Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a housing structure for a 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 (CN222029376U) a programmable controller with a sliding modular mounting blade; this patent technology mainly protects the mounting structure between the connector body and the connector components, and does not disclose or claim protection for the controller's housing structure. This results in the following drawbacks in the existing housing structure: 1. The housing structure design is not simple and reasonable enough, making it inconvenient to quickly disassemble and assemble the housing, and the assembly between the various parts of the housing is not stable and reliable enough; 2. The inconvenience of quick disassembly and assembly between the various components inside the housing leads to poor stability after assembly; 3. The unreasonable installation and arrangement design between the various modules inside the housing results in poor heat dissipation.

[0004] Therefore, how to design a housing structure that is simpler and more reasonable, makes it easier to disassemble and assemble the outer shell and its internal components, and enables a more stable and reliable controller assembly has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to design a housing structure that is simpler and more reasonable in structure, makes it easier to disassemble and assemble the housing and the various components inside the housing, and makes the assembly of the controller more stable and reliable.

[0006] To achieve the above objectives, this utility model provides a controller housing structure, including a connector body and a connector assembly detachably mounted on top of the connector body via an installation structure; the connector body includes a housing and a controller assembly mounted within the housing; characterized in that; the housing includes a rear housing with an overall rectangular box structure and an open front side, and a front cover with an overall rectangular box structure and an open rear side is provided at the open end of the rear housing; on the inner side of the side plates on both sides of the rear housing, there are first connecting blocks extending forward, and the outer front end of the first connecting blocks has a first snap-fit ​​protrusion; on the inner side of the bottom plate on the lower side of the rear housing, there are two pairs of second connecting blocks extending forward, and the outer front end of the second connecting blocks has a second snap-fit ​​protrusion; on the inner circumferential surface of the front cover, corresponding to the first and second snap-fit ​​protrusions, there are first and second slots extending through the wall thickness; and the first and second snap-fit ​​protrusions are respectively snapped into the first and second slots.

[0007] Thus, in the aforementioned controller housing structure, by setting the housing as a rear housing and a front cover, and by setting a first connecting block on the inner side of the side plates on both sides of the rear housing, and a pair of second connecting blocks on the inner side of the bottom plate on the lower side of the rear housing, and by setting a first snap-fit ​​protrusion and a second snap-fit ​​protrusion on the outer front end of the first and second connecting blocks; and by setting a first latch and a second latch on the inner circumferential surface of the front cover, so that the first snap-fit ​​protrusion and the second snap-fit ​​protrusion respectively snap into the first latch and the second latch, thereby detachably connecting the rear housing and the front cover together. The entire structural design is simpler and more reasonable, and it is easier to disassemble and assemble. Furthermore, the first and second connecting blocks can play a connecting and supporting role, and the first and second snap-fit ​​protrusions play a limiting role, making the assembly more stable and reliable.

[0008] Furthermore, the cross-sections of the first and second snap-fit ​​protrusions are designed with a triangular structure.

[0009] Furthermore, the inner edge of the front end face of the rear housing has a forward-protruding mating flange. This facilitates proper assembly and improves assembly stability.

[0022] This makes it easier to arrange the second control board and also makes it easier to install and arrange the wiring ports on the second control board.

[0023] Furthermore, a second mounting groove is provided on each of the two sides inside the outer casing, such that the two sides of the second control board are respectively inserted and fitted into the second mounting groove.

[0024] This makes it easier to disassemble and assemble the second control board.

[0025] Furthermore, the front end of the second control board has wiring ports including an SD card slot port and a USB port.

[0026] As an optimization, a U-shaped clearance notch is provided on the upper side plate on the upper side of the rear housing, so that the wiring port on the upper part of the second control board passes through the clearance notch and is used to connect to the connector assembly.

[0027] In this way, by setting a clearance notch, it is easier to connect the second control board to the connector assembly.
