[0025] 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.
[0026] This utility model provides, for example Figure 1-5 The radio frequency connector anti-misinsertion guide structure shown includes a guide component 2 installed at the end of the radio frequency connector socket 1. The guide component 2 assists the radio frequency connector plug end 3 to be inserted into the radio frequency connector socket end 1.
[0027] Reference Figure 3-5 The guide assembly 2 includes a mounting tube 21 that docks with the inside of the RF connector socket end 1. The end of the mounting tube 21 is connected to a guide bucket 22, which is positioned toward the RF connector plug end 3. A dust collection trough 23 is also connected to the outer side of the end edge of the guide bucket 22. The dust collection trough 23 and the outer wall of the guide bucket 22 work together. The lowest end of the guide bucket 22 is connected to the end edge of the mounting tube 21. The RF connector plug end 3 touches the inner wall of the guide bucket 22 and moves to connect with the RF connector socket end 1.
[0028] Specifically, the bottom inner side of the dust collection tank 23 is provided with multiple sets of drainage holes 24. The multiple sets of drainage holes 24 are evenly spaced and are all located at the bottom of the dust collection tank 23. The end of the guide hopper 22 is also provided with a water-blocking ring 25. The water-blocking ring 25 is located on the inner side below the drainage holes 24, and one side of the water-blocking ring 25 extends to the vertical direction of the drainage holes 24, and the inner side matches and connects with the inclined surface of the inner wall of the guide hopper 22.
[0029] Specifically, the outer wall of the guide bucket 22 is provided with multiple sets of anti-slip strips 26. Each set of anti-slip strips 26 is evenly spaced, and the anti-slip strips 26 protrude outwards. The anti-slip strips 26 are connected from the top end to the bottom end of the guide bucket 22.
[0030] Specifically, the bottom of the guide bucket 22 is connected to one end of the mounting tube 21, and one end of the mounting tube 21 is free of a docking base 27, which matches the connecting seat 31 provided on the outer wall of the RF connector plug end 3.
[0031] Specifically, the outer wall thread of the mounting tube 21 matches the inner wall thread of the RF connector socket 1, the inner wall thread of the mounting tube 21 matches the outer wall thread of the RF connector plug 3, and the end length of the RF connector plug 3 is at least sufficient to allow it to be fully inserted into the RF connector socket 1, and the working length of the guide component 2 is reserved.
[0032] In this embodiment, the mounting tube 21 is screwed into the RF connector socket 1 through its outer wall thread to ensure a tight fit. The bottom end of the guide hopper 22 is welded or snapped onto the end of the mounting tube 21, with its inclined inner wall facing the plug end 3. The dust collection tank 23 is connected to the outer edge of the guide hopper 22, and multiple sets of drainage holes 24 are evenly distributed at the bottom of the tank. A water-blocking ring 25 is provided on the inner side below the drainage holes 24, and its inner inclined surface matches the inner wall of the guide hopper 22 to prevent liquid backflow. Anti-slip strips 26 are evenly distributed on the outer wall of the guide hopper 22 to increase operating friction. The operator aligns the plug end 3 with the inclined inlet of the guide hopper 22 and guides the plug end 3 to gradually slide into the mounting tube 21 through the inner wall of the guide hopper. After the connector 31 of the plug end 3 contacts the mating base 27 of the mounting tube 21, the plug end 3 is rotated, and it engages with the mounting tube 21 through the inner wall thread until it is fully inserted and locked.
[0033] In this embodiment, the inclined design of the guide hopper 22 provides initial guidance for the plug end 3, preventing misinsertion or plug damage due to angular deviation. The matching structure of the docking base 27 and the connecting seat 31 ensures that the plug end 3 can only be inserted in the correct direction, achieving mechanical guidance. The dust collection tank 23 collects dust or foreign objects brought in during the insertion of the plug end 3, preventing contaminants from entering the socket. The drain hole 24 and the water-blocking ring 25 work together to drain liquid entering the dust collection tank, while the water-blocking ring 25 prevents liquid from seeping into the socket end along the inner wall of the guide hopper. The anti-slip strip 26 provides friction for the operator's grip, preventing slippage of the plug end 3 during insertion and improving operational stability. The double-threaded connection design of the mounting tube 21 with the socket end 1 and the plug end 3 ensures mechanical locking strength and long-term reliability. The device is suitable for outdoor or humid environments, with improved waterproof performance through drainage and water-blocking designs; the wear-resistant material of the anti-slip strip 26 and the guide hopper 22 can withstand frequent insertion and removal scenarios.
[0034] 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.
