Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1

[0023] Reference Figures 1 to 3 This is an embodiment of the present invention, which provides a button sealing plate, such as... Figure 1 As shown, the housing 10 and the socket 20 provided on the housing 10 are characterized in that a waterproof ring 12 with a protruding end is provided in the middle of the housing 10, and an opening 30 is provided on the inner wall of the socket 20. The opening 30 is filled with a sealing ring 40, and the sealing ring 40 extends into the inner cavity of the socket 20. In order to prevent the gap between the housing 10 and the mating structure from widening due to aging of the housing 10, which would allow moisture or dust to easily enter the interior of the housing 10 and cause failure of the internal circuit or mechanical structure, an opening 30 is provided on the inner wall of the socket 20, and a sealing ring 40 is filled in the opening 30, with the sealing ring 40 extending into the inner cavity of the socket 20. The sealing ring 40 effectively prevents moisture or dust from entering the interior of the housing 10.

[0024] It should be noted that, due to the setting of the opening 30 on the inner wall of the socket 20, and the sealing ring 40 being placed inside the opening 30, and the sealing ring 40 only extending partially into the socket 20, the sealing ring 40 can enhance the sealing effect of the housing 10 while also preventing the sealing ring 40 from affecting the connection between the housing 10 and the matching structure.

[0025] For example, the inner wall of the opening 30 is provided with an extension groove 31 extending into the receiving cavity 11 of the housing 10. The sealing ring 40 partially extends into the extension groove 31, and the receiving cavity 11 is provided with a compression piece 50 with one end extending into the extension groove 31. As the usage time increases, the sealing ring 40 is prone to aging, which can lead to a decrease in the sealing effect of the sealing ring 40. By opening an extension groove 31 in the housing 10 that communicates with the opening 30, and having the pushing end of the compression piece 50 extend into the extension groove 31, the operator can squeeze the sealing ring 40 by moving the pushing end of the compression piece 50, causing the sealing ring 40 to move into the inner cavity of the insertion port 20, thereby increasing the sealing and protective effect.

[0026] For example, the pushing end of the extrusion plate 50 is located in the inner cavity of the extension groove 31, and the pushing end of the extrusion plate 50 is connected to the extrusion block 60 located in the extension groove 31. To facilitate the extrusion block 60 to extrude the sealing ring 40, the connection between the extrusion plate 50 and the extrusion block 60 allows the user to press the extrusion plate 50 to make the extrusion block 60 extrude the sealing ring 40, causing the sealing ring 40 to deform and move towards the inner cavity of the socket 20, thereby increasing the sealing performance after the housing 10 is docked with the corresponding device.

[0027] For example, the upper end of the extrusion block 60 has inclined surfaces 61 on both sides, and each inclined surface 61 has a snap-fit ​​strip 62 on its upper side. One end of the snap-fit ​​strip 62 is adapted to two opposing snap-fit ​​slots 611 that are equally spaced on the inner wall of the extension groove 31. After the extrusion block 60 moves, if there is no limiting position, it is easy to push the extrusion block 60 back to its original position under the elastic reset of the sealing ring 40, which will affect the sealing performance of the sealing ring 40 after it docks with the housing 10 and the corresponding equipment. Therefore, inclined surfaces 61 are provided on both sides of the upper end of the extrusion block 60, and snap-fit ​​slots 611 are provided on the two inner walls of the extension groove 31. The snap-fit ​​strip 62 installed on the inclined surface 61 snaps into the snap-fit ​​slots 611 to limit the elastic reset of the sealing ring 40 after it is extruded by the extrusion block 60.

[0028] For example, the snap-fit ​​strip 62 is divided into a first part 621 connecting the inclined surface 61 and a second part 622 connecting the first part 621. The second part 622 is located at the end of the first part 621 away from the inclined surface 61, and the second part 622 snaps into the snap-fit ​​groove 611. In addition, to accommodate the decrease in elasticity caused by aging of the sealing ring 40 after long-term use, the snap-fit ​​strip 62 is configured to have an inclined first part 621 and a raised second part 622, and the second part 622 snaps into the snap-fit ​​groove 611. When the user presses the compression piece 50 again, the second part 622 and the side of the snap-fit ​​groove 611 near the sealing ring 40 are provided with a matching inclined surface 70. The second part 622 will move in the snap-fit ​​groove 611 due to the inclined surface 70 and insert into another snap-fit ​​groove 611, so that the sealing ring 40 is squeezed and then tightly adheres to the surface wall of the housing 10.
