[0002] In daily life, some electrical appliances and household appliances we use achieve power input connection through power connection components with input sockets and input plugs. However, in outdoor rainy weather or when water splashes or spills in the home, when the input socket and input plug are connected to input power, water can enter the metal conductors of the input socket or input plug through the gaps at the connection point, causing a short circuit. In severe cases, this can lead to fire or electric shock accidents.
[0003] Therefore, a waterproof technical solution is needed to improve the safety of the connection between the input plug and the input socket when power is input. Summary of the Invention
[0004] In view of this, this application provides a waterproof sleeve for input and output sockets, an input socket assembly, and a power input assembly to improve the safety of the input plug and input socket connection when input power is applied.
[0005] This application provides a waterproof sleeve for input / output sockets, used to seal the connection between an input plug and an input socket. The waterproof sleeve for input / output sockets includes a sealing sheet and an annular fitting portion surrounding the sealing sheet. The sealing sheet and the annular fitting portion are integrally formed from an elastic material.
[0006] The annular fitting part is configured to fit onto the input socket, the sealing sheet is used to abut against the front end surface of the input socket, and the sealing sheet is provided with an opening, through which the plug part of the input plug can be inserted into the input socket;
[0007] The opening is configured to be smaller than the cross-section of the plug portion of the input plug, so that when the plug portion is inserted into the input socket, the sealing sheet can elastically wrap around the plug portion.
[0008] In one embodiment, the shape of the opening is configured to conform to the outer periphery of the plug portion of the input plug.
[0009] In one embodiment, the opening is a triangular opening into which a triangular plug portion can be inserted; or, the opening is a plum blossom-shaped opening into which a plum blossom-shaped plug portion can be inserted; or, the opening is a figure-eight-shaped opening into which an figure-eight-shaped plug portion can be inserted.
[0010] In one embodiment, the outline of the opening is offset inward by 1-3 mm compared to the outer peripheral outline of the plug portion.
[0011] In one embodiment, the sealing sheet includes a main sheet and an edge portion connected to the main sheet surrounding the opening, wherein the thickness b2 of the edge portion is less than the thickness b1 of the main sheet.
[0012] In one embodiment, the thickness b2 of the edge portion is 0.5-1.5 mm less than the thickness b1 of the main body.
[0013] In one embodiment, the thickness b1 of the main body is 1-2 mm; and / or, the thickness b2 of the edge portion is 0.5-1 mm; and / or, the width a1 of the edge portion is 1.5-4 mm.
[0014] In one embodiment, the annular fitting includes an annular body extending in a direction perpendicular to the sealing sheet and a covering portion formed by bending inward at the end of the annular body away from the sealing sheet, wherein a receiving space is formed between the sealing sheet and the covering portion, the receiving space being used to receive the front flange of the input socket.
[0015] In one embodiment, the thickness b3 of the annular body is 1-2 mm; and / or, the thickness b4 of the covering portion is 0.5-1 mm; and / or, the width a2 of the covering portion is 1.5-3 mm.
[0016] According to another aspect of this application, an input socket assembly is also provided, including an input socket and a waterproof sleeve for the input / output socket as described above, wherein the waterproof sleeve for the input / output socket is configured to fit over the front end portion of the input socket.
[0017] In one embodiment, the input socket assembly further includes a mounting base with a mounting hole, the input socket being mounted in the mounting hole; wherein the outer peripheral surface of the annular sleeve of the input / output socket waterproof sheath engages and seals with the inner surface of the mounting hole.
[0018] According to another aspect of this application, a power connection assembly is also provided, including the input socket assembly as described above and an input plug that mates with the input socket of the input socket assembly.
[0019] In the technical solution provided in this application, the waterproof sleeves of the input and output sockets are placed on the input socket. When the plug of the input plug is inserted into the input socket through the opening on the sealing sheet 1, since the opening is smaller than the cross-section of the plug, the sealing sheet undergoes elastic deformation and wraps tightly around the outer circumferential surface of the plug when the plug is inserted into the opening. This seals the circumferential gap between the plug and the socket hole, preventing water from entering the socket hole along the circumferential gap. This provides a waterproof function and improves the safety of power supply use.

Detailed Implementation
[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the implementation methods and features in the implementation methods of this application can be combined with each other.
[0055] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0057] When the input socket and input plug are connected, a gap exists between the plug of the input plug and the socket hole. When water comes into contact with this gap, water can enter the input socket through this gap and come into contact with the metal conductor, thus causing a leakage current safety problem. Therefore, this application provides a waterproof sleeve 10 for input / output sockets, see reference... Figures 6-8 The waterproof sleeve 10 of the input / output socket can seal the connection between the input plug 30 and the input socket 20.
[0058] like Figures 1-5 As shown, the input / output waterproof sleeve 10 provided in this application includes a sealing sheet 1 and an annular sleeve 2 surrounding the sealing sheet 1. The sealing sheet 1 and the annular sleeve 2 are integrally molded from an elastic material, such as silicone or rubber.
[0059] The annular sleeve 2 is configured to fit onto the input socket 20, the sealing sheet 1 is used to abut against the front end surface of the input socket 20, and the sealing sheet 1 is provided with an opening 13 for the plug part 301 of the input plug 30 to be inserted into the input socket 20.
[0060] The opening 13 is configured to be smaller than the cross-section of the plug portion 301 of the input plug 30, so that when the plug portion 301 is inserted into the input socket 20, the sealing sheet 1 can elastically wrap around the plug portion 301. The opening 13 being smaller than the cross-section of the plug portion 301 of the input plug 30 means that the dimensions of the opening 13 in all directions are smaller than the dimensions of the plug portion 301 in the corresponding directions when the opening 13 is present.
[0061] When using, first put the annular fitting part 2 of the waterproof sleeve 10 of the input / output socket onto the input socket 20. The state after fitting can be seen from [reference]. Figure 7 The sealing sheet 1 is attached to the front end face of the input socket 20. Then, the plug part 301 of the input plug 30 can be inserted into the input socket 20 through the opening 13 on the sealing sheet 1. Since the opening 13 is smaller than the cross-section of the plug part 301, when the plug part 301 is inserted into the opening 13, the sealing sheet 1 undergoes elastic deformation and wraps tightly around the outer circumferential surface of the plug part 301. This seals the circumferential gap between the plug part 301 and the socket of the input socket 20, preventing water from entering the socket of the input socket 20 along the circumferential gap. This provides waterproofing and improves the safety of power supply use.
[0062] In one embodiment, the shape of the opening 13 is configured to conform to the outer periphery of the plug portion 301 of the input plug 30, and the shape of the opening 13 can be adaptively changed when the outline shape of the plug portion 301 changes. For example... Figures 6-8 In the illustrated embodiment, the input socket 20 is a triangular socket, with opening 13 forming a triangular opening into which the triangular plug can be inserted. Of course, opening 13 can also be other shapes, for example... Figure 26 and Figure 27 In the embodiment shown, the input socket 20 is a quincunx socket, and the opening 13 is a quincunx opening into which the quincunx plug can be inserted; Figure 28 and Figure 29 In the embodiment shown, the input socket 20 is a figure-eight socket, and the opening 13 is a figure-eight opening into which the figure-eight plug can be inserted.
[0063] In one embodiment, the outline of the opening 13 is offset inward by 1-2 mm compared to the outer peripheral outline of the plug portion 301. That is, when the plug portion 301 is inserted into the opening 13, the edge of the opening 13 needs to be deformed to expand outward by 1-2 mm. At this time, the edge of the opening 13 will be tightly wrapped around the plug portion 301 due to the deformation.
[0064] Of course, the smaller the opening 13 is compared to the plug portion 301, the tighter the sealing sheet 1 wraps around the plug portion 301, but the greater the difficulty of inserting the plug portion 301 into the opening 13. Therefore, the size of the opening 13 can be adaptively selected between density and ease of insertion.
[0065] In one embodiment, the sealing sheet 1 includes a main sheet 11 and an edge portion 12 connected to the main sheet 11 surrounding the opening 13. The thickness b2 of the edge portion 12 is less than the thickness b1 of the main sheet 11. By providing an edge portion 12 with a thickness less than that of the main sheet 11, the plug portion 301 can be easily inserted into the opening 13 because the edge portion 12 is easily deformable.
[0066] Optionally, the thickness b2 of the edge portion 12 is 0.5-1.5 mm less than the thickness b1 of the main body 11.
[0067] In one embodiment, reference is made to... Figure 5 The thickness b1 of the main body 11 is 1-2 mm; the thickness b2 of the edge portion 12 is 0.5-1 mm; and the width a1 of the edge portion 12 is 1.5-4 mm.
[0068] In one embodiment, the annular fitting portion 2 includes an annular body 21 extending in a direction perpendicular to the sealing sheet 1, and a covering portion 22 formed by bending inward at the end of the annular body 21 away from the sealing sheet 1. A receiving space is formed between the sealing sheet 21 and the covering portion 22. The receiving space is used to receive the front flange 201 of the input socket 20, that is, the annular fitting portion 2 is used to fit onto the front flange 201. The size of the receiving space needs to be specifically set according to the size of the front flange 201 of the input socket 20 to be used.
[0069] In one embodiment, reference is made to... Figures 14 to 17 and Figure 22 The edge portion 12 may include an annular covering portion 211 extending in a direction perpendicular to the sealing sheet body 1 and toward the covering portion 22. The annular covering portion 211, together with the annular body 21 and the covering portion 22, forms a receiving space for accommodating the front flange 201; that is, the annular fitting portion 2 is used to fit onto the front flange 201. The annular covering portion 211, the annular body 21, and the covering portion 22 can be integrally formed. This design creates a bent receiving space on the edge portion 12, unlike... Figure 2 The middle has a flexible edge portion 12.
[0070] In one embodiment, reference is made to... Figure 5 The thickness b3 of the annular body 21 is 1-2 mm; the thickness b4 of the covering part 22 is 0.5-1 mm; and the width a2 of the covering part 22 is 1.5-3 mm.
[0071] In a more specific embodiment, the input / output connector waterproof sleeve 10 is a sleeve for installation on a triangular input connector. The thickness b1 of the main body 11 of the input / output connector waterproof sleeve is 1.5 mm, the thickness b2 of the edge portion 12 is 0.7 mm, and the width a1 of the edge portion 12 is 2 mm. The thickness b3 of the annular body 21 is 1.5 mm; the thickness b4 of the covering portion 22 is 0.7 mm; and the width a2 of the covering portion 22 is 1.8 mm.
[0072] In another embodiment, the thickness b1 of the main body 11 of the input / output socket waterproof sheath is 2mm, the thickness b2 of the edge portion 12 is 1mm, and the width a1 of the edge portion 12 is 3mm. The thickness b3 of the annular body 21 is 2mm; the thickness b4 of the covering portion 22 is 1mm; and the width a2 of the covering portion 22 is 3mm.
[0073] Based on the size of the front flange 201 of the input socket 20, the size of the accommodating space formed between the sealing plate 21 and the covering part 22 can be determined. The accommodating space can be basically the same as the size of the front flange 201, or, in order to easily fit the waterproof sleeves of the input and output sockets, the accommodating space can be set to be slightly larger than the front flange of the input socket 20.
[0074] Figures 1-8 The waterproof sleeves for the input and output sockets shown are suitable for triangular input sockets. When using other types of input sockets, the shape and parameters of the waterproof sleeves for the input and output sockets can be adapted accordingly.
[0075] According to another aspect of this application, an input socket assembly is also provided, with reference to... Figures 25-29 It includes an input socket 20 and an input / output socket waterproof cover 10 as described above, wherein the input / output socket waterproof cover 10 is configured to fit over the front end of the input socket 20.
[0076] In one embodiment, the input socket assembly may further include a mounting base 40 with mounting holes, see reference. Figure 25 , Figure 27 and Figure 29 The input socket 20 is installed in the mounting hole of the mounting base 40. The outer peripheral surface of the annular fitting portion 2 of the input / output socket waterproof sleeve 10 is sealed to the inner surface of the mounting hole of the mounting base 40 (the sealing mating surface 401 near the opening of the mounting hole in the figure). This prevents water from entering the mounting base through the gap between the input socket 20 and the mounting base 40.
[0077] In another example, refer to Figure 30The outer peripheral surface of the cover portion 22 of the input / output socket waterproof sleeve 10 can be interference-fitted with the protrusion 41 on the sealing mating surface 401 on the mounting base 40, for example, by compression fitting, and the buckle 402 on the mounting base 40 is engaged and fixed with the input socket 20.
[0078] The input socket assembly provided in this application, when the input / output waterproof sleeve 10 is fitted onto the front end of the input socket 20 and the input socket 20 is installed in the mounting base 40, and the adapted input plug 30 is inserted into the socket 20 through the opening 13 on the input / output waterproof sleeve 10, the input / output waterproof sleeve 10 can seal the connection between the input socket 20 and the input plug 30, as well as seal the connection between the input socket 20 and the mounting base 40, thereby effectively improving the safety of the connection between the input plug 30 and the input socket 20 when power is input.
[0079] According to another aspect of this application, a power connection component is also provided, with reference to... Figures 6-8 It includes an input socket 20, an input plug 30 that mates with the input socket 20, and an input / output socket waterproof sleeve 10 as described above. The input / output socket waterproof sleeve 10 is configured to fit over the front end of the input socket 20 to provide waterproofing when the plug portion 301 of the input plug 30 is inserted into the input socket 20.
[0080] The advantages of this power connection assembly are the same as those of the input / output socket waterproof sleeve and input socket assembly mentioned above, and will not be repeated here.
[0081] refer to Figures 9 to 13 In one embodiment, the waterproof sleeve 10 for the input / output socket is not fitted onto the input socket 20, and the input socket 20 is not plugged into the input plug 30. The diagrams and cross-sectional views are shown from different perspectives. Additionally, a three-dimensional structural diagram and cross-sectional view are shown with the waterproof sleeve 10 fitted onto the input socket 20, and the input socket 20 is not plugged into the input plug 30. The waterproof sleeve 10 for the input / output socket can be... Figure 1 As shown in the diagram, during use, the input / output waterproof sleeve 10 is pressed against the input socket 20 after the input plug 30 is inserted into it, causing the input / output waterproof sleeve 10 to fit tightly against the front end of the input socket 20. In this way, the input plug 30, through the process of installing the input socket 20, presses the input / output waterproof sleeve 10 to create a seal, completing the assembly and effectively improving the waterproof performance.
[0082] refer to Figures 18 to 22In another embodiment, the waterproof sleeve 10 of the input / output socket is not fitted onto the input socket 20, and the input socket 20 is not plugged into the input plug 30. The embodiments also include structural schematic diagrams and cross-sectional views from different perspectives, as well as three-dimensional structural schematic diagrams and cross-sectional views of the input / output socket waterproof sleeve 10 fitted onto the input socket 20, and the input socket 20 not plugged into the input plug 30. The waterproof sleeve 10 of the input / output socket can be... Figure 14 As shown in the structure, when in use, the edges of the input / output socket waterproof sleeve 10 are sealed by elastic deformation when fitted onto the input socket 20, thus completing the assembly and effectively improving the waterproof effect.
[0083] In another example, Figure 23 and Figure 24 The diagram and sectional view show the structure of the input / output waterproof sleeve 10 fitted onto the input socket 20, with the input plug 30 inserted into the input socket 20. The structure of the input / output waterproof sleeve 10 can be designed with a bent, space-accommodating design (e.g.,...). Figure 1 ) or has a flexible edge (e.g. Figure 14 Alternatively, the assembly and sealing can be completed by the input plug 30 being pressed into the input socket 20 to achieve a waterproof effect.

Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
