The following will be described in detail with specific embodiments.

[0046] Embodiment 1

[0047] As Figures 1 to 6 shown, this embodiment discloses a radio frequency connector, comprising: a first connector 1, a second connector 2 and a connection component.

[0048] The first connector 1 includes a first pole 11 of the first connector, a second pole 12 of the first connector, and a first insulating filler 13. The first insulating filler 13 is used to fix the second pole 12 of the first connector within the first pole 11 of the first connector and to space apart the first pole 11 of the first connector from the second pole 12 of the first connector. The first pole 11 of the first connector is of an annular structure, and an external thread 111 is provided on its outer wall. A contact groove 121 is provided at the tail end of the second pole 12 of the first connector.

[0049] Combined Figure 4 As shown, the second connector 2 includes a first pole 21 of the second connector, a second pole 22 of the second connector, a second insulating filler 23, and a metal base 24. The first pole 21 of the second connector and the second pole 22 of the second connector are installed within the metal base 24. The second insulating filler 23 is used to fix the second pole 22 of the second connector within the first pole 21 of the second connector and to space apart the first pole 21 of the second connector from the second pole 22 of the second connector. The first pole 21 of the second connector and the metal base 24 are of an annular structure, and a limiting protrusion 3 is provided on the outer edge of the metal base 24. As Figure 5 shown, a first protrusion 4 for connecting to a wire and protruding outward is provided at the tail end of the metal base 24, and a second protrusion 5 for connecting to a wire and protruding outward is provided at the tail end of the second pole 22 of the second connector. The end of the second pole 22 of the second connector is provided as a plug 221 that is in contact and mating with the contact groove 121. In this embodiment, the plug 221 is conical and has an interference fit with the contact groove 121. The plug 221 is inserted into the contact groove 121, enabling electrical connection between the outer wall of the plug 221 and the inner wall of the contact groove 121.

[0050] In order to make the contact more stable, the end of the first pole 21 of the second connector is provided as an elastic contact structure. An insertion end 112 protruding outward is provided at the tail end of the first pole 11 of the first connector. The insertion end 112 is inserted and clamped onto the elastic contact structure, enabling electrical connection between the outer wall of the insertion end 112 and the elastic contact structure. The elastic contact structure can be provided as a spring piece with a constricted opening, a snap ring, a circlip, etc. It is installed on the metal base 24, electrically connected to the metal base 24 at one end and clamped to the insertion end 112 at the other end, thereby achieving stable electrical connection.

[0051] As Figure 4As shown, the elastic contact structure in this example is a snap ring 6. A plurality of grooves 61 are provided on the circumferential direction of the end of the snap ring 6, so that the snap ring 6 has a certain elastic deformation space. A guiding inclined surface 62 is provided at the front end of the inner wall of the snap ring 6 to guide the insertion end 112 to insert. When the insertion end 112 is inserted into the inner wall of the snap ring 6, the snap ring 6 is slightly expanded and deformed, so as to realize the pre-tight connection with the outer wall of the insertion end 112 and is not easy to loosen. In order to improve the reliability of the electrical connection, when the insertion end 112 is inserted and clamped on the elastic contact structure, the end surface 241 of the metal base 24 contacts the tail end surface 113 of the first pole 11 of the first connector, so as to realize the circumferential electrical connection between the outer wall of the insertion end 112 of the first pole 11 of the first connector and the first pole 21 of the second connector. At the same time, the tail end surface 113 of the first pole 11 of the first connector is electrically connected to the end surface 241 of the metal base. Such a connection makes the contact surface more, and even if part of the contact fails, it still does not affect the connection.

[0052] Combined with Figure 2 As shown, the connection component of this embodiment includes an inner shell 71 and an outer shell 72. The outer shell 72 is sleeved outside the inner shell 71. An internal thread 721 is provided on the inner wall of one end of the outer shell 72, and a first limiting portion 722 bent toward the center is provided at the other end of the outer shell 72. The inner shell 71 is sleeved outside the metal base 24, and one end of the inner shell 71 abuts against the limiting protrusion 3. A second limiting portion 711 bent toward the center is provided at the other end of the inner shell 71, and the second limiting portion 711 is clamped inside the first limiting portion 722. The setting of the inner shell 71 can not only play a role in tightly pressing the first connector 1 and the second connector 2, but also play a role in protecting the first protrusion 4 and the second protrusion 5. The outer shell 72 is made of metal material or non-metal material. When the outer shell 72 is made of metal material, an insulating sleeve ring is sleeved on the outer surface of the outer shell 72 or an insulating layer is coated.

[0053] During installation, first insert the first connector 1 and the second connector 2, then install the inner shell 71 and abut the inner shell 71 on the metal base 24, then install the outer shell 72. One end of the outer shell 72 is clamped on the inner shell 71, and then the internal thread 721 at the other end of the outer shell 72 is connected and locked with the external thread 111 on the outer wall of the first pole 11 of the first connector. Thus, the first connector 1 and the second connector 2 are tightly and reliably connected.

[0054] Embodiment 2

Then install the outer shell 72. One end of the outer shell 72 is clamped on the limiting step 712 in the middle of the inner shell 71. Then the internal thread 721 at the other end of the outer shell 72 is connected and locked with the external thread 111 on the outer wall of the first pole 11 of the first connector. Thus, a tight and reliable connection is achieved between the first connector 1 and the second connector 2.
