DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A socket waterproof structure comprises a socket housing 1, two socket interfaces 2 are provided on the top of the socket housing 1, a sealed cavity 5 is provided in the socket housing 1, a compression mechanism is provided in the sealed cavity 5, the compression mechanism comprises a piston plate 6 slidably connected in the sealed cavity 5, an extrusion rod 7 is fixedly connected to the top of the piston plate 6, an end of the extrusion rod 7 extends to the outside of the socket housing 1, and a first spring 8 is fixedly connected between the bottom of the piston plate 6 and the inner bottom of the sealed cavity 5;

[0022] An annular groove 3 is provided in each of the two socket interfaces 2, and a filling mechanism is provided in each of the two annular grooves 3. The ends of the two filling mechanisms extend into the compression mechanism and are communicated with each other. The filling mechanism includes an annular airbag 4 fixedly mounted on the inner side wall of the annular groove 3, and a connecting pipe 9 is connected through the end of the annular airbag 4. The end of the connecting pipe 9 extends into the sealed cavity 5 and is communicated with each other. Through the connection between the plug and the socket, the extrusion rod 7 can be driven to move downward, and the extrusion rod 7 drives the piston plate 6 to move, so that the air in the sealed cavity 5 is squeezed into the annular airbag 4 through the connecting pipe 9. When the connection is in operation, the gap between the socket interface 2 and the plug paddle is filled and protected to prevent water vapor from entering;

[0023] A plurality of first communication grooves 10 are provided in the socket housing 1, and a blocking mechanism is provided in each of the plurality of first communication grooves 10. The blocking mechanism comprises an extrusion blocking plate 12 slidably connected in the first communication groove 10, and a second spring 11 is fixedly connected between the side wall of the extrusion blocking plate 12 and the inner side wall of the first communication groove 10;

[0024] The ends of multiple blocking mechanisms all extend into the relative socket interfaces 2, and the ends of multiple first connecting grooves 10 are provided with magnetic suction mechanisms. The end magnetic poles of two relative magnetic suction mechanisms are opposite. The magnetic suction mechanism includes a mounting groove 13 opened at the end of the extrusion blocking plate 12, and the inner side wall of the mounting groove 13 is provided with a magnetic block 14. Through the arrangement of the blocking mechanism and the magnetic suction mechanism, when the socket housing 1 is not connected for use, the two extrusion blocking plates 12 can be kept in a tight state through the adsorption of the two magnetic blocks 14, which can effectively prevent water vapor from entering and improve the service life of the socket housing 1.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] In the utility model, when the staff uses the utility model, the staff connects the socket for use, and the downward displacement of the plug's pick will squeeze the magnetic block 14. The magnetic block 14 is squeezed to release the tight state and slide into the first connecting groove 10. After the plug is fully inserted and connected, the bottom end of the plug will squeeze the squeezing rod 7, and the electric piston plate 6 of the squeezing rod 7 moves downward. The piston plate 6 allows the air in the sealing chamber 5 to enter the two annular air bags 4 through the connecting pipe 9, so that the two annular air bags 4 expand and fill the gap between the socket interface 2 and the plug pick, so that it can effectively prevent water vapor from entering when used, thereby ensuring its use effect; when the staff pulls out the plug, the squeezing rod 7 leaves the squeezing of the plug to drive the piston plate 6 to reset under the elastic force of the first spring 8, and the annular air bag 4 also retracts accordingly. After the plug leaves the socket interface 2, the squeezing blocking plate 12 leaves the squeezing of the plug pick and is reset under the elastic force of the second spring 11. The two relative magnetic blocks 14 are adsorbed against each other, so that the socket interface 2 can be waterproofed when the socket is not in use, thereby improving the service life of the socket housing 1.
