Abstract
The utility model discloses an earth leakage protection plug including an upper cover, a pedestal and a sheet-inserting device and a wire fixing base arranged between the upper cover and the pedestal. The sheet-inserting device includes an inserting sheet penetrated from the internal part of the pedestal from the external part of the pedestal. The earth leakage protection plug also includes a first seal ring, a second seal ring and a third seal ring. The first seal ring is arranged in the upper cover. The pedestal presses the first seal ring firmly and is sealed with the upper cover. The second seal ring is sleeved on the wire fixing base and is clamped in a connection position between the wire fixing base and the pedestal. The third seal ring is sleeved on the inserting sheet and is clamped between the sheet inserting device and the pedestal. The earth leakage protection plug provided by the utility model can enhance a sealing effect and improve safety performance.
Description
Technical field
The utility model relates to plug, particularly a kind of leakage protecting plug.
Background technology
Leakage protecting plug can prevent the plug water inlet, thus the electric leakage of protection plug.Existing leakage protecting plug comprises inserted sheet device, loam cake, wire fixing base and base; because between loam cake and the base, between inserted sheet device and the base and have the fit-up gap between wire fixing base and the last cover base; so water is easy to be penetrated into from these gaps in the inserted sheet device of base inboard; thereby cause electric leakage, cause potential safety hazard.
