[0046] Specific embodiment 1, as shown in Figure 1 、 Figure 2 and Figure 3 , a gasket for compressor, for being installed between the upper shell cover 200 of compressor and terminal box cover 300, the terminal box cover 300 includes box body 310 and terminal lead-out nozzle 320 connected to one side of box body 310, the gasket 100 includes:

[0050] Second limiting portion 140, the second limiting portion 140 is integrally formed on the upper surface of the sheet body 110, and is used for stopping and limiting the terminal lead-out nozzle 320 of the terminal box cover 300 in the circumferential direction of the bolt sleeve pipe 120.
[0051] Preferably, as shown in Figure 2 and Figure 3As shown, the second limiting part 140 is a limiting convex block integrally formed on the upper surface of the sheet body 110, which is located on one side or both sides of the width direction of the wire leading-out nozzle 320, so that in the circumferential direction of the bolt sleeve 120, the limiting convex block forms a stop cooperation with the wire leading-out nozzle 320, thereby preventing the wire leading-out nozzle 320 from rotating around the fixing bolt 210 on the top of the upper shell cover 200, and preventing the wire box cover 300 from being offset.
[0052] More preferably, the number of limiting convex blocks is two, and the two limiting convex blocks are located on both sides of the width direction of the wire leading-out nozzle 320, and the horizontal distance between the two limiting convex blocks is greater than the width dimension of the wire leading-out nozzle 320.
[0053] Specific embodiment 2, as Figures 1-5 shown, a protective cover connecting structure fixed on the upper shell cover 200 of the compressor, comprising the above-mentioned gasket 100 for the compressor, and the wire box cover 300 and the fastening nut 400.
[0054] The upper shell cover 200 is fixedly connected with the fixing bolt 210 and the wire seat 220 on the top thereof, and the wire column assembly is installed on the wire seat 220; the wire box cover 300 comprises a box body 310 and a wire leading-out nozzle 320 connected to one side of the box body 310.
[0055] The gasket 100 is installed between the upper shell cover 200 and the wire box cover 300, the bolt sleeve 120 is sleeved outside the fixing bolt 210, the fastening nut 400 is threadedly connected with the top end of the fixing bolt 210, and the fastening nut 400 is loaded above the wire box cover 300, and the lower surface of the wire box cover 300 is tightly fitted with the upper surface of the sheet body 110, that is, the lower end surface of the bottom of the wire box cover 300 is tightly fitted with the upper surface of the sheet body 110.
[0056] The first limiting part 130 is sleeved on the bottom of the wire seat 220, and the first limiting part 130 is located between the bottom of the wire seat 220 and the bottom of the box body 310, and the outer circumference of the first limiting part 130 cooperates with the inner circumferential direction of the box body 310, that is, the outer circumferential surface of the limiting convex ring is fitted with the inner surface of the side wall of the box body 310, so as to prevent the box body 310 from rotating around the fixing bolt 210 by the stop action of the limiting convex ring on the box body 310.
[0057] The wire leading-out nozzle 320 is located between the two second limiting parts 140, that is, the wire leading-out nozzle 320 of the wire box cover 300 is located between the two limiting convex blocks, so as to prevent the wire leading-out nozzle 320 from rotating around the fixing bolt 210 by the stop action of the limiting convex block on the wire leading-out nozzle 320.
[0058] In another specific embodiment, as Figure 4As shown, the upper end surface of the bolt sleeve 120 is attached to the top inner surface of the box body 310.
[0059] Thus, the fixed bolt 210 is completely sleeved in the bolt sleeve 120 in the cavity surrounded by the junction box cover 300 and the gasket 100, which not only prevents the wire harness from contacting the fixed bolt 210 and causing electric leakage and safety accidents, but also reduces the activity space of the wire harness and improves the shaking of the wire harness in the junction box cover 300, thereby improving the damage of the wire harness in the shaking and pulling process.
[0060] Specifically, as shown in Figure 1 and Figure 3 The axial dimension of the bolt sleeve 120 is a, that is, the dimension of the bolt sleeve 120 in the vertical direction is a; the height dimension of the box body 310 of the junction box cover 300 is e, that is, the vertical distance between the upper surface of the top of the box body 310 and the lower surface of the bottom is e, and a = e - the thickness dimension of the top wall.

[0062] Thus, during installation, when the junction box cover 300 is deviated, the lower end surface of the box body 310 will be loaded on the upper surface of the first limiting portion 130, at which time, since b > d - e - f > 0, the top of the fixed bolt 210 cannot be extended from the through hole of the box body 310, and the installation work of the fastening nut 400 cannot be performed by the worker, which not only prevents deviation and corrects deviation, but also timely reminds the worker of the deviation phenomenon.
[0063] Compared with the prior art, the present application has at least the following beneficial technical effects:
[0064] The utility model can improve the shaking of the wire harness in the junction box cover, reduce the damage of the wire harness in the shaking and pulling process, and reduce the electric leakage and safety accidents of the wire harness, while avoiding the contact between the wire harness and the metal structure fixed ring bolt on the top of the shell cover in the junction box cover, which can prevent the safety accidents caused by the contact between the wire harness and the fixed bolt.
[0065] The utility model can ensure that the junction box cover is not deviated during installation, so that the junction box cover and the gasket can be installed in place.
[0066] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
