Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a combined housing structure for a programmable controller. Background Technology

[0002] A controller is a device that adjusts and manages a controlled object according to a preset program or input signal. It is widely used in many fields such as industry, transportation, and networks.

[0003] The applicant previously applied for patent (CN221598387U) for a programmable controller with flexible installation. This patent primarily protects the ability to detachably mount a mounting component at one end of the controller body, allowing the controller body to be assembled and fixed with external components, thus facilitating installation. However, the aforementioned patent structure does not disclose the composition of the controller housing or the connection relationships between its various parts. Furthermore, existing controller housing structures still suffer from the following problems: 1. The connections between the various parts of the housing are not stable and reliable enough, making assembly and positioning inconvenient; 2. The housing lacks heat dissipation holes, forcing the heat generated to rely primarily on a heat sink for cooling, resulting in inadequate heat dissipation.

[0004] Therefore, how to design a modular housing structure for a programmable controller with a simpler and more reasonable structural design, more stable and reliable connections between the various parts of the housing, easier assembly and positioning, and improved heat dissipation has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a modular housing structure for a programmable controller, comprising a housing with an overall flat rectangular box structure and an open top. A heat dissipation cover is provided at the open position of the housing. A control board is installed below the heat dissipation cover inside the housing, such that the wiring ports on the control board are inserted into mating openings on the front end face of the housing. The housing includes a base plate, with a front cover plate and a rear surround plate at each end. The two ends of the front cover plate are bent backward to form mating flanges. The rear surround plate is bent into a U-shape and its two ends are connected to the mating flanges. Each side and the middle of the surround plate has a first connecting block that is attached to and supported on the base plate and is detachably connected to the base plate. Each end of the surround plate has a second connecting block that extends forward and is attached to the inner side of the mating flange, and the second connecting block is detachably connected to the mating flange. A third connecting block extends downward and is attached to the inner side of the surround plate on the heat dissipation cover plate, and the third connecting block is detachably connected to the surround plate.

[0007] Thus, in the aforementioned shell structure, the shell is assembled from a bottom plate, a front cover plate, and a rear panel.
