[0030] Example 1
[0031] Combination Figure 1 and Figure 2 As shown, a waterproof sealing assembly provided in this embodiment is connected with the charging interface of the socket to provide waterproof and sealed protection for the charging interface.
[0032] Specifically, combined Figure 4 As shown, a waterproof sealing component includes a protective member 1, which includes a bottom surface, an outer ring 11 surrounding the bottom surface, and an inner ring 12 located inside the outer ring 11, with a gap 1 between the outer ring 11 and the inner ring 12, and the inner ring 12 surrounds a protective cavity, and two connectors 13 are protrudingly arranged on the bottom surface of the protective cavity.
[0033] The waterproof sealing component is used to cooperate with and connect to the socket 2. The socket 2 includes a base and a housing 21 connected to the base. An installation platform is provided inside the housing 21, and there is a second gap between the housing 21 and the installation platform. At least one plug cavity 22 is recessed on the installation platform. When the socket 2 is connected to the waterproof sealing component, the plug 13 is connected to the plug cavity 22 in a matching manner. The housing 21 is located in the first gap between the outer ring 11 and the inner ring 12, and the inner ring 12 is located in the second gap between the housing 21 and the installation platform. A charging interface is formed inside the housing 21. Since the housing 21 is located in the first gap between the outer ring 11 and the inner ring 12, the charging interface is completely protected inside the waterproof sealing component, thereby externally sealing and protecting the charging interface to protect the internal electrical connections and electronic components from damage.
[0034] In this embodiment, the waterproof sealing component is a soft rubber sealing structure, made of an elastic material, such as rubber material, etc. Only the plug 13 protrudes on the bottom surface of the protection cavity. The plug 13 is connected to the plug cavity 22 in a matching manner. The entire installation platform is located in the protection cavity inside the inner ring 12. The end face of the installation platform is in large-area contact and sealing with the bottom surface of the protection cavity, ensuring the sealing quality; moreover, when the waterproof sealing component is pressed down, the end face of the installation platform is in contact and cooperation with the bottom surface of the protection cavity, so that there is no obvious void in the protection cavity, improving the texture of the protection part 1.
[0035] In other cases, the number of plugs 13 can also be set to other values, depending on the matching requirements with the plug cavities 22.
[0036] As a further improvement, the inside of the plug 13 is hollow, and cross-shaped reinforcing ribs 131 are provided inside the plug 13. The provision of the reinforcing ribs 131 is beneficial to improving the structural strength of the plug 13. Specifically, in combination with Figure 4 the view orientation in the figure, two reinforcing ribs 131 are provided inside each plug 13, and the two reinforcing ribs 131 are arranged in a horizontal and vertical cross manner. By regularly setting the direction of the reinforcing ribs 131, the structural strength of each part of the plug 13 can be made uniform, so that when the plug 13 is pressed into the plug cavity 22, the pressing effect is better, and the plug 13 is prevented from skewing.
[0037] Combined with Figure 3 as shown, a number of first locking protrusions 121 are circumferentially and spacedly protruded on the outer side of the inner ring 12, and the setting positions and the number of the first locking protrusions 121 on the opposite side surfaces of the outer side of the inner ring 12 correspond to each other.
[0038] In a preferred embodiment, the first locking protrusion 121 is in the shape of a protruding circular bulge, and the protruding height of the first locking protrusion 121 is 0.3 mm. When the receptacle 2 is connected to the waterproof sealing assembly, the housing 21 is located at a gap between the outer ring 11 and the inner ring 12. The outer side of the inner ring 12 is in mating connection with the inner side of the housing 21. There is an interference amount of 0.3 mm between the first locking protrusion 121 and the housing 21, so that the housing 21 generates a radial thrust on the inner ring 12 through the first locking protrusion 121. On the one hand, it makes the inner ring 12 centered and avoids deflection. On the other hand, it makes the inner ring 12 stably and firmly connected to the housing 21 in cooperation, improving the sealing effect.
[0039] Combined Figure 3 with Figure 5 As shown, mounting posts 14 are connected to both sides of the outer ring 11. One end of the mounting post 14 is connected to the end face of the outer ring 11, and the other end extends in a direction away from the bottom surface. A number of second locking protrusions 141 are protrudingly arranged on the front and rear two side surfaces of the outer side of the mounting post 14 (taking Figure 3 the view orientation in the figure as an example), and the arrangement positions and the number of the second locking protrusions 141 on both side surfaces correspond to each other; the protruding height of the second locking protrusions 141 is 0.3 mm. A groove is formed by the depression on the side of the mounting post 14 away from the protection cavity.
[0040] Two limiting posts 23 are respectively arranged on the opposite sides of the outer side of the housing 21 of the receptacle 2, and an installation space is formed between the two limiting posts 23. After the receptacle 2 is connected to the waterproof sealing assembly, the mounting post 14 is installed into the installation space between the two limiting posts 23. The second locking protrusion 141 is located on the side surface where the mounting post 14 contacts the limiting post 23. After the mounting post 14 is completely installed into the installation space between the two limiting posts 23, the connection between the receptacle 2 and the waterproof sealing assembly is completed, which is convenient to indicate from the outside that the waterproof sealing assembly is assembled in place.
[0041] At the same time, the second locking protrusion 141 is provided. The second locking protrusion 141 is also in the shape of a protruding circular bulge. When the mounting post 14 is in contact and cooperation with the limiting post 23, there is an interference amount of 0.3 mm between the two, so that the limiting post 23 can firmly clamp the mounting post 14 and prevent the mounting post 14 from coming out. The mounting post 14 has a groove, which makes the mounting post 14 more easily deformed during the installation process and is convenient for installation.
[0042] It should be noted that in other cases, the protruding heights of the first locking protrusion 121 and the second locking protrusion 141 can also be set to 0.15 mm, 0.5 mm, etc. The protruding heights of the first locking protrusion 121 and the second locking protrusion 141 can be equal or unequal, but the height range of the first locking protrusion 121 and the second locking protrusion 141 is 0.15 - 0.5 mm. On the one hand, it can generate a radial thrust on the receptacle 2, and on the other hand, it also enables the protection part 1 and the receptacle 2 to be connected in cooperation.
[0043] Combined with Figure 3 and Figure 6 As shown, three positioning rods 112 are arranged at intervals on one side inside the outer ring 11. An anti-misalignment rod 111 is connected to one of the positioning rods 112 that deviates from the center line of the protection cavity. The height of the anti-misalignment rod 111 is 10 mm. Taking Figure 4 the view orientation in [description] as an example, an anti-misalignment rod 111 is connected to one of the positioning rods 112 that deviates from the vertical center line of the protection cavity. A first installation position 24 is correspondingly arranged on the outer side of the housing 21 of the socket 2, and the anti-misalignment rod 111 is correspondingly installed in the first installation position 24 to prevent the waterproof sealing component from being installed reversely. The height of the anti-misalignment rod 111 can also be set to other values, such as 3 mm, 23 mm, etc. Generally, the height range of the anti-misalignment rod 111 is 3 - 23 mm, which is conducive to visual observation from the outside while preventing reverse installation.
[0044] In other cases, the number of the positioning rods 112 can also be set to other numbers. However, preferably, the number of the positioning rods 112 is set to an odd number, which is convenient for setting the anti-misalignment rod 111 to prevent the waterproof sealing component from being installed reversely.
[0045] In a preferred case, the height of the outer ring 11 extending away from the bottom surface is higher than the height of the inner ring 12 extending away from the bottom surface. After the socket 2 is connected to the waterproof sealing component in a matching manner, the outer ring 11 is located outside the housing 21 and covers the entire charging interface, which can improve the protection effect of the waterproof sealing component.
[0046] The protective part 1 in this embodiment is integrally formed, for example, it can be made by mold injection. The integrally formed protective part 1 can make the connection between the various components in the waterproof sealing component more firm and also make the appearance of the waterproof sealing component better.
[0047] Embodiment 2
[0048] Combined with Figure 1 and Figure 2 As shown, this embodiment provides a plugging device, which includes a socket 2 and the waterproof sealing component in Embodiment 1 that are connected in a matching manner. The socket 2 includes a base and a housing 21 connected to the base. An installation table is arranged inside the housing 21, and there is a second gap between the housing 21 and the installation table. Two plugging cavities 22 are recessed on the installation table, and the number of the plugging cavities 22 corresponds to the number of the plugs 13. When the socket 2 is connected to the waterproof sealing component, the plugs 13 are connected to the plugging cavities 22 in a matching manner. The housing 21 is located at the first gap between the outer ring 11 and the inner ring 12, and the inner ring 12 is located at the second gap between the housing 21 and the installation table.
[0049] Generally, the receptacle 2 is fixedly installed on the fixed surface 3. After the receptacle 2 is cooperatively connected with the waterproof sealing assembly, the charging interface is completely protected within the protective member 1, thereby externally sealing and protecting the charging interface to protect the internal electrical connections and electronic components from damage.
[0050] On the outer side of the housing 21 of the receptacle 2, there are also an installation space formed by the limit posts 23, a first installation position 24, and a second installation position 25 disposed close to the first installation position 24. After the receptacle 2 is cooperatively connected with the waterproof sealing assembly, the installation post 14 is correspondingly installed into the installation space between the two limit posts 23, the anti-misalignment rod 111 is correspondingly installed into the first installation position 24, and the positioning rod 112 is correspondingly installed into the second installation position 25.
