PLC controller which is convenient to assemble

Abstract

The invention discloses a PLC controller which is convenient to assemble, and the PLC controller includes an upper frame seat and a lower frame seat. The lower end surface of the upper frame seat is provided with an installation groove I, and the interior of the installation groove I is provided with a wiring board I in a matched manner. The bottom of the installation groove I is provided with aninstallation groove II, and the interior of the installation groove II is provided with a wiring board II in a matched manner. The installation groove I, the installation groove II, the installation groove III and an installation groove IV are employed for achieving the positioning of between the wiring boards I and II and the upper and lower frame seats, and a pressing device is used for rotatingpressing. The entire positioning structure is relatively simple and is easy to assemble, and the positioning area is large, so that the components inside the entire PLC controller are installed stably. A rotating pressing mode is employed between the pressing device and the wiring boards I and II. An elastic pressing head in the pressing device is attached to the upper end surfaces of the wiringboards I and II. When the entire PLC controller vibrates, the elastic pressing head and a compression spring can achieve a better damping effect.

Description

Technical field [0001] The invention relates to the technical field of controllers, in particular to a PLC controller that is easy to assemble. Background technique [0002] PLC controller is the abbreviation of Programmable Logic Controller. It is an electronic system operated by digital operations, specially designed for applications in industrial environments. It uses a type of programmable memory for its internal storage of programs, executes logic operations, sequence control, timing, counting and arithmetic operations and other user-oriented instructions, and controls various types of machinery through digital or analog input / output Or the production process. As the core part of industrial control, it is used as a common control component in many automatic control agencies, but it still has the following drawbacks in actual use: [0003] 1. The installation method between the wiring board and the housing on the PLC controller is usually bolted. When the bolt and the install...

AI Technical Summary

Problems solved by technology

[0003] 1. The installation method between the wiring board and the housing on the PLC controller is usually bolt connection. When the bolts are tightened with the installation housing, the wiring board will be pressed tightly, but the tightening force is not easy to control, and the bolts and wiring The contact area between the boards is small, and it is easy to crush the wiring board if too much force is applied;

[0004] 2. The way of bolt connection is poor in shock resistance, and the components inside the shell are easily damaged by shock when the shell is vibrated;

[0005] 3. When using multi-point bolt connection, holes must be drilled on the terminal board, which will destroy the overall strength of the terminal board and cause the terminal board to be more easily broken
