Description

Technical Field

[0001] This utility model specifically relates to a waterproof radio frequency connector. Background Technology

[0002] As a key component for transmitting high-frequency signals, radio frequency connectors are widely used in equipment such as 5G base stations, IoT terminals, new energy vehicle in-vehicle systems, and communication cabinets. These devices are often located in open-air or humid environments, where water molecules in the air can easily seep into the device through the connector interface, leading to corrosion of the inner conductor, deterioration of the insulator performance, and ultimately signal interruption or equipment failure.

[0003] Existing waterproof RF connectors mostly adopt the structure of inner conductor, slotted insulator, and sealing ring. The sealing groove needs to be machined on precision parts, which not only increases the processing difficulty, but also easily leads to the twisting and displacement of the sealing ring and loss of waterproof function if the tolerance of the parts exceeds the standard during assembly.

[0004] Therefore, it is necessary to invent a waterproof radio frequency 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 a waterproof radio frequency connector that can prevent water from entering the radio frequency connector.

[0015] 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.

[0016] This utility model provides, for example Figure 1-6 The waterproof radio frequency connector shown includes a plug assembly 1 and a socket assembly 2. A waterproof component 3 is installed on the outer wall of the plug assembly 1, and the waterproof component 3 is connected to the top of the socket assembly 2. Specifically, the plug assembly 1 includes a plug end 11 and a built-in inner conductor. The outer wall of the plug end 11 is provided with an annular groove 12, a sealing ring 4 is installed in the annular groove 12, and a waterproof component 3 is installed outside the sealing ring 4. Specifically, the socket assembly 2 includes a socket end 21, the top outer wall of the socket end 21 is provided with a thread 22, the inside of the socket end 21 is provided with a conductor mating tube 23 that matches the inner conductor, and the bottom inner wall of the waterproof assembly 3 is connected to the thread 22. Specifically, the waterproof component 3 includes a waterproof ring 31, with a sealing groove 32 on the inner side of the waterproof ring 31 that matches the sealing ring 4, and a rotating groove 33 on the outer wall of the waterproof ring 31. A mating ring 34 is installed in the rotating groove 33, and a thread 35 matching the thread 22 is provided on the lower part of the inner wall of the mating ring 34. The mating ring 34 rotates in the rotating groove 33 and is connected to the top outer side of the socket end 21.

[0017] Specifically, the outer sides of both the upper and lower ends of the waterproof ring 31 are beveled, and the cross section of the rotating groove 33 is T-shaped. The inner side of the mating ring 34 is provided with a rotating ring 36 that matches the rotating groove 33. The upper and lower sides of the rotating ring 36 are provided with matching extension rings 37. The rotating ring 36 and the extension ring 37 are installed in the rotating groove 33.

[0018] Specifically, the top of the mating ring 34 covers the top of the waterproof ring 31, and the top and bottom outer sides of the mating ring 34 are also set as bevels, and the inner diameter of the top of the mating ring 34 is smaller than its inner diameter at the bottom.

[0019] Specifically, the inner thread 35 on the bottom of the mating ring 34 is screwed onto the outer side of the top of the socket end 21, and the inner diameter of the bottom of the mating ring 34 matches the outer diameter of the top of the socket end 21.

[0020] Specifically, the thread length of thread 122 is at least greater than the thread length of thread 235.

[0021] In this embodiment, the plug assembly 1 is first pre-processed: the sealing ring 4 of elastic material is embedded in the pre-set annular groove 12 on the outer wall of the plug end 11 to ensure that the sealing ring 4 completely fits the inner wall and bottom of the annular groove 12 without any offset or wrinkles.

[0022] Specifically, take the waterproof ring 31 from the waterproof assembly 3, align the sealing groove 32 on its inner side with the sealing ring 4 on the plug end 11, and slide it in axially along the plug end 11 until the sealing groove 32 and the sealing ring 4 are fully engaged. At this time, the waterproof ring 31 is tightly connected to the plug end 11 through the sealing ring 4, which not only achieves initial waterproofing but also fixes the axial position of the waterproof ring 31, preventing it from sliding during subsequent operations.

[0023] Specifically, since the rotating groove 33 of the waterproof ring 31 has a T-shaped cross-section, and the inner side of the mating ring 34 is provided with a matching rotating ring 36 and an extension ring 37, the mating ring 34 needs to be inserted from the top or bottom of the waterproof ring 31, so that the rotating ring 36 is embedded in the transverse groove of the T-shaped rotating groove 33, and the extension ring 37 fits against the longitudinal groove wall of the rotating groove 33. After assembly, the mating ring 34 can rotate freely in the rotating groove 33, but due to the limitation of the T-shaped structure and the extension ring 37, it cannot be detached from the waterproof ring 31, forming a rotatable but not separable mating relationship.

[0024] In this embodiment, the plug assembly 1, which has been assembled with waterproof component 3, is held in hand, and its inner conductor at the plug end 11 is aligned with the conductor connector 23 of the socket assembly 2. The inner conductor is slowly brought closer axially until it is initially inserted into the conductor connector 23.

[0025] Specifically, keep the plug assembly 1 and the socket assembly 2 axially aligned, and rotate the mating ring 34 in the waterproof assembly 3 by hand or with a tool. Since the second thread 35 on the lower part of the inner wall of the mating ring 34 matches the first thread 22 of the socket end 21, the second thread 35 will gradually screw in along the first thread 22 during the rotation, driving the plug assembly 1 to be further axially advanced until the inner conductor is fully inserted into the conductor mating pipe 23.

[0026] Specifically, the length of thread 22 is at least longer than the length of thread 35. Therefore, after tightening, thread 35 will be completely covered by thread 22, with no exposed thread gap. At the same time, it ensures that the bottom inner diameter of the mating ring 34 is completely in contact with the top outer diameter of the socket end 21, eliminating radial gap.

[0027] In this embodiment, after tightening, the top of the mating ring 34 will naturally cover the top of the waterproof ring 31, and the design of the top inner diameter of the mating ring 34 being smaller than the bottom inner diameter will make its top more tightly wrap around the outer wall of the waterproof ring 31, further strengthening the axial seal; at the same time, the beveled design at the upper and lower ends of the waterproof ring 31 can reduce scratching during assembly and ensure smooth cooperation of each component.

[0028] In this embodiment, the triple fit between the sealing ring 4, the annular groove 12, and the sealing groove 32 forms the first radial waterproof barrier, which can block most of the water that seeps in along the gap between the plug end 11 and the waterproof ring 31. Specifically, the top of the mating ring 34 covers the top of the waterproof ring 31, and the inner diameter of the top of the mating ring 34 is smaller, forming a wrap-around axial seal to prevent moisture from seeping in from the gap at the top of the waterproof ring. Specifically, thread 22 completely covers thread 35, and the bottom of the mating ring 34 fits against the outer diameter of the top of the socket end 21, eliminating thread gaps and preventing moisture from seeping in from the threaded connection.

[0029] In this embodiment, the inner conductor of the plug assembly 1 is precisely matched with the conductor mating tube 23 of the socket assembly 2, and the axial advance is smooth during the tightening process, ensuring that the inner conductor is fully inserted into the conductor mating tube 23, without poor contact problems, and with low signal transmission loss. Specifically, the mating length of thread 22 and thread 35 is sufficient to form a strong fixing force after tightening, preventing the connector from loosening under vibration and collision. At the same time, the design of the mating ring that can rotate but does not separate ensures that only the mating ring rotates when tightened, without causing the plug or waterproof ring to shift, further ensuring connection stability.

[0030] 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.
