[0026] The connecting cable is inserted and fixed in the insertion tube 2, and the insertion tube 2 is clamped by the clamping structure 4, and a force is always applied to it toward the insulating sleeve 1, and the first sealing pad 5 and the second sealing pad 6 are cooperated to keep it in close fit, so as to more effectively prevent dust and moisture from entering the insulating sleeve 1 from both sides and ensure its normal use.
[0027] In another embodiment, see Figures 1 to 3 The clamping structure 4 includes a longitudinally arranged plug-in rod 41, which passes through the insulating sleeve 1 and extends to the plug-in port 12. The outer wall of the plug-in tube 2 is provided with a matching plug-in hole 21 at the bottom of the plug-in rod 41. The bottom of the plug-in rod 41 is provided with an inclined surface inclined inward from left to right at the plug-in hole 21. The insulating sleeve 1 is provided with an active cavity 13 corresponding to the portion of the plug-in rod 41 located in the insulating sleeve 1. A first spring 42 is inserted at one end of the plug-in rod 41 located in the active cavity 13. A stop block 43 is fixedly provided at one side of one end of the plug-in rod 41 located in the active cavity 13 near the bottom end, and the first spring 42 abuts against the stop block 43.
[0028] When the insertion tube 2 is inserted, the abutting inclined surface can compress the first spring 42 under the cooperation of the limit block 43 to abut and lift the insertion rod 41, so as to facilitate the insertion of the insertion tube 2 into the insulating sleeve 1;
[0029] In this embodiment, the insulating sleeve 1 is horizontally provided with limiting slide grooves 14 on the upper and lower sides of the corresponding active cavity 13, and limiting sliders 44 are slidably provided in the two limiting slide grooves 14. The insertion rod 41 passes through the limiting slider 44 and is slidably connected thereto. The left ends of the two limiting sliders 44 are respectively provided with second springs 45, and the second springs 45 are respectively arranged in the corresponding limiting slide grooves 14.

[0031] Working principle: The utility model provides a radio frequency coaxial connector with a dustproof structure. When connecting, the connecting cable is passed through the insertion tube 2 and fixed, and then the annular push block 3 is held to insert the insertion tube 2 into the insertion port 12 of the insulating sleeve 1 until the connecting cable is abutted and connected with the conductor 11. In this process, when the insertion tube 2 is inserted, it abuts against the inclined surface of the insertion rod 41, thereby compressing the first spring 42 until the insertion rod 41 contracts, so that the insertion tube 2 can be smoothly inserted into the insulating sleeve 1, and then the first pull block 48 of the connecting rod 47 is manually pulled to compress the second spring 45 to the bottom of the insertion rod 41 and insert it into the insertion hole 21 for clamping, and the first pull block 48 is released. Under the action of the second spring 45, a continuous inward thrust is given to the insertion tube 2, thereby ensuring that the first sealing pad 5 and the second sealing pad 6 are tightly fitted. The operation is simple and more effective to prevent dust and moisture from entering the insulating sleeve 1 from both sides, ensuring its normal use.
[0032] During disassembly, it is only necessary to pull the second pull block 49 to make the bottom of the insertion rod 41 escape from the insertion hole 21, and move it to the right under the action of the second spring 45, so as to easily take out the insertion cylinder 2, which is convenient and quick.
