Description

Technical Field

[0001] This utility model relates to the field of wiring equipment technology, and in particular to a wiring device for a limit switch. Background Technology

[0002] Limit switches, as an important type of mechanical position sensor, play a key role in the field of industrial automation. They are mainly used to detect the position or motion state of a moving part in a mechanical device. When the mechanical part reaches the set position, the limit switch will output a signal to control the working state of the mechanical system.

[0003] Traditional limit switch wiring methods often suffer from unstable connections. During equipment operation, due to factors such as vibration and impact, the plug is prone to loosening or falling off, resulting in signal transmission interruption or instability. To solve the above problems, this utility model provides a limit switch connector. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a limit switch connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connector for a limit switch includes a limit switch body and a processor. A U-shaped frame is fixedly connected to the back of both the limit switch body and the processor. Threaded holes are provided on both sides of the U-shaped frame, and adjusting bolts adapted to the threaded holes are threaded to both sides of the U-shaped frame. A first slot is provided on the back of the limit switch body, and a first plug is inserted into the first slot. A second slot is provided on the surface of the processor, and a second plug is inserted into the second slot. Limit tubes are fixedly connected to the surfaces of both the first plug and the second plug. Limiting rings adapted to the limiting tubes are fixedly connected to the opposite ends of the two adjusting bolts.

[0007] As a further improvement of this utility model, a limiting groove is provided on the lower surface of the U-shaped frame, and a limiting rod that matches the limiting groove is fixedly connected to the lower surface of the limiting ring.

[0008] As a further improvement of this utility model, an adjusting nut is fixedly connected to the other end of the adjusting bolt.

[0009] As a further improvement of this utility model, a tap wire is fixedly connected to the back of the first plug, the other end of the tap wire is fixedly connected to a main wire, and the other end of the main wire is fixedly connected to the second plug.

[0010] As a further improvement of this utility model, a trigger rod is provided at one end of the upper surface of the limit switch body.

[0011] As a further improvement of this utility model, an anti-slip pad is fixedly connected inside the limiting ring, and the anti-slip pad is made of rubber.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating limiting rings, threaded holes are provided on both sides of the U-shaped frame during use, and adjusting bolts are threadedly connected to them. This allows the limiting rings to move towards each other and clamp the limiting tube, thus securely fixing the first and second plugs. This effectively prevents the plugs from loosening or falling off under vibration or external force. The limiting rings are internally fixed with anti-slip pads, increasing the friction between the limiting rings and the limiting tubes and preventing the plugs from sliding or loosening after fixing. This improves the reliability and stability of the wiring. At the same time, an adjusting nut is fixedly connected to the other end of the adjusting bolt, allowing operators to easily adjust the position of the limiting rings by rotating the adjusting nut, thereby tightening or loosening the plugs. This simplifies the installation and disassembly process and improves work efficiency.

[0014] By setting a limiting rod, a limiting groove is opened on the lower surface of the U-shaped frame during use, and a limiting rod that matches the limiting groove is fixedly connected to the lower surface of the limiting ring, so that the limiting ring will not rotate during movement, ensuring that the clamping force of the limiting ring on the limiting tube is always kept in the same direction, thus improving the fixing stability of the plug.

[0015] By setting up tap lines, multiple limit switch bodies can be flexibly connected to the processor through the connection method of tap lines and main lines during use. This not only facilitates the installation and wiring of the equipment, but also improves the scalability and flexibility of the equipment.

[0016] In summary, this utility model has a compact overall structure, occupies little space, and is easy to install and wire in a limited space. At the same time, the modular design makes maintenance and replacement more convenient and quick. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A connector for a limit switch includes a limit switch body 1 and a processor 17. A U-shaped frame 2 is fixedly connected to the back of both the limit switch body 1 and the processor 17. Threaded holes are provided on both sides of the U-shaped frame 2. Adjusting bolts 3 that are adapted to the threaded holes are threadedly connected to both sides of the U-shaped frame 2. A first slot 4 is provided on the back of the limit switch body 1. A first plug 5 is inserted into the inside of the first slot 4. A second slot 6 is provided on the surface of the processor 17. A second plug 7 is inserted into the inside of the second slot 6. Limit tubes 8 are fixedly connected to the surfaces of the first plug 5 and the second plug 7. Limiting rings 9 that are adapted to the limit tubes 8 are fixedly connected to the opposite ends of the two adjusting bolts 3.

[0023] In this utility model, a limiting groove 10 is provided on the lower surface of the U-shaped frame 2, and a limiting rod 11 that matches the limiting groove 10 is fixedly connected to the lower surface of the limiting ring 9. The cooperation between the limiting rod 11 and the limiting groove 10 ensures that the limiting ring 9 will not rotate when moving, thus ensuring that the clamping force of the limiting ring 9 on the limiting tube 8 is always kept in the same direction, which enhances the fixing effect of the plug. An adjusting nut 12 is fixedly connected to the other end of the adjusting bolt 3. The setting of the adjusting nut 12 makes it convenient for the operator to adjust the position of the limiting ring 9 by rotating the adjusting nut 12.

[0024] A tap 13 is fixedly connected to the back of the first plug 5. The tap 13 is used to transmit the signal of the limit switch body 1 to the main wire 14, realizing flexible signal distribution and transmission. The other end of the tap 13 is fixedly connected to the main wire 14. The main wire 14 serves as the main channel for signal transmission, summing up the signals from multiple taps 13 and transmitting them to the second plug 7, ensuring signal integrity and stability. The other end of the main wire 14 is fixedly connected to the second plug 7. A trigger rod 15 is provided at one end of the upper surface of the limit switch body 1. The trigger rod 15 is used to trigger the limit switch when the mechanical part reaches the set position, generating a signal output. It is a key component for the limit switch body 1 to realize stroke control and limit protection. An anti-slip pad 16 is fixedly connected inside the limit ring 9. The anti-slip pad 16 is made of rubber. The anti-slip pad 16 increases the friction between the limit ring 9 and the limit tube 8, preventing the plug from sliding or loosening after fixing, and improving the reliability of the wiring.

[0025] In use, the first plug 5 of the tap line 13 is first inserted into the corresponding interface of the limit switch body 1. After the first plug 5 is fully inserted, the limit tube 8 will align with the two limit rings 9 inside the U-shaped frame 2. At this time, the adjusting nuts 12 on both sides of the U-shaped frame 2 are rotated to drive the adjusting bolts 3 to rotate synchronously, thereby driving the two limit rings 9 to move towards each other. During this process, the limiting rod 11 below the limit ring 9 will slide in the limiting groove 10 of the U-shaped frame 2, preventing the limit rings 9 from rotating during the movement. When the two limit rings 9 firmly clamp the limit tube 8, the first plug 5 is firmly fixed to the limit switch body 1. Then, the above steps are repeated for the other tap lines. The first plug 5 of 13 is inserted into the other limit switch bodies 1 in sequence to complete the wiring of multiple limit switch bodies 1. After all limit switch bodies 1 are installed, the second plug 7 of the main wire 14 at the other end of several tap wires 13 needs to be inserted into the second slot 6 of the processor 17. Similarly, the second plug 7 is firmly fixed to the processor 17 by the clamping action of the limit ring 9. Finally, when the trigger rod 15 on the limit switch body 1 is triggered, it will immediately transmit the signal quickly to the processor 17 through the tap wires 13 and the main wires 14. After receiving the signal, the processor 17 will quickly process the signal and control the working state of the mechanical system according to the processing result.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
