For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0029] Combination Figures 1 to 6As shown, the present application provides a socket 100. In some embodiments, the socket 100 can be used to be fixed on the wall panel of the device. In some embodiments, the socket 100 is used to dock with a plug. A portion of the plug is accommodated in the socket 100 along the access direction F1 of the socket 100. In some embodiments, the docking between the socket 100 and the plug is used to achieve the transmission of electrical energy or electrical signals. Specifically, the wall panel can be a component panel of the outer shell or cabinet of the device. In some embodiments, the wall panel can be a panel, side panel or top panel of the cabinet. In other embodiments, the wall panel can be a partition panel inside the outer shell or cabinet. In some other embodiments, the wall panel can also be other structural parts in the device specifically used to install the socket 100.

[0030] In some embodiments, in combination Figure 1 and Figure 4 As shown, the socket 100 includes a plurality of contact terminals 50 and an insulator 40. The plurality of contact terminals 50 are inserted into the insulator 40. The insulator 40 covers the outer circumference of the contact terminal 50 to maintain insulation between different contact terminals 50. In some embodiments, one end of the contact terminal 50 is used to electrically connect with a conductive component in the plug, and the other end of the contact terminal 50 is exposed from the insulator 40 and connected to a conductive part of the electrical cable.

[0031] In some embodiments, in combination Figures 3 to 5 As shown, the socket 100 includes: a shell 20 and a sealing gasket 30. The shell 20 includes a flange portion 21 and a peripheral wall portion 22. The flange portion 21 is provided with a face side 211 and a back side 212 that are opposite to each other along the access direction F1. The peripheral wall portion 22 is connected to the back side 212 of the flange portion 21. A positioning groove 213 is provided on the back side 212 of the flange portion 21. The positioning groove 213 is recessed relative to the peripheral portion 214 of the back side 212, and the positioning groove 213 is arranged along the periphery of the peripheral wall portion 22. The sealing gasket 30 includes a main cushion layer 31 and a limiting layer 32 connected to one side of the main cushion layer 31. The main cushion layer 31 and the limiting layer 32 are sleeved outside the peripheral wall portion 22. The limiting layer 32 is accommodated in the positioning groove 213, and the shape and size of the limiting layer 32 correspond to the positioning groove 213 respectively. The area of ​​the main cushion layer 31 is larger than the area of ​​the positioning groove 213.

[0032] Specifically, when the socket 100 needs to be installed on a device, the flange portion 21 is installed outside the wall plate of the device. The back side 212 of the flange portion 21 faces the wall plate. The sealing gasket 30 is arranged between the back side 212 of the flange portion 21 and the wall plate to fill the gap between the flange portion 21 and the wall plate, prevent the liquid from contacting the contact terminal 50 installed in the housing 20 through the gap between the flange portion 21 and the wall plate, and prevent the liquid from flowing into the inside of the device through the gap between the flange portion 21 and the wall plate. At the same time, since a positioning groove 213 is provided on the back side 212 of the flange part 21, the positioning groove 213 is recessed relative to the outer peripheral part 214 of the back side 212, and the limiting layer 32 is accommodated in the positioning groove 213, the shape and size of the limiting layer 32 respectively correspond to the positioning groove 213. Therefore, when the flange part 21 is fixed on the wall panel of the equipment under the extrusion of the fastener, the positioning groove 213 can limit the position deviation of the limiting layer 32, thereby avoiding a large gap between the sealing gasket 30 and the peripheral wall part 22 due to excessive position deviation of the sealing gasket 30 relative to the flange part 21, which is beneficial to ensure the waterproofness between the sealing gasket 30 and the shell 20.

[0033] Specifically, combined Figure 6 As shown, since the area of ​​the main cushion layer 31 is larger than the area of ​​the positioning groove 213, the main cushion layer 31 can exceed the edge range of the limiting layer 32, and the portion of the main cushion layer 31 that exceeds the limiting layer 32 is in contact with the flange portion 21, thereby increasing the contact area between the sealing gasket 30 and the flange portion 21, which is beneficial to improving the waterproof effect of the sealing gasket 30. In some embodiments, the relative direction between the main cushion layer 31 and the limiting layer 32 is parallel to the access direction F1. The face side 211 of the flange portion 21 points to the back side 212 along the access direction F1.

[0034] In some embodiments, in combination Figure 3 As shown, the insulator 40 is positioned and accommodated in the housing 20. Specifically, the flange portion 21 and the peripheral wall portion 22 surround the outer peripheral side of the insulator 40, thereby providing protection for the insulator 40. The peripheral portion 214 of the back side 212 is the portion of the flange portion 21 within the outer peripheral edge of the back side 212.

[0035] In some embodiments, the insulator 40 may be positioned and accommodated in the housing 20 by snapping. In other embodiments, the insulator 40 may be positioned and accommodated in the housing 20 by interference fit with the inner circumference of the housing 20. In still other embodiments, the insulator 40 may be positioned and accommodated in the housing 20 by threading with the inner circumference of the housing 20.

[0036] In some embodiments, in combination Figure 4 and Figure 5As shown, the flange portion 21 is provided with a plurality of first mounting holes 215. The first mounting holes 215 are connected between the face side 211 and the back side 212. In some embodiments, a through opening and a plurality of screw holes are reserved on the wall panel of the device. The plurality of screw holes are arranged around the through opening. When the socket 100 needs to be fixed on the wall panel, the back side 212 of the flange portion 21 is directed toward the wall panel, and the peripheral wall portion 22 is inserted into the through opening. The angle of the flange portion 21 is adjusted so that the first mounting hole 215 is aligned with the screw hole. Thereafter, the fastener is inserted into the first mounting hole 215 and the screw hole, and the end of the fastener abuts against the surface of the flange portion 21 around the first mounting hole 215, so that the socket 100 can be fixed on the wall panel. In some embodiments, the fastener is a screw. In other embodiments, the socket 100 can also be fixed to the wall panel using bolts and nuts.

[0037] In some embodiments, in combination Figures 4 to 6 As shown, the positioning groove 213 is arranged to avoid the first mounting hole 215, so that the thickness of the flange part 21 near the first mounting hole 215 will not decrease due to the setting of the positioning groove 213. The part of the flange part 21 near the first mounting hole 215 has a greater structural strength, preventing the flange part 21 from breaking under the holding pressure of the fastener.

[0038] In some embodiments, in combination Figure 3 and Figure 4 As shown, the housing 20 is provided with a slot 23 penetrating the flange portion 21. Along the direction from the back side 212 to the front side 211, the slot 23 has a first slot section 231 and a second slot section 232 in sequence, and the space of the second slot section 232 is stepped and expanded relative to the first slot section 231, so that a stepped transition surface is formed at the intersection of the first slot section 231 and the second slot section 232. Specifically, the first slot section 231 is connected between the second slot section 232 and the back side 212 of the flange portion 21.

[0039] In some embodiments, in combination Figure 3 and Figure 6As shown, the sealing gasket 30 is connected with a buckle body 33. The buckle body 33 includes a transition section 331 and a buckle head 332. The transition section 331 is connected between the buckle head 332 and the sealing gasket 30, and the transition section 331 is accommodated in the first slot section 231. The buckle head 332 is accommodated in the second slot section 232, and the minimum width of the buckle head 332 is greater than the minimum width of the first slot section 231. Specifically, due to the space limitation of the first slot section 231, the buckle head 332 of the buckle body 33 cannot pass through the first slot section 231 of the slot 23 without being greatly deformed, so that the buckle head 332 is restricted in the second slot section 232, so that the sealing gasket 30 can be kept connected with the housing 20. In the case where the sealing gasket 30 needs to be removed, the buckle head 332 can also be pulled with a certain force to bend relative to the transition section 331, so that the buckle head 332 passes through the first slot section 231 and the sealing gasket 30 is separated from the housing 20. In some embodiments, the transition section 331 and the buckle section 332 are bent.

[0040] In some embodiments, in a plane projection perpendicular to the access direction F1, when the outer edge of the buckle head 332 is circular, the minimum width of the buckle head 332 is the diameter. When the outer edge of the buckle head 332 is rectangular, the minimum width of the buckle head 332 is the width of the rectangle. When the outer edge of the buckle head 332 is elliptical, the minimum width of the buckle head 332 is the minor axis of the ellipse. Specifically, the minimum width of the first slot section 231 can be understood in the same way.

[0041] In some embodiments, in combination Figure 5 and Figure 6 As shown, the extension part 311 of the main cushion layer 31 exceeds the edge of the limiting layer 32. The shape of the extension part 311 of the main cushion layer 31 corresponds to the peripheral part 214 of the back side 212. Specifically, since the extension part 311 of the main cushion layer 31 corresponds to the peripheral part 214 of the back side 212, the extension part 311 of the main cushion layer 31 can fully fit with the peripheral part 214 of the flange part 21, thereby increasing the fitting area between the main cushion layer 31 and the flange part 21, which is beneficial to further improve the waterproof effect of the sealing gasket 30.

[0042] Specifically, the main cushion layer 31 further includes a main body portion, and the shape of the main body portion corresponds to the shape of the limiting layer 32. The extension portion 311 extends along the outer periphery of the main body portion.

[0043] In some embodiments, in combination Figure 5 and Figure 6As shown, the limiting layer 32 is connected to a first circumferential convex portion 34. The thickness and width of the first circumferential convex portion 34 are smaller than the limiting layer 32. The first circumferential convex portion 34 is arranged to protrude relative to the surface of the limiting layer 32. Specifically, the first circumferential convex portion 34 is arranged around the outer periphery of the peripheral wall portion 22. Since the thickness and width of the first circumferential convex portion 34 are smaller than the limiting layer 32, the first circumferential convex portion 34 is more likely to undergo compression deformation relative to the limiting layer 32. In the relative direction of the flange portion 21 and the limiting layer 32, the first circumferential convex portion 34 can more reliably form a sealed separation between the outer peripheral side and the middle part of the flange portion 21, preventing liquid from flowing between the flange portion 21 and the limiting layer 32. Specifically, the first circumferential convex portion 34 is arranged to protrude relative to the limiting layer 32 on the surface facing away from the main cushion layer 31.

[0044] In some embodiments, in combination Figure 3 and Figure 4 As shown, the main cushion layer 31 is connected with a second circumferential convex portion 35. The thickness and width of the second circumferential convex portion 35 are smaller than those of the main cushion layer 31, and the second circumferential convex portion 35 is arranged to be raised relative to the surface of the main cushion layer 31. Specifically, the second circumferential convex portion 35 is arranged around the outer periphery of the peripheral wall portion 22. Since the thickness and width of the second circumferential convex portion 35 are smaller than those of the main cushion layer 31, the second circumferential convex portion 35 is more likely to be compressed and deformed relative to the main cushion layer 31. In the relative direction between the wall plate and the main cushion layer 31, the second circumferential convex portion 35 can more reliably form a sealed separation between the outer peripheral side and the middle part of the main cushion layer 31, preventing liquid from flowing between the wall plate and the main cushion layer 31. Specifically, the second circumferential convex portion 35 is arranged to be raised relative to the main cushion layer 31 and is opposite to the surface of the limiting layer 32.

[0045] In some embodiments, in combination Figures 4 to 6 As shown, the sealing gasket 30 is provided with a plurality of second mounting holes 36. The second mounting holes 36 are through both sides of the sealing gasket 30 along the access direction F1. Specifically, when the socket 100 needs to be fixed on the wall plate, the fasteners pass through the first mounting hole 215, the second mounting hole 36 and the screw hole in sequence, so that the sealing can be limited to an angle relative to the flange portion 21. In some embodiments, the second mounting holes 36 are provided in the main cushion layer 31.

[0046] In some embodiments, in combination Figure 4 As shown, the second circumferential convex strip portion 35 is also arranged around the outer periphery of the second mounting hole 36, so as to prevent liquid from entering the interior of the device through the gap between the main cushion layer 31 and the wall plate, and the gap between the screw hole and the fastener.

[0047] In some embodiments, in combination Figure 2 and Figure 3As shown, the housing 20 further includes an outer cylinder portion 24. The outer cylinder portion 24 is connected to the surface side 211 of the flange portion 21. Specifically, the outer cylinder portion 24 surrounds the outer circumference of the insulator 40, so as to provide protection for the insulator 40.

[0048] In some embodiments, in combination Figures 1 to 3 As shown, the socket 100 further includes a cover body 60 and a connecting strip 61. The connecting strip 61 is connected between the sealing gasket 30 and the cover body 60. The cover body 60 is used to cover the port of the outer cylinder 24. Specifically, the outer cylinder 24 is arranged outward relative to the flange part 21. When the socket 100 does not need to be connected to the plug temporarily, by allowing the cover body 60 to cover the port of the outer cylinder 24, the cover body 60 can cooperate with the outer cylinder 24 to form a closed space, thereby preventing the insulator 40 and the contact terminal 50 in the outer cylinder 24 from contacting with liquid or dust. Since the connecting strip 61 is provided between the sealing gasket 30 and the cover body 60, when the socket 100 needs to be connected to the plug, the cover body 60 is suspended and connected to the sealing gasket 30 through the connecting strip 61, thereby preventing the cover body 60 from being lost. In some embodiments, the cover body 60 is used to be sleeved on the outer periphery of the outer cylinder 24.

[0049] In some embodiments, in combination Figure 4 As shown, at least two notches 216 are formed on the peripheral portion 214 of the back side 212 of the flange portion 21, and different notches 216 are arranged at intervals. The positioning groove 213 extends to the peripheral edge of the back side 212 through the notches 216. A stopper 217 is formed between the two notches 216 of the flange portion 21. The stopper 217 at least abuts against the outer edge of the limiting layer 32. In other embodiments, by increasing the height of the stopper 217 relative to the bottom surface of the positioning groove 213, the stopper 217 can be simultaneously abutted against the outer edges of the limiting layer 32 and the main cushion layer 31. In some embodiments, according to the width of the back side 212 of the flange portion 21, the number of the notches 216 can be three, four or more.

[0050] Specifically, when the cover 60 is closed over the port of the outer cylinder 24, the connecting strip 61 needs to be wound from the back side 212 of the flange 21 to the front side of the flange 21. In the process of operating the cover 60, it is often easy to accidentally pull the connecting strip 61. Since the connecting strip 61 is connected to the sealing gasket 30, the position of the sealing gasket 30 relative to the flange 21 may be offset due to the pulling of the connecting strip 61, resulting in a gap between the sealing gasket 30 and the flange 21 due to displacement, and liquid may enter the inside of the device through the gap.

[0051] In some embodiments, in combination Figure 1 and Figure 5As shown, the connecting strip 61 includes a main strip portion 611 and at least two branch portions 612. The branch portion 612 is connected between one end of the main strip portion 611 and the limiting layer 32, and the branch portion 612 and the limiting layer 32 are connected through the notch 216. Specifically, the other end of the main strip portion 611 is connected to the cover body 60. When the connecting strip 61 is pulled, the pulling direction is generally inclined toward the surface side 211 of the flange portion 21. When the connecting strip 61 is connected to the limiting layer 32, the limiting layer 32 can be pressed against the flange portion 21. Since one end of the main strip portion 611 is connected to the limiting layer 32 through at least two branch portions 612, and the branch portion 612 is connected to the limiting layer 32 through the notch 216, when there is a stopper 217 between the two notches 216, the portion of the sealing gasket 30 pulled by the two branch portions 612 will be limited by the stopper 217, thereby preventing the edge of the sealing gasket 30 from being excessively deformed and preventing the sealing gasket 30 from having a gap with the flange portion 21 due to the pulling of the connecting strip 61. More specifically, since the sealing gasket 30 has a greater thickness in the area corresponding to the limiting layer 32, when the branch portion 612 is connected to the limiting layer 32, the branch portion 612 and the sealing gasket 30 can have a greater connection strength, which is conducive to preventing the connection between the connecting strip 61 and the sealing gasket 30 from being broken. In some embodiments, the number of notches 216 corresponds to the number of branches 612.

[0052] Specifically, since the limiting layer 32 is closer to the flange portion 21 than the main cushion layer 31, the limiting layer 32 is tightly attached to the flange portion 21 when pulled. Therefore, even if the stop block 217 only abuts against the limiting layer 32, the stop block 217 can reliably limit the deformation of the sealing gasket 30 under pulling.

[0053] In some embodiments, in combination Figure 1 and Figure 2 As shown, the sealing gasket 30, the connecting strip 61 and the cover body 60 are integrally connected, so as to simplify the assembly of the socket 100. In some embodiments, the sealing gasket 30, the connecting strip 61 and the cover body 60 are made of silicone, rubber or other flexible materials. In some embodiments, the buckle body 33, the sealing gasket 30, the connecting strip 61 and the cover body 60 are integrally connected. In other embodiments, the connecting strip 61 can also be a chain connected between the cover body 60 and the sealing gasket 30.

[0054] The above implementation modes are merely descriptions of the preferred implementation modes of the present application, and are not intended to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present application.
