A combined PLC controller

Abstract

This utility model provides a combined PLC controller, belonging to the field of PLC controller technology. It includes a PLC controller body with a detachable protective shell on its outer side. Through the included wire-clamping assembly, the operator first installs the detachable protective shell and then performs wiring operations on one side of the PLC controller body. After wiring, the wire is passed through the wire divider frame. Then, by rotating the handle, the screw rotates, causing the moving clamp to move linearly along the screw's axial direction. As the handle continues to rotate, the moving clamp gradually moves closer to the fixed clamp on the inner wall of the wire divider frame until the wire is firmly clamped, thus securing the power cord. This design can flexibly adapt to wires of different thicknesses, and stable wire clamping can be achieved by reasonably adjusting the position of the moving clamp.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figure 1 As shown, this embodiment proposes a combined PLC controller, including a PLC controller body 1. A detachable protective shell 10 is provided on the outside of the PLC controller body 1. A wire clamping assembly 2 that can flexibly adapt to wires of different thicknesses is provided inside the detachable protective shell 10. A quick-release assembly 3 that facilitates wiring operations and maintenance by operators is provided on one side of the wire clamping assembly 2. like Figure 2 , Figure 3 and Figure 5 As shown, the cable clamping assembly 2 includes a base 201 fixedly connected to the inner bottom wall of the detachable protective shell 10. The base 201 is located on one side of the PLC controller body 1. A cable divider 202 is provided on the base 201. A screw 203 is provided on one side of the cable divider 202. A handle 204 is fixedly connected to one end of the screw 203. A movable clamp 205 is provided at the other end of the screw 203. The movable clamp 205 will move linearly along the axial direction of the screw 203. The movable clamp 205 is located inside the cable divider 202 and the handle 204 is located outside the cable divider 202. A fixing clamp 206 is fixedly connected to the inner side wall of the cable divider 202, which works with the movable clamp 205 to fix the cable. In use, the operator first installs the detachable protective shell 10, and then performs wiring operations on one side of the PLC controller body. After the wiring is completed, the wire is passed through the wire divider 202, and then the handle 204 is turned. The screw 203 will rotate accordingly, causing the moving clamp 205 to move linearly along the axial direction of the screw 203. As the handle 204 continues to rotate, the moving clamp 205 will gradually move closer to the fixing clamp 206 on the inner side wall of the wire divider 202 until the wire is tightly clamped, thereby fixing the power cord. It can flexibly adapt to wires of different thicknesses, and stable wire clamping can be achieved by reasonably adjusting the position of the moving clamp 205.

[0021] like Figure 3 and Figure 4 As shown, the quick-release assembly 3 includes a wiring module 301 that snaps onto one side of the PLC controller body 1. The wiring module 301 is located on one side of the wire divider frame 202. Multiple sets of sliding grooves 302 are provided on the base 201, allowing the wire divider frame 202 to slide within them. Each end of the multiple sets of sliding grooves 302 is snapped with a baffle 303, which is located on one side of the wire divider frame 202. In use, the wiring port is fixedly connected to the PLC controller body via spring-loaded pin contacts. The operator can slide open the baffle 303 and slide the wire divider frame 202 along the sliding grooves 302 on the base 201 to remove it from the base 201. At this point, the operator can further detach the wiring module 301 from the PLC controller body, thus enabling faster and more accurate wiring operations, significantly improving wiring efficiency. The operation is simple and convenient.

[0022] like Figure 3 and Figure 5 As shown, multiple sets of connection ports 4 are fixedly connected to the wiring module 301. The number of connection ports 4 corresponds one-to-one with the number of branch frames 202. Memory foam blocks 5 are fixedly connected to the inner sides of both the moving clip 205 and the fixed clip 206. When operators connect power cords and other cables to the connection ports 4, because the number of connection ports 4 corresponds one-to-one with the number of branch frames 202, the corresponding connection ports 4 and branch frames 202 can be quickly and accurately located during subsequent maintenance, repair, or cable replacement. The slow rebound characteristic of the memory foam blocks 5 allows them to adaptively deform according to the shape of the cables, better adapting to cables of different thicknesses and shapes.

[0023] like Figure 2 As shown, a magnetic door 6 is hinged to the top of the removable protective shell 10. The magnetic door 6 is located above the junction box 202, and a silicone sealing strip 7 is fixedly connected to the inner wall of the magnetic door 6. Operators can maintain the junction box 202 and its internal components simply by opening the magnetic door 6, without having to remove the entire removable protective shell 10. This greatly simplifies the maintenance process and reduces the number of operation steps and time. The sealing effect of the silicone sealing strip 7 can effectively prevent dust, moisture, etc. from entering the interior of the removable protective shell 10.

[0024] like Figure 3 and Figure 4 As shown, the base 201 has multiple sets of label slots 8, which are respectively set on one side of the splitter frame 202. Operators can place or paste labels with detailed information in the label slots 8 corresponding to the splitter frame 202 to facilitate subsequent equipment maintenance, repair, debugging or cable replacement and other operations.

[0025] like Figure 5As shown, the screw 203 passes through the wire divider frame 202 and is rotatably connected to the wire divider frame 202. The movable clamp 205 is rotatably connected to the screw 203 via a bearing. The movable clamp 205 is located inside the wire divider frame 202 and is rotatably connected to the screw 203 via a bearing, so that the rotational motion of the screw 203 can be converted into linear motion of the movable clamp 205 along the axial direction of the screw 203 through the bearing, which facilitates the fixing of the wire.

[0026] like Figure 1 and Figure 2 As shown, the side wall of the detachable protective shell 10 has multiple sets of heat dissipation slots 9, which are located on both sides of the PLC controller body 1. The PLC controller body 1 continuously generates heat during operation, and the hot air can be discharged from the heat dissipation slots 9 on both sides of the protective shell to prevent heat from accumulating inside the protective shell.

[0027] Specifically, when using this combined PLC controller: (e.g.) Figure 3 and Figure 4 As shown, the operator can slide open the baffle 303 and slide the wiring frame 202 along the groove 302 on the base 201 to remove the wiring frame 202 from the base 201. At this time, the operator can further detach the wiring module 301 from the PLC controller body, thereby performing the wiring operation more quickly and accurately. After the wiring is completed, as shown... Figure 2 , Figure 3 and Figure 5 As shown, the cable is passed through the splitter frame 202, and then the handle 204 is turned. The screw 203 will rotate accordingly, causing the movable clip 205 to move linearly along the axial direction of the screw 203. As the handle 204 continues to rotate, the movable clip 205 will gradually move closer to the fixed clip 206 on the inner wall of the splitter frame 202 until the cable is tightly locked. The slow rebound characteristic of the memory foam block 5 allows it to adapt to the shape of the cable and better adapt to cables of different thicknesses and shapes. The operator can maintain the splitter frame 202 and its internal components by simply opening the magnetic door 6 without removing the entire removable protective shell 10, which greatly simplifies the maintenance process and reduces the number of operation steps and time. The sealing effect of the silicone sealing strip 7 can effectively prevent dust, moisture and other substances from entering the interior of the removable protective shell 10.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
