[0022] like Figures 1 to 4As shown, the RF coaxial connector fixing device is used to fix the RF coaxial connector 1, including a fixing plug 3 and a columnar fixing socket 2, the fixing plug 3 includes an insulating tube body 31 sleeved on the outside of the RF coaxial connector 1, the insulating tube body 31 is fixedly connected to the RF coaxial connector 1, and a plurality of spring pieces 34 are arranged on the outside of the middle section of the insulating tube body 31, the tail end of the spring piece 34 is connected to the insulating tube body 31 as a whole, and the head end of the spring piece 34 is connected to the outer wall of the insulating tube body 31. A spacing is set between them, the angle between the length direction of the spring piece 34 and the length direction of the insulating tube body 31 is α, the length direction of the insulating tube body 31 is the direction of the central axis of the insulating tube body 31, and α is an acute angle; a plurality of convex plates 32 are set at the rear section of the insulating tube body 31, the head end of the spring piece 34 is set between the tail end of the spring piece 34 and the head end of the convex plate 32, a convex block 33 is set on the outer side of the tail end of the convex plate 32, and a spacing is set between the front end of the convex block 33 and the head end of the convex plate 32, the The protrusion 33 and the protrusion plate 32 form an L-shaped step structure; the head end of the fixed socket 2 is provided with a channel for installing the RF coaxial connector 1, and at least one channel is provided, the channel includes a first mounting hole 21 for the protrusion 33, the protrusion plate 32 and the insulating tube body 31 to enter and exit, a second mounting hole 22 for the protrusion plate 32 and the insulating tube body 31 to enter and exit, and a third mounting hole 23 adapted to the spring 34. The first mounting hole 21, the second mounting hole 22 and the third mounting hole 23 are coaxially arranged and interconnected. The tail end of the fixed socket 2 is provided with a fourth mounting hole 24, and the fourth mounting hole 24 is provided with one; if multiple channels are provided, then the multiple channels are all connected to the fourth mounting hole 24; the second mounting hole 22 is arranged between the first mounting hole 21 and the third mounting hole 23, and the third mounting hole 23 is connected to the fourth mounting hole 24. The aperture of the first mounting hole 21 is larger than the aperture of the second mounting hole 22, and the aperture of the third mounting hole 23 is larger than the aperture of the second mounting hole 22.

[0023] The RF coaxial connector 1 is a RF plug or a RF socket. In this embodiment, for the convenience of description, the RF coaxial connector 1 is selected to be a RF socket. Figure 1 As shown. The insulating tube body 31, the convex plate 32, the convex block 33 and the spring 34 are all made of insulating plastic in one piece. The fixed plug 3 is made of insulating material, which can prevent the RF coaxial connector 1 from leaking or being electrically connected to other electrical devices to affect signal transmission. The aperture of the first mounting hole 21 is equal to the aperture of the third mounting hole 23.

[0024] In this embodiment, the fixed plug 3 is fixedly connected to the RF socket. In the process of inserting the fixed plug 3 into the fixed socket 2, first, the front end of the RF socket passes through the first mounting hole 21, the second mounting hole 22, the third mounting hole 23 and the fourth mounting hole 24 in sequence. Further, the aperture of the fourth mounting hole 24 is larger than the aperture of the third mounting hole 23. The aperture of the fourth mounting hole 24 is large enough to facilitate the subsequent plugging of the RF socket and the RF plug. In the process of the front end of the RF socket passing through the first mounting hole 21, the second mounting hole 22, the third mounting hole 23 and the fourth mounting hole 24 in sequence, the spring piece 34 will also pass through the first mounting hole 21, the second mounting hole 22 and the third mounting hole 23 in sequence. In this embodiment, when the spring sheet 34 is subjected to external force, the α value is 12°, and the head end of the spring sheet 34 will not be squeezed by the hole wall of the first mounting hole 21 when passing through the first mounting hole 21; when the head end of the spring sheet 34 passes through the second mounting hole 22, the hole wall of the second mounting hole 22 will squeeze the head end of the spring sheet 34 so that the distance between the head end of the spring sheet 34 and the outer wall of the insulating tube body 31 becomes smaller, and the α value becomes smaller to 6°; finally, the spring sheet 34 will enter the interior of the third mounting hole 23, the aperture of the third mounting hole 23 is larger than the aperture of the second mounting hole 22, and the bound spring sheet 34 will open so that the head end of the spring sheet 34 is pressed against the hole wall of the third mounting hole 23, and the α value becomes 8° at this time. Further, the α value satisfies that 6°≤α≤30°, and α cannot be too large, otherwise the resistance of the spring sheet 34 when moving forward will increase sharply; α cannot be too small, otherwise the spring sheet 34 cannot generate enough elastic force to press against the hole wall of the third mounting hole 23. In addition, the plane where the second mounting hole 22 and the third mounting hole 23 meet is parallel to the front end face of the spring sheet 34, so that the front end of the spring sheet 34 also simultaneously presses against the step at the junction of the second mounting hole 22 and the third mounting hole 23. The above structure has a stop function. After the RF socket and the RF plug are connected, the RF socket and the RF plug can be effectively prevented from being separated, thereby ensuring that the RF socket and the RF plug are always in a fully connected state.

[0025] Since the aperture of the first mounting hole 21 is larger than that of the second mounting hole 22, the aperture of the third mounting hole 23 is larger than that of the second mounting hole 22; the first mounting hole 21, the second mounting hole 22 and the third mounting hole 23 are all coaxially arranged, so that a protruding structure 221 is formed at the second mounting hole 22, and the protruding structure 221 is located between the first mounting hole 21 and the third mounting hole 23; when the fixed plug 3 and the fixed socket 2 are fully inserted, the front of the protruding structure 221 is a spring 34, the rear of the protruding structure 221 is the protruding block 33, and the protruding structure 221 is just stuck between the protruding block 33 and the spring piece 34. Under the obstruction of the protruding structure 221, the protruding block 33 can no longer move forward. At the same time, the spring piece 34 will also press against the protruding structure 221. The protruding structure 221 plays a limiting role, thereby ensuring that the fixed plug 3 and the fixed socket 2 are fully plugged in, and the plugged fixed plug 3 and the fixed socket 2 are not easy to separate, and the fixed plug 3 and the fixed socket 2 are in a locked state.

[0026] Furthermore, in order to facilitate the integral molding of the protrusion 33 and the protrusion plate 32 , the rear end surface of the protrusion 33 is flush with the rear end surface of the protrusion plate 32 .

[0027] Furthermore, there are two protrusions 33, two protrusion plates 32, and two spring pieces 34. The planes where the two protrusions 33 are located are coplanar with the planes where the two protrusion plates 32 are located, and the planes where the two protrusion plates 32 are located are coplanar with the planes where the two spring pieces 34 are located. The protrusions 33, protrusion plates 32, and spring pieces 34 are all provided in two numbers, on the one hand to reduce production costs; on the other hand, the coplanar arrangement is to reduce the difficulty of plugging.

[0028] In the above embodiment, the RF coaxial connector fixing device has a simple structure and is easy to use. After the fixed plug 3 and the fixed socket 2 are plugged in, the fixed plug 3 and the fixed socket 2 are in a locked state, and the fixed plug 3 and the fixed socket 2 are not easily separated, and the plug-in quality is high; when the RF socket and the RF plug complete the plug-in operation, the RF socket and the RF plug can be effectively prevented from being separated, ensuring that the RF socket and the RF plug are always in a fully plugged state.

[0029] The inner conductor or the outer conductor in the radio frequency socket or the radio frequency plug is plugged in at the fourth mounting hole 24. This structure is conducive to the plugging action, ensures the accuracy of the plugging action, and also has a protective effect.

[0030] As for separating the fixed plug 3 and the fixed socket 2 after being plugged in, it is necessary to use a sleeve that matches the third mounting hole 23 and the spring clip 34, insert the sleeve into the third mounting hole 23 and force the spring clip 34 to converge so that the α value is reduced, and finally the spring clip 34 can pass through the second mounting hole 22 again.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
