Description

Surge protector

Technical Field

The utility model relates to the technical field of surge protectors, in particular to a surge protector.

Background

The surge protector is installed on the electrical system in the lightning multiple-generation area, so that the lightning protection effect can be achieved, because the lightning is a spherical conductor, huge energy can be generated when the lightning invades into a circuit, if the surge protector is not installed at this time, electrical damage or personnel injury accidents are easily caused, and therefore the surge protector is required to be installed for protection.

The surge protector, also called lightning protector, is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines. When a peak current or voltage is suddenly generated in an electric loop or a communication line due to external interference, the surge protector can conduct shunt in a very short time, so that damage of the surge to other equipment in the loop is avoided.

The existing surge protector still has the following problems: when the surge protector is installed and wired, a wire pressing hole and a wire pressing screw are generally adopted to press and fix the wire head and realize the electric connection between the wire and the control board, however, because the wiring post is exposed outside the shell, the risks of electric leakage, electric shock, short circuit and the like are easy to occur to the wire head conductor parts of the screw and the wire, and when the surge protector is installed, the wire connection is required to be carried out by a plurality of screws, so that the connection installation efficiency is reduced; and the radiating effect of current surge protector itself is comparatively poor again, can't effectually distribute away the heat, will lead to the heat to pile up always in surge protector like this, and the effect that first uses will become poor, and second calls surge protector itself after generating heat can lead to inside components and parts to take place to damage, and holistic life can reduce, waste resource.

In view of this, we propose a surge protector.
