Connect-disconnect module and substrate for electrophoresis protector

Abstract

A pluggable module of a surge protector, including a shell, a plug, a rheostat, an overheating protector, an indicator and a spring, is characterized in that the shell includes a bottom cover, an intermediate body and a top cover; the bottom surface of the bottom cover is a plane, The front is open, and the top cover covers the front opening of the bottom cover to form a single-unit pluggable module; the front of the intermediate body is open, and the bottom surface can be fixed on the top of the bottom cover or on another intermediate body, and the top cover Cover the front opening of the intermediate body to form a pluggable module of multiple units. A base of a surge protector, including a shell, a clamp, a spring, a terminal block, a terminal block, screws, a terminal and a micro switch. The shell has a "U"-shaped opening whose size is the same as that of a pluggable module. Same size, also includes sockets, that match the plugs of the pluggable modules. A pluggable module into which a single unit or multiple units can be inserted.

Description

technical field [0001] The invention relates to a surge protector, in particular to a pluggable module and a base of the surge protector used at the power supply end of the low-voltage side. Background technique [0002] The surge protector installed on the power supply side of the low-voltage side (hereinafter referred to as SPD) is a commonly used low-voltage protection device. The national standard stipulates that the SPD should have functions such as a device that is disconnected from the power supply when it deteriorates, overheating protection, and deterioration indication. The width of the existing SPD is generally 18mm, the width of the base and the pluggable module are both 18mm, and only one pluggable module can be installed on a base, therefore, the adaptability to various sizes is not good enough, for example SPDs with a width of 27mm cannot be formed. At the same time, the alloy material used in the overheating protector in the prior art SPD has a large deviati...

AI Technical Summary

Problems solved by technology

The width of the existing SPD is generally 18mm, the width of the base and the pluggable module are both 18mm, and only one pluggable module can be installed on a base, therefore, the adaptability to various sizes is not good enough, for example Unable to compose 27mm wide SPD

At the same time, the alloy material used in the overheat protector in the prior art SPD has a large deviation in melting point, and contains toxic metals, which will pollute the environment when the alloy is melted

Another shortcoming of the existing SPD is that the flow capacity of the selected rheostat is not high enough
