Description

Technical Field

[0001] This utility model relates to a PLC control cabinet that is easy to install and wire, and belongs to the technical field of PLC control cabinets. Background Technology

[0002] For example, a PLC control cabinet disclosed in application number 202411403969.3 includes a cabinet body with a cabinet door movably connected to the front side of the cabinet body. A downward-sloping heat dissipation groove is provided on the left wall of the cabinet body. A humidity sensor is fixedly installed on the left wall of the cabinet body's inner cavity. A desiccant cylinder is fixedly connected to the left wall of the cabinet body's inner cavity. A sealing cap is threaded to the top of the desiccant cylinder. A material guiding assembly is provided inside the desiccant cylinder. A sealing cover is fixedly connected to the bottom of the desiccant cylinder. When the valve disc intermittently picks up and releases the desiccant, the desiccant cylinder remains relatively sealed, thus preventing the desiccant from becoming damp and ineffective. In conjunction with the humidity sensor controlling the valve plate to adjust the material hopper space in the valve disc, the amount of desiccant can be adjusted at different stages of dehumidification, ensuring reasonable desiccant usage and avoiding waste. Furthermore, it provides good air circulation and drying effect. At the end of drying, the ineffective desiccant automatically falls into a collection cylinder for easy recycling.

[0003] Based on our retrieval and analysis, we conclude that existing technologies still have shortcomings:

[0004] Existing technology requires opening the entire cabinet for wiring during use, and the wiring is messy. Therefore, there is a need for a PLC control cabinet that is easy to install and wire, and to improve upon the above shortcomings. Utility Model Content

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-3 As shown, this embodiment provides a PLC control cabinet that is easy to install and wire, including a PLC control cabinet 1;

[0023] The PLC control cabinet 1 has wire through holes 102 distributed on it, and a locking sleeve 2 is distributed on the outside of the PLC control cabinet 1. A cover 201 is locked onto the locking sleeve 2.

[0024] The card sleeve 2 and the PLC control cabinet 1 are interconnected.

[0025] The cover 201 is engaged with the locking sleeve 2.

[0026] Electrical mounting components 202 are distributed on the inner side of the PLC control cabinet 1.

[0027] The sealing plate 101 folds open and closes along the PLC control cabinet 1.

[0028] The electrical mounting component 202 on the PLC control cabinet 1 is a protruding structure.

[0029] like Figures 1-3 As shown in the figure, the working process of a PLC control cabinet that is easy to install and wire is as follows:

[0030] Step 1: Open the cover plate 101, flip the cover plate 101 around the hinge to the right, fully open the front of the cabinet, reveal the internal space of the cabinet corresponding to the electrical installation parts 202 and the wire through hole 102. According to the wiring requirements, determine the position where the wire needs to be connected, select the corresponding snap-fit ​​sleeve 2 on the outside of the cabinet, remove the cover 201 of the snap-fit ​​sleeve 2, and pull the cover outward to make the snap protrusion disengage from the slot.

[0031] The external wire is inserted through the opening end of the locking sleeve 2 and introduced into the cabinet through the wire through hole 102.

[0032] Since the snap-fit ​​sleeve 2 is connected to the inside of the cabinet, the wires can be directly extended to the electrical installation area inside the cabinet. PLC modules, terminal blocks, and other electrical components are installed on the electrical mounting component 202. For boss-type mounting components, screws are used to fix the components to the mounting holes of the boss; for rail-type mounting components, the component's clips are inserted into the rail and slid along the rail to the appropriate position for fixing.

[0033] Step 2: Connect the wires that pass through the cabinet to the electrical components, for example, by inserting the wire terminals into the wiring holes of the terminal block, or by tightening them to the wiring terminals of the PLC module;

[0034] Since the electrical mounting component 202 is a protruding structure, a certain space is formed between the electrical component and the cabinet wall after installation, which facilitates the arrangement of wires behind or on the side of the component, avoids direct contact between the wires and the cabinet wall, and leaves enough operating space for easy wiring. After the wiring is completed, the excess wires are bundled and organized inside the cabinet, so that the wires are neatly arranged along the edge of the cabinet wall or the electrical mounting component 202, avoiding messy tangling of the wires.

[0035] Step 3: Re-clamp the cover 201 onto the corresponding clamping sleeve 2, ensuring that the protrusion and the slot are fully engaged, sealing the opening of the clamping sleeve 2 to prevent dust, moisture, etc. from entering the cabinet. Flip the cover plate 101 to the left and attach it to the front of the cabinet. Secure the cover plate 101 with a latch or other locking device to complete the wiring and installation of the entire control cabinet. It is not necessary to open the entire cabinet. Only the cover 201 needs to be removed from the clamping sleeve 2 where wiring is required. The wires can be passed through from the outside of the cabinet to realize the wiring operation in a local area. This avoids the problem of dust entering and inconvenience caused by the traditional control cabinet requiring the entire cabinet door to be opened.

[0036] The protruding structure of the electrical installation component 202 provides an independent space for wire arrangement. Wires can be neatly arranged along the edge or back of the protruding structure. With the zoned setting of the snap sleeve 2, wires with different functions, such as power lines and signal lines, can be introduced from different snap sleeves 2 to achieve classification and organization and reduce wire crossing and confusion.

[0037] The snap-fit ​​connection between the cover 201 and the snap-fit ​​sleeve 2, as well as the folding and opening design of the cover plate 101, ensures the convenience of wiring while ensuring the overall sealing performance of the cabinet, effectively protecting the external environment from the influence of the internal electrical components of the cabinet.

[0038] Example

[0039] like Figures 1-3 As shown, open the cover plate 101, flip the cover plate 101 around the hinge to the right, fully open the front of the cabinet, reveal the internal space of the cabinet corresponding to the internal electrical installation component 202 and the wire through hole 102. According to the wiring requirements, determine the position where the wire needs to be connected, select the corresponding snap-fit ​​sleeve 2 on the outside of the cabinet, remove the cover 201 of the snap-fit ​​sleeve 2, and pull the cover outward to make the snap protrusion disengage from the slot.

[0040] External wires are inserted through the opening of the locking sleeve 2 and led into the cabinet through the wire through hole 102. Since the locking sleeve 2 is connected to the cabinet interior, the wires can extend directly to the electrical installation area inside the cabinet, where PLC modules, terminal blocks, and other electrical components are installed. For boss-type mounting components, screws are used to fix the components to the mounting holes of the boss; for rail-type mounting components, the component's clips are inserted into the rail, and it slides along the rail to a suitable position for fixation.

[0041] Connect the wires that pass through the cabinet to the electrical components, for example, by inserting the wire terminals into the wiring holes of the terminal block, or by tightening them to the wiring terminals of the PLC module;

[0042] Since the electrical mounting component 202 is a protruding structure, a certain space is formed between the electrical component and the cabinet wall after installation, which facilitates the arrangement of wires behind or on the side of the component, avoids direct contact between the wires and the cabinet wall, and leaves enough operating space for easy wiring. After the wiring is completed, the excess wires are bundled and organized inside the cabinet, so that the wires are neatly arranged along the edge of the cabinet wall or the electrical mounting component 202, avoiding messy tangling of the wires.

[0043] Re-clamp the cover 201 onto the corresponding clamping sleeve 2, ensuring that the protrusion and the slot are fully engaged, sealing the opening of the clamping sleeve 2 to prevent dust, moisture, etc. from entering the cabinet. Flip the cover plate 101 to the left and attach it to the front of the cabinet. Secure the cover plate 101 with a latch or other locking device to complete the wiring and installation of the entire control cabinet. There is no need to open the entire cabinet. Only the cover 201 needs to be removed from the clamping sleeve 2 where wiring is required. The wires can be threaded through the outside of the cabinet to achieve wiring operations in a local area. This avoids the problem of dust entering and inconvenience caused by the traditional control cabinet requiring the entire cabinet door to be opened.

[0044] The protruding structure of the electrical installation component 202 provides an independent space for wire arrangement. Wires can be neatly arranged along the edge or back of the protruding structure. With the zoned setting of the snap sleeve 2, wires with different functions, such as power lines and signal lines, can be introduced from different snap sleeves 2 to achieve classification and organization and reduce wire crossing and confusion.

[0045] The snap-fit ​​connection between the cover 201 and the snap-fit ​​sleeve 2, as well as the folding and opening design of the cover plate 101, ensures the convenience of wiring while ensuring the overall sealing performance of the cabinet, effectively protecting the external environment from the influence of the internal electrical components of the cabinet.

[0046] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
