AI Technical Summary
Existing hyperboloid spring-loaded high-current sockets are prone to attracting dust or moisture during use, leading to short circuits. Ordinary covers cannot effectively seal them, affecting safety during use.
A combined structure of a cap, inner ring, annular groove, convex ring, and expansion rubber ring is designed. When the cap is closed, the inner ring fits against the convex ring, and the expansion rubber ring diffuses and seals, ensuring that the socket body is completely sealed when not in use, preventing dust and moisture from entering.
It achieves a complete seal of the socket body, preventing dust and moisture contamination, ensuring the safety and stability of the internal structure of the socket, and the cover is automatically fixed and not easy to open, but can be easily opened during use.

[0017] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.
[0018] As Figs. 1-3 Shown, a kind of double curved surface with spring large current jack, including jack main body 1, the upper side of jack main body 1 is provided with cover 2, the inner surface of cover 2 is fixedly installed with inner ring 3, the inner circular surface of inner ring 3 is provided with annular groove 4, the left end of jack main body 1 is fixedly installed with convex ring 5, the outer circular surface of convex ring 5 is fixedly installed with expansion rubber ring 6.
[0019] By using the above technical scheme, when not using, the left end opening of jack main body 1 can be closed by cover 2, when closing, the inner circular surface of inner ring 3 will be pasted with the outer circular surface of convex ring 5, thereby make the opening closed.
[0020] Further, the inner diameter of the inner ring 3 matches the diameter of the convex ring 5, and the inflatable rubber ring 6 is located at the surface position of the convex ring 5 and matches the opening position of the ring groove 4 inside the inner ring 3.
[0021] By adopting the above technical scheme, when the inner ring 3 is attached to the convex ring 5, the inflatable rubber ring 6 will be extruded until the inner ring 3 and the convex ring 5 are completely normally combined, and then the inflatable rubber ring 6 is aligned with the ring groove 4 to expand and diffuse, tightly adhering to the inner surface of the ring groove 4, thereby further sealing the attached part of the inner ring 3 and the convex ring 5.
