Self-resetting communication line overvoltage protection box

Abstract

The invention provides a self-resetting communication line overvoltage protection box, belongs to the technical field of machinery and solves the problem that existing phone lines are unsafe. The self-resetting communication line overvoltage protection box comprises a base, a sliding cover and a voltage maintaining component, the sliding cover sleeves the base, the voltage maintaining component is mounted on the base, the voltage maintaining component comprises a wiring unit used for being connected with a phone line, and a grounding unit used for being connected with a grounding line, and a discharging tube used for receiving overvoltage of the wiring unit and discharging the same to the grounding unit is arranged between the wiring unit and the grounding unit. The self-resetting communication line overvoltage protection box has the advantage of capability of realizing overvoltage protection on the phone line.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a self-resetting communication line overvoltage protection box, in particular to a self-resetting communication line overvoltage protection box for overvoltage protection of telephone lines. Background technique [0002] When using electrical appliances, it is best to avoid the grid voltage being too high or too low. Whether it is industrial equipment or household appliances, there is a voltage allowable range. If it exceeds this range, the insulation strength and withstand voltage value of the electrical appliance will be exceeded, and the electrical appliance will heat up and break down. And burn out or even catch fire. [0003] At present, due to the theft of neutral wires, equipment aging, technical failures, human failures, natural disasters, power outages, and other reasons, the voltage is unstable and the voltage is too high or too low, resulting in a large number of burni...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the theft of neutral wires, equipment aging, technical failures, human failures, natural disasters, power outages, and power failures, etc., the voltage is unstable and the voltage is too high or too low, resulting in a large number of burning electrical appliances in large areas. Therefore, An electrical protector should be added to prevent electrical fires and protect the safety of life and property

[0004] Household wired telephones in daily life are connected to users by external communication cables, and then wired indoors through telephone lines. Telephones are often damaged due to overvoltage caused by lightning, and may even threaten the personal safety of users.
