[0002] With the continuous development of automation technology, PLC (Programmable Logic Controller), as one of the core devices of industrial control systems, has been widely used in various automated equipment and production lines. PLC controllers achieve efficient management of machines and production processes through the acquisition, processing and output control of input signals.

[0003] However, existing PLC controllers are used by directly plugging the connector into the interface. This connection method can cause problems such as instability, loose connection, and poor contact between the connector and the interface. Especially under vibration and external pulling force, it can easily affect the signal transmission and working stability of the equipment, and thus affect the performance and reliability of the entire automation control system. To solve these problems, a quick-plug PLC controller is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-connect PLC controller, which aims to improve the connection method of existing PLC controllers in the prior art. This method can cause problems such as unstable connection, loose connection, and poor contact in the connection of plugs and interfaces, which can easily affect the signal transmission and working stability of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect PLC controller, comprising a PLC controller housing, a heat dissipation window on the side wall of the PLC controller housing, a connector on one side of the PLC controller housing, a wire fixedly connected to the other end of the connector, a uniformly distributed interface on the surface of the connector, a fixing component at the connection between the interface and the connector, the fixing component including mounting grooves symmetrically formed inside the PLC controller housing, a limit block inside the PLC controller housing, a compression spring fixedly connected to the top surface of each limit block, a connecting rod fixedly connected to the bottom surface of each limit block, an arc-shaped limiting member connected to the bottom surface of each connecting rod, a connecting plate fixedly connected to the end of the arc-shaped limiting member away from the PLC controller housing, an L-shaped pull block fixedly connected to the end of the connecting plate away from the arc-shaped limiting member, and an annular limiting groove on the surface of the connector;

[0006] As a further description of the above technical solution: multiple insertion interfaces are provided, and the fixing components are all provided on the upper and lower sides of the insertion interface;

[0007] As a further description of the above technical solution: the fixing components are grouped in pairs, and the number of fixing components is the same as the number of plug-in interfaces;

[0008] As a further description of the above technical solution: the limiting block is slidably connected inside the mounting groove, and the connecting rod is slidably connected inside the mounting groove;

[0009] As a further description of the above technical solution: the compression spring is disposed inside the mounting groove, and the other end of the compression spring is fixedly connected to the inner wall surface of the mounting groove;

[0010] As a further description of the above technical solution: the arc-shaped limiting member and the annular limiting groove are adapted to each other, and the surface of the arc-shaped limiting member near the plug is in contact with the inside of the annular limiting groove.

[0011] As a further description of the above technical solution: the L-shaped pull blocks are all arranged opposite each other, and the limiting block and the mounting groove abut against each other;

[0012] As a further description of the above technical solution: the diameter of the connecting rod is smaller than the diameter of the limiting block, and the plug is connected to the plug interface by plugging.

[0013] This utility model has the following beneficial effects:

[0014] 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a quick-connect PLC controller, including a PLC controller housing 1. A heat dissipation window 2 is provided on the side wall of the PLC controller housing 1. A connector 3 is provided on one side of the PLC controller housing 1, and a wire 4 is fixedly connected to the other end of the connector 3. Insertion interfaces 5 are evenly distributed on the surface of the connector 3. Fixing components 6 are provided at the connection points of the insertion interfaces 5 and the connector 3. The fixing components 6 include mounting grooves 61 symmetrically formed inside the PLC controller housing 1. Limiting blocks 62 are provided inside the PLC controller housing 1. Compression springs 63 are fixedly connected to the top surface of each limiting block 62, and connecting rods 6 are fixedly connected to the bottom surface of each limiting block 62. 4. The bottom surface of the connecting rod 64 is connected to an arc-shaped limiting member 65. The end surface of the arc-shaped limiting member 65 away from the PLC controller housing 1 is fixedly connected to a connecting plate 66. The end surface of the connecting plate 66 away from the arc-shaped limiting member 65 is fixedly connected to an L-shaped pull block 67. The surface of the plug 3 is provided with an annular limiting groove 68. When the plug 3 is inserted into the plug interface 5, the arc-shaped limiting member 65 will cooperate with the annular limiting groove 68 on the surface of the plug interface 5 to ensure that the plug 3 is firmly fixed after insertion. The limiting block 62 and the connecting rod 64 are slidably connected in the mounting groove 61 and a certain compression force is provided by the compression spring 63 to enhance the stability of the connection and prevent the plug 3 from loosening due to vibration or external force.

[0024] Reference Figure 1 - Figure 4Multiple insertion interfaces 5 are provided, and fixing components 6 are provided on the upper and lower sides of each insertion interface 5. The fixing components 6 are arranged in pairs, and the number of fixing components 6 is the same as that of insertion interfaces 5. The limiting block 62 is slidably connected to the inside of the mounting groove 61, the connecting rod 64 is slidably connected to the inside of the mounting groove 61, the compression spring 63 is provided inside the mounting groove 61, and the other end of the compression spring 63 is fixedly connected to the inner wall surface of the mounting groove 61. The arc-shaped limiting member 65 is adapted to the annular limiting groove 68, and the surface of the arc-shaped limiting member 65 near the insertion connector 3 abuts against the annular limiting groove 68. Inside the slot 68, L-shaped pull blocks 67 are arranged opposite each other, the limiting block 62 abuts against the mounting slot 61, the diameter of the connecting rod 64 is smaller than the diameter of the limiting block 62, the plug 3 is connected to the plug interface 5 by plugging, and the fixing components 6 are set on both sides of each plug interface 5 so that each plug interface 5 can be operated independently. The independent operation of each plug interface 5 allows the user to plug and unplug each interface individually without affecting the working status of other interfaces. The user can flexibly add, remove or replace the plug 3 as needed without interfering with the normal operation of the overall system.

[0025] Working principle: In use, the plug 3 is connected to the interface 5 via a plug-in method. Each interface 5 has multiple plugs 3, allowing multiple devices or signal channels to be connected through the same PLC controller. When the user needs to use the PLC, they only need to insert the plug 3 into the corresponding interface 5 for power or signal transmission. When the plug 3 is inserted, the L-shaped pull block 67 is adapted to the user's finger, thus moving the L-shaped pull block 67 away from the interface 5. The connecting plate 66 drives the arc-shaped limiting member 65 to move synchronously, thereby compressing the compression spring 63 through the connecting rod 64 and the limiting block 62. After the plug 3 is inserted, the plug 3 is released. When the finger leaves the surface of the plug 3, the compression spring 63 compresses the arc-shaped limiting member 65 through the connecting rod 64 and the limiting block 62, abutting against the inside of the annular limiting groove 68. The arc-shaped limiting member 65 and the annular limiting groove 68 fit tightly, ensuring that the plug 3 and the corresponding interface 5 are firmly connected, preventing the plug 3 from loosening due to external vibration, pulling, or improper operation.
