[0027] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0028] By setting the entire plug as a straight-plug structure, the plug-in is stable and easy to operate to meet the usage requirements of different scenarios.

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0030] It should be noted that any directional indications in this application, such as front, back, left, right, up, down, front end, back end, left end, right end, upper, lower, left side, right side, longitudinal, transverse, axial, radial, front side, back side, etc., are all relative concepts.

[0031] like Figures 1 to 7 As shown, this is an embodiment of the present application:

[0032] A coaxial connector 100 includes a coaxial connector socket 3 and a plug 2 for mating, wherein the plug 2 includes: an outer conductor 21; an insulating rubber core 22 installed in the outer conductor 21; and a conductive terminal 23 embedded in the insulating rubber core 22; wherein the outer conductor 21 is a straight cylindrical structure as a whole, including a plug-in portion 211, a connecting base 212 formed by the plug-in portion 211 extending along the axial direction, and a first ring arm 213 and a second ring arm 214 formed by the connecting base 212 along the radial direction, wherein the inner diameter of the first ring arm 213 is smaller than the inner diameter of the second ring arm 214. The socket 3 includes an insulating body 32, a center conductor 33 fixed in the insulating body 32, and a metal shell 31. The plug 3 is detachably connected to the socket 2. When the plug 3 is connected to the socket 2, the outer conductor 21 on the plug 2 is mechanically and electrically connected to the metal shell 31 on the socket 3, and the conductive terminal 23 on the plug 2 is mechanically and electrically connected to the center conductor 33 on the socket 3. By setting the entire plug 2 as a straight-plug structure, the plugging is stable and easy to operate, so as to meet the usage requirements of different scenarios.

[0033] It is understandable that the first ring arm 213 is mounted on the outside 43 of the braided layer of the coaxial cable 4, and the second ring arm 214 is mounted on the outside 44 of the outer sheath layer of the coaxial cable 4. The insulating layer 42 of the coaxial cable 4 is exposed in the gap between the plug-in portion 211 and the first ring arm 213.

[0034] Furthermore, the insulating rubber core 22 is conical, and at least one lug 221 protruding outward is provided on the upper part of the conical shape. At least one recess 211A is provided on the side of the plug-in portion 211 close to the first ring arm 213, and a skirt 211B is provided along the circumference of the end of the plug-in portion 211 away from the first ring arm 213, and a contact protrusion 211C recessed inward is provided adjacent to the skirt 211B. The lug 221 can be fitted and clamped in the recess 211A to achieve the fixation between the insulating rubber core 22 and the outer conductor 21. The contact protrusion 211C is used to electrically contact with the metal shell 31 of the socket 3.

[0035] Furthermore, the conductive terminal 23 has a riveting end 231 and a contact end 232. The contact end 232 is in a petal shape and is sleeved on the outside of the central conductor 33 on the socket 3. The core wire 41 of the coaxial cable 4 is riveted inside the riveting end 231. Figure 7 As shown, the contact end 232 is configured in a petal shape, and the number of petals is preferably 3. The three petals enclose a cylindrical structure, and when the central conductor 33 of the socket 3 is higher, there is a suitable scraping distance.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
