Coaxial radio frequency cable interference shielding and enhancing structure

Abstract

The invention discloses a coaxial radio frequency cable interference shielding and enhancing structure, and relates to the technical field of radio frequency cables. The structure comprises two shielding and enhancing mechanisms which are in symmetrical sliding fit, and each shielding and enhancing mechanism is composed of an outer shielding assembly, a cable clamping assembly, a magnetic pushing assembly and an inner shielding assembly. The cable clamping assembly, the magnetic pushing assembly and the inner shielding assembly are all located in the outer shielding assembly, the cable clamping assembly is fixedly connected with the outer shielding assembly, and the magnetic pushing assembly and the cable clamping assembly are magnetically repellent; the inner shielding assembly is in sliding fit with the outer shielding assembly, and the inner shielding assembly and the cable clamping assembly are magnetically repellent. Through the design of the shielding and enhancing mechanisms, the cable clamping assembly, a positioning column and a clamping piece, and the shielding and enhancing mechanisms can be installed outside a coaxial radio frequency cable interface after butt joint, so that the signal radiation between the exterior and the interior of the shielding and enhancing mechanisms is effectively blocked, and then the interference shielding performance of the cable interface is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of radio frequency cables, in particular to a coaxial radio frequency cable interference shielding enhancement structure. Background technique [0002] With the rapid development of electronic communications and networks, the shielding performance of radio frequency cables connected inside or between electronic devices is becoming more and more important. When an electrical signal passes through the radio frequency coaxial cable, due to the antenna effect, the cable can both radiate and receive signals under the coupling effect, resulting in serious electromagnetic compatibility problems. Moreover, with the rapid increase of various electronic devices, the cable suffers from electromagnetic interference, which leads to the loss of data of electronic devices, the loss of function of devices and cables, and even the probability that the entire system will be paralyzed. [0003] However, the applicant of the p...

Problems solved by technology

[0004] The purpose of the present invention is to provide a coaxial radio frequency cable interference shielding enhancement structure, through the design of the positioning column, the clip, the outer shielding assembly, the cable clamping assembly, the magnetic pushing assembly, the inner shielding assembly and the driving and rotating assembly, the existing After some coaxial radio frequency cables are butt-connected and installed, the signal shielding at the cable interface is realized by certain means, but the general shielding effect is poor and it is easily affected by the environment. According to the size of the cable interface, the interference shielding range at the interface can be flexibly adjusted. The existing cable interface shielding device is generally installed on the radio frequency cable through screws, which not only greatly reduces the installation efficiency, but also is inconvenient to adjust the position of the cable interface shielding device on the cable. question
