Problems solved by technology

The above-mentioned low-frequency interference enters the set-top box from the radio frequency socket through the cable TV cable, then enters the TV through the video cable and audio cable, and finally feeds back to the ground wire of the TV's power socket, thereby generating interference on the video cable and audio cable. The voltage difference is increased, forming interference, and the audio and video signal level is low, the video is usually 1Vp-p, and the amplitude of the audio that can be clearly heard is usually below 100mVp-p, so a small low frequency interference will affect the audio and video The signal is interfering, affecting the quality of the TV picture and sound

Abstract

The invention relates to a multifunctional socket, which comprises a shell body, a plurality of jacks, a cover body and LED (Light-Emitting Diode) display lamps, wherein the jacks are fixedly arranged on the shell; the peripheries of the jacks are provided with bosses; the outer end faces of the bosses are 1.0-12 millimeters higher than the outer end faces of the jacks; the LED display lamps are correspondingly arranged on one side of each jack; the shell is made of an insulating material; a low-frequency isolating capacitor is arranged in the shell; and the cover body is movably connected with the shell. The socket provided by the invention has complete functions and high anti-jamming performance.

Description

technical field [0001] The invention relates to a socket, in particular to a multifunctional socket. Background technique [0002] As we all know, in the digitalization process of the cable TV network, it is necessary to install a cable TV receiver (set-top box) at the receiving end of the cable TV. The installation process is very simple. The connection structure of the TV after the set-top box is installed, the audio and video input of the TV is connected to the audio and video output of the set-top box through the video cable and audio respectively, and the set-top box is connected to the cable TV through the cable TV cable. The TV socket is connected to the radio frequency socket, and the power cord (three cores) of the TV is inserted into the three-pin power socket. In the process of installing a cable TV receiver, it was found that after installing a set-top box on some TVs, the image appeared distorted or diagonal stripes, and the sound was mixed with low-frequency h...
