[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figures 1-3 The present invention provides an embodiment of a portable radio frequency coaxial connector, comprising a protective sleeve 1 and a base connection port 7. A connection port 9 is slidably connected to the inner wall of the protective sleeve 1, and a ball bearing 10 is slidably connected inside the connection port 9. One end of the ball bearing 10 is slidably connected inside the connection port 9, and the other end is slidably connected to the inner wall of the protective sleeve 1. A support ring 3 is fixedly connected to the inner wall of the protective sleeve 1, and a sealing ring 11 is fixedly connected to the outer wall of the support ring 3. A spring 12 is fixedly connected to one end of the sealing ring 11.

[0012] The connector 9 on the inner wall of the protective sleeve 1 can slide along the inner wall. One end of the ball bearing 10 inside the connector 9 moves synchronously with the connector 9, while the other end slides against the inner wall of the protective sleeve 1 to guide and limit its movement, ensuring the stability of the connector 9's movement. The support ring 3 fixed on the inner wall of the protective sleeve 1 provides installation support for the sealing ring 11. The spring 12 connected to one end of the sealing ring 11 is always in a pre-tight state. When the connectors are mated, the connector 9 is pushed by external force to move towards the support ring 3. The spring 12 is compressed, generating a reverse elastic force. Combined with the limiting effect of the ball bearing 10, the connector 9 is tightly fitted with the mating parts. At the same time, the sealing ring 11 fills the gaps to achieve a seal. Finally, through the linkage and elastic force of the mechanical structure, stable mating and sealing protection are achieved.

[0013] Reference Figures 1-3 One end of the support ring 3 is fixedly connected to a connecting sleeve 4, and one end of the connecting sleeve 4 is fixedly connected to a front end bayonet 5. Two first locking blocks 6 are fixedly connected to the outer wall of the front end bayonet 5, and two first locking blocks 14 are fixedly connected to the outer wall of the front end bayonet 5.

[0014] The connecting sleeve 4, which is fixed at one end of the support ring 3, provides a stable installation base for the front bayonet 5. The two first locking blocks 6 and the two first engaging blocks 14 on the outer wall of the front bayonet 5 are symmetrically distributed. When the connector is docked, the front bayonet 5 moves synchronously with the connecting sleeve 4. The first locking blocks 6 and the mating structure of the docking parts form a preliminary limit to prevent displacement during docking. At the same time, the first engaging blocks 14 and the corresponding engaging structures are precisely engaged. The front bayonet 5 and the docking parts are tightly fixed through mechanical engagement. With the support of the connecting sleeve 4 and the linkage of the overall structure, the structural stability of the connector after docking is further improved, avoiding loosening of the connection due to vibration or external force during use, and ensuring the continuity of signal transmission.

[0015] Reference Figures 1-3 The base connection port 7 is fixedly connected to a rear end bayonet 8. Two second bayonet blocks 15 are fixedly connected to the outer wall of the rear end bayonet 8, and two second bayonet blocks 16 are fixedly connected to the outer wall of the rear end bayonet 8.

[0016] The rear bayonet 8 at one end of the base connection port 7 serves as a key docking component. Its two second locking blocks 15 on the outer wall form a preliminary positioning with the docking structure, and the two second locking blocks 16 precisely engage with the corresponding locking structure. Through mechanical locking, a stable connection is achieved. In conjunction with the overall structure, it effectively resists vibration and external force, ensuring connection reliability and signal transmission stability.

[0017] Reference Figures 1-3 A cylinder 20 is fixedly connected to the inner wall of the connecting sleeve 4, and a thread 13 is provided on the outer wall of the cylinder 20.

[0018] The cylinder 20 fixed on the inner wall of the connecting sleeve 4 provides an installation carrier for the thread 13. The thread 13 engages with the matching thread of the mating part, and the connection tightness is enhanced by the helical tightening action. Together with the overall structure, it achieves double fixation and further improves the connection stability.

[0019] Reference Figures 1-3 The bottom of the protective cover 1 is fixedly connected to a PTFE insulation layer 17, the bottom of the PTFE insulation layer 17 is fixedly connected to an ABS plastic roller 18, and the bottom of the ABS plastic roller 18 is fixedly connected to a TPU coating 19.

[0020] The PTFE insulation layer 17 at the bottom of the protective cover 1 provides insulation protection, the ABS plastic spool 18 provides structural support, and the TPU coating 19 enhances the protective performance, working together to ensure safety and stability during use.

[0021] Reference Figures 1-3 One end of the connecting sleeve 4 is fixedly connected to the interface 2.

[0022] The interface 2 at one end of the connecting sleeve 4 serves as a signal transmission carrier, precisely connecting to the adapter component to achieve stable transmission of radio frequency signals.

[0023] Working principle: The connecting port 9 on the inner wall of the protective sleeve 1 can slide along the inner wall. One end of the sliding ball 10 inside the connecting port 9 moves synchronously with the connecting port 9, while the other end slides against the inner wall of the protective sleeve 1 to achieve guiding and limiting, ensuring the stability of the moving process of the connecting port 9. The support ring 3 fixed on the inner wall of the protective sleeve 1 provides installation support for the sealing ring 11 and forms a stable connection structure with the connecting sleeve 4 fixed at one end. The interface 2 at one end of the connecting sleeve 4 serves as the core carrier for signal transmission, accurately aligning with the adapter component to ensure smooth signal transmission. The thread 13 on the outer wall of the cylinder 20 fixed on the inner wall of the connecting sleeve 4 engages with the adapter thread of the mating component to achieve spiral fastening. The two first locking blocks 6 and two first engaging blocks 14 on the outer wall of the front locking port 5 fixed at the other end of the connecting sleeve 4 precisely cooperate with the two second locking blocks 15 and two second engaging blocks 16 on the outer wall of the rear locking port 8 fixed at one end of the base connecting port 7, forming a double locking positioning. The spring 12, fixed at one end of the sealing ring 11, is always in a pre-tight state. During docking, it is compressed and generates a reverse elastic force, pushing the connector 9 to fit tightly with the docking parts. At the same time, the sealing ring 11 fills the gaps to achieve a seal and protection. The PTFE insulation layer 17, ABS plastic spool 18, and TPU coating 19 fixed at the bottom of the protective sleeve 1 work together to provide insulation, support, and protection. Through the coordinated operation of these structures, stable docking, sealing protection, and efficient signal transmission of the connector are achieved.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
