Description

Technical Field

[0001] This utility model specifically relates to a self-locking anti-rotation radio frequency coaxial connector. Background Technology

[0002] As a key component for the electrical connection or disconnection of transmission lines, RF coaxial connectors play a "bridge" role in modern wireless communication systems, connecting RF devices to cables to achieve reliable transmission and shielding of high-frequency signals. With the booming development of wireless communication, the performance requirements for RF connectors have expanded from a single electrical connection function to include ease of use, reliability, and resistance to environmental interference.

[0003] Most mainstream RF coaxial connectors on the market currently use a threaded connection structure. This type of connection structure requires multiple rotations of the thread to achieve connection and separation, which is not suitable for occasions that require rapid installation and debugging. Moreover, it relies solely on the thread preload to resist vibration, and is prone to loosening and rotation in strong vibration environments such as airborne, shipborne, and vehicle-mounted environments, leading to signal interruption or poor contact. After the threaded connection is installed, additional auxiliary anti-loosening measures such as steel wire binding are required. Disassembly requires special tools, which is time-consuming and not suitable for high-density installation in small spaces.

[0004] Therefore, it is necessary to invent a self-locking anti-transformation RF 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 a self-locking anti-rotation radio frequency coaxial connector, which can prevent the connector from rotating after connection.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a self-locking anti-rotation radio frequency coaxial connector, comprising a plug and a socket of the radio frequency coaxial connector, wherein the plug and the socket are externally equipped with mutually matching locking components and unlocking components; The outer wall of the plug has a plurality of evenly spaced locking holes inside the handle portion. The unlocking component is installed on the top of the locking holes, and the locking component is inserted into the bottom of the locking holes. The outer wall of the socket has a plurality of evenly spaced telescopic grooves inside the handle portion, and the locking component is installed in the plurality of telescopic grooves; The locking assembly includes a plurality of locking pins installed in the telescopic groove. The plurality of locking pins extend and retract from the telescopic groove into the locking hole. A push-pull ring is fixed to the outside of the plurality of locking pins. The push-pull ring moves vertically with the locking pins. The unlocking component includes an unlocking ring disposed at the top of the locking hole, and a plurality of unlocking pins are installed at the bottom of the unlocking ring, which push the plurality of locking pins out of the locking hole.

[0007] Preferably, the locking hole is provided with limiting rings at both the upper and lower ends, the unlocking post is provided with a limiting plate matching the limiting rings on its outer wall, and the top of the unlocking post and the top of the locking post are both hemispherical.

[0008] Preferably, a limiting buckle is provided at the opening of the telescopic groove, a stop block is provided at the bottom of the locking post to match the limiting buckle, a locking spring is fixed between the bottom of the locking post and the bottom of the telescopic groove, one side of the telescopic groove opens to the outside of the socket, and one side of the bottom of the locking post extends and is fixed to the inside of the push-pull ring.

[0009] Preferably, the push-pull ring is fixed to the outer side of the bottom of the plurality of locking posts, and the top of the push-pull ring is provided with multiple anti-slip grooves.

[0010] Preferably, when the plug is mated and locked with the socket, the locking hole is exactly matched with the position of the locking post, and the size of the locking post and the size of the unlocking post are both matched with the locking hole.

[0011] Preferably, the length of the telescopic groove is sufficient for the locking pin to enter the locking hole.

[0012] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: 1. When the plug and socket of this utility model are connected, the locking pin in the telescopic groove of the socket is automatically embedded in the locking hole of the plug under the action of the locking spring, forming a rigid locking structure of the pin hole. Compared with the traditional threaded connection, this self-locking method does not require additional screwing operation, and the locking pin and locking hole are precisely matched in size, which can maintain the locked state continuously and effectively prevent the connector from accidentally falling off in the vibration environment. 2. The locking holes and telescopic grooves of this utility model are symmetrically arranged with multiple evenly spaced holes. After multiple locking pins are simultaneously embedded in the corresponding locking holes, the relative rotation of the plug and socket can be restricted from the circumference. The inner and outer conductors of the RF connector need to be precisely coaxially aligned to ensure signal transmission quality. The anti-rotation function can avoid contact offset of the inner conductor and poor shielding of the outer conductor caused by rotation, thereby reducing signal reflection, insertion loss and other problems, and ensuring the stability of high-frequency signal transmission.

[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 self-locking anti-transformation radio frequency coaxial connector shown includes a plug 1 and a socket 2 of the radio frequency coaxial connector, and a mutually matching locking component 3 and unlocking component 4 are installed on the outside of the plug 1 and the socket 2. Specifically, the outer wall of the plug 1 has a plurality of evenly spaced locking holes 11 inside the handle portion, the unlocking component 4 is installed on the top of the locking hole 11, and the locking component 3 is inserted into the bottom of the locking hole 11; Specifically, the outer wall of the socket 2 has a plurality of evenly spaced telescopic grooves 21 inside the handle portion, and a locking component 3 is installed in the plurality of telescopic grooves 21. Specifically, the locking assembly 3 includes a plurality of locking pins 31 installed in the telescopic groove 21. The plurality of locking pins 31 extend and retract from the telescopic groove 21 into the locking hole 11. A push-pull ring 32 is fixed to the outside of the plurality of locking pins 31. The push-pull ring 32 moves vertically with the locking pins 31. Specifically, the unlocking component 4 includes an unlocking ring 41 disposed at the top of the locking hole 11, and a plurality of unlocking pins 42 installed at the bottom of the unlocking ring 41, which push the plurality of locking pins 31 out of the locking hole 11.

[0018] Specifically, the upper and lower ends of the locking hole 11 are provided with limiting rings 12, and the outer wall of the unlocking post 42 is provided with a limiting plate 43 that matches the limiting rings 12. The top of the unlocking post 42 and the top of the locking post 31 are both hemispherical.

[0019] Specifically, a limit buckle 22 is provided at the opening of the telescopic groove 21, and a stop block 33 is provided at the bottom of the locking post 31 to match the limit buckle 22. A locking spring 34 is fixed between the bottom of the locking post 31 and the bottom of the telescopic groove 21. One side of the telescopic groove 21 leads to the outside of the socket 2, and one side of the bottom of the locking post 31 extends and is fixed inside the push-pull ring 32.

[0020] Specifically, the push-pull ring 32 is fixed to the outer bottom of multiple locking posts 31, and the top of the push-pull ring 32 is provided with multiple anti-slip textures 35.

[0021] Specifically, when the plug 1 and the socket 2 are mated and locked, the locking hole 11 is exactly matched with the position of the locking pin 31, and the size of the locking pin 31 and the size of the unlocking pin 42 are matched with the locking hole 11.

[0022] Specifically, the length of the telescopic groove 21 is such that the locking pin 31 can enter the locking hole 11.

[0023] In this embodiment, multiple evenly spaced locking holes 11 are machined on the handle portion of the outer wall of the plug 1, and limiting rings 12 are fixed at the upper and lower ends of each locking hole 11. Unlocking pins 42 with limiting plates 43 on the outer wall and hemispherical tops are inserted into the locking holes 11 to ensure that the limiting plates 43 and the limiting rings 12 are compatible. Then, the tops of the multiple unlocking pins 42 are fixed together with the unlocking rings 41 to complete the assembly of the unlocking component 4 and the plug 1.

[0024] Specifically, multiple evenly spaced telescopic grooves 21 are machined on the handle part of the outer wall of the socket 2. A limit buckle 22 is fixed at the opening of each telescopic groove 21, and a locking spring 34 is fixed at the bottom of the groove. A locking post 31 with a stop block 33 at the bottom and a hemispherical top is installed into the telescopic groove 21, so that the stop block 33 matches the limit buckle 22, and the bottom of the locking post 31 is fixed to the top of the locking spring 34. Since one side of the telescopic groove 21 leads to the outside of the socket 2, the bottom side of multiple locking posts 31 is fixed together to the inside of the push-pull ring 32. At the same time, multiple anti-slip textures 35 are machined on the top of the push-pull ring 32 to complete the assembly of the locking component 3 and the socket 2.

[0025] Specifically, the handheld parts of the plug 1 and socket 2 are aligned with their axes and pushed towards each other. As the plug 1 and socket 2 gradually approach each other, the locking hole 11 and the locking pin 31 are precisely aligned. At this time, under the elastic force of the locking spring 34, the locking pin 31 extends out of the telescopic groove 21 and is embedded in the locking hole 11 to form a rigid lock and complete the docking.

[0026] Specifically, when separation is required, hold the plug 1 with one hand and push the unlocking ring 41 upward with the other hand, causing the unlocking pin 42 to move downward within the locking hole 11. The bottom of the unlocking pin 42 pushes the locking pin 31 to overcome the elasticity of the locking spring 34 and retract from the locking hole 11 into the telescopic groove 21. At the same time, you can hold the push-pull ring 32 to assist in pulling down the locking pin 31. After the locking pin 31 is completely disengaged from the locking hole 11, pull the plug 1 and the socket 2 in the opposite direction to achieve separation.

[0027] In this embodiment, during docking, the locking post 31 automatically embeds into the locking hole 11 by the elastic force of the locking spring 34, forming a rigid lock on the post hole, eliminating the need for the screwing operation of traditional threaded connections; and the locking post 31, the unlocking post 42 and the locking hole 11 are precisely matched in size, and can maintain a locked state in a vibration environment, effectively preventing the connector from accidentally falling off.

[0028] In this embodiment, the locking hole 11 and the telescopic groove 21 are both arranged in multiple evenly spaced groups. After multiple locking pins 31 are simultaneously embedded in the corresponding locking hole 11, they restrict the relative rotation of the plug 1 and the socket 2 from the circumferential direction, so as to avoid the inner conductor contact offset and the outer conductor shielding failure caused by the rotation, reduce signal reflection and insertion loss, and ensure the stability of high frequency signal transmission.

[0029] In this embodiment, the cooperation between the limiting ring 12 and the limiting plate 43, and the limiting buckle 22 and the stop block 33, respectively restricts the movement range of the unlocking post 42 and the locking post 31, preventing the components from detaching; the design of the unlocking ring 41 and the push-pull ring 32 simplifies the unlocking operation, and the anti-slip texture 35 of the push-pull ring 32 improves the operating feel and reduces the difficulty of separation.

[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.
