[0002] RF connectors are key components used in RF transmission systems, primarily for transmitting high-frequency signals between systems, circuit elements, and subassemblies. They precisely control the conductor size and spacing in the coaxial structure to provide a low-loss, high-bandwidth signal transmission path and shield against electromagnetic interference.
[0003] During the use of RF connectors, two independent individuals are usually fixed together through a spiral connection. Although the spiral structure connection of the RF connector provides reliable electrical and mechanical connection, it also has some disadvantages. First, the spiral connection requires a certain amount of rotational force, which may result in a slower connection speed and is not conducive to quick plugging and unplugging. Second, frequent rotational connection may cause thread wear, affecting the long-term stability and reliability of the connector. In addition, the thread structure may capture dust and impurities and requires regular cleaning to avoid degradation of signal transmission performance. Finally, the spiral connection has certain requirements for alignment accuracy. Improper connection may cause signal loss or reflection, affecting the overall RF performance. Therefore, a self-locking RF connector is proposed to address the above problems. Utility Model Content

[0023] See also Figure 1-5 , the utility model provides a technical solution:
[0024] A self-locking radio frequency connector comprises a socket 1 and a plug 2, wherein the plug 2 is slidably connected to the inside of the socket 1, the plug 2 comprises a plug body 21, a limit ring 22 is fixedly connected to the outside of the plug body 21, a fixed clamping ring 23 is fixedly connected to the outside of the plug body 21, a sliding ring 24 is slidably connected to the outside of the plug body 21, a guide pin 3 is arranged on the inside of the plug body 21, a pinhole 4 is provided on the inside of the socket 1, a locking mechanism 5 is fixedly connected to the outside of the socket 1, the locking mechanism 5 comprises a fixed ring 51, a telescopic spring 52 is fixedly connected to the outside of the fixed ring 51, the other end of the telescopic spring 52 is fixedly connected to a movable ring 53, an elastic sheet 54 is fixedly connected to the outside of the movable ring 53, a block 55 is fixedly connected to the outside of the elastic sheet 54, a notch 56 is provided on the inside of the movable ring 53, and a slide rail 57 is fixedly connected to the outside of the socket 1.
[0025] As a further implementation of this solution, the sliding ring 24 is arranged between the limiting ring 22 and the fixed snap ring 23. The inclined surface of the sliding ring 24 and the inclined surface of the fixed snap ring 23 are both facing the direction of the socket 1. The inclination angle of the inclined surface of the sliding ring 24 is the same as the inclination angle of the inclined surface of the fixed snap ring 23, ensuring the same-direction guidance and positioning accuracy when the plug 2 is inserted, thereby improving the docking efficiency and accuracy.
[0026] As a further implementation of this solution, the minimum diameter of the fixing clamp 23 is the same as the maximum diameter of the plug body 21, the regular cross-section of the fixing clamp 23 is a right triangle, and the minimum radius of the fixing clamp 23 is the same as the minimum arc radius of the clamping block 55, so that a tight fit is formed between the fixing clamp 23 and the plug body 21, thereby enhancing the stability of the connection.
[0027] As a further implementation of this solution, the fixed ring 51 and the movable ring 53 have the same size. The movable ring 53 is arranged on the side of the fixed ring 51 close to the plug body 21. The movable ring 53 and the fixed ring 51 are on the same axial line. The movable ring 53 always slides on the outside of the socket 1, ensuring the smooth sliding of the movable ring 53 on the outside of the socket 1 and improving the smoothness of the operation of the locking mechanism 5.
[0028] As a further implementation of this solution, there are two slide rails 57, which are symmetrically arranged on the outside of the socket 1. The length of the slide rail 57 is the same as the shortest distance from the fixed ring 51 to the socket 1 close to the plug body 21. The movable ring 53 slides on the outside of the slide rail 57 through the two notches 56 on the inside, providing a stable sliding track for the movable ring 53, ensuring the positioning accuracy and structural symmetry of the movable ring 53.
[0029] As a further implementation of this solution, there are several elastic sheets 54 and clamping blocks 55. The elastic sheets 54 are evenly distributed on the same side of the movable ring 53. The thickness of the elastic sheet 54 is the same as the thickness of the movable ring 53 minus the maximum depth of its inner notch 56. The elastic sheet 54 is an arc-shaped sheet, which provides a balanced elastic force and clamping effect. The arc-shaped elastic sheet 54 helps to improve the tightness and stability of the clamping.
[0030] As a further implementation of this solution, the shortest length of the inclined surface of the block 55 is twice the shortest length of the inclined surface of the sliding ring 24. The block 55 and the fixed clamping ring 23 are engaged with each other, and the side cross-section of the block 55 is a right triangle, which enhances the engagement strength and stability between the block 55 and the fixed clamping ring 23 and improves the reliability of the connection.
[0031] Working process: When using the RF connector, the plug body 21 can be inserted into the inner side of the socket 1, and the guide pin 3 on the inner side of the plug body 21 is gradually inserted into the pinhole 4 of the socket 1. At the same time, the elastic piece 54 fixedly connected to the movable ring 53 on the outer side of the socket 1 gradually covers the outer side of the plug body 21, and makes the card block 55 fixedly connected to the inner arc of the elastic piece 54 gradually approach the fixed clamping ring 23 on the plug body 21. As the socket 1 and the plug body 21 are combined, the inclined surface of the card block 55 gradually contacts the inclined surface of the fixed clamping ring 23, and then the card block 55 is subjected to the reaction repulsive force of the fixed clamping ring 23, so that the card block 55 generates a compressive force on the telescopic spring 52 through the movable ring 53. When further connecting the socket 1 to the plug body 21, the movable ring 53 on the outer side of the socket 1 is pushed at the same time, so that the movable ring 53 generates a certain tensile force on the telescopic spring 52, so that the card block 55 can move along The inclined surface of the fixing clamping ring 23 slides, and causes the elastic piece 54 to which the clamping block 55 is fixed to produce elastic deformation, so that the clamping block 55 can move along the inclined surface of the fixing clamping ring 23 to the other side of the fixing clamping ring 23 until the clamping block 55 is engaged with the fixing clamping ring 23 under the restoring force of the elastic piece 54. At this time, under the restoring force of the telescopic spring 52, the clamping block 55 is stably engaged with the fixing clamping ring 23, so that the socket 1 of the RF connector and the plug body 21 can be connected to each other. When the socket 1 of the RF connector needs to be separated from the plug body 21, the sliding ring 24 outside the plug body 21 can be slid so that the sliding ring 24 squeezes the clamping block 55, so that the clamping block 55 exerts an elastic changing force on the elastic piece 54, so that the clamping block 55 can be separated from its engagement with the fixing clamping ring 23, and the RF connector socket 1 and the plug body 21 can be separated.
