, so that the contact sealing ring 24 extends into the guiding inclined surface 111.

[0052] In this embodiment, when the connection sleeve 21 is connected to the connection pipe 12, the contact sealing ring 24 can extend into the guiding inclined surface 111, further improving the overall airtightness.

[0053] Specifically, the barrier ring plate 22 is provided with a barrier surface 223, and a fixed sealing ring 224 is arranged on the barrier surface 223;
