[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 The utility model embodiment is a compressor junction box, which includes a base 1 and a cover plate 13 covering the top of the base 1. Both sides of the base 1 are provided with wire holes 2, and the insides of the two wire holes 2 are inserted with wires 3. The outside of the base 1 and one side of the wire holes 2 are provided with a sealing assembly; the sealing assembly includes a fixed sleeve 4 fixedly connected to the outside of the base 1, a movable sleeve 5 threadedly connected to the outside of the fixed sleeve 4, four guide rods 8 equidistantly and symmetrically fixedly connected to the end of the fixed sleeve 4 away from the base 1, and four limit rods fixedly connected to one end of the guide rod 8. Block 9, a pressure plate 10 slidably connected to the outside of the four guide rods 8, a push plate 6 fixedly connected to the inner surface of the movable sleeve 5 and located between the pressure plate 10 and the fixed sleeve 4, a sealing ring 7 fixedly connected to the end of the fixed sleeve 4 away from the base 1 and located on the inside of the four guide rods 8, and a raised portion 11 formed on the outside of the sealing ring 7, the pushing plate 6 and the pressure plate 10 are both configured as a circular ring structure, and the facing sides of the pushing plate 6 and the pressure plate 10 are in contact with each other, the inner surface of the pressure plate 10 is in contact with the outer surface of the raised portion 11, and the inner surface of the sealing ring 7 is in contact with the outer surface of the wire 3;

[0024] Specifically, after the wire 3 passes through the wire hole 2 and extends to the inside of the base 1 for wiring, the movable sleeve 5 is rotated to move outside the fixed sleeve 4. When the movable sleeve 5 moves, it drives the push plate 6 to move. The movement of the push plate 6 can better drive the pressure plate 10 to slide on the outside of the guide rod 8. The movable pressure plate 10 moves to the position of the raised portion 11 of the sealing ring 7. Under the action of the pressure plate 10, the raised portion 11 can be squeezed so that the raised portion 11 of the sealing ring 7 is tightly fitted with the outside of the wire 3. Therefore, under the action of the sealing ring 7, the side of the wire 3 located on the outside of the base 1 can be sealed, which can effectively prevent moisture or liquid from flowing into the inside of the base 1 and affecting the internal wiring, thereby improving the protection effect of the junction box and making it safer to use.

[0025] The cover plate 13 is fixedly connected to the top of the base 1 through multiple connecting parts, and a sealing gasket 12 is provided between the top of the base 1 and the cover plate 13. Specifically, when the cover plate 13 closes the base 1, the sealing gasket 12 can well seal the connection between the cover plate 13 and the base 1 to ensure a good sealing environment inside the junction box.

[0026] The base 1, cover plate 13, fixed sleeve 4 and movable sleeve 5 are all made of stainless steel. Specifically, the base 1, cover plate 13, fixed sleeve 4 and movable sleeve 5 made of stainless steel have good corrosion resistance. In the compressor environment, the corrosion-resistant junction box helps prevent damage or malfunction caused by liquids or other chemicals.

[0027] The connecting member is a bolt 14 threadedly connected to the inside of the cover plate 13, and the bottom of the bolt 14 is threadedly connected to the inside of the base 1. The cover plate 13 and the base 1 are fixedly connected by the bolt 14, and the connection is stable and easy to assemble and disassemble.

[0028] The heads of the plurality of bolts 14 are all interference-fitted with caps 15 , which can protect the exposed heads of the bolts 14 to reduce the corrosion of the external humid environment on the bolts 14 and reduce the impact on the smooth removal of the bolts 14 .

[0029] The outer surfaces of the two movable sleeves 5 are both provided with anti-skid textures, which can increase the friction between the operator's hand and the movable sleeve 5, so as to facilitate stable operation of the movable sleeve 5 for rotation.

[0030] Working principle: After the wire 3 passes through the wire hole 2 and extends to the inside of the base 1 for wiring, the movable sleeve 5 is rotated to move outside the fixed sleeve 4. When the movable sleeve 5 moves, it drives the push plate 6 to move. The movement of the push plate 6 can better drive the pressure plate 10 to slide on the outside of the guide rod 8. The movable pressure plate 10 moves to the position of the raised portion 11 of the sealing ring 7. Under the action of the pressure plate 10, the raised portion 11 can be squeezed to make the raised portion 11 of the sealing ring 7 tightly fit with the outside of the wire 3. Therefore, under the action of the sealing ring 7, the side of the wire 3 located on the outside of the base 1 can be sealed, which can effectively prevent moisture or liquid from flowing into the inside of the base 1 and affecting the internal wiring, thereby improving the protection effect of the junction box and making it safer to use.

[0031] When the cover plate 13 closes the base 1 , the sealing gasket 12 can well seal the connection between the cover plate 13 and the base 1 to ensure a good sealing environment inside the junction box.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
