Example 1

The sealing element provided by the embodiment can be used for sealing and protecting the socket in a cover closing state and a using state when the sealing element is used for an explosion-proof socket.

As shown in fig. 1, a specific embodiment of the sealing member provided for this embodiment includes: the elastic ring comprises a framework 1 and an annular elastic body 2 compounded on the framework 1, wherein the annular elastic body 2 is provided with a first sealing part 3 protruding out of the framework 1 from an inner annular wall to the central direction, and the annular elastic body 2 is also provided with a second sealing part 4 protruding out of the framework 1 from an end part to the direction far away from the first sealing part 3. The sealing member that this embodiment provided compounds annular elastomer 2 and skeleton 1, supports annular elastomer 2 through skeleton 1 to when being applied to socket seal, can avoid being extruded the dislocation by the plug, thereby guarantee the sealed effect of socket. The first sealing part 3 is used for being matched with a plug inserted into the socket, so that the sealing performance of the socket and the plug during matching can be ensured. The second sealing part 4 is used for being matched with the upper cover of the socket, and the upper cover is pressed on the second sealing part 4, so that the sealing performance of the socket in the cover sealing process can be guaranteed.
