A TV socket

Abstract

The invention discloses a television ferrule. The key points of the technical scheme are as follows: the television ferrule includes a ferrule shell and a ferrule center needle; there is an external threaded part in threaded connection with a locking nut on the lower part of the ferrule shell; the lower end of the external threaded portion is connected with a plugging part matching the locking nut; the plugging part is provided with a cable through hole matching a cable television line; an installation through hole communicated with the cable through hole is arranged in the center of the upperpart of the ferrule shell, and the ferrule center needle is arranged in the installation through hole by penetrating; the ferrule center needle is sleeved with an elastic ring matching the inner wallof the ferrule shell, a fixed seat and a protective sleeve in turn from top to bottom; the ferrule center needle includes a plug bush part and a wiring part which are integrally formed; the plug bushpart and the wiring part are respectively provided with a plug bush opening and a wiring opening; and the end of the wiring opening forms a closing-in structure by stamping. The television ferrule ofthe invention has the effects of simple structure, reliable wiring and good television signal.

Description

technical field [0001] The invention relates to the technical field of TV signal transmission components, in particular to a TV socket. Background technique [0002] Cable TV cables are widely used as connection cables for transmitting TV radio frequency signals between TV networks and TV equipment (such as TV sets, set-top boxes, recorders / players, etc.), generally including copper cores, insulating layers outside the copper cores, The shielding layer over the insulating layer and the protective layer (skin) over the shielding layer. Usually, the connection between the cable TV lines is realized by inserting the TV socket plug which can meet the requirements of TV signal transmission into the TV socket of the receiver. With the popularization of TV and the rapid development of networked TV signal transmission technology, the application of TV sockets is getting wider and wider, and its performance requirements are getting higher and higher. These performances mainly includ...

AI Technical Summary

Problems solved by technology

[0005] 1. The connection between the center pin and the copper core of the cable TV cable is not firm, and it is easy to loosen and fall off, resulting in poor TV signal and affecting the use of the TV;

[0006] 2. The structure of the TV insert is cumbersome, which reduces the disassembly efficiency between the TV insert and the cable TV line;

[0007] 3. The shielding layer of the cable TV cable is easy to loose, which leads to the deterioration of the TV signal and affects the use of the TV
