[0024] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0025] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 and Figure 2 The first embodiment of this application discloses a high-power radio frequency connector, which includes a housing 10, a spring sheet 20, a crimping ring 30, and a plug assembly 40.

[0028] An annular groove 11 is provided inside the outer casing 10, and a V-shaped groove 12 is formed at the edge of the annular groove 11. The spring sheet 20 is located in the annular groove 11 of the outer casing 10, and its two sides abut against the V-shaped groove 12. The pressing ring 30 abuts against the two sides of the spring sheet 20 and is located in the V-shaped groove 12, so as to press the spring sheet 20 in the two V-shaped grooves 12, so that the spring sheet 20 is spread open, thereby giving the spring sheet 20 better holding force and fit, so as to facilitate the fit with the plug.

[0029] The insertion assembly 40 passes through the housing 10 and forms an insertion space 401 with the spring plate 20. Combined with the design of the crimp ring 30 and the V-groove 12, it effectively limits the movement of the spring plate 20, preventing it from falling out during insertion and removal, ensuring stable connector contact resistance, and improving service life and reliability. Specifically, the housing 10 is the foundational component of the entire connector, providing installation space and protection for other components. Two annular mounting slots 11 are arranged side-by-side on the inner side of the housing 10 to accommodate two spring tabs 20. The placement of the two spring tabs 20 increases the contact area of ​​the connector, thereby further reducing contact resistance and improving the connector's power transmission capability. Each annular mounting slot 11 has corresponding V-shaped grooves 12 along its two edges. This special V-shaped structure better mates with the spring tabs 20 and the crimping ring 30, ensuring that the spring tabs 20 do not detach, thus improving the reliability and stability of the connector.

[0030] The outer shell 10 can be made of metal, such as copper alloy, which has good conductivity and mechanical strength. Alternatively, other metals such as aluminum alloy can be used, as long as they meet the connector's requirements. The shape and size of the annular mounting groove 11 are designed according to the size and shape of the spring plate 20 to ensure that the spring plate 20 can be stably placed within it. The spring plate 20 is made of a metal material with good elasticity, giving it good elasticity and conductivity. The function of the spring plate 20 is to increase the contact area and reduce contact resistance. During insertion and extraction, the spring plate 20 undergoes elastic deformation to adapt to different insertion and extraction forces. The shape of the spring plate 20 is shown in the figure, but is not limited in this embodiment.

[0031] See Figure 2 and Figure 3 The crimping ring 30 abuts against both sides of the spring sheet 20 and is located in the V-groove 12. It presses the spring sheet 20 to keep its sides within the V-groove 12, thus preventing it from falling off during subsequent insertion or removal. The crimping ring 30 can be made of metal, such as stainless steel, which has high hardness and wear resistance. The crimping ring 30 is circular in shape and matches the V-groove 12, allowing it to press tightly against the spring sheet 20 and prevent it from loosening.

[0032] See Figure 2 and Figure 3 The plug-in assembly 40 includes a plug-in kit 41, an abutment member 42, a fixing member 43, and a contact member 44. The plug-in kit 41 is located inside the housing 10 and forms a plug-in space 401 with the spring sheet 20. The rear end of the plug-in kit 41 is provided with an outer protrusion 411 for abutting against an inner protrusion 101 inside the housing 10. See [link to relevant documentation]. Figure 4 The plug-in kit 41 may be made of insulating material to ensure electrical insulation performance. The design of the outward protrusion 411 can serve as a limit to prevent the plug-in kit 41 from moving axially within the housing 10.

[0033] See Figure 2 and Figure 3 One end of the abutment 42 is embedded in the outer shell 10 and abuts against one end of the outer protrusion 411 of the plug-in kit 41. At the same time, the end of the plug-in kit 41 away from the spring piece 20 is embedded in the abutment 42 and abuts against the abutment 42 through the outer protrusion 411. This ensures the connection stability between the plug-in kit 41 and the outer shell 10.

[0034] See also Figure 4The fastener 43 is sleeved on the abutment 42 and fixed to the inner side of the outer shell 10. Correspondingly, the fastener 43 is provided with an external thread 431, and the inner side of the outer shell 10 is provided with an internal thread 103 corresponding to the fastener 43. The fastener 43 is fixed to the outer shell 10 by means of threaded connection, so that the abutment 42 can stably abut against one end of the outer protrusion 411 of the plug-in kit 41.

[0035] See Figure 2 and Figure 3 The contact 44 passes through the plug-in kit 41 and the abutment 42. The plug-in kit 41 and the abutment 42 are respectively provided with through holes 412. The contact 44 is made of a metal material, such as a silver alloy, which has good conductivity and oxidation resistance. It is used to achieve electrical connection to transmit signals or power from one component to another. In this embodiment, the contact 44 and the through hole 412 are arranged in a one-to-one correspondence, with two contacts, thereby increasing the signal transmission channels and improving signal transmission efficiency.

[0036] See Figure 3 and Figure 4 A first limiting protrusion 421 is provided on the outer side of the abutment 42 near the plug-in kit 41. A limiting groove 102 is provided on the inner side of the housing 10 corresponding to the first limiting protrusion 421. When the two are assembled, the abutment 42 slides into the limiting groove 102 through the first limiting protrusion 421 and is assembled with the housing 10. After assembly, the position of the abutment 42 in the housing 10 can be effectively restricted, preventing the abutment 42 from rotating circumferentially and displacing axially, ensuring accurate docking and stable connection between the abutment 42 and the plug-in kit 41, thereby improving the structural stability and reliability of the entire high-power RF connector.

[0037] Additionally, see Figure 1 and Figure 3 A second limiting protrusion 104 is provided on the inner edge of the outer shell 10 to limit the rotation of the plug relative to the abutment 42, so as to ensure the stability and reliability of the connection between the connector and the plug. The shape of the second limiting protrusion 104 can be as shown in the figure, but is not limited here.

[0038] In addition, multiple fixing holes 105 are provided on the outer edge of the housing 10, through which screws or other through-holes can be inserted to fix the connector in place, so that the connector maintains a stable position during use and avoids its normal operation due to loosening or displacement, thereby improving the convenience of connector installation and the stability of use.

[0039] The implementation principle of this embodiment is as follows: the high-power RF connector uses the V-groove 12 and crimping ring 30 of the housing 10 to limit the spring contact 20, preventing it from falling off during repeated insertion and removal, ensuring stable contact resistance, and improving the connector's service life and reliability. Simultaneously, the rational design of the insertion assembly 40 makes the connector installation and use more convenient, and the tight fit between components enables effective transmission of high-power RF signals. This design represents a significant improvement over existing technologies, solving the spring contact detachment problem present in current high-power RF connectors and meeting the needs of fields such as communications, radar, and aerospace for high-power RF connectors.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
