By installing the insulator 3 on the inner side of the outer conductor 1 and the center pin 2 on the inner side of the insulator 3, a stable coaxial structure is formed. The plug-in terminal 21 is installed on one end of the center pin 2, which is convenient for connection with the male head. At the same time, a sealing ring 24 made of silicone material is installed on the middle outer wall of the center pin 2, which forms a card slot 32 on the middle inner wall of the insulator 3, which not only enhances the sealing performance of the connector, but also ensures the stability of the internal structure. Such a design effectively reduces the plug-in force, making the use of the connector more convenient, and also improves the overall performance and service life of the connector.

[0022] In this embodiment, a mounting opening 11 is provided on one side of the outer conductor 1 , and one end of the insulator 3 is inserted from the mounting opening 11 , so as to facilitate the installation of the insulator 3 .

[0023] Specifically, a plug-in port 12 is provided on the other side of the outer conductor 1 , and the center pin 2 extends from one end of the insulator 3 and is located in the plug-in port 12 , so as to facilitate docking with a male connector.

[0024] Furthermore, a center needle channel 31 is provided inside the insulator 3 , and the main body of the center needle 2 is located in the center needle channel 31 , thereby ensuring that the main body of the center needle 2 is insulated.

[0025] Furthermore, a limiting convex ring 33 is provided at one end of the insulator 3, the diameter of the plug-in end 21 is smaller than the diameter of the center needle 2 body, and the plug-in end 21 passes through the center of the limiting convex ring 33 to ensure that the plug-in end 21 of the center needle 2 is limited.

[0026] Furthermore, a first notch 22 is provided on the side wall of the center needle 2 near the center needle channel 31, and a second notch 23 is provided on the outer wall of the plug-in end 21, so that the center needle 2 has a certain elasticity to facilitate plugging and unplugging operations.

[0027] Furthermore, the insulator 3 is a hollow cylindrical structure, and the inner wall of the insulator 3 fits with the outer wall of the center needle 2 to ensure good sealing of the outer wall of the center needle 2.

[0028] Furthermore, the inner side of the installation opening 11 fits against the outer wall of the insulator 3 , thereby ensuring good sealing of the outer wall of the insulator 3 .

[0029] When the female coaxial connector of the utility model that reduces the insertion and extraction force when plugging with the male head is used, first, one end of the insulator 3 is inserted from the installation opening 11 on one side of the outer conductor 1 to ensure that the insulator 3 and the outer conductor 1 are tightly matched. The insulator 3 is a hollow cylindrical structure, and its inner wall fits the outer wall of the center pin 2 to form a good seal. At the same time, the main part of the center pin 2 is located in the center pin channel 31 inside the insulator 3, ensuring that the main part of the center pin 2 is insulated.

[0030] The central outer wall of the center pin 2 is provided with a sealing ring 24 made of silicone material, which forms a snap fit with the card slot 32 on the central inner wall of the insulator 3, which not only enhances the sealing performance of the connector, but also ensures the stability of the internal structure. A plug-in end 21 is provided at one end of the center pin 2, the diameter of which is smaller than the diameter of the main body of the center pin 2, and passes through the center of the limiting convex ring 33 at one end of the insulator 3. Such a design ensures the limiting and stability of the plug-in end 21 of the center pin 2 during the plug-in and pull-out process.

[0031] In order to facilitate the plugging and unplugging operation, a first notch 22 is provided on the side wall of the center pin 2 near the center pin channel 31, and a second notch 23 is provided on the outer wall of the plug end 21. These notches make the center pin 2 have a certain elasticity, and can be flexibly deformed during the plugging and unplugging process, thereby reducing the plugging and unplugging force. When the male head is docked with the female coaxial connector, the center pin of the male head will be inserted into the plug interface 12 of the female coaxial connector and connected with the plug end 21 of the center pin 2 of the female coaxial connector. Since the design of the utility model makes the plugging and unplugging force less than 8N, the docking and plugging and unplugging processes are very convenient.

[0032] Through such a design, the female coaxial connector of the utility model not only achieves the technical effect of less than 8N plugging and unplugging force when plugging with the male head, but also improves the overall performance and service life of the connector. At the same time, its convenient use and good sealing performance also make it have a wide range of application prospects in the field of automotive connector technology.
