[0001] This utility model relates to the field of transmission mechanism technology, and in particular to a clutch. Background Technology
[0002] An electronically controlled silicone oil clutch is a clutch device that uses electronic control technology. It operates and controls the clutch through a computer control system. Unlike traditional mechanical clutches, electronically controlled silicone oil clutches offer more precise control over the clutch's working state, providing a better driving experience and higher reliability. Its working principle utilizes electromagnetic force to control the flow of silicone oil, thereby altering the clutch's friction torque. When the electronic control system receives a driver command, it regulates the flow of silicone oil by controlling a solenoid valve, thus achieving clutch engagement and disengagement.
[0003] For example, the authorization announcement number "CN221323110U" is named a split-type electronically controlled silicone oil clutch. Through the connection line protection component, it can both use the closure of the first and second protective covers to shield and protect the connection line of the power plug, thereby preventing the fan blades from hitting the connection line and effectively improving the service life of the connection line. At the same time, it can use the cooperation of two wire clamping plates to clamp the connection line of the power plug, thereby preventing the connection between the connection line and the power plug from shaking, and further improving the service life of the power plug.
[0004] The above-mentioned and existing technologies have the following defects: the grooves and engagement slots of the teeth of the clutch are exposed to the outside, and they are easy to get dust and oil stains during use. It is also difficult to open the first and second protective covers afterward, making it inconvenient to inspect and repair the connector and power plug. Utility Model Content

[0020] 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.
[0021] Reference Figure 1-5 A clutch includes a clutch body 1. A connector 2 is located at the rear end of the clutch body 1. A power plug 3 is inserted into the connector 2. A connecting wire 4 is located on the lower surface of the power plug 3. A first protective sleeve 5 is fitted over the connector 2. A snap-fit hole 6 is opened at the rear end of the first protective sleeve 5. A disassembly trigger device is slidably connected to the outside of the first protective sleeve 5. A second protective sleeve 7 is fitted over the upper part of the connecting wire 4 and slidably connected to the first protective sleeve 5. A wire clamp 8 is located at the lower end of the second protective sleeve 7 and is fitted over the connecting wire 4. The outer diameter of the wire clamp 8 is larger than the outer diameter of the first protective sleeve 5, thus enabling the wire clamp 8 to provide a seal. A mounting groove 9 is opened at the rear end of the second protective sleeve 7. A snap-fit block 10 matching the snap-fit hole 6 is slidably connected to the inner wall of the mounting groove 9. The rear surface of the snap-fit block 10 is inclined forward from bottom to top, which facilitates the snap-fit block 10 sliding into the first protective sleeve 5. Two first return springs 11 are provided between the snap-fit block 10 and the front inner wall of the mounting groove 9.
[0022] The disassembly triggering device includes a slider 12 that is slidably connected to the first protective sleeve 5. The rear end of the slider 12 has an installation through hole 13. The installation through hole 13 has a squeeze button 14 inside. The inner walls of the upper and lower sides of the installation through hole 13 are provided with first limiting grooves 15. The inner walls of the two first limiting grooves 15 are slidably connected with first limiting blocks 16 that are fixedly connected to the squeeze button 14. The front surface of the adjacent first limiting blocks 16 and the front inner wall of the first limiting groove 15 are provided with second return springs 17.
[0023] The first protective sleeve 5 has a positioning groove 18 on its front inner wall, and the second protective sleeve 7 has a positioning block 19 at its front end that matches the positioning groove 18. The positioning block 19 extends into the positioning groove 18.
[0024] The lower end of the first protective sleeve 5 is provided with a first stop 20, which is located below the snap-fit hole 6. The upper end of the first protective sleeve 5 is provided with a second stop 21. The first stop 20 and the second stop 21 serve to limit the movement of the slider 12.
[0025] The upper and lower inner walls of the mounting groove 9 are provided with second limiting grooves 22, and the inner walls of the two second limiting grooves 22 are slidably connected with second limiting blocks 23 that are fixedly connected to the snap-fit block 10. The second limiting blocks 23 slide within the second limiting grooves 22, making the snap-fit block 10 move more stably.
[0026] The front surface of the mounting slot 9 has two concealed slots 24 that correspond one-to-one with the first return spring 11. One end of the first return spring 11 is disposed on the front inner wall of the concealed slot 24. The concealed slots 24 can position the first return spring 11 and prevent the locking block 10 from shifting when compressing the first return spring 11.
[0027] Working principle: When it is necessary to protect the connector 2 and the power plug 3, first plug the connector 2 and the power plug 3 into each other. Then, hold the cable clamp 8 and push the second protective sleeve 7 into the first protective sleeve 5 along the positioning groove 18 through the positioning block 19. At this time, the snap-fit block 10 is compressed into the mounting groove 9 by the inner wall of the first protective sleeve 5. When the snap-fit block 10 reaches the snap-fit hole 6, the snap-fit block 10 is ejected from the snap-fit hole 6 by the compression action of the first return spring 11, so that the first protective sleeve 5 and the second protective sleeve 7 are fixedly connected. The first protective sleeve 5 and the second protective sleeve 7 play the role of protecting the connector 2 and the power plug 3 and preventing the connector 2 and the power plug 3 from shaking.
[0028] When it is necessary to disconnect the power plug 3 from the connector 2, the disassembly trigger device is installed. By moving the slider 12 to the first stop 20 position, and then pressing the squeeze button 14, the snap-fit block 10 is squeezed by the squeeze button 14, causing the snap-fit block 10 to disengage from the snap-fit through hole 6. Then, by pulling the cable holder 8, the power plug 3 can be disconnected from the connector 2. In summary, the first protective sleeve 5 and the second protective sleeve 7 do not need to worry about dust and oil stains during use. Through the above operation, the first protective sleeve 5 and the second protective sleeve 7 can be quickly separated, facilitating the maintenance of the power plug 3 and the connector 2.
[0029] 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.
