Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, and in particular to a self-locking radio frequency coaxial connector. Background Technology

[0002] Radio frequency coaxial connectors are often regarded as components that are attached to cables or installed on instruments. They play a key role in the electrical connection or disconnection of transmission lines. As mechatronic products, they act as a bridge in signal transmission and are an indispensable core component in building coaxial transmission systems.

[0003] Most existing common RF coaxial connectors use threaded connections. However, in actual use, external environmental factors such as vibration and impact can easily cause these connections to loosen, leading to signal transmission interruption or attenuation, severely affecting the normal operation of the communication system. Furthermore, when connecting the connector, it is often difficult to determine if the connection is in the correct position. If the connection is too loose, the signal cannot be effectively transmitted; if the connection is too tight, it may damage the connector plug. To overcome these disadvantages, this invention provides a self-locking RF coaxial connector. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-locking radio frequency coaxial connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking radio frequency coaxial connector, comprising a signal line, a male connector head and a female connector head, a plug fixedly connected to one end of the signal line, a socket opening at one end of the signal line, positioning components at one end of the signal line and on both sides of the plug, an external threaded tube fixedly connected to one end of the male connector head, an internal threaded tube fixedly connected to one end of the female connector head, self-locking components on both sides of one end of the male connector head, and a disassembly component on the male connector head.

[0006] Furthermore, the positioning component includes a positioning head fixedly connected to one end of the signal line and located on both sides of the plug, and a positioning hole fixedly connected to one end of the signal line and located on both sides of the socket, with the positioning hole and the positioning head being slidably connected.

[0007] Furthermore, a sealing ring is fixedly connected inside the internally threaded tube.

[0008] Furthermore, the self-locking assembly includes connecting plates fixedly connected to both sides of one end of the male connector, a spring fixedly connected to one side of the connecting plate, a first magnetic block fixedly connected to one end of the spring, and slots opened on both sides inside the female connector, with the slots and the first magnetic block engaging with each other.

[0009] Furthermore, the disassembly assembly includes a pair of grooves formed on the male connector, a movable ring slidably connected to the grooves, and a plurality of second magnetic blocks fixedly connected to one side of the movable ring.

[0010] Furthermore, several sliding plates are fixedly connected to the movable ring.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention uses a spring on the self-locking assembly to push the first magnetic block into the slot to fix the male and female connectors together, preventing the connection between the external and internal threaded tubes from loosening due to external factors such as vibration. During the connection process, the spring pushes the first magnetic block into the slot, and the collision between the first magnetic block and the slot produces a sound, thus reminding the operator to connect to the correct position and avoiding signal failure due to an overly loose connection or damage to the plug due to an overly tight connection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, a self-locking radio frequency coaxial connector is disclosed, including a signal line 3, a male connector 1 and a female connector 2 on the signal line 3, a plug 4 fixedly connected to one end of the signal line 3, a socket 6 opened at one end of the signal line 3, positioning components on one end of the signal line 3 and located on both sides of the plug 4, an external threaded tube 8 fixedly connected to one end of the male connector 1, an internal threaded tube 9 fixedly connected to one end of the female connector 2, self-locking components on both sides of one end of the male connector 1, and a disassembly component on the male connector 1.

[0022] As shown in the figure, the positioning component includes a positioning head 5 fixedly connected to one end of the signal line 3 and both sides of the plug 4, and a positioning hole 7 fixedly connected to one end of the signal line 3 and both sides of the socket 6. The positioning hole 7 and the positioning head 5 are slidably connected and are used to provide positioning guidance during connection.

[0023] As shown in the figure, a sealing ring 10 is fixedly connected inside the internally threaded pipe 9 to seal it and prevent impurities such as water vapor and dust from entering.

[0024] As shown in the figure, the self-locking assembly includes a connector male head 1 with a connecting plate 11 fixedly connected to both sides of one end, a spring 12 fixedly connected to one side of the connecting plate 11, a first magnetic block 13 fixedly connected to one end of the spring 12, and slots 14 opened on both sides inside the connector female head 2. The slots 14 and the first magnetic block 13 are locked together to prevent the connection between the internal threaded tube 9 and the external threaded tube 8 from loosening.

[0025] As shown in the figure, the disassembly assembly includes a slide groove 15 formed on the male connector 1. A movable ring 16 is slidably connected to the slide groove 15. Several second magnetic blocks 18 are fixedly connected to one side of the movable ring 16. The second magnetic blocks 18 are used to attract the first magnetic block 13 to leave the slot 14, thereby disassembling it.

[0026] As shown in the figure, several sliding plates 17 are fixedly connected to the movable ring 16, which are used to make the movable ring 16 slide on the slide groove 15.

[0027] Working principle: When using, first check if the entire device is intact. After the check is completed, align the positioning head 5 on the male connector 1 with the insertion port 6 of the female connector 2. Then rotate the male connector 1 so that the external thread tube 8 enters the internal thread tube 9. The female connector 2 squeezes the first magnetic block 13, causing the spring 12 to contract. When the first magnetic block 13 can enter the slot 14, it is connected to the appropriate position. At this time, the spring 12 pushes the first magnetic block 13 into the slot 14. The first magnetic block 13 and the slot 14 collide and produce a sound. When the operator raises the sound produced by the collision, stop rotating, thus completing the connection between the signal lines 3. When disassembly is required, the operator pushes the movable ring 16 to slide on the slide groove 15 through the sliding plate 17 to move the second magnetic block 18 to one side of the connecting plate 11. The second magnetic block 18 attracts the first magnetic block 13, causing the first magnetic block 13 to leave the slot 14. Then rotate the male connector 1 to disassemble it.
