Problems solved by technology
[0009] The above connection and assembly process is not only inconvenient, time-consuming and laborious, but also easy to damage or even break the outer conductor of the cable, and the clamping effect is not ideal, resulting in unreliable connection
[0010] The search found that the Chinese patent application with application number 200720031690.2 discloses a quick-plug self-locking radio frequency connector, but analysis shows that its structure is not suitable for solving the above problems after transplantation

Embodiment 1
[0032] The quick coaxial radio frequency connector of this embodiment such as figure 2 As shown, the basic structure is as follows: the shell is composed of a front shell 5 and a rear shell 6 that are connected to each other by spiral screwing, and the inner conductor is as image 3 As shown, it consists of an inner conductor seat 3 with an outer thread matched with the inner thread of the cable core and an inner conductor head 2 with a socket 1 . One end of the inner conductor seat 3 adjacent to the inner conductor head has an insertion hole, and a small coil 8 is housed in the insertion hole. One end of the inner conductor head 2 adjacent to the inner conductor seat 3 is inserted into the insertion hole, and is electrically connected to the inner conductor seat through a small coil 8 . Such as figure 2 As shown, the inner conductor head 2 is covered with an insulator 4 positioned in the front housing 5 , so that the inner conductor is located in the front housing 5 throu...

The invention relates to a quick-installation coaxial radio-frequency connector and a quick installation method thereof, which belong to the technical field of communication transmission facilities. The connector comprises a front casing, a back casing and an inner conductor, wherein the front casing and the back casing are mutually screwed and connected by screw threads, and the inner conductor is positioned in the front casing by an insulator in an isolation way; an inner hole at one end of the back casing, which is far away from the front casing, is provided with a tapered orifice, and a wire clamp is arranged between a step of the front casing, which is adjacent to an inner casing, and the tapered orifice; one end of the wire clamp, which faces to the tapered orifice, is provided withan axial extension groove, and an elastic clamping jaw structure is formed; an inner hole at one end of the wire clamp, which faces to the front casing, is provided with a stop step and is provided with a C-shaped spring coil, the C-shaped spring coil supports against the stop step, and the section of the C-shaped spring coil is in an inward recess shape; and one end of the back casing, which is adjacent to the front casing, is provided with external screw threads, and the relative end of the front casing is provided with internal screw threads matched with the external screw threads. After the invention is adopted, the connection of the radio-frequency connector and a cable to be connected becomes simple and convenient. Moreover, because of keeping the original shape of an outer conductor, the invention can not cause damage to the outer conductor, so that the invention is more scientific and also has more reliable connection. Meanwhile, the self structure of the invention is also simplified.
Description
technical field [0001] The invention relates to an electrical signal connector, in particular to a quick-installation coaxial radio frequency connector and a quick-installation method thereof, belonging to the technical field of communication transmission facilities. Background technique [0002] There are many kinds of radio frequency connectors, and its basic function is to realize the reliable electrical connection between the inner shell and the outer shell and the core and outer conductor of the communication cable by means of its own connection structure, so as to further realize the plugging with the corresponding plugging device. [0003] For a long time, the steps of connecting an existing radio frequency connector and cable researched by the applicant are as follows: figure 1 a-e are shown: [0004] Step a, Trimming one end of the cable evenly, including removing burrs and flashes, and flattening the boss 1-1; [0005] Step b, peel off the insulating outer sheath...
