[0002] Self-locking input / output terminal blocks are electrical connection accessories with a mechanical self-locking structure. Their core uses a snap, spring or other self-locking mechanism to automatically and firmly clamp and lock the wire after it is inserted. Wiring can be fixed without additional tools, and the locking can be released through a specific operation to facilitate wire disconnection.

[0003] In electrical systems, it enables fast and reliable connection of input and output wires. Through its self-locking function, it ensures that the connection parts are not easily loosened under vibration, impact and other environments, reduces the risk of poor contact, and improves wiring efficiency and safety. It is widely used in circuit connection links in industrial control, power equipment, instrumentation and other scenarios.

[0004] In existing technologies, terminal block assemblies do not have a quick self-locking device, which means that the wiring process relies on external tools such as screwdrivers for tightening and fixing. This is not only cumbersome and inefficient, but also significantly increases labor costs, especially in batch wiring scenarios. Therefore, a self-locking input / output terminal block assembly is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-locking input / output terminal block assembly, which aims to improve the problems of cumbersome operation and low efficiency in the prior art, especially the significant increase in labor costs in batch wiring scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-locking input / output terminal block assembly includes a first connecting shell, a telescopic column fixedly connected to the top of the first connecting shell, a push plate fixedly connected to the top of the telescopic column, a limit post fixedly connected to the bottom of the push plate, a second connecting shell movably connected to the outside of the first connecting shell, a fixing block fixedly connected to the top of the first connecting shell, and through holes opened on the outside of both the first and second connecting shells, with a limiting component fixedly connected inside the through holes.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a limiting ring, the outside of which is fixedly connected to the inside of the through hole. A plurality of connecting posts are fixedly connected to the bottom of the limiting ring, and a positioning post is slidably connected to one end of each connecting post.

[0010] As a further description of the above technical solution:

[0011] A positioning ring is fixedly connected to the other end of the connecting column, and a spring is sleeved on the outside of the connecting column.

[0012] As a further description of the above technical solution:

[0013] One end of the second spring is fixedly connected to the outside of the limiting ring, and the other end of the second spring is fixedly connected to the top of the positioning ring.

[0014] As a further description of the above technical solution:

[0015] The top of the second connecting shell has a limiting hole, and the outside of the limiting post is slidably connected to the inside of the limiting hole.

[0016] As a further description of the above technical solution:

[0017] A spring is fitted around the outside of the telescopic column, and the button is rotatably connected to the inner wall of the fixed block.

[0018] As a further description of the above technical solution:

[0019] The top of the first spring is fixedly connected to the bottom of the button plate, and the bottom of the first spring is fixedly connected to the top of the first connecting shell.

[0020] As a further description of the above technical solution:

[0021] The positioning ring is internally connected to a circuit, and the outside of the positioning ring is connected to the outside of the limiting ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the first connecting shell is picked up and aligned with the interface of the second connecting shell. The protruding end of the first connecting shell is inserted into the second connecting shell to form a preliminary limit. Pressing the button plate compresses the telescopic column and the first spring, causing the bottom limit column to move downward and accurately embed into the limit hole of the second connecting shell. The two shells are firmly connected by mechanical locking. The connection and locking can be completed quickly without tools, avoiding loosening caused by insufficient manual tightening and improving connection stability.

[0024] 2. In this utility model, when fixing the line, the line is inserted into the housing through the through hole. After the positioning ring contacts the line, it slides and adjusts according to the diameter of the line through the connecting column. The spring generates elastic force due to deformation, which, together with the upward pressure of the positioning column, pushes the positioning ring to tightly wrap the line, thereby achieving self-adaptive fixing.

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.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a self-locking input / output terminal block assembly, comprising a connecting shell 1 for supporting the internal structure and realizing the main connection function, a telescopic column 2 that can be elastically extended and retracted fixedly connected to the top of the connecting shell 1, the telescopic column 2 can provide buffer and reset support for the top structure, a push plate 4 that is easy to operate manually fixedly connected to the top of the telescopic column 2, the push plate 4 can drive the related components to move by pressing, and a limiting post 5 for limiting and fixing fixedly connected to the bottom of the push plate 4, the limiting post 5 can realize locking between the connecting shells when pressed;

[0033] The top of the connecting shell 2 7 is provided with a limiting hole 8 that cooperates with the limiting post 5. The outside of the limiting post 5 is slidably connected to the inside of the limiting hole 8. When the limiting post 5 enters the limiting hole 8, it can restrict the protruding end of the connecting shell 1, so as to achieve stable docking between the connecting shell 1 and the connecting shell 2 7.

[0034] The telescopic column 2 is fitted with a spring 3 that provides a restoring force. The spring 3 can drive the button plate 4 to rebound after being pressed. The button plate 4 is externally rotatably connected to the inner wall of the fixing block 6. The fixing block 6 provides a fulcrum for the rotation of the button plate 4, ensuring stable and smooth pressing operation.

[0035] Reference Figure 2 and Figure 4 The limiting component includes a limiting ring 10 that serves as a basic fixing element. The limiting ring 10 is externally fixedly connected to the inside of the through hole 9, providing a mounting carrier for the limiting component. The bottom of the limiting ring 10 is fixedly connected to a plurality of connecting posts 11 for support and guidance. The connecting posts 11 provide a path for the movement of subsequent components. One end of the connecting post 11 is slidably connected to a positioning post 14 that can be elastically lifted. The positioning post 14 can apply upward pressure to the positioning ring 13.

[0036] The other end of the connecting post 11 is fixedly connected to a positioning ring 13 for wrapping the line. The positioning ring 13 can directly contact the line 15 to achieve fixation. A spring 12 that can provide elastic force is sleeved on the outside of the connecting post 11. The spring 12 provides power for the adjustment and fixation of the positioning ring 13.

[0037] One end of the second spring 12 is fixedly connected to the outside of the limiting ring 10, and the other end is fixedly connected to the top of the positioning ring 13. By fixing both ends, the second spring 12 can stably generate elastic tension, ensuring continuous pressure on the positioning ring 13.

[0038] Reference Figure 1 and Figure 2 The top of spring 3 is fixedly connected to the bottom of the button plate 4, and the bottom is fixedly connected to the top of the connecting shell 1. By fixing the top and bottom, spring 3 is compressed and stores force when the button plate 4 is pressed, and automatically pushes the button plate 4 to reset after being released.

[0039] The positioning ring 13 has a movable connection to the wire 15 that needs to be fixed. The wire 15 can pass through the positioning ring 13 and enter the terminal block. The outside of the positioning ring 13 and the outside of the limiting ring 10 form an elastic adjustment structure through the connecting post 11 and the spring 12. It can adaptively adjust according to the different sizes of the wire 15. With the lifting pressure of the positioning post 14, the wire 15 is firmly fixed.

[0040] Working principle: When the shells are connected, pick up connecting shell 1 and align it with the interface of connecting shell 2 7. The protruding end of connecting shell 1 is inserted into connecting shell 2 7 to form a preliminary limit. Press the button 4 to compress the telescopic column 2 and spring 3, which drives the bottom limit column 5 to move downward and accurately embed into the limit hole 8 of connecting shell 2 7. The two shells are firmly connected by mechanical locking. After releasing the button 4, the spring 3 rebounds to reset the structure and complete the shell self-locking.

[0041] When fixing the line, the line 15 is inserted into the housing through the through hole 9. After the positioning ring 13 contacts the line 15, it slides and adjusts according to the diameter of the line through the connecting post 11. The spring 12 generates elastic force due to deformation, which, together with the upward pressure of the positioning post 14, pushes the positioning ring 13 to tightly wrap the line 15, thus achieving self-adaptive fixing.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
