Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] like Figure 1-7 As shown, this embodiment provides a radio frequency coaxial connector with stable connection, including a connecting female head 20, on which a matching connecting male head 10 is arranged;

[0029] The female connection head 20 is provided with a connecting sleeve 22, the male connection head 10 is provided with a mounting sleeve 11, the outer wall of the mounting sleeve 11 is provided with a threaded sleeve 12, the surface of the connecting sleeve 22 is provided with an external threaded wall 23, the inner wall of the threaded sleeve 12 is threadedly matched with the external threaded wall 23, two groups of locking components 30 are provided on the threaded sleeve 12, the threaded sleeve 12 is sleeved on the outer wall of the connecting sleeve 22, so that the locking component 30 is stuck on the female connection head 20 to lock the threaded sleeve 12.

[0030] In this embodiment, when the coaxial connector is connected, the installation sleeve 11 on the male connector 10 is extended into the inner wall of the connecting sleeve 22, and then the threaded sleeve 12 is sleeved on the outer wall of the connecting sleeve 22, and the threaded sleeve 12 is rotated to make the threaded sleeve 12 move on the connecting sleeve 22, driving the locking assembly 30 to move, and when the locking assembly 30 contacts the female connector 20, the threaded sleeve 12 is locked;

[0031] Through the threaded cooperation between the threaded sleeve 12 and the connecting sleeve 22, and the setting of the locking assembly 30, the position of the threaded sleeve 12 on the connecting sleeve 22 can be locked to prevent connection failure due to rotation or movement, and ensure that the connecting female head 20 and the connecting male head 10 are more stable during connection, and reduce the loose connection caused by vibration or external force, thereby effectively improving the stability between the connecting female head 20 and the connecting male head 10, and when the threaded sleeve 12 rotates, the locking assembly 30 can be used to increase the contact area, which is convenient for driving the threaded sleeve 12 to rotate, thereby improving the convenience of operation throughout the day.

[0032] Specifically, the female connector 20 is provided with a connecting socket 21 , and the male connector 10 is provided with a connecting pin 13 , and the connecting pin 13 is adapted to the connecting socket 21 .

[0033] Specifically, the outer diameter of the installation sleeve 11 is smaller than the inner diameter of the connecting sleeve 22 , and the installation sleeve 11 extends into the inner cavity of the connecting sleeve 22 , so that the threaded sleeve 12 is sleeved on the outer wall of the connecting sleeve 22 .

[0034] Specifically, a connecting circular plate 24 is disposed on the connecting sleeve 22 , and two groups of locking notches 25 are formed on the connecting circular plate 24 . The two groups of locking components 30 are respectively extended into the locking notches 25 to perform the locking process.

[0035] In this embodiment, when the locking assembly 30 is locked, the threaded sleeve 12 rotates on the outer wall of the connecting sleeve 22. When the threaded sleeve 12 moves to the connecting circular plate 24, the two sets of locking assemblies 30 are aligned with the locking notch 25, and then the locking assembly 30 extends into the locking notch 25 for locking.

[0036] Specifically, the outer wall of the threaded sleeve 12 is symmetrically provided with two groups of locking cavities 122, and the locking cavities 122 are provided with a toggle groove 121, and the locking cavities 122 are connected with the outside through the toggle groove 121;

[0037] The two groups of locking assemblies 30 are respectively disposed in the two groups of locking cavities 122 .

[0038] Specifically, the locking assembly 30 includes a locking plate 32 , which is slidably disposed in the locking cavity 122 . A locking hook 31 is disposed on the locking plate 32 , and the locking hook 31 is stuck in the locking notch 25 to perform a locking process on the threaded sleeve 12 .

[0039] In this embodiment, when locking, the threaded sleeve 12 first contacts the connecting circular plate 24, so that the locking assembly 30 is aligned with the locking notch 25, and then the locking plate 32 in the locking assembly 30 is pushed into the locking notch 25, and the locking process is completed by locking the locking hook 31 on the locking notch 25.

[0040] Specifically, a toggle rod 34 is provided on the locking plate 32. The toggle rod 34 is arranged in a toggle through groove 121, and the toggle rod 34 slides in the toggle through groove 121, so that the locking plate 32 slides in the locking cavity 122.

[0041] In this embodiment, through the cooperation between the toggle rod 34 and the toggle through groove 121, the displacement direction of the locking plate 32 can be guided, and at the same time, it is also convenient to drive the locking plate 32 to displace by the toggle rod 34.

[0042] Specifically, two groups of placement grooves 123 are symmetrically formed on the threaded sleeve 12. The two groups of placement grooves 123 are matched with the positions of the two locking cavities 122. A deformation groove 33 is formed on the locking plate 32, and the locking plate 32 is made of an elastic material.

[0043] In this embodiment, when the locking hook 31 is stuck in the locking notch 25, through the provided deformation groove 33, it is convenient for the locking plate 32 to bounce away from the connecting circular plate 24, so that the locking hook 31 can quickly be stuck into the locking notch 25.

[0044] Of course, in this case, the placement groove 123 is used to place the locking hook 31, and at the same time, it can also increase the contact area between the hand of the user and the threaded sleeve 12, facilitating the rotation of the threaded sleeve 12.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
