[0002] The compressor gasket is an indispensable part in the installation and operation of the compressor, and it is also a protective component. The main function of the gasket is to prevent the air and other media from entering the compressor to ensure the normal operation of the compressor. It can not only ensure that the gap and contact surface of the transmission part are appropriate, which is convenient for installation and disassembly, but also effectively prevent the loosening and leakage of the transmission system. The gasket can also increase the bearing support area and make the surface contact between the compressor shoe and the rotor closer.

[0003] The gasket is often assembled with the junction box during use. However, the current compressor junction box outlet is an open structure. After the power cord is led out, rubber mud will be used to seal the open opening. The rubber mud is sealed on the insulating gasket. The opening is closed to prevent rainwater from entering the interior and affecting the normal consolidation of the interior. However, the rubber is in a high temperature state for a long time, and the gasket will become loose after a long period of vibration, resulting in aging, hardening, and easy falling off of the rubber. Utility Model Content

[0033] The utility model is further described in detail below with reference to the accompanying drawings:

[0034] See also Figures 1 to 4 The utility model discloses an insulating gasket for a compressor, comprising a gasket body 1, on which are arranged spaced-apart close holes 1-3 and bolt holes 1-4, a line outlet sealing structure 1-1 is arranged on one side of the close holes 1-3; a through inner cavity 1-1-1 is arranged inside the line outlet sealing structure 1-1, the inner cavity 1-1-1 is used for nesting a power line, and a concave-convex structure is arranged on the inner wall of the inner cavity 1-1-1.

[0035] Furthermore, in this embodiment, the sealing holes 1-3 and the bolt holes 1-4 are inserted into the sealing holes and the bolts 4 on the upper cover of the compressor, thereby fixing the horizontal movement and rotational freedom of the insulating gasket.

[0036] Furthermore, in this embodiment, the specific structure of the outlet sealing structure 1-1 is:

[0037] The outlet sealing structure 1-1 includes a sealing plate body, which is an arched structure, one end of which is fixedly connected to the gasket body 1, and there is a gap between the other end and the gasket body 1. An inner cavity 1-1-1 is formed between the inner wall of the arched structure and the gasket body 1, and the inner cavity 1-1-1 is used to nest the power cord 2.

[0038] Furthermore, the structure of the sealing sheet body may be an inverted U-shaped structure or a polygonal structure, as long as the installation requirements are met.

[0039] Furthermore, the concave-convex structure can be a thread 1-1-3, the thread shape is in contact with the sealing line, and the flame retardant grade reaches UL-5VA level, thereby improving the stability of fixing the power cord 2.

[0040] Furthermore, in this embodiment, the material of the gasket body 1 is EPDM or silicone rubber. When the nut on the upper end of the junction box applies downward pressure, the outlet of the junction box can squeeze the outlet sealing structure downward, thereby improving the stability of the sealing gasket fixation and the junction box assembly and strengthening the tightness of the connection between the two.

[0041] See also Figures 5 and 6 , the assembly principle of this embodiment is:

[0042] The power cord 2 is inserted into the outlet sealing structure 1-1, and the gasket body 1 is installed in place. At this time, the sealing hole 1-3 and the bolt hole 1-4 are inserted into the sealing hole and the bolt 4 on the compressor cover 6, and the junction box cover 3 is pressed on the upper end of the gasket body 1. At this time, the junction box cover 3 is provided with a through hole corresponding to the bolt 4, and an outlet structure corresponding to the outlet sealing structure 1-1. When the junction box cover 3 is installed in place, the outlet structure is sleeved on the outside of the outlet sealing structure 1-1. At this time, the outer wall of the outlet sealing structure 1-1 fits with the inner wall of the outlet structure, and the power cord 2 is restrained. In the outlet sealing structure 1-1, the outlet sealing structure 1-1 can fill the inner cavity of the outlet structure so that the two are in a tight fit. The nut 5 is installed on the bolt 4. The nut 5 applies force to the junction box cover 3 during tightening. The pre-tightening force is transmitted from the junction box cover to the insulating gasket sealing structure. Under the action of the force, the insulating gasket sealing structure is deformed, which makes it easier to fill the gap between the junction box cover and the junction box cover, and the leak is well blocked. In combination with the thread 1-1-3, the thread 1-1-3 fits tightly with the power cord 2 during extrusion deformation, blocking the leak and sealing it well.

[0043] This embodiment also discloses a compressor, comprising the insulating gasket described in any one of the embodiments.

[0044] This embodiment also discloses an air conditioner, comprising the compressor described in any one of the embodiments.
