Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, P1 is the input port of the external power supply and antenna signal. There are five wiring holes in total. P1-1 and P1-5 are the holes for the input pins of 220V mains power, and P1-2 and P1-4 are the holes for the grounding pins of the antenna signal. , P1-3 is the hole for the input pin of the antenna signal line. P2 is the output port for TV power supply and antenna signal. There are also five wiring holes. -3 is the hole for the output pin of the antenna signal line.

[0014] Relay J1 has two switches. The two ends of the first switch are respectively connected to the mains 220V input pin through hole P1-1 and the mains 220V output pin through P2-1. The two ends of the second switch are respectively connected to the mains 220V input pin. Pin hole P1-5 and mains 220V output pin hole P2-5. In addition...

Abstract

The invention discloses a television lightning protection device, which comprises an external power supply, an antenna signal input port, a television power supply, an antenna signal output port, a relay and a step-down rectifying and voltage stabilizing circuit, wherein the external power supply and the antenna signal input port are provided with two commercial power 220V input pin through holes, two antenna signal grounding pin through holes and an antenna signal line input pin through hole; the television power supply and the antenna signal output port are provided with two commercial power 220V output pin through holes, two antenna signal grounding pin through holes and one antenna signal output pin through hole; switches of the relay are connected with the commercial power 220V input pin through holes and the commercial power 220V output pin through holes; the antenna signal grounding pin through hole is short-circuited. According to the television lightning protection device, variable protection functions such as self-locking and self-releasing are realized by using a carving process of a circuit board and a circuit structure consisting of electronic elements, and a television can be prevented from being damaged suddenly by high voltages such as lightning.

Description

technical field [0001] The invention relates to a lightning protector, in particular to a lightning protector for a TV set. Background technique [0002] At present, it is a big problem to prevent TV sets from being attacked by lightning. Every summer, especially in the thunderstorm season, many TV sets are damaged by lightning. Contents of the invention [0003] Based on years of sample collection and analysis of TV sets damaged by lightning strikes, the applicant provides a lightning protector for TVs, which can solve the problem of TV sets being damaged by lightning strikes. [0004] Technical scheme of the present invention is as follows: [0005] A lightning protector for a TV, comprising an external power supply and an antenna signal input port, and a TV power supply and an antenna signal output port; the external power supply and the antenna signal input port have five wiring perforations, respectively, the first mains 220V input leads Foot hole, the second mains ...
