[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 8 As shown, a plug-in connection PLC controller provided by an embodiment of the utility model includes:

[0034] The shell 1 includes a lower shell 101 and an upper shell 102. The lower shell 101 and the upper shell 102 are connected to form the shell 1. The shell 1 is combined with the internal circuit board 14 to form a PLC controller body. The PLC controller body is a digital operation controller for automatic control. The control instructions can be loaded into the memory at any time for storage and execution. The internal circuit board 14 stores instructions for executing operations such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output.

[0035] A placement groove 8 is provided on the side wall of the lower shell 101, and an internal circuit board 14 is arranged in the placement groove 8. Metal pins 12 are arranged on both sides of the lower surface of the internal circuit board 14. When the PLC controller is connected to the PCB circuit board, the surface of the PCB circuit board is provided with plugging holes corresponding to the metal pins 12. Multiple groups of metal pins 12 are plugged into the plugging holes on the surface of the PCB circuit board, so that an electrical connection is generated between the PLC controller and the PCB circuit board, which facilitates the mutual transmission of data between the two through the metal pins 12 to complete the control between the devices, so as to solve the time-consuming and labor-intensive connection between the PLC controller and the PCB circuit board through wires. The electrical connection between the PLC controller and the PCB board can be completed without removing too many screws, and cumbersome wiring steps are no longer required, thereby improving the efficiency of rapid installation between the PLC controller and the PCB circuit board, thereby solving the problem of wrong line connection caused by too many connection lines.

[0036] The adapter plate 15 and the outer shell 1 are detachably connected to the surface of the adapter plate 15. Heat sinks 2 are arranged on both sides of the adapter plate 15. The heat sink 2 is closely attached to one side of the outer shell 1. The heat sink 2 is used to dissipate heat for the outer shell 1. The temperature of the inner circuit board 14 will rise after long-term operation, thereby transmitting the excessive temperature to the outer shell 1. Therefore, the heat sink 2 has the effect of lowering the temperature of the surface of the outer shell 1 and the inner circuit board 14. The adapter plate 15 has the effect of fixing the outer shell 1 and positioning the outer shell 1.

[0037] The four corners of the inner circuit board 14 are provided with fourth threaded holes 11 for threaded connection with the adapter plate 15 . The inner circuit board 14 can be fixed in the placement groove 8 on the housing 1 by threaded connection of bolts with the adapter plate 15 and the inner circuit board 14 .

[0038] A third threaded hole 10 is provided at each of the four corners of the bottom of the placement slot 8, and the third threaded hole 10 passes through the upper surface of the lower shell 101. Four groups of third threaded holes 10 are arranged corresponding to the fourth threaded hole 11. Needle grooves 17 are provided on both sides of the bottom of the placement slot 8 for passing the metal pin 12. First, the bolt is passed through the second threaded hole 6 on the adapter plate 15, and then through the third threaded hole 10, and finally threadedly connected with the fourth threaded hole 11 on the internal circuit board 14. After the threaded connection is completed, the internal circuit board 14 can be fixed in the placement slot 8.

[0039] Four groups of second threaded holes 6 corresponding to the third threaded holes 10 are provided on the surface of the adapter plate 15 for threaded connection with the internal circuit board 14. Fixing holes 7 are provided at the four corners of the upper surface of the adapter plate 15. Notches 16 are provided on both sides of the upper surface of the adapter plate 15 for passing the metal pins 12. When the metal pins 12 are plugged into the PCB circuit, the adapter plate 15 is screwed to the PCB circuit board through the fixing holes 7 to ensure that the metal pins 12 are tightly plugged into the plug-in holes of the PCB circuit board, thereby ensuring a tight connection between the PLC controller and the PCB circuit board and facilitating data transmission between them.

[0040] A wire passing hole 9 is provided on the side wall of the heat sink 2, and the wire passing hole 9 is arranged corresponding to the placement groove 8. The housing 1 is located between the two groups of heat sinks 2. Multiple groups of wire management blocks 3 are fixedly installed on the side wall of the heat sink 2 from left to right. Multiple groups of wire management holes 13 are provided on the side wall of the wire management block 3 from left to right, and the wire management holes 13 are arranged corresponding to the wire passing holes 9. The wire passing holes 9 and the wire management holes 13 provide a backup solution for threading wires through the two groups of holes in different situations.

[0041] A square hole is provided at one end of the side wall of the heat sink 2, and ears 4 are fixedly installed on both sides of the lower shell 101. One end of the ear 4 passes through the square hole, and a first threaded hole 5 is provided at one end of the upper surface of the ear 4. When the PLC controller is not electrically connected to the PCB circuit board, the first threaded hole 5 on the ear 4 is used to enable the shell 1 to be threadedly connected to the machine and fixed without the adapter plate 15. In this way, even without the adapter plate 15, the PLC controller body can run stably on the machine, and it is convenient to make plug-in connections between wires or metal pins 12 with other devices, thereby increasing the scope of use of the PLC controller.

[0042] The upper shell 102 has four corners on the lower surface thereof, each of which is provided with a fifth threaded hole 18 , which is arranged corresponding to the third threaded hole 10 of the lower shell 101 . Bolts are passed through the fourth threaded hole 11 on the internal circuit board 14 and then connected to the fifth threaded hole 18 , so that the upper shell 102 and the lower shell 101 can be combined together to form the outer shell 1 .

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
