Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of PLC modules, and in particular relates to a PLC module which is convenient for installation and fastening of an expansion module. Background Art
[0002] Programmable logic controller, or PLC module, is a digital operation controller with a microprocessor for automatic control. It can load control instructions into memory at any time for storage and execution. The programmable controller is composed of CPU, instruction and data memory, input / output interface, power supply, digital analog conversion and other functional units. The early programmable logic controller only had the function of logic control, so it was named programmable logic controller. Later, with continuous development, these computer modules with simple functions have various functions including logic control, timing control, analog control, multi-machine communication, etc.
[0003] At present, when the existing PLC module is combined and connected with the expansion module, the sub-bar on the side of the expansion module is directly inserted into the mother bar on the side of the PLC module, thereby realizing the connection and fixation between the PLC module and the expansion module, which is similar to the connection between a plug and a socket in life. This connection method is not firm and is easily disconnected due to external forces.
[0004] Secondly, since the busbar of the PLC module is arranged inside the side of the PLC module, after the PLC module is assembled and installed on the fixed bracket between the PLC module and the expansion module, the expansion module is difficult to disassemble. Utility Model Content
[0005] (1) Technical issues to be solved
[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a PLC module that is easy to install and fasten the expansion module, aiming to solve the technical problems in the prior art that the connection between the PLC module and the expansion module is not firm and is easy to become disconnected, and that after the PLC module is combined with the expansion module and installed on a fixed bracket, the expansion module is difficult to disassemble.
[0007] (2) Technical solution
[0008] In order to solve the above technical problems, the utility model provides a PLC module that is convenient for installation and fastening of an expansion module, including a PLC module body and a PLC expansion module, two groups of first fixed rails are symmetrically arranged on one side of the PLC module body, first fixed grooves are opened inside the two groups of first fixed rails, and a PLC module busbar pin is also arranged on one side of the PLC module body and between the two groups of first fixed rails;
[0009] Two groups of second fixed rails are symmetrically arranged on one side of the PLC expansion module, and second fixed grooves are opened inside the two groups of second fixed rails. A PLC expansion module busbar pin is also arranged on one side of the PLC expansion module and between the two groups of second fixed rails. Two groups of sliding cards are symmetrically arranged on the other side of the PLC expansion module, and a PLC expansion module sub-plug is also arranged between the two groups of sliding cards.
[0010] When using this solution: by inserting the two sets of sliding cards on one side of the PLC expansion module into the two sets of first fixed grooves on the side of the PLC module body respectively, and then pressing the PLC expansion module to make the surface of the PLC expansion module flush with the surface of the PLC module body, at this time, the PLC expansion module sub-plug will be automatically inserted into the pin header shell and electrically connected with the PLC module mother pin header, thereby realizing the combined connection between the PLC expansion module and the PLC module body. At the same time, due to the engagement between the sliding card and the first fixed groove, a force can be generated between the PLC expansion module and the PLC module body in the X-axis direction, thereby making the connection between the PLC module body and the PLC expansion module tighter and less likely to become disconnected.
[0011] Preferably, the PLC module body and the PLC expansion module can be connected to each other.
[0012] Furthermore, the outside of the PLC module busbar pins and the PLC expansion module busbar pins are covered with a pin header shell, which is used to protect the PLC module busbar pins and the PLC expansion module busbar pins, effectively preventing external forces from causing damage to the PLC module busbar pins and the PLC expansion module busbar pins.
[0013] Furthermore, the cross-sections of the first fixed groove and the second fixed groove are both trapezoidal, and the sizes of the first fixed groove and the second fixed groove are both compatible with the sliding card. By sliding the sliding card into the first fixed groove and the second fixed groove, not only a firm connection between the PLC module main body and the PLC expansion module can be achieved, but also a firm connection between the PLC expansion modules and the PLC expansion modules can be achieved.
[0014] Furthermore, the PLC expansion module sub-socket can be inserted into the pin header shell and can be electrically connected to the PLC module busbar pins and the PLC expansion module busbar pins. Through the electrical connection between the PLC expansion module sub-socket and the PLC module busbar pins and the PLC expansion module busbar pins, connection and communication between the PLC module main body and the PLC expansion module and between the PLC expansion modules can be realized.
[0015] Furthermore, the PLC module busbar pins, the PLC expansion module busbar pins and the PLC expansion module sub-pins are all L-shaped, extending from the inside of the PLC module body and the PLC expansion module respectively. Through the L-shaped bending and extension of the busbars, the sub-pins do not need to be inserted into the PLC module body or the PLC expansion module to achieve the connection between the busbars, thereby removing the restrictions on the Z-axis between the PLC modules, thereby facilitating the disassembly and replacement of the PLC expansion modules.
[0016] (3) Beneficial effects
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model can generate interaction force in the X-axis direction when the PLC module body and the PLC expansion module and multiple PLC expansion modules are combined through the mutual engagement between the sliding card and the first fixing groove and the second fixing groove, thereby realizing a firm connection between the PLC module body and the PLC expansion module and multiple PLC expansion modules;
[0019] 2. The utility model can remove the restrictions on the Z axis between PLC modules by bending and extending the PLC module busbar pins, the PLC expansion module sub-plug and the PLC expansion module busbar pins into an L-shape, thereby facilitating the disassembly and replacement of the PLC expansion module.
