[0022] The utility model provides a board-end male coaxial connector with a shell fixed by a snap, such as Figure 1-Figure 3 As shown, the connector comprises a plastic housing 1, with an outer conductor 4 mounted on one end thereof, a center pin 3 mounted within the outer conductor 4, a clip 2 mounted on the bottom of the plastic housing 1, and a slot 43 provided on one side of the outer wall of the outer conductor 4. The clip 2 snaps into the interior of the plastic housing 1 from the bottom thereof and engages with the slot 43. One end of the outer conductor 4 snaps into a side opening of the plastic housing 1. This ingenious design achieves a secure connection and convenient assembly and disassembly between the various components of the connector. Specifically, the assembly structure of the plastic housing 1, outer conductor 4, and center pin 3 ensures the electrical stability and reliability of the connector. The snap-fit design of the clip 2 and the slot 43 on the outer conductor 4 greatly simplifies the installation and disassembly process of the connector, improving maintenance efficiency. Furthermore, the design of snapping one end of the outer conductor 4 into the side opening of the plastic housing 1 further enhances the structural strength of the connector, enabling it to maintain stable performance in various operating environments. In summary, the technical benefits of the present invention are primarily reflected in improving the ease of use, reliability, and maintenance efficiency of the connector.

[0023] In this embodiment, an insulator 31 is provided on the outer surface of the center needle 3 to provide a certain insulation effect.

[0024] Specifically, an opening is provided at the bottom of the plastic housing 1 near the buckle 2 , and the top of the buckle 2 passes through the opening and is clamped in the clamping slot 43 , so as to facilitate the installation and fixation of the buckle 2 .

[0025] Furthermore, a positioning sleeve 41 is installed at one end of the outer conductor 4. The positioning sleeve 41 is sleeved on the end of the center pin 3 to facilitate the insertion of the female connector when the center pin 3 is connected.

[0026] Furthermore, a conductor connection post 42 is installed at the bottom of the outer conductor 4 to facilitate external connection of the outer conductor 4 .

[0027] Furthermore, the buckle 2 includes a base plate 21, with columns 22 installed at both ends of the top of the base plate 21, and a hook 23 installed on the top of the column 22. The inner wall of the plastic shell 1 is provided with a limiting groove, and the hook 23 is clamped in the limiting groove, so that the buckle 2 is fixed and will not loosen.

[0028] Furthermore, the positioning sleeve 41 is a cylindrical structure, and a gap is provided between the outer wall of the positioning sleeve 41 and the inner wall of the plastic shell 1 , which has a certain isolation effect.
