Problems solved by technology

This small isolating switch has the following disadvantages: when the product breaks down and needs to be repaired or replaced, the power supply must be disconnected at first, then the wires should be removed, the product should be removed from the external clamping rail, a new product should be installed, and then wiring should be done. Plug in the power supply
During this maintenance process, the line power supply is discontinuous and the power outage time is long, especially not suitable for installation, removal and maintenance in industries such as data centers and communication power supplies that require continuity of power supply

Abstract

The invention discloses a base for a small isolation switch. The base comprises a plastic housing and two wiring terminal assemblies arranged in the plastic housing. The plastic housing comprises twowiring portions and a coupling portion, and a socket is formed by the two wiring portions and the coupling part. An external switch module is replaced by adopting a plug-and-pull structure, the plug-and-pull structure is unplugged from the base and then inserted into another one during the replacement and repair, and a power-off time is effectively shortened.

Description

technical field [0001] The invention belongs to the technical field of isolating switches, and in particular relates to a base for small isolating switches. Background technique [0002] The isolating switch is one of the most widely used electrical appliances in complete sets of devices such as power distribution meter boxes and power distribution systems, and it plays a role of power isolation in the circuit. [0003] Patent document CN206370368U discloses a specific structure of a small isolating switch. Its working principle and structure are relatively simple, and its performance is relatively stable and reliable. This small isolating switch has the following disadvantages: when the product breaks down and needs to be repaired or replaced, the power supply must be disconnected at first, then the wires should be removed, the product should be removed from the external clamping rail, a new product should be installed, and then wiring should be done. Plug in the power sup...
