Distributed measuring and controlling node circuit package box

Abstract

The invention provides a distributed measuring and controlling node circuit package box. The distributed measuring and controlling node circuit package box comprises a main box body, a first end plate and a second end plate, wherein symmetric first slotted structures are formed in the upper inner surface and the lower inner surface of the front end of the main box body; symmetric second slotted structures are formed in the upper inner surface and the lower inner surface of the rear end of the main box body, wherein a distributed measuring and measuring node circuit is packaged in the main box body; the inner surface of the first end plate is provided with first buckle structures which are matched with the first slotted structures and is detachably connected with the main box body; the inner surface of the second end plate is provided with second buckle structures which are matched with the second slotted structures and is detachably connected with the main box body. The distributed measuring and controlling node circuit package box provides possibility for high-density distributed measuring and controlling node circuit package, not only can meet the circuit packaging demands of most of distributed measuring and controlling nodes, but also is especially suitable for the installation demand of the distributed measuring and controlling node circuit in an industrial control field with a narrow space.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a distributed measurement and control node circuit packaging box. Background technique [0002] Instrument modularization and module informatization are the development trend of modern instrument system design, and distributed measurement and control technology can just provide technical support for the realization of this idea. Distributed measurement and control is a system-level design technology for complex measurement and control objects. A distributed measurement and control system is usually composed of a number of measurement and control nodes with relatively independent functions and relatively dispersed spatial locations and physical links connecting these nodes. Each measurement and control node can form a measurement and control subsystem with relatively independent functions. Form a local measurement and control network. [0003] At present, all kinds o...

Problems solved by technology

[0003] At present, all kinds of circuit installation boxes on the market are not specially designed for the packaging of distributed measurement and control node circuits. They are large or small, have different shapes, and are complicated to install, which cannot meet the needs of the development of modern distributed measurement and control technology.

However, the screw hole fixing method of the conventional circuit packaging box has too high requirements on the hole position accuracy of the industrial field fixing parts, and it cannot be fine-tuned according to the actual wiring requirements of the I / O port of the distributed measurement and control node circuit, especially when installed in a narrow space. more difficult
