Abstract
Description
Technical Field
[0001] This invention relates to the field of radio frequency connector technology, and in particular to a novel radio frequency coaxial connector. Background Technology
[0002] Radio frequency (RF) coaxial connectors are components that are attached to cables or installed on instruments. As components that electrically connect or disconnect transmission lines, the main function of RF connectors is to realize signal transmission and connection.
[0003] Traditional plug-in RF coaxial connectors include a socket and a plug, such as Figure 1 As shown, the conductor 200 in the socket housing 100 typically has an expanded end structure. The conductor 200 is then press-fitted to the socket housing 100, as shown below. Figure 2 As shown; that is, multiple expansion grooves need to be evenly processed on the conductor 200 of the socket to fit tightly with the conductor of the plug, so that the outer wall of the conductor of the plug abuts against the inner wall of the conductor 200 of the socket to achieve electrical connection.
[0004] However, the traditional expansion joint structure of conductor 200 has the following drawbacks: the multi-groove structure and circumferential contact are prone to signal leakage, and the complex structure of conductor 200 has a complicated processing technology, resulting in high production costs. Summary of the Invention
[0005] The purpose of this invention is to provide a novel radio frequency coaxial connector to solve the problems existing in existing radio frequency connectors.
[0006] To address the aforementioned technical problems, this invention provides a novel radio frequency coaxial connector, comprising a radio frequency plug and a radio frequency socket; The radio frequency socket includes a housing, and an outer conductor of the socket is provided inside the housing. The outer conductor of the socket is connected to the outer conductor of the plug in the radio frequency plug. The outer conductor of the socket and the outer conductor of the plug are electrically connected through their end faces, and the RF plug and RF socket are locked and fixed by nuts, so that the end faces of the outer conductor of the socket and the outer conductor of the plug are tightly connected. The housing also includes a socket inner conductor, which is connected to the plug inner conductor in the radio frequency plug.
[0007] Preferably, the outer conductor of the socket is a cylindrical structure, and the outer conductor of the plug is machined with a contact step. When the outer conductor of the socket and the outer conductor of the plug are plugged into each other, an end face electrical connection is achieved at the step.
[0008] Preferably, the outer conductor of the socket and the outer shell are an integral structure.
[0009] Preferably, the outer conductor of the socket and the outer shell are separate structures.
[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the outer conductor of the socket is a cylindrical structure, and the outer conductor of the plug has a contact step machined inside. When the outer conductors of the socket and the plug are plugged into each other, an end-face electrical connection is achieved at the step. Compared with the traditional expansion groove outer conductor structure, it eliminates the need for multiple expansion grooves, reducing processing difficulty and cost, while also avoiding signal leakage problems caused by grooves. 2. In this invention, the outer conductor of the socket and the outer shell are an integral structure. Compared with the traditional expansion-type outer conductor structure, the manufacturing difficulty is reduced after the outer conductor structure is optimized, so the outer conductor of the socket and the outer shell can be designed as an integral structure. This optimizes the connection structure between the two, thereby further reducing the axial volume of the RF socket and meeting the miniaturization requirements of RF coaxial connectors.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0014] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0015] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0016] In addition, the features, operations, and characteristics described in the specification can be combined in any suitable manner to form various embodiments. Similarly, the steps or actions described in the method can be rearranged in a manner that is readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the purpose of clearly describing a particular embodiment and are not necessarily required orders, unless otherwise stated that a particular order must be followed. Example
[0017] This invention provides a novel radio frequency coaxial connector; please refer to [link / reference]. Figure 3 The device includes an RF plug and an RF socket. The RF socket includes a housing 1, and an outer conductor 2 is provided inside the housing 1. The outer conductor 2 is connected to the outer conductor 3 of the plug in the RF plug.
[0018] The socket outer conductor 2 and the plug outer conductor 3 are electrically connected through end face 10, and the RF plug and RF socket are locked and fixed by nut 4, so that the end face 10 of the socket outer conductor 2 and the plug outer conductor 3 are tightly connected; the housing 1 is also provided with a socket inner conductor 5, which is inserted into the plug inner conductor 6 in the RF plug.
[0019] Specifically, the socket outer conductor 2 has a cylindrical structure, and the plug outer conductor 3 has a contact step machined inside. When the socket outer conductor 2 and the plug outer conductor 3 are plugged into each other, the end face 10 is electrically connected at the step. Compared with the traditional expansion groove type outer conductor structure, it eliminates the need to open multiple expansion grooves, reducing processing difficulty and cost, while also avoiding signal leakage problems caused by grooves.
[0020] Furthermore, the outer conductor 2 of the socket and the outer shell 1 are an integral structure. Compared with the traditional expansion-type outer conductor structure, the processing difficulty is reduced after the outer conductor structure is optimized, so the outer conductor of the socket and the outer shell can be designed as an integral structure. This optimizes the connection structure between the two, thereby further reducing the axial volume of the RF socket and meeting the miniaturization requirements of RF coaxial connectors.
[0021] In another embodiment, such as Figure 4 and Figure 5 The outer conductor 2 of the socket and the outer shell 1 can also be separate structures, with the two being press-fitted together.
[0022] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
