[0003] Coaxial connectors are an important type of connector. They have a roughly cylindrical outer contour structure and can be used to connect two coaxial cables. Coaxial connectors are widely used in audio and video signal transmission, wired communication signal transmission, and antenna signal transmission.

[0004] like Figure 1 As shown, in some prior art coaxial connectors, both the male end 10 and the female end 20 use an integrally formed pin terminal 30, so that after the coaxial connectors are mated, the pin terminals 30 in the male end 10 and the female end 20 are in rigid contact with each other.

[0005] In the coaxial connector of the above structure, since the pin terminals 30 of the male end 10 and the female end 20 are in rigid contact with each other, the pin terminals 30 are easily deformed, which leads to a series of problems such as poor contact and unstable signal transmission. In addition, the anti-vibration and anti-pulling performance are weak, and the pin terminals 30 may even become loose when the male end 10 and the female end 20 are not loose.

[0006] In summary, how to provide a coaxial connector with a terminal structure that has a reasonable mechanical structure and stable signal transmission has become an urgent problem to be solved. Utility Model Content

[0011] In the above technical solution, the first end terminal further includes a first tail portion; the first tail portion is connected to the other end of the terminal housing relative to the first contact head.

Specifically, the front end of the first contact head 122 is the small end, and the rear end is the large end. The rear end of the first contact head 122 It is accommodated in the terminal housing 121 and limited by the ribs at the opening of the terminal housing 121; one end of the elastic member 123 presses against the inner wall of the terminal housing 121, and the other end of the elastic member 123 presses against one end of the first contact head 122 located in the terminal housing 121, thereby providing elasticity for the first contact head 122; after the first end housing 11 of the first end component 1 and the second end housing 21 of the second end component 2 are plugged into each other: the first contact head 122 of the first end terminal 12 retreats along the axial direction of the terminal housing 121, and the elastic member 123 is compressed; in this way, after the first end housing 11 of the first end component 1 and the second end housing 21 of the second end component 2 are plugged into each other, the first end terminal 12 of the first end component 1 has an elastic retreat stroke.

[0028] Furthermore, the first end terminal 12 also includes a first tail portion 124, which is connected to the other end of the terminal housing 121 relative to the first contact head 122; in this embodiment, the first tail portion 124 is integrally formed at the other end of the terminal housing 121 relative to the first contact head 122; the first tail portion 124 is provided to facilitate connecting (for example, welding) the wire at the first end terminal 12.
