DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1~Figure 5 As shown;

[0020] It comprises a shell 1, an inner conductor 2 is installed inside the shell 1, a fixing piece 3 is installed on one side of the inner conductor 2, and the inner conductor 2 is fixedly connected to the fixing piece 3;

[0021] A fixing mechanism 4 is installed inside the inner conductor 2, and the fixing mechanism 4 includes a fixing part 2 41 and a driving member 42. A rubber pad 8 is installed inside the fixing part 1 3, and the rubber pad 8 is fixedly connected to the fixing part 1 3. A sealing mechanism 9 is installed inside the fixing part 1 3, and the sealing mechanism 9 includes a moving block 91 and a moving ring 92. The driving member 42 drives the fixing part 2 41 to move, and limits the lateral and longitudinal displacements of the fixing part 1 3. While limiting the fixing part 1 3, the sealing mechanism 9 and the rubber pad 8 are squeezed to reduce the gap between the rubber pad 8 and the cable.

[0022] By moving the fixing member 3, the fixing member 3 is moved to the position of the driving member 42, and then moved again to drive the driving member 42 to move, and the driving member 42 drives the fixing member 2 41 to move, so that the fixing member 2 41 moves downward, so that the fixing member 2 41 is conveniently inserted into the inside of the fixing member 3, and when the fixing member 2 41 reaches the inside of the fixing member 3, the moving block 91 is squeezed, so that the moving block 91 moves with the moving ring 92, and the moving ring 92 is driven to squeeze the rubber pad 8, and the moving ring 92 wraps the rubber pad 8, so that the rubber pad 8 is deformed, resulting in a closer contact between the rubber pad 8 and the cable, while fixing the inner conductor 2 and the fixing member 3, the sealing between the fixing member 3 and the cable can be increased, so that the sealing effect of the device is better;

[0023] A third extension block 421 is installed on the top of the driving member 42. The third extension block 421 is slidably connected to the inside of the inner conductor 2. A second spring 6 is installed on one side of the third extension block 421.

[0024] When the driving member 42 moves, it will bring the third extension block 421 to squeeze the second spring 6. When the fixing member 3 stops squeezing the driving member 42, the driving member 42 returns to its original position due to the elasticity of the second spring 6.

[0025] A first extension block 31 is installed on the top of the fixing member 3, and a first moving groove 21 is opened inside the inner conductor 2 at a position corresponding to the first extension block 31, and the first extension block 31 slides inside the first moving groove 21;

[0026] When the fixing member 3 moves, the first extension block 31 slides inside the first moving groove 21 to increase the stability of the movement;

[0027] An extrusion groove 411 is provided inside the second fixing member 41. The cross-sectional shape of the extrusion groove 411 is a right-angle trapezoid, and the top of the driving member 42 contacts the inclined surface of the extrusion groove 411.

[0028] By moving the driving member 42, the inclined surface of the extrusion groove 411 is squeezed, and the fixing member 2 41 is driven to move, so as to facilitate the fixing of the fixing member 1 3;

[0029] A second extension block 412 is installed on one side of the second fixing member 41, a second moving groove 22 is opened inside the inner conductor 2, the second extension block 412 slides inside the second moving groove 22, and a first spring 5 is installed inside the second moving groove 22, the first spring 5 is fixed to the second extension block 412;

[0030] After the second fixing member 41 moves, the first spring 5 is squeezed, so that after the driving member 42 leaves, the second fixing member 41 returns to its original position and releases the fixation with the first fixing member 3;

[0031] A limiting rod 7 is installed inside the fixing member 1 3, a slider 71 is installed on the top of the limiting rod 7, and a slide groove 32 is installed on one side of the slider 71;

[0032] By pulling the limiting rod 7, the limiting rod 7 is moved, so that the driving member 42 can be extended into the interior of the fixing member 3, so as to release the fixing between the inner conductor 2 and the fixing member 3;

[0033] The working principle of the radio frequency connector of the present invention is as follows: by moving the fixing member 3, the fixing member 3 is moved to the position of the driving member 42, and then moved again to squeeze the driving member 42, causing the driving member 42 to move, and the driving member 42 moves to squeeze the extrusion groove 411, driving the fixing member 2 41 to move, so that the fixing member 2 41 moves downward, so that the fixing member 2 41 is stuck in the inside of the fixing member 3, and when the fixing member 2 41 reaches the inside of the fixing member 3, the moving block 91 is squeezed, so that the moving block 91 moves with the moving ring 92, driving the moving ring 92 to squeeze the rubber pad 8, and the moving ring 92 wraps the rubber pad 8, so that the rubber pad 8 is deformed, resulting in the rubber pad 8 and the rubber pad 8 being connected. The contact of the cable is closer. While fixing the inner conductor 2 and the fixing part 3, the sealing between the fixing part 3 and the cable can be increased, so that the sealing effect of the device is better. During the movement of the fixing part 41, the second extension block 412 moves with the fixing part 41. The movement process squeezes the first spring 5 to deform the first spring 5. To remove it, you only need to pull the limiting rod 7, so that the driving part 42 moves to the inside of the fixing part 3 due to the elasticity of the second spring 6 and disengages from the inside of the extrusion groove 411. The fixing part 41 returns to its original position under the elasticity of the first spring 5, which makes it easy to remove the fixing part 3 from the inside of the inner conductor 2, and disassembly is more convenient.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
