PLC controller is based on a microprocessor and integrates computer technology, automatic control technology and communication technology. It can perform operations such as logic operations, sequential control, timing, counting and arithmetic operations. It controls various types of machinery or production processes through digital or analog input and output.

[0003] The patent with the patent authorization publication number CN220553655U particularly relates to a PLC controller that is easy to wire, including a PLC controller body, a plurality of plug-in parts arranged on the PLC controller body, and plug-in terminals for plugging. Although the above patent, through the setting of the connection component and the limit component, directly inserts the plug-in terminal into the inside of the plug-in part to complete the connection and fixation of the plug-in terminal, it is convenient and quick to use, but when installing the PLC controller, the bolt must first be inserted into the installation hole, and then the bolt must be tightened with a tool to install the PLC controller body. The operation process is relatively cumbersome, time-consuming and labor-intensive, so it cannot be installed quickly, and it is not convenient to disassemble, which affects later maintenance.

[0004] Therefore, a snap-on PLC controller is needed, which is provided with a mounting tube, a clamping plate and a limit frame, so as to achieve the purpose of easy and quick installation. Utility Model Content

When the PLC controller body 1 needs to be repaired, the pressure rod 8 is rotated upward so that it does not squeeze the card plate 5, and the first elastic member 7 returns to its original state, driving the card plate 5 to move to the side close to each other and disengage from the inner wall, and the PLC controller body 1 can be disassembled.

[0028] When the PLC controller is needed, move the PLC controller body 1 to the appropriate position of the control cabinet, insert the mounting tube 4 into the mounting hole in the control cabinet, and then turn the pressure rod 8 downward to make the pressure rod 8 squeeze the card plate 5 to move away from each other, so that the card plate 5 is engaged with the inner wall of the mounting hole, and the PLC controller body 1 is fixed on the control cabinet, so that there is no need to use additional tools to fix the PLC controller body 1, so as to achieve the purpose of facilitating and quickly installing. After fixing the PLC controller body 1, connect the power cord, sensor line and communication line to the connecting socket 3 according to the markings. After the wiring is completed, check whether the wiring is correct and then turn on the PLC controller body 1.

[0029] Example 2: Based on Example 1, please refer to Figure 1 , Figure 4 and Figure 5 A plurality of protrusions 10 are fixedly connected to the connecting seat 3, a card rod 9 is slidably arranged in the protrusion 10, and the card rod 9 can rotate.

[0030] Before using the PLC controller, according to the markings on the connecting socket 3, insert the power cord, sensor line and communication line into the wire plug hole of the connecting socket 3 in turn, rotate the clamping rod 9 180 degrees, the clamping rod 9 squeezes the clamping ball 12 to move to the side close to each other, and the second elastic member 13 is compressed accordingly, and then push the clamping rod 9 downward to squeeze the power cord, and the second elastic member 13 returns to its original shape to make the clamping ball 12 move to the side away from each other and clamp into the clamping groove 14 to fix the clamping rod 9, thereby completing the wiring, so there is no need to use bolts to fix, the operation is simple and labor-saving, and the wiring speed is increased.

[0031] See also Figure 1 and Figure 6 The left and right sides of the PLC controller body 1 are provided with mounting frames 1401 by means of bolt connection, two mounting plates 15 are provided in the mounting frame 1401 by means of bolt connection, a fan 16 for heat dissipation is provided on the mounting plate 15 by means of bolt connection, and a protective net 22 is embedded in the mounting frame 1401 to protect the fan 16, thereby preventing foreign objects from being drawn into the fan 16 when the fan 16 is running.

[0032] The PLC controller generates heat when it is running. Turn on the fan 16, and the fan 16 will generate wind force, thereby accelerating the air circulation inside the PLC controller, thereby dissipating the heat of the PLC controller and preventing the PLC controller from being overheated and affecting normal use. After the heat dissipation is completed, turn off the fan 16.

[0033] See also Figure 1 and Figure 7 A positioning rod 17 is fixedly connected to the right side of the top of the PLC controller body 1, and guide rods 18 are fixedly connected to both ends of the positioning rod 17. A cleaning block 19 is slidably arranged on the two guide rods 18. The cleaning block 19 is made of sponge, and the sponge is soft in texture to avoid scratching the control panel 2. The cleaning block 19 can contact the control panel 2. A third elastic member 20 for resetting the cleaning block 19 is sleeved on the front guide rod 18. A protective cover 21 is sleeved on the front guide rod 18. The third elastic member 20 is located in the protective cover 21 to protect the third elastic member 20, thereby preventing foreign matter from being entangled on the third elastic member 20.

[0034] After using the PLC controller for a long time, dust and other impurities will adhere to the control panel 2. Push the cleaning block 19 to the right, and the third elastic member 20 will be compressed, so that the cleaning block 19 wipes the control panel 2, thereby keeping the control panel 2 clean and avoiding affecting the reading of data. After wiping is completed, release the cleaning block 19, and the third elastic member 20 returns to its original shape, causing the cleaning block 19 to move to the left and reset.
