Pluggable intelligent controller

Abstract

The invention relates to a pluggable intelligent controller which comprises an intelligent controller base. An intelligent controller body is connected to the intelligent controller base. The pluggable intelligent controller is characterized in that a connection guidance module is arranged on the intelligent controller base, and a join structure is arranged at the position corresponding to the intelligent controller body. Meanwhile, auxiliary connecting pieces are arranged in the intelligent controller base, and through holes are formed in the positions corresponding to the intelligent controller body. When connection is carried out, the connecting guidance module is in mutual contacting connection with the joint structure, the through holes directly face the auxiliary connecting pieces, and screws are connected to the through holes. Thus, stable and effective connection of the connecting guidance module and the joint structure can be achieved. Meanwhile, integral tight connection is achieved through matching of the auxiliary connecting pieces. Furthermore, dead lock phenomenon cannot be generated after integral connection, when replacement is needed, especially when the intelligent controller needs to be replaced, stable opening is guaranteed, and a box body is not damaged.

Description

technical field [0001] The invention relates to a pluggable device, in particular to a pluggable intelligent controller. Background technique [0002] A low-voltage circuit breaker (formerly known as an automatic switch) is a switching device that can not only switch on and off the normal load current and overload current, but also switch on and off the short-circuit current. In addition to the control function in the circuit, the low-voltage circuit breaker also has certain protection functions, such as overload, short circuit, undervoltage and leakage protection. There are many classification methods for low-voltage circuit breakers. According to the category of use, there are selective type (the parameters of the protection device can be adjusted) and non-selective type (the parameters of the protection device cannot be adjusted). According to the arc extinguishing medium, there are air type and vacuum type (currently domestic mostly air type). Low-voltage frame circuit...

Problems solved by technology

[0003] However, there are many specifications of low-voltage circuit breakers, and the low-voltage circuit breakers and intelligent controllers are often manufactured separately and then assembled and used as required.

In actual assembly, too many auxiliary tools are required, which affects assembly efficiency

At the same time, it is easy to loosen or get stuck, which is not conducive to use and maintenance
