Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein. Furthermore, it should be noted that the terms "front", "back", "upper side", "lower side" and the like used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from the geometric center of a specific part, respectively, and those skilled in the art should not understand that the technology beyond the scope of the present application is simply, without inventive adjustment. It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the actual protection. Well-known manufacturing methods, control procedures, component dimensions, material compositions, pipe arrangements, etc., have not been described in detail since they are readily understood by those of ordinary skill in the art, in order to avoid obscuring the present invention.

Fig. 1 is a perspective view of an embodiment of the present invention, fig. 2 is an exploded view of the embodiment of the present invention, and referring to fig. 1 and 2, an embodiment of the present invention provides an easy-to-fix coaxial connector including an outer conductor 100, and an insulator 200 and an inner conductor 300 are disposed in the outer conductor 100. The insulator 200 is used to separate the outer conductor 100 from the inner conductor 300, and to prevent conduction between the outer conductor 100 and the inner conductor 300.

The front and rear ends of the outer conductor 100 are connected to the front end connector 110 and the rear end connector 120, respectively. The working principle of the specific coaxial connector can refer to the existing radio frequency coaxial SMA connector.

A removable insert 400 is disposed on the outer side wall of the outer conductor 100. The insert 400 is used for fixing the direction of the coaxial connector, realizing the axial and radial limiting effects after the coaxial connector is connected with the outer cover, and preventing the phenomenon of rotation dislocation after the coaxial connector is matched with the outer cover, so that one coaxial connector can be applied to terminal antennas of more types and different shapes, namely one end is multipurpose.

Reference will now be made in detail to some embodiments, wherein "an embodiment" is referred to herein as a particular feature, structure, or characteristic that may be included in at least one implementation of the present application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
