Description

Technical Field

[0001] This utility model relates to the field of overload protector technology, specifically a snap-fit ​​base overload protector. Background Technology

[0002] Overload protectors are commonly referred to as: torque retainers, overload protectors, torque clutches, torque limiters, axial load overload protectors, torque limiters, safety clutches, safety couplings, force-limiting clutches, clutch force limiters, ball clutches, friction clutches. The function of overload protectors is to be installed between the driving and driven sides of a power transmission system. When an overload fault occurs, the torque limiter disengages, effectively protecting the drive machinery and the load. Common types are friction-type torque limiters and ball-type torque limiters. The mounting structures of torque limiters include: shaft-to-shaft, shaft-to-flange, shaft-to-synchronous pulley, shaft-to-sprocket, shaft-to-gear, and shaft-to-pulley.

[0003] Existing overload protectors can monitor the current changes of the electrical system in real time. When the current exceeds the set value, it will automatically cut off the power supply to prevent the equipment from being damaged due to overload. However, when installing overload protectors, it is not possible to properly separate and fix the wires before wiring. This makes it difficult to reduce wiring errors caused by messy wires when connecting multiple overload protectors. After wiring the overload protectors, it is also difficult to fix the wires again to ensure a more secure connection and reduce the problem of detachment due to vibration or external force. Therefore, a utility model is proposed to solve the above problems. Utility Model Content

A fixed slide rail 17 is inserted into one side of the power input / output seat 13. An installation component 18 is slidably connected inside the fixed slide rail 17.

[0019] As a preferred embodiment of this example, Figures 2 to 5As shown, a protective plate 2 is inserted inside the protective base shell 1. A protective button 3 is inserted into one end of the protective plate 2. A protective outer shell 4 is installed on one side of the protective base shell 1 via a connector. A button spring 5 is inserted into one end of the protective button 3. From front to back, a power inlet terminal 6 and a power outlet terminal 7 are arranged sequentially on one side of the protective plate 2. A metal piece 8 is provided on one side of the power outlet terminal 7. A contact point 801 is provided on one side of the metal piece 8. A power inlet terminal 6 is provided at one end of the metal piece 8. A power inlet socket 9 is sleeved on the surface of the power inlet terminal 6. A power outlet socket 10 is sleeved on the surface of the power outlet terminal 7. The upper surface is provided with an output buckle 11, and the upper surface of the input socket 9 is provided with an input buckle 12.

An input / output housing 14 is installed on one side of the input / output socket 13 through a connector. During use, the overload bolt is rotated to move it upward on the inlet / outlet socket 13. The two wires to be connected to the equipment are then inserted into the outlet clip 11 and inlet clip 12 installed in the inlet / outlet socket 13, respectively. The overload bolt is then rotated to secure the wires inserted into the outlet clip 11 and inlet clip 12. The inlet terminal 6 and outlet terminal 7 installed in the protective base 1 are then inserted into the inlet socket 9 and outlet socket 10 inside the inlet / outlet socket 13 to connect the power supply. After power is connected, the equipment operates under overload conditions. The overheating of the metal sheet 8 causes the contact point 801 to separate from the power input terminal 6. After worker inspection and cooling of the metal sheet 8, the protection button 3 is pushed and slids within the protective housing 1 via the button spring 5. The protection button 3 moves downward to contact the metal sheet 8, reconnecting the contact point 801 of the metal sheet 8 to the power input terminal 6, thereby supplying power to the equipment and restarting its operation. This effectively prevents the equipment from overheating, aging of insulation, or even burning out due to prolonged overload, ensuring the long-term stable operation of the equipment.

[0020] like Figures 6 to 8As shown, in this embodiment, fixed threaded seats 15 are inserted into both sides of the inlet / outlet socket 13. A fixing assembly 16 is installed on one side of the fixed threaded seat 15 via a base bolt. The fixing assembly 16 includes a fixing rod 161, a fixing seat 162, a fixing shaft seat 163, a clamping seat 164, a fixing bolt 165, a fixing plate 166, and a clamping bolt 167.

The clamping seat 164 is rotatably connected inside the fixing shaft seat 163. The fixing bolt 165 is threaded through the upper surface of the clamping seat 164. The fixing plate 166 is sleeved on one end of the fixing bolt 165. The clamping bolt 167 is threaded through one end of the clamping seat 164. A fixing groove is inserted into the upper surface of the fixing plate 166, and a fixing bearing is inserted into the fixing groove. A fixing bolt 165 is inserted into the fixing bearing. A fixing slide rail 17 is inserted into one side of the inlet / outlet socket 13. A mounting assembly 18 is slidably connected inside the fixing slide rail 17. The mounting assembly 18 includes a mounting base 181, a mounting spring 182, a mounting rod 183, and a mounting handle 184. The mounting spring 182 is provided on the lower surface of the mounting base 181. The mounting rod 183 is inserted into the inside of the mounting spring 182. The mounting handle 184 is inserted into the upper surface of the mounting rod 183. A mounting slider is provided on one side of the mounting assembly 18. A mounting slider is slidably connected inside the fixing slide rail 17. A slide rail threaded hole is provided inside the fixing slide rail 17. The mounting slider has internal threaded holes. The mounting slide rail 17 is connected to the mounting slider via mounting bolts. During use, the mounting slider on one side of the mounting assembly 18 is inserted into the fixed slide rail 17. By rotating the mounting bolts, the mounting assembly 18 is installed within the fixed slide rail 17. Pulling the mounting handle 184 moves the mounting rod 183 upward, compressing the mounting spring 182. The worker places the sorted wires onto the mounting base 181. The worker then lowers the mounting handle 184, and the spring force of the mounting spring 182 causes the mounting rod 183 to press down and tighten the wires on the mounting base 181. The mounting assembly 18 on the inlet / outlet side of the electrical base 13 further presses down and fixes the wires. During equipment installation, the worker can quickly... Wiring is performed in advance, making it easier for workers to sort and fix the wires before wiring. The purpose and connection position of each wire are clearly visible, reducing electrical faults and safety hazards caused by wiring errors. Pre-sorting and fixing the cables reduces on-site chaos, making wiring work more organized and improving work efficiency. The clear wiring also facilitates subsequent maintenance and repair. The fixing assembly 16 is secured to both sides of the inlet / outlet socket 13 by rotating the base bolts. The clamping bolt 167 is rotated to open the clamping seat 164 on the fixed shaft seat 163. The wires to be installed in the inlet / outlet socket 13 are placed into the fixing seat 162. The clamping seat 164 and the fixing seat 162 are closed by rotating the clamping seat 164.By rotating the clamping bolt 167 to fix the clamping seat 164 and the fixing seat 162, and by rotating the fixing bolt 165 to move the fixing plate 166 downward within the clamping seat 164, the fixing plate 166 secures the wires within the clamping seat 164 and the fixing seat 162. This fixation by the fixing plate 166 ensures a more secure connection after wiring, reducing the risk of detachment due to vibration or external forces, and improving the stability and reliability of the connection.

[0021] The working principle of this practical application is as follows: During use, the worker rotates the overload bolt to move it upward on the inlet / outlet socket 13. The worker then rotates the mounting bolt to install the mounting assembly 18 within the fixed slide rail 17. Pulling the mounting handle 184 moves the mounting rod 183 upward, compressing the mounting spring 182. The worker places the divided wires onto the mounting base 181. Lowering the mounting handle 184, the worker uses the spring force of the mounting spring 182 to press the mounting rod 183 down onto the mounting base 181, tightening the wires. After the workers have sorted and secured the other wires, they rotate and remove the clamping bolt 167 to open the clamping seat 164 on the fixed shaft seat 163. The wires installed on the mounting base 181 and placed in the inlet / outlet socket 13 are then placed into the fixed seat 162. The two wires to be connected to the equipment are inserted into the outlet clip 11 and inlet clip 12 installed in the inlet / outlet socket 13, respectively. The overload bolt is then rotated to secure the wires inserted into the outlet clip 11 and inlet clip 12. The worker rotates the clamping seat 164 to close the clamping seat 164 and the fixed seat 162, and then rotates the clamping bolt 167 to fix the clamping seat 164 and the fixed seat 162. By rotating the fixing bolt 165, the fixing plate 166 moves downward within the clamping seat 164, thereby fixing the wires inside the clamping seat 164 and the fixed seat 162. The worker then inserts the power input terminal 6 and the power output terminal 7 installed inside the protective bottom shell 1 into the power input terminal 9 and the power output terminal 7 in the power input / output terminal 13. The power is switched on inside the socket 10. After the power is switched on, the equipment will operate under overload, causing the metal plate 8 to overheat and the contact point 801 to separate from the power input terminal 6. After the worker checks and the temperature of the metal plate 8 drops, the protection button 3 is pushed and the button spring 5 causes the protection button 3 to slide within the protective bottom shell 1. The protection button 3 moves downward to contact the metal plate 8, so that the contact point 801 of the metal plate 8 is reconnected to the power input terminal 6, and the equipment is powered on again to start working.

[0022] 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.
