Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connectors, and specifically to a radio frequency coaxial connector that can be rotated arbitrarily. Background Technology

[0002] RF connectors are components that connect to coaxial cables, microstrip lines, or other RF transmission lines to achieve electrical connection, disconnection, or conversion between different types of transmission lines. Rotatable RF coaxial connectors are specially designed connectors that allow a portion of the connector to rotate around an axis after it is fixed, without affecting the integrity of the transmitted signal. These connectors play a crucial role in applications requiring dynamic positioning. Existing rotating RF coaxial connectors suffer from problems such as unstable connections, poor contact leading to poor signal quality, limited rotation angle, and inability to rotate after being fixed. Utility Model Content

[0005] Preferably, the main cavity has a 90° L-shaped bend.

[0006] Preferably, the lower end of the input terminal is fixed to the flange.

[0011] Beneficial effects: This utility model proposes a freely rotatable RF coaxial connector. The output and input ends are connected to the main cavity respectively, ensuring stable connection. A retaining ring is provided between the input end and the main cavity to prevent detachment after connection. Furthermore, the output end can rotate at any angle around the axis of the input end. The rotating part provides a stable and reliable connection with good signal integrity. The 90° bend structure design of the main cavity facilitates connection of devices within limited space. The separate design of the input and output ends facilitates customized device design. Attached Figure Description

[0016] like Figures 1-4 As shown, this utility model proposes a freely rotatable radio frequency coaxial connector, including an input terminal 1, an output terminal 3, a main cavity 2, a flange 4, and a retaining ring 5. The input terminal 1 and the output terminal 3 are connected through the main cavity 2, which has a 90° bent structure and includes a horizontal cavity 21 and a vertical cavity 22. The upper end of the input terminal 1 is provided with an elastic contact 11, which is elastically connected to the vertical cavity 22 of the main cavity 2 with a snap-fit. The input terminal 1 is also provided with a retaining ring 5, which allows the input terminal 1 to be movably connected to the main cavity 2. The retaining ring 5 ensures that the input terminal 1 will not fall off after being connected to the main cavity 2. The main cavity 2 can rotate at any angle along the input terminal 1. The inner side of the vertical cavity 22 is provided with a tapered opening 24, which is connected to the input terminal 1. The tapered opening 24 further ensures the reliability of the connection between the input terminal 1 and the main cavity 2. The snap-fit ​​connection between the input terminal and the main cavity, relying on the retaining ring, is a performance guarantee for rotational function and good contact. The inner side of the transverse cavity 21 of the main cavity 2 is provided with a thread 23, and the output end 3 is provided with an external thread 31. The external thread 31 of the output end 3 and the thread 23 of the transverse cavity 21 are engaged to form a threaded connection, which ensures a stable and reliable connection.

[0017] The input end 1 is fixed to the flange 4 at its tail end, and the output end 3 is connected to the main cavity 2 and can rotate clockwise or counterclockwise along the axis of the input end 1 as the main cavity 2 rotates. An interface is provided on the other side of the output end 3. The advantage of the separate design of the input end 1 and the output end 3 is that it can be highly customized. For example, the interface of the output end 3 can be replaced with other interface forms, and the form of the flange 4 and the tail end shape of the input end 1 can be customized according to requirements.
