[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution: Figure 1-Figure 5 An insulating sleeve for protecting electrical equipment shown in the figure includes an insulating sleeve main body 1, one end of the insulating sleeve main body 1 is rotatably connected to a connecting sleeve 2, the inside of the connecting sleeve 2 is rotatably connected to the side away from the insulating sleeve main body 1, and the mounting sleeve 3 is fixedly connected to the mounting tube 4 at the end away from the connecting sleeve 2. A breaking groove 5 is opened on the outside of the connecting sleeve 2, and a cutting plate 6 is abutted on the outside of the breaking groove 5. A pushing assembly is provided on the side of the cutting plate 6 away from the breaking groove 5, and the pushing assembly includes a lower pressing plate 7, which is arranged in an inclined shape, and the lower pressing plate 7 is fixedly connected to one side of the cutting plate 6 near the mounting tube 4, and the end of the lower pressing plate 7 away from the cutting plate 6 is rotatably connected to a worm rod 8, and the worm rod 8 is fixedly connected to the outside of the mounting tube 4.

[0020] During operation, first put the mounting tube 4 and the mounting sleeve 3 on one end of the wiring harness, and then put the insulating sleeve main body 1 on the other end that needs to be connected. At this time, rotate the connecting sleeve 2 to connect the insulating sleeve main body 1 with the mounting sleeve 3. When a short circuit occurs in the line, high temperature will be generated at the connection. At this time, the connection of the connecting sleeve 2 is thinner, and the weak part becomes soft, and the worm spring rod 8 will apply rotational force to the lower pressure plate 7. At this time, the lower pressure plate 7 can drive the cutting plate 6 to press down, allowing the cutting plate 6 to cut the connecting sleeve 2 along the fracture groove 5. In this way, the short-circuited line can be quickly cut off, thereby performing rapid processing, achieving the effect of quickly disconnecting the line connection, solving the problem that high temperature will be generated at the connection when a short circuit occurs in the circuit, causing problems in line transmission and causing irreversible damage to the equipment, and improving the line protection effect.

[0021] See also Figure 1 、 Figure 2 and Figure 4 In the figure, the lower pressure plate 7 is abutted against the side of the mounting tube 4 with a support rod 10. There are two groups of support rods 10 symmetrically arranged. The mounting tube 4 is provided with a sliding groove 11 on the side close to the lower pressure plate 7. The support rod 10 is slidably connected inside the sliding groove 11. A support assembly is provided at the end of the support rod 10 away from the lower pressure plate 7. The outside of the insulating sleeve main body 1 is fixedly connected to the limiting plate 9. The mounting tube 4 is rectangular, and the mounting tube 4 is connected to the mounting sleeve 3, and the mounting sleeve 3 is connected to the insulating sleeve main body 1.

[0022] During operation, the mounting tube 4 and the mounting sleeve 3 are directly put on one end of the wiring harness, and the mounting tube 4 is fixed to one end of the line by hot melt adhesive, and then the insulating sleeve body 1 is put on the outside of the other wiring harness, and the end of the insulating sleeve body 1 away from the mounting sleeve 3 is pinched and deformed to connect the lines. In this way, the two lines can be docked. After the overall installation, the support rod 10 can be slid along the sliding groove 11, so that the support rod 10 supports the lower pressure plate 7. The limit plate 9 can prevent the connecting sleeve 2 from slipping off from the outside of the insulating sleeve body 1, ensuring that the connecting sleeve 2 will not be broken at the breaking groove 5 due to excessive pressure generated by the lower pressure plate 7, thereby achieving the effect of auxiliary support of the lower pressure plate 7.

[0023] See also Figure 4 and Figure 5 In the figure, the support assembly includes a support plate 13, a telescopic groove 14 is opened near the support plate 13 of the support rod 10, the support plate 13 is slidably connected inside the telescopic groove 14, a fixed groove 16 is opened on the outside of the mounting tube 4, a thermal sheet 15 is fixedly connected inside the fixed groove 16, one side of the thermal sheet 15 is fixedly connected to the end of the support plate 13 away from the support rod 10, and one side of the support rod 10 is fixedly connected to the limiting block 12 near the lower pressure plate 7.

[0024] During operation, when a short circuit occurs in the circuit, high temperature is generated at the connection. At this time, the thermal sheet 15 will be deformed by the high temperature, so that the thermal sheet 15 will be tilted inside the fixing groove 16. In this way, the thermal sheet 15 will drive the supporting sheet 13 to slide along the inside of the telescopic groove 14, so that the supporting sheet 13 will be detached from the bottom of the support rod 10. At this time, the support rod 10 picks up the supporting force on the lower pressure plate 7 to ensure that the cutting plate 6 can quickly cut off the connecting sleeve 2, and the support rod 10 slides into the sliding groove 11 after losing the support of the support sheet 13. The limit block 12 can limit the support rod 10, thereby achieving the effect of assisting the cutting plate 6 to quickly cut off the connecting sleeve 2, thereby improving the protection effect of the circuit short circuit.

[0025] Working principle: first put the mounting tube 4 and the mounting sleeve 3 on one end of the wiring harness, and then put the insulating sleeve main body 1 on the other end that needs to be connected. At this time, rotate the connecting sleeve 2 to connect the insulating sleeve main body 1 and the mounting sleeve 3. When a short circuit occurs in the line, high temperature will be generated at the connection. At this time, the connection of the connecting sleeve 2 is thinner, and the weak part becomes soft, and the worm spring rod 8 will apply rotational force to the lower pressure plate 7. At this time, the lower pressure plate 7 can drive the cutting plate 6 to press down, allowing the cutting plate 6 to cut the connecting sleeve 2 along the fracture groove 5. In this way, the short-circuited line can be quickly cut off, thereby quickly processing and achieving the effect of quickly disconnecting the line connection. This solves the problem that high temperature will be generated at the connection when a short circuit occurs in the circuit, causing problems in line transmission and causing irreversible damage to the equipment, thereby improving the line protection effect. The mounting tube 4 and the mounting sleeve 3 are directly put on one end of the wiring harness, and the mounting tube 4 is fixed to one end of the line with hot melt glue. Then the insulating sleeve main body 1 is put on the outside of the other wiring harness, and the insulating sleeve main body 1 is pinched away from the end of the mounting sleeve 3. When the support plate 6 is disconnected from the support plate 7, the support plate 6 can be connected to the support plate 7 by the support rod 10, and the support plate 6 can be connected to the support plate 7 by the support rod 10. When the support plate 6 is disconnected from the support plate 7, the support plate 6 can be connected to the support plate 7 by the support rod 10. When the support plate 6 is disconnected from the support plate 7, the support plate 6 can be connected to the support plate 7 by the support rod 10.
