Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, specifically to a quick-plug radio frequency connector. Background Technology

[0002] RF connectors are electronic components used to connect RF circuits. They are mainly used in RF signal transmission systems to connect different RF devices or components together to achieve signal transmission and reception. RF connectors typically have the characteristics of high frequency performance, low loss, and strong adaptability. With the trend of miniaturization of electronic devices, RF connectors are also becoming smaller to meet the requirements of compact design. Currently, common types of RF connectors include SMA connectors, SMB connectors, MCX connectors, N-type connectors, and TNC connectors.

[0003] Chinese utility model patent CN222735494U discloses a dual-locking radio frequency connector, including an RF connector body with a plug sleeve at the bottom and a plug head at the top. The plug sleeve has a plug cavity, and the plug cavity contains a connecting tube. The inner wall of the plug cavity has a thread, and the plug sleeve has a sliding groove with an auxiliary positioning groove inside. A locking assembly is also located within the sliding groove. The plug head has a second thread and a sealing seat. The locking assembly includes a movable ring with a T-shaped slider on its inner wall and locking teeth at the bottom. The sealing seat has a locking groove. This utility model achieves dual locking through the threaded connection and the locking assembly. The cooperation between the sealing seat and the locking teeth ensures good sealing performance of the connector. The design of the sliding groove and the movable ring makes the installation and disassembly of the locking assembly easier. The design of the buffer arc surface effectively buffers the movement of the locking teeth.

[0004] During use, the device seals the insertion sleeve and connector. The heat generated during operation cannot be dissipated in time, which will cause the parts to age and shorten their service life. Utility Model Content

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a quick-plug radio frequency connector, which has the following advantages:

[0021] 1. This quick-connect RF connector achieves quick connection and disconnection of the male and female terminals by interlocking the external thread on the outer wall of the male terminal connection and the internal thread on the inner wall of the female terminal connection. This results in a convenient and efficient connection. Furthermore, a connection component is provided inside the cavity between the male and female terminals. This connection component can be used to calibrate the male and female wire cores during connection and also to dissipate heat at the connection point when the connector is in operation.

[0022] 2. This quick-plug RF connector achieves precise alignment and connection between the male and female wire cores through a connection assembly consisting of a plug tube, a fixing tube, and a spiral tube, while also providing efficient heat dissipation. The plug tube is movably positioned inside the limiting block, allowing flexible adjustment of the male wire core's insertion angle to ensure accurate docking with the female wire core. The fixing tube securely holds the female wire core, providing a foundation for precise connection. The spiral tube, as a core component, uses its elastic structure to buffer external forces during insertion and removal, preventing damage to the wire core due to excessive stress. The hollow spiral design significantly increases the heat dissipation area. During RF signal transmission, the wire core generates heat, which the spiral tube quickly dissipates. Furthermore, outside air can pass through the interior of the spiral tube, further dissipating heat from the mounting cavity and preventing signal attenuation or equipment malfunction due to heat accumulation.

[0023] 3. This quick-plug RF connector features a pressure relief hole on the insertion tube. When the male and female terminals are installed, and the two rubber limiting and supporting blocks approach each other, the pressure inside the mounting cavity gradually increases. The pressure relief hole releases some of the air inside the mounting cavity, thus easing the internal pressure and facilitating the installation of the male and female terminals. After installation, pulling the insertion tube seals the pressure relief hole against the inner wall of the insertion port, stabilizing the pressure inside the mounting cavity. This strengthens the connection between the male and female terminals while preventing external air and moisture from entering the mounting cavity, ensuring a safe environment for the connection between the male and female wire cores.

[0037] Example 1:

[0038] This embodiment provides a quick-plug radio frequency connector with the following technical features.

[0039] Please see Figure 1-6 A quick-plug RF connector includes a male terminal 100 and a female terminal 200. The male terminal 100 has an external thread on its outer wall at the connection point, and the female terminal 200 has an internal thread on its inner wall at the connection point. The male terminal 100 and female terminal 200 are connected by the engagement of the external and internal threads. A limiting block 140 is provided inside the male terminal 100, with a male wire core 120 located at its center. A support block 240 is provided inside the female terminal 200, with a female wire core 220 located at its center. The male terminal 100 is located away from... A plug-in port 110 is provided on one side of the female terminal 200. A gap is provided between the male wire core 120 and the plug-in port 110. A wiring port 210 is provided on the side of the female terminal 200 away from the male terminal 100. A gap is provided between the female wire core 220 and the wiring port 210. A wiring groove is provided on the side of the male wire core 120 close to the female wire core 220. The male wire core 120 and the female wire core 220 are connected through the wiring groove. A connecting component 300 is provided between the male terminal 100 and the female terminal 200 for aligning and connecting the male wire core 120 and the female wire core 220 and for heat dissipation.

[0040] In an optional embodiment, the connection component 300 includes:

[0041] The insertion tube 310 is movably positioned inside the limiting block 140;

[0042] The fixing tube 320 is located inside the support block 240;

[0043] The spiral tube 330 is fixedly connected at both ends to the insertion tube 310 and the fixing tube 320, respectively.

[0044] Among them, the spiral tube 330 is a flexible, hollow, spiral tube.

[0045] In an optional embodiment, a limiting groove 130 is formed on the inner wall of the male end 100, and a limiting block 140 is fixedly disposed inside the limiting groove 130. A placement groove 230 is formed on the side of the female end 200 near the male end 100, and a support block 240 is placed inside the placement groove 230.

[0046] In an optional embodiment, the limiting block 140 has a through-hole 141, the insertion tube 310 is pluggably disposed inside the 141, the support block 240 has a through-hole fixing groove 241, and the fixing tube 320 is fixedly disposed inside the fixing groove 241.

[0047] In an optional embodiment, the cannula 310 is provided with a pressure relief hole 311, which connects the interior of the cannula 310 and the interior of the male end 100.

[0048] In an optional embodiment, the limiting block 140 and the support block 240 are elastic rubber blocks.

[0049] In an optional embodiment, a hand-held block 250 is provided on the outer side of the female end 200 to facilitate the connection between the male end 100 and the female end 200.

[0050] It should be noted that the hand-held block 250 is fixedly mounted on the outer wall of the female end 200, and the outer wall of the hand-held block 250 is provided with textures for easy gripping.

[0051] Working principle: The male end 100 has an external thread on its outer wall, and the female end 200 has an internal thread on its inner wall. Rotation allows the male end 100 and female end 200 to be connected via threaded engagement. Mounting cavities are formed on the sides of the female end 200 and male end 100 that are close to each other. The internal thread is on the inner wall of the mounting cavity of the female end 200, and the external thread is on the outer wall of the mounting cavity of the male end 100. An annular limiting groove 130 is formed inside the male end 100, and a rubber limiting block 140 is fixedly installed inside the limiting groove 130. A placement groove 230 is formed on the bottom surface of the mounting cavity of the female end 200, and a movable rubber block is placed inside the placement groove 230. The support block 240 has a male wire core 120 that passes through the center of the limiting block 140 from the insertion port 110 and extends into the interior of the mounting cavity, and a female wire core 220 that passes through the center of the support block 240 from the connection port 210 and extends into the interior of the mounting cavity. This ensures that the male wire core 120 and the female wire core 220 are fixed at the center of the male end 100 and the female end 200, so that the wire cores do not contact the inner metal wall, thereby preventing short circuits, leakage and insulation damage. A wiring groove is provided at the end of the male wire core 120 near the female wire core 220. After the male end 100 and the female end 200 are connected, one end of the female wire core 220 can be inserted into the wiring groove of the male wire core 120 for stable information transmission.In addition, a through-hole 141 is provided on the limiting block 140, with the two ends of the 141 connected to the insertion port 110 and the mounting cavity, respectively. A through-hole fixing groove 241 is provided on the support block 240, with the two ends of the fixing groove 241 connected to the wiring port 210 and the mounting cavity, respectively. A fixing tube 320 is fixedly installed inside the fixing groove 241. One end of a spiral tube 330 is fixedly connected to the side of the fixing tube 320 near the mounting cavity, and the other end of the spiral tube 330 is fixedly connected to an insertion tube 310. The insertion tube 310 is slidably connected inside the 141. During installation, the limiting block 140 is first fixedly snapped into the limiting groove 130. The support block 240 is placed inside the placement groove 230. The male wire core 120 is passed through the limiting block 140 and fixed inside the male end 100. The female wire core 220 is passed through the support block 240 and fixed inside the female end 200. At this time, the fixing tube 320, along with the spiral tube 330 and the insertion tube 310, is fixedly mounted on the support block 240. After the female end 200 and the male end 100 are brought close to each other, the spiral tube 330 can limit the female wire core 220 and the male wire core 120, thereby enabling the calibration of the end where the female wire core 220 and the male wire core 120 are connected. When the male end 100 and the female end 200 are threaded... When twisting, the insertion tube 310 is inserted into the socket 141. During the twisting connection between the male end 100 and the female end 200, the fixing tube 320 and the spiral tube 330 rotate due to the constraint of the insertion tube 310. Since the support block 240 is placed inside the placement groove 230, it can rotate along with the fixing tube 320 within the placement groove 230 as the male end 100 and female end 200 rotate. As the female end 200 and male end 100 are gradually installed, the side plate of the male end 100's mounting cavity slowly presses against the support block 240, thereby allowing the rubber... The support block 240, made of a certain material, deforms, allowing it to fit tightly against the inner wall of the placement groove 230. At this time, the support block 240 is constrained, and the fixing tube 320 is fixed. By controlling the contact position between the insertion tube 310 and the socket 141, the spiral tube 330 can be controlled to fit against the male wire core 120 and the female wire core 220. This allows outside air to pass through the interior of the fixing tube 320, insertion tube 310, and spiral tube 330, thereby dissipating the heat generated by the components inside the mounting cavity during operation. This reduces the possibility of damage to the components caused by the heat generated during operation, thus extending the service life of the connector.In addition, a pressure relief hole 311 is provided on the insertion tube 310. When the male end 100 and the female end 200 are installed together, the pressure inside the mounting cavity increases due to the proximity of the support block 240 and the limiting block 140, which could cause installation difficulties. The pressure relief hole 311 is located inside the mounting cavity to facilitate the release of air from the cavity to the outside air, ensuring that the pressure inside the mounting cavity is roughly equal to the outside air pressure. After installation, by controlling the position of the insertion tube 310, the pressure relief hole 311 is aligned with the inner wall of the socket 141. Because the mounting cavity is now sealed, the pressure is stable, resulting in a more stable connection for the connector and providing a solid mechanical guarantee for stable transmission of radio frequency signals.

[0052] In summary, this quick-connect RF connector achieves rapid connection and disconnection of the male terminal 100 and the female terminal 200 by interlocking the external thread on the outer wall of the male terminal 100 connection and the internal thread on the inner wall of the female terminal 200 connection. This results in a convenient and efficient connection. Furthermore, a connection component 300 is provided inside the cavity between the male terminal 100 and the female terminal 200. The connection component 300 can calibrate the connection of the male core 120 and the female core 220 during connection and also dissipate heat at the connection point when the connector is in operation.

[0053] This quick-plug RF connector achieves precise alignment and connection between the male core 120 and the female core 220 through a connection assembly 300 consisting of a insertion tube 310, a fixing tube 320, and a spiral tube 330, while also achieving efficient heat dissipation. The insertion tube 310 is movably positioned inside the limiting block 140, allowing for flexible adjustment of the insertion angle of the male core 120 to ensure accurate docking with the female core 220. The fixing tube 320 securely fixes the female core 220, providing a foundation for precise connection. As a core component, the spiral tube 330's elastic structure buffers external forces during insertion and removal, preventing damage to the core due to excessive force. The hollow spiral design significantly increases the heat dissipation area. During RF signal transmission, the core generates heat, which the spiral tube 330 can quickly dissipate. Furthermore, outside air can pass through the interior of the spiral tube 330, dissipating heat from the mounting cavity and preventing signal attenuation or equipment malfunction due to heat accumulation.

[0054] This quick-plug RF connector features a pressure relief hole 311 on the insertion tube 310. When the male terminal 100 and female terminal 200 are installed, and the two rubber limiting blocks 140 and support blocks 240 approach each other, the pressure inside the mounting cavity gradually increases. The pressure relief hole 311 releases some of the air inside the mounting cavity, thus easing the internal pressure and facilitating the installation of the male terminal 100 and female terminal 200. After installation, pulling the insertion tube 310 seals the pressure relief hole 311 against the inner wall of the insertion port 141, stabilizing the pressure inside the mounting cavity. This strengthens the connection between the male terminal 100 and female terminal 200 while preventing external air and moisture from entering the mounting cavity, ensuring a safe environment for the connection between the male core 120 and female core 220.
