Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically to a radio frequency coaxial connector that prevents detachment. Background Technology

[0002] Radio frequency coaxial connectors are generally considered to be components that are attached to cables or mounted on instruments, serving as elements for electrical connection or disconnection of transmission lines.

[0003] For example, CN220797338U discloses an anti-detachment radio frequency coaxial connector, including a main connector and a secondary connector. The main connector has positioning posts at four corners, and the secondary connector has positioning holes at one corner. The positioning posts and positioning holes are matched in size. A movable groove is opened in the middle of the inner wall of the secondary connector, and a pressure plate is movably connected in the movable groove. A barb groove is opened at one end of the positioning post, and a locking groove is opened at one end of the pressure plate. The locking groove and the barb groove are engaged. This utility model provides an anti-detachment radio frequency coaxial connector. By pressing the pressure plate with the positioning post, the pressure plate retracts into the movable groove. When the pressure plate lacks pressure, the return spring rebounds, so that the locking groove at one end of the pressure plate automatically engages with the barb groove on the positioning post. The operation is simple and quick. By rotating the threaded sleeve and threading the threaded tube to the threaded sleeve, the connection between the secondary connector and the main connector is reinforced by the threaded sleeve, preventing the main connector and the secondary connector from falling off due to the breakage of the positioning post.

[0004] However, although this type of anti-detachment RF coaxial connector can prevent detachment during installation, the sealing and protection effect of the RF coaxial connector connection is not high after the anti-detachment connection is made, which reduces the sealing effect of the RF coaxial connector connection.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a non-detachable radio frequency coaxial connector. Utility Model Content

[0006] The purpose of this invention is to provide an anti-detachment radio frequency coaxial connector to solve the problem mentioned in the background art that the sealing and protection effect of the installation and connection parts of the radio frequency coaxial connector is not high after the anti-detachment connection of the radio frequency coaxial connector is made.

A spring is sleeved on the outer wall of the telescopic rod and fixedly connected to the outer wall of the connecting box. A pull block is fixedly connected to one end of the spring and fixedly connected to one end of the telescopic rod.

[0008] Furthermore, the outer wall of the coaxial connector body is provided with a second nut, and the inner wall of the second nut is threaded with a second bolt that is slidably connected to the outer wall of the second sliding block. A positioning groove is provided at the connection between the outer wall of the second sliding block and the second bolt.

[0009] Furthermore, the coaxial connector body forms an installation structure with the connecting tube through an outer spiral and an inner spiral. The slot is set on the movement trajectory of the first bolt. There are two sets of the first bolt, and the positions of the two sets of the first bolt are symmetrical about the central axis of the conveying tube.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figures 1-6 As shown, an anti-detachment radio frequency coaxial connector includes a connecting tube 1, a coaxial connector body 2 threadedly connected to the inner wall of the connecting tube 1, a delivery tube 3 fixedly connected to the end of the coaxial connector body 2, an outer spiral 4 on the outside of the coaxial connector body 2, an inner spiral 5 at the connection between the inner wall of the connecting tube 1 and the outer spiral 4, a first nut 6 on the outer wall of the connecting tube 1, a first bolt 7 threadedly connected to the inner wall of the first nut 6 and slidably connected to the outer wall of the delivery tube 3, a groove 8 at the connection between the outer wall of the delivery tube 3 and the first bolt 7, a first sliding block 22 slidably connected to the outer wall of the coaxial connector body 2, a groove 9 at the connection between the outer wall of the coaxial connector body 2 and the first sliding block 22, and a fixed outer wall of the coaxial connector body 2. A first sealing cover 10 is fixedly connected. A second sliding block 11 located on one side of the first sliding block 22 is slidably connected to the outer wall of the coaxial connector body 2. A second sealing cover 12 is fixedly connected to the outer wall of the second sliding block 11. A connecting box 13 is fixedly connected to the outer wall of the first sliding block 22. A locking rod 14 slidably connected to the outer wall of the connecting box 13 is fixedly connected to the outer wall of the second sliding block 11. A locking block 15 engaging with the outer wall of the locking rod 14 is slidably connected to the inner wall of the connecting box 13. A telescopic rod 16 slidably connected to the outer wall of the connecting box 13 is fixedly connected to the outer wall of the telescopic rod 16. A spring 17 fixedly connected to the outer wall of the connecting box 13 is sleeved on the outer wall of the telescopic rod 16. A pull block 18 fixedly connected to one end of the telescopic rod 16 is fixedly connected to one end of the spring 17.

[0027] Furthermore, the outer wall of the coaxial connector body 2 is provided with a second nut 19, and the inner wall of the second nut 19 is threaded with a second bolt 20 that is slidably connected to the outer wall of the second sliding block 11. The connection part between the outer wall of the second sliding block 11 and the second bolt 20 is provided with a positioning groove 21, which facilitates the convenient storage and use of the protective cover through the setting of the positioning groove 21.

[0028] Furthermore, the coaxial connector body 2 forms an installation structure with the connecting tube 1 through the outer spiral 4 and the inner spiral 5. The slot 8 is set on the movement trajectory of the first bolt 7. There are two sets of the first bolt 7. The positions of the two sets of first bolt 7 are symmetrical about the central axis of the conveying tube 3, which is conducive to the convenient threaded connection between the coaxial connector body 2 and the connecting tube 1 through the threaded connection of the outer spiral 4 and the inner spiral 5, so as to achieve the effect of preventing the coaxial connector from falling off.

[0029] Furthermore, the sliding groove 9 is configured in a one-to-one correspondence with the second sliding block 11 and the first sliding block 22, which facilitates convenient sliding between the protective covers.

[0030] Furthermore, the connecting box 13 is set on the movement trajectory of the lever 14, and the outer wall of the connecting box 13 and the connection part of the lever 14 are provided with slots, which is conducive to achieving the effect of pre-positioning and engaging the protective covers by setting the connecting box 13 on the movement trajectory of the lever 14.

[0031] Furthermore, the pressing parts of the clamping rod 14 and the clamping block 15 are inclined, and the outer wall contour of the engaging part of the clamping rod 14 and the clamping block 15 is flat. This facilitates the easy engaging and fixing of the protective covers by setting the pressing parts of the clamping rod 14 and the clamping block 15 to be inclined.

[0032] Furthermore, the first sealing cover 10 forms a locking structure with the second sealing cover 12 through the locking rod 14 and the locking block 15. The outer wall contours of the first sealing cover 10 and the second sealing cover 12 are both semi-circular, which facilitates the locking connection of the locking rod 14 and the locking block 15, and drives the first sealing cover 10 and the second sealing cover 12 to be easily locked and fixed, so as to achieve the effect of convenient sealing of the connector installation and connection parts.

[0033] Furthermore, the inner wall contour of the positioning groove 21 is adapted to the outer wall contour of the second bolt 20, which helps to improve the stability of the protective cover when it is not in use.

[0034] Working principle: When using this type of anti-detachment RF coaxial connector, firstly, after assembling the RF coaxial connector for anti-detachment connection, in order to improve the sealing effect of the connection part between the RF coaxial connector and the pipeline, after the RF coaxial connector is threaded and installed, the first sliding block 11 and the second sliding block 22 can be slid so that the locking rod 14 is inserted into the connection box 13. With the locking rod 14 and the locking block 15 pressing part at an angle, the telescopic rod 16 and the spring 17 are pressed until the connection part of the locking rod 14 and the locking block 15 is flat, achieving the effect of convenient locking and fixing between the protective cover, and effectively sealing the connection part between the RF coaxial connector and the pipeline.

[0035] Finally, when sealing the RF coaxial connector mounting joint with the protective cover, in order to improve the storage effect of the protective cover when not in use, the second sliding block 11 and the first sliding block 22 can be slid, and the second bolt 20 can be rotated by the limiting effect of the second nut 19, so that the second bolt 20 slides into the inner wall of the positioning groove 21, thereby improving the storage stability of the protective cover.

[0036] This is the working principle of this type of anti-detachment RF coaxial connector.
