Description

Technical Field

[0001] This utility model specifically relates to an anti-loosening radio frequency coaxial connector. Background Technology

[0002] RF coaxial connectors are key components used to connect and disconnect RF transmission lines, and are widely used in communication equipment, aerospace, military radar, testing instruments, and various consumer electronics. Their core function is to achieve stable, low-loss signal transmission under high-frequency conditions; therefore, the reliability and stability of the connection are paramount.

[0003] Currently, most common RF coaxial connectors on the market use threaded connections. This structure provides mechanical fixation and electrical contact through the threaded engagement between the inner and outer conductors. However, in practical applications, especially in harsh environments involving vibration, shock, temperature cycling, or frequent insertion and removal, traditional threaded connections are prone to relative displacement under dynamic mechanical stress, leading to gradual loosening of the connection. This loosening causes increased contact resistance and impedance mismatch, resulting in increased signal reflection and insertion loss, and in severe cases, even communication interruptions and signal distortion.

[0004] Therefore, it is necessary to invent an anti-loosening radio frequency coaxial connector to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes an anti-loosening radio frequency coaxial connector, which can prevent the radio frequency connector from becoming loose.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening radio frequency coaxial connector, including a radio frequency connector plug end and a radio frequency connector socket end, with an anti-loosening component and an anti-rotation clamp respectively installed on the outside of the two. After the radio frequency connector plug end and the radio frequency connector socket end are mated, the anti-loosening component is installed on the outside of the anti-rotation clamp. The outer wall of the RF connector plug end is provided with multiple movable slots, and the anti-loosening component is installed in the multiple movable slots. The anti-rotation clamp is fixed to the outer wall of the RF connector socket end. The anti-loosening component includes a positioning sleeve, the inner wall of which is provided with a moving block that matches the moving groove, the bottom of which is provided with a positioning groove that matches the anti-rotation hoop, the overall cross-section of the anti-rotation hoop is polygonal, the outer wall of which is provided with symmetrical anti-detachment components, the anti-detachment components extending into the positioning groove and positioned below the anti-rotation hoop.

[0007] Preferably, the anti-rotation hoop has a hexagonal overall cross-section, the positioning groove has a cross-section corresponding to the anti-rotation hoop, and the outer wall of the positioning sleeve has a plurality of symmetrical telescopic holes, in which the anti-detachment component is installed.

[0008] Preferably, the anti-detachment component includes two sets of anti-detachment protrusions installed in the telescopic hole. The tail of the two sets of anti-detachment protrusions is provided with a connecting rod. The outer wall of the anti-detachment protrusion is also provided with a limiting plate. The openings at both ends of the telescopic hole are provided with limiting rings that match the limiting plate. The outer wall of the anti-detachment protrusion is provided with a compression spring between the limiting plate and the limiting ring. The connecting rod connects the ends of the two sets of anti-detachment protrusions.

[0009] Preferably, one end of the anti-detachment protrusion is hemispherical.

[0010] Preferably, the internal depth of the positioning groove should at least exceed the overall thickness of the anti-rotation hoop, and the anti-detachment component is disposed at the bottom of the anti-rotation hoop.

[0011] Preferably, the movable block is matched with the movable groove, and both have a T-shaped cross-section. The length of the movable groove is such that the positioning sleeve is fitted outside the anti-rotation hoop.

[0012] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: The anti-rotation hoop of this utility model has a polygonal cross section, and the positioning groove cross section of the positioning sleeve corresponds completely to the anti-rotation hoop. When the positioning sleeve is fitted on the outside of the anti-rotation hoop, the polygonal structure can directly restrict the circumferential rotation of the anti-rotation hoop, reducing the loosening problem caused by vibration and impact in traditional threaded connections. The compression spring of this invention always applies an inward elastic force to the anti-detachment protrusion, so that the anti-detachment protrusion is tightly attached to the bottom of the anti-rotation hoop, preventing the positioning sleeve from separating from the anti-rotation hoop along the axial direction. The anti-detachment protrusion offsets the external force through rigid support, preventing the connector plug end from accidentally separating from the socket end. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-4 The present invention relates to an anti-loosening radio frequency coaxial connector, comprising a radio frequency connector plug end 1 and a radio frequency connector socket end 2, wherein an anti-loosening component 3 and an anti-rotation clamp 4 are respectively installed on the outside of the two. After the radio frequency connector plug end 1 and the radio frequency connector socket end 2 are mated, the anti-loosening component 3 is installed on the outside of the anti-rotation clamp 4. Specifically, the outer wall of the RF connector plug end 1 is provided with multiple moving slots 11, and anti-loosening components 3 are installed in the multiple moving slots 11. Anti-rotation clamps 4 are fixed to the outer wall of the RF connector socket end 2. Specifically, the anti-loosening component 3 includes a positioning sleeve 31, the inner wall of the positioning sleeve 31 is provided with a moving block 32 that matches the moving groove 11, the bottom of the positioning sleeve 31 is provided with a positioning groove 33 that matches the anti-rotation hoop 4, the overall cross-section of the anti-rotation hoop 4 is polygonal, the outer wall of the positioning sleeve 31 is provided with symmetrical anti-detachment components 5, the anti-detachment components 5 extend into the positioning groove 33 and are placed below the anti-rotation hoop 4.

[0018] Specifically, the anti-rotation hoop 4 has a hexagonal cross-section, the positioning groove 33 has a cross-section corresponding to the anti-rotation hoop 4, and the outer wall of the positioning sleeve 31 has a plurality of symmetrical telescopic holes 34, in which anti-detachment components 5 are installed.

[0019] Specifically, the anti-detachment component 5 includes two sets of anti-detachment protrusions 51 installed in the telescopic hole 34. The tail of the two sets of anti-detachment protrusions 51 is provided with a connecting rod 52. The outer wall of the anti-detachment protrusion 51 is also provided with a limiting plate 53. The openings at both ends of the telescopic hole 34 are provided with a limiting ring 35 that matches the limiting plate 53. The outer wall of the anti-detachment protrusion 51 is provided with a compression spring 54 between the limiting plate 53 and the limiting ring 35. The connecting rod 52 connects the ends of the two sets of anti-detachment protrusions 51.

[0020] Specifically, one end of the anti-detachment protrusion 51 is set as a hemispherical shape.

[0021] Specifically, the internal depth of the positioning groove 33 should at least exceed the overall thickness of the anti-rotation hoop 4, and the anti-detachment component 5 is located at the bottom of the anti-rotation hoop 4.

[0022] Specifically, the movable block 32 is matched with the movable groove 11, and both have a T-shaped cross section. The length of the movable groove 11 is such that the positioning sleeve 31 is fitted onto the outside of the anti-rotation hoop 4.

[0023] Specifically, the RF connector plug end 1 and socket end 2 are processed according to the design specifications. Multiple T-shaped moving grooves 11 are opened on the outer wall of the plug end 1, and a hexagonal anti-rotation clamp 4 is fixed on the outer wall of the socket end 2. The anti-loosening component 3 is prepared. The inner wall of the positioning sleeve 31 is processed with T-shaped moving blocks 32 that match the moving grooves 11. The bottom is opened with a positioning groove 33 that matches the cross section of the anti-rotation clamp 4. Multiple telescopic holes 34 are symmetrically opened on the outer wall. The anti-detachment component 5 is assembled. The hemispherical anti-detachment protrusion 51 with a limiting plate 53 is inserted into the telescopic hole 34. A compression spring 54 is sleeved between the limiting plate 53 and the limiting ring 35 at the opening of the telescopic hole 34. The ends of the two sets of anti-detachment protrusions 51 are connected by a connecting rod 52 to ensure that the anti-detachment protrusions 51 can elastically expand and contract along the telescopic hole 34.

[0024] Specifically, the RF connector plug end 1 and socket end 2 are precisely aligned to achieve the basic connection for signal transmission. Then, the positioning sleeve 31 is aligned with the T-shaped moving groove 11 of the plug end 1 via the inner wall T-shaped moving block 32, and the positioning sleeve 31 is directionally slid along the moving groove 11, so that the positioning sleeve 31 gradually fits onto the anti-rotation hoop 4. During the sliding process, the anti-rotation hoop 4 squeezes the hemispherical end of the anti-detachment protrusion 51, pushes the anti-detachment protrusion 51 to compress the spring 54 and retract into the telescopic hole 34. When the positioning sleeve 31 slides until the positioning groove 33 completely covers the anti-rotation hoop 4, the anti-detachment protrusion 51 is reset under the elastic force of the compression spring 54, extends into the positioning groove 33 and engages with the bottom of the anti-rotation hoop 4, completing the anti-loosening assembly.

[0025] Specifically, if it is necessary to disassemble the connector, pull the connecting rod 52 on the outer wall of the positioning sleeve 31 to both sides, which will cause the two sets of anti-detachment protrusions 51 to compress the spring 54 synchronously and exit the positioning groove 33. Then slide the positioning sleeve 31 in the opposite direction along the moving groove 11 to disengage it from the anti-rotation clamp 4. Finally, separate the plug end 1 from the socket end 2.

[0026] In this embodiment, the hexagonal anti-rotation clamp 4 is rigidly fitted with the positioning groove 33, directly restricting the circumferential rotation of the anti-rotation clamp 4 and avoiding the loosening problem caused by vibration and impact in traditional threaded connections; the anti-detachment component 5 continuously applies force to the anti-detachment protrusion 51 through the compression spring 54, making it tightly adhere to the bottom of the anti-rotation clamp 4, forming an axial lock, effectively preventing the positioning sleeve 31 from separating from the anti-rotation clamp 4, preventing the plug end 1 from accidentally detaching from the socket end 2, and ensuring connection stability.

[0027] In this embodiment, the guiding cooperation between the T-shaped moving block 32 and the moving groove 11 ensures that the positioning sleeve 31 slides precisely without repeated alignment; the hemispherical design of the anti-detachment protrusion 51 reduces assembly resistance, allowing for tool-free operation throughout the process and improving assembly efficiency; during disassembly, simply pulling the connecting rod 52 is sufficient to release the lock, facilitating later inspection and component replacement and reducing maintenance costs.

[0028] In this embodiment, the T-shaped moving structure limits the radial offset of the positioning sleeve 31 to prevent the component from shaking during vibration; the limiting plate 53 cooperates with the limiting ring 35 to lock the extension and retraction stroke of the anti-detachment protrusion 51 to prevent it from over-extension and retraction leading to failure; the positioning groove 33 covers the thickness of the anti-rotation hoop 4, increasing the contact area, improving the overall structural rigidity, and extending the service life of the connector.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
